Description

Technical Field

[0001] The utility model relates to the field of agricultural harvesting, in particular to a Chinese cabbage pulling and root cutting device. Background Art

[0002] Chinese cabbage is a veritable gem among vegetables. It not only boasts strong adaptability, high yield, and excellent taste, but also drives the development of related industries such as transportation, processing, and sales. Chinese cabbage is rich in nutrients such as vitamin C, vitamin K, and fiber, which are beneficial to human health. Consequently, Chinese cabbage cultivation and demand have remained high. However, traditional cabbage harvesting relies on manual labor, but labor costs are rising. Manual harvesting is inefficient and susceptible to human factors, such as variability in harvesting techniques. Therefore, the design of a cabbage rooting and cutting device is particularly important. Such a device can effectively pull up and cut the roots of cultivated cabbage, reducing farmers' labor intensity and improving cabbage harvesting efficiency.

[0003] Most existing cabbage rooting and cutting devices are roller chain-driven harvesting devices. These utilize a roller chain drive coupled with a belt drive to collect the vegetables. The drive belt is positioned at an angle, with drive sprockets on either side and a serrated blade mounted at the bottom for cutting. During the rooting operation, the device is placed in front of the cabbage. The operator uses the blades at the front to horizontally cut the cabbage protruding from the soil, which is then collected by the belt. However, these roller chain-driven devices cannot cut below the soil at the root of the cabbage, nor can they adjust the feed depth. Furthermore, they are difficult to turn, making them unsuitable for cutting cabbage from the root and for switching between different cutting paths. Utility Model Content

[0034] The motor 9 is secured to the fourth positioning plate 18 via a first motor fixing bolt 49, a second motor fixing bolt 50, a third motor fixing bolt 51, and a fourth motor fixing bolt 52. The rotating shaft of the motor 9 is movably connected to the fourth positioning plate 18 via a first bearing 45. The rotating shaft of the motor 9 is connected to a first rotating shaft 46, which is fixedly connected to a first pulley 10. The first pulley 10 is connected to a second pulley 12 via a belt 11. The second pulley 12 is mounted on a second rotating shaft 36, which is movably connected to the fourth positioning plate 18 via a bearing. A blade 14 is provided at the other end of the second rotating shaft 36. The motor 9 is connected to a motor control board, which is connected to an external power supply or battery.

[0035] The machine base mainly includes: a tire 8, a second positioning plate 4, a third positioning plate 7 and a lifting frame 5.

[0036] The upper end of the pulling frame 5 is welded to the second positioning plate 4; the third positioning plate 7 is fixed to the pulling frame 5 by the first fixing bolt 41 of the third positioning plate and the second fixing bolt 42 of the third positioning plate; two extension plates are fixed on the pulling frame 5, and the spacing between the extension plates is smaller than the diameter of the cabbage and larger than the diameter of the root of the cabbage, so that the cabbage can be easily pulled up and the root of the cabbage is under the blade.

[0037] The tire 8 is connected to the first wheel frame 37 and the second wheel frame 38 respectively through the first wheel locating bolt 34 and the second wheel locating bolt 40. The upper ends of the first wheel frame 37 and the second wheel frame 38 are connected to the lifting frame 5 respectively through the first wheel frame locating bolt 33 and the second wheel frame locating bolt 39.

The vertical plate 6 is provided to facilitate the Chinese cabbage root pulling and cutting device to stand on the ground without hitting the first pulley 10.

[0039] Here's how it works:

[0040] To use the device, the cabbage rooting and cutting device is first pushed to the designated position. The motor 9 drives the first rotating shaft 46, which is then driven by the belt 11 to transmit power to the second rotating shaft 36 and the blade 14 above it. The device is then tilted forward, inserting the two extension plates on the pulling frame 5 into the soil near the roots of the cabbage. The operator then manipulates the handle 19, which drives the connecting rod 16, the fork lever 17 about the fourth positioning pin 25, and the extension of the spring 13. This causes the push rod 15 to move laterally within the fixed slider 32, connecting the blade 14 and the second rotating shaft 36 to the fourth positioning plate 18, thereby driving the blade 14 forward and deeper into the rooting operation. When the operation is complete, the handle 19 is released, and the spring 13 rebounds, driving the push rod 15 and the fourth positioning plate 18 backward, completing the rooting operation. Finally, the pulling frame 5 is withdrawn, and the cut cabbage is stored on it, completing the pulling and cutting operation.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
