[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1-4 This utility model provides a hopper for a corn planter, including a feed inlet 1, a through groove 101 fixedly connected to the bottom of the feed inlet 1, a first circular groove hole opened at one corner of the feed inlet 1, and a locking component 2 provided on one side of the feed inlet 1.

[0024] The locking assembly 2 includes a cylinder 202 detachably connected to a first circular slot. Maintenance doors 201 are installed on the surfaces of several cylinders 202. Second circular holes are symmetrically opened within the first circular slot. Two sliding rods 203 are slidably connected inside the cylinder 202. An L-shaped locking rod 204 is fixedly connected to the surface of each sliding rod 203. A limit block 205 is fixedly connected to one end of each sliding rod 203. A through groove 101 is provided at the bottom of the feed inlet 1 to connect the feed inlet 1 to the unloading mechanism, serving as a connecting channel. First circular slots are opened at the corners of one side of the feed inlet 1, allowing one side of the feed inlet 1 to move freely. A maintenance door 201 is provided. At the position of the first circular slot corresponding to the maintenance door 201, a cylinder 202 is provided. A slide rod 203 is slidably connected inside the cylinder 202. The slide rods 203 are symmetrically arranged inside the cylinder 202. An L-shaped locking rod 204 is fixedly connected to the side of the two slide rods 203 near the first circular slot. A first circular hole is symmetrically opened in the first circular slot. Limiting blocks 205 are fixedly connected to both ends of the two slide rods 203. The limiting blocks 205 play the role of limiting the slide rods 203 to prevent the slide rods 203 from moving excessively and detaching from the cylinder 202, which would cause damage to the device.

[0025] During operation, when it is necessary to open the maintenance door 201 to repair or clean the inside of the feed inlet 1, a squeezing force is applied to the limiting blocks 205 on both sides of the cylinder 202. When the limiting blocks 205 move inward, they can drive the sliding rod 203 to slide along the axis of the cylinder 202 inside the cylinder 202. Since the cylinder 202 is rigidly connected to the L-shaped locking rod 204 on one side, when the sliding rod 203 moves under the action of the limiting blocks 205, it can drive the L-shaped locking rod 204 to move synchronously. At this time, the L-shaped locking rod 204 can disengage from the first circular hole in the first circular slot, and the maintenance door 201 is unlocked. After the inspection or cleaning is completed, when it is necessary to close the maintenance door 201, the squeezing force on the limiting blocks 205 is released, and the sliding rod 203 can drive the L-shaped locking rod 204 to re-lock into the first circular hole, realizing the automatic locking of the maintenance door 201, ensuring the sealing performance of the feed inlet 1, and preventing seed leakage during operation.

[0026] Furthermore, such as Figure 1 and Figure 4As shown, a foldable waterproof plate 3 is installed on the top of the feed inlet 1. A handle 301 is fixedly connected to one side of the foldable waterproof plate 3. The purpose of the foldable waterproof plate 3 is to prevent mud, rainwater or debris from splashing into the feed inlet 1 after the material feeding operation is completed. The operator can unfold or fold the foldable waterproof plate 3 to cover or store it by holding the handle 301. When unfolded, it can completely cover the top opening of the feed inlet 1 to form effective protection. When folded, it does not occupy extra space and does not affect subsequent feeding, maintenance and other operations. The operation is flexible and convenient.

[0027] Furthermore, such as Figure 3 As shown, a connecting disc 207 is fixedly connected to the opposite face of each of the two sliding rods 203. A spring 206 is fixedly connected between the two connecting discs 207. A connecting disc 207 is fixedly connected to the opposite face of each of the two sliding rods 203. A spring 206 is fixedly connected between the two discs. When the pressure on the limiting block 205 is released, the spring 206 will release its elasticity. Through the connecting disc 207, the two sliding rods 203 will move synchronously in opposite directions along the axial direction of the cylinder 202, thereby driving the L-shaped locking rod 204 to accurately engage in the first circular hole, realizing the automatic and tight locking of the maintenance door 201.

