Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a Chinese cabbage harvester. Background Technology

[0003] Chinese cabbage is a type of vegetable that is harvested without its roots. It needs to be pulled up and its roots cut off. Whether the cut is smooth, whether it is cut off-center, and whether the cabbage is damaged have a great impact on subsequent storage. During the harvesting process, existing harvesters can easily cause significant damage to the cabbage during the pulling up and cutting of its roots because the cabbages are of different sizes, which affects subsequent storage. Summary of the Invention

[0004] The purpose of this invention is to provide a Chinese cabbage harvester to solve the problems existing in the prior art, and to facilitate the low-damage harvesting and root cutting of Chinese cabbage.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides a Chinese cabbage harvester, comprising a machine body, a conveying mechanism, and a cutting mechanism. The conveying mechanism includes a conveying drive assembly, a supporting conveyor belt, two conveyor frames, two clamping conveyor belts, and two elastic support assemblies. The two conveyor frames are arranged side-by-side and fixedly connected to the machine body. The two clamping conveyor belts are rotatably mounted on the two conveyor frames, and are arranged opposite to each other to clamp the Chinese cabbage. The supporting conveyor belt is located below the two clamping conveyor belts and can support the bottom of the Chinese cabbage after the roots are cut. The conveying drive assembly is connected to the two conveyor frames and is drive-driven to the supporting conveyor belt and the two clamping conveyor belts. The two elastic support assemblies are respectively... The elastic support component is mounted on two conveyor frames and can be supported on the inner side of the clamping conveyor belt. When the clamping conveyor belt clamps the cabbage, the elastic support component can undergo adaptive elastic deformation relative to the conveyor frame so that the clamping conveyor belt can adaptively conform to the cabbage. The cutting mechanism is fixedly mounted on the lower front end of the conveying mechanism and placed at the front end of the supporting conveyor belt. It includes a cutting drive component, a clamping component, and a cutting component. The clamping component is located in front of the cutting component. The cutting drive component is driven by and can drive both the clamping component and the cutting component. The clamping component can clamp the root of the cabbage and provide an upward force. The cutting component can cut the root of the cabbage.

[0007] Preferably, the elastic support assembly includes multiple support rollers and multiple elastic elements. The multiple support rollers are distributed along the length direction of the clamping conveyor belt and on both sides of the conveyor frame, and are capable of rolling support on the two opposite inner sides of the clamping conveyor belt. The axial direction of each support roller is perpendicular to the conveying direction. Each support roller supporting the inner side of the cabbage clamping portion of the clamping conveyor belt is connected to the conveyor frame through the elastic elements. When the clamping conveyor belt clamps and squeezes the cabbage, the corresponding elastic elements can elastically deform relative to the conveyor frame and drive the support rollers to move synchronously.

[0008] Preferably, the conveying mechanism further includes a transfer conveyor belt and a tray disposed on the rear side of the clamping conveyor belt. The transfer conveyor belt and the tray are disposed on the machine body. The conveying drive assembly is connected to the transfer conveyor belt and can be driven. The tray can hold cabbage.

[0009] Preferably, the clamping assembly includes two clamping rods arranged side by side and clamping plates disposed on the two clamping rods. One end of each of the two clamping rods is connected to the cutting drive assembly. The cutting drive assembly can drive the two clamping rods to rotate so that the two clamping plates can flip up and down and clamp the root of the cabbage, and can provide an upward force to the cabbage.

[0010] Preferably, the clamping plate is made of a flexible material.

[0011] Preferably, one end of each clamping rod is connected to the cutting drive assembly via a universal joint, and the other ends of the two clamping rods are opposite each other and bent outwards.

[0012] Preferably, the cutting assembly includes two staggered cutting blades, which are tractively connected to the cutting drive assembly, which can drive the two cutting blades to rotate so as to cut the root of the cabbage.

[0013] Preferably, the machine body includes a walking device, on which a frame and a cockpit are provided, and the conveying mechanism is fixedly mounted on the frame.

[0014] Preferably, the machine body further includes a power unit disposed on the walking device, the power unit being connected to the walking device, the conveying mechanism and the cutting mechanism and capable of providing the required power.

[0015] Preferably, the machine body further includes a collection box disposed on the walking device, the collection box being used to collect cabbages.

