Embodiment 1

[0026] refer to Figure 1-2 , a screening system for soil improvement, comprising a box body 1, a plurality of feet are symmetrically fixed by bolts on both sides of the bottom of the box body 1, the top of the box body 1 is penetrated, and the same circle is fixed by bolts on the inner walls of the two ends of the box body 1. Cylinder 2, the inner wall of the rear end of the cylinder 2 is fixed with two net collection cylinders 3 distributed up and down by bolts, and the outer wall of the net collection cylinder 3 is fixed with a coil spring, and the other side of the coil spring is fixed with a screen 4 by bolts. Openings 10 are opened on both sides of the cylinder 2, and the screen 4 extends out of the opening 10, and a pull plate 5 is fixed on the outside by bolts. 6. The two pull plates 5 are respectively slidingly connected to the bottom of the inner wall of the corresponding first discharge port 6. Both sides of the box body 1 are fixed with a fixed rod 7 by bolts, and ...

Embodiment 2

[0031] refer to Figure 2-3 , a screening system for soil improvement. The top of the material guide plate 11 is fixed with a plurality of pushing plates 19 by bolts. It is inclined downward toward the side of the second discharge port 15, so as to accelerate the dropping of soil and improve the overall screening efficiency.

[0032] In the present invention, a chute 16 is opened on the side of the box body 1 close to the first electric push rod 12, and a slider 17 is slidably connected in the chute 16, and a second spring is fixed between the slider 17 and the inner wall of the chute 16 by bolts. 18. The first electric push rod 12 and the slider 17 are rotationally connected through bearings, thereby further accelerating the dropping of soil and improving the overall screening efficiency.

[0033] During use, when the material guide plate 11 rotates back and forth, the earth can be shaken off. By setting the pusher plate 19, the pusher plate 19 is set to a step shape, so tha...

Embodiment 3

[0035] refer to Figure 3-5 , a screening system for soil improvement, the first outlet 6 is slidably connected with a fixed block, the pull plate 5 is slidably connected to the top of the fixed block, the fixed rod 7 is fixed to the outside of the fixed block by bolts, and the inside of the fixed block is provided with a movable groove , the first pole 23 and the second pole 24 are respectively connected with the first pole 23 and the second pole 24 through the bearing rotation in the movable groove, and the inner side of the second pole 24 is provided with an embedding groove 25, and the inner wall of the embedding groove 25 is fixed with a fourth spring 26 by a bolt, and the fourth spring 26 and the first pole 23 are fixedly connected by bolts, and a driving mechanism is arranged in the first discharge port 6 .

[0036] In the present invention, the drive mechanism is respectively fixed with a second electric push rod 22 and a third spring 21 by bolts at the bottom of the i...

Abstract

The invention belongs to the technical field of soil improvement and particularly relates to a screening system for soil improvement. In order to solve the problem that an existing device is low in screening efficiency, the following scheme is now put forwards. According to the scheme, the screening system comprises a box body, a cylinder is fixed between the inner walls of the two ends of the boxbody, two net collecting cylinders are fixed to the inner wall of the rear end of the cylinder, and coil springs are wound and fixed to the circumferential outer walls of the net collecting cylinders; and screens are fixed to the other sides of the coils springs., openings are formed in the two sides of the cylinder, pull plates are fixed to the outer portions of the screens, first discharging openings are formed in the two sides of the box body in a penetrating manner, the two pull plates are connected with the bottoms of the inner walls of the corresponding first discharging openings correspondingly in a sliding manner, fixing rods are fixed to the two sides of the box body, motors are fixed to the outer sides of the fixing rods, and output shafts of the motors are connected with cams.According to the screening system for soil improvement, the cams impact the pull plates to drive the screens to stretch and extend towards the two sides, and the screens are reset under the action ofthe coil springs, so that the screens form repeated drawing motion, relative motion is formed between the screens and soil, and the screening effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a screening system for soil improvement. Background technique [0002] Soil improvement is the process of taking corresponding physical, biological or chemical measures to improve soil properties, soil fertility, crop production, and the soil environment for human survival in response to the poor texture and structure of the soil. In the process of agricultural planting, the soil is One of the essential conditions, natural crops are rich in nutrients, and soil cultivation can promote the complete continuation of the ecological chain. [0003] In the process of soil improvement, it is necessary to screen the crushed stones in the soil, and screen the crushed stones and soil, so as to maintain the good performance of the soil and facilitate planting. In the prior art, vibrating sieves are generally used for screening, and the screening efficiency is low. Therefore, corres...
