Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a cabbage harvesting device and a cabbage harvester. Background Art

[0002] A cabbage harvester is a machine for harvesting crops integrally, which can complete the work of harvesting, conveying and collecting cabbages at one time. Its main functions include improving the harvesting efficiency, reducing the labor intensity and reducing losses, etc.

[0003] For a long time, the harvesting of cabbages mainly relied on manual labor, which had problems such as high labor intensity and low efficiency. With the advancement of agricultural modernization and the reduction of rural labor force, the application demand for cabbage harvesters has gradually increased.

[0004] In the prior art, a variety of cabbage harvesters have been developed. For example, a kind of agricultural machinery equipment for harvesting cabbages disclosed in the publication number CN107172968A. The driving motor continuously works to drive the conveyor belt to move and provide output power to the transmission system to drive the cutter. During the cabbage harvesting process, the cutter continuously works and adjusts the relative distance between the two cutters according to the size of the cabbage, harvests the cabbage into the cutter and pushes it onto the belt. The belt is driven by the driving motor, supported by the roller and changes the transmission direction, and conveys the cabbage to the peeling mechanism. During the conveying process, the root of the cabbage is cut off by the cutting knife, and the cutting height can be adjusted by the cutting knife screw. The cabbage conveyed by the conveying mechanism slides downward under the guidance of the roller and contacts the peeling roller. The peeling roller continuously rotates by the power provided externally to remove the outer skin of the cabbage. Since the peeling roller is obliquely placed, the cabbages slide uniformly towards one side peeling frame during the peeling process and fall into the collection box after the peeling process ends.

[0005] Although the above-mentioned agricultural machinery equipment for harvesting cabbages is relatively simple, for farmers who plant cabbages in small quantities, if they need to purchase such equipment as a whole set, they still think the price is expensive. Content of the Utility Model

[0006] Aiming at the defects existing in the prior art, the purpose of the utility model is to provide a cabbage harvesting device and a cabbage harvester, which can solve the problem that when purchasing agricultural machinery equipment for harvesting cabbages in the prior art, it needs to be purchased as a whole set and the price is expensive.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0033] The following further elaborates on the embodiments of the present utility model with reference to the accompanying drawings.

[0034] As Figure 1 and Figure 2 shown, on the one hand, the present utility model provides a cabbage harvesting device, including: a support shaft 1, a U-shaped plow 3, a conveyor belt 4, and a transmission mechanism 5. Among them, the support shaft 1 is used to connect with the wheel hub 21 of the walking machine 2 and rotate coaxially with the wheel hub 21; the open end of the U-shaped plow 3 is rotatably connected to the support shaft 1 and is used to cut the root of the cabbage; the conveyor belt 4, one end of which is connected to the U-shaped plow 3, and the other end is used to connect to the collection box 22 to abut against the U-shaped plow 3 and convey the cabbage cut by the U-shaped plow 3 into the collection box 22; the transmission mechanism 5 connects the support shaft 1 or the driving part of the walking machine 2 with the conveyor belt 4 and is used to make the support shaft 1 or the driving part of the walking machine 2 drive the rotating shaft 41 of the conveyor belt 4 to rotate.

[0035] When using this cabbage harvesting device, connect the support shaft 1 with the wheel hub 21 of the walking machine 2, rotatably connect the open end of the U-shaped plow 3 with the support shaft 1, connect one end of the conveyor belt 4 with the U-shaped plow 3, connect the other end with the collection box 22, abut against the U-shaped plow 3, and connect the transmission mechanism 5 with the support shaft 1 or the driving part of the walking machine 2 and the conveyor belt 4. When the walking machine 2 moves forward, since the U-shaped plow 3 is rotatably connected to the support shaft 1 and is abutted by the conveyor belt 4, it will not rotate and will move forward with the walking machine 2. When encountering a cabbage, it will cut the root of the cabbage. The transmission mechanism 5 connects the support shaft 1 with the conveyor belt 4, and the support shaft 1 rotates with the wheel hub 21, so it will drive the rotating shaft 41 of the conveyor belt 4 to rotate, or the transmission mechanism 5 connects the driving part of the walking machine 2 with the conveyor belt 4 to drive the conveyor belt 4 to rotate, and will convey the cabbage cut by the U-shaped plow 3 into the collection box 22 for collection. In this way, this cabbage harvesting device can be installed on the walking machine 2, for example, installed on a walking tractor, without purchasing a complete set of cabbage harvesting equipment, saving costs.

