Description

Technical Field

[0001] This utility model belongs to the field of yam powder processing technology, specifically relating to an improved receiving hopper below the discharge port of an extruder. Background Technology

[0002] During the puffing process of yam powder, when starting the machine, to facilitate the smooth extrusion of yam powder from the puffing machine, about a bottle of purified water (also called priming water) is usually added along with the powder at the feed inlet. The addition of priming water makes the yam powder too moist and unable to form properly, resulting in unstable puffing degree and preventing it from entering the cooling air bed and crusher normally. Therefore, when adding water to assist priming, the puffed balls and water droplets with high humidity that are extruded during puffing should be caught with a plate first, otherwise they will fall into the receiving hopper below the puffing machine outlet. Using a plate to catch the material requires a rectangular opening above the receiving hopper for horizontal placement and removal of the plate. Placing and removing the plate is inconvenient and it is easy for material (puffed balls with high humidity) to leak into the receiving hopper. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, this utility model provides an improved receiving hopper below the discharge port of an extruder that is simple in structure, easy to operate, and does not leak material.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an improved receiving hopper below the discharge port of the extruder, including a hopper body with an open top, a wet material discharge port with internal and external permeability on the right side plate of the hopper body, the front and rear sides of the wet material discharge port respectively connecting to the front and rear side plates of the hopper body, a front hinge is provided on the right side of the front side plate of the hopper body, and a rear hinge corresponding to the front hinge is provided on the right side of the rear side plate of the hopper body, a flap that can close the wet material discharge port is provided between the front and rear hinges, the front side of the flap contacts the inner wall of the front side plate of the hopper body, the rear side of the flap contacts the inner wall of the rear side plate of the hopper body, the upper part of the flap is located inside the hopper body and fits against the inner wall of the right side plate, and the lower part of the flap is located outside the hopper body and fits against the outer wall of the right side plate.

[0005] The top of the hopper body is horizontally covered with a cover plate, and a material discharge hole is provided in the middle of the cover plate. A guide cylinder is provided in the material discharge hole. The outer diameter of the guide cylinder is equal to the diameter of the material discharge hole. The lower end of the guide cylinder is 3-10cm away from the cover plate. A support limiting ring is provided on the lower outer circle of the guide cylinder and pressed against the upper surface of the cover plate.

[0006] The front and rear hinges have the same structure, both including a fixed seat connected to the hopper body by screws. A fixed sleeve with front and rear openings is fixedly provided on the right side of the fixed seat, and a rotating shaft is rotatably provided inside the fixed sleeve. The rear end of the rotating shaft of the front hinge is fixedly connected to the front side of the flap, and the front end of the rotating shaft of the rear hinge is fixedly connected to the rear side of the flap.

[0007] The angle between the portion of the flap above the pivot and the portion of the flap below the pivot is an obtuse angle.

[0008] The inner wall of the right side plate of the hopper body is provided with an upper shallow groove above the wet material discharge outlet, which fits with the upper side of the flap plate, and the inner wall of the right side plate of the hopper body is provided with a lower shallow groove below the wet material discharge outlet, which fits with the lower side of the flap plate.

[0009] Compared with the prior art, the working principle and beneficial effects of this utility model using the above technical solution are as follows: 1) When the extruder is first started, a lot of water is added to the yam powder, and the extruded balls have high humidity. At this time, it is necessary to prevent these high humidity extruded balls from falling into the receiving hopper. Push the upper part of the flap to the left, and rotate the upper side of the flap to contact the inner wall of the left side plate of the hopper body. At this time, the wet material discharge port is opened, and the flap is set with the left side higher than the right side. The extruded balls falling from the extruder outlet fall into the flap inside the hopper body through the guide cylinder, and then roll along the left side higher than the right side of the flap, and are discharged from the hopper body through the wet material discharge port. After the high humidity extruded balls are completely discharged, press down the bottom of the flap. The flap rotates around the pivot until the upper side of the flap enters the upper shallow groove and the lower side of the flap enters the lower shallow groove. The flap blocks the wet material discharge port, and the extruded balls falling from the extruder outlet fall directly to the bottom of the hopper body, and the extruder performs normal extrusion operation.

[0010] 2) The left side plate of the hopper body is inclined with the left side higher than the right side, and the right side plate of the hopper body is inclined with the left side lower than the right side. When the wet material discharge outlet is opened, the upper side of the flap plate can press against the inner wall of the left side plate of the hopper body, making the flap plate a guide plate with the left side higher than the right side. When the wet material discharge outlet is closed, the flap plate is inclined with the left side lower than the right side, which has better stability. At the same time, when it is impacted by the falling puffed balls, it fits more tightly with the right side plate, thus ensuring the stability of the flap plate without the need for a positioning structure.

[0011] 3) The guide cylinder guides the puffed balls from the puffer outlet to the receiving hopper. The limiting support ring fixed on the lower outer circle of the guide cylinder supports the guide cylinder when placed on the cover plate. When it is necessary to clean the inside of the receiving hopper, the guide cylinder can be lifted upwards from the cover plate, and the inside of the receiving hopper can be cleaned through the discharge hole on the cover plate.

