Abstract
Description
Technical Field
[0001] This utility model belongs to the field of powder storage and transportation technology, specifically relating to an anti-compacting vehicle-mounted silo. Background Technology
[0002] During cement transportation, truck-mounted cement silos are mainly used for loading, transporting, and conveying powdery materials such as cement. During transport, due to road bumps, the vehicles are constantly subjected to vibration, which is directly transmitted to the truck-mounted cement silos. Under continuous vibration, cement particles are prone to compaction or densification, leading to decreased cement fluidity and, in severe cases, the formation of caking lumps. These compacted or caking cement particles may block the discharge port.
[0003] In addition, if cement stored in a cement silo is not used for a long time, changes in the external environment, such as increased humidity, will cause the cement to absorb moisture from the air, which will also cause the cement to clump together.
[0004] Blockage at the discharge port directly affects the cement unloading and conveying process, preventing the cement from being unloaded smoothly and thus impacting project progress. To address this issue, existing technologies typically install vibratory motors or pneumatic arch-breaking devices on the cement silo to assist material flow. Vibratory motors loosen accumulated cement particles through vibration, while pneumatic arch-breaking devices utilize airflow to disrupt the arched material structure.
[0005] However, these existing technologies cannot completely solve the problems of cement particle compaction and caking. The effects of vibratory motors and pneumatic arch-breaking devices are generally limited and may not be effective in preventing material compaction in all cases. Especially during long-term transportation or storage, cement may have already undergone significant compaction or caking, making it impossible for existing auxiliary discharge measures to completely clear blockages. Utility Model Content
[0006] The technical problem to be solved by this utility model is: how to design a vehicle-mounted silo that prevents compaction and breaks up severe compaction or caking.
[0007] The specific technical solution of this utility model is as follows:
[0008] An anti-compaction vehicle-mounted hopper includes a connected hopper and a discharge hopper. The discharge hopper is cone-shaped and located below the hopper. A loosening rotating component is rotatably installed inside the discharge hopper to loosen the material.
[0009] The loosening rotating component includes a loosening shaft and a fixed protrusion in the radial direction of the loosening shaft.
[0010] The protrusion can be a protruding post, so that the protruding post and the loosening shaft together form a mace shape.
[0011] The loosening shaft is set along the axial direction of the discharge hopper.
[0012] The protrusion can be an external helical blade, so that the protrusion and the loosening shaft together form an auger shape.
[0013] Loosen one end of the rotating shaft, which extends to the outside of the discharge hopper, and fixes the driven wheel.
[0014] A horizontal auger is fixed at the lower end of the discharge hopper. When the shaft is loosened and rotated, the protrusion can transport the material backward.
[0015] If there are two discharge hoppers side by side, the two side walls closest to the edge are the outer side walls, and the two side walls closest to the middle are the inner side walls.
[0016] Multiple loosening discs are fixed in the radial direction of the loosening shaft, and several loosening needles are hinged to the loosening discs.
[0017] Compared with the prior art, the technical effect of this utility model is that it is equipped with a loosening shaft, which can be used to break up compaction or caking, making unloading and conveying smoother. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the end face of this utility model.
[0020] Figure 3 This is a cross-sectional schematic diagram of the present invention.
[0021] Figure 4 This is a schematic diagram of the force analysis of materials during a turn.
[0022] Figure 5 This is a schematic diagram of the protruding part. Detailed Implementation
[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0024] In this instruction manual, the discharge direction of the horizontal auger 21 is used ( Figure 3 The left side is front, and the opposite direction is back.
[0025] like Figure 1-3 An anti-compaction vehicle-mounted hopper includes a hopper 10 and a discharge hopper 20 connected together. The discharge hopper 20 is conical and located below the hopper 10. A loosening rotating component 30 is rotatably provided inside the discharge hopper 20, which is used to loosen the material.
[0026] like Figure 3The loosening rotating component 30 includes a loosening rotating shaft 32 and a fixed protrusion 33 in the radial direction of the loosening rotating shaft 32.
[0027] The protrusion 33 can be a protruding post, so that the protruding post and the loosening shaft 32 together form a mace shape.
