Description

Technical Field

[0001] The utility model relates to the field of auxiliary harvesting of potato harvesters, in particular to a soil removing and conveying structure of a potato harvester. Background Art

[0002] During the potato harvesting process, soil blocks will be attached to the surface of the harvested potatoes, and these soil blocks cannot be packaged together with the potatoes. Therefore, the soil blocks on the surface of the potatoes need to be initially removed before collecting the harvested potatoes. The existing soil removal structure removes the soil blocks on the surface of the potatoes by means of a high-frequency vibration conveyor belt or a conveyor rod. However, in the existing method, under the high-frequency vibration state, the potatoes will jump and collide. Although the soil blocks on the surface of the potatoes are removed, the potato skin will be damaged. The potatoes with damaged skin will be more easily oxidized and rotten, affecting transportation and sales, and affecting the aesthetics during the sales process. In the prior art, a brush is also used to scrub the surface of the potatoes, but the brush will also damage the potato skin. Utility Model Content

[0021] Example: As shown in the attached Figures 1 to 5 As shown, a soil removing and conveying structure of a potato harvester comprises two conveying anti-slipping side plates 1, a fixed crossbeam 2 is fixedly connected between the two conveying anti-slipping side plates 1, a potato conveying assembly 3 is connected between the two conveying anti-slipping side plates 1, the potato conveying assembly 3 comprises a plurality of conveying rods 32, a soil removing shaking component 4 is connected to one side of the two conveying anti-slipping side plates 1, the soil removing shaking component 4 comprises two fixed mounting plates 41, the two fixed mounting plates 41 are respectively fixedly connected to the two conveying anti-slipping side plates 1, a power assembly 42 is connected between the two fixed mounting plates 41, the power assembly 42 comprises two mounting shaft seats 421, the two mounting shaft seats 421 are respectively fixedly connected to the two fixed mounting plates 41, a rotating rod 422 is rotatably connected to the two mounting shaft seats 421, a shaking assembly 43 is connected to the rotating rod 422, a connecting crossbeam 44 is fixedly connected between the two fixed mounting plates 41, and an anti-jump assembly 45 is connected between the connecting crossbeam 44 and the plurality of conveying rods 32.

[0022] The potato conveying assembly 3 includes a mounting rod 31, the two ends of which are fixedly connected to the two conveying anti-detachment side plates 1, respectively, and the mounting rod 31 is rotatably connected to a plurality of conveying rods 32. The mounting rod 31 can be used to connect the conveying rod 32, and the end of the mounting rod 31 is fixedly connected to the conveying anti-detachment side plate 1, so that the plurality of conveying rods 32 can be rotated independently, so that two adjacent conveying rods 32 can be staggered up and down, thereby separating the soil on the surface of the potato. The surface of the conveying rod 32 can be covered with a soft rubber sheath, which can prevent damage to the potato skin.

[0023] A plurality of clearance limiting cylinders 33 are sleeved on the installation rod 31, and the plurality of clearance limiting cylinders 33 and the plurality of transfer rods 32 are arranged alternately. By arranging the plurality of clearance limiting cylinders 33, the plurality of transfer rods 32 can be better limited, so as to ensure the accuracy of the installation positions of the plurality of transfer rods 32.

[0024] One end of the rotating rod 422 is fixedly connected with an input belt pulley 423, and the input belt pulley 423 drives the rotating rod 422 to rotate by belt transmission of input power. By arranging the input belt pulley 423, an external power source can be connected through a belt, and the input belt pulley 423 is driven to rotate by belt transmission, so as to drive the rotating rod 422 to rotate. The rotating rod 422 can ensure a relatively smooth rotation process under the action of the two mounting shaft seats 421.

[0025] The shaking assembly 43 includes a plurality of eccentric wheels 431. Eccentric grooves 432 are formed in the plurality of eccentric wheels 431. The plurality of transfer rods 32 are respectively in tangential contact with the eccentric grooves 432 in the plurality of eccentric wheels 431. The plurality of eccentric wheels 431 are fixedly connected with the rotating rod 422. The axial angle deviation between two adjacent eccentric wheels 431 is set to 90 degrees. By setting the axial angle deviation between two adjacent eccentric wheels 431 to 90 degrees, the two adjacent transfer rods 32 can be respectively in a staggered up-and-down state. When the rotating rod 422 rotates to drive the plurality of eccentric wheels 431 to rotate, the two adjacent transfer rods 32 will move up and down alternately, so that the soil attached to the surface of the potatoes falls off. And because the moving speed of the transfer rods 32 is low, the surface of the potatoes will not be damaged.

[0026] A plurality of clearance limiting rings 433 are fixedly sleeved on the rotating rod 422, and the plurality of eccentric wheels 431 and the plurality of clearance limiting rings 433 are arranged alternately. By arranging the plurality of clearance limiting rings 433, the installation positions of the eccentric wheels 431 can be better limited, so as to ensure the accuracy of the installation positions of the eccentric wheels 431.

[0027] The anti-jumping assembly 45 includes a plurality of rod fixed rings 451 and a plurality of cross beam fixed rings 452. The plurality of rod fixed rings 451 are respectively fixedly connected with the lower surfaces of the transfer rods 32, and the plurality of cross beam fixed rings 452 are all fixedly connected with the upper surfaces of the connecting cross beams 44. Anti-jumping springs 453 for tightening the transfer rods 32 are connected between the plurality of rod fixed rings 451 and the plurality of cross beam fixed rings 452. By arranging the cross beam fixed rings 452 and the rod fixed rings 451, the anti-jumping springs 453 can be conveniently installed, and the anti-jumping springs 453 can be prevented from falling off while being able to bear the tension. By arranging the anti-jumping springs 453, the transfer rods 32 can be prevented from jumping under the rotation of the eccentric wheels 431. The jumping transfer rods 32 will damage the surface of the potatoes and affect the quality and ornamental value of the potatoes.

[0028] Working principle: the harvested potatoes are transported between the two conveying anti-slip side plates 1 through the conveyor belt, and the potatoes fall on multiple conveying rods 32. Potatoes with a volume smaller than the gap between the two conveying rods 32 will fall from the gap between the two conveying rods 32, thereby realizing the separation of potatoes with smaller volume. Potatoes with larger volume will move downward with the inclination angle of the conveying rod 32, and soil will remain on the surface of the newly harvested potatoes. The power source drives the input pulley 423 to rotate through the belt transmission, and the input pulley 423 drives the rotating rod 422 to rotate, thereby rotating the multiple eccentric wheels 431 on the rotating rod 422, and the two adjacent eccentric wheels 431 The axial displacement is 90 degrees, and the transmission rod 32 is arranged in tangential contact with the eccentric groove 432 in the eccentric wheel 431. The two adjacent transmission rods 32 move up and down alternately, so as to separate the soil on the surface of the potato. The anti-jump spring 453 is provided to apply a downward pulling force to the transmission rod 32, so that the transmission rod 32 can always maintain a tangential contact with the eccentric groove 432, thereby preventing the transmission rod 32 from jumping up during the up and down movement. The jumping transmission rod 32 is likely to cause damage to the surface of the potato. The anti-jump component 45 can ensure that the surface of the potato is not damaged, thereby ensuring the aesthetics of the potato.
