Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery devices, and relates to an offset grapevine down-lowering and fixing device in the northern soil-burying cold protection area. Background Art

[0002] In the grape planting industry, the winter management of grapevines is a crucial work link. Lowering the grapevines in winter and fixing them to the ground can not only effectively protect the grapevines from low-temperature freezing damage, but also ensure good growth of the grapevines in the coming year, which plays a key role in improving the grape yield and quality.

[0003] Currently, in the process of grape planting, the down-lowering and fixing operations of grapevines mainly rely on manual labor. When manually lowering grapevines, workers need to carefully untie each grapevine from the wire one by one. This process requires workers to have rich experience to avoid damaging the grapevines. However, the manual operation efficiency is extremely low. A skilled worker can at most complete the down-lowering work of 0.5 to 1 mu of vineyards per day. In the scenario of large-scale vineyard planting, the manual down-lowering operation takes a long time. Especially in winter when time is tight, it may lead to freezing damage to the grapevines due to the inability to complete the down-lowering work in time, affecting the grape harvest in the following year.

[0004] For the fixing link of grapevines, the traditional method is that workers use ropes or simple fixing tools to tie and fix the down-lowered grapevines to the ground. This method is not only cumbersome in operation, but also the fixing effects are uneven. The rope tying is easy to loosen. In case of bad weather such as strong winds, the grapevines are easily blown up and lose their protection effect. Moreover, the manual fixing consumes a large amount of labor costs. According to statistics, in a 50-mu vineyard, for the work of only fixing grapevines, if all rely on manual labor and calculate according to each person fixing 0.3 mu per day, about 167 person-times need to be hired, and the labor cost expenditure is huge.

[0005] Currently, there is no grapevine down-lowering machine in production, and still manual labor is used to lower the grapevines and then tie them up. Summary of the Invention

[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide an offset grapevine down-lowering and fixing device in the northern soil-burying cold protection area, and solve the technical problems of high manual dependence, low efficiency, and easy damage to grapevines existing in the process of down-lowering and fixing grapevines in the background art.

[0076] The tractor is: 70 horsepower tractor.

[0077] The working process of the offset grapevine lowering and fixing device for the northern buried cold protection zone of the present invention is as follows:

[0078] Before removing the grape vines from the rack and fixing them, the driver first adjusts the telescopic cylinder 501 according to the row spacing of the grape vine rack so that the sliding rod 504 and the support rod 506 move to appropriate positions, and the vine-pushing mechanism 2 and the vine-pressing and fixing mechanism 3 installed on the support rod 506 are also located in appropriate working positions as the support rod 506 moves; then the pitch angle adjustment threaded rod 215 is adjusted according to the specific growth of the grape vines so that the vine-pushing mechanism 2 is located at an appropriate pitch angle.

[0079] The supporting hollow shaft 201 is connected to the bearing seat 405 through a rotating pair to support the entire vine-pulling mechanism 2. After the tractor is started, the power output by the PTO is first transmitted to the first reducer 401 and then to the slidable coupling 404 through a key connection. The slidable coupling 404 transmits the power to the reversing reducer 202. The reversing reducer 202 provides power to the primary pulley 204 through the power intermediate transmission shaft 211. The primary pulley 204 transmits the power to the secondary pulley 205 through a belt transmission. The secondary pulley 205 drives the paddle wheel rotating shaft 206 through a key connection. Finally, the paddle wheel rotating shaft 206 drives the paddle wheel 207 to rotate; the paddle wheel 207 rotates to lift the grapevines leaning on the wire upwards. The blades on the paddle wheel 207 have a certain arc shape that can hook the grapevines as the paddle wheel 207 rotates. At the same time, a spring is installed inside the paddle wheel 207 to prevent the grapevines from being damaged due to excessive torque of the paddle wheel 207. When the grape vine rotates with the dial wheel 207, the grape vine will continue to rotate with the dial wheel due to inertia. A lower vine member 210 is added to the vine-moving mechanism 2. When the grape vine rotates to the position of the lower vine member 210, the lower vine member 210 will forcibly block the grape vine from the dial wheel 207.

[0080] After the tractor is started, 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. Thereafter, the power is transmitted to the third reducer 406 by the slidable coupling 404. The power of the third reducer 406 is then transmitted to the pulley shaft 410 by the universal coupling 407 through a key connection. The rotation of the pulley shaft 410 drives the active pulley 409 installed thereon. The active pulley 409 transmits the power to the crank drive pulley 308 through a belt. The rotation of the crank drive pulley 308 provides power for the crank slider unit composed of the crank 309, the connecting rod 310 and the sliding push head 311, thereby realizing the up and down reciprocating motion of the sliding push head 311.

[0081] As the tractor moves forward as a whole, the grapevines pushed onto the ground by the vine-pushing mechanism 2 will be pre-compressed by the pressing wheel 304. The pressing force of the pressing wheel 304 can be adjusted by the contour structure 303. The pressing wheel 304 adopts an "eight"-shaped structure, which compresses the grapevines to a certain extent and gathers the grapevines toward the middle of the pressing wheel 304.
