In 2019, the output of original seeds in Gansu Province reached more than 1 billion grains, and potato seed production has become an important crop for increasing agricultural efficiency and farmers' income in Gansu Province. Potato original seeds refer to seed potatoes that meet the corresponding quality standards produced using virus-free seedlings or test tube potatoes under isolation conditions such as insect-proof nets and greenhouses. The mature original seeds are then separated from the soil. The conventional harvesting method is to manually sort the original seeds from the soil and then bag them, and pile the soil in place, or collect the soil and bag it for a second time, and use manual sorting.

[0003] However, the existing potato original seed harvester has the following defects in use:

[0004] 1. The existing potato seed harvester cannot effectively remove the soil attached to the potatoes during use, resulting in soil accumulation and blockage between the sorting rollers;

[0005] 2. The existing potato seed harvester cannot adjust the height of the entire equipment during use, resulting in the inability to be used in field ridges of different heights in a timely manner. Utility Model Content

[0029] There are several groups of screening rollers 8 on the chain 7, and the first pulley 13 is connected to the second pulley 14 through a belt drive;

[0030] A toggle shaft 21 is rotatably installed between the side plates 2 on the front and rear sides, and a toggle triangular disk 22 is fixedly installed on the front and rear sides of the side walls of the toggle shaft 21. The arm end of the toggle triangular disk 22 is tightly attached to the chain 7. A third pulley 61 is fixedly installed on the front side of the side wall of the second sprocket shaft 6. A fourth pulley 211 is fixedly installed on the front side of the side wall of the toggle shaft 21. The third pulley 61 and the fourth pulley 211 are connected by belt transmission.

[0031] Further, a material leakage groove 41 is provided on the side wall of the bending plate 4, a limiting rod 23 is rotatably installed between the side plates 2 on the front and rear sides, a connecting sleeve 24 is slidably installed on the side wall of the limiting rod 23, a receiving groove 231 is provided on the side wall of the limiting rod 23, a return spring 232 is fixedly installed on the bottom surface of the inner cavity of the receiving groove 231, a limiting block 233 is fixedly installed on the other end of the return spring 232, a limiting groove 241 is provided on the side wall of the connecting sleeve 24, and a soil breaking base 242 is fixedly installed on the left side of the side wall of the connecting sleeve 24;

[0032] The limiting block 233 slides in the inner cavity of the receiving groove 231 and the limiting groove 241 , and there are two groups of limiting grooves 241 in total.

[0033] An extension plate 42 is fixedly installed on the right side of the lower end surface of the bending plate 4, an extension sleeve 43 is slidably installed on the side wall of the extension plate 42, a moving wheel 44 is rotatably installed on the inner side wall of the extension sleeve 43, a locking groove 421 is opened on the side wall of the extension plate 42, and a locking nail 431 is threadedly installed on the side wall of the extension sleeve 43;

[0034] The locking pins 431 slide in the inner cavity of the locking grooves 421 , and a plurality of locking grooves 421 are provided on the side wall of the extension plate 42 .

[0035] Working principle: After the user loads the tripod 3 onto the agricultural vehicle through the latch connector 31, the user manually presses the limit block 233 downward to squeeze the reset spring 232 and retract it into the receiving groove 231. At this time, the limit block 233 is completely deposited in the receiving groove 231, and the limit block 233 loses the limit of the limit groove 241. The connecting sleeve 24 can rotate on the limit rod 23. At this time, the direction of the soil breaking rod 242 fixedly installed on the connecting sleeve 24 will change, so as to realize the lifting of potato seeds at different depths in the soil ridge;

[0036] After the angle of the soil breaking base 242 is fixed, the user screws the locking nail 431 outward to make it withdraw from the locking groove 421 on the extension plate 42. At this time, the user can slide the extension plate 42 in the inner cavity of the extension sleeve 43. The total length of the extension plate 42 and the extension sleeve 43 will change, so that the height between the screening roller 8 and the soil ridge will change, thereby making the entire device suitable for soil ridges of different heights, thereby improving the practicality of the entire device.

[0037] When the potato seeds are harvested, the agricultural vehicle moves forward continuously, and the potato seeds in the soil ridge can be picked up under the action of the soil breaking device 242. At this time, the servo motor 12 is started synchronously, and the first sprocket shaft 5 rotates under the cooperation of the first pulley 13 and the second pulley 14. At this time, the chain 7 driven on the side wall of the first sprocket shaft 5 will rotate continuously, and the position of the screening roller 8 will change continuously, so that the potato seeds picked up can be transported. When the screening rollers 8 are distributed in an interval manner, the soil attached to the side wall of the potato seeds will continue to fall off, and the potato seeds will be continuously transported to the right side of the working frame 1, and finally fall from the leakage trough 41. At this time, the whole device can realize the operation of harvesting and sorting the potato seeds;

[0038] It should be noted that as the chain 7 continues to rotate, the second sprocket shaft 6 also rotates accordingly. At this time, under the cooperation of the third pulley 61 and the fourth pulley 211, the toggle shaft 21 will rotate. At this time, the arm end of the toggle triangular plate 22 fixed on the side wall of the toggle shaft 21 will indirectly collide with the chain 7, thereby shaking the screening roller 8 fixed on the chain 7 to avoid the accumulation of soil attached to the potatoes, thereby reducing the efficiency and quality of potato seed harvesting and sorting.

[0039] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
