Technical Field

[0001] This utility model belongs to the technical field of transfer devices, and in particular relates to a raw material transfer device for concrete production. Background Technology

[0002] Cement concrete: refers to a general term for engineering composite materials made by mixing cement, sand, stone, etc. with water to form a whole. The term concrete usually refers to cement concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (with or without admixtures and additives) in a certain proportion, and then mixing, molding and curing it. It is also called ordinary concrete. It is widely used in civil engineering. During the production of cement concrete, raw material transfer devices are required.

[0003] To address this, Chinese Patent CN216301161U discloses a raw material transfer device for cement concrete production, comprising a box body with push plates fixedly connected to both the front and rear ends of the top left side of the box body. A first spring, clamping plate, pull rod, pull ring, second spring, buffer plate, sliding sleeve, sliding rod, third spring, buffer block, fourth spring, fixing block, buffer column, moving wheel, anti-slip pad, first sliding groove, first sliding block, second sliding groove, and second sliding block cooperate to achieve the advantages of clamping and limiting while providing elastic buffering. This allows for clamping and limiting of bagged cement raw materials during transportation, while simultaneously providing elastic buffering and shock absorption for the raw material transfer device, preventing waste of bagged cement raw materials and reducing production costs.

[0004] However, the aforementioned device still requires manual handling of bagged cement from high to low during unloading, which is inconvenient for emptying the bagged cement all at once, is laborious and time-consuming, and thus affects the efficiency of the transfer. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a raw material transfer device for concrete production. It features a pressure plate for quickly compressing and releasing bagged cement, a protective insert for multi-directional limiting protection to prevent detachment during transport and enhance safety, and an adjustable tray for flexible tilting, allowing for one-time unloading of bagged cement. This saves time and effort and effectively improves transfer efficiency. It solves the problem in the prior art where unloading requires manual handling of bagged cement from high to low, making one-time unloading inconvenient, labor-intensive, and time-consuming, thus affecting transfer efficiency.

[0006] This utility model is implemented as follows: a raw material transfer device for concrete production includes a platform, one end of which is fixedly connected to a handrail. A rotating rod is connected to the top end of the platform via a bearing. A threaded rod is fixedly sleeved in the middle of the rotating rod. A pressure plate that can move up and down is sleeved on the threaded rod. Protective inserts are inserted through the top of the front, back, and right sides of the pressure plate. An adjusting support plate is located directly below the pressure plate. One end of the adjusting support plate is rotatably mounted on the top of the platform. An adjusting slider is slidably connected to the bottom of the adjusting support plate. A crossbar is hinged to the bottom of the adjusting slider. The end of the crossbar extends to the other end of the adjusting support plate and is fixedly connected to a lifting ring. The lifting ring is threaded onto the threaded rod and moves up and down along the threaded rod and the rotating rod.

[0007] In a preferred embodiment of this utility model, a motor is fixedly connected to the bottom of the vehicle platform, the output end of the motor is fixedly connected to the lower end of the rotating rod, a guide rod is fixedly connected to the top of the vehicle platform, a lifting plate and a guide plate are fixedly connected to the left side of the pressure plate, the lifting plate is threaded onto the threaded rod, and the guide plate is slidably sleeved onto the guide rod.

[0008] With this setup, the motor drives the rotating rod to rotate the threaded rod, which facilitates the up-and-down movement of the lifting plate, and in turn, the up-and-down movement of the pressure plate. The guide plate slides on the guide rod to guide the movement, ensuring the smooth lifting and lowering of the pressure plate. This allows for the rapid pressing and loosening of bagged cement without manual operation, saving manpower and enabling quick adjustments, thus improving transfer efficiency.

[0009] As a preferred embodiment of this utility model, a baffle is fixedly connected to the top of the rotating rod, and a first spring is fixedly connected between the baffle and the lifting plate. The first spring is sleeved on the rotating rod and the threaded rod.

