Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of self-adhesion harvester sealing plate technical field, specifically, a kind of self-adhesion harvester sealing plate. BACKGROUND
[0002] Harvester sealing plate is also called cutterbar sealing rubber plate, and the cutterbar sealing rubber plate is an important component in the harvester, which is used to ensure the sealing performance of the cutterbar (also known as the delivery table or the cutting stem device) of the harvester, to prevent the leakage of crops during harvesting. This rubber plate is usually made of rubber or similar materials, and its design aims to conform to the surface of the cutterbar of the harvester and ensure effective sealing during operation to prevent the loss of grains or other harvested materials. Its working principle is to cover the gap between the delivery table and the delivery roller with a plate, so that the roots and leaves of crops will not be stuck in the gap when they fall into the delivery table, thereby enabling the equipment to operate continuously and stably.

The contact gap between the sealing plate and the delivery table will gradually increase, and the vibration caused by the operation of the harvester will exacerbate the shaking of the sealing plate on the delivery table, thereby exacerbating the wear of the sealing plate. The severely worn sealing plate will be misaligned, which will cause the gap between the delivery table and the delivery roller to leak, reduce the working efficiency of the cutting machine, and increase the maintenance cost of the equipment.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0023] like Figures 1-6 As shown, this embodiment proposes a self-adhesive harvester sealing plate, including a harvester conveyor table 1, several bolts 2 and nuts 4. Each bolt 2 is fixedly connected to the upper side of the harvester conveyor table 1, and each bolt 2 is threadedly connected to each nut 4. A sealing plate 3 is connected to the harvester conveyor table 1 by the bolts 2 and nuts 4. Several pressure blocks 5 are fixedly connected to the sealing plate 3. Magnetic columns 6 attracted by the harvester conveyor table 1 are connected between each pressure block 5 and the sealing plate 3 by magnetic force. Several pressure grooves 31 are formed on the sealing plate 3 near the pressure blocks 5. The pressure grooves 31 can allow pressure to be removed from the bolts. The panel on one side can be flipped downwards around the pressure groove 31. Under the action of the pressure block 5, the weight of this part of the panel is increased, so that this part of the panel can better fit the upper side of the harvester conveyor table 1. Even if this part of the panel is worn, it can still fit the upper side of the harvester conveyor table 1, reducing grain leakage and increasing the protective effect of the sealing rubber plate 3. The first rubber strip 36 is fixedly connected to the side of the sealing rubber plate 3 away from the pressure block 5. The first rubber strip 36 can increase the friction between the sealing rubber plate 3 and the harvester conveyor table 1, making the connection between the sealing rubber plate 3 and the harvester conveyor table 1 tighter.
[0024] like Figure 5 As shown, the second limiting groove 34 is formed on the sealing rubber plate 3, and several first limiting grooves 33 and third limiting grooves 35 are respectively formed on both sides of the second limiting groove 34. The inner walls of the first limiting groove 33, the second limiting groove 34 and the third limiting groove 35 are all in contact with the bolts 2. The sealing rubber plate 3 is aligned and connected with the bolts 2 on the harvester conveyor table 1 through the first limiting grooves 33, the second limiting grooves 34 and the third limiting grooves 35, which facilitates the installation by the installers.
[0025] like Figure 5As shown, the inner wall side of the first limiting groove 33 and the third limiting groove 35 are perpendicular to each other, and after the sealing rubber plate 3 is connected with the bolt 2, the inner wall of the first limiting groove 33 and the inner wall of the third limiting groove 35 respectively abut against the bolt 2 without tightening the nut 4, the sealing rubber plate 3 is limited in the moving direction except the vertical up and down movement, that is, through the opening mode that the inner wall side of the first limiting groove 33 and the third limiting groove 35 are perpendicular to each other, the sealing rubber plate 3 can be limited in five degrees of freedom through the connection with the bolt 2, and then after the nut 4 is installed and fastened, the working pressure of the nut 4 can be reduced and the fastening effect of the nut 4 on the sealing rubber plate 3 can be increased.
[0026] As shown in Figures 1-3 The counterweight 7 is fixedly connected to the side of the sealing rubber plate 3 away from the pressure block 5, and through the counterweight 7, the sealing rubber plate 3 can be better attached to the upper side of the harvester conveying table 1.
[0027] As shown in Figures 1-3 A plurality of limiting holes 32 are formed in the sealing rubber plate 3, the inner wall of each limiting hole 32 abuts against each magnetic column 6, so that the magnetic column 6 can be placed in the limiting hole 32, and through the magnetic attraction of the magnetic column 6 to the harvester conveying table 1, when the sealing rubber plate 3 is worn, the sealing rubber plate 3 can still be attached to the surface of the harvester conveying table 1.
[0028] As shown in Figures 1-4 The pressure block 5 includes two second rubber strip particles 51, and the rubber strip block 52 is fixedly connected between the two second rubber strip particles 51, so as to increase the strength of part of the sealing rubber plate 3, prevent excessive deformation of part of the sealing rubber plate 3, and increase the service life of the sealing rubber plate 3.
[0029] The working principle of the embodiment is as follows:
[0030] Each nut 4 is unscrewed, then each bolt 2 is aligned with the first limiting groove 33, the second limiting groove 34 and the third limiting groove 35, the sealing rubber plate 3 is placed on the harvester conveying table 1, then after the first limiting groove 33, the second limiting groove 34 and the third limiting groove 35 are all clamped with the bolt 2, each nut 4 is tightened, the sealing rubber plate 3 is completely clamped on the harvester conveying table 1, and the panel on the side of the sealing rubber plate 3 away from the nut 4 is assisted by the pressure groove 31, so that this part of the panel can be turned down and deformed by its own gravity around the pressure groove 31, so that this part of the panel can be bent, and then through the adsorption of each magnetic column 6 to the harvester conveying table 1, the panel on the side of the sealing rubber plate 3 away from the nut 4 can be always automatically attached to the harvester conveying table 1, the counterweight 7 keeps part of the panel always bent downward, so that the sealing rubber plate 3 can completely cover the gap between the harvester conveying table 1 and the conveying roller, preventing particles from falling into the gap.
[0031] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
