[0033] In the description of the present utility model, the "first feature" and "second feature" may include one or more of such features. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0034] As Figures 1-6 shown, a new type of automated radish harvester includes: a harvesting vehicle 1, a soil loosening mechanism 2, a clamping and conveying mechanism, a soil cleaning mechanism 4, a root and leaf separation mechanism 5, and a collection mechanism 6.

[0035] A crawler chassis 12 is provided at the bottom of the frame 11 of the harvesting vehicle 1. Adopting the crawler running form, it has good cross-country performance and stability, ensuring good passability of the machine in complex terrains such as mountains and hills. At the same time, it is easier to achieve actions such as turning with the crawler type.

[0036] Furthermore, the device uses four small crawlers instead of large crawlers, which can provide better stability and balance. The small crawlers have better flexibility and adaptability, and can more easily adapt to complex terrains. The small crawlers are easier to replace and maintain, reducing the maintenance cost.

[0037] As Figure 1 and Figure 3 shown, the soil loosening mechanism 2 includes a bucket 21, shovel teeth 22 and a first drive assembly. The bucket 21 is arranged at the front of the vehicle frame 11. A plurality of shovel teeth 22 are detachably installed on the front side of the bucket 21. The first drive assembly is connected to the bucket 21 to drive the bucket 21 to vibrate up and down.

[0038] The first drive assembly in the device includes a first motor 23, a crank 24, a connecting rod 25, a sliding rod 26 and a guide sleeve 27. The first motor 23 is fixedly arranged on the vehicle frame 11. The first motor 23 is fixedly connected to the crank 24. The crank 24 is rotatably connected to the connecting rod 25. The connecting rod 25 is rotatably connected to the sliding rod 26. The guide sleeve 27 is fixedly arranged on the vehicle frame 11. The sliding rod 26 passes downward through the guide sleeve 27 and is rotatably connected to the bucket 21.

[0039] Thus, during operation, first, according to the actual radish planting situation, disassemble and adjust the spacing between the shovel teeth 22. Then, the shovel teeth 22 will be inserted into the soil on both sides of the radish. After that, the first motor 23 drives the sliding rod 26 to move up and down through the crank 24 and the connecting rod 25, and then drives the bucket 21 to vibrate up and down, so as to loosen the soil on both sides of the radish through vibration, facilitating the subsequent clamping and conveying mechanism to easily pull out the radish.

[0040] In practical applications, for example, a number of through holes are provided on the bucket 21, and bolts are provided on the shovel teeth 22. The bolts pass through one of the through holes and are connected to nuts, so as to realize the detachable connection between the shovel teeth 22 and the bucket 21. By adjusting the installation position of the shovel teeth 22, the spacing between the shovel teeth 22 can be adjusted to adapt to the planting spacing of different varieties of radishes.

[0041] As Figure 1 , Figure 2 and Figure 4 shown, the clamping and conveying mechanism includes a second drive assembly and two conveying assemblies 3 symmetrically distributed on the left and right. Each conveying assembly 3 includes a bracket 31, a belt 32, a driving pulley 33, a first driven pulley 34 and a gathering claw 35. The bracket 31 is inclined on the vehicle frame 11 with the front end lower than the rear end. A gathering claw 35 is provided at the front end of the bracket 31. A driving pulley 33 and a driven pulley are rotatably arranged on the bracket 31. The belt 32 is wound around the driving pulley 33 and the driven pulley.

[0042] The belts 32 of the two conveying components 3 are spaced apart to form a clamping groove 36. The second driving component is connected to the driving pulleys 33 of the two conveying components 3, and the second driving component is used to drive the belts 32 of the two conveying components 3 to rotate in opposite directions.

[0043] Among them, the second driving component includes a second motor 37, a driving bevel gear 38, a driven bevel gear 39, a driving gear 310 and a driven gear 311. The driving gear 310 is coaxially and fixedly connected to the driving pulley 33 of one of the conveying components 3, and the driven gear 311 is coaxially and fixedly connected to the driving pulley 33 of the other conveying component 3. The driving gear 310 meshes with the driven gear 311. The driving gear 310 is coaxially and fixedly connected to the driven bevel gear 39. The second motor 37 is connected to the driving bevel gear 38, and the driving bevel gear 38 meshes with the driven bevel gear 39.

