Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a nylon frame for a cotton picker doffer. Background Art

[0002] In the process of agricultural modernization, cotton picking has gradually shifted from traditional manual picking to mechanized picking. The emergence of cotton pickers has greatly improved the efficiency of cotton picking and met the needs of large-scale cotton planting industry. The cotton picker is one of the key components of the cotton picker, and its performance directly affects the quality and efficiency of cotton picking. With the continuous expansion of cotton planting area and higher requirements for picking speed, it is necessary to continuously optimize the performance of various components of the cotton picker. The traditional cotton picker structure has gradually exposed some problems during long-term use, such as insufficient strength and poor wear resistance, which has prompted innovation in the material and structure of the cotton picker.

[0003] However, when the existing doffer disc frame is in use, the inner frame is usually made of a steel frame, and the steel frame needs to be equipped with a customized spacer sleeve for use. During its installation and use, the steel frame will cause wear to the polyurethane doffer disc cast on the outside when it rotates at high speed. In the long run, the outer polyurethane doffer disc will be damaged, and the steel frame and the polyurethane doffer disc are not easy to stick together, and idling will occur during the rotation process.

[0004] Therefore, we provide a nylon frame for cotton picker doffer disc to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a nylon frame for a cotton picker doffer disk, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a nylon frame for a cotton picker doffer disk, comprising a doffer disk body and a fixed spacer vertical sleeve, wherein one side of the doffer disk body is provided with a fixed spacer vertical sleeve;

[0007] A fixed spacer sleeve is fixedly connected to the middle of one side of the doffer disc body, a fixed support frame is fixedly connected to the edge of the doffer disc body, a fixed casting hole is opened on the surface of the fixed support frame, and a fastening tooth is provided on the edge of the fixed support frame.

[0008] Preferably, the fixed spacer sleeve is an inner hollow structure, and the middle hole passes through the main body of the doffing disc.

[0009] Preferably, the edge of the doffer disc body is fixedly connected to a fixed support frame, and the heights of the upper and lower surfaces of the doffer disc body are slightly higher than the fixed support frame.

[0010] Preferably, fixed casting holes are opened on the surface of the fixed support frame, and the fixed casting holes are evenly opened on the surface of the fixed support frame with the fixed interval sleeve as the center.

[0011] Preferably, the outer side of the fixed support frame is fixedly connected with fastening teeth, and the fastening teeth are fixedly connected to the outer side of the fixed support frame at the same intervals.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Through the setting of the cotton dozer main body, when in use, the entire cotton dozer frame is changed from the original steel to nylon material. The nylon cotton dozer main body and the fixed support frame are easier to adhere and fix with polyurethane, increasing the cohesive force, and the contact surface is not easy to fall off. In the figure, the height of the cotton dozer main body is higher than the fixed support frame at the edge, and a tooth block is fixed on the edge. After pouring and cooling, the surface protrusions will clamp and fix the inner side of the entire cotton dozer to ensure that the cotton dozer will not fall off during the forward and reverse rotation process. The polyurethane solution will adhere to the fixed support frame through the fixed pouring holes on the surface of the cotton dozer main body, and be fixed to the frame after cooling. The outer fastening teeth can perform secondary fixation on the frame edge when pouring the polyurethane solution. In addition, nylon material is lighter than steel, has the advantages of impact resistance, good flexibility, no degumming and more durability, which reduces the load on the cotton picker head, can reduce the load wear of the connection part, and increase the service life of the picking head.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-2As shown, the utility model provides a technical solution: a nylon frame for a cotton picker doffer disk, comprising a doffer disk body 1 and a fixed spacer sleeve 2, wherein the fixed spacer sleeve 2 is provided on one side of the doffer disk body 1;

[0019] A fixed spacer sleeve 2 is fixedly connected to the middle of one side of the doffer disc body 1, and a fixed support frame 3 is fixedly connected to the edge of the doffer disc body 1. Fixed casting holes 4 are opened on the surface of the fixed support frame 3, and fastening teeth 5 are provided on the edge of the fixed support frame 3.

[0020] Furthermore, the fixed spacer sleeve 2 is an internal hollow structure, and the middle hole passes through the cotton dozer main body 1. The cotton dozer main body 1 and the fixed spacer sleeve 2 are both made of nylon. In the process of casting the polyurethane cotton dozer main body in the customized mold, the nylon cotton dozer main body 1 is more easily adhered and fixed to the polyurethane.

[0021] Furthermore, the edge of the decottoning disc body 1 is fixedly connected to a fixed support frame 3, and the heights of the upper and lower surfaces of the decottoning disc body 1 are slightly higher than the fixed support frame 3. By setting the height of the decottoning disc body 1 higher than the fixed support frame 3 at the edge, and the front and back sides of the connection between the decottoning disc body 1 and the fixed support frame 3 are both trapezoidal protrusions, it is intended to strengthen the adhesion and friction between the polyurethane and the fixed casting holes 4 and the fixed support frame 3, and the edge shape of the protrusion can be any shape, which can have the same effect. After the casting is cooled, the protrusion of the inner decottoning disc body 1 will clamp and fix the inner side of the entire decottoning disc to ensure that the decottoning disc will not fall off during the forward and reverse rotation process.

[0022] Furthermore, fixed casting holes 4 are opened on the surface of the fixed support frame 3, and the fixed casting holes 4 are evenly opened on the surface of the fixed support frame 3 with the fixed interval sleeve 2 as the center. By opening a plurality of fixed casting holes 4 on the surface of the fixed support frame 3, and the fixed casting holes 4 can be of any shape, during the casting process, the polyurethane solution will adhere to the fixed support frame 3 through the fixed casting holes 4, so that it will be fixed to the fixed support frame 3 after cooling.

[0023] Furthermore, the outer side of the fixed support frame 3 is fixedly connected with fastening teeth 5, and the fastening teeth 5 are fixedly connected to the outer side of the fixed support frame 3 at the same interval. A circle of fastening teeth 5 is evenly fixed on the outer side of the fixed support frame 3. Similarly, the fixed support frame 3 can be fixed for a second time during the pouring of the polyurethane solution to prevent the fixed support frame 3 and the polyurethane doffing disk from falling off during the rotary cotton picking process.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
