As described in the background art, there are deficiencies in the prior art, in order to solve the above technical problems, the present invention proposes a conveyor belt type residual film cleaning device including a residual film recovery machine of the device.

In a typical embodiment of the present invention, as shown in FIG. 3 and FIG. 4 , a conveyor belt-type residual film cleaning device disclosed in this embodiment is mainly composed of a bearing seat 6-1, a column 6-2, a conveyor belt Belt pallet 6-3, conveyor belt 6-4, conveyor belt tooth 6-5, beam 6-6, sprocket 6-7, discharge port 6-8;

Among them, the beams 6-6 include two, the two beams 6-6 are arranged in parallel with each other, the column 6-2 includes four, and the four columns are used to support the two beams and are installed at both ends of the two beams There are sprockets, the sprockets are driven by the power on the residual film recovery machine to rotate, the sprockets 6-7 are used to transmit power to drive the conveyor belt 6-4 to move, and the conveyor belt 6-4 is arranged between the two beams. The conveyor belt 6-4 is used to receive the fallen debris and transport the debris to the side of the elastic tooth chain rake type residual film recovery machine to return to the field.

Further, in order to effectively catch the falling debris, the center distance of the conveyor belt is generally not less than 2200mm, and the width is generally not less than 200mm; see Figure 5, Figure 6, and Figure 7 for details.

Further, during the movement of the conveyor belt 6-4, when the sundries fall on the conveyor belt, due to the influence of sliding friction, the sundries cannot move with the conveyor belt immediately, which affects the cleaning of sundries; A number of conveyor belt teeth 6-5 are added to assist in cleaning debris, and the conveyor belt teeth 6-5 are perpendicular to the moving direction of the conveyor belt. And in order to further ensure that the conveyor belt teeth 6-5 can effectively drive the sundries falling on the conveyor belt, the height of the conveyor belt teeth 6-5 cannot be lower than 25mm, and the length is the same as the conveyor belt width.

Further, the discharge openings 6-8 are used to guide the sundries to fall back into the field, which are arranged at the ends of the two beams. In this embodiment, the discharge openings 6-8 are only set at one end of the beams, which is not difficult to understand. In other embodiments, a discharge port can also be set at the other end of the beam. When the conveyor belt is conveyed in the opposite direction, the material can be discharged from another discharge port. The structure of the discharge port is shown in Figure 10. , which includes two connecting parts and an inclined part with a certain inclination angle; the two connecting parts are connected with the beam, the inclined part is inclined downward, and is located between the two beams, and the conveyor belt 6-4 transports the soil blocks in the residual film / Straw, etc. are transported to the discharge port, and slide down the slope into the field.

Further, based on the above-mentioned conveyor belt type residual film cleaning device, this embodiment also discloses a spring-tooth chain rake type residual film recovery machine, which is used for the surface and surface of farmland residual film. Residual film recovery of the plough layer. The whole machine of elastic tooth chain rake type residual film recovery machine is shown in Figure 1 and 2. The whole machine consists of film collecting box 2, residual film conveying device 2, pressing roller 4, elastic tooth chain rake type residual film pickup and conveying device 5 , Conveyor belt type residual film cleaning device 6, walking wheel 7, film breaking roller 8, straw returning device 9 and so on. The conveyor belt type residual film cleaning device is shown in Figure 2 for details. The installation position of the conveyor belt type residual film cleaning device is shown in Figure 2. On the frame of the pickup and conveying device, specifically, it is installed at the rear and under the elastic tooth chain rake type residual film pickup and conveying device 5, and at the same time, it is installed under the air inlet of the air collecting hood of the residual film conveying device; the film conveying support plate 11. The frame is connected, and this position can effectively catch the clods/straw and other sundries falling from the top of the film conveying support plate.

The working process of the elastic tooth chain rake type residual film recovery machine is divided into: straw crushing and returning to the field - film breaking roller breaking film - elastic tooth entering the soil to pick the film - the residual film is lifted up with the elastic tooth - conveying the residual film to the film collecting box through the conveying device Five links. When working, the machine is driven by the rear power output shaft of the tractor, and the straw returning device will crush the straw and return it to the field and blow it to the back of the elastic tooth chain rake type residual film recovery machine. Pick up the broken residual film (the elastic tooth chain rake rotates clockwise), and the picked up residual film is transported upward along the film conveying support plate under the hook and pulling action of the film pick-up elastic teeth. When the residual film is conveyed to the conveying film support When it is above the plate, the residual film on the film pick-up spring teeth will be sucked down by the residual film conveying device and blown into the film collecting box. To the conveyor belt type residual film cleaning device 6, and discharge to the field on one side of the elastic tooth chain rake type residual film recovery machine.

Working principle: During the working process of the conveyor belt type residual film cleaning device, the power of the tractor is transmitted to the sprocket under the action of the transmission system, and the sprocket drives the conveyor belt to move; After the spring teeth move to the top of the film conveying support plate, due to the difference in the quality and density of the clod/straw and the residual film, the clod/straw will fall to the conveyor belt of the residual film cleaning device, and the combined action of the conveyor belt and the conveyor belt teeth Down, move to the side of the elastic tooth chain rake type residual film recovery machine, and fall back to the field ground through the discharge port to complete the cleaning work.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
