Description

Technical Field

[0001] The invention relates to the technical field of ground film recovery machines, in particular to a film recovery machine for agricultural use suitable for ground films of different depths. Background Art

[0002] Ground film refers to a film laid on the ground to cover crops or cultivated land. Its main function is to keep the soil moist, increase soil temperature, prevent weed growth, reduce water evaporation, etc. Since most domestic ground films are off-label products with a thickness of less than 0.008mm, a large amount of soil and rotten roots, stems and leaves of crops will adhere to the broken residual film after use, making it difficult to remove and separate the film. The ground film remaining in the stratum degrades slowly, which will hinder the exchange of moisture and air between the soil and the outside world, not only causing soil salinization and affecting the normal planting and growth of crops, but also reducing the working efficiency and quality of agricultural machinery.

[0003] Therefore, in the current production, people have paid full attention to the recycling of used ground film, and centralized recycling through various machines, so that most of the residual film in production can be recycled, and large-scale pollution can be suppressed. Among them, the more common one is the roller harrow type film collecting machine, which mainly rolls a picking roller covered with thorny spikes in the land. The thorny spikes pick up the residual film in the land, and the picking roller is provided with a film brushing mechanism such as a roller brush to brush off the residual film on the thorny spikes and recycle it. The structure of this type of mechanism is relatively simple, and it can be combined with various operating machines for joint operation, especially It is suitable for auxiliary operations in various farming operations, but the current picking device in this type of residual film recovery machinery has an obvious shortcoming: during the operation, there will always be residual film and plant straw that are difficult to be brushed off by the film brushing mechanism in time and are constantly entangled on the thorny spikes of the drum. This accumulation on the thorny spikes of the drum requires continuous suspension of operations for cleaning in order to operate normally. The common cleaning method is usually to add a table saw to the roller harrow film collecting machine and perform cutting when the machine is stopped. The above method requires the additional addition of a screw-driven transverse moving component and a motor table saw, which greatly increases the cost of use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a film recycling machine suitable for agricultural use at different depths of ground film is proposed. Summary of the invention

[0005] The object of the present invention is to provide a film recovery machine suitable for agricultural use at different depths of ground films, so as to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, a mounting frame is fixed at the front end of the frame, and the mounting frame is mounted on a three-point suspension mechanism at the rear of the tractor. A transmission box is fixed at the middle of the mounting frame, and the transmission box is connected to the power output shaft of the tractor through a connecting shaft.

[0009] Furthermore, the transmission box is connected to a transmission shaft for side rotation transmission, and a transmission belt is mounted on the end of the transmission shaft.

[0010] Furthermore, a film collecting assembly is rotated in the middle of the frame, and the film collecting assembly includes a pulley, a spline sleeve and a picking roller. The pulley is connected to the transmission shaft through a transmission belt, and a spline sleeve is coaxially fixed on the inner side of the pulley, and the picking roller is coaxially connected to the inner side of the spline sleeve.

[0011] Furthermore, the film collecting assembly also includes side grooves and film picking rods. The side ring array of the picking roller is provided with side grooves, and film picking rods are fixed between adjacent side grooves. The film picking rods cooperate with the film picking grid forks to pick up the residual film in the soil.

[0012] Furthermore, the film collecting assembly also includes a telescopic rod, a cone mouth and a spline shaft. The telescopic rod is slidably installed inside the picking roller, and several cone mouths are opened in the middle of the telescopic rod. A spline shaft is coaxially fixed at the root of the telescopic rod, and the spline shaft cooperates with the spline sleeve.

[0013] Furthermore, the film collecting assembly also includes a bearing, a connecting plate and an electric cylinder. The root of the telescopic rod is rotatably matched with the bearing, and the bearing is arranged on one side of the connecting plate. The other side of the connecting plate is fixedly connected to the output end of the electric cylinder, and the electric cylinder is fixed to the side of the gap between the cross bar and the rear end of the frame.

[0014] Furthermore, a film cutting assembly is correspondingly arranged inside the side groove, and the film cutting assembly includes a mounting plate, a cutting blade, a connecting rod and a steel ball. The mounting plate is slidably installed inside the side groove, and a cutting blade is fixed on one side of the mounting plate, a connecting rod is fixed on the other side of the mounting plate, and a steel ball is rotatably installed at the end of the connecting rod, and the steel ball fits with the cone in the middle of the telescopic rod.

[0015] Furthermore, the film cutting assembly also includes a middle ring and a spring. The middle ring is fixed to the root of the connecting rod, and the spring is sleeved on the middle of the connecting rod.

[0016] The present invention provides a film recycling machine for agricultural use suitable for mulch films of different depths, which has the following beneficial effects: 1. During the use of the present invention, the hanging frame at the front end of the frame is hung with the three-point hanging mechanism at the rear of the traction tractor, and the tractor is used to tow the ground film recycling machine of the present application to move. During operation, the film-lifting fork hinged at the rear end of the frame enters the soil and picks up the soil layer mixed with the ground film. The user can rotate the worm by a hand wheel, and the worm rotates and transmits to the worm wheel engaged to the side, and further controls the lifting and lowering through the threaded cooperation of the worm wheel and the middle lifting rod, so that the film-lifting fork is offset around the rear end rotating pin as the center, thereby adapting to the collection needs of ground films of different depths. The present application is different from the fixed film-lifting fork of the traditional technology in that not only can the film-lifting depth of multiple film-lifting forks be adjusted synchronously, but also the lead angle of the worm in the design is smaller than the equivalent friction angle between the teeth of the worm wheel, so that the mechanism has self-locking property and can realize reverse self-locking, that is, the worm wheel can only be driven by the worm, but the worm wheel cannot drive the worm. Its reverse self-locking property can play a safety protection role, and is also convenient for the operator to perform manual batch adjustment, which is more convenient to use.

[0017] 2. During the use of the present invention, the transmission box in the middle of the mounting frame is connected to the power output shaft of the traction tractor through the connecting shaft, and is further rotated to the pulley through the transmission belt at the end of the transmission shaft. The residual film in the soil layer is picked up and wound around the drum body through the film picking rods evenly distributed around the circumference of the picking drum. During this period, the built-in telescopic rod of the picking drum is synchronously rotated under the action of the bearing through the cooperation of the spline shaft and the spline sleeve at the root. In the traditional technology, as the ground film wound around the drum body gradually increases, it is necessary to stop the machine and cut it with a table saw to avoid affecting subsequent operations. However, the present application does not require shutdown processing, and only needs to reduce the traction speed of the tractor, and activate the electric cylinder to drive the connecting plate to contract. The connecting plate further drives the telescopic rod to move in the internal cavity of the picking drum. The tapered opening in the middle of the telescopic rod squeezes the steel ball at the rear end of the connecting rod in the film cutting assembly, causing the middle ring extrusion spring to deform and drive the cutting blade at the front end of the mounting plate to protrude out of the side groove, so that the ground film wound on the cylinder body can be cut, and the broken ground film after cutting is further collected and recycled. The ground film cutting operation in the above process does not interfere with the rotation and collection process of the picking roller. In other words, even in the cutting operation process, the film picking rod on the circumference of the picking roller can still pick up and wind the ground film in the soil layer normally, and there is no need to stop the machine, which greatly improves the production efficiency. Moreover, the ground film removal operation of the present application only requires one electric cylinder as the power source, which greatly reduces the production cost compared to the prior art which requires the additional screw-driven transverse moving component and the motor-driven table saw structure.
