Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a device and method for lifting grapevines by alternating double shovels into the soil. Background Technology

[0002] Because grape cultivation in northern regions primarily uses an open-field trellis system, the cold, dry winter climate easily causes wind damage and frost damage to the vines. Therefore, before winter, the vines need to be pruned of side branches and removed from the trellis, laid out along the rows on the ground, and covered with soil for winter protection. In the following spring, when temperatures warm up, the soil covering the vines is removed before they are put back on the trellis. Removing the vines too early can cause frost damage, while removing them too late can cause them to sprout in the soil, which is easily damaged during the removal process. Therefore, the vines should be put back on the trellis about one week after the weather warms up and before the vines sprout. The traditional method for removing grapevines in spring is to use manual labor with shovels or machines (using impellers or brushes) to remove the soil covering the vines before placing them on the trellis. During the clearing and vine-lifting process, the grapevines are always buried in the soil, making their location impossible to discern visually. This makes it extremely easy to damage the vine's surface during manual or mechanical clearing. Therefore, traditional methods of grapevine lifting suffer from high labor intensity, time constraints, low efficiency, and high labor costs. Researching mechanized methods for spring grapevine lifting is therefore of great significance for promoting the development of the grape industry and increasing growers' income. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a double-shovel alternating vine-lifting device for grapevines. This device has a simple structure and is easy to operate. The depth of penetration, vine-lifting height, and lifting force can be adjusted according to soil conditions and vine age, increasing the device's applicability. This vine-lifting device effectively alleviates the problems of high labor intensity, low efficiency, high cost, and time-sensitive nature of manual vine lifting in spring, thus improving the mechanization level of grape cultivation management.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A grapevine vine-lifting device with alternating double shovels, comprising a main frame and a secondary frame movably connected to each other, characterized in that it further comprises a transmission mechanism mounted on the main frame and a vine-lifting mechanism mounted on the secondary frame; the transmission mechanism and the vine-lifting mechanism are interconnected.

[0006] The transmission mechanism is used to transmit power to the rattan-raising mechanism;

[0007] The vine-lifting mechanism includes two digging shovels VI, which are driven by a transmission mechanism to alternately enter the soil, lifting the grapevines out of the soil so that the vines that are about to sprout are exposed.

[0008] Based on the above plan,

[0009] The transmission mechanism includes a speed reducer 10, which is fixedly mounted on the main frame. The input shaft of the speed reducer 10 is connected to the input shaft 6 via a sprocket and a chain, and the input shaft 6 is connected to a power source. A torque limiter 12 is fixed on an intermediate shaft 13, and the output shaft of the speed reducer 10 is connected to the torque limiter 12 via a sprocket and a chain.

The input shaft 6 and the intermediate shaft 13 are mounted on the main frame via bearings, and the intermediate shaft 13 is connected to the rattan lifting mechanism via a sprocket and a chain.

[0010] Based on the above plan,

[0011] The vine-lifting mechanism also includes two sets of digging shovel transmission mechanisms, both of which are connected to the sub-frame; each set of digging shovel transmission mechanisms is movably connected to a digging shovel part VI and drives the corresponding digging shovel part VI to perform the vine-lifting operation.

One end of each of the two crank parts IV of the two sets of digging shovel transmission mechanisms is fixedly installed at both ends of the sprocket shaft 41. The two crank parts IV are parallel to each other in opposite directions relative to the sprocket shaft 41. The sprocket shaft 41 is mounted on the sub-frame through bearings. The sprocket shaft 41 is connected to the intermediate shaft 13 through a sprocket and a chain.

[0013] Each digging shovel transmission mechanism also includes a rocker arm part II, a rocker arm part III, and an adjusting spring part V: one end of the rocker arm part II is movably connected to the other end of the crank part IV via a bearing; one end of the rocker arm part III is movably connected to the sub-frame via a bearing; the other end of the rocker arm part III is movably connected to the middle of the rocker arm part II via a bearing; one end of the adjusting spring part V is hinged to the rocker arm part II; and the other end of the adjusting spring part V is movably connected to the digging shovel part VI.

