Description

Technical Field

[0001] The utility model relates to the technical field of tillage devices, in particular to a tillage device. Background Art

[0002] A harrow is a tillage device, mainly used for land preparation, loosening soil and removing residual plant materials, which helps soil ventilation and water infiltration. It is often used in vegetable fields. The worker holds the harrow handle and performs land operations through the harrow head, and needs to bend over for a long time during the work.

[0003] A Chinese patent discloses an agricultural iron rake (authorization announcement number CN206775938U). This patented technology includes a mounting rod and a connecting rod. The left side of the mounting rod has a receiving slot. The left end of the connecting rod is fixedly connected to the rake body. The right end of the connecting rod extends into the interior of the receiving slot. The top of the connecting rod, located inside one end of the receiving slot, has a clamping slot. The top of the mounting rod is fixedly connected to a bearing. The top of the bearing is movably connected to a screw. The top of the screw is fixedly connected to a turntable. The surface of the screw is threadedly connected to a threaded sleeve. The left side of the threaded sleeve is fixedly connected to a lifting rod. The utility model achieves the effect of adjusting the length of the iron rake through the coordination of the mounting rod, connecting rod, receiving slot, clamping slot, screw, threaded sleeve, fixed block, clamping rod, connecting block, and groove. The user can turn the soil in the area where it needs to be turned without stepping on the growing crops, making it easy to use.

[0004] This patented technology can effectively adjust the length of use during use, but there are still some shortcomings during use. During the work process, it is necessary to bend over for a long time, which makes the spine and muscles in a tense state for a long time, increases the burden on the waist, back, neck and other parts, easily causes fatigue, and the comfort level during use is low. Therefore, those skilled in the art provide a tillage device to solve the problems raised in the above background technology. Utility Model Content

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] See also Figure 1-Figure 5 As shown, this embodiment is a tillage device, comprising:

[0042] The traveling trolley 100 includes a support tube 101, a travel cylinder 102 slidably mounted inside the two ends of the support tube 101, mounting seats 103 located at both ends of the travel cylinder 102, and rollers 104 rotatably mounted inside the mounting seats 103 and symmetrically distributed;

[0043] The mobile structure 300 includes a guide rail 303, a slider 304 slidably mounted on the outer wall of the guide rail 303, a rotating shaft 1 302 rotatably mounted inside the upper end of the slider 304, a rotating base 301 fixed to the upper end of the rotating shaft 1 302, a sleeve 306 located inside the rotating base 301, a rotating shaft 2 307 rotatably mounted at both ends of the sleeve 306 and fixedly connected to the inner wall of the rotating base 301, a rake rod 309 slidably inserted into the sleeve 306, and a rake head 308 located at one end of the rake rod 309.

[0044] A handle 105 is provided at the front end of the traveling trolley 100;

[0045] Multiple groups of balls 305 distributed in a circular array are rotatably mounted on the inner wall of the sleeve 306;

[0046] Use of the walking trolley 100 and the mobile structure 300;

[0047] The rake rod 309 is slidably inserted into the sleeve 306 when in use, and is slidably supported by the ball bearing 305, and is longitudinally rotated by the second shaft 307, supported by the rotating seat 301, and rotated left and right by the first shaft 302, and slides horizontally on the guide rail 303 by the slider 304, so that the handle head 308 can be adjusted to multiple angles and positions by grasping the rake rod 309. When in use, the rake rod 309 is effectively supported, and the angle and height of the rake head 308 are adjustable. When tilling the land in the vegetable field, after tilling an area of land is completed, the handle 105 is grasped and pulled to pull the support tube 101. The pulling force is applied to the roller 104 to realize mobile support of the rake and change the tillage area. During use, bending over for a long time will make the operator feel tired and uncomfortable, affecting the comfort of the worker. The spine and muscles are in a tense state for a long time, which increases the burden on the waist, back, neck and other parts, which is easy to cause fatigue, soreness or injury of the waist and back, thereby improving the comfort of the worker.

[0048] Example 2

[0049] See also Figure 1-Figure 5 As shown, this embodiment is based on embodiment 1 and also includes:

[0050] as well as;

[0051] The adjustment structure 200 includes a support tube 207 fixed to the lower end of the guide rail 303 , and a support plate 208 slidably inserted into the support tube 207 and having its lower end connected to the upper end of the support tube 101 .

[0052] A sliding sleeve 204 is embedded in the support tube 101. The upper end of the travel cylinder 102 is provided with equidistantly distributed sockets 206. The sliding sleeve 204 is slidably connected with a plug rod 205 corresponding to the socket 206.

[0053] A limit ring 202 is provided at the upper end of the insertion rod 205. A spring 203 is provided between the limit ring 202 and the support tube 101 and is sleeved on the outer side of the insertion rod 205. A pull ring 201 is provided at the upper end of the limit ring.

[0054] The support plate 208 is provided with equally spaced second jacks 209, and the support tube 207 is provided with symmetrically distributed travel holes 212. The travel holes 212 are slidably connected to the second jacks 209. The second rods 211 corresponding to the second jacks 209 are provided in the travel holes 212. A second limit ring 210 is provided at one end of the second rod 211. A pull handle 213 fixedly connected to the second rod 211 is provided on one side of the second limit ring 210. A second spring 214 is provided between the second limit ring 210 and the support tube 207 and is sleeved on the outside of the second rod 211.

[0055] Performing the use of the adjustment structure 200;

[0056] During use, the support tube 207 slides on the outer wall of the support plate 208 to adjust the height of the sleeve 306, so as to avoid the user having different heights and being unable to adjust the rake rod 309 to the appropriate height during use. The adjusted support tube 207 is inserted into the corresponding second insertion hole 209 through the second insertion rod 211, and the second insertion rod 211 is elastically supported by the second spring 214, thereby achieving the fixation of the adjusted support tube 207;

[0057] When cultivating the vegetable field, the width of the single area is different. The support cylinder 207 can slide inside the support tube 101 to adjust the width of the roller 104. When necessary, the roller 104 can be prevented from rolling directly on the vegetable field. The stroke cylinder 102 after the position is adjusted is inserted into the socket 206 through the elastically supported insertion rod 205, and then the adjusted stroke cylinder 102 is clamped and positioned to maintain the stability of the stroke cylinder 102, thereby improving the flexibility of the equipment during use.
