Description

Technical Field

[0001] The utility model relates to the technical field of building material transfer devices, and particularly relates to a transfer mechanism and a building material transfer device for filling and road construction. Background Technique

[0002] The building material transfer device for filling and road construction is an important and indispensable device in building construction. It is mainly used to transfer building materials from one position to the position required for filling and road construction.

[0003] In the prior art, a patent document with an application number of CN202321493577.1, which was examined and published by the State Intellectual Property Office of China, discloses an adjusting structure and a building material transfer device for civil engineering majors, including: a height adjusting plate, the height adjusting plate is movably inserted into the adjusting plate receiving groove, the adjusting plate receiving groove is opened on the top surface of the hopper, the bottom end of the height adjusting plate is fixed with a bottom plate, the bottom end of the bottom plate is fixed with a hanging ring and a spring, and the bottom end of the inner wall of the adjusting plate receiving groove is fixed with a barb; the beneficial effect is: an adjusting plate receiving groove is opened in the hopper, the height adjusting plate is inserted into the adjusting plate receiving groove, and a limiting mechanism is arranged at the bottom end of the height adjusting plate. When the height adjusting plate is not limited, its top end extends out of the adjusting plate receiving groove to increase the height of the hopper. When the height adjusting plate is limited, the top end of the height adjusting plate retracts into the adjusting plate receiving groove to reduce the height of the hopper. The height adjusting plate is a whole-piece return plate, and there is no gap between the side plates, so that while adjusting the height of the hopper, powder or liquid building materials will not leak out of the hopper.

[0004] However, in the prior art, the limiting mechanism of the height adjusting plate is realized by the hanging ring at the bottom end of the bottom plate and the barb in the adjusting plate receiving groove. The barb will undergo elastic deformation when hooking and releasing the hanging ring. During long-term use, the yield strength of the barb will decrease significantly, and then the elastic limit of the barb will decrease. When an external force is applied to the barb again to make it hook or release the hanging ring through deformation, the barb will undergo plastic deformation and cannot hook the hanging ring anymore, and the barb is fixed deep in the adjusting plate receiving groove and cannot be replaced. Content of the Utility Model

[0005] The purpose of the utility model is to provide a transfer mechanism and a building material transfer device for filling and road construction to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A transfer mechanism, including: a hopper, an adjusting plate receiving groove is opened at the top end of the hopper, a height adjusting plate is movably inserted into the adjusting plate receiving groove, a bottom plate is fixed at the bottom end of the height adjusting plate, a limiting groove is opened on the surface of the bottom plate, a limiting rod mounting hole is opened on the surface of the hopper, and one end of a limiting rod is movably inserted into the limiting rod mounting hole, and the other end of the limiting rod is movably inserted into the limiting groove.

[0007] Preferably, the limiting rod mounting hole communicates with the adjusting plate receiving groove, and the limiting groove and the limiting rod mounting hole are vertically distributed.

[0008] Preferably, a sleeve is mounted on the surface of the hopper by screws. The sleeve is arranged at the position where the limiting rod mounting hole is formed on the surface of the hopper. One end of the limiting rod is movably inserted into the sleeve, and a spring plate is fixed at the end of the limiting rod extending into the sleeve, and a pull rod is fixed at the other end of the spring plate.

[0009] Preferably, the end of the pull rod away from the spring plate is movably inserted into and extends out of the surface of the sleeve. A spring is sleeved on the rod body of the pull rod. One end of the spring abuts against the surface of the spring plate, and the other end of the spring abuts against the inner wall of the sleeve.

[0010] Preferably, a clamping groove mounting hole is formed at the top end of the sleeve. The clamping groove mounting hole is a "convex"-shaped groove body. A clamping groove is formed at the top end of the rod body of the pull rod. One end of a clamping rod is movably inserted into the clamping groove mounting hole, and the other end of the clamping rod is movably inserted into the clamping groove.

[0011] Preferably, a finger groove is formed on the part of the rod body of the pull rod extending out of the sleeve.

One end of a pull rod 10 away from the spring plate 9 is movably inserted into and extends out of a surface of a sleeve 8, a spring 11 is sleeved on a rod body of the pull rod 10, one end of the spring 11 abuts against a surface of the spring plate 9, the other end of the spring 11 abuts against an inner wall of the sleeve 8, and a slope is provided on a part of a rod body of the limit rod 7 movably inserted into the limit groove 5.

