Description

Technical Field

[0001] This invention relates to the field of building material loading devices, and particularly to a small material loading device for building construction. Background Technology

[0002] In the process of building houses, building materials such as sand and gravel are generally required. Since sand and gravel are piled up in a centralized manner at the construction site, they need to be manually transported to the mixing and processing container when used. Because this transportation process is time-consuming and labor-intensive, a small loading device is proposed for the transfer of sand and gravel.

[0003] A material loading device for building construction, disclosed in CN111392398A, includes a platform, side support plates, a bucket, a funnel, and a connecting block. Two side support plates are symmetrically installed on both sides of the upper surface of the platform. The material loading device of this invention is inexpensive to manufacture, compact, and convenient to use. It can be operated by only one person to achieve automatic material loading, saving physical strength. The material loading action can be completed by simply pushing and pulling, and the material loading can be completed efficiently in a short time, greatly saving labor and time costs. The aforementioned existing technical solutions have the following shortcomings: During operation, the device requires tilting the bucket for transport. The bucket is hinged to the outside of the swing shaft. Although guide blocks tip excess material during transport to ensure stability, the lack of a forced fixing structure between the bucket and the swing shaft, coupled with the swing shaft's movement and the entire device's backward movement, inevitably causes the bucket to sway during transport. Furthermore, the open shape of the bucket makes it prone to leakage due to the shaking, affecting the amount of material transported per batch and thus work efficiency. Finally, the device transfers material downwards to a container via a funnel, meaning the container needs to be placed on a platform beforehand. This necessitates manual labor to move and transport the material, the device as a whole, and the container simultaneously, making its operation quite labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a small material loading device for building construction, in order to solve the problem mentioned in the background art that the existing stainless steel composite slab welding device is not easy to automatically calibrate the billet, resulting in a large number of welding operation steps.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a small material loading device for house construction, comprising a support base, guide rails installed at both ends of one side of the support base, and a limiting slide plate connected between the guide rails; a second limiting guide hole is provided inside the limiting slide plate; a support plate is installed on one side of the support base, and an electric telescopic rod is installed on one side of the support plate; one end of the electric telescopic rod is connected to one side of the limiting slide plate; a first limiting guide hole is provided inside the support base, and a support rod passes through between the first and second limiting guide holes; the cross-section of the first limiting guide hole is inclined, and the height of the first limiting guide hole is lower on the side closer to the material; a transfer box is installed at one end of the support rod, and L-shaped limiting plates are installed on both sides of one end of the transfer box. A front baffle is connected between the L-shaped limiting plates. A rotating shaft is installed at the top of the transfer box via two support blocks, and a winding drum is sleeved on the outside of the rotating shaft. A guide rod is installed at the top of the transfer box between the rotating shaft and the front baffle, and a connecting rope passes through the top of the guide rod. One end of the connecting rope is connected to the top of one side of the front baffle, and the other end of the connecting rope is connected to the outside of the winding drum. Gears are installed on both sides of the rotating shaft, and a sliding tooth plate meshes with one side of each gear. The sliding tooth plate and the transfer box form an up-and-down sliding structure through the action of guide blocks and guide grooves. A rear baffle is installed at the other end of the transfer box, and sliding grooves are opened on both sides of the rear baffle near the transfer box. A slider is installed inside each sliding groove, and one side of the slider is connected to one side of the transfer box.

[0006] Preferably, the transfer box has a loading channel inside, and the bottom surface of the channel is inclined, with the side of the bottom surface of the channel closer to the rear baffle being lower.

[0007] Preferably, the height of the guide rod is adapted to the height of the loading channel of the transfer box, and the length of the sliding toothed plate is greater than twice the height of the transfer box. When the bottom end of the sliding toothed plate is level with the bottom end of the transfer box, the front baffle rises to the highest point.

[0008] Preferably, the rear baffle has a U-shaped cross-section, and the top of the transfer box on both sides of the top of the rear baffle is equipped with a fixing block, and the fixing block is connected to the rear baffle by a self-locking mechanism.

[0009] Preferably, the self-locking mechanism includes a spring, an unlocking plate, a self-locking block, and a positioning hole;

[0010] The spring is installed on one side inside the fixed block;

[0011] The unlocking plate is pressed against one end of the spring, and the top of the unlocking plate extends above the fixing block;

[0012] The self-locking plug is installed at one end of the unlocking plate, and the other end of the self-locking plug extends to the outside of the fixing block;

[0013] The positioning hole is located at the top of the rear baffle, and when the rear baffle is closed to the transfer box, the position of the positioning hole corresponds to the position of the self-locking block.

[0014] Preferably, there are two unlocking plates, and a connecting plate connects the two unlocking plates. A stop bar is installed on one side of the support base of one side of the unlocking plate. During the movement of the transfer box, the unlocking plate moves synchronously and contacts the stop bar. Under the obstruction of the stop bar, the unlocking plate moves horizontally.

