Description

Technical Field

[0001] This utility model belongs to the field of soil sealing machine technology, specifically, it relates to the chassis of a telescopic variable amplitude automatic height adjustment obstacle-crossing soil sealing machine. Background Technology

[0002] In cotton and bell pepper cultivation, soil sealing machines achieve four core functions through mechanical soil sealing operations: moisture retention, temperature increase, weed control, and wind protection, while improving operational efficiency and reducing labor costs.

[0003] Current soil sealing machine technology is developing towards intelligence and multi-functionality. By integrating GPS navigation into the automatic soil sealing machine, precise soil covering can be achieved. Combined with sensors to monitor soil moisture, the soil covering thickness can be automatically adjusted. Typically, there are drip irrigation tapes every tens or hundreds of meters during the operation of the soil sealing machine. However, the rotary tillage device on the chassis of the existing soil sealing machine is prone to hitting the drip irrigation tape during the movement, which can easily cause the drip irrigation tape to be twisted and broken. In other words, the existing soil sealing machine lacks obstacle crossing ability.

[0004] Chinese patent application CN2022215220131 discloses a rotary tiller for sealing cotton plants. The machine includes a frame connected to a tractor. The frame is equipped with a walking device, a power transmission device, rotary tillers on both sides of the frame, a conveying device, and a diverting device. The power transmission device is driven by the tractor's power unit, and is driven by the rotary tillers. The rotary tillers are driven by the conveying device. The tractor pulls the frame, which moves via the walking device. This invention features a reasonable structural design, a high degree of automation, and the ability to seal multiple rows of seedlings with good sealing effect.

[0005] However, the frame in this design is an integrated structure, which has weak obstacle avoidance capabilities and is prone to damaging the drip irrigation tape during operation. Utility Model Content

[0006] The main technical problem to be solved by this utility model is to provide a chassis for a telescopic variable amplitude automatic height adjustment obstacle-crossing earth sealing machine with a simple overall structure that can automatically adjust part of the height during the operation of the earth sealing machine to avoid obstacles and improve the use effect.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A chassis for a telescopic variable amplitude automatic height adjustment obstacle-crossing soil sealing machine includes an outer frame. A fixed bracket is fixedly installed on one side of the inner side of the outer frame, and a movable bracket is movably installed on the other side of the inner side of the outer frame. The movable bracket is hinged to the fixed bracket through multiple sets of rotating devices. A hydraulic cylinder is hinged to the middle of both ends of the outer frame, and the power output end of the hydraulic cylinder is hinged to the movable bracket.

[0009] The following are further optimizations of the above technical solution by this utility model:

[0010] The fixed bracket includes first short rods fixedly installed at both ends of the length direction inside the outer frame, and multiple second short rods fixedly installed between the two first short rods inside the outer frame, with the multiple second short rods parallel to the two first short rods.

[0011] Further optimization: The movable support includes rotary tillage supports located at both ends of the length direction inside the outer frame, with the two rotary tillage supports corresponding to the positions of the two first short rods and the second short rods near the first short rods, respectively.

[0012] Further optimization: The rotary tillage support is made of square tubes of different lengths into a U-shaped structure, and the open end of the U-shaped structure is respectively hinged to a first short rod and a second short rod.

[0013] Further optimization: A motor reducer bracket is hinged on the fixed bracket between the two rotary tillage brackets, and the two ends of the reducer bracket are fixedly connected to the second connecting rod through the first connecting rod and the second connecting rod, respectively.

[0014] Further optimization: The rotating device includes an ear plate assembly and a rotating block hinged together.

[0015] Further optimization: The ear plate assembly includes two symmetrically spaced rotating ear plates, with the same rotating pin fixedly installed on the two rotating ear plates, and one end of the rotating block is movably sleeved on the rotating pin.

[0016] Further optimization: The other end of the rotating block is fixedly installed on the corresponding rotary tillage bracket and the second connecting rod, and the ear plate assembly is fixedly installed on the corresponding first connecting rod and the second connecting rod.

[0017] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. When the sealing machine encounters obstacles during use, it can automatically raise the movable support part with the transmission mechanism in the chassis, avoid repeated damage to the transmission mechanism, reduce maintenance rate, extend service life, and facilitate use.

