Description

Technical Field

[0001] The invention relates to the field of grain processing, in particular to a feeding hopper used for evenly spreading grain waterfalls. Background Art

[0002] Before grain enters the granary, it is usually screened by a screening machine to remove impurities, such as inorganic impurities such as gravel, sand, metal substances, and organic impurities such as grass leaves and wood chips, plant roots, stems and leaves, plastic products, etc., so as not to affect the use and storage value of the grain.

[0003] During the use of the existing screening machine, a feed hopper is generally set above one end of the screening machine to allow grain to fall into the feed hopper through a belt conveyor. However, the existing feed hoppers are fixed, and their discharge speed and height are fixed. Straws and weeds in the impurities are easy to accumulate and block the feed hopper. When the grain reaches the discharge port of the feed hopper, it is easy to get blocked and arched, which requires manual cleaning by the staff, which is dangerous. Therefore, we propose a grain feed hopper to make the grain waterfall spread out at different angles and evenly distributed when the grain falls from the conveyor belt to the feed hopper, so as to reduce the difficulty of controlling the discharge and avoid blockage of the discharge port. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a feeding hopper for evenly dispersing grain waterfalls.

[0007] As a preferred technical solution of the present invention, the support bottom plate is in an inverted U shape, and the lower surface of the support bottom plate is welded to the upper surface of the second side wall.

[0011] As a preferred technical solution of the present invention, the hopper body is fixedly mounted on the vibrating screen, and the hopper body and the vibrating screen vibrate periodically at the same frequency.

[0012] As a preferred technical solution of the present invention, a grain conveyor belt is arranged above the hopper body, and the end of the grain conveyor belt is located just above the dividing plate, so as to cascade the grain onto the dividing plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] In the drawings, the same reference numerals all refer to the same components.

[0017] like Figure 1-3 As shown, the present invention provides a feed hopper for uniformly dispersing a grain waterfall, comprising a hopper body 1, a first side wall 2 is formed on one side of the hopper body 1, a second side wall 3 is arranged opposite to the first side wall 2, two symmetrically arranged connecting side walls 4 are arranged between the first side wall 2 and the second side wall 3, the first side wall 2 and the second side wall 3 form a V shape, a dividing plate 5 is arranged above the second side wall 3, a supporting bottom plate 6 is connected below the dividing plate 5, and a cover plate 7 is hinged on the second side wall 3. The present invention realizes effective diversion of the grain waterfall after falling through the design of the dividing plate 5, thereby avoiding the defect that the impurities block the discharge port due to the concentrated waterfall flow, and at the same time improves the processing efficiency of the feed hopper.

[0018] The use of the present invention is as follows: 1. The grain waterfall is transported to a high point through a grain conveyor belt (not shown), and then, under the action of gravity, forms a grain waterfall and falls onto the dividing plate 5 located below the grain conveyor belt; 2. When the grain waterfall falls to the lowest point, it is blocked by the dividing plate 5 and then dispersed evenly in all directions. After some grains splash onto the first side wall 2, they are blocked by the first side wall 2 and then slide down along the first side wall 2 to the bottom discharge port. Some grains are diverted to the left and right sides of the dividing plate 5 by the inclined surface of the dividing plate 5, and then naturally fall along the second side wall 3 to the bottom discharge port. 3. In this way, a uniform grain flow is formed at the discharge port at the bottom of the hopper body 1, and then falls onto the screen of the vibrating screen located below the grain hopper.

[0019] Furthermore, the dividing plate 5 is an inverted V-shape, the middle part of the V-shape is welded to the supporting bottom plate 6 through the vertical connecting plate 8, and the bottom of the V-shape is welded to the upper surface of the supporting bottom plate 6, which is used to support the dividing plate 5 to prevent deformation caused by the grain waterfall falling and impacting the dividing plate 5. The dividing plate 5 is used to make the grain waterfall evenly disperse at a certain angle during the falling process. When the sand, grass leaves, wood chips, etc. in the grain waterfall fall onto the dividing plate 5, they are blocked by the inclined surface and evenly spread, avoiding the problem of impurities concentrating and clogging the discharge port. In addition, by designing the inclination angle of the V-shape, the rate of material falling can be increased, thereby improving the feeding efficiency of the feed hopper, the rate of grain screening, and ultimately the output of screened grain.

[0020] According to existing research results, for granular food materials, the calculation formula corresponding to the processing rate of the funnel is:

[0021] In the above calculation formula: M is the processing rate of the grain hopper; V is the conveying speed of the conveyor belt; T is the processing time; ρ is the density of grain particles; S is the area of ​​the discharge port of the feed hopper funnel; a is the length of the discharge port; b is the width of the discharge port; First mapping table: conveying speed of different conveyor belts

[0022] According to relevant literature, the grain density (taking rice as an example) ρ in my country is 1170-1220 kg / m³. In this embodiment, the conveying speed is 1.45 m / s; the time T is set to 3600 s; the rice density ρ=1200 kg / m³; the discharge port length a is set to 0.4 m; the width b is set to 0.1 m; substituting the above values ​​into calculation formulas (1) and (2), After calculation, the current grain hopper processing efficiency per hour can be obtained: M=250t / H, which means 250t of grain can be processed per hour; Furthermore, the support bottom plate 6 is in an inverted U shape, and the lower surface of the support bottom plate 6 is welded to the upper surface of the second side wall 3. The inverted U-shaped design can disperse the impact force borne by the middle part of the dividing plate 5 to both sides.

[0023] Furthermore, the cover plate 7 is concave in shape, a hinge shaft is provided on one side of the cover plate 7, a hinge hole is provided on the side of the second side wall 3, the cover plate 7 is hingedly connected to the second side wall 3, the cover plate 7 can rotate along the second side wall 3, and when the feed hopper is not in use, the cover plate 7 can be closed to protect the internal structure of the feed hopper from contamination or corrosion.

[0024] Furthermore, a discharge port is provided at the bottom of the hopper body 1, and the discharge port is rectangular in shape. The rectangular discharge port design is conducive to the smooth discharge of grain and prevents local blockage.

[0025] Furthermore, a filter screen for filtering impurities is provided below the hopper body 1, and the filter screen is arranged parallel to the lower surface of the hopper body 1. Preferably, a multi-layer filter screen is provided below the hopper body 1 to effectively filter impurities in the grain.

[0026] Furthermore, the hopper body 1 is fixedly mounted on the vibrating screen, and the hopper body 1 and the vibrating screen vibrate periodically at the same frequency. When the grain enters the hopper body 1, the grain can slide onto the filter more smoothly under the continuous periodic vibration of the hopper body 1, thereby improving the screening efficiency and avoiding local blockage.

[0027] Furthermore, a grain conveyor belt is provided above the hopper body 1, and the end of the grain conveyor belt is located just above the dividing plate 5, ensuring that the grain waterfall can fall into the middle of the dividing plate 5 after falling, thereby ensuring the efficiency of the falling material.

[0028] The invention discloses a feeding hopper for uniformly dispersing a grain waterfall. The V-shaped material dividing plate is designed to achieve uniform dispersing of the grain waterfall and the technical effect that grain is not easily blocked.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
