Description

Technical Field

[0001] This utility model relates to the field of transportation technology, specifically to a spiral-driven, horizontally moving garbage transfer vehicle. Background Technology

[0002] In the truck transportation industry, for some trucks with fixed cargo compartments, the existing unloading method typically involves using horizontal hydraulic cylinders to push a crossbar, which then pushes the cargo out of the compartment. However, this method has some significant drawbacks. During use, the hydraulic cylinders, due to their considerable length, are prone to malfunctions, such as oil leaks caused by worn seals and bending deformation of the piston rod. These problems not only affect unloading efficiency but also increase maintenance costs and downtime. Furthermore, the hydraulic cylinder system has a relatively complex structure, making maintenance and upkeep more difficult. Utility Model Content

[0003] The purpose of this utility model is to provide a spiral-driven, horizontally moving garbage transfer vehicle to solve the above-mentioned problems, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a spiral-driven, horizontally moving garbage transfer vehicle, comprising several lead screws and a vehicle body. The lead screws are rotatably connected inside the vehicle body along its length. A push plate is slidably connected inside the vehicle body. The lead screws are threadedly connected to the push plate. The push plate is perpendicular to the bottom of the vehicle body. A drive assembly is fixedly connected to the outside of the vehicle body for simultaneously rotating all the lead screws.

[0006] The aforementioned spiral-driven translational garbage transfer vehicle uses a drive assembly to rotate all the lead screws. The multiple lead screws work together to drive the push plate thread, causing the push plate to move along the length of the vehicle. The push plate can push the goods out of the vehicle.

[0007] Preferably, one end of the lead screw is rotatably connected to the side wall of the carriage near the front of the carriage and passes through the carriage, while the other end of the lead screw is rotatably connected to a bearing seat, which is fixedly connected to the inner wall of the carriage.

[0008] Preferably, the lead screw surface is threaded with a threaded sleeve, which penetrates the push plate and is fixedly connected to the push plate.

[0009] Preferably, a sealing frame is fixedly connected to the edge of the push plate, and the sealing frame is fitted with the inner wall of the carriage with a clearance.

[0010] Preferably, the sealing frame is made of rubber, and a fixing bracket is fixedly connected to the surface of the push plate.

[0011] Preferably, a protective component is fixedly connected inside the carriage to cover the lead screw and prevent materials from wrapping around it.

[0012] Preferably, the protective assembly includes strip covers of the same number as the lead screw, the strip covers being fixedly connected to the carriage to cover the lead screw, and the strip covers being slidably connected to the push plate through the push plate.

[0013] Preferably, the drive assembly is located on the side of the carriage surface corresponding to the front of the vehicle.

[0014] Preferably, the drive assembly includes a rotating shaft, a sprocket one is fixedly connected to the portion of the lead screw that passes through the carriage, the rotating shaft is rotatably connected to the carriage, a sprocket two is fixedly connected to the rotating shaft, the sprocket one and the sprocket two are connected by chain drive, a torque motor is fixedly connected to the carriage, and the output shaft of the torque motor is fixedly connected to the end of the rotating shaft.

[0015] Preferably, the second sprocket is positioned between the four first sprockets and is used to tension the chain.

[0016] The beneficial effects are:

[0017] 1. By rotating all the lead screws through the drive assembly, the multiple lead screws cooperate to drive the push plate thread, so that the push plate moves along the length of the carriage. The push plate can push the goods out of the carriage. The use of lead screw to drive the push plate instead of hydraulic cylinder drive avoids the failures that are prone to occur due to the excessive length of hydraulic cylinder, such as oil leakage and piston rod bending. This improves the stability and reliability of the unloading device and reduces maintenance costs and downtime.

[0018] 2. The screw-driven push plate has a relatively simple structure and fewer parts, which reduces the difficulty of manufacturing and maintenance, and also reduces the space occupied in the carriage. The drive component is set on the side of the carriage surface corresponding to the front of the truck, which makes reasonable use of the idle space of the truck. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1-6 As shown, this utility model provides a spiral-driven translational garbage transfer vehicle, including several lead screws 1 and a vehicle body 3. The lead screws 1 are rotatably connected to the inside of the vehicle body 3 along the length direction of the vehicle body 3. A push plate 5 is slidably connected inside the vehicle body 3. The lead screws 1 and the push plate 5 are threadedly connected. The push plate 5 is perpendicular to the bottom of the vehicle body 3. A drive assembly 2 is fixedly connected to the outside of the vehicle body 3 for simultaneously rotating all the lead screws 1.

[0030] As an optional implementation, one end of the lead screw 1 is rotatably connected to the side wall of the carriage 3 near the front of the carriage and passes through the carriage 3. The other end of the lead screw 1 is rotatably connected to a bearing seat 4, which is fixedly connected to the inner wall of the carriage 3. There are four lead screws 1, which are distributed in the corners of the inner wall of the carriage 3.

[0031] The lead screw 1 has a threaded sleeve 9 on its surface, which passes through the push plate 5 and is fixedly connected to the push plate 5.

[0032] When the lead screw 1 rotates, it can push the push plate 5. The push plate 5 can not only push the garbage out of the carriage 3, but also cooperate with the inner wall of the carriage 3 to compress the garbage, thereby increasing the garbage loading capacity.

[0033] A sealing frame 8 is fixedly connected to the edge of the push plate 5. The sealing frame 8 is fitted with the inner wall of the carriage 3 with a clearance. The sealing frame 8 is made of rubber. A fixing bracket 10 is fixedly connected to the surface of the push plate 5. The sealing frame 8 can improve the matching degree between the push plate 5 and the inner wall of the carriage 3 and prevent material leakage.

[0034] A protective component 6 is fixedly connected inside the carriage 3 to cover the lead screw 1 and prevent materials from wrapping around the lead screw 1.

[0035] The protective component 6 includes a number of strip covers 7 equal to the number of lead screw 1. The strip covers 7 are fixedly connected to the carriage 3 and are used to cover the lead screw 1. The strip covers 7 pass through the push plate 5 and are slidably connected to the push plate 5. The strip covers 7 can prevent heavy materials such as stones from contacting the lead screw 1 and abrading the surface of the lead screw 1. At the same time, the strip covers 7 can also guide the push plate 5 and improve its movement stability.

[0036] The drive assembly 2 is located on the side of the carriage 3 corresponding to the front of the vehicle, which makes good use of the idle space of the truck.

[0037] The drive assembly 2 includes a rotating shaft 14. A sprocket 12 is fixedly connected to the part of the lead screw 1 that passes through the carriage 3. The rotating shaft 14 is rotatably connected to the carriage 3. A sprocket 2 15 is fixedly connected to the rotating shaft 14. The sprocket 12 and the sprocket 2 15 are connected by a chain 13. A torque motor 11 is fixedly connected to the carriage 3. The output shaft of the torque motor 11 is fixedly connected to the end of the rotating shaft 14. The rotating shaft 14 and the sprocket 2 15 are rotated by the torque motor 11. The sprocket 2 15 cooperates with the chain 13 and the sprocket 12 to rotate the entire lead screw 1 at the same time.

[0038] The second sprocket 15 is positioned between the four first sprockets 12 to tension the chain 13, thus ensuring the stability of the engagement between the chain 13 and the first sprockets 12 and the second sprocket 15.

[0039] With the above structure, the drive assembly 2 rotates all the lead screws 1, and the multiple lead screws 1 cooperate with each other to drive the push plate 5 threadedly, so that the push plate 5 moves along the length of the carriage 3, and the goods can be pushed out of the carriage 3 by the push plate 5.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
