Description

Technical Field

[0001] This utility model specifically relates to a bulk grain weighing bin. Background Technology

[0002] Existing agricultural bulk grain scales are mostly used for measuring granular raw materials, such as grains. The outlet of the hopper is relatively small, so the sidewalls of the hopper are at a certain angle to the horizontal. This results in significant impact and friction on the conical hopper sidewalls during the material's descent due to its high speed and weight. To extend the hopper's lifespan, the thickness of the inclined sidewalls is usually increased, or linings are added, such as polyurethane linings. However, the principle is similar to increasing the lining thickness; the friction between the material and the sidewalls during descent is not effectively reduced.

[0003] A Chinese patent application with patent number CN202223133969.5, entitled "A Bulk Grain Weighing Bin," discloses "a bulk grain weighing bin, comprising a bin body, wherein the bin body has an inlet and an outlet, and the bin body is hopper-shaped, characterized in that: a plurality of horizontally arranged buffer rods are provided on the inner wall of the bin body, and the plurality of buffer rods are arranged at intervals with their lengths gradually decreasing towards the outlet." Figure 3 It is known that a groove is formed between the buffer rod and the inner wall of the silo body, which makes it easy for impurities to accumulate, affecting the quality of the bulk grain and the accuracy of weighing. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a bulk grain scale hopper that reduces the contact area between the material and the side wall, while also slowing down the falling speed of the material on the side wall and reducing the friction between the material and the side wall, with a long service life and high weighing accuracy.

[0005] To address the above problems, the following technical solution is provided: A bulk grain weighing hopper includes a hopper body with an inlet and an outlet. The hopper body is bucket-shaped, and the inner wall of the hopper body is provided with several buffer plates. The buffer plates are spaced apart and gradually decrease in length towards the outlet. The top surface of each buffer plate is a buffer surface that slopes downward towards the outlet. The angle between the direction of the buffer surface towards the inlet and the inner wall of the hopper body is an obtuse angle. A buffer pad is connected to one end of each buffer plate facing the outlet, and the buffer pad has several buffer protrusions.

[0006] In the above structure, by setting buffer plates at certain intervals on the inner wall of the silo body, the falling path of the material on the inner wall is changed. When the material encounters resistance during its descent, it will jump down the side wall, thus reducing the contact area between the material and the side wall. Simultaneously, by setting several buffer protrusions, the falling speed of the material on the inner wall is also slowed down, thereby reducing the friction between the material and the inner wall and extending the service life of the silo body. This method has a significant effect in practical use, effectively extending the service life of this invention. By making the angle between the buffer plate and the inner wall of the silo body obtuse, the connection is smoother, avoiding the accumulation of debris or dust, improving the quality of material discharge, and enhancing the accuracy of weighing. The buffer pads provide cushioning and shock absorption during material fall, further reducing the impact force on the inner wall and lowering the falling speed of the material.

[0007] The present invention is further configured such that the buffer plate is welded to the main body of the silo.

[0008] By adopting the above structure, the structural strength between the buffer plate and the main body of the silo can be improved, thereby improving the robustness and reliability of this utility model.

[0009] The present invention is further configured such that the end of the buffer pad that is connected to the buffer plate is provided with a T-shaped strip with a T-shaped cross section, and the buffer plate is provided with a T-shaped groove that slides and engages with the T-shaped strip.

[0010] The above structure facilitates the installation of the buffer point and makes it easy to replace the buffer pad after it is worn, thereby improving the ease of installation and making it easier for users to maintain.

[0011] The present invention is further configured such that two sets of T-shaped strips and T-shaped grooves are provided correspondingly.

[0012] By adopting the above structure, the connection strength between the buffer pad and the buffer plate can be further improved, thereby enhancing the stability of the buffer of this utility model.

[0013] The present invention is further configured such that the buffer pad includes a fixed end connected to the buffer plate and a buffer end extending toward the discharge port relative to the buffer plate, the buffer protrusion is disposed on the outer end face of the buffer end, and the buffer end is spaced apart from the inner wall of the hopper body to form a buffer zone.

[0014] In the above structure, the shock resistance of the buffer pad can be improved by setting a buffer zone, thereby improving the buffering effect of this utility model.

[0015] The present invention is further configured such that the buffer end is provided with an abutment strip located within the buffer zone.

