Description

Technical Field

[0001] This utility model relates to the field of harvester technology, specifically a harvester header locking device. Background Technology

[0002] A harvester is an agricultural machine that harvests the fruit and returns the straw to the field in one go when the crops are ripe. The header is an important component that efficiently separates the ears of fruit from the stalks and transports them to the bridge via an auger.

[0003] Currently, the header and bridge on a harvester are mainly connected by a hook-and-loop connection. After hook-and-loop connection, the header is fixed to the front end of the bridge. To prevent the header from detaching from the bridge during operation, a mushroom head welded to the header is usually used for secondary clamping. In the traditional case, the mushroom head is welded to the header. During the hook-and-loop connection process, the mushroom head usually hits the front of the bridge, causing deformation of the front of the bridge and ultimately affecting the normal operation of the harvester. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a harvester header locking device that can prevent the mushroom head from colliding with the front of the bridge during the process of the header being attached to the bridge, thus ensuring the safe and stable operation of the harvester and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a harvester header locking device, comprising a base plate, a magnetic suction assembly, a suction cup, a fixing bracket, a compression spring, and a mushroom head;

[0006] The base plate is fixed on the cutting table, the magnetic suction assembly is installed on the base plate, one side of the fixed bracket is fixedly connected to the base plate, the mushroom head passes through the fixed bracket, a suction cup is installed at the stem end of the mushroom head, and a compression spring is installed between the fixed bracket and the head end of the mushroom head.

[0007] The magnetic suction assembly achieves adsorption and separation of the suction cup by magnetizing and demagnetizing, thereby controlling the mushroom head to move laterally within the fixed bracket, realizing the separation and locking of the cutting platform and the bridge.

[0008] As a preferred embodiment of this utility model, the magnetic chuck assembly includes a magnetizer, a fixed base, a telescopic rod, a magnetic head, a power cord, and a contact switch;

[0009] The fixed base is installed on the surface of the base plate. One end of the magnetizer is connected to the telescopic rod. The magnetic head is fixed to the end of the telescopic rod and corresponds to the position of the suction cup. One end of the power cord is connected to the magnetizer and the other end is connected to the contact switch. The contact switch is fixed on the cutting table.

[0010] As a preferred embodiment of this utility model, the fixed base is provided with bolt connection holes evenly distributed around its perimeter, and the fixed base is detachably connected to the base plate by bolts passing through the bolt connection holes.

[0011] In a preferred embodiment of this invention, the telescopic rod, magnetic head, suction cup, and mushroom head are located on the same axis.

[0012] In a preferred embodiment of this invention, the magnetic attraction force between the magnetic head and the suction cup in the magnetic chuck assembly is greater than the compression force of the compression spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the harvester header locking device has a compact structure and reasonable design. It controls the magnetization and demagnetization of the magnetic head through the magnetizer in the magnetic suction assembly, thereby controlling the adsorption and separation of the magnetic head and the suction cup at the end of the mushroom head rod. This allows the mushroom head to flexibly separate and lock between the header and the bridge, avoiding deformation of the bridge front caused by the impact between the mushroom head and the bridge front during harvester operation, and ensuring the normal operation of the harvester.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a harvester header locking device, including a base plate 1, a magnetic suction assembly 2, a suction cup 3, a fixing bracket 4, a compression spring 5, and a mushroom head 6;

[0021] The base plate 1 is fixed on the cutting table, the magnetic suction assembly 2 is installed on the base plate 1, one side of the fixed bracket 4 is fixedly connected to the base plate 1, the mushroom head 6 passes through the fixed bracket 4, and the mushroom head 6 can slide on the fixed bracket 4. The mushroom head 6 includes a rod segment and a head. A suction cup 3 is installed at the rod end of the mushroom head 6. A compression spring 5 is installed between the fixed bracket 4 and the head end of the mushroom head 6. The compression spring 5 is sleeved on the outer side of the mushroom head 6.

[0022] The magnetic chuck assembly 2 includes a magnetizer 2-1, a fixed base 2-2, a telescopic rod 2-3, a magnetic head 2-4, a power cord 2-5, and a contact switch 2-6;

[0023] The fixed base 2-2 is installed on the surface of the base plate 1. One end of the magnetizer 2-1 is connected to the telescopic rod 2-3. The magnetic head 2-4 is fixed to the end of the telescopic rod 2-3, and the magnetic head 2-4 corresponds to the position of the suction cup 3. One end of the power cord 2-5 is connected to the magnetizer 2-1, and the other end is connected to the contact switch 2-6. The contact switch 2-6 is fixed on the cutting table. The magnetic suction assembly 2 achieves adsorption and separation of the suction cup 3 by magnetizing and demagnetizing the magnetic head 2-4, thereby controlling the mushroom head 6 to move laterally within the fixed bracket 4, realizing the separation and locking of the cutting table and the bridge.

[0024] To facilitate the installation and removal of the magnetic chuck assembly 2, bolt connection holes are evenly distributed around the fixed base 2-2. The fixed base 2-2 is detachably connected to the base plate 1 by bolts passing through the bolt connection holes.

[0025] To ensure the linearity of the movement of the mushroom head 6, the telescopic rod 2-3, the magnetic head 2-4, the suction cup 3, and the mushroom head 6 are located on the same axis.

[0026] In order to ensure that the magnetic head 2-4 can firmly attach to the suction cup 3, the magnetic attraction between the magnetic head 2-4 and the suction cup 3 in the magnetic chuck assembly 2 is greater than the compression force of the compression spring 5.

[0027] After the cutting platform and the bridge are successfully connected, the driver touches the contact switch 2-6. The contact switch 2-6 sends an electrical signal, which is transmitted to the magnetizer 2-1 through the power line 2-5. The magnetizer 2-1 sends a signal to the magnetic head 2-4, causing the magnetic head 2-4 to demagnetize. After the magnetic head 2-4 is demagnetized, it disengages from the suction cup 3. The mushroom head 6 extends into the bridge locking buckle under the action of the compression spring 5, thereby locking the cutting platform and the bridge.

[0028] When it is necessary to separate the bridge from the cutting table, simply manually trigger the contact switch 2-6 again. The magnetizer 2-1 magnetizes the magnetic head 2-4, and the magnetic head 2-4 is attracted to the suction cup 3, causing the mushroom head 6 to move backward, thus canceling the locking state between the cutting table and the bridge.

[0029] Compared with traditional cutting platform locking devices, this utility model has the advantages of simple structure, convenient installation and small size. During operation, it can avoid deformation of the front of the bridge caused by the impact between the mushroom head and the front of the bridge.
