An easily adjustable gravity-based seed sorting machine

Abstract

This utility model discloses an easily adjustable gravity-type seed sorting machine, relating to the field of seed sorting technology. It includes a frame, with a first mounting frame that can rotate longitudinally mounted on the upper end of the frame. A second mounting frame that can rotate laterally is mounted on the first mounting frame, and a sieve bed is flexibly mounted on the top of the second mounting frame. The design of this utility model uses a horizontally pushing hydraulic cylinder to drive the second mounting frame to rotate, thereby adjusting the longitudinal tilt angle of the sieve bed. A lifting hydraulic cylinder drives the first mounting frame to rotate, thereby adjusting the lateral tilt angle of the sieve bed. Furthermore, an adjusting motor drives a wind deflector to move, adjusting the airflow of the fan by changing the area of ​​the wind deflector obstructing the fan inlet. Therefore, manual adjustment of the sieve bed's tilt angle and the fan's airflow is unnecessary, reducing the workload of workers. Moreover, when processing different seeds, the equipment can be quickly debugged, improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of seed sorting technology, and in particular to a gravity-type seed sorting machine that is easy to adjust. Background Technology

[0002] Gravity-based seed sorting machines separate materials according to their specific gravity, removing heavy or light impurities from seeds. Chinese utility model patent CN2506361Y discloses a gravity-based seed sorting machine, including a frame, a feeding hopper above the frame, and a screen bed driven by a power unit below the feeding hopper. The screen surface of the screen bed is bi-directionally inclined, and a discharge hopper is installed at its lower horizontal end. The bottom of the discharge hopper has longitudinally arranged outlets for heavy materials, intermediate materials, and light materials. A fan unit is installed at the bottom of the machine, and each fan outlet under the screen bed is equipped with a uniform air distribution plate with sparse holes in the center and dense holes on the periphery.

[0003] The working principle and structure of existing gravity seed sorting machines are the same as those of gravity seed sorting machines. They work by feeding seeds onto a continuously vibrating screen bed. Under the combined action of the screen bed's vibration and the bottom fan's blowing action, the seeds are separated into layers according to their specific gravity in a vertical direction, and finally separated from the heavy material, intermediate material, and light material outlets of the discharge hopper.

[0004] However, the sieve bed angle and the air volume of the bottom fan in the existing gravity seed sorting machine are all manually adjusted. The adjustment process is time-consuming and laborious, and the air volume of the damper needs to be manually readjusted when processing different seeds, which affects production efficiency.

A rack 14 is fixedly installed on the top of the moving table 12. A gear 15 that meshes with the rack 14 is fixedly installed on the support shaft 8 on the right side of the first mounting frame 2. When it is necessary to adjust the longitudinal tilt angle of the screen bed 5, the horizontal hydraulic cylinder 13 drives the moving table 12 to move along the slide rail 10, so that the rack 14 drives the gear 15 to rotate. With the cooperation of the rack 14 and the gear 15, the first mounting frame 2 rotates around the support shaft 8, thereby realizing the longitudinal angle adjustment of the screen bed 5.

[0021] In this embodiment, a first connecting seat 16 is fixedly installed on the left side of the second mounting frame 3, and a second connecting seat 17 is rotatably installed on the first connecting seat 16.

The buffer components 20 are composed of spring steel sheets and springs. A connecting frame 21 is fixedly installed on the top of each set of buffer components 20.

[0023] In this embodiment, several sets of fans 6 are fixedly installed on the base plate of the frame 1. The fans 6 are volute fans. A mounting plate 23 is provided between the fans 6 and the first mounting frame 2. The mounting plate 23 is fixedly installed on the inner wall of the frame 1.

Several sets of ventilation openings 26 are located on the bottom wall of the air guide hood 25, corresponding to the positions of the fans 6. The air outlet of each set of fans 6 is fixedly installed at the ventilation opening 26. The airflow generated by the fans 6 is blown towards the screen bed 5 through the air guide hood 25. The blades of the fans 6 are connected to each other through a drive shaft 27. A first transmission wheel 28 is fixedly installed at one end of the frame 1 near the outer side. A drive motor 29 is fixedly installed on the base plate of the frame 1. A second transmission wheel 30 is fixedly installed at the output end of the drive motor 29. The second transmission wheels 30 are connected to each other by a transmission belt 31. The drive motor 29 and the fan 6 are driven by a belt. In actual production, depending on the size of the seed sorting machine, a single motor can drive all the fans 6 to work, or motors can be set on both sides of the frame 1, and the motors on both sides can drive the fans 6 closest to their respective sides to work. That is, multiple sets of fans 6 can be driven by a single drive motor 29 to work, so as to reduce the production cost of the equipment.

[0024] In this embodiment, the drive mechanism corresponds one-to-one with the air regulating plate 7. The drive mechanism includes an adjusting motor 32, which is fixedly installed on the bottom outer wall of the frame 1. The output end of the adjusting motor 32 is fixedly connected to a lead screw 33. The top of the air regulating plate 7 is fixedly installed with a lead screw nut 34 that matches the lead screw 33. The air regulating plate 7 has a clearance groove 35 that corresponds to the position of the transmission shaft 27. The upper and lower sides of the clearance groove 35 are fixedly installed with slide seats 36. A smooth rod 37 is slidably installed on the slide seat 36. The smooth rod 37 is fixedly installed on the frame 1. When it is necessary to adjust the air volume of the fan 6, the adjusting motor 32 drives the lead screw 33 connected to it to rotate. With the cooperation of the lead screw 33 and the lead screw nut 34, the air regulating plate 7 moves along the smooth rod 37. The air volume of the fan 6 is adjusted by changing the blocking area of ​​the air regulating plate 7 on the air inlet of the fan 6. The position of each set of air regulating plates 7 can be adjusted individually to achieve air volume adjustment in different areas of the screen bed 5.

[0025] During debugging, when the longitudinal tilt angle of the sieve bed 5 needs to be adjusted, the operator starts the horizontal hydraulic cylinder 13 through an external controller. The horizontal hydraulic cylinder 13 drives the second mounting frame 3 to rotate, thereby adjusting the longitudinal tilt angle of the sieve bed 5. When the lateral tilt angle of the sieve bed 5 needs to be adjusted, the operator starts the lifting hydraulic cylinder 4 through an external controller. The lifting hydraulic cylinder 4 drives the first mounting frame 2 to rotate, thereby adjusting the lateral tilt angle of the sieve bed 5. When the air volume of the bottom fan needs to be adjusted, the operator starts the adjusting motor 32 through an external controller. The adjusting motor drives the air regulating plate 7 to move, thereby adjusting the air volume of the fan 6 by changing the area of ​​the air regulating plate 7 blocking the air inlet of the fan 6. Therefore, there is no need to manually adjust the tilt angle of the sieve bed 5 and the air volume of the fan 7, thereby reducing the workload of the workers. In addition, when processing different seeds, the equipment debugging work can be completed quickly, which is conducive to improving production efficiency.
