Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal equipment, in particular to mechanical impurity removal equipment for rapeseed harvesting. Background Art

[0002] Mechanics is a general term for both machines and mechanisms. A machine is a tool or device that helps people reduce the difficulty or effort of their work. Objects like chopsticks, brooms, and tweezers are considered machines; they are simple machines. Complex machines, on the other hand, are composed of two or more simple machines. These more complex machines are usually called machines. From the perspective of structure and motion, there is no distinction between mechanisms and machines, and they are generally referred to as machines.

[0003] When harvesting rapeseed, impurities in the rapeseed need to be removed. Currently, this is done manually, which is not only incomplete but also time-consuming and labor-intensive.

[0004] For example, Chinese patent CN113522740A discloses a mechanical impurity removal device for rapeseed harvesting, which has the effect of comprehensive impurity removal and saves time and effort. The rapeseed is first impurified by shaking the frame, and then the rapeseed is impurified for the second time by a blowing device, making the rapeseed impurity removal more comprehensive. In addition, the device only requires people to remove the remaining impurities, achieving the effect of saving time and effort.

[0005] However, after the device pours rapeseed into the frame, the rapeseed in the frame is unevenly distributed, resulting in excessive accumulation of rapeseed in some areas and insufficient distribution of rapeseed in some areas, thereby affecting the rapeseed impurity removal efficiency.

[0006] For this reason, we urgently need to provide a kind of rapeseed harvesting and mechanical impurity removal equipment. Utility Model Content

[0013] Preferably, the two side panels on the right side are located on the right side of the mounting frame

[0014] , so that the movable frame can be moved to the rightmost side of the guide rod, so that the filter can be rotated around the left side of the mounting frame to pour out the impurities on the top of the filter.

[0015] Preferably, the side of the telescopic part 2 away from the side plate is fixedly connected to one side of the movable frame, and the telescopic part 2 pushes the movable frame to drive the rake plate to move left and right, thereby evenly spreading the rapeseed to be cleaned accumulated on the top of the filter screen and making it evenly distributed on the top of the filter screen.

[0016] Preferably, the highest point of the cam contacts the bottom of the filter screen, and the motor drives the connecting rod to rotate, which drives the cam to rotate when the cam rotates, so that the cam hits the bottom of the filter screen, causing the filter screen to vibrate, thereby accelerating the removal of impurities from the rapeseed.

[0032] The material digging unit includes a side plate 401, a guide rod 402, a movable frame 403, a telescopic member 1 404, a rake plate 405 and a telescopic member 2 406. The side plate 401 is fixedly installed around the side of the mounting frame 1. The two side plates 401 on the right side are located on the right side of the mounting frame 1, so that the movable frame 403 can be moved to the rightmost side of the guide rod 402, thereby facilitating the rotation of the filter screen 3 around the left side of the mounting frame 1 to pour out the impurities on the top of the filter screen 3. The guide rod 402 is fixedly installed on the adjacent side of the left and right side plates 401. The front and rear ends of the movable frame 403 are slidably connected to the outside of the guide rod 402. The telescopic member 1 404 is fixedly installed on the movable frame 40 3 top, the telescopic member 1 404 is an electric push rod, the harrow plate 405 is fixedly installed at the bottom of the telescopic member 1 404, the telescopic member 2 406 is fixedly installed on the left side of the right side plate 401, the telescopic member 2 406 includes a hydraulic cylinder and a hydraulic rod, the hydraulic cylinder is fixedly installed on the left side of the right side plate 401, the hydraulic rod is installed at the output end of the hydraulic cylinder, the side of the telescopic member 2 406 away from the side plate 401 is fixedly connected to one side of the mobile frame 403, and the telescopic member 2 406 pushes the mobile frame 403 to move the harrow plate 405 left and right through the telescopic member 2 406, thereby evenly spreading the rapeseed to be cleaned accumulated on the top of the filter screen 3 and making it evenly distributed on the top of the filter screen 3.

[0033] The vibration unit includes a motor 501, a connecting rod 502 and a cam 503.

When the cam 503 rotates, the cam 503 is driven to rotate, so that the cam 503 hits the bottom of the filter 3, causing the filter 3 to vibrate, thereby accelerating the removal of impurities from the rapeseed.

[0034] Example 2:

[0035] On the basis of Example 1: the locking unit includes a bracket 601, a lock 602 and a fixed block 603. The bracket 601 is fixedly installed on the right side of the filter screen 3.

[0036] Example 3:

[0037] On the basis of the first embodiment: the two left side plates 401 are located on the left side of the mounting frame 1, so that when the rake plate 405 moves to the leftmost end of the guide rod 402, the rake plate 405 just moves out of the filter screen 3, making it easy to push impurities out of the left side of the filter screen 3.

[0038] When in use, the rapeseed to be cleaned is poured into the filter 3, and then the telescopic member 1 404 is started to drive the rake plate 405 to move up and down to a suitable height, and then the telescopic member 2 406 and the motor 501 are started, and the mobile frame 403 is pushed to move left and right along the guide rod 402 by the telescopic member 2 406, and the rapeseed on the top of the filter 3 is spread evenly so that it is evenly distributed on the top of the filter 3. The motor 501 drives the connecting rod 502 to rotate, and when the cam 503 rotates, it drives the cam 503 to rotate, so that the cam 503 hits the bottom of the filter 3, causing the filter 3 to vibrate, thereby accelerating the cleaning of the rapeseed. During the movement of the rake plate 405 from right to left, the rake plate 405 pushes some impurities out of the left side of the filter 3, thereby reducing impurities inside the rapeseed, reducing the obstruction of impurities to the rapeseed, improving the efficiency of the rapeseed passing through the filter 3, and further improving the rapeseed impurity removal efficiency. The rapeseed after impurities are removed by the filter 3 falls into the collection frame 2 for collection. Finally, the movable frame 403 is moved to the rightmost side of the guide rod 402, and the lock buckle 602 is rotated to separate from the fixed block 603. Then, the right end of the filter 3 is pushed to make the filter 3 rotate around the mounting frame 1 to pour out the impurities inside the filter 3, thereby completing the rapeseed impurity removal.