[0014] Based on the above plan,

[0015] The rocker arm part II includes a wall panel 25; the wall panel 25 has multiple position adjustment holes in the middle, which are used to be hinged to one end of the adjustment spring part V. The soil entry angle of the digging shovel part VI can be adjusted by selecting the connection between the adjustment spring part V and different position adjustment holes.

[0016] Based on the above plan,

[0017] The rocker arm part III includes a rocker arm plate 31; one end of the rocker arm plate 31 is provided with a rocker arm shaft 28, which is used to be movably connected to the middle of the rocker arm part II through a bearing; the other end of the rocker arm shaft 28 is provided with a bearing, which is used to be movably connected to the front shaft 22 provided on the sub-frame.

[0018] Based on the above plan,

[0019] The crank section IV includes a crank main tube 32; one end of the crank main tube 32 is provided with a crank shaft 33, which is used to be movably connected to one end of the rocker arm section II via a bearing; the other end of the crank main tube 32 is provided with a crank hub 34, which is used to be fixedly connected to the sprocket shaft 41.

[0020] Based on the above plan,

[0021] The adjusting spring part V includes a spring frame 38; one end of the spring frame 38 is provided with a hook, which is used to hinge with the position adjustment hole on the rocker arm part II; a spring rod 35 is provided inside the spring frame 38, one end of the spring rod 35 extends out of the other end of the spring frame 38 and is hinged to the digging shovel part VI; a spring 36 is wound on the spring rod 35, one end of the spring 36 is fixedly connected to the other end of the spring rod 35, and the other end of the spring 36 is fixedly connected to the spring frame 38.

[0022] Based on the above plan,

[0023] The digging shovel part VI includes a column 40, and a digging shovel 39 is fixedly installed at one end of the column 40; the other end of the column 40 is hinged to one end of the spring rod 35 that extends out of the spring frame 38; the middle part of the column 40 is hinged to the other end of the rocker arm part II.

[0024] Based on the above plan,

[0025] The main frame is equipped with a depth-limiting ground wheel 4 that can adjust the height of the main frame off the ground and a three-point mounting bracket 3, which is used to connect with the tractor.

[0026] The main frame is equipped with a hydraulic cylinder seat I 46, and the auxiliary frame is equipped with a hydraulic cylinder seat II 21. The two ends of the hydraulic cylinder 43 are respectively hinged to the hydraulic cylinder seat I 46 and the hydraulic cylinder seat II 21. The main frame and the auxiliary frame are hinged together by a pin 44. The extension and retraction of the hydraulic cylinder 43 is used to adjust the rotation angle of the auxiliary frame around the pin 44, so as to control the expansion and retraction of the auxiliary frame relative to the main frame.

[0027] Both the main frame and the sub-frame are provided with limiting holes. During operation, the positioning pin 45 passes through the limiting holes on the main frame and the sub-frame to position the sub-frame.

[0028] Another objective of this invention is to provide a method for lifting grapevines by alternating the use of two shovels. This method involves lifting the grapevines to the soil ridge and then trellising them. This method not only effectively avoids damage to the grapevines during the soil clearing process, but also allows the grapevines to be trellised in a short time before subsequent soil clearing, thus allowing more time for soil clearing without delaying the farming season.

[0029] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0030] Step 1: Attach the rattan lifting device to the tractor and connect the tractor's PTO output shaft to the input shaft 6; adjust the hydraulic cylinder 43 to open the subframe, and insert the positioning pin 45 into the limiting hole on the main frame and the limiting hole on the subframe to position the subframe; adjust the depth-limiting ground wheel 4 to the appropriate working height.

[0031] Step 2: Adjust the assembly position of the position adjustment hole on the rocker arm part II and the adjustment spring part V so that the digging shovel 39 reaches a suitable soil penetration depth; adjust the adjustment spring part V so that the spring 36 is at a suitable preload.

