Description

Technical Field

[0001] This application relates to the field of grain testing equipment technology, and in particular to a material dispensing hopper. Background Technology

[0002] Grain may be affected by factors such as pests, mold, and moisture changes during storage, necessitating quality testing to ensure the quantity and quality safety of the grain supply. Among related technologies, spectrometers are commonly used to detect multiple indicators in grains, including nutritional components and pesticide residues. In the grain testing process, grain is fed into a hopper with a transparent bottom through a feeding component. The spectrometer scans and tests the grain inside the hopper through this transparent structure. After testing, the hopper is tilted, and the grain is poured into a hopper, which then enters a storage bin.

[0003] However, in actual testing, grain surfaces often have dust or impurities. This dust and impurities can adhere to the bottom of the feed cylinder, obscuring the transparent structure at the bottom of the cylinder and thus affecting the test results of subsequent tests. Utility Model Content

[0004] This application provides a material distribution hopper, which at least solves the problem of impurities accumulating inside the material cylinder and hindering material detection.

[0005] In a first aspect, embodiments of this application provide a material distribution hopper, comprising: a hopper-shaped body, wherein an air vent is provided on the peripheral wall of the hopper-shaped body, the air vent being used to connect a ventilation duct; and a bottom shell, wherein the bottom shell is connected to the bottom of the hopper-shaped body, and a ventilation duct is provided between the bottom shell and the bottom of the hopper-shaped body.

[0006] In some embodiments of this application, the bottom shell extends beyond the bucket-shaped body, and the bottom surface of the bottom shell is an inclined surface that slopes outward from the bucket-shaped body along the direction of gravity.

[0007] In some embodiments of this application, the width of the bottom surface of the bottom shell gradually increases along a first direction, where the first direction is the flow direction of the material on the bottom shell.

[0008] In some embodiments of this application, a guide plate is provided on the bottom shell, one end of the guide plate is disposed inside the ventilation duct, and the other end of the guide plate extends at least along the first direction to the edge of the bottom shell, and the guide plate is used to disperse materials.

[0009] In some embodiments of this application, the deflector plate abuts against the top of the ventilation duct.

[0010] In some embodiments of this application, the guide plate includes a mounting portion and a guide portion connected to the mounting portion, the mounting portion being bent relative to the guide portion, and the mounting portion being connected to the bottom shell.

[0011] In some embodiments of this application, the mounting part and the bottom shell are connected by a connector, which is used to lock and unlock the mounting part and the bottom shell.

[0012] In some embodiments of this application, a plurality of the guide plates are spaced apart in the width direction of the bottom shell.

[0013] In some embodiments of this application, in the two guide vanes, the first dimension of the guide vane closer to the center of the ventilation duct extending into the ventilation duct is greater than the second dimension of the guide vane farther from the center of the ventilation duct extending into the ventilation duct.

[0014] In some embodiments of this application, the projected shape of the air vent is circular.

[0015] The beneficial effects of this application are:

[0016] An air vent is installed on the side wall of the material hopper, connected to a ventilation duct. After material is poured into the hopper from the feed cylinder, air is blown into the feed cylinder through the vent to clean it, maintaining its cleanliness and improving the accuracy of subsequent testing results.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] To facilitate understanding of the embodiments provided in this application, the relevant technologies will first be introduced below in conjunction with application scenarios.

[0028] In the process of testing grains using a spectrometer, the grains are stored in a hopper with a transparent bottom. The spectrometer detects the grains inside the hopper through this transparent structure. After testing, the hopper is tilted, and the grains are poured into a dispensing hopper. The inventors discovered that grain surfaces often contain fine impurities such as dust. These impurities adhere to the bottom of the hopper, affecting the light transmittance of the transparent structure and consequently impacting the results of subsequent grain tests.

[0029] In view of this, this application provides a material dispensing hopper, which is described below in conjunction with... Figures 1-5 The technical solutions disclosed in the various embodiments of this application are described in detail.

[0030] like Figures 1-5 As shown, the material dispensing hopper disclosed in this application includes a hopper-shaped main body 100 and a bottom shell 200. For example... Figure 2 , Figure 5 As shown, the hopper-shaped main body 100 has air vents 110 on its peripheral wall, and the air vents 110 are connected to the fan through the ventilation duct 400. The air blown out by the fan is blown into the material cylinder through the ventilation duct 400 and the air vents 110 to clean the dust and impurities in the material cylinder.

[0031] In the embodiments of this application, the air vent 110 provided on the hopper-shaped main body 100 faces the opening of the inclined material cylinder. Furthermore, since the peripheral wall of the hopper-shaped main body 100 itself has a certain inclination angle, the inclination angle of the side wall where the air vent 110 is located can be adjusted so that the air vent 110 is parallel to the plane where the opening of the material cylinder is located when the grain is poured. That is, the air blown out of the air vent 110 can be completely blown into the material cylinder, improving the utilization rate of the air, thereby improving the cleaning efficiency of the material cylinder, while reducing the loss of wind power resources.