[0016] The present invention achieves the following technical effects compared to the prior art:

[0017] The cabbage harvester provided by this invention involves the cabbage body being clamped by two clamping conveyor belts of a conveying mechanism during the harvesting process, while the root of the cabbage is clamped by a clamping component of a cutting mechanism. After the conveying drive component is activated, the clamping conveyor belts can clamp the cabbage and pull it outwards. Moreover, under the drive of the cutting drive component, the clamping component can clamp the root and provide an upward force, making it easier to pull out the cabbage, facilitating root cutting, and reducing damage to the cabbage. After the cutting component cuts off the root, the support conveyor belt can support the bottom of the cabbage to prevent it from falling. In addition, since the inner side of the clamping conveyor belt is supported by an elastic support component, when clamping the cabbage, the elastic support component can undergo adaptive elastic deformation under the reaction force of the cabbage. Thus, the clamping conveyor belt can better conform to the shape of the cabbage, thereby reducing clamping damage to the cabbage. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The purpose of this invention is to provide a Chinese cabbage harvester to solve the problems existing in the prior art, and to facilitate the low-damage harvesting and root cutting of Chinese cabbage.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This embodiment provides a Chinese cabbage harvester; please refer to [link / reference]. Figures 1-6The system includes a body 1, a conveying mechanism 2, and a cutting mechanism 3. The conveying mechanism 2 includes a conveying drive assembly 21, a supporting conveyor belt 22, two conveying frames 23, two clamping conveyor belts 24, and two elastic support assemblies 25. The two conveying frames 23 are arranged side by side and fixedly connected to the body 1. The two clamping conveyor belts 24 are rotatably mounted on the two conveying frames 23, and are arranged opposite to each other to clamp the cabbage. The supporting conveyor belt 22 is located below the two clamping conveyor belts 24 and can support the bottom of the cabbage after the root is cut. The conveying drive assembly 21 is connected to the two conveying frames 23 and is drively connected to the supporting conveyor belt 22 and the two clamping conveyor belts 24 to drive them. The two elastic support assemblies 25 are respectively mounted on the two conveying frames 23, two supporting conveyor belts 22, two clamping conveyor belts 24, and two elastic support assemblies 25. On the two conveyor frames 23, and supported on the inner side of the clamping conveyor belt 24 respectively, the elastic support component 25 can adaptively deform relative to the conveyor frame 23 when the clamping conveyor belt 24 clamps the cabbage, so that the clamping conveyor belt 24 can adaptively fit the cabbage; the cutting mechanism 3 is fixedly set on the lower front end of the conveyor mechanism 2 and placed at the front end of the supporting conveyor belt 22, including a cutting drive component 31, a clamping component 32 and a cutting component 33. The clamping component 32 is set on the front side of the cutting component 33. The cutting drive component 31 is connected to the clamping component 32 and the cutting component 33 and can drive them. The clamping component 32 can clamp the cabbage root and provide an upward force. The cutting component 33 can cut the cabbage root.

[0031] During the harvesting process, the cabbage body is held by two clamping conveyor belts 24 of the conveying mechanism 2, while the root of the cabbage is held by the clamping component 32 of the cutting mechanism 3. After the conveying drive component 21 is activated, the clamping conveyor belts 24 can clamp the cabbage and pull it outward. Moreover, under the drive of the cutting drive component 31, the clamping component 32 can clamp the root and provide an upward force, making it easier to pull out the cabbage, facilitating root cutting, and reducing damage to the cabbage. After the cutting component 33 cuts off the root, the supporting conveyor belt 22 is connected to the two conveying frames 23 through the frame and can support the bottom of the cabbage to prevent it from falling. In addition, since the inner side of the clamping conveyor belt 24 is supported by the elastic support component 25, when clamping the cabbage, the elastic support component 25 can undergo adaptive elastic deformation under the reaction force of the cabbage. In this way, the clamping conveyor belt 24 can better conform to the shape of the cabbage, thereby reducing clamping damage to the cabbage.

[0032] In the optional solutions of this embodiment, a more preferred option is described in the following description: Figure 3The elastic support assembly 25 includes multiple support rollers 251 and multiple elastic elements 252. The multiple support rollers 251 are distributed along the length of the clamping conveyor belt 24 and on both sides of the conveyor frame 23, and can roll and support the two opposite inner sides of the clamping conveyor belt 24. The rolling support method can reduce the conveying friction of the support conveyor belt 24, and the axial direction of each support roller 251 is perpendicular to the conveying direction. Each support roller 251 supporting the inner side of the clamping cabbage part of the clamping conveyor belt 24 is connected to the conveyor frame 23 through the elastic element 252. When the clamping conveyor belt 24 clamps and squeezes the cabbage, the corresponding elastic element 252 can elastically deform relative to the conveyor frame 23 and drive the support roller 251 to move synchronously. In this way, adjacent support rollers 251 can adaptively adjust their position by causing the elastic element 252 to adaptively deform when clamping the cabbage. Since the axial direction of the support rollers 251 is perpendicular to the conveying direction, the support rollers 251 can roll and support the cabbage to the conveyor frame 23. In the conveying direction, the adjacent support rollers 251, during the process of clamping the cabbage, adaptively adjust their positions to guide the cabbage so that the axis of the cabbage is as parallel as possible to the axis of the support rollers 251, so as to cut and support the root and reduce the probability of the root being cut crookedly. Specifically, the elastic element 252 includes two clamping pieces 2521 and a torsion spring 2522. Each end of the support roller 251 is rotatably connected to a clamping piece 2521. The clamping piece 2521 is rotatably connected to the conveyor frame 23 through a pin. One of the clamping pieces 2521 is also connected to the conveyor frame 23 through the torsion spring 2522. The support roller 251 rotates relative to the conveyor frame 23 through the clamping piece 2521 and can cause the torsion spring 2522 to undergo elastic deformation. The upper and lower ends of the support roller 251 clamping the inner side of the conveyor belt 24 are connected to the conveyor frame 23 through connecting pieces. The upper and lower ends of the support roller 251 are rotatably connected to the connecting pieces.