[0016] In the above structure, by setting the abutment strip, when the buffer pad is subjected to buffering force, it abuts against the inner wall of the hopper body and plays a supporting role, thereby further improving the stress strength of the buffer pad and improving the reliability of this utility model.

[0017] The present invention is further configured such that the buffer pad is made of rubber.

[0018] The above structure can improve the cushioning capacity of the cushioning pad. Attached Figure Description

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] like Figures 1 to 5The illustrated bulk grain weighing hopper includes a hopper body 1, which has an inlet 11 and an outlet 12. The hopper body 1 is bucket-shaped, and the inner wall of the hopper body 1 is provided with several buffer plates 2. The buffer plates 2 are arranged with their lengths gradually decreasing and spaced apart towards the outlet 12. The top surface of the buffer plate 2 is a buffer surface 21 that is inclined downward towards the outlet 12. The angle between the direction of the buffer surface 21 towards the inlet 11 and the inner wall of the hopper body 1 is an obtuse angle. A buffer pad 3 is connected to one end of the buffer plate 2 facing the outlet 12. The buffer pad 3 has several buffer protrusions 31.

[0028] In the above structure, by setting buffer plates 2 at certain intervals on the inner wall of the silo body 1, the falling path of the material on the inner wall is changed. When the material encounters resistance during its descent, it will jump down the side wall, thus reducing the contact area between the material and the side wall. Simultaneously, by setting several buffer protrusions 31, the falling speed of the material on the inner wall is also slowed down, thereby reducing the friction between the material and the inner wall and extending the service life of the silo body 1. This method has a significant effect in practical use, effectively extending the service life of this utility model. By making the angle between the buffer plate 2 and the inner wall of the silo body 1 an obtuse angle, the connection is smoother, avoiding the accumulation of debris or dust, improving the quality of material discharge, and enhancing the accuracy of weighing. The buffer pad 3 acts as a buffer and shock absorber when the material falls, further reducing the impact force on the inner wall and lowering the falling speed of the material.

[0029] The present invention is further configured such that the buffer plate 2 is welded to the silo body 1.

[0030] By adopting the above structure, the structural strength between the buffer plate 2 and the hopper body 1 can be improved, thereby improving the robustness and reliability of this utility model.

[0031] The present invention is further configured such that the end of the buffer pad 3 that is connected to the buffer plate 2 is provided with a T-shaped strip 32 with a T-shaped cross section, and the buffer plate 2 is provided with a T-shaped groove 22 that slides and engages with the T-shaped strip 32.

[0032] The above structure facilitates the installation of the buffer point and makes it easy to replace the buffer pad 3 after it is worn, thereby improving the ease of installation of this utility model and making it easier for users to maintain.

[0033] The present invention is further configured such that two sets of T-shaped bars 32 and T-shaped grooves 22 are provided correspondingly.

[0034] By adopting the above structure, the connection strength between the buffer pad 3 and the buffer plate 2 can be further improved, thereby enhancing the stability of the buffer of this utility model.

[0035] The present invention is further configured such that the buffer pad 3 includes a fixed end 33 connected to the buffer plate 2 and a buffer end 34 extending relative to the buffer plate 2 toward the discharge port 12. The buffer protrusion 31 is disposed on the outer end face of the buffer end 34. The buffer end 34 is spaced apart from the inner wall of the hopper body 1 to form a buffer zone 35.

[0036] In the above structure, by setting the buffer zone 35, the impact resistance of the buffer pad 3 can be improved, thereby improving the buffering effect of this utility model.

[0037] The present invention is further configured such that the buffer end 34 is provided with an abutment strip 36 located within the buffer zone 35.

[0038] In the above structure, by setting the abutment strip 36, when the buffer pad 3 is subjected to buffering force, it abuts against the inner wall of the hopper body 1 to play a supporting role, thereby further improving the stress strength of the buffer pad 3 and improving the reliability of this utility model.

[0039] The present invention is further configured such that the buffer pad 3 is made of rubber.

[0040] The above structure can improve the cushioning capacity of the cushioning pad 3.

[0041] In this embodiment, a wear-resistant layer can be bonded to the buffer end 34.

[0042] In the above structure, the wear-resistant layer improves the wear resistance of the buffer end 34, thereby protecting it and extending its service life. The wear-resistant layer is made of polytetrafluoroethylene, which further enhances its wear resistance.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
