The two support arms 15 in each group of support arms 15 are connected together by means of the connecting frame 14, and the connecting frame 14 is "U"-shaped.

[0026] In this embodiment, the garlic brushing mechanism 2 includes a supporting side plate 20, a brush plate 21, bristles 22, a slider 23, a connecting block 24 and a reciprocating mechanism 25. The supporting side plates 20 have two and are symmetrically arranged.

[0027] The reciprocating mechanism 25 includes a support frame 250 and a swing arm 251. The support frame 250 is in the shape of an I. Both ends of the support frame 250 are respectively installed and fixed on the lower ends of the two supporting side plates 20. The geometric center of the swing arm 251 is rotatably connected to the rotating shaft 253 on the support frame 250 by means of a bearing. The lower ends of the two connecting blocks 24 are connected with a connecting column 254. Both ends of the swing arm 251 are provided with a long hole 252 that matches the connecting column 254.

[0028] In this embodiment, the garlic-cracking mechanism 3 includes a roller shaft 30, blades 31 and an input sprocket 32. A plurality of blades 31 are circumferentially fixed on the outer circumference of the roller shaft 30. The input sprocket 32 ​​is coaxially arranged on one side of the roller shaft 30 and is used to connect with an input power source to realize the operation of the garlic-cracking mechanism 3.

[0029] The driving mechanism 4 includes a turntable 40 and a connecting rod 41. The turntable 40 is coaxially arranged on one side of the input sprocket 32. A connecting column 2 42 is arranged at an eccentric position on the end face of the turntable 40. A connecting column 3 43 is arranged on the connecting block 24. Both ends of the connecting rod 41 are rotatably connected to the connecting column 2 42 and the connecting column 3 43 respectively.

[0030] In this embodiment, a mud guard 5 is fixed on the supporting side plate 20 between the roller shaft 30 and the brush plate 21, which is used to prevent the mud generated in the garlic brushing mechanism 2 from being thrown onto the blades 31 in the garlic knocking mechanism 3 and causing adverse effects. A scraping mechanism 6 that cooperates with the connecting rod 41 is provided on the mud guard 5.

[0031] Specifically, the scraping mechanism 6 includes a scraper 60, a guide block 61, a guide hole 62, a back plate 1 63, a back plate 2 64 and a return spring 65. The cross-sectional shape of the mudguard 5 is a triangle. The mudguard 5 is provided with at least two guide holes 62. The scraper 60 is slidably connected to the mudguard 5 by means of a guide block 61 located in the guide hole 62. The other end of the guide block 61 is connected to the back plate 1 63. The back plate 2 64 is installed at the lower end of the mudguard 5. The return spring 65 is arranged between the back plate 1 63 and the back plate 2 64.

Both ends of the scraper 60 extend to the outside of the supporting side plate 20.

[0032] The working process of the present invention is as follows:

[0033] During the operation of the garlic clamping mechanism 1, the conveying belt 13 rotates and continuously conveys the harvested garlic 7 from a low point to a high point (that is, from the front end to the rear end of the garlic clamping mechanism 1). During this process, the blades 31 continuously rotate and strike the garlic heads, causing the larger block soil on the garlic heads to fall off first, and then the garlic heads enter the garlic brushing mechanism 2. Due to the synchronous rotation of the turntable 40 and the blades 31, it will drive the brush plate 21 to move back and forth in the conveying direction of the garlic heads with the help of the connecting rod 41, producing an action similar to rubbing clothes, further cleaning the soil on the garlic heads, so as to achieve the effect of further cleaning the soil, until the garlic 7 moves out of the area where the garlic brushing mechanism 2 is located, completing the entire cleaning process.

[0034] As the connecting rod 41 continuously moves downward, it pushes the scraper 60 to move downward along the fender 5 to scrape off the mud on the fender 5 to prevent accumulation, and when the connecting rod 41 rises, the scraper 60 is reset by the reset spring 65 to prepare for the next scraping process.

[0035] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
