Description

Technical Field

[0001] This utility model relates to the field of concrete additive transportation technology, and in particular to an additive insulation transportation vehicle. Background Technology

[0002] Concrete admixtures are substances added during the concrete mixing process (either simultaneously with the mixing water or added later) to improve the performance of concrete. The dosage is generally no more than 5% of the cement mass. The purpose of using concrete chemical admixtures is primarily to improve certain properties of the concrete mixture or hardened concrete. It does not include grinding aids or setting regulators (such as gypsum) added during cement production to increase cement yield or adjust certain cement properties.

[0003] In the Chinese utility model patent disclosed in document number CN213081890U, a conveying device for building concrete additives is included, comprising a storage box, a screw, and a base. This utility model uses a controller to start an induced draft fan, which enables the powdered concrete additive stored in the storage box via a carrier container to be effectively conveyed to the flexible hose outside the storage box by a guide cover. This allows the powdered concrete additive in the storage box to be evenly and effectively transferred to the concrete in the mixing state, making the mixing of the concrete more uniform and thus effectively making up for the deficiencies in the prior art.

[0004] The aforementioned patent also has drawbacks in its use, such as the lack of a powder stirring structure in the transportation device. When a large amount of powder is stored, it is easy to be squeezed and caking, which affects the quality of the additive and is not conducive to external transportation. Therefore, an additive insulated transportation vehicle is needed to solve this problem. Utility Model Content

[0005] The main purpose of this utility model is to provide an additive-insulated transport vehicle, which solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] An additive heat preservation transport vehicle includes a vehicle body, a first feeding pipe and a second feeding pipe. A hopper is welded and fixed in the inner wall of the vehicle body. The first feeding pipe is sealed and fixed to the bottom of the hopper, and the second feeding pipe is vertically fixed in the vehicle body.

[0008] The first feeding tube includes a first spiral shaft, a first transmission assembly, a transmission shaft, and a second transmission assembly;

[0009] The second feeding tube includes a second spiral shaft and a third transmission assembly.

[0010] Furthermore, a universal wheel is rotatably mounted on one side of the bottom of the vehicle body, and a drive shaft is rotatably connected to the other side of the bottom of the vehicle body via a hanger. The drive shaft has bearings at both ends connected to directional wheels, and a drive bevel gear is also nested and fixed on the drive shaft.

[0011] Furthermore, the second transmission component meshes with the outer side of the drive bevel gear, the second transmission component is welded and fixed to one end of the transmission shaft, the other end of the transmission shaft is nested and connected to the first transmission component, the first transmission component consists of a belt and a pulley, and the first helical shaft is installed in conjunction with the first transmission component.

[0012] Furthermore, the third transmission component meshes with one side of the top of the drive bevel gear, and the output end of the first feeding tube communicates with the inner wall of the second feeding tube.

[0013] Furthermore, a guide elbow is rotatably connected to the top of the second feeding pipe, and a telescopic inner tube is movably installed at the bottom of one end of the guide elbow. The telescopic inner tube is movably installed with the cover at the top of the hopper.

[0014] Furthermore, thermal insulation pads are bonded to the bottom wall of the hopper and the inner wall of the vehicle body. The thermal insulation pads are felt, and a thermal insulation filling layer is provided in the cavity structure at the bottom of the felt. The thermal insulation filling layer is foam.

[0015] Furthermore, a handwheel is also connected to the outside of the second transmission component via a shaft.

[0016] Furthermore, the vehicle body also includes a sealing cover and a handle.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] By setting up a first feeding pipe and a second feeding pipe perpendicular to each other inside the transport vehicle, the first feeding pipe guides the additives carried inside the vehicle from the bottom through the first spiral shaft to the second feeding pipe, and then circulates them upward through the second spiral shaft to the top of the hopper. This achieves the agitation of the powder inside the transport vehicle, which is beneficial for the uniform heat preservation of the inner and outer layers of the powder, and at the same time can avoid prolonged compression during transportation, which would affect the quality and delivery of the powder.

[0026] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0027] like Figures 1-5 As shown, this embodiment provides an additive heat preservation transport vehicle, including a vehicle body 1, a first feeding pipe 2, and a second feeding pipe 3. The vehicle body 1 is characterized by having a hopper 107 welded and fixed to its inner wall, the first feeding pipe 2 sealed and fixed to the bottom of the hopper 107, and the second feeding pipe 3 vertically fixed inside the vehicle body 1. The first feeding pipe 2 includes a first spiral shaft 204, a first transmission assembly 201, a transmission shaft 202, and a second transmission assembly 203. The second feeding pipe 3 includes a second spiral shaft 301 and a third transmission assembly 302.