[0010] This design facilitates the elastic extension and retraction of the lifting plate, which in turn facilitates the elastic extension and retraction of the pressure plate. This allows the pressure plate to stably disengage from the threaded rod and enter the rotating rod, as well as disengage from the rotating rod and enter the threaded rod, making it convenient to use. At the same time, the first spring also acts as a buffer, preventing excessive impact on the cement bag when the pressure plate descends, thus protecting the cement bag and the cement inside from damage.

[0011] In a preferred embodiment of this utility model, two support blocks are fixedly connected to the top of the vehicle board, and a support rod is inserted through the support blocks. A sliding hole is provided on the support block, and both ends of the support rod slide along the sliding hole. Both ends of the support rod are fixedly connected to the bottom of the sliding hole through rubber cylinders. One end of the adjusting plate is slidably sleeved on the middle of the support rod, and a second spring is fixedly connected to the bottom of the other end of the adjusting plate. The end of the second spring is fixedly connected to the vehicle board.

[0012] This design allows for easy adjustment of the pallet's rotational mounting on the top of the truck bed, providing a degree of elastic support. When the lifting ring moves the crossbar and adjusting slider, one end of the pallet rotates while the other end rises, enabling flexible adjustment of the pallet's tilt angle. This facilitates the one-time unloading of bagged cement, eliminating the need for manual handling and saving time and effort, thus significantly improving unloading efficiency and overall transport efficiency. Furthermore, the second spring and rubber cylinder provide elastic support to the bottom of the pallet, making it convenient to use.

[0013] In a preferred embodiment of this utility model, the bottom of the adjusting plate is provided with a sliding groove, and both sides of the sliding groove are provided with limiting grooves. The adjusting slider slides along the sliding groove, and both sides of the adjusting slider are fixedly connected to limiting sliders, which move along the limiting grooves.

[0014] With this setting, the adjusting slider slides in the chute, and the limiting slider moves in the limiting groove, which limits and guides the adjusting slider, ensuring that the adjusting slider slides stably along a straight line. This makes the tilt adjustment of the adjusting tray more stable and reliable, avoids shaking or deviation, and ensures the smooth progress of the unloading process.

[0015] As a preferred embodiment of this utility model, a stop block is fixedly connected to the top of the protective insert plate, a weight reduction hole is opened in the middle of the protective insert plate, a positioning plate is fixedly connected to the bottom of the protective insert plate, and magnetic sheets are fixedly connected to the corresponding surfaces between the positioning plate and the pressure plate, and the magnetic sheets are attracted and fixed to each other.

[0016] This design reduces the weight of the protective insert, facilitating operation. The magnetic plates attract each other, ensuring a secure connection between the protective insert and the pressure plate. When the pressure plate presses down on the top of the bagged cement, pushing the protective insert downwards separates the magnetic plates, allowing it to slide down to the front, back, and other positions on the bagged cement. This facilitates containment protection around the bagged cement, further preventing it from falling out and becoming unstable, enhancing safety during transportation, and making the protective insert easy to use and quickly return to its original position. The design is flexible and easy to operate.

[0017] In a preferred embodiment of this invention, the pressure plate has an insertion hole, the protective insert plate slides along the insertion hole, and the adjusting support plate has a positioning groove, with the positioning groove and the positioning plate being matched and connected.

[0018] With this design, the protective insert can be flexibly inserted and removed along the insertion hole, making it easy to adjust the protection range according to actual needs. The positioning groove and positioning plate work together to further fix the position of the protective insert, enhance the stability of the protective insert after installation, and ensure that the protective insert can always effectively protect the cement bag during transportation, preventing the cement bag from slipping or scattering.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The pressure plate can quickly compress and loosen bagged cement, which is convenient to use and saves manpower. The protective insert plate, through the cooperation of magnetic pieces, positioning grooves, positioning plates and insertion holes, is easy to insert and remove and quickly return to its original position. It is flexible in operation and realizes multi-directional limiting protection for bagged cement to prevent it from falling off during transportation, effectively enhancing the safety of the transfer process. In addition, the adjustable tray can be flexibly adjusted to tilt, so that the bagged cement can be poured out at one time during unloading, saving time and effort and effectively improving the transfer efficiency.