[0033] In the optional embodiment, more preferably, the conveying mechanism 2 further includes a transfer conveyor belt 26 and a tray 27 disposed on the rear side of the clamping conveyor belt 24. The transfer conveyor belt 26 and the tray 27 are disposed on the machine body 1. The conveying drive assembly 21 is connected to the transfer conveyor belt 26 and can drive it. The tray 27 can hold cabbage. The tray 27 is disposed on one side of the transfer conveyor belt 26 and can temporarily hold cabbage. The front side of the transfer conveyor belt 26 is connected to the rear side of the support conveyor belt 22 so that the cabbage can be conveyed to the transfer conveyor belt 26.

[0034] Further, please see Figure 4The conveying drive assembly 21 includes two drive rollers 211, two driven rollers 212, and a conveying shaft 213. Each conveyor frame 23 has a drive roller 211 and a driven roller 212 rotatably mounted at both ends. The drive rollers 211 and the driven rollers 212 are connected to the clamping conveyor belt 24. Both drive rollers 211 are driven by gears to the conveying shaft 213. The drive roller supporting the conveyor belt 22 is coaxially and fixedly connected to the conveying shaft 213. The conveying shaft 213 can also be connected to the drive roller of the transfer conveyor belt 26 through a transmission chain. One drive roller 211 can be driven to rotate under the action of an external motor, so as to drive the support conveyor belt 22 and the other drive roller 211 to rotate through the conveying shaft 213, thereby driving the clamping conveyor belt 24, the support conveyor belt 22, and the transfer conveyor belt 26 to move.

[0035] In the optional solutions of this embodiment, a more preferred option is described in the following description: Figure 5 The clamping assembly 32 includes two clamping rods 321 arranged side by side and clamping plates 322 disposed on the two clamping rods 321. One end of each clamping rod 321 is connected to the cutting drive assembly 31. The cutting drive assembly 31 can drive the two clamping rods 321 to rotate, so that the two clamping plates 322 can flip up and down and clamp the root of the cabbage, and can provide an upward force to the cabbage. By flipping the clamping plates 322 under the drive of the cutting drive assembly 31, different sizes of cabbage can be clamped, and the cabbage can be pulled up with assistance. During the harvesting process, the clamping rods 321 and clamping plates 322 are close to the ground in order to clamp the root of the cabbage.

[0036] In the optional solutions of this embodiment, it is more preferred that the clamping plate 322 is made of a flexible material, such as a rubber plate, which can fit and clamp tightly while avoiding contact with the cabbage body and causing greater damage; furthermore, the working surfaces of the clamping conveyor belt 24, the supporting conveyor belt 22 and the transfer conveyor belt 26 can also be made of a flexible material, such as a rubber material, to reduce damage to the cabbage.

[0037] In the optional scheme of this embodiment, it is more preferred that one end of each clamping rod 321 is connected to the cutting drive assembly 31 through a universal joint 323. The universal joint 323 can provide a certain swing range to better adapt to the clamping of cabbages of different sizes; and the other ends of the two clamping rods 321 are opposite to each other and bent outward to facilitate the guidance of the cabbage.

[0038] In the optional embodiment, more preferably, the cutting component 33 includes two staggered cutting blades 331, which are tractively connected to the cutting drive component 31. The cutting drive component 31 can drive the two cutting blades 331 to rotate so as to cut the root of the cabbage. By setting the two staggered cutting blades 331, it is convenient to cut the root.

The drive gear 312 is meshed with the two transmission gear sets 313. The cutting drive motor 311 is connected to the conveyor frame 23 through a frame. The linear universal joints 314 and the transmission gear sets 313 are rotatably connected to the mounting box 315 through bearings. The lower end of the linear universal joint 314 is meshed with the transmission gear set 313 through a bevel gear, and the upper end is fixedly connected to a cutter 331. One end of the transmission gear set 313 is connected to the clamping rod 321 through a universal joint 323. The cutting drive motor 311 rotates through the drive gear 312, which in turn drives the two transmission gear sets 313 to rotate, and then drives the clamping rod 321 and the cutter 331 on the linear universal joint 314 to rotate through the transmission gear sets 313.
