Abstract
Description
Technical Field
[0001] This utility model relates to the field of corn planting technology, specifically to a corn harvester. Background Technology
[0002] The corn puller is an important component of a corn harvester. Its main function is to effectively remove weeds and stalks from the field while harvesting corn, thereby improving harvesting efficiency and quality. This device uses a chain and gear drive, employing a serrated puller to clamp and separate weeds and stalks, achieving the purpose of cutting both corn and weeds.
[0003] In the process of developing this application, the following problems were found with the technology: the existing corn pullers cannot remove shorter roots in the field during use, so the corn stalks still need to be removed by the grower. However, manually removing corn stalks is labor-intensive, which increases the cost of corn planting.
[0004] Therefore, a rice-pulling device is proposed. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that existing corn stalk pullers cannot remove shorter roots in the field, requiring growers to remove the roots of corn stalks later. However, manually removing corn stalks is labor-intensive and increases the cost of corn planting. This utility model provides a corn stalk puller.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A harvester includes a V-shaped bracket with a slot on its upper surface. The inner walls of the slot on both sides of the V-shaped bracket have through holes. The two sets of through holes of the V-shaped bracket are rotatably connected to a harvesting mechanism for quickly removing multiple corn stalks from the ground. The harvesting mechanism has a slot inside, and a limit mechanism is installed inside the slot.
[0008] Furthermore, the harvesting mechanism includes a rotating rod and a second connecting rod. The rotating rod is rotatably connected to the two sets of through holes in the V-shaped bracket. A first connecting rod is provided on the back of the rotating rod, and four sets of fixing plates are installed on the front of the rotating rod. A fixing rod is installed on the upper surface of the rotating rod. The second connecting rod is installed on the front of the V-shaped bracket, and four sets of positioning plates are provided on the back of the second connecting rod. The four sets of positioning plates are respectively positioned on the moving path of the four sets of fixing plates. The position of the inner front wall of the V-shaped bracket is located on the moving path of the rotating rod. The positions of the front of the four sets of fixing plates and the front of the rotating rod are parallel, and the positions of the back of the four sets of positioning plates and the inner front wall of the V-shaped bracket are parallel.
[0009] Furthermore, support seats are installed on the lower surface of the V-shaped bracket and the lower surfaces of the four sets of positioning plates.
[0010] Furthermore, the limiting mechanism includes five sets of connecting plates. The front of the rotating rod and the four sets of fixing plates are all provided with slots. The five sets of connecting plates are respectively installed and snapped into the slots of the rotating rod and the four sets of fixing plates. The front of the five sets of connecting plates is provided with racks.
[0011] Furthermore, a rubber pad is adhered to the outer surface of the fixing rod.
[0012] Furthermore, an arc-shaped protective plate is installed on the front of the rotating rod, and the front of the arc-shaped protective plate abuts against the inner wall of the front side of the V-shaped bracket slot. The distance between the outer surface of the arc-shaped protective plate and the rotation axis of the rotating rod is the same as the distance between the inner wall of the front side of the V-shaped bracket slot and the rotation axis of the rotating rod.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model adjusts the position of the movable V-shaped bracket, placing it on the front and rear sides of multiple sets of corn stalks. Then, by pushing the fixing rod, the rotating rod is rotated, pushing multiple sets of fixing plates against the back of multiple sets of positioning plates. This causes the front of the fixing plates to abut against the back of the positioning plates, simultaneously locking the corn stalks between the fixing and positioning plates. Pulling the fixing rod tilts the device backward, causing the fixing and positioning plates to remove the corn stalks accumulated on the ground during this tilting process. This completes the removal of multiple sets of corn stalks in a single operation, reducing subsequent corn planting costs and thus improving the practicality of the device.
[0015] 2. This utility model uses the same distance between the outer surface of the arc-shaped protective plate and the rotation axis of the rotating rod as the distance between the inner wall of the front side of the V-shaped bracket slot and the rotation axis of the rotating rod. This ensures that the outer surface of the arc-shaped protective plate continuously abuts against the inner wall of the front side of the V-shaped bracket slot during the rotation of the rotating rod. Consequently, the arc-shaped protective plate blocks the space between the inner wall of the front side of the V-shaped bracket slot and the rotating rod, thus minimizing the obstruction of the rotating rod by the corn stalk during its rotation, which would affect the normal use of the device.