[0027] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] refer to Figures 1 to 6As shown in the figure, a concrete production raw material transfer device provided by this utility model includes a platform 1. One end of the platform 1 is fixedly connected to a handrail 101. The top end of the platform 1 is connected to a rotating rod 2 via a bearing. A threaded rod 205 is sleeved and fixed in the middle of the rotating rod 2. A pressure plate 3 that can move up and down is sleeved on the threaded rod 205. Protective inserts 4 are inserted through the top of the front, back and right sides of the pressure plate 3. An adjusting support plate 5 is provided directly below the pressure plate 3. One end of the adjusting support plate 5 is rotatably installed on the top of the platform 1. An adjusting slider 602 is slidably connected to the bottom of the adjusting support plate 5. A crossbar 601 is hinged to the bottom of the adjusting slider 602. The end of the crossbar 601 extends to the other end of the adjusting support plate 5 and is fixedly connected to a lifting ring 6. The lifting ring 6 is threadedly sleeved on the threaded rod 205. The lifting ring 6 moves up and down along the threaded rod 205 and the rotating rod 2.

[0030] Specifically, a motor 201 is fixedly connected to the bottom of the vehicle plate 1, and the output end of the motor 201 is fixedly connected to the lower end of the rotating rod 2. A guide rod 202 is fixedly connected to the top of the vehicle plate 1. A lifting plate 301 and a guide plate 302 are fixedly connected to the left side of the pressure plate 3. The lifting plate 301 is threaded onto the threaded rod 205, and the guide plate 302 is slidably sleeved onto the guide rod 202.

[0031] Using the above scheme, the motor 201 drives the rotating rod 2 to rotate the threaded rod 205, which facilitates the up and down movement of the lifting plate 301, and in turn facilitates the up and down movement of the pressure plate 3. The guide plate 302 slides on the guide rod 202 to play a guiding role, ensuring the stability of the lifting of the pressure plate 3. It can quickly realize the pressing and loosening of bagged cement without manual operation, saving manpower and allowing for rapid adjustment, which helps to improve the transfer efficiency.

[0032] Specifically, a baffle 203 is fixedly connected to the top of the rotating rod 2, and a first spring 204 is fixedly connected between the baffle 203 and the lifting plate 301. The first spring 204 is sleeved on the rotating rod 2 and the threaded rod 205.

[0033] The above scheme facilitates the elastic extension and retraction of the lifting plate 301, which in turn facilitates the elastic extension and retraction of the pressure plate 3. This allows the pressure plate 3 to stably disengage from the threaded rod 205 and enter the rotating rod 2, and to disengage from the rotating rod 2 and enter the threaded rod 205. This makes it convenient to use. At the same time, the first spring 204 can also play a buffering role, preventing excessive impact on the cement bag when the pressure plate 3 descends, and protecting the cement bag and the cement inside from damage.

[0034] Specifically, two support blocks 102 are fixedly connected to the top of the vehicle platform 1, and a support rod 501 is inserted through the support blocks 102. A sliding hole 103 is provided on the support block 102, and both ends of the support rod 501 slide along the sliding hole 103. Both ends of the support rod 501 are fixedly connected to the bottom of the sliding hole 103 through a rubber cylinder 104. One end of the adjusting plate 5 is slidably sleeved on the middle of the support rod 501, and a second spring 502 is fixedly connected to the bottom of the other end of the adjusting plate 5. The end of the second spring 502 is fixedly connected to the vehicle platform 1.

[0035] The above scheme allows the adjustable pallet 5 to be easily mounted on the top of the vehicle platform 1 and provides a certain degree of elastic support. When the lifting ring 6 moves the crossbar 601 and the adjusting slider 602, one end of the adjustable pallet 5 rotates and the other end rises, enabling flexible adjustment of the tilt angle of the adjustable pallet 5. This facilitates the one-time dumping of bagged cement without the need for manual handling, saving time and effort and greatly improving unloading efficiency, thereby increasing the efficiency of the transfer work. Furthermore, the second spring 502 and the rubber cylinder 104 provide elastic support to the bottom of the adjustable pallet 5, making it convenient to use.