[0012] 4) The front and rear hinges facilitate installation and disassembly. In particular, the friction between the pivot and the fixed sleeve ensures that the flap remains stable in both positions when no external force is applied.

[0013] 5) The upper and lower shallow troughs are designed so that when the wet material outlet is closed, the upper and lower parts of the flap are respectively inserted into the upper and lower shallow troughs, which further ensures the stability of the flap.

[0014] 6) The front and rear side plates of the hopper body are both vertically arranged, and the flap is rectangular. When the flap rotates, it maintains a small gap with the front and rear side plates to avoid material leakage and ensure the smooth discharge of the puffed balls.

[0015] In summary, this utility model has a scientific principle and a simple structure. When the extruder is started, there is no need to place a plate on top of the hopper body. Simply rotate the flip plate to open the wet material discharge port to discharge the extruded balls with high humidity. During normal extrusion operation, simply rotate the mold plate to block the wet material discharge port. The operation is very convenient and there will be no leakage. Attached Figure Description

[0022] like Figures 1-5 As shown, the improved receiving hopper below the discharge port of the extruder of this utility model includes a hopper body 1 with an open top. The right side plate 2 of the hopper body 1 has a wet material discharge port 3 that is transparent to both the inside and outside. The front and rear sides of the wet material discharge port 3 are respectively connected to the front side plate 4 and the rear side plate 5 of the hopper body 1. A front hinge 6 is provided on the right side of the front side plate 4 of the hopper body 1, and a rear hinge 7 corresponding to the front hinge 6 is provided on the right side of the rear side plate 5 of the hopper body 1. A flap 8 that can close the wet material discharge port 3 is provided between the front hinge 6 and the rear hinge 7. The front side of the flap 8 contacts the inner wall of the front side plate 4 of the hopper body 1, and the rear side of the flap 8 contacts the inner wall of the rear side plate 5 of the hopper body 1. The upper part of the flap 8 is located inside the hopper body 1 and is attached to the inner wall of the right side plate 2, and the lower part of the flap 8 is located outside the hopper body 1 and is attached to the outer wall of the right side plate 2.

[0023] The top of the hopper body 1 is horizontally provided with a cover plate 9. The middle of the cover plate 9 is provided with a discharge hole. A guide cylinder 10 is provided in the discharge hole. The outer diameter of the guide cylinder 10 is equal to the diameter of the discharge hole. The lower end of the guide cylinder 10 is 3-10cm away from the cover plate 9. The lower outer circle of the guide cylinder 10 is provided with a support limiting ring 11 that is pressed against the upper surface of the cover plate 9.

[0024] The front hinge 6 and the rear hinge 7 have the same structure, both including a fixed seat 12 connected to the hopper body 1 by screws. A fixed sleeve 13 with front and rear opening is fixedly provided on the right side of the fixed seat 12. A rotating shaft 14 is rotatably provided inside the fixed sleeve 13. The rear end of the rotating shaft 14 of the front hinge 6 is fixedly connected to the front side of the flip plate 8, and the front end of the rotating shaft 14 of the rear hinge 7 is fixedly connected to the rear side of the flip plate 8.

[0025] The angle between the portion of the flap 8 above the rotating shaft 14 and the portion of the flap 8 below the rotating shaft 14 is an obtuse angle.

[0026] The inner wall of the right side plate 2 of the hopper body 1 is provided with an upper shallow groove 15 above the wet material discharge outlet 3, which fits with the upper side of the flap 8. The inner wall of the right side plate 2 of the hopper body 1 is provided with a lower shallow groove 16 below the wet material discharge outlet 3, which fits with the lower side of the flap 8.

[0027] The working process of this utility model is as follows: When the extruder is first started, a large amount of water is added to the yam powder, resulting in high humidity in the extruded balls. To prevent these high-humidity balls from falling into the receiving hopper, the upper part of the flap 8 is pushed to the left, causing the upper side of the flap 8 to contact the inner wall of the left side plate of the hopper body 1. At this time, the wet material discharge port 3 opens, and the flap 8 is tilted with the left side higher than the right. The extruded balls falling from the extruder outlet pass through the guide cylinder 10 and fall into the hopper body 1. The material is fed onto the flap 8, and then rolled along the flap 8 which is higher on the left and lower on the right. The material is discharged from the hopper body 1 through the wet material discharge outlet 3 until the puffed balls with higher humidity are completely discharged. Then, the bottom part of the flap 8 is pressed down, and the flap 8 rotates around the pivot 14 until the upper side of the flap 8 enters the upper shallow trough 15 and the lower side of the flap 8 enters the lower shallow trough 16. The flap 8 blocks the wet material discharge outlet 3, and the puffed balls falling from the puffer outlet fall directly to the bottom of the hopper body 1, and the puffer performs normal puffing operation.