[0032] Step 3: Start the PTO output of the tractor, so that the digging shovels 39 in the two digging shovel sections VI, driven by the swing arm section II, alternately perform the actions of digging into the soil and picking up the vines along a specific trajectory, thereby picking up the grapevines from the soil ridge.

[0033] Step 4: Once the operation is complete, pull out the positioning pin 45 and adjust the hydraulic cylinder 43 to rotate the auxiliary frame relative to the main frame to a certain position for changing or transporting.

[0034] The beneficial effects of the grapevine digging device and method described in this invention, which involves alternating double shovel insertion into the soil, are as follows:

[0035] (1) The method of lifting the vines is practical and effective. After the grapevines are lifted out of the soil ridges, the vines are exposed, and the soil can be cleared from the vines during the clearing operation. Compared with the traditional method of clearing the soil before trellising, this method can effectively avoid damage to the grapevines during the clearing process;

[0036] (2) The method of lifting the vines allows for more time for clearing the soil. After the grapevines are lifted out of the soil ridges, they are placed on the trellis first. This allows the grapevines to be placed on the trellis in a short time, and the soil clearing work can be carried out later. This allows for more time for soil clearing work without delaying the farming season.

[0037] (3) The vine-lifting device has a simple structure, which solves the problem of mechanized operation of vine lifting in spring and improves the mechanization level of grape vine production management.

[0038] (4) The vine-lifting device can adjust the height of the depth-limiting ground wheel, thereby adjusting the digging depth of the digging shovel, thus adapting to the vine-lifting operation of trench-planted or ridge-planted grapes, improving the practicality and applicability of the vine-lifting device;

[0039] (5) The lifting force of the vine-lifting device's shovel can be adjusted by adjusting the spring compression and the position of the adjustment hole;

[0040] (6) The key components of the rattan lifting device's subframe are detachable, facilitating the replacement and maintenance of related parts;

[0041] (7) The rattan lifting device uses a torque limiter, which can protect the reducer from overload during the rattan lifting operation; Attached Figure Description

[0104] Step 3: After the grapevines are trellised, remove the protective soil around the base of the grapevines manually or by machine.

[0105] The general working process of this invention is as follows: Before operation, the tractor is connected to the device via a three-point suspension; the hydraulic output port is connected to the hydraulic cylinder 43; the drive shaft is engaged so that the tractor's PTO output shaft is connected to the input shaft 6 of this device; the depth-limiting ground wheel 4 is adjusted to a suitable working height; by adjusting the position adjustment hole on the rocker arm part II and the assembly position of the adjusting spring part V, the digging shovel 39 reaches a suitable soil penetration depth; the hydraulic cylinder 43 is put into a retracted state, and the sub-frame is fixed by using the positioning pin 45 through the positioning plate 15; the nut on the spring rod 35 of the adjusting spring part V is adjusted so that the spring 36 reaches a suitable preload. During operation, position the tractor between rows with the soil ridge on the right side of the implement. Start the tractor's PTO output. The rotational power transmission route of the tractor's PTO output is: input shaft 6 - input sprocket 8 - reducer input sprocket 9 - reducer 10 - reducer output sprocket 11 - torque limiter 12 - intermediate shaft 13 - sprocket 42 - sprocket shaft 41. Driven by the sprocket shaft, the rocker arm II swings rhythmically, driving the digging shovel VI to move. As the tractor moves forward, the tip of the digging shovel 39, driven by the rocker arm II, performs a specific trajectory for soil insertion and vine removal: the digging shovel 39 inserts into the soil below the grapevine along the specific trajectory, then lifts it upwards, removing the grapevine from the soil ridge. After the operation is completed, when changing rows and transporting the vine, pull out the positioning pin 45 on the positioning plate 15, and open the tractor's hydraulic power output, causing the hydraulic cylinder 43 to extend. Under the action of the hydraulic cylinder, the subframe rotates counterclockwise along the pin shaft 44 to a certain position before changing rows and transporting the vine.
