[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example

[0034] Reference Figure 1-7 The utility model provides an embodiment: a root agricultural product harvester, comprising a support frame 11, a plurality of shafts 6, two side panels 9, a guardrail plate 10, four wheels 13, a blade motor 4, a belt motor 7 and two loosening shovels 16, a harvesting box 12 is arranged on one side of the upper end surface of the guardrail plate 10, and wheel axles 18 are penetrated on both sides of the lower sides of the two side panels 9;

[0035] A blade body 3 is fixedly arranged at the output end of the blade motor 4, and a plurality of shafts 6 are fixedly sleeved with pulleys 2 on their outer end surfaces, and a belt 5 is arranged between the plurality of pulleys 2;

[0036] When the device is used, the soil is loosened by the loosening shovel 16, and then the harvester is pushed forward, and the belt 5 on the transmission shaft performs relative movement. Under the action of friction, it moves along the direction of the chain movement. At this time, the vertical upward component force is greater than the sum of the gravity of the carrots and potatoes and the friction between the carrots, potatoes and the soil. The carrots and potatoes are slowly pulled out and transmitted to the separation device, and finally fall into the harvest box 12.

[0037] The blade motor 4 is fixedly arranged on the middle support rod of the support frame 11, the belt motor 7 is fixedly arranged on the rear support rod of the support frame 11, the upper side end of the belt motor 7 is connected to the lower side of one of the multiple shafts 6 through a gear, and multiple first nuts 14 are arranged on the support frame 11, and the four wheels 13 are respectively sleeved on the outer end surfaces of the two wheel shafts 18 at the two sides, and the outer end surfaces of the two wheel shafts 18 are both threadedly sleeved with second nuts 17 at the two sides;

[0038] The loosening device is composed of two symmetrical arrows that expand outward. The front end of the device changes from narrow to wide, which reduces the pulling force of the rear mechanism on the carrot. The soil loosening device is a key component of the carrot and potato harvester. The conveying device mainly pulls carrots and potatoes out of the soil and transmits them to the separation device. The introduction conveying device first gathers the stems and leaves of carrots and potatoes through the gathering structure, and then introduces them into the conveying device. At this time, the vertical upward component force is greater than the sum of the gravity of carrots and potatoes and the friction between carrots, potatoes and the soil. The carrots and potatoes are slowly pulled out and transmitted to the separation device. The entire introduction conveying device consists of a gathering structure, a chain, a gear and a transmission shaft. The overall shape of the gathering structure is trapezoidal, wide in front and narrow in the back. Its main function is to gather the stems and leaves of carrots and potatoes and gather them in a straight line for subsequent processing. Studies have shown that the lowest end of the stems and leaves of carrots and potatoes and the highest end of the roots are exposed above the ground by 0 to 27 mm. In order to ensure that the gathering device does not come into direct contact with the roots, prevent damage to carrots and potatoes, and reduce the residual length of the stems of carrots and potatoes after cutting, this study sets the distance of the gathering structure from the ground to 30 mm, and it can be adjusted according to specific circumstances. After the gathering structure gathers the stems and leaves of carrots and potatoes, as the carrot and potato harvester moves forward, the carrots and potatoes will follow the introduction device into the conveyor. The friction and clamping force between the special-shaped belt 5 in the conveyor and the stems and leaves of carrots will ensure that the carrots and potatoes will not fall during the backward and upward movement.

[0039] The blade motor 4 on the support frame 11 drives the blade body 3 to rotate, and the rotating blade body 3 cuts the roots of carrots and potatoes. The started belt motor 7 can drive the shaft 6 to rotate through gears, and the rotating shaft 6 transmits through gears to allow the two belts 5 to transport carrots and potatoes. The support frame 11 is spliced ​​by multiple support rods, and the multiple support rods are fixed by first nuts 14 and bolts. The wheel 13 is supported by the wheel shaft 18, and the wheel 13 is restricted on the wheel shaft 18 by the second nut 17, which effectively prevents it from falling from the wheel shaft 18.

[0040] The support frame 11 is fixedly arranged on the upper end surface of the guardrail plate 10, and the guardrail plate 10 is fixed between the two side plates 9 through a plurality of angle codes 8. The front side of the lower end surface of the support frame 11 is fixedly arranged with a connecting piece 1 on both sides, and two loosening shovels 16 are respectively fixedly arranged on the lower end surfaces of the two connecting pieces 1. A plurality of bearing seats 15 are fixedly arranged on the support frame 11, and a plurality of shafts 6 are respectively rotatably arranged on the inner walls of the plurality of bearing seats 15;

[0041] The support frame 11 is supported by the guardrail plate 10, and the guardrail plate 10 is fixed to the side plate 9 by the angle code 8, so that the guardrail plate 10 is fixed more stably and firmly, and the loosening shovel 16 is fixedly connected by the connecting piece 1, so that the loosening shovel 16 can work stably to turn over and loosen the soil. A plurality of bearing seats 15 are arranged on the support frame 11, and a shaft rod 6 is arranged inside the bearing seat 15. The shaft rod 6 can drive the pulley 2 to rotate, thereby driving the belt 5 to rotate, and the two belts 5 clamp the potatoes and carrots to realize transmission.

[0042] Working principle: The soil loosening device is used to loosen the soil around carrots and potatoes, reduce the resistance when pulling out carrots and potatoes, prevent the transmission of carrots and potatoes from being blocked, damage to fruit leaves, missed harvesting, etc. due to excessive resistance, ensure work efficiency, avoid machine damage, and reduce energy consumption during transmission. The soil loosening shovel 16 in front of the harvester shovels the soil to loosen the soil, so that the rotating belt 5 can stably pull out carrots and potatoes, and then the potatoes and carrots are raised to the position of the blade body 3 through the transmission of the belt 5. The blade body 3 driven by the blade motor 4 cuts the rhizomes and finally puts them into the harvesting box 12.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