Therefore, they should not be construed as limitations on this utility model.
[0025] like Figures 1 to 4As shown, a corn stalk puller includes a V-shaped bracket 1. The upper surface of the V-shaped bracket 1 has a slot, and through holes are formed on the inner walls of both sides of the slot. A corn stalk pulling mechanism 2 for quickly removing multiple corn stalks from the ground is rotatably connected to the two sets of through holes in the V-shaped bracket 1. The corn stalk pulling mechanism 2 has a slot inside, and a limiting mechanism 5 is installed inside the slot. Specifically, by rotating the limiting mechanism 5, multiple corn stalks are secured inside the multiple corn stalk pulling mechanisms 2. Then, by pressing the corn stalk pulling mechanism 2 and the V-shaped bracket 1 backward, the multiple corn stalks are moved out of the ground, thus completing the single-time removal of multiple corn stalks, thereby reducing subsequent corn planting costs and improving the practicality of the device.
[0026] like Figures 1 to 4 As shown, the harvesting mechanism 2 includes a rotating rod 206 and a connecting rod 205. The rotating rod 206 is rotatably connected to the two sets of through holes in the V-shaped bracket 1. A connecting rod 202 is provided on the back of the rotating rod 206. Four sets of fixing plates 203 are installed on the front of the rotating rod 206. A fixing rod 201 is installed on the upper surface of the rotating rod 206. The connecting rod 205 is installed on the front of the V-shaped bracket 1. Four sets of positioning plates 204 are provided on the back of the connecting rod 205. The positions of the four positioning plates 204 are respectively set on the moving path of the four sets of fixing plates 203. The position of the inner front wall of the V-shaped bracket 1 is located on the moving path of the rotating rod 206. The positions of the front of the four sets of fixing plates 203 and the front of the rotating rod 206 are parallel. The positions of the back of the four sets of positioning plates 204 and the inner front wall of the V-shaped bracket 1 are parallel.
[0027] Specifically, by adjusting the position of the movable V-shaped bracket 1, the V-shaped bracket 1 is positioned on the front and rear sides of multiple sets of corn stalks. Then, by pushing the fixed rod 201, the rotating rod 206 is rotated, pushing the multiple sets of fixed plates 203 against the back of the multiple sets of positioning plates 204. This allows the front of the multiple sets of fixed plates 203 to abut against the back of the multiple sets of positioning plates 204, while simultaneously clamping the multiple sets of corn stalks between the multiple sets of fixed plates 203 and the multiple sets of positioning plates 204. By pulling the fixed rod 201, the device is tilted to the rear, causing the multiple sets of fixed plates 203 and the multiple sets of positioning plates 204 to remove the multiple sets of corn stalks accumulated in the ground during the tilting process. This completes the removal of multiple sets of corn stalks in a single operation, thereby reducing the subsequent corn planting cost and improving the practicality of the device.
[0028] like Figure 1 and Figure 2As shown, support seats 4 are installed on the lower surface of the V-shaped bracket 1 and the lower surface of the four sets of positioning plates 204. Specifically, by increasing the contact surface between the bottom of the harvesting mechanism 2 and the V-shaped bracket 1 and the ground through multiple sets of support seats 4, the V-shaped bracket 1 and the harvesting mechanism 2 are supported by multiple sets of support seats 4 during use. This avoids the bottom of the V-shaped bracket 1 and the harvesting mechanism 2 from inserting into the ground during subsequent pressing, thus reducing the labor required for workers to move the device and improving its practicality.
[0029] like Figure 1 and Figure 2 As shown, the limiting mechanism 5 includes five sets of connecting plates 501. The rotating rod 206 and four sets of fixing plates 203 all have slots on their front sides. The five sets of connecting plates 501 are respectively installed and locked inside the slots of the rotating rod 206 and the four sets of fixing plates 203. Each of the five sets of connecting plates 501 has a rack 502 on its front side. Specifically, by positioning the racks 502 between the positioning plates 204 and the inner wall of the front side of the V-shaped bracket 1, the racks 502 increase the contact surface between the pulling mechanism 2 and the corn stalk when the fixing plates 203 and the rotating rod 206 clamp the outer end of the corn stalk. This minimizes the movement of the corn stalk when the fixing plates 203 and the rotating rod 206 push it against the inner wall of the front side of the positioning plates 204 and the V-shaped bracket 1, thus improving the stability of the pulling mechanism 2 when pulling the corn stalk.