[0018] When encountering an obstacle during travel, the hydraulic cylinder is activated from the tractor cab. The power output end of the cylinder extends, causing the vertical rod and movable support to rise. Simultaneously, under the action of the rotating device, the movable support rotates on the fixed support, and the transmission mechanism on the movable support avoids the obstacle. This does not hinder the overall operation of the sealing machine and is easy to use. Once the obstacle is overcome, the hydraulic cylinder is activated again, causing the power output end of the cylinder to retract and drive the movable support to return. The operation is simple.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

A fixed bracket 2 is fixedly installed on one side of the inner side of the outer frame 1, and a movable bracket 3 is movably installed on the other side of the inner side of the outer frame 1. The movable bracket 3 is hinged to the fixed bracket 2 through multiple sets of rotating devices 4. Hydraulic cylinders 6 are hinged at the middle positions of both ends of the outer frame 1, and the power output end of the hydraulic cylinder 6 is hinged to the movable bracket 3.

[0024] In this embodiment, the outer frame 1 is a square frame structure made of multiple square tubes of different lengths. A tripod is installed on the outer frame 1, which is used to connect to the tractor. The specific structure is known in the prior art and will not be described in detail here.

[0025] The fixed bracket 2 includes two first short rods 21 fixedly installed at both ends of the length direction inside the outer frame 1, with the two first short rods 21 arranged perpendicularly to the side of the outer frame 1.

[0026] Inside the outer frame 1, between the two first short rods 21, there are multiple second short rods 22 that are spaced apart and are parallel to each other.

[0027] In this embodiment, the number of the second short rods 22 is set to four, with two second short rods 22 located near the first short rods 21, and the other two second short rods 22 located in the middle between the two first short rods 21.

[0028] The movable support 3 includes rotary tillage supports 31 located at both ends of the length direction inside the outer frame 1. The two rotary tillage supports 31 correspond to the positions of the two first short rods 21 and the second short rod 22 near the first short rods 21, respectively.

[0029] The rotary tillage support 31 is made of square tubes of different lengths into a U-shaped structure, and the open end of the U-shaped structure is respectively hinged to a first short rod 21 and a second short rod 22.

[0030] The rotary tillage support 31 is equipped with a rotary tillage device for a soil sealing machine. It is not shown in the figure. The rotary tillage device uses a cutter to take soil and cover it. It is a commonly used device in the prior art. The specific structure will not be described in detail here.

[0031] A motor reducer bracket 32 ​​is hinged on the fixed bracket 2 between the two rotary tillage brackets 31. The two ends of the motor reducer bracket 32 ​​are fixedly connected to the second connecting rod 34 via the first connecting rod 33, wherein the second connecting rod 34 is located near the rotating device 4.

[0032] In this embodiment, the motor reducer bracket 32 ​​is a square frame made of multiple square tubes of different lengths and multiple stainless steel plates. The motor reducer that provides power to the sealing machine is fixedly installed on the motor reducer bracket 32, which is not shown in the figure.

[0033] In this embodiment, the number of rotating devices 4 matches the number of the first short rod 21 and the second short rod 22, that is, a set of rotating devices 4 is provided at the end of each of the first short rod 21 and the second short rod 22.

[0034] The rotating device 4 includes an ear plate assembly and a rotating block 43 hinged together. The ear plate assembly includes two symmetrically spaced rotating ear plates 41.

[0035] Two rotating ear plates 41 are fixedly installed with the same rotating pin 42, and one end of the rotating block 43 is movably sleeved on the rotating pin 42.

[0036] The other end of the rotating block 43 is fixedly installed on the corresponding rotary tillage bracket 31 and the second connecting rod 34.

[0037] The ear plate assembly is fixedly installed on the corresponding first connecting rod 33 and second connecting rod 34.

[0042] With this design, when the hydraulic cylinder 6 is activated, the power output end of the hydraulic cylinder 6 extends, driving the vertical rod 5 to move upward, thereby lifting the movable support 3 upward and moving the rotary tillage device on the movable support 3 upward, thus preventing the auger from cutting the drip irrigation tape.

[0043] When the drip irrigation tape is passed, the power output end of the hydraulic cylinder 6 is retracted, the movable support 3 returns to its original position, and the rotary tillage device continues to take soil and cover it.

[0044] The control end of the hydraulic cylinder 6 is connected to the hydraulic system of the tractor, and the operation of the hydraulic cylinder 6 can be controlled from the tractor cab, which is convenient.

[0045] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
