干篩法土工布有效孔徑測定儀主要有機座、上蓋、回轉機構、振擊機構、夾緊機構與套篩組成，主要結構說明如下。

回轉機構

電動機（1A）與離合體（146A）轉動軸套（14 ）一得齒輪（13 ）通過齒輪（152A）而帶動齒輪軸（137A）上的小斜齒輪（141A）轉動，小斜齒輪帶動大斜齒輪（97A）使以鍵與之連接的空心的主偏心軸（74A）旋轉，從而帶動以120度均布與上蓋（3A）上的三個副偏心軸（1 ）回轉，使整個活動架得到半徑等于偏心距正圓平面搖動。

振擊機構

在活動架得到正圓平面搖動的時候，通過以螺釘與之固連的主偏心上蓋（70A）帶動打擊軸（109A）回轉，使打擊軸上的上端面凸輪（0 ）轉動，同時齒輪由（137A）上的齒輪（164A）通過齒輪（157A）（159A）帶動齒輪軸100下端面凸輪（107A）慢速旋轉，上下端面凸輪同向轉動產生軸向位移造成打擊軸往上頂起，直到上下平面凸輪缺口處 往下掉而得到振擊運動。壓縮彈簧（78A）的作用是增強打擊力量之用。

加緊結構

旋轉扭緊螺栓（5 ）可使退撥落螺母（54A）高軸向運動，使篩蓋固定頂桿（47A）往外伸長從而頂死篩蓋倒桿達到固定篩蓋的目的。

潤滑系統(tǒng)

本結構潤滑簡單，軸承全部用潤滑脂——黃油潤滑，而齒輪和偏心軸與主（付）偏心軸的潤滑都是飛濺潤滑。注：油咀（20A）可在付偏心出加機油，每班必須加機油一次，以防飛濺不到。主機必須加機油10kg,如缺潤滑油，潤滑系統(tǒng)出現故障，本廠概不負責。

自動停車裝置

電源開關接通后，用定時器通過中間繼電器控制電動機長期運轉或定時運轉，停止運轉。為了保證安全工作，本機點擊托盤裝有接地線螺釘，用戶必須按規(guī)程接地。

The dry sieve method for measuring the effective aperture of geotextiles is mainly composed of a machine base, an upper cover, a slewing mechanism, a vibrating mechanism, a clamping mechanism and a sleeve screen. The main structure is described below.

Slewing mechanism

The motor (1A) and the clutch body (146A) rotate the shaft sleeve (14 ), and the gear (13 ) drives the small helical gear (141A) on the gear shaft (137A) to rotate through the gear (152A). The gear drives the large helical gear (97A) to rotate the hollow main eccentric shaft (74A) connected by the key, thereby driving the three auxiliary eccentric shafts (1 ) evenly distributed on the upper cover (3A) at 120 degrees. Rotate to make the entire movable frame shake with a radius equal to the eccentricity from the perfect circular plane.

Vibration mechanism

When the movable frame is shaken by a perfect circular plane, the main eccentric upper cover (70A) connected with the screw drives the striking shaft (109A) to rotate, so that the upper end cam (0 ) on the striking shaft rotates, and The gear is driven by the gear (164A) on (137A) through the gear (157A) (159A) to drive the lower end cam (107A) of the gear shaft 100 to rotate slowly. The upper and lower end cams rotate in the same direction to generate axial displacement, which causes the striking shaft to rise upward. , Until the upper and lower flat cam notches fall down and get the percussion motion. The role of the compression spring (78A) is to increase the strike force.

Tightening structure

Rotating and tightening the bolt (5 ) can make the high-axle movement of the pull-down nut (54A), so that the fixed cover (47A) of the sieve cover is extended outward, so that the inverted cover of the sieve cover is fixed.

Lubrication system

This structure is simple in lubrication. All bearings are lubricated with grease-butter, while the lubrication of gears, eccentric shafts and main (sub) eccentric shafts are all splash lubrication. Note: The oil nozzle (20A) can be used to add oil at the eccentric position. You must add oil once per shift to prevent splashing. The main engine must be filled with 10kg of oil. Our factory will not be responsible for any failure of the lubrication system or lubrication system.

Automatic parking device

After the power switch is turned on, the timer is used to control the motor for long-term operation or timing operation through the intermediate relay to stop the operation. In order to ensure safe work, the click tray of this machine is equipped with a ground wire screw, and the user must ground according to the regulations.

干篩法土工布有效孔徑測定儀安裝：

可以不用水泥基礎，直接安放水泥地面上開動，也可以安裝在水泥基礎上，基礎螺釘尺寸如圖，其厚度300mm,基礎露地面高度及大小或與地面相平，根據具體使用需要而定，按電工規(guī)程安裝電路與接地，安裝完畢，接通電源后電動機回轉方向與箭頭相同 有振擊運動，若相反，則電機空運轉，此時可換接頭線，才能正常開動。

使用和保養(yǎng)：

開機前，擰出（15 ）上螺塞，加足潤滑油至螺孔面，裝套篩時先將扭緊螺栓（5 ）左旋以松開篩蓋固定頂桿（47A）然后連同篩蓋（43A）往上提，然后右旋固定可置套篩托盤（62A）上在將扭緊螺栓左右松開往下壓并右旋之使固定緊即可工作。根據工作需要，時間任意設置，需要中途停機，應切斷電源開關。此儀器保養(yǎng)簡單，每隔3-6個月更換墊子出一次，使用時注意避免蓋板上的七根倒桿的變形。

結束注意：

必須注意防潮，防腐蝕，使用兩年左右需清洗加油一次。

Installation of dry sieve geotextile effective aperture tester

It can be installed directly on the cement floor without using the cement foundation, or it can be installed on the cement foundation. The size of the foundation screw is shown in the figure, its thickness is 300mm, the height and size of the foundation exposed on the ground or the level is flat. The electrician regulations install the circuit and ground. After installation, the direction of rotation of the motor is the same as the arrow after the power is turned on. There is vibration motion. If it is the opposite, the motor runs dry. At this time, you can change the connector line to start normally.

Operation and maintenance of dry sieve geotextile effective aperture tester

Before starting the machine, unscrew the upper plug (15 ) and add enough oil to the surface of the screw hole. When installing the screen, turn the tightening bolt (5 ) to the left to loosen the screen cover and fix the top post (47A). Lift up the sieve cover (43A), then turn the fixed set screen tray (62A) to the right, loosen the tightening bolts left and right, press down, and turn the right to make the fixing work. The time can be set arbitrarily according to the needs of the work, and the power switch should be turned off if it needs to be stopped halfway. This instrument is easy to maintain. Replace the mat every 3-6 months. When using it, be careful to avoid deformation of the seven inverted bars on the cover.

End of dry sieve geotextile effective aperture tester

Must pay attention to moisture and corrosion, you need to clean and refuel once in about two years.
