Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seed box that facilitates the observation of the remaining seed material. Background Technology

[0002] During agricultural sowing operations, real-time monitoring of the remaining seed material in the seed box is crucial for ensuring operational continuity and preventing missed sowing. Currently, agricultural machinery seed boxes typically have transparent observation windows on the side walls of the box so that drivers or operators can visually check the height of the seed material inside. However, agricultural operating environments are usually harsh, accompanied by large amounts of dust, mud splashing, and stone ricochets.

[0003] Most existing seed box observation windows are directly exposed on the outside of the box, lacking effective shielding and protection measures. This open structure makes the observation windows easily obscured by splashing mud, making it impossible for operators to see the internal situation, or they may break and be damaged when hit by hard objects. This not only increases maintenance costs, but may also cause the seed material to become damp and deteriorate due to seal failure, seriously affecting the normal use of the equipment and operating efficiency.

[0004] Therefore, this utility model proposes a seed box that facilitates the observation of the remaining seed material to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology, the observation components of the seed box are exposed to the outside for a long time, which makes observation inconvenient due to mud and dirt, and is easily damaged by external impact, resulting in short service life and high maintenance costs. The present invention aims to provide a seed box with an improved structure that can effectively solve the above problems and facilitate the observation of the remaining seed material.

[0006] This utility model provides a seed box for easy observation of the remaining seed material, comprising: a box body, a box cover rotatably connected to the top of the box body, a discharge port located at the bottom of the box body, and an observation window located on the side wall of the box body; and a protective mechanism located on the outer wall of the box body and at the observation window.

[0007] The protective mechanism mainly consists of a protective plate rotatably connected to the outer wall of the box, a fixed plate fixedly connected to the outer wall of the box, a limiting post slidably connected to the outer wall of the protective plate, and a spring sleeved on the outer wall of the limiting post.

[0008] Furthermore, the protective plate, the fixing plate, and the limiting post are combined through a specific mechanical linkage. The protective plate is located above the observation window and can be flipped down to cover the observation window. The fixing plate is located below the observation window. Under the elastic force of the spring, the bottom end of the limiting post can be inserted into the fixing plate, thereby locking the protective plate in the protective position that blocks the observation window.

[0009] Preferably, a guide block is fixedly connected to the outer wall of the protective plate, the limiting post passes through the guide block and forms a sliding connection with its inner wall, a stop post is fixedly sleeved on the outer wall of the limiting post, one end of the spring abuts against the stop post and the other end abuts against the guide block. Through this structural cooperation, the spring can always apply a reset thrust to the limiting post to make it slide downward.

[0010] Preferably, the upper surface of the fixing plate is provided with a limiting blind hole that is adapted to the limiting post. The limiting blind hole is located at the position corresponding to the bottom end of the limiting post, and is used to accommodate the bottom end of the limiting post when it is inserted in the protective state. This mechanical plugging method restricts the swing of the protective plate and ensures a stable connection.

[0011] Preferably, a pull ring is fixedly connected to the end of the limiting post away from the fixing plate. The pull ring is larger than the diameter of the limiting post and is located at the top end of the limiting post to facilitate the operator to hook the limiting post with their finger and pull it to unlock it.

[0012] Preferably, the observation window is made of transparent tempered glass, which has high light transmittance and impact resistance. The observation window is embedded in the side wall of the box and sealed to provide a certain degree of self-protection while ensuring a clear field of view.

[0013] Preferably, the inner bottom surface of the box is designed as a funnel-shaped structure, and the discharge port is located at the lowest point of the funnel-shaped bottom surface to guide the seed material to smoothly collect and completely discharge under the action of gravity, avoiding dead corners and material accumulation.

[0014] Preferably, a flexible rubber gasket is provided on the edge of the protective plate facing the observation window. The flexible rubber gasket is used to press the protective plate against the outer wall of the box when the protective plate is closed, thereby enhancing the sealing and dustproof performance between the protective plate and the observation window.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing seed box observation windows are easily broken or blocked by mud and stones splashed in the field due to long-term exposure to the outside by setting a protective mechanism consisting of a protective plate, a limiting post, a spring and a fixing plate on the outside of the observation window. It achieves the effect of effectively shielding and protecting the observation window when not in the observation state, preventing damage to the observation window, ensuring a clear observation field, and extending the service life of the device.

[0016] 2. This utility model solves the problem of the protective plate easily opening or shaking and generating noise during the bumpy operation of agricultural machinery by using the sliding cooperation of the limiting post in the guide block and the elastic abutment of the spring, and the plugging cooperation between the bottom end of the limiting post and the upper limit blind hole of the fixing plate. It achieves the effect of quickly locking or unlocking the protective plate without the aid of tools, which not only ensures the stability of the connection, but also improves the convenience of switching observation modes.