[0036] In this example, the open end of the U-shaped plow 3 is rotatably connected to the support shaft 1 through a bearing provided on the support shaft 1. The walking machine 2 is a traveling machine with a wheel hub, such as a tractor.

[0037] The conveyor belt 4 includes a conveyor belt body and two mounting brackets. The two mounting brackets are located on both sides of the conveyor belt body. The ends of the mounting brackets are connected to the closed ends of the U-shaped plow 3. The rotating shaft 41 passes through the two mounting brackets and is rotatably connected to the two mounting brackets, so that the conveyor belt body is wound around the rotating shaft 41. There is also a driven shaft provided at one end where the mounting bracket is connected to the collection box 22 and is rotatably arranged, so that the conveyor belt is wound around the driven shaft. When the rotating shaft rotates, it can drive the conveyor belt body to rotate.

[0038] In some alternative solutions, the transmission mechanism 5 includes a first pulley 51 provided on the support shaft 1, a second pulley 52 provided on the rotating shaft 41, and a conveyor belt 53. The conveyor belt 53 is cross-wound around the first pulley 51 and the second pulley 52.

[0039] In this example, the first pulley 51 on the support shaft 1 and the second pulley 52 on the rotating shaft 41, with the conveyor belt 53 cross-wound around the first pulley 51 and the second pulley 52, can borrow the driving force on the hub 21 to drive the second pulley 52 to rotate, thereby driving the conveyor belt 4 to operate and convey the cabbages cut by the U-shaped plow 3 into the collection box 22. In addition, the conveyor belt 53 cross-wound around the first pulley 51 and the second pulley 52 can reverse the rotation direction of the hub 21 to the conveyor belt 4, so that the conveyor belt 4 can convey the cabbages after cutting the roots into the collection box 22.

[0040] In some alternative implementations, the first pulley 51 is provided outside the U-shaped plow 3, and the second pulley 52 is provided outside the conveyor belt 4.

[0041] In this example, by setting the first pulley 51 outside the U-shaped plow 3 and the second pulley 52 outside the conveyor belt 4, that is, on the side away from the walking machine 2, it is convenient to install the conveyor belt 53. In other embodiments, the first pulley 51 and the second pulley 52 can also be set inside the U-shaped plow 3 and the conveyor belt 4, which will not affect the normal use of the entire device.

[0042] In other embodiments, the transmission mechanism 5 can also be directly used to connect the rotating shaft 41 of the conveyor belt 4 to the driving part of the walking machine 2. For example, directly connecting the pulley or clutch shaft of the tractor to the rotating shaft 41 of the conveyor belt 4 through the transmission mechanism 5 can also drive the conveyor belt 4 to operate.

[0043] In some alternative embodiments, the support shaft 1 is connected to the hub 21 through a flange provided at its end.

[0044] In this embodiment, a flange is provided at the end of the support shaft 1, and bolt holes corresponding to the bolt holes on the flange are provided at the corresponding position of the wheel hub 21. In this way, the device can be directly installed on the wheel hub 21 by bolts during use.

[0045] In some alternative embodiments, the U-shaped plow 3 is provided with a protruding cutting edge on the side facing the advancing direction of the walking machine 2 for cutting the roots of cabbages.

[0046] In this embodiment, the protruding part on the side of the U-shaped plow 3 facing the advancing direction of the walking machine 2 is an arc with a smooth transition and an open cutting edge for quickly cutting the roots of cabbages.

[0047] On the other hand, the present utility model also provides a cabbage harvester, including: a walking machine 2, a support shaft 1, a U-shaped plow 3, a conveyor belt 4, and a transmission mechanism 5.

[0048] The support shaft 1 is connected to the wheel hub 21 of the walking machine 2 and rotates together with the wheel hub 21; the open end of the U-shaped plow 3 is rotatably connected to the support shaft 1 for cutting the roots of cabbages; one end of the conveyor belt 4 is connected to the U-shaped plow 3, and the other end is connected to the collection box 22 to abut against the U-shaped plow 3 and convey the cabbages cut by the U-shaped plow 3 into the collection box 22; the transmission mechanism 5 connects the support shaft 1 and the conveyor belt 4 for driving the rotating shaft 41 of the conveyor belt 4 to rotate by the support shaft 1.