[0030] like Figure 1 and Figure 2 As shown, a rubber pad 3 is bonded to the outer surface of the fixing rod 201. Specifically, by positioning the rubber pad 3 on the outer surface of the fixing rod 201, the subsequent operator's hands are held on the outer surface of the rubber pad 3 during the operation of the rice pulling mechanism 2. This minimizes the risk of injury or calluses caused by friction between the operator's hands and the fixing rod 201 during prolonged operation of the rice pulling mechanism 2, thereby improving the comfort of the operator when operating the rice pulling mechanism 2.
[0031] like Figures 1 to 4As shown, an arc-shaped protective plate 6 is installed on the front of the rotating rod 206. The front of the arc-shaped protective plate 6 abuts against the inner wall of the front side of the slot of the V-shaped bracket 1. The distance between the outer surface of the arc-shaped protective plate 6 and the rotation axis of the rotating rod 206 is the same as the distance between the inner wall of the front side of the slot of the V-shaped bracket 1 and the rotation axis of the rotating rod 206. Specifically, by ensuring that the distance between the outer surface of the arc-shaped protective plate 6 and the rotation axis of the rotating rod 206 is the same as the distance between the inner wall of the front side of the slot of the V-shaped bracket 1 and the rotation axis of the rotating rod 206, the outer surface of the arc-shaped protective plate 6 continuously abuts against the inner wall of the front side of the slot of the V-shaped bracket 1 during the rotation of the rotating rod 206. This allows the arc-shaped protective plate 6 to block the space between the inner wall of the front side of the slot of the V-shaped bracket 1 and the rotating rod 206, thereby minimizing the obstruction of the rotating rod 206 by the corn stalk during its rotation, which would affect the normal use of the device.
[0032] In summary: By adjusting the position of the movable V-shaped bracket 1, placing it on the front and rear sides of multiple sets of corn stalks, and then pushing the fixing rod 201 to rotate the rotating rod 206, the multiple sets of fixing plates 203 are pushed to abut against the back of the multiple sets of positioning plates 204. This causes the front of the fixing plates 203 to abut against the back of the positioning plates 204, simultaneously securing the multiple sets of corn stalks between the fixing plates 203 and the positioning plates 204. Pulling the fixing rod 201 tilts the device backward, causing the multiple sets of fixing plates 203 and the multiple sets of positioning plates 204 to... 04 During the tilting process, multiple sets of corn stalks accumulated inside the ground are removed, thus completing the removal of multiple sets of corn stalks in a single operation; by positioning multiple sets of racks 502 between multiple sets of positioning plates 204 and the inner front wall of the V-shaped bracket 1, the multiple sets of racks 502 increase the contact surface between the pulling mechanism 2 and the corn stalks when the multiple sets of fixing plates 203 and rotating rods 206 clamp the outer end of the corn stalks, thereby minimizing the movement of the corn stalks when the multiple sets of fixing plates 203 and rotating rods 206 push the corn stalks against the inner front wall of the multiple sets of positioning plates 204 and the V-shaped bracket 1.
[0033] Meanwhile, by ensuring that the distance between the outer surface of the arc-shaped protective plate 6 and the rotation axis of the rotating rod 206 is the same as the distance between the inner wall of the front side of the slot of the V-shaped bracket 1 and the rotation axis of the rotating rod 206, the outer surface of the arc-shaped protective plate 6 continuously abuts against the inner wall of the front side of the slot of the V-shaped bracket 1 during the rotation of the rotating rod 206. This allows the arc-shaped protective plate 6 to shield the space between the inner wall of the front side of the slot of the V-shaped bracket 1 and the rotating rod 206, thereby minimizing the obstruction of the rotating rod 206 by the corn stalk during its rotation, which would otherwise affect the normal use of the device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
