Description

Technical Field

[0001] This utility model patent belongs to the technical category of agricultural machinery, and specifically discloses a cabbage clamping and root cutting device. Background Art

[0002] Cabbage, also known as Chinese cabbage and Chinese cabbage, has a history of 5,000 years. It is cold-resistant, has high yields, and has a short growth cycle. At present, my country's cabbage planting area and yield are large, and fresh cabbage matures and is harvested all year round, bringing considerable economic benefits to farmers every year.

[0003] In the current cabbage production cycle, 40% of the work is spent on harvesting. Farmers need to use tools such as short knives and short shovels to cut the cabbage from the roots, and then manually pick, arrange and pack it one by one. This production process not only consumes a lot of manpower, material and financial resources, but also has high labor intensity and very low work efficiency. It is difficult to meet the needs of large-scale production, which seriously restricts the development of vegetable cash crops. Summary of the Invention

[0004] The utility model provides a cabbage root clamping and cutting device, in order to improve the technical problems of manual harvesting of cabbage, such as low work efficiency, high labor intensity, high operation cost, difficulty in ensuring operation efficiency, and disadvantages for large-scale production.

[0005] The technical solution of this utility model patent is as follows:

[0006] The utility model provides a cabbage root cutting device, which is characterized by comprising a frame structure, a disc-shaped cabbage root cutting device, a cabbage clamping device, a cabbage conveying device and a belt transmission device.

[0007] Furthermore, the disc-shaped cabbage root cutting device includes a disc-shaped cutting mechanism and a cutting tool angle adjustment mechanism; the disc-shaped cutting mechanism is composed of two components, a disc-shaped cutting knife and a tool transmission shaft; according to the basic size of the cabbage, the disc-shaped cutting knife is installed at a height of 10 cm from the ground, and the disc-shaped cutting knife adopts an asymmetric combined cutting structure design. The two disc-shaped cutting knives maintain a certain angle, and the tool transmission shaft is installed on both sides of the frame and is driven to rotate by a DC motor of the tool transmission shaft directly powered by a battery; the cutting tool angle adjustment mechanism is composed of a handle, a screw, a bearing and a tool transmission shaft; the handle is installed at the end of the screw cantilever, the screw is connected to the frame by a transmission thread, and the bearing is connected to the slotted tool transmission shaft through point-line contact constraints in space; the handle component can be rotated manually to achieve precise adjustment of the disc-shaped cutting tool angle.

[0008] Furthermore, the cabbage clamping device is composed of two belts located above the disc-shaped cutting knife; the two belts are installed at a height of 30 cm from the ground, and based on the basic size of the cabbage, the lateral distance between the two belts is set to 20 cm; the belt transmission type is V-belt transmission, and the belt obtains power from the belt transmission device to move.

[0009] Furthermore, the cabbage conveying device is composed of a belt transmission mechanism including a tensioning mechanism, and the belt transmission mechanism including the tensioning mechanism includes a belt, a belt driving pulley, a belt driven pulley, a tensioning mechanism and a belt frame; wherein the tensioning mechanism includes a tensioning pulley, a support rod, a tension spring and a frame with a spring buckle; the belt is sleeved on the belt driving pulley, the belt driven pulley and the tensioning pulley, and the two ends of the belt driving pulley and the belt driven pulley are rotatably installed on the belt frame; the belt driving pulley is driven to rotate by the power provided by the belt transmission device; in the tensioning mechanism, a spring buckle is set every 10 cm, one end of the tension spring is connected to the spring buckle, and the other end is connected to the tensioning pulley.

[0010] Furthermore, the belt transmission device is composed of a chain transmission mechanism and a bevel gear transmission mechanism; among them, it includes 3 groups of chain transmission mechanisms and 1 group of bevel gear transmission mechanisms; the power on the diesel engine main shaft is first transmitted to the bevel gear by a vertical chain transmission, and then the bevel gear transmission is used to transmit the power to the two sprockets, and finally the upper and lower horizontal chain transmissions are used to transmit the power to the pulley shaft respectively, so as to realize the transmission of the diesel engine main shaft power to the belt transmission mechanism and save energy.

[0011] The cabbage root clamping and cutting device also includes a central control unit, and a force sensor for detecting the force of the disc cutting knife, a limit switch for determining the screw stroke, a pressure sensor and a DC motor of the tool transmission shaft are all connected to the central control unit.

[0012] The utility model patent also provides the working principle of the cabbage clamping and root cutting device, which includes the following steps:

[0013] Before the cabbage clamping and root cutting device is operated, manually rotate the handle in the cutting tool angle adjustment mechanism to adjust the left and right movement of the adjustment screw, thereby adjusting the cutting tool angle; then select a suitable spring buckle in the tensioning mechanism to ensure that the cabbage is not crushed during transportation; after adjusting the cutting tool angle and the preload of the tension spring, install the device in front of the tractor; after the tractor is started, the diesel engine main shaft rotates, driving the vertical chain drive, and then driving the bevel gear set drive, and then driving the upper and lower horizontal chain drives, and finally driving the pulley shaft to rotate, ensuring the normal operation of the belt drive mechanism in the cabbage conveying device; in conjunction with the forward speed of the tractor, when the whole machine drives in front of the cabbage, the two belts provide extrusion force to clamp the stems of the cabbage. At this time, the pressure sensor of the central control unit senses the change in belt pressure and starts the DC motor of the tool drive shaft, causing the disc-shaped cutting knife to rotate and cut the root of the cabbage until it is cut off. The force sensor detects the cutting force of the disc-shaped cutting knife in real time and feeds back the signal to the central control unit. The central control unit determines whether the root of the cabbage is cut off based on the signal of the force sensor. When the root of the cabbage is cut off, the central control unit turns off the DC motor of the tool drive shaft, and the disc-shaped cutting knife stops rotating. The cut cabbage enters the cabbage conveying device. When it passes through, the cabbage generates a force on the tension wheel, which is transmitted to the tension spring through the support rod, causing the tension spring to contract; when the cabbage plant passes, the tension spring recovers, pushing the tension wheel back to its original position, realizing smooth conveying of the cabbage.

[0014] Compared with the prior art, this utility model has the following beneficial effects.

[0015] This utility model patent proposes a cabbage root cutting device that integrates root cutting, clamping and conveying according to the basic size, planting pattern and morphological characteristics of cabbage. The central control unit is used to control the rotation of the disc-shaped cutting knife, thereby minimizing energy loss. The utility model also creatively proposes a cutting tool angle adjustment mechanism, so that the disc-shaped cutting knife adopts an asymmetric combined cutting structure design, which greatly improves the success rate of cabbage root cutting. At the same time, in the device, the cabbage clamping device and the two belts in the cabbage conveying device are consistent, so that one structure can realize two process actions, making the device structure simpler, and ultimately meeting the production requirements of cabbage with high efficiency, low loss, cost saving and profit, and improving the technical problems of high labor intensity, low work efficiency and difficulty in meeting large-scale production.