[0028] like Figure 5 Multiple loosening discs 35 are fixed in the radial direction of the loosening shaft 32, and several loosening needles 36 are hinged on the loosening discs 35.
[0029] When there is a lot of material in the discharge hopper 20, if the diameter of the loosening disc 35 is large, there will be ineffective friction, affecting rotation; when there is a little material in the discharge hopper 20, if the diameter of the loosening disc 35 is small, the loosening disc 35 cannot rub against the material, affecting loosening.
[0030] Now, after "several loosening needles 36 are hinged to the loosening disc 35", when the diameter of the loosening disc 35 is small, the loosening needles 36 are obstructed, forced to retract, and located on one side of the loosening disc 35; when the diameter of the loosening disc 35 is large, the loosening needles 36 are subjected to centrifugal force and located on the outside (that is... Figure 5 (Position), enabling adaptive changes in the diameter of the protrusion 33.
[0031] like Figure 3 The protrusion 33 can be an external helical blade, so that the protrusion and the loosening shaft 32 together form an auger shape.
[0032] like Figure 1 One end of the loosening shaft 32 extends to the outside of the discharge hopper 20 and fixes the passive wheel 31. The passive wheel 31 can be connected to the drive component, so that the drive component provides power to the loosening shaft 32.
[0033] like Figure 3 To ensure uniformity, the loosened rotating shaft 32 is positioned along the axial direction of the discharge hopper 20.
[0034] like Figure 3 During unloading and conveying, as shown by arrows A91 and B92, the material enters the horizontal auger 21 along the outlet and then exits from the horizontal auger 21. During the discharge process, the inventors noted:
[0035] After the material behind the discharge bin 20 enters the rear section 211 of the horizontal auger 21, it occupies the space of the horizontal auger 21. When the material moves to the front section 212 of the horizontal auger 21, the chance of the material in front of the discharge bin 20 entering the front section 212 of the horizontal auger 21 becomes weaker. Therefore, the material discharge speed in front of the discharge bin 20 is lower than that behind it. In the later stage of discharge (that is, after the material behind the discharge bin 20 has been discharged), only the material in front of the discharge bin 20 enters the front section 212 of the horizontal auger 21, resulting in low discharge efficiency.
[0036] Therefore, the following step should be taken:
[0037] The protrusion 33 is an external spiral blade. The lower end of the discharge bin 20 is fixed with a horizontal auger 21. When the rotating shaft 32 is loosened, the protrusion 33 can transport the material backward, as shown by arrow C93.
[0038] In this way, the material moves backward as a whole, allowing for a longer period of simultaneous discharge from both the front and rear of the discharge hopper, resulting in higher discharge efficiency.
[0039] like Figure 4 If there are two discharge hoppers 20 side by side, of the four side walls of the discharge hopper 20, the two closest to the edge are the outer side walls 201, and the two closest to the middle are the inner side walls 202.
[0040] During transportation, the inventor noticed:
[0041] Due to vehicle lane changes, turns, and other operations, under the action of centrifugal force (also known as inertial force), the material 81 in the middle of the hopper 10 will move outward. Taking the vehicle turning left as an example, see arrow D82. The material 81 will move to the right. Because it is blocked by the side wall of the hopper 10, see arrow E83. The material 81 will turn downward and press against the outer wall 201 on the right side, making the material at the outer wall 201 (see attached reference numeral 84) more compact. Therefore, the outer wall 201 has a greater chance of "severe compaction or hardening" than the inner wall 202.
[0042] Therefore, the following step should be taken:
[0043] Loosen the side of the rotating shaft 32 near the outer wall 201, so that the material on the outer wall 201 can be loosened more easily.
[0044] Its working principle is as follows:
[0045] During the discharge process, a drive unit can be used to provide power to the loosening shaft 32, causing the loosening shaft 32 to rotate, and its protrusion 33 and the material it carries will be loosened.
[0046] Features of this application:
[0047] S1. Effectively prevents cement compaction: The anti-compression device breaks up the cement during rotation, preventing it from hardening and clogging, and ensuring smooth discharge of cement.
[0048] S2. Simple structure and easy maintenance: The screw device can be disassembled and replaced, reducing maintenance costs.
[0049] For other details, please refer to the existing technology.
[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
