Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product cleaning equipment, in particular to an inclination adjustment mechanism of an agricultural product cleaning mechanism. Background Art

[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties of various regions. The state stipulates that primary agricultural products refer to plants, animals and their products obtained from agricultural activities, excluding processed products. Due to the different specifications of agricultural products, cleaning equipment is needed to screen agricultural products of the same size. During the cleaning process, the inclination of the screen plate needs to be adjusted through the adjustment mechanism.

[0003] The inclination adjustment mechanism of the existing agricultural product cleaning mechanism drives one end of the sieve plate to rise and fall through a threaded transmission during use, so as to adjust the sieve plate. During the adjustment process, the above method only lifts one end of the sieve plate. Therefore, when the inclination angle to be adjusted is large, it is necessary to rotate the screw multiple times to adjust the inclination angle. This is not only time-consuming and labor-intensive, but also leads to low adjustment efficiency, affecting its adjustment performance. Therefore, there is an urgent need for an inclination adjustment mechanism for an agricultural product cleaning mechanism to solve the above problem. Utility Model Content

[0025] The connecting groove 5 is formed on the column 1, the sieve plate 2 is rotatably connected to the connecting groove 5 through the connecting shaft 6, the sieve hole 3 is formed on the sieve plate 2, and the connecting groove 5 and the connecting shaft 6 can be combined to realize the connection between the sieve plate 2 and the column 1. At the same time, during the adjustment process, the connecting shaft 6 can slide in the connecting groove 5, and the collecting frames are distributed under the three groups of sieve holes 3. During the process of selecting agricultural products, the agricultural products passing through the same sieve hole 3 fall into the collecting frame below for collection.

[0026] The transmission box is fixed to the back wall of the column 1 by bolts, the driving seat 407 is fixedly connected to the driving wheel 408, the driving wheel 408 is connected to the driven wheel 410 by a belt 409, the driving seat 407 drives the driving wheel 408 to rotate, and the driving wheel 408 drives the driven wheel 410 to rotate through the belt 409.

[0028] The other end of the transmission shaft 411 is fixedly connected to the main gear 412 , and the main gear 412 is meshed with the sub gear 413 . Both the main gear 412 and the sub gear 413 are helical gears. The transmission shaft 411 drives the sub gear 413 to rotate through the main gear 412 .