[0032] For example, the shape and size of the air vent 110 correspond to the ventilation duct 400. For instance, the air vent 110 can be rectangular, elliptical, etc. In specific implementations, the projected shape of the air vent 110 can be circular. Specifically, the circular air vent 110 has no sharp edges or corners, and when air flows through it, local eddies and turbulence are not generated, which helps to reduce airflow resistance, energy loss, and wind power loss.

[0033] In some embodiments, a plurality of air vents 110 may be provided on the hopper-shaped body 100, and the plurality of air vents 110 may be located on the same side wall or different side walls of the hopper-shaped body 100. For example, the inclination angles of different side walls of the hopper-shaped body 100 may be different, and the air blown out by the air vents 110 on the side walls with different inclination angles may have different directions. Depending on the usage conditions or application scenarios, the specifications of the material cylinder or the inclination angle of the material cylinder may change. Therefore, the ventilation duct 400 may be connected to the air vent 110 that is adapted to the current angle of the material cylinder, so that the direction of the air blown out by the air vent 110 is consistent with the direction of the material cylinder opening, thereby blowing as much air into the material cylinder as possible, improving the air utilization rate, thereby improving the efficiency of air blowing and cleaning, reducing ventilation time, and reducing the energy consumption of the fan.

[0034] In the embodiments of this application, a bottom shell 200 is connected to the bottom of the hopper-shaped main body 100, and a discharge port 120 is provided between the bottom shell 200 and the bottom of the hopper-shaped main body 100. The discharge port 120 communicates with the bottom of the hopper-shaped main body 100, forming a flow channel for grain. The bottom shell 200 can be connected to the hopper-shaped main body 100 in various ways, such as welding, integral molding, gluing, screw connection, etc.

[0035] Because the peripheral wall of the material distribution hopper is an inclined surface, the air vents 110 on its peripheral wall naturally have an upward tilt angle. Simply connecting a ventilation fan to the air vent 110 allows air to be blown into the material cylinder located above the material distribution hopper for cleaning, eliminating the need for additional cleaning components and further reducing the cleaning cost of the material cylinder. Furthermore, by installing air vents 110 on the material distribution hopper for cleaning the material cylinder, operators only need to turn the ventilation on or off externally to clean the cylinder, making the cleaning process simple and easy, improving the automation level of the material cylinder cleaning process, and enhancing the controllability of the material cylinder cleaning operation.

[0036] In some embodiments, the bottom shell 200 can extend from the discharge port 120 outward from the hopper-shaped body 100, guiding the flow of grain. Further, the bottom surface of the bottom shell 200 is an inclined surface sloping outward from the hopper-shaped body 100 along the direction of gravity. The inclined bottom surface of the bottom shell 200, under the action of gravity, can guide the grain to flow quickly out of the distribution hopper along the flow channel, preventing grain from accumulating in the distribution hopper and affecting the continuity of the grain flow process.

[0037] like Figure 4 As shown, the width of the bottom surface of the bottom shell 200 gradually increases along the first direction. The direction in which the grain flows along the distribution hopper on the bottom shell 200 is the first direction a. Specifically, on the outside of the hopper-shaped main body 100, the height of the side wall of the bottom shell 200 should be higher than the height of the discharge port 120 to prevent grain leakage when flowing out of the discharge port 120. When grain flows into the storage bin 300 along the distribution hopper, it tends to accumulate in the middle, causing grain to overflow from the middle of the storage bin 300 while the rest of the bin remains unfilled, resulting in grain overflow and leakage from the middle. Therefore, increasing the width of the bottom surface of the bottom shell 200 can widen the flow channel for grain, allowing the grain to flow into the storage bin 300 as evenly as possible.

[0038] For example, along the first direction a, the width of the bottom edge of the bottom shell 200 can be adapted to the width of the storage bin 300. In this case, the grain flow channel is consistent with the width of the storage bin 300, allowing the grain to flow evenly from the flow channel to various parts of the storage bin 300, thus ensuring uniform distribution of the grain within the storage bin 300. Furthermore, increasing the width of the bottom surface of the bottom shell 200 expands the grain flow space, thereby accelerating the grain flow speed, increasing the dispensing rate of the dispensing hopper, and ensuring the continuity of the dispensing process.

[0039] In some embodiments, a baffle 210 is also provided on the bottom shell 200. For example... Figure 2 , Figure 3As shown, one end of the guide plate 210 is disposed inside the discharge port 120, and the other end of the guide plate 210 extends at least along the first direction a to the edge of the bottom shell 200. That is, when the grain flows out of the discharge port 120, the guide plate 210 divides different flow channels on the bottom shell 200.

[0040] When the grain flows on the bottom shell 200, it is divided into different channels. The outlets of different channels correspond to different positions in the storage box 300. The grain in each channel falls into the corresponding position, which plays a role in dispersing the grain and preventing the grain from accumulating in some parts of the storage box 300.

[0041] For example, the edge of the deflector 210 can be a straight line, a diagonal line, etc., and the specific shape of the deflector 210 is not limited here.