[0044] Thus, the second motor 37 can drive the two driving pulleys 33 to rotate synchronously and in opposite directions through the transmission of the driving bevel gear 38, the driven bevel gear 39, the driving gear 310 and the driven gear 311, and further drive the belts 32 of the two conveying components 3 to rotate in opposite directions.

[0045] During operation, after the soil loosening mechanism 2 loosens the soil, the leaf gathering claws 35 gather the radish leaf segments. As the leaf segments are gathered, the conveyor belts of the two conveying components 3 tightly clamp the radish leaf tassels and convey them backward. Since most of the soil on both sides of the radish root has been loosened at this time, it is very easy to pull out the radish.

[0046] Furthermore, in order to improve the harvesting efficiency, there are multiple clamping and conveying mechanisms in this device, which are arranged at intervals in the left-right direction. Figure 1 and Figure 2 There are two clamping and conveying mechanisms as shown in.

[0047] As Figure 2 and Figure 5 shown, the soil cleaning mechanism 4 includes two brushes 41 respectively installed on the brackets 31 of the two conveying components 3. The two brushes 41 are symmetrically distributed on the left and right sides of the clamping groove 36. A second driven pulley 42 is fixedly provided at the top of each brush 41. The second driven pulley 42 is rotatably installed on the corresponding bracket 31 and is driven to rotate by the belt 32 on this bracket 31.

[0048] As Figure 2 and Figure 6 shown, the root-leaf separation mechanism 5 includes two blades 51 respectively installed on the brackets 31 of the two conveying components 3. The two blades 51 are symmetrically distributed on the left and right sides of the clamping groove 36. A third driven pulley 52 is fixedly provided at the top of each blade 51. The third driven pulley 52 is rotatably installed on the corresponding bracket 31 and is driven to rotate by the belt 32 on this bracket 31.

[0049] Thus, when the belt 32 rotates, it can automatically drive the second driven pulley 42 and the third driven pulley 52 to rotate, and further drive the brush 41 and the blade 51 to rotate. When the two brushes 41 rotate, the soil can be peeled off from the radish to avoid damaging the radish. When the two blades 51 rotate, the radish stems and leaves can be quickly cut off to complete the separation. In this structural form, the linkage of the belt 32, the brush 41 and the blade 51 can be realized, and there is no need to set up an additional driving mechanism to drive the brush 41 and the blade 51 to rotate separately, so that the overall structure of the device will be more simple and compact.

[0050] As Figure 1 and Figure 2 shown, the collection mechanism 6 includes a radish root collection box 61 and a stem and leaf collection box 62. The radish root collection box 61 and the stem and leaf collection box 62 are both arranged on the vehicle frame 11. The radish root collection box 61 is located below the blade 51 and is used to collect the separated radishes. The stem and leaf collection box 62 is located below the end of the clamping groove 36 and is used to collect the separated stems and leaves.

[0051] Furthermore, the bottom of the radish root collection box 61 is inclined, for example, it can be lower in the front and higher in the rear, so that the radishes can be stacked forward, preventing the problem that the collection box overflows on one side and remains on the other side due to the radishes piling up on one side. The collection mechanism 6 also includes a spare collection box 63, and the spare collection box 63 is arranged behind the stem and leaf collection box 62 for quick replacement after the collection box is full.

[0052] Further, there is an opening on one side of the vehicle frame 11, which is convenient for directly taking out the radish root collection box 61 from the side platform after it is full, making it more convenient and fast.

[0053] To sum up, the device integrates soil loosening, conveying, soil cleaning, root and leaf separation and classification collection, and can complete the automatic harvesting of radishes at one time, thus reducing the labor cost. In addition, the device uses two symmetrically arranged belts 32 to clamp and convey the radishes by reverse rotation. When the belt 32 rotates, it can also drive the brush 41 and the blade 51 to rotate, realizing the linkage of the belt 32, the brush 41 and the blade 51. There is no need to set up an additional driving mechanism to drive the brush 41 and the blade 51 to rotate separately, making the overall structure of the device more simple and compact, simplifying the overall driving structure form and reducing the driving cost.

[0054] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