[0028] like Figure 1 and Figure 5 As shown, a universal wheel 101 is rotatably mounted on one side of the bottom of the vehicle body 1, and a drive shaft 108 is rotatably connected to the other side of the bottom of the vehicle body 1 via a hanger. The drive shaft 108 has bearings at both ends connected to directional wheels 102. A drive bevel gear 109 is also nested and fixed on the drive shaft 108. When the directional wheel 102 rotates, it drives the drive shaft 108 to rotate, which can drive the first spiral shaft 204 and the second spiral shaft 301 inside the vehicle body 1 to rotate and guide the material, so as to achieve the purpose of moving the vehicle and moving the material.

[0029] like Figure 1 , Figure 3 as well as Figure 5 As shown, the second transmission component 203 meshes with the outer side of the drive bevel gear 109. The second transmission component 203 is welded and fixed to one end of the transmission shaft 202. The other end of the transmission shaft 202 is nested and connected to the first transmission component 201. The first transmission component 201 consists of a belt and a pulley. The first spiral shaft 204 is installed in conjunction with the first transmission component 201. The first spiral shaft 204 is in direct contact with the powder and can effectively push the powder out. The transmission shaft 202 is stably supported and rotated at the bottom of the vehicle body 1 by a support frame.

[0030] like Figure 5 As shown, the third transmission component 302 is engaged with one side of the top of the drive bevel gear 109, the output end of the first feeding pipe 2 is connected to the inner wall of the second feeding pipe 3, and the first feeding pipe 2 and the second feeding pipe 3 are sealed and connected.

[0031] like Figure 1 , Figure 3 as well as Figure 4 As shown, the top of the second feeding pipe 3 is rotatably connected to the guide elbow 4, and the bottom of one end is movably installed with a telescopic inner tube 401. The telescopic inner tube 401 is movably installed with the cover on the top of the hopper 107. The guide elbow 4 can rotate flexibly. When it is tumbling and stirring inside, it is located directly above the hopper 107. After the telescopic inner tube 401 at the bottom is squeezed and pushed, it enters the plate at the top of the hopper 107. When discharging material, the telescopic inner tube 401 is pushed into the elbow through the inside of the hopper. Then the guide elbow 4 is rotated to the rear of the vehicle body 1 for discharging. When discharging material, the vehicle body 1 is stationary and the directional wheel 102 does not rotate. At this time, the bottom of the vehicle body 1 needs to be supported so that the directional wheel 102 is suspended in the air. Then the handwheel 5 is turned to drive the first spiral shaft 204 to discharge material.

[0032] like Figure 2 As shown, insulation pads 106 are glued to the bottom wall of the hopper 107 and the inner wall of the vehicle body 1. The insulation pads 106 are felt, and an insulation filling layer 105 is provided in the cavity structure at the bottom of the felt. The insulation filling layer 105 is foam.

[0033] like Figure 1 , Figure 2 as well as Figure 5 As shown, a handwheel 5 is also connected to the outside of the second transmission assembly 203 via a shaft.

[0034] like Figure 1 As shown, the vehicle body 1 also includes a sealing cover 103 and a handle 104.

[0035] The working principle of this device is as follows: When this device is in use, the additive is placed in the hopper 107 and transported by the vehicle body 1. The bottom of the hopper 107 is insulated by the heat insulation pad 106 to form the first layer of heat insulation. At the same time, the heat insulation filling layer 105 set in the cavity at the bottom of the heat insulation pad 106 can reduce the interference of the external temperature of the vehicle body 1 on the hopper 107, so that the additive can be transported stably at both high and low temperatures.

[0036] When the vehicle body 1 moves, the directional wheel 102 drives the drive shaft 108 to rotate, the drive shaft 108 drives the drive bevel gear 109 to rotate, and then drives the second transmission assembly 203 and the third transmission assembly 302 to rotate. The second transmission assembly 203 drives the transmission shaft 202 to rotate, and the transmission shaft 202 drives the first spiral shaft 204 inside the first feeding pipe 2 to rotate through the first transmission assembly 201, which guides the additive at the bottom of the hopper 107 to the second feeding pipe 3. At the same time, the third transmission assembly 302 drives the second spiral shaft 301 to rotate, which transports the incoming additive upward and discharges it from the guide bend 4 into the top of the hopper 107, thereby agitating the additive inside the vehicle body 1.

[0037] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
