Description

Technical Field

[0001] This utility model belongs to the technical field of grain transfer equipment, and in particular relates to a metering dust suppression hopper and a feeding system for grain dispensing. Background Technology

[0002] Currently, during grain transfer, grain is primarily loaded onto transport vehicles via gravity flow. During loading, impurities and dust from the grain are carried away by the high-speed airflow generated as the grain falls, dispersing into the surrounding space. The fine, light dust settles slowly, causing dust pollution in the loading area, harming the environment and the health of personnel. Furthermore, the weight of the grain cannot be measured during loading, leading to underloading or overloading, requiring vehicles to make repeated trips to weigh the grain, increasing the cost of machinery and labor, resulting in low loading efficiency and higher loading costs. Summary of the Invention

[0003] This utility model provides a metering dust suppression hopper and a feeding system for grain distribution, which overcomes the shortcomings of the existing loading process by adding a metering device and a dust suppression hopper at the outlet.

[0004] One technical solution of this utility model is as follows: A metering dust suppression hopper for grain distribution includes: a metering device and a dust suppression hopper. The metering device is installed above the dust suppression hopper. The metering device includes: a housing, a metering feed pipe, a punch plate, and a pressure sensor. The metering feed pipe is installed at the top of the housing. An inclined slide is provided at the bottom of the metering feed pipe. The punch plate and the pressure sensor are installed inclined inside the housing. The pressure sensor is located below the punch plate. The punch plate is located at the outlet of the slide. A discharge bottom plate is provided at the bottom of the housing. The discharge bottom plate is connected to the feed inlet of the dust suppression hopper.

[0005] Furthermore, the inclination direction of the slide is the same as the inclination direction of the punch plate.

[0006] Furthermore, an arc-shaped door is provided inside the housing, which is used to adjust the size of the outlet of the slide.

[0007] Furthermore, the dust suppression hopper includes: an inlet pipe, a discharge hopper, a fixed bracket, a material blocking valve core, and a spring. The inlet pipe is connected to the discharge bottom plate. The top end of the spring is connected to the inlet pipe, and the bottom end of the spring is connected to the discharge hopper. The top end of the fixed bracket is fixed to the inner wall of the inlet pipe, and the material blocking valve core is fixed to the bottom end of the fixed bracket. The material blocking valve core is located in the discharge port of the discharge hopper.

[0008] Furthermore, the fixed bracket includes a fixed rod, a fixed body, and a connecting rod. The fixed body is located at the center of the feed inlet. Multiple fixed rods are provided on the top of the fixed body, and all of the multiple fixed rods are fixed inside the feed inlet. The connecting rod is rotatably disposed at the bottom of the fixed body, and the bottom of the connecting rod is fixed with a material blocking valve core.

[0009] Furthermore, the width of the material blocking valve core is greater than or equal to the width of the discharge port of the hopper.

[0010] Another technical solution of this utility model is as follows: a feeding system, comprising: a feeding pipe, a control valve, and any of the above-mentioned metering dust suppression hoppers for grain dispensing, wherein the top of the feeding pipe is connected to the grain depot discharge pipe, the control valve is disposed on the feeding pipe, and the bottom of the feeding pipe is connected to the metering feed pipe.

[0011] Furthermore, the control valve includes an actuation gate valve and a manual slide gate valve.

[0012] Furthermore, it also includes a platform installed on the side wall of the grain depot, with the control valve located on the platform and the top of the metering device fixed to the bottom of the platform.

[0013] The beneficial effects of this utility model are as follows: This invention utilizes a weighing device to measure the weight of grain loaded onto trucks, reducing the occurrence of underloading and overloading, avoiding the inconvenience of vehicles having to go back and forth to weigh the grain, reducing the cost of using machinery and labor, improving loading efficiency, and the dust suppression hopper can reduce dust and prevent dust from spreading in the workplace, providing a good working environment for operators.

[0014] This utility model has a simple structure, occupies little height space, and is easy to use. It can both measure the amount of grain dispensed and suppress dust without power, achieving energy conservation, emission reduction, and green loading. Attached Figure Description

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] In one technical solution of this utility model, Figure 1 This is a structural diagram illustrating the specific structure of a metering dust suppression hopper for grain distribution according to this utility model. Figure 1 As shown, this utility model includes: A metering device 4 and a dust suppression hopper 5 are provided. The metering device 4 is installed above the dust suppression hopper 5. The metering device 4 includes a housing 42, a metering feed pipe 41, a punch plate 44, and a pressure sensor 45. The metering feed pipe 41 is installed on the top of the housing 42. An inclined slide 47 is provided at the bottom of the metering feed pipe 41. The punch plate 44 and the pressure sensor 45 are installed inclined inside the housing 42. The pressure sensor 45 is located below the punch plate 44. The punch plate 44 is located at the outlet of the slide 47. A discharge bottom plate 46 is provided at the bottom of the housing 42. The discharge bottom plate 46 is connected to the feed inlet of the dust suppression hopper 5.