[0017] 3. This utility model solves the problems of traditional seed boxes, such as the need to frequently open the lid to check the remaining seed material, which leads to moisture damage, and the problem of seed material residue accumulation caused by the flat bottom structure, by setting up a transparent tempered glass side wall observation window and a funnel-shaped bottom structure inside the box. It achieves the effect of intuitively monitoring the remaining seed material while keeping the box sealed, and automatically emptying the seed material by using gravity guidance, thereby improving the efficiency of sowing operations.

[0020] 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 protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 This utility model provides a seed box that facilitates the observation of remaining seed material, aiming to solve the structural defects of existing seed box structures that make it inconvenient to intuitively monitor the remaining material inside and that the observation components are easily damaged by collisions or contamination due to long-term exposure.

[0022] like Figure 1 and Figure 2 As shown, the main structure of the seed box, which facilitates observation of the remaining seed material, includes a box body 1 and a box cover 2 rotatably connected to the top of the box body 1. The box body 1 serves as the basic load-bearing component of the entire device and has an internal cavity for containing seed material. A guide slope is provided at the bottom of the box body 1, which can guide the seed material to flow smoothly under the action of gravity. A discharge port 3 is provided at the lowest point of the bottom of the box body 1. The discharge port 3 is used to connect with external seed metering devices and other subsequent operating equipment to discharge the seed material stored in the box body 1. The box cover 2 is rotatably mounted on the upper surface of the box body 1 via a hinge and can be opened or closed relative to the box body 1. When the box cover 2 is open, it is convenient to add seed material into the box body 1.

[0023] An installation slot is provided on one side of the outer wall of the box 1, and an observation window 4 is fixedly connected thereto. The observation window 4 is embedded in the side wall of the box 1, and its position corresponds to the seed material storage area inside the box 1. This allows the operator to directly observe the real-time accumulation height and remaining amount of seed material inside the box 1 through the observation window 4 without opening the box cover 2. In order to prevent the observation window 4 from being broken by external sharp objects or obstructed by mud when not in the observation state, a protective mechanism 5 is also provided on the outer wall of the box 1 where the observation window 4 is installed. The protective mechanism 5 covers the outer area of ​​the observation window 4. Through the cooperation of the mechanical structure, it realizes the shielding protection of the observation window 4 and the function of quick opening. The protective mechanism 5 is mainly composed of a protective plate 502 rotatably connected to the outer wall of the box 1, a fixing plate 504 fixedly connected to the outer wall of the box 1, a limiting post 501 slidably connected to the outer wall of the protective plate 502, and a spring 503 sleeved on the outer wall of the limiting post 501. The components cooperate with each other to form a protective assembly with switchable states.

[0024] The protective plate 502 is rotatably connected to the outer wall of the housing 1 via a top pivot structure and is located above the observation window 4, allowing the protective plate 502 to rotate around the pivot, thus switching between a protective position that obstructs the observation window 4 and an observation position that exposes the observation window 4. Two spaced guide blocks are fixedly connected to the outer wall surface of the protective plate 502 along its length. These two guide blocks have through holes at their centers. A limiting post 501 passes through these through holes and slides against the inner wall of the guide blocks. Under the constraint of the guide block, it can make linear reciprocating motion along the length of the protective plate 502. In order to provide the limit post 501 with an automatic reset elastic force, a stop post is fixedly sleeved on the outer wall of the limit post 501. The spring 503 is sleeved on the rod of the limit post 501 located between the two guide blocks. One end of the spring 503 abuts against the side wall of the stop post, and the other end of the spring 503 abuts against the opposite side wall of one of the guide blocks. Through this abutting cooperation, the spring 503 always applies a thrust to the limit post 501 to make it slide downward.