[0023] In actual use, when it is necessary to lower the height of the truck bed 1, press down the height adjustment plate 2. When the bottom end of the height adjustment plate 2 contacts the inclined surface of the limit rod 7, the limit rod 7 withdraws from the adjustment plate receiving groove 3. The movement of the limit rod 7 causes the spring plate 9 to slide away from the truck bed 1 in the sleeve 8, and the movement of the spring plate 9 compresses the spring 11. When the height adjustment plate 2 continues to move downward until the limit rod mounting hole 6 is aligned with the limit groove 5, the spring 11 pushes one end of the limit rod 7 into the limit groove 5 under its own elastic force, and the other end of the limit rod 7 stays in the limit rod mounting hole 6 to limit the bottom plate 4, so that the height adjustment plate 2 is maintained in the state of being retracted into the adjustment plate receiving groove 3 to achieve the purpose of lowering the height of the height adjustment plate 2; when it is necessary to release the limit on the bottom plate 4, just insert the finger into the finger groove 12, and then pull the pull rod 10 in the direction away from the truck bed 1. The movement of the pull rod 10 drives the limit rod 7 to move in the same direction through the spring plate 9, so that the limit rod 7 withdraws from the limit groove 5, and the limit on the bottom plate 4 can be released; when the spring 11 fails during long-term use, the sleeve 8 can be removed from the truck bed 1, and then the spring plate 9 and the pull rod 10 can be pulled out of the sleeve 8 to replace the spring 11.

[0024] Embodiment 2: On the basis of Embodiment 1, in order to achieve the state of maintaining the pull rod 10 pulled out of the sleeve 8 without always pulling the pull rod 10, a card slot mounting hole 14 is opened at the top end of the sleeve 8. The card slot mounting hole 14 is a "convex"-shaped groove body. A card slot 13 is opened at the top end of the rod body of the pull rod 10. One end of a card rod 15 is movably inserted into the card slot mounting hole 14, and the other end of the card rod 15 is movably inserted into the card slot 13. A finger groove 12 is opened on a part of the rod body of the pull rod 10 extending out of the sleeve 8.

[0025] After pulling the pull rod 10 out of the sleeve 8 until the card slot 13 is aligned with the card slot mounting hole 14, press down the card rod 15 so that the bottom end of the card rod 15 is inserted into the card slot 13, and the pull rod 10 can be maintained in the state of being pulled out of the sleeve 8, so as to achieve the state of maintaining the pull rod 10 pulled out of the sleeve 8 without always pulling the pull rod 10.

[0026] In actual use, when it is necessary to lower the height of the truck bed 1, press down the height adjustment plate 2. When the bottom end of the height adjustment plate 2 contacts the inclined surface of the limit rod 7, the limit rod 7 exits from the adjustment plate receiving groove 3. The movement of the limit rod 7 causes the spring plate 9 to slide away from the truck bed 1 in the sleeve 8, and the movement of the spring plate 9 compresses the spring 11. When the height adjustment plate 2 continues to move downward until the limit rod mounting hole 6 is aligned with the limit groove 5, the spring 11, under its own elastic force, pushes one end of the limit rod 7 into the limit groove 5, and the other end of the limit rod 7 stays in the limit rod mounting hole 6 to limit the bottom plate 4, so that the height adjustment plate 2 is maintained in the state of being retracted into the adjustment plate receiving groove 3 to achieve the purpose of lowering the height of the height adjustment plate 2; when it is necessary to release the limit on the bottom plate 4, just insert a finger into the finger groove 12 and then pull the pull rod 10 away from the truck bed 1. The movement of the pull rod 10 drives the limit rod 7 to move in the same direction through the spring plate 9, so that the limit rod 7 exits from the limit groove 5, and the limit on the bottom plate 4 can be released; when the spring 11 fails during long-term use, the sleeve 8 can be removed from the truck bed 1, and then the spring plate 9 and the pull rod 10 can be pulled out of the sleeve 8 to replace the spring 11; after pulling the pull rod 10 out of the sleeve 8 until the card slot 13 is aligned with the card slot mounting hole 14, press down the card rod 15 so that the bottom end of the card rod 15 is inserted into the card slot 13 to maintain the pull rod 10 in the state of being pulled out of the sleeve 8, so as to achieve the purpose of not always pulling the pull rod 10 when it is necessary to maintain the state of the pull rod 10 being pulled out of the sleeve 8.