[0028] Furthermore, such as Figure 4 As shown, an anti-impact baffle 102 is installed inside the feed inlet 1. When seeds need to be put into the feed inlet 1, if the seeds fall directly into the inlet, they are prone to collision with the inner wall of the feed inlet 1, which may cause the seeds to break. The inclined anti-impact baffle 102 can effectively catch the falling seeds and provide a buffer for the seeds through its own inclined surface, which greatly reduces the impact force when the seeds fall. At the same time, the design of the inclined angle of the anti-impact baffle 102 allows the seeds to slide smoothly along the surface of the anti-impact baffle 102 and finally enter the feed inlet 1 smoothly, which not only avoids seed breakage but also ensures the continuity of seed conveying.

[0029] Furthermore, such as Figure 1 As shown, a transparent acrylic plate is fixedly connected to the center of the maintenance door 201. The design of the transparent acrylic plate allows operators to directly observe the seed status or component operation inside the feed inlet 1 through the transparent acrylic plate, so as to grasp the internal information without frequently opening the maintenance door 201, thus improving the convenience of operation.

[0030] Furthermore, such as Figure 3As shown, the L-shaped locking rod 204 matches the size of the first circular hole, and the outer diameter of the L-shaped locking rod 204 matches the inner diameter of the first circular hole. When the L-shaped locking rod 204 is inserted into the first circular hole, the maintenance door 201 will not become loose due to excessive gap, nor will it fail to be fully inserted due to insufficient size. This provides a basic guarantee for the stable locking of the maintenance door 201 and further enhances the sealing performance and safety of the feed inlet 1.

[0031] Working principle: During operation, a transparent acrylic plate is fixed to the center of the maintenance door 201. The design of the transparent acrylic plate allows observation of the seed status or component operation inside the feed inlet 1, enabling access to internal information without frequent opening of the maintenance door 201, thus improving operational convenience. When it is necessary to open the maintenance door 201 for maintenance or cleaning of the feed inlet 1, a pressing force is applied to the limiting blocks 205 on both sides of the cylinder 202. When the limiting blocks 205 move inward, they can drive the sliding rod 203 to slide along the axis of the cylinder 202 inside the cylinder 202. The L-shaped locking rod 204 on one side is rigidly connected. When the sliding rod 203 moves under the action of the limiting block 205, it can drive the L-shaped locking rod 204 to move synchronously. At this time, the L-shaped locking rod 204 can disengage from the first circular hole in the first circular slot. At this time, the maintenance door 201 achieves the purpose of unlocking. After maintenance or cleaning, when it is necessary to close the maintenance door 201, the squeezing force on the limiting block 205 is released. A connecting disc 207 is fixedly connected to the opposite face of each of the two sliding rods 203, and a spring 206 is fixedly connected between the two discs. When the squeezing force on the limiting block 205 is released, the spring 207... The elasticity of the 6-axis releases the sliding rod 203, which in turn drives the L-shaped locking rod 204 to re-engage into the first circular hole, thus automatically locking the maintenance door 201. The outer diameter of the L-shaped locking rod 204 matches the inner diameter of the first circular hole, providing a basic guarantee for the stable locking of the maintenance door 201. This further enhances the sealing performance and safety of the feed inlet 1, ensuring its sealing performance and preventing seed leakage during operation. The anti-impact baffle 102 installed inside the feed inlet 1 provides cushioning for the seeds through its inclined surface, significantly reducing the impact force when the seeds fall. The tilted design of the impact baffle 102 allows the seeds to slide smoothly along the surface of the impact baffle 102 and eventually enter the feed inlet 1 smoothly. This not only avoids seed damage but also ensures the continuity of seed delivery. To prevent mud, rainwater, or debris from splashing into the feed inlet 1 after the feeding operation is completed, the operator can unfold or fold the foldable waterproof plate 3 by holding the handle 301. When unfolded, it can completely cover the top opening of the feed inlet 1, forming effective protection. When folded, it does not occupy extra space and does not affect subsequent feeding, maintenance, or other operations. The operation is flexible and convenient.
