Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of peeling roller spring installation for harvesters, and more specifically, to a peeling roller spring installation device for corn harvesters. Background Technology
[0002] Corn harvesters, as key equipment in agricultural production, are widely used in the corn harvesting process. The hulling roller, a crucial tool for hulling in the harvester, directly affects the quality and efficiency of corn hulling. The adjustment of the hulling roller gap relies on the hulling roller spring. When the hulling roller is damaged during use and needs replacement, both the hulling roller and its spring must be removed before a new one can be installed. However, after removing the hulling roller spring, reinstalling it in its natural length on the harvester presents difficulties and time-consuming operations. Utility Model Content
[0003] The purpose of this utility model is to provide a corn harvester peeling roller spring installation device, which addresses the shortcomings of the existing technology and solves the problems mentioned in the background.
[0004] The technical solution of this utility model is implemented as follows:
[0005] The utility model provides a corn harvester peeling roller spring mounting device, including a base, a first limiting block at one end of the base, a fixing structure for fixing the mandrel on the first limiting block, a second limiting block at the other end of the base, a limiting groove on the second limiting block, the mandrel being slidably disposed in the limiting groove, and a pushing structure on the first limiting block for pushing the mandrel to move along its axial direction.
[0006] In some technical solutions of this utility model, the fixing structure includes a mounting hole opened on the side wall of the first limiting block, a push rod is installed in the mounting hole, and the pushing structure is connected to the push rod in a transmission manner.
[0007] In some technical solutions of this utility model, the pushing structure includes a first nut installed in the mounting hole, and a clamping bolt threadedly connected to the first nut is provided therein, and the clamping bolt is fixedly connected to the push rod.
[0008] In some technical solutions of this utility model, a limiting hole is opened on the end face of the mandrel, and a part of the push rod is embedded in the limiting hole.
[0009] In some technical solutions of this utility model, the limiting groove is U-shaped.
[0010] In some technical solutions of this utility model, the side wall of the first limiting block has two first through holes, each of which is provided with a first fixing bolt, and the end face of the base is provided with a first internal thread hole that is threadedly connected to the first fixing bolt.
[0011] In some technical solutions of this utility model, the side wall of the second limiting block has two second through holes, each of which is provided with a second fixing bolt, and the end face of the base is provided with a second internal thread hole that is threadedly connected to the second fixing bolt.
[0012] Compared to existing technologies, this invention has at least the following advantages or beneficial effects: the top rod and clamping bolt are integrally formed, and the first nut is fixed in the mounting hole by welding, improving the stability of the structure during operation. When adjusting the peeling roller spring, rotating the clamping bolt passes through the welded nut and contacts the peeling roller spring, changing the length of the clamping bolt relative to the welded nut, thereby adjusting the compression of the peeling roller spring and controlling the spring length. Adjusting the compression of the peeling roller spring through the above structure can speed up the adjustment process and can be adjusted according to the actual amount, making it easy to operate.

The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0019] Example
[0020] This utility model provides an installation device for the peeling roller spring 9 of a corn harvester, such as... Figures 1-3 As shown, the system includes a base 1, which is made of steel plate. A first limiting block 2 is provided at one end of the base 1, perpendicular to the base 1, and the two are detachably connected by bolts. The first limiting block 2 has a fixing structure for fixing the mandrel 10; the other end of the base 1 has a second limiting block 3, which has a limiting groove. The mandrel 10 is slidably disposed within the limiting groove. The first limiting block 2 has a pushing structure for pushing the mandrel 10 to move along its axial direction.
[0021] Preferably, the structure of the peeling roller spring 9 is shown in the figure. The peeling roller spring 9 includes a spring core, a front washer, a nut, a spring, and a rear washer. The front end of the spring core has threads, and the spring passes through the spring core. The nut is screwed onto the threaded end of the spring core. At the front end of the spring, the front washer is placed on the front end of the spring core and contacts the threaded shaft end. The rear washer is placed on the rear end of the spring core and contacts the rear end of the spring. When used in a harvester, one of the front washer and the nut is used to limit the axial position of the peeling roller spring 9, and the other nut is used to compress the spring, thereby adjusting the gap size of the peeling rollers on the harvester.
[0022] In some technical solutions of this utility model, the fixing structure includes a mounting hole opened on the side wall of the first limiting block 2, a push rod 11 is installed in the mounting hole, and the pushing structure is connected to the push rod 11 in a transmission manner.
[0023] In some technical solutions of this utility model, the pushing structure includes a first nut 4 installed in the mounting hole. The first nut 4 has a clamping bolt 5 threadedly connected to it, and the clamping bolt 5 is fixedly connected to the push rod 11. The push rod 11 and the clamping bolt are integrally formed. The first nut 4 is fixed in the mounting hole by welding, improving the stability of the structure during operation. When adjusting the peeling spring 9, the clamping bolt 5 is rotated to pass through the welded nut and contact the peeling spring 9, changing the length of the clamping bolt 5 relative to the welded nut, thereby adjusting the compression of the peeling spring 9 and controlling the spring length. Adjusting the compression of the peeling spring 9 through the above structure can speed up the adjustment process and can be adjusted according to the actual amount, making it easy to operate.
[0024] In some technical solutions of this utility model, a limiting hole is provided on the end face of the mandrel 10, and a portion of the push rod 11 is embedded in the limiting hole. Inserting a portion of the push rod 11 into the limiting hole located on the end face of the mandrel 10 can prevent the mandrel 10 from disengaging from the clamping bolt 5 when adjusting the compression of the peeling roller spring 9, thus preventing the problem of the above structure failing to adjust the peeling roller spring 9.
[0025] In some technical solutions of this utility model, the limiting groove is U-shaped. The two vertical sections of the limiting groove can prevent the mandrel 10 from rolling in the limiting groove, thereby limiting the mandrel 10 and allowing it to move along its axial direction.
[0026] In some technical solutions of this utility model, the first limiting block 2 and the base 1 are fixed in the following way: Firstly, two first through holes are opened on the side wall of the first limiting block 2, and a first fixing bolt 6 is provided in each of the first through holes. A first internal thread hole is opened on the end face of the base 1, which is threaded to the first fixing bolt 6. The two first fixing bolts 6 can prevent the base 1 and the first limiting block 2 from separating, thereby improving the stability between the base 1 and the first limiting block 2.
[0027] In some technical solutions of this utility model, the second limiting block 3 is fixed to the base 1 in the following way: two second through holes are opened on the side wall of the second limiting block 3, and a second fixing bolt 7 is provided in each of the second through holes. A second internal thread hole is opened on the end face of the base 1, which is threaded to the second fixing bolt 7. The two second fixing bolts 7 can prevent the base 1 and the second limiting block 3 from separating, improve the stability between the base 1 and the second limiting block 3, and ensure that when the above structure is installed on the peeling spring 9 structure, no malfunction will occur that will affect the installation of the peeling spring 9.
[0028] The working principle of this device for installing the peeling roller spring 9 is as follows: the spindle 10 of the peeling roller spring 9 contacts the clamping bolt 5, and the push rod 11 connected to the clamping bolt 5 is embedded in the spindle 10; the rear end washer contacts the U-shaped groove of the second limiting block 3; then the clamping bolt 5 is tightened, and the clamping bolt 5 pushes the spindle 10 to move backward. Since the front end of the spring is restricted from moving forward by a nut, and the rear end of the spring is also restricted from moving by a washer, the movement of the spindle 10 compresses the spring, and the spindle 10 gradually moves out of the U-shaped groove. When the compression meets the installation requirements, the peeling roller spring 9 can be installed at the corresponding position on the harvester.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
