Description

Technical Field

[0001] The utility model relates to the technical field of tilling machines, and in particular to a tilling machine with adjustable rotary tillage depth. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete ploughing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after ploughing. Most of the existing rotary tillers have an adjustment effect during use, and can control the depth of cultivated land according to usage requirements. However, most of the existing rotary tillers adjust the rotary tillage components by adjusting the drive components. When the drive components are damaged, it is inconvenient for the user to adjust the rotary tillage components, which directly affects the normal use of the rotary tiller.

[0003] After searching, the Chinese patent publication number is CN 219981777U, which discloses a rotary tiller with adjustable tillage depth. In this patent, an adjustment mechanism is installed to achieve that the rotary tiller body can adjust the depth of the rotary tillage harrow according to the use requirements when performing tillage operations. The manual adjustment method is more convenient for users to control the height of the tillage harrow, while avoiding the inconvenience caused by the traditional drive component adjustment, thereby improving the flexibility and practicality of the rotary tiller with adjustable tillage depth.

[0004] However, when the above device is used, manual operation is first required to change the tillage depth of the rotary tiller, and the adjustment process is time-consuming. At the same time, the adjustment method of the limit mechanism makes the adjustment process cumbersome and the overall process is relatively time-consuming. Utility Model Content

[0005] The utility model provides a tilling machine with adjustable rotary tillage depth, which has the advantage of automatic or manual rapid adjustment of the rotary tillage depth, and solves the problem in the related art that the rotary tillage depth cannot be adjusted quickly automatically or manually.

[0006] The technical scheme of the utility model is as follows: a tilling machine with adjustable rotary tillage depth comprises a body, wherein slide grooves are provided on both the front and rear sides of the middle part of the body, a slider is movably installed in the inner cavity of the slide groove, a round shaft is movably installed in the middle part of the slider, a first motor is fixedly installed on the front side of the front slider, a roller is fixedly installed in the middle part of the outer surface of the round shaft, a plurality of tilling knives are fixedly installed on the outer surface of the roller, vertical plates are fixedly installed on the tops of the opposite sides of the front and rear sliders, a plurality of teeth are fixedly installed on the left and right sides of the vertical plates, a plurality of threaded holes are provided on the top of the front side of the body, a turntable is movably installed on the front side of the body through a rotating shaft, a limiting column is fixedly installed on the front side of the turntable, a limiting block is movably installed in the inner cavity of the limiting column, a threaded rod is fixedly installed in the middle part of the limit block, and a handle is fixedly installed on the front side of the threaded rod.

[0007] Preferably, a second motor is fixedly installed on the rear side of the top of the vehicle body, a disc is detachably installed on the rear side of the second motor through an output shaft, wheels are rotatably installed on both the front and rear sides of the left and right sides of the vehicle body, and a push handle is fixedly installed on the left side of the vehicle body.

[0008] Preferably, the shape of the cross-section of the inner cavity of the slide and the shape of the cross-section of the slider are both irregular shapes, and the shape of the cross-section of the inner cavity of the slide matches the shape of the cross-section of the slider, so that when in use, the slider cannot be moved out of the inner cavity of the slide due to the shape of the slider and can only move up and down in the inner cavity of the slide.

[0009] Preferably, the tooth shape on the left and right sides of the front vertical plate matches the shape of the edge of the outer surface of the turntable, so that when in use, the staff drives the turntable to rotate by rotating the handle, and then drives the front vertical plate to move up or down, thereby controlling the upward or downward movement of the roller and realizing the adjustment of the rotary tillage depth of the tiller.

[0010] Preferably, the outer surface of the threaded rod is provided with threads matching the inner wall of the threaded hole, and the threaded holes are evenly distributed directly behind the turntable. Therefore, when in use, the number and distribution of the threaded holes make it easy to assemble the threaded rod with the rear threaded holes after the turntable is rotated to any angle, thereby fixing the turntable and then fixing the front vertical plate to prevent the position of the roller from changing.

[0011] Preferably, circular holes are provided on the front and rear sides of the inner cavity of the limit column, the shape of the cross-section of the inner cavity of the limit column is larger than the shape of the cross-section of the circular holes on the front and rear sides of the limit column, the shape of the cross-section of the limit block matches the shape of the cross-section of the inner cavity of the limit column, and the shape of the cross-section of the inner cavity of the circular hole matches the shape of the cross-section of the threaded rod. Therefore, when in use, due to the limit block, the threaded rod can only move forward and backward in the middle part of the limit column, thereby preventing the threaded rod from falling off.

[0012] Preferably, the first motor and the second motor are both forward and reverse motors, the output shaft of the first motor is connected to the circular shaft, and the output shaft of the second motor is connected to the disc. The first motor and the second motor are both fixedly mounted with control switches on their outer surfaces, so that when in use, the first motor or the second motor is started and shut down by the control switch. The first motor starts to control the rotation of the drum and then drives the plowing knife to rotate, so as to cultivate the land. The second motor starts to control the disc to rotate forward or reverse as needed.

[0013] Preferably, the shape of the outer surface of the disc matches the shape of the teeth distributed on the left and right sides of the rear vertical plate, so that after the second motor is started, it drives the disc to rotate, thereby controlling the rear vertical plate to move up and down, thereby covering the position of the plate roller.

[0014] The working principle and beneficial effects of the utility model are:

[0015] 1. The tilling machine with adjustable rotary tillage depth is used by the cooperation of the handle structure and the threaded rod structure. When working, the second motor cooperates with the disc to drive the rear vertical plate to move up and down, so as to control the up and down movement of the roller and the tilling blade, thereby changing the rotary tillage depth. When the second motor is damaged, the handle is manually rotated to cooperate with the turntable to drive the front vertical plate to move up and down, so as to control the up and down movement of the roller and the tilling blade, thereby changing the rotary tillage depth. After adjustment, the handle is rotated backward to allow the threaded rod to be inserted into the rear threaded hole, so as to fix the turntable, thereby achieving the advantage of automatic or manual rapid adjustment of the rotary tillage depth.
