Description

Technical Field

[0001] This utility model relates to the technical field of maintenance devices, and in particular to a soil turning and maintenance device. Background Technology

[0002] Agricultural machinery comes in various types and is mainly used for tasks such as tilling and fertilizing in agricultural planting. These machines have a tilling structure at the rear and perform tilling operations at different locations during movement. Before the next planting, insect eggs buried underground need to be turned over to expose them to sunlight, and then insecticides can be sprayed to kill them. This process also helps maintain the soil's health.

[0003] However, the blades of traditional tillers are usually fixed on the rotating shaft, and the width that the blades can cover during rotation is not adjustable, making them unsuitable for tilling ridges of various widths. Therefore, an adjustable tiller blade was designed to address the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a soil turning and maintenance device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

Therefore, they should not be construed as limitations on this utility model.

[0026] Given the current technology, the traditional tillage machine's tillage blades are usually fixed on the rotating shaft, and the width range that the tillage blades can cover during rotation is not adjustable, making it unsuitable for tilling ridges of various widths.

[0027] As shown in the attached figure, this utility model embodiment provides a soil turning and maintenance device.

[0028] The system includes: a plow blade 12 at the bottom of a mounting frame 11; an adjustment assembly 2 inside the mounting frame 11, the adjustment assembly 2 including: a crossbar 21 welded to the inner side of the mounting frame 11; a slider 22 passed through the crossbar 21 and sliding on the crossbar 21, with its bottom fixedly connected to the plow blade 12; a through groove 23 at the bottom of the mounting frame 11; a plate 24 inside the mounting frame 11; a guide groove 25 at the top of the plate 24; a protrusion 26 whose bottom end passes through the guide groove 25 and the through groove 23 and is connected to the top of the slider 22; a telescopic motor 27 inside the mounting frame 11 and fixedly connected by a clamp; and a connecting plate 28 welded and fixedly installed on the top of the plate 24 and fixedly connected to the output end of the telescopic motor 27.

[0029] Specifically, the mounting frame 11 needs to be used in conjunction with a drive unit, such as a tractor, to move the mounting frame across the farmland. The plow blades 12 at the bottom of the mounting frame 11 can insert into the soil and till it, exposing insect eggs inside and thus maintaining the soil. The drive unit is existing equipment and is not shown in the attached drawings. The telescopic motor 27 is a worm gear telescopic motor 27, which typically has a self-locking function and is a worm gear reducer (such as the WPDA-70 model).

[0030] When the transmission ratio reaches 1:30 or higher, the worm gear structure naturally possesses reverse self-locking performance, which can prevent the equipment from slipping unexpectedly due to external forces or gravity.

[0031] In use, first connect the telescopic motor 27 to an external power source. The telescopic motor 27 extends, pushing the connecting plate 28 to move. Simultaneously, the connecting plate 28 drives the plate body 24 to move inside the mounting frame 11. During this movement, the protrusion 26 slides inside the guide groove 25. The guide groove 25 can drag the protrusion 26 to move equidistantly to both sides inside the through groove 23. The protrusion 26 drives the slider 22 at the bottom to slide on the crossbar 21. Subsequently, because the slider 22 is fixedly connected to the plow blades 12, the spacing between the plow blades 12 can be adjusted (this can be observed visually and measured with a measuring tape). The spacing of the plow blades 12 can be adjusted according to the soil type and hardness. The spacing of the plow blades 12 is usually 1.2 times the diameter of the plow blades 12. For example, if the diameter of the plow blades is 10 cm, the spacing should be set to 12 cm. The adjustment range is an increase of 5 cm from the original 12 cm.

[0032] In some embodiments, the protrusion 26 is a round rod design.

[0033] The round rod has a smooth surface without sharp edges, which reduces scratches when sliding inside the guide groove 25.

[0034] In some embodiments, two sets of the telescopic motor 27 and the connecting plate 28 are symmetrically arranged.

[0035] Two sets of symmetrically arranged plates 24 can move more stably inside the mounting bracket 11.

[0036] In some embodiments, the slider 22 is provided with a fixing component 3, the fixing component 3 including: a rectangular groove 31 formed at the bottom of the slider 22; a through hole 32 formed at the outer side wall of the slider 22 and the plow blade 12; one end of a bolt 33 passing through the through hole 32; and a nut 34 sleeved on one end of the bolt 33 and threadedly connected to the bolt 33.

[0037] When the plowing blade 12 needs to be installed, simply insert the top of the plowing blade 12 into the rectangular groove 31, align the through hole 32 on the plowing blade 12 with the through hole 32 on the slider 22, insert the bolt 33 through the through hole 32 and tighten it with the nut 34 to complete the installation of the plowing blade 12.

[0038] In some embodiments, the fixing component 3 further includes a cone 35 fixedly disposed at one end of the bolt 33.

[0039] The pointed end of the cone 35 is relatively easier to penetrate the inside of the through hole 32.

[0040] In some embodiments, the outer sidewall of the top of the plow blade 12 is fitted with the inner sidewall of the rectangular groove 31.

[0041] The fitted design allows the plow blade 12 to be better restrained after installation, making it less prone to wobbling.

[0042] In some embodiments, the fixing component 3 further includes: a groove 36 formed on the outer side wall of the top end of the plow blade 12; a groove 37 formed on the inner side wall of the rectangular groove 31; a spring 38 fixedly disposed inside the groove 37; and an arc-shaped block 39 inserted at one end into the groove 37 and fixedly connected to the spring 38.

[0043] When the top of the plowing blade 12 is inserted into the rectangular groove 31, it will compress the arc-shaped block 39, causing the spring 38 to be compressed. After one end of the arc-shaped block 39 is aligned with the groove 36, the spring 38 will rebound and push one end of the arc-shaped block 39 into the groove 36. At the same time, the through hole 32 on the plowing blade 12 is aligned with the through hole 32 on the slider 22, making it easy to pass the bolt 33 through the through hole 32.

[0044] In some embodiments, two sets of grooves 36 and grooves 37 are provided on opposite sides.

[0045] Two sets of symmetrically arranged plow blades 12 can better stabilize them, making it less likely for their tips to detach from the rectangular groove 31. The through holes 32 are aligned for easy installation.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
