Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and specifically to an offset grapevine unloading and fixing device for frost-proofing areas in northern regions. Background Technology

[0002] In the grape growing industry, winter management of grapevines is a crucial aspect. Taking the vines down from their trellises and securing them to the ground in winter not only effectively protects them from frost damage but also ensures healthy growth the following year, playing a key role in improving grape yield and quality.

[0003] Currently, the removal and securing of grapevines during grape cultivation relies primarily on manual labor. When removing vines manually, workers must carefully untie each vine from the wires, a process requiring considerable experience to avoid damage. However, manual operation is extremely inefficient; a skilled worker can only remove vines from 0.5 to 1 acre of vineyard per day at most. In large-scale vineyard settings, manual removal is time-consuming, especially during the crucial winter months, potentially leading to frost damage and impacting the following year's grape harvest.

[0004] Traditionally, securing grapevines involves workers using ropes or simple securing tools to tie them to the ground after they've been taken down from the trellis. This method is not only cumbersome but also inconsistent in its effectiveness. Ropes are prone to loosening, and in strong winds or other inclement weather, the vines can easily be blown away, losing their protective function. Furthermore, manual securing is extremely labor-intensive. Statistics show that in a 50-acre vineyard, securing the grapevines alone, if done entirely manually, would require approximately 167 person-days, assuming each person secures 0.3 acres per day – a significant expense.

[0005] Currently, there are no machines for removing grapevines from trellises; the vines are still removed manually and then tied up. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide an offset grapevine unloading and fixing device for northern buried frost protection areas, solving the technical problems of high manual dependence, low efficiency, and easy damage to grapevines in the grapevine unloading and fixing process in the prior art.

[0076] The tractor is a 70-horsepower tractor.

[0077] The present invention relates to an offset grapevine lowering and fixing device for frost-proofing areas in northern soil-buried regions, and its working process is as follows:

[0078] Before the grapevines are untied and secured, the driver first adjusts the telescopic cylinder 501 according to the row spacing of the grapevine trellis so that the sliding rod 504 and the support rod 506 move to the appropriate position. The vine-pulling mechanism 2 and the vine-pressing and fixing mechanism 3 installed on the support rod 506 also move to the appropriate working position as the support rod 506 moves. Then, the driver adjusts the pitch angle of the threaded rod 215 according to the specific growth of the grapevines so that the vine-pulling mechanism 2 is at the appropriate pitch angle.

[0079] The hollow support shaft 201 is connected to the bearing housing 405 via a rotating pair, serving to support the entire vine-pulling mechanism 2. After the tractor starts, the power output from the PTO is first transmitted to the first reducer 401 and then transmitted to the sliding coupling 404 via a key connection. The sliding coupling 404 transmits the power to the reversing reducer 202. The reversing reducer 202 provides power to the first-stage pulley 204 via the intermediate power transmission shaft 211. The first-stage pulley 204 transmits the power to the second-stage pulley 205 via belt drive. The second-stage pulley 205 drives the pulley rotation shaft 206 via a key connection. Finally, the pulley rotation shaft 206 drives the pulley 207 to rotate. The pulley 207, by rotating, lifts the grapevines leaning against the wire upwards. The blades on the pulley 207 have a certain arc shape to hook the grapevines and make them rotate with the pulley 207. At the same time, a spring is installed inside the pulley 207 to prevent damage to the grapevines due to excessive torque of the pulley 207. As the grapevine rotates with the dial 207, the grapevine will continue to rotate with the dial due to inertia. A lower vine component 210 is added to the vine-pulling mechanism 2. When the grapevine rotates to the position of the lower vine component 210, the lower vine component 210 will forcibly stop the grapevine from the dial 207.

[0080] After the tractor starts, the power output by the PTO is first transmitted to the first reducer 401 and then to the second reducer 403 through the rigid coupling 402. After that, the power is transmitted to the third reducer 406 by the sliding coupling 404. Then, the power of the third reducer 406 is transmitted to the pulley shaft 410 by the universal coupling 407 through a key connection. The rotation of the pulley shaft 410 drives the drive pulley 409 mounted on it. The drive pulley 409 transmits the power to the crank drive pulley 308 through the belt. The rotation of the crank drive pulley 308 provides power to the crank-slider unit composed of the crank 309, connecting rod 310 and sliding pusher 311, realizing the up-and-down reciprocating motion of the sliding pusher 311.

[0081] As the tractor moves forward, the grapevines pushed to the ground by the vine-pulling mechanism 2 are pre-compressed by the press roller 304. The compressive force of the press roller 304 can be adjusted by the contour structure 303. The press roller 304 adopts an "eight"-shaped structure, which, to a certain extent, compresses the grapevines while simultaneously drawing them towards the center of the press roller 304. As the tractor continues to move forward, the sliding pusher 311 inserts the U-shaped card 312, which is placed in the U-shaped card holder 301, into the ground at a depth of about 30cm. At this point, the grapevines are fixed to the ground, completing the operation of unloading and fixing the grapevines.
