Description

Technical Field

[0001] The utility model relates to the technical field of auger conveyors, in particular to a material sealing baffle for a batching auger conveyor. Background Art

[0002] Auger conveyor is an industrial conveying equipment used to transport large amounts of granular solids (such as powders, grains, pellets), semi-solids, liquids and even non-flowing materials from one point to another. It is mainly composed of a batching auger shaft installed in a trough. Due to the hysteresis of the auger stopping, when the electrical signal is transmitted to the auger motor, some materials slide from the batching auger to the batching scale under the action of inertia, resulting in poor control of feed batching accuracy. In order to control the batching accuracy, the only option is to adjust the material column, which prolongs the inching time and reduces the batching speed, which cannot meet the full-load production of feed batching operations.

[0003] After searching, the Chinese patent application number CN202322591864.2 discloses an auger conveyor for feed production, including a base, a fixed seat and a rotating seat are respectively installed on both sides of the plane of the base, and a rotating frame is installed on the fixed seat. However, since the above technical solution does not have a corresponding mechanism that can timely seal the material inside the auger conveyor, there is still a problem that after the auger conveyor stops, the internal material will slide from the auger mouth under the action of inertia, resulting in inaccurate feed ingredients. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a material sealing baffle for a batching auger conveyor.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A material sealing baffle for a batching auger conveyor comprises a fixing plate welded and fixed to the inner wall of the auger conveyor housing, a spring hinge being fixed to the outer wall of the fixing plate by screws, a baffle body being fixed to the outer wall of the spring hinge by screws, and a reserved groove being provided on the outer wall of the baffle body.

[0007] As a further solution of the present invention: an auger mouth is opened on the inner wall of the outer shell of the auger conveyor, and an auger shaft is rotatably connected to the inner wall of the auger mouth.

[0008] As a further solution of the present invention: an auger piece is fixed to the outer wall of the auger shaft, and a discharge port is opened on the outer wall of the bottom of the auger conveyor shell.

[0009] As a further solution of the present invention: a group of buffer blocks are fixed to the outer wall of one side of the baffle body.

[0010] As a further solution of the present invention: an elastic sleeve is fixed to the inner wall of the reserved groove.

[0011] As a further solution of the present invention: a support plate is fixed to the bottom inner wall of the auger conveyor shell, a guide plate is fixed to the top outer wall of the support plate, and the auger shaft is slidably connected to the top outer wall of the guide plate.

[0012] As a further solution of the present invention: a conical block is fixed to the outer wall of one side of the support plate.

[0013] The beneficial effects of the utility model are:

[0014] 1. During batching, the auger shaft rotates, driving the material to push the baffle body open automatically. When batching stops, an electrical signal is transmitted to the feeding motor, causing the feeding motor to stop. The baffle body closes under the elastic force of the spring hinge, blocking the auger mouth and preventing the material from falling through the auger mouth and discharge port into the batching scale. This improves the batching scale's feeding accuracy. By adding a sealing baffle to the batching auger, the requirements for precise batching can be achieved. By improving batching accuracy and production efficiency, reducing production costs and energy consumption, and optimizing production processes and management efficiency, overall production efficiency and competitiveness can be improved.

[0015] 2. The buffer block can provide a buffer between the baffle body and the auger conveyor casing on one side to prevent the baffle body from colliding hard with the outer wall of the auger conveyor casing when it is closed under the elastic force provided by the spring hinge. At the same time, the elastic sleeve can protect the reserved groove and the auger shaft to prevent the reserved groove from rubbing against the outer wall of the auger shaft when it rotates up and down with the baffle body.

[0016] 3. The support plate and the guide plate can support the auger shaft while sealing the gap between the reserved slot and the auger conveyor casing, thereby improving the sealing effect of the baffle body on the auger opening on one side of the auger conveyor casing. At the same time, when the baffle body is opened under the impact of the material inside the auger conveyor casing, the conical block on one side of the support plate can reduce the impact force of the material on the support plate, thereby preventing the support plate from causing a large obstruction to the discharged material.

[0027] Example 1

[0028] A sealing baffle for a batching auger conveyor, such as Figure 1-5 As shown, it includes a fixed plate 1 welded and fixed to the inner wall of the auger conveyor housing 2, the outer wall of the fixed plate 1 is fixed with a spring hinge 6 by screws, the outer wall of the spring hinge 6 is fixed with a baffle body 5 by screws, and the outer wall of the baffle body 5 is provided with a reserved groove 8;

[0029] An auger mouth 7 is opened on the inner wall of the auger conveyor housing 2, and the inner wall of the auger mouth 7 is rotatably connected to the auger shaft 3; an auger piece 13 is fixed on the outer wall of the auger shaft 3, and a discharge port 4 is opened on the outer wall of the bottom of the auger conveyor housing 2.