[0042] In some embodiments, the guide plate 210 abuts against the top of the discharge port 120.

[0043] When material flows out of the discharge port 120, if there is a gap between the guide plate 210 and the top of the discharge port 120, the grain will slide in different flow channels, weakening the diversion effect of the guide plate 210. Simultaneously, if the gap between the guide plate 210 and the discharge port 120 is small, the grain may become stuck in the gap, making it difficult to clean the material hopper and hindering the normal flow of grain. By abutting the top of the guide plate 210 against the discharge port 120, the diversion effect of the guide plate 210 can be further guaranteed, while preventing the grain from getting stuck during flow.

[0044] In some embodiments, such as Figure 2 , Figure 3 As shown, the deflector 210 includes a mounting portion 212 and a flow guide portion 211 connected to the mounting portion 212. Specifically, the flow guide portion 211 and the mounting portion 212 are bent together. For example, the flow guide portion 211 and the mounting portion 212 may be arranged in an L-shape.

[0045] The mounting part 212 is connected to the bottom shell 200. Specifically, the mounting part 212 can be connected to the bottom shell 200 in various ways, such as by gluing or welding.

[0046] By providing a mounting portion 212 that is bent relative to the guide portion 211 and connected to the bottom shell 200, the connection area between the guide plate 210 and the bottom shell 200 can be increased, thereby increasing the stability of the connection between the bottom shell 200 and the guide plate 210.

[0047] In some embodiments, the mounting portion 212 and the bottom shell 200 can also be connected via a connector 220. Specifically, the mounting portion 212 and the bottom shell 200 are connected via a detachable connector 220. That is, when the connector 220 is locked, the mounting portion 212 and the bottom shell 200 are fixedly connected; when the connector 220 is released, the mounting portion 212 can rotate relative to the bottom shell 200 to adjust the flow channel width.

[0048] For example, the connector 220 can be a screw. When the screw is tightened, the mounting part 212 is fixed to the bottom shell 200. When the screw is loosened, the mounting part 212 can rotate relative to the bottom shell 200, thereby causing the width of the flow channel divided by the guide plate 210 to change.

[0049] For example, the connector 220 may also be a pin, key, or other connector that enables a detachable connection between the mounting part 212 and the bottom shell 200, without limitation.

[0050] By setting a detachable connector 220 to connect the bottom shell 200 and the mounting part 212, the mounting part 212 can rotate relative to the bottom shell 200, thereby making the flow channel of grain variable and changing the setting of the flow channel under different diversion requirements, which greatly improves the applicability of the material distribution hopper in a variety of application scenarios.

[0051] In some embodiments, such as Figure 2 , Figure 3 As shown, depending on the width of the bottom shell 200, multiple guide plates 210 can be set on the bottom shell 200 to divide it into multiple flow channels to meet the diversion requirements of grain outflow. Specifically, multiple guide plates 210 are spaced apart in the width direction of the bottom shell 200 to divide it into multiple flow channels and evenly distribute the grain.

[0052] In some embodiments, of the two guide plates 210, the first dimension of the guide plate 210 near the center of the outlet 120 extending into the outlet 120 is greater than the second dimension of the guide plate 210 far from the center of the outlet 120 extending into the outlet 120.

[0053] Since the area of ​​the discharge port 120 is limited, if too many guide plates 210 are installed, it may significantly encroach on the opening of the discharge port 120, thereby narrowing the channel for grain flow and slowing down or even hindering grain flow. Therefore, when multiple guide plates 210 are installed, the size misalignment of the guide plates 210 into the discharge port 120 can prevent the discharge port 120 from being excessively blocked.

[0054] Furthermore, when grain is poured into the distribution hopper, the largest amount of grain is located at the center of the hopper. Under the influence of gravity, most of the grain will flow into the central channel, while a small portion will be dispersed to the side channels. Therefore, the guide plate 210 near the center can be appropriately extended deeper into the discharge port 120. Figure 2 , 3 As shown, one end of the guide plate 210, which extends into the discharge port 120, is located at the center of the hopper-shaped body 100. Due to the isolating effect of the guide plate 210, the grain poured out of the feed cylinder is divided into different channels within the hopper-shaped body 100. As the depth of the guide plates 210 into the hopper-shaped body 100 varies sequentially, the grain is divided layer by layer into different channels to achieve uniform dispersion.

[0055] For example, the spacing between the guide plates 210 located at the center of the distribution hopper can be reduced to decrease the amount of grain flowing into the middle channel, thereby balancing the amount of grain in different channels and further dispersing the grain.

[0056] By flexibly setting the position of the guide plate 210 on the bottom shell 200, the flow channel setting method can be effectively adjusted according to the flow characteristics and particle size of different grains, so that the grain can be evenly divided into different flow channels and then evenly scattered into the storage box 300, avoiding excessive accumulation of grain in the middle of the storage box 300. Furthermore, it can also reduce the leakage problem caused by uneven grain flow.

[0057] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art.