[0036] Specifically, the bottom of the adjusting plate 5 is provided with a sliding groove 503, and the two side walls of the sliding groove 503 are provided with limiting grooves 504. The adjusting slider 602 slides along the sliding groove 503, and the two sides of the adjusting slider 602 are fixedly connected with limiting sliders 603. The limiting sliders 603 move along the limiting grooves 504.

[0037] Using the above scheme, the adjusting slider 602 slides in the slide groove 503, and the limiting slider 603 moves in the limiting groove 504, which plays a limiting and guiding role for the adjusting slider 602, ensuring that the adjusting slider 602 slides stably along a straight line, making the tilt adjustment of the adjusting tray 5 more stable and reliable, avoiding shaking or deviation, and ensuring the smooth progress of the unloading process.

[0038] Specifically, a stop block 402 is fixedly connected to the top of the protective insert plate 4, a weight reduction hole 401 is opened in the middle of the protective insert plate 4, a positioning plate 403 is fixedly connected to the bottom of the protective insert plate 4, and magnetic pieces 404 are fixedly connected to the corresponding surfaces between the positioning plate 403 and the pressure plate 3, and the magnetic pieces 404 are attracted and fixed to each other.

[0039] By adopting the above scheme, the weight-reducing hole 401 reduces the weight of the protective insert plate 4, making it easier to operate. The magnetic pieces 404 attract each other, making the protective insert plate 4 firmly connected to the pressure plate 3. When the pressure plate 3 presses the top of the bagged cement, it pushes the protective insert plate 4 downward, causing the magnetic pieces 404 to separate. This allows the protective insert plate 4 to slide down to the front, back, and other positions of the bagged cement, thus facilitating the limiting protection around the bagged cement. This further prevents the bagged cement from falling off and becoming unstable, enhances the safety of the transportation process, facilitates the use and quick return of the protective insert plate 4, and makes the operation flexible.

[0040] Specifically, the pressure plate 3 has an insertion hole 303, the protective insertion plate 4 slides along the insertion hole 303, the adjusting support plate 5 has a positioning groove 505, and the positioning groove 505 and the positioning plate 403 are matched and connected.

[0041] Using the above scheme, the protective insert 4 can be flexibly inserted and removed along the insertion hole 303, which makes it easy to adjust the protection range according to actual needs. The positioning groove 505 and the positioning plate 403 cooperate to further fix the position of the protective insert 4, enhance the stability of the protective insert 4 after installation, and ensure that the protective insert 4 can always effectively protect the cement bag during transportation, preventing the cement bag from slipping or scattering.

[0042] The working principle of this utility model:

[0043] In use, place the bagged cement on the adjusting pallet 5, start the motor 201 to drive the rotating rod 2 to rotate, and the rotating rod 2 drives the threaded rod 205 to rotate, causing the lifting plate 301 to move the pressure plate 3 downward to a suitable distance, pressing and fixing the bagged cement. At this time, because the lifting ring 6 moves downward and disengages from the threaded rod 205 and moves onto the rotating rod 2, and the bottom of the adjusting pallet 5 is elastically supported by the second spring 502 and the rubber cylinder 104, the adjusting pallet 5 will stably support the bagged cement. Then push the protective insert 4 downward to limit and protect the bagged cement around it, and then push the cart 1 to transfer it. When unloading, the pressure plate 3 moves upward to release. The bagged cement is disengaged from the threaded section and moved to the upper end of the rotating rod 2. At this time, the lifting ring 6 also moves upward, causing the crossbar 601 to move upward and drive the adjusting slider 602 to move along the slide groove 503. This causes one end of the adjusting tray 5 to rotate around the support rod 501, while the other end is lifted, thus tilting the adjusting tray 5. This facilitates the one-time dumping of the bagged cement, saving time and effort and effectively improving the transfer efficiency. After unloading, the pressure plate 3 is pulled upward, so that the lifting plate 301 continues to remain at the upper end of the rotating rod 2. At this time, only the lifting ring 6 moves downward, which in turn drives the adjusting tray 5 to return to its original position. The motor 201 is then turned off, and the transfer is completed. The same operation is performed for the next operation.