[0025] Meanwhile, the fixing plate 504 is fixedly installed on the outer wall of the housing 1 and located directly below the observation window 4. A limiting blind hole is opened on the upper surface of the fixing plate 504 corresponding to the bottom end of the limiting post 501. The diameter of the limiting blind hole is adapted to the diameter of the limiting post 501. In the normal protection mode, the protective plate 502 hangs down naturally to block the observation window 4. At this time, the bottom end of the limiting post 501 is pushed by the elastic force of the spring 503 and inserted into the limiting blind hole on the fixing plate 504. By using the plug-in cooperation between the limiting post 501 and the fixing plate 504, the bottom end of the protective plate 502 is locked to the side wall of the housing 1 to prevent the protective plate 502 from swinging at will, thereby ensuring that the protective plate 502 stably covers the front of the observation window 4 and effectively blocks the mud and stones splashed from the outside from damaging the observation window 4.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to facilitate the operator in pulling the limiting post 501 to unlock the device, a pull ring is fixedly connected to the end of the limiting post 501 away from the fixing plate 504, i.e., the top end of the limiting post 501. The outer diameter of the pull ring is designed to be larger than the diameter of the rod of the limiting post 501, so that the operator's fingers can easily hook the pull ring and apply an upward pulling force, thereby overcoming the resistance of the spring 503 and driving the limiting post 501 to slide upward, improving the convenience and labor-saving effect of the operation.

[0027] As another preferred embodiment, in order to ensure that the observation window 4 has sufficient strength and clarity, the material of the observation window 4 is preferably made of transparent tempered glass with high light transmittance and excellent impact resistance. Compared with ordinary glass or plastic materials, transparent tempered glass can not only withstand the lateral pressure generated by the flow of seed material, but also resist accidental external impacts to a certain extent. In addition, its surface hardness is high and it is not easy to be scratched, ensuring long-term visibility. At the same time, the connection between the observation window 4 and the side wall of the box 1 is sealed with sealant or rubber sealing strip to prevent rainwater from seeping into the interior of the box 1 and causing the seed material to become damp and moldy.

[0028] As another preferred embodiment, in order to ensure that the seed material can be completely emptied without leaving any residue, the bottom surface of the box 1 is designed as a funnel-shaped structure, and the discharge port 3 is located at the lowest point of the funnel-shaped bottom surface. This structure utilizes the principle of gravity guidance, so that all the seed material in the box 1 can naturally converge and flow to the discharge port 3 under the action of gravity, avoiding the problem of dead corner accumulation that is easily caused by flat bottom structures, while also reducing the trouble of manually cleaning residual seed material, and improving the efficiency of sowing operations and seed material utilization.

[0029] As a further preferred embodiment, in order to enhance the sealing performance of the protective plate 502 over the observation window 4, a flexible rubber gasket can also be attached to the edge of the protective plate 502 facing the observation window 4. When the protective plate 502 is in a closed protective state, the rubber gasket is pressed against the outer wall of the box 1 around the observation window 4, further preventing fine dust particles from entering the gap between the protective plate 502 and the observation window 4, thereby maintaining the cleanliness of the surface of the observation window 4.

[0030] The working principle of this seed box, which facilitates the observation of remaining seed material, is as follows: When the seed box, which facilitates observation of the remaining seed material, is in normal sowing operation, the protective plate 502 is in a naturally drooping state and covers the outside of the observation window 4. At this time, the spring 503 releases its elastic force between the retaining ring and the guide block. This elastic force continuously pushes the limiting post 501 to slide down along the guide block, so that the bottom end of the limiting post 501 is firmly inserted into the limiting blind hole on the surface of the fixing plate 504. Through this insertion and limiting cooperation, the protective plate 502 is locked on the side wall of the box body 1 and cannot rotate, thereby effectively preventing stones and dirt splashed during the operation from directly hitting the observation window 4 and avoiding damage to the observation window 4 or its surface being covered with dirt.

[0031] When staff need to check the remaining seed material inside box 1, they do not need to open box 2. They only need to pull the pull ring at the top of the limiting post 501 to lift it upwards, overcoming the resistance of spring 503 and causing the limiting post 501 to slide upwards along the guide block. When the bottom of the limiting post 501 is completely disengaged from the limiting blind hole on the fixing plate 504, the lock between the protective plate 502 and the fixing plate 504 is released. At this time, staff can rotate the protective plate 502 to flip it upwards, fully exposing the observation window 4. Through the transparent tempered glass observation window 4, staff can clearly see the stacking height of the seed material inside box 1, thereby accurately determining whether replenishment is needed.

[0032] After observation, the staff rotated the protective plate 502 downwards to reset it, so that it covered the observation window 4 again, and adjusted its position so that the limiting post 501 was aligned with the limiting blind hole on the fixing plate 504. Then, the pull ring was released, and the limiting post 501 quickly popped down and inserted into the limiting blind hole under the reset force of the spring 503, thus re-fixing and locking the protective plate 502. The whole operation process is simple and quick. Through the coordinated action of the various components of the protective mechanism 5, the safety of the observation window 4 in harsh working environments is ensured, and the convenience of observing the remaining amount of seed material is not affected. This effectively solves the problem of easy damage to the observation components and inconvenience of observation in the existing technology.

[0033] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