[0015] Preferably, the cross-section of the self-locking block is a right-angled trapezoidal structure with its inclined surface facing downwards. When the rear baffle rises, its top end contacts the inclined surface of the self-locking block to push the self-locking block to move to the left.

[0016] Preferably, the transfer box has an L-shaped cross-section, and positioning bolts are installed on the outer side of the bottom end of the transfer box, with the bottom end of the positioning bolts penetrating into the foundation. Positioning forks are evenly installed on the bottom end of the transfer box on one side of the positioning bolts.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the small material loading device for house construction, through the up and down movement of the sliding toothed plate and the gravity of the sliding toothed plate, enables the transfer box to automatically close the front baffle during the material transfer process, thereby ensuring that the transfer box is closed and sealed to prevent the material from spilling during the transfer process.

[0018] 1. Through the meshing action between the sliding toothed plate and the gear, when the transfer box is on the ground, its sliding toothed plate is pushed upward by the ground, thereby causing the winding drum to rotate and wind up the connecting rope. Then, the connecting rope, together with the guide rod, pulls the front baffle to realize the automatic opening of the front baffle, making it convenient for individuals to sweep sand and gravel into the interior of the transfer box. During the upward movement of the transfer box, under the action of gravity, the front baffle and the sliding toothed plate fall downward, causing the winding drum to release the connecting rope to realize the automatic closing of the front baffle. Under the action of the guide block and the guide groove, the falling distance of the sliding toothed plate is ensured, thereby ensuring that the closed position of the front baffle corresponds to the opening position of the transfer box. At the same time, combined with the action of the rear baffle, the transfer box is kept closed during the transfer process. On the one hand, it prevents the transfer box from shaking due to external forces and causing sand and gravel leakage. On the other hand, it prevents sand and gravel from flying outward in windy weather, avoiding accidental injury to surrounding workers.

[0019] By moving the limiting slide plate left and right, the second limiting guide hole and the first limiting guide hole limit and guide the position of the support rod, so as to ensure that the transfer box can run from the ground to the top of the container, thereby further ensuring the automatic opening and closing of the front baffle. In addition, under the special loading channel, when the rear baffle is opened, the sand and gravel can be automatically poured down through the inclined channel to avoid the transfer box from overturning, thereby further improving the stability of the transfer box transmission.

[0020] 2. The self-locking block and the positioning hole work together to fix the position of the rear baffle, thus ensuring that sand and gravel will not leak during the loading process of the transfer box. At the same time, the blocking bar obstructs the movement of the unlocking plate, enabling the unlocking plate to move horizontally. When the transfer box moves to the highest point, its self-locking block automatically moves out of the positioning hole, thereby automatically opening the rear baffle to facilitate the automatic unloading of sand and gravel inside the transfer box, further reducing the number of manual operation steps and the intensity of operation.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0031] Please see Figures 1-7The present invention provides a small material loading device for house construction, including a support base 7. Guide rails 23 are installed at both ends of one side of the support base 7, and a limiting slide plate 18 is connected between the guide rails 23. A second limiting guide hole 17 is provided inside the limiting slide plate 18. A support plate 19 is installed on one side of the support base 7, and an electric telescopic rod 22 is installed on one side of the support plate 19. One end of the electric telescopic rod 22 is connected to one side of the limiting slide plate 18. A first limiting guide hole 8 is provided inside the support base 7. A support rod 16 passes through the first limiting guide hole 8 and the second limiting guide hole 17. The cross-section of the first limiting guide hole 8 is inclined, and the height of the first limiting guide hole 8 is lower on the side closer to the material. A transfer box 1 is installed at one end of the support rod 16. The transfer box 1 has a loading channel inside, and the bottom surface of the channel is inclined, with the bottom surface of the channel being lower on the side closer to the rear baffle 10. L-shaped limiting plates 2 are installed on both sides of one end of the transfer box 1, and a front baffle 3 is connected between the L-shaped limiting plates 2. The top of the transfer box 1 is open to the material. A rotating shaft 6 is installed on two support blocks, and a winding drum 24 is sleeved on the outside of the rotating shaft 6. The cross-section of the transfer box 1 is L-shaped. Positioning bolts 20 are installed on the outer side of the bottom of the transfer box 1, and the bottom ends of the positioning bolts 20 penetrate into the foundation. Positioning forks 21 are evenly installed on the bottom of the transfer box 1 on one side of the positioning bolts 20. A guide rod 4 is installed on the top of the transfer box 1 between the rotating shaft 6 and the front baffle 3, and a connecting rope 5 passes through the top of the guide rod 4. The height of the guide rod 4 is the same as the height of the loading channel of the transfer box 1. The sliding toothed plate 26 is longer than twice the height of the transfer box 1. When the bottom end of the sliding toothed plate 26 is level with the bottom end of the transfer box 1, the front baffle 3 rises to the highest point. One end of the connecting rope 5 is connected to the top of one side of the front baffle 3, and the other end of the connecting rope 5 is connected to the outside of the winding drum 24. Gears 25 are installed on both sides of the rotating shaft 6, and the sliding toothed plate 26 is meshed on one side of each gear 25. The sliding toothed plate 26 and the transfer box 1 form an up-and-down sliding structure through the action of the guide block and the guide groove.