[0021] like Figure 2 As shown, the unique fully enclosed buffer mechanical structure of the shell 42 allows the material to be unaffected by process environmental factors such as material flow, vibration, and wind speed during the proportioning process, ensuring continuous, high-precision, and stable operation.

[0022] The inclination direction of the slide 47 is the same as that of the punch plate 44. The punch plate 44 and the pressure sensor 45 are installed at an angle, which reduces the force during measurement, increases the measurement accuracy, and prevents the pressure sensor from being damaged by overload.

[0023] An arc-shaped door 43 is provided inside the housing 42. The arc-shaped door 43 is used to adjust the size of the outlet of the slide 47. By adjusting the size of the outlet of the slide 47 through the arc-shaped door 43, the flow rate of the slide is adjusted, making the material feeding more uniform. The arc-shaped door 43 ensures that the material is fed continuously and uniformly throughout the entire range during the mixing process, and the material is fed smoothly even when the flow rate is low.

[0024] In one embodiment of this utility model, such as Figure 3As shown, the dust suppression hopper 5 includes: an inlet pipe 51, a discharge hopper 52, a fixed bracket, a material blocking valve core 53, and a spring 54. The inlet pipe 51 is connected to the discharge bottom plate 46. The top end of the spring 54 is connected to the inlet pipe 51, and the bottom end of the spring 54 is connected to the discharge hopper 52. The top end of the fixed bracket is fixed to the inner wall of the inlet pipe 51. The material blocking valve core 53 is fixed to the bottom end of the fixed bracket and is located in the discharge port of the discharge hopper 52.

[0025] The fixed bracket includes a fixed rod 55, a fixed body 56, and a connecting rod 57. The fixed body 56 is located at the center of the inlet pipe 51. Multiple fixed rods 55 are provided on the top of the fixed body 56, and all of the multiple fixed rods 55 are fixed inside the inlet pipe 51. The connecting rod 57 is rotatably disposed at the bottom of the fixed body 56, and the bottom of the connecting rod 57 is fixed with a material blocking valve core 53. The fixed body 56 is located on the center line of the entire dust suppression hopper 5, and is fixed by the fixed rod at the top. The connecting rod 57 is connected to the top of the material blocking valve core 53, and the material blocking valve core 53 can rotate around the connecting rod.

[0026] The width of the material-blocking valve core 53 is greater than or equal to the width of the discharge port of the hopper 52. The hopper 52 is cone-shaped, and the material-blocking valve core 53 cooperates with the hopper 52 to form an annular discharge port. After the material exits the metering device, it naturally settles in the hopper, releasing the limited air inside. The weight of the material drives the tension spring 54, causing the material to be discharged from the annular discharge port, generating a certain negative pressure. During material conveying, the material is condensed into an airless material column, and the dust is wrapped in the dense column, integrated with the material, with virtually no separation, minimizing the dust generated by the falling material.

[0027] In one technical solution of this utility model, Figure 4 This is a structural diagram illustrating the specific structure of a feeding system according to this utility model, as shown below. Figure 1 As shown, this utility model includes: a feeding pipe 7, a control valve, and a metering dust suppression hopper for grain dispensing as described above. The top of the feeding pipe 7 is connected to the grain depot discharge pipe 1, the control valve is installed on the feeding pipe 7, and the bottom of the feeding pipe 7 is connected to the metering feed pipe 41.

[0028] The control valve includes a start gate valve 3 and a manual slide gate valve 2.

[0029] In this embodiment of the technical solution, a platform 6 is also included. The platform 6 is installed on the side wall of the grain depot, the control valve is located on the platform 6, and the top of the metering device 4 is fixed to the bottom of the platform 6. A person can stand on the platform 6 for convenient control of the manual slide valve 2. Below the fixed platform 6 is the loading position for loading vehicles. The dust suppression hopper 5 is bolted to the metering device 4, and the discharge port of the dust suppression hopper 5 corresponds to the loading position.

[0030] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