[0049] When using the cabbage harvesting device, the support shaft 1 is connected to the wheel hub 21 of the walking machine 2, the open end of the U-shaped plow 3 is rotatably connected to the support shaft 1, one end of the conveyor belt 4 is connected to the U-shaped plow 3, the other end is connected to the collection box 22, and abuts against the U-shaped plow 3, and the transmission mechanism 5 connects the support shaft 1 and the conveyor belt 4. When the walking machine 2 advances, the U-shaped plow 3 will not rotate because it is rotatably connected to the support shaft 1 and is abutted by the conveyor belt 4, and will advance together with the walking machine 2. When encountering cabbages, it will cut the roots of the cabbages. The transmission mechanism 5 connects the support shaft 1 and the conveyor belt 4, and the support shaft 1 rotates together with the wheel hub 21, so it will drive the rotating shaft 41 of the conveyor belt 4 to rotate, and will convey the cabbages cut by the U-shaped plow 3 into the collection box 22 for collection. In this way, the cabbage harvesting device can be installed on the walking machine 2, for example, installed on a walking tractor, without purchasing a whole set of cabbage harvesting equipment, saving costs.

[0050] In some alternative embodiments, the walking machine 2 is a walking tractor, the support shaft 1 is connected to the wheel hub 21 of the walking tractor, and one end of the conveyor belt 4 is rotatably connected to the U-shaped plow 3, and the other end is connected to the collection box 22 of the walking tractor.

[0051] In this example, the walking machine 2 uses a walking tractor, which can save costs and can use the farm tools already available in the farmer's household, saving the farmer's purchase cost. One end of the conveyor belt 4 is rotatably connected to the U-shaped plow 3. After a whole collection box 22 of cabbages is collected, the collection box 22 can be replaced. At this time, the connection between the conveyor belt 4 and the collection box 22 can be disconnected, and the end of the conveyor belt 4 used for connecting to the collection box 22 can be lifted. Then, the connection between the walking tractor head and the collection box 22 is disconnected, and a new collection box 22 can be replaced.

[0052] In this embodiment, the handle frame 23 of the walking tractor is arranged on two transverse hole frames 24 and is equipped with a movable shaft 25 passing through the two transverse hole frames 24. The movable shaft 25 is horizontally arranged and moves horizontally to support the conveyor belt 4 when the collection box 22 is replaced.

[0053] In this embodiment, when the collection box 22 needs to be replaced or the walking tractor needs to turn, the connection between the conveyor belt 4 and the collection box 22 can be disconnected, and the end of the conveyor belt 4 used for connecting to the collection box 22 can be lifted. The movable shaft 25 horizontally arranged in the two transverse hole frames 24 is extended to support the conveyor belt 4. At this time, the conveyor belt 4 is not connected to the collection box 22, so that the walking tractor can turn, or the connection between the walking tractor head and the collection box 22 can be disconnected. Such a design can facilitate the walking tractor to turn and replace the collection box 22 after the cabbage harvester has harvested a row of cabbages.

[0054] In some alternative embodiments, one end of the conveyor belt 4 connected to the collection box 22 is provided with a quick plug-in or snap connection structure.

[0055] In this embodiment, one end of the conveyor belt 4 connected to the collection box 22 can be placed on the collection box 22, and a snap connection structure is provided at the lower part to be clamped on the collection box 22. For example, a vertical limit sleeve is provided on the collection box 22, and a limit post is provided at the lower part of the conveyor belt 4. When the conveyor belt 4 is placed on the collection box 22, the limit post provided at the lower part of the conveyor belt 4 is inserted into the vertical limit sleeve provided on the collection box 22, so that the positions of the conveyor belt 4 and the collection box 22 can be limited, and the quick disassembly and installation between the conveyor belt 4 and the collection box 22 can be realized.

[0056] In some alternative embodiments, the transmission mechanism 5 includes a first pulley 51 sleeved on the support shaft 1, a second pulley 52 sleeved on the rotating shaft 41, and a transmission belt 53. The transmission belt 53 is cross-wound around the first pulley 51 and the second pulley 52.

[0057] By the transmission belt 53 being wound around the first pulley 51 and the second pulley 52 in a crossed manner, the driving force on the hub 21 can be borrowed to drive the second pulley 52 to rotate, thereby driving the conveyor belt 4 to operate and convey the cabbages cut by the U-shaped plow 3 into the collection box 22.