[0032] In this embodiment, the transfer box 1 is placed between the sand and gravel to be transported and the container, the positioning fork 21 is inserted into the foundation, and the positioning bolts 20 are used to lock the transfer box 1 to the foundation to ensure the support stability of the transfer box 1 and prevent it from tipping over during the transfer process. In the initial state, the transfer box 1 is at the bottom. The workers can sweep the sand and gravel to directly sweep it into the interior of the transfer box 1, thereby activating the electric telescopic rod 22 to shorten it, which pulls the limiting slide plate 18 closer to the object. Since the support rod 16 is located inside the second limiting guide hole 17 and the first limiting guide hole 8, and the first limiting guide hole 18 is located inside the second limiting guide hole 17, the first limiting guide hole 18 is located inside the first limiting guide hole 18. The guide hole 8 is inclined, which causes the support rod 16 to move upward at an angle, lifting the transfer box 1. During the lifting process of the transfer box 1, under the action of gravity, the front baffle 3 and the sliding toothed plate 26 move downward, causing the sliding toothed plate 26 to mesh with the gear 25 to rotate, causing the winding drum 24 to unload the connecting rope 5. Then, the front baffle 3 automatically closes the feed opening of the transfer box 1, thereby preventing the sand and gravel from overflowing during the transfer process, ensuring the quality of sand and gravel transportation. Moreover, this transfer method reduces the direct handling of materials by workers. Its operation is simple and convenient, reducing the labor intensity of workers and achieving a labor-saving effect. Example

[0033] This embodiment differs from Embodiment 1 in that: a rear baffle 10 is installed at the other end of the transfer box 1, and grooves 11 are provided on both sides of the rear baffle 10 near the transfer box 1. Slider blocks 12 are installed inside each groove 11, and one side of each slider 12 is connected to one side of the transfer box 1. The rear baffle 10 has a U-shaped cross-section, and fixing blocks 13 are installed on the top sides of the transfer box 1 corresponding to the top sides of the rear baffle 10. A self-locking mechanism 14 is connected between the fixing blocks 13 and the rear baffle 10. The self-locking mechanism 14 includes a spring 1401, an unlocking plate 1402, a self-locking insert 1403, and a positioning hole 1404. The spring 1401 is installed inside one side of the fixing block 13. The unlocking plate 1402 is pressed against one end of the spring 1401, and the top of the unlocking plate 1402 extends above the fixing block 13. The self-locking insert 1403 is installed on the unlocking plate 1402. One end of the self-locking plug 1403 extends to the outside of the fixing block 13; the positioning hole 1404 is opened at the top inside the rear baffle 10, and when the rear baffle 10 is closed to the transfer box 1, the position of the positioning hole 1404 corresponds to the position of the self-locking plug 1403; there are two unlocking plates 1402, and a connecting plate 15 is connected between the two unlocking plates 1402; a stop bar 9 is installed on one side of the support seat 7 on one side of the unlocking plate 1402; during the movement of the transfer box 1, the unlocking plate 1402 moves synchronously and contacts the stop bar 9; under the obstruction of the stop bar 9, the unlocking plate 1402 moves horizontally; the cross section of the self-locking plug 1403 is a right trapezoidal structure, and its inclined surface faces down; when the rear baffle 10 rises, its top end contacts the inclined surface of the self-locking plug 1403 to push the self-locking plug 1403 to move to the left.

[0034] In this embodiment, the self-locking mechanism 14 moves synchronously as the transfer box 1 moves upward at an angle. Before the transfer box 1 reaches its highest point, its stop bar 9 contacts and blocks the unlocking plate 1402 on the inner side, preventing the unlocking plate 1402 from moving synchronously with the transfer box 1. This causes the self-locking block 1403 to move relative to the transfer box 1, moving it to the left and compressing the spring 1401. Consequently, the self-locking block 1403 moves out of the positioning hole 1404. When the transfer box 1 reaches its highest point, the rear baffle 10 slides down to its lowest point, automatically opening the discharge opening of the transfer box 1. This allows the sand and gravel to slide directly out of the transfer box 1 and fall into the container below under the action of the inclined plane, thus achieving automatic unloading of the sand and gravel. This device reduces the number of control operations required by workers for sand and gravel transport, improving their work efficiency. As the transfer box 1 falls back to the ground, the foundation obstructs the rear baffle 10, causing it to move upwards. The top of the rear baffle 10 contacts the inclined surface of the self-locking block 1403, causing the self-locking block 1403 to move to the left and automatically rebound under the action of the spring 1401, thus automatically locking the rear baffle 10 to prevent sand and gravel from spilling out during the loading process. The entire device has a high degree of automation, and the opening and closing of the inlet and outlet are automatically coordinated with the automatic positioning of the transfer box 1. At the same time, this device reduces the number of steps and the difficulty of operation for workers handling sand and gravel, which helps to improve the overall construction efficiency.