[0030] In this embodiment, a 270mm long and 40mm wide flat iron plate serves as the fixed plate 1. Two 80mm medium-sized spring hinges 6 connect the fixed plate 1 to the baffle body 5, ensuring sufficient elasticity. During batching, the auger shaft 3 rotates, driving the material to push the baffle body 5 open automatically. When batching stops, an electrical signal is transmitted to the feed motor, stopping the feed motor. The baffle body 5 closes under the elastic force of the spring hinges 6, blocking the auger opening 7. This prevents material from falling through the auger opening 7 and the discharge port 4 into the batching scale, thereby improving the batching scale's discharge accuracy.

[0031] Before using this sealing baffle, the batching accuracy of the auger conveyor was not very high and difficult to control. After using this sealing baffle, the batching accuracy has been greatly improved: the batching error of more than 2 kg has dropped from 9.18% to 7.23%;

[0032] Before using this sealing baffle, batching efficiency was 5 minutes per tray. After using it, batching speed increased from 5 minutes per tray to 3.5 minutes per tray. Based on a 100-tray shift, this saves 150 minutes per shift (1.5 minutes x 100). Based on a monthly production volume of 2,000 tons, this saves 25 hours. The total power consumption of the idling auxiliary equipment is calculated to be 503.85 kW, which translates to approximately 500 kWh per hour. At 0.5 yuan per kWh, this reduces the monthly losses from idling auxiliary equipment by 25 x 500 x 0.5 = 6,250 yuan.

[0033] By adding a sealing baffle to the batching auger, the requirement for precise batching can be achieved. This is reflected in improving batching accuracy and production efficiency, reducing production costs and energy consumption, and optimizing production processes and management efficiency, thereby improving overall production efficiency and competitiveness.

[0034] Working Principle: The fixed plate 1 and the baffle body 5 are connected by a medium-sized spring hinge 6, ensuring sufficient elasticity in the baffle body 5. During batching, the auger shaft 3 rotates, driving the material, pushing the baffle body 5 open automatically. When batching stops, an electrical signal is transmitted to the feeding motor, causing the feeding motor to stop. The baffle body 5 closes under the elastic force of the spring hinge 6, blocking the auger mouth 7 and preventing the material from falling through the auger mouth 7 and the discharge port 4 into the batching scale.

[0035] Example 2

[0036] A sealing baffle for a batching auger conveyor, such as Figure 4-5As shown, this embodiment makes the following improvements on the basis of embodiment 1: a group of buffer blocks 9 are fixed to the outer wall of one side of the baffle body 5; an elastic sleeve 10 is fixed to the inner wall of the reserved groove 8; a support plate 12 is fixed to the inner wall of the bottom of the auger conveyor housing 2, a guide plate 11 is fixed to the outer wall of the top of the support plate 12, and the auger shaft 3 is slidably connected to the top outer wall of the guide plate 11; a tapered block 14 is fixed to the outer wall of one side of the support plate 12;

[0037] The buffer block 9 can buffer the space between the baffle body 5 and the auger conveyor casing 2 on one side, to avoid a hard collision between the baffle body 5 and the outer wall of the auger conveyor casing 2 when the baffle body 5 is closed under the elastic force provided by the spring hinge 6. At the same time, the elastic sleeve 10 can protect the reserved groove 8 and the auger shaft 3, to avoid friction between the reserved groove 8 and the outer wall of the auger shaft 3 when the baffle body 5 rotates up and down. The support plate 12 and the guide plate 11 can support the auger shaft 3 while blocking the gap between the reserved groove 8 and the auger conveyor casing 2, thereby improving the blocking effect of the baffle body 5 on the auger mouth 7 on one side of the auger conveyor casing 2. At the same time, when the baffle body 5 is opened under the impact of the material inside the auger conveyor casing 2, the conical block 14 located on one side of the support plate 12 can reduce the impact force of the material on the support plate 12, to avoid the support plate 12 causing a large obstruction to the discharged material.

[0038] Working principle: The buffer block 9 can buffer the space between the baffle body 5 and the auger conveyor casing 2 on one side to prevent the baffle body 5 from colliding hard with the outer wall of the auger conveyor casing 2 when the baffle body 5 is closed under the elastic force provided by the spring hinge 6. At the same time, the elastic sleeve 10 can protect the reserved groove 8 and the auger shaft 3 to prevent the reserved groove 8 from rubbing with the outer wall of the auger shaft 3 when the baffle body 5 rotates up and down. The support plate 12 and the guide plate 11 can support the auger shaft 3 while sealing the gap between the reserved groove 8 and the auger conveyor casing 2.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
