Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and in particular to a material turnover bin. Background Technology

[0002] Waste materials generated from traditional construction, such as concrete, construction waste, waste mortar, sand and gravel residues, and cement-based waste, will not only exacerbate the environmental burden if not scientifically disposed of, but will also generate high costs for waste collection and storage. However, by transforming these waste materials into standardized reusable materials, the waste materials can be reduced in quantity and significant economic value can be created.

[0003] In related technologies, the commonly used material turnover methods in construction mainly include manual scooping and lifting the entire container for dumping. Manual scooping is a traditional material turnover method that relies on operators using tools to scoop materials out of the container and transfer them to the target location. Lifting the entire container for dumping utilizes gravity to make the materials flow out automatically.

[0004] However, manual scooping and pouring are cumbersome and inefficient, making it difficult to meet the needs of large-scale construction. While lifting the entire bucket for pouring improves discharge efficiency, it easily generates a lot of dust during the pouring process, which seriously affects the air quality at the construction site and also increases the health risks for operators. Utility Model Content

[0005] To address the aforementioned problems, this application provides a material turnover bucket.

[0006] The material turnover bin provided in this application adopts the following technical solution:

[0007] A material turnover bin includes a frame, a bin body, a cap, a bin sleeve, and a drive cylinder. The bin body is fixed to the frame, and a discharge port is provided at the bottom of the bin body, with a certain distance reserved between the discharge port and the ground. The drive cylinder is vertically fixed to the top of the frame, and the piston rod of the drive cylinder is configured to extend vertically downward. The bin sleeve covers the bin body, and both the top and bottom of the bin sleeve are open. The cap is located below the discharge port and is used to cover the discharge port. The cap is fixedly connected to the bottom of the bin sleeve. The piston rod of the drive cylinder is fixedly connected to the upper edge of the bin sleeve. The extension and retraction of the piston rod of the drive cylinder drives the bin sleeve to move up and down. A material discharge outlet is provided on one side of the bin sleeve, and the material discharge outlet is provided with a movable opening door for closing the material discharge outlet.

[0008] By adopting the above technical solution, when not in discharge operation, the piston rod of the drive cylinder remains stationary, and the barrel sleeve and the cap maintain their initial positions. The cap is then positioned over the discharge port. During discharge operation, the piston rod of the drive cylinder extends downwards. Because the piston rod is fixedly connected to the upper edge of the barrel sleeve, the piston rod causes the barrel sleeve to move downwards. Since the cap is fixedly connected to the barrel sleeve, it further causes the cap to move downwards, thereby opening the discharge port. Material flows out of the discharge port into the barrel sleeve. When the barrel is moved, the movable opening door is pushed by the material. The extrusion mechanism automatically opens, allowing materials to be discharged from the material outlet. During the discharge process, operators only need to operate the drive cylinder to achieve automatic material discharge, realizing both automatic and semi-automatic discharge. This solves the problems of cumbersome operation and low efficiency of traditional manual scooping and pouring methods. At the same time, during the discharge process, the barrel sleeve is always in contact with the ground, covering the ground. The barrel sleeve forms a physical barrier that effectively reduces dust diffusion and also reduces the dust pollution and health risks caused by the overall lifting and pouring method. It is suitable for closed-loop turnover processing of dusty materials.

[0009] Preferably, a fixing rod is provided between the cap and the barrel sleeve. Several fixing rods are provided. One end of the fixing rod is fixedly connected to the cap, and the other end of the fixing rod is fixedly connected to the inner wall of the barrel sleeve. The fixing rod is horizontally arranged.

[0010] By adopting the above technical solution, the cap and the barrel sleeve are fixedly connected by multiple fixing rods, thereby fixing the position of the cap and ensuring that the cap rises and falls synchronously when the piston rod of the drive cylinder drives the barrel sleeve to rise and fall, so that the cap can accurately perform the action of closing the discharge port.

[0011] Preferably, the upper surface of the cover is provided with a relief groove, the internal shape of the relief groove matches the external shape of the outlet edge, and when the cover is closed on the outlet, the groove wall of the relief groove abuts against the outer wall of the outlet edge.

[0012] By adopting the above technical solution, the wall of the positioning groove abuts against the outer wall of the discharge port edge, forming a wrap-around fit. The wall of the positioning groove fits tightly against the outer wall of the discharge port edge, solving the gap between the traditional cover and the discharge port, reducing the occurrence of material overflowing from the gap. Even under vibration or tilting caused by the movement of the material turnover drum, the cover and the discharge port can maintain a stable fit.

[0013] Preferably, the movable opening door is hinged to the material outlet, and a limit block is provided on the upper side of the hinge point between the movable opening door and the material outlet, so that the movable opening door abuts against the limit block after opening and closing at a certain angle.

[0014] By adopting the above technical solution, the movable opening door abuts against the limiting block after opening and closing to a certain angle. The limiting block limits the maximum opening angle of the movable opening door, ensuring that the material can flow out at a stable and controllable speed during the pouring process, reducing the problem of material pouring too fast and scattering due to excessive opening angle.

[0015] Preferably, the bottom edge of the barrel sleeve is provided with a rubber sealing edge, which is fitted onto the bottom edge of the barrel sleeve.

[0016] By adopting the above technical solution, when the barrel sleeve comes into contact with surfaces of different roughness, such as concrete, asphalt, or gravel, the rubber sealing edge utilizes its own elastic deformation characteristics to increase the contact area between the barrel sleeve and the surface of different roughness, automatically adapt to the micro-unevenness of the surface, enhance the sealing performance when the bottom of the barrel sleeve comes into contact with the surface, further reduce dust diffusion, and at the same time, the elastic deformation of the rubber sealing edge has a buffering effect, which can extend the service life of the barrel sleeve.

[0017] Preferably, the upper surface of the barrel is provided with a feed inlet, the feed inlet is connected to the barrel, the feed inlet is provided with a barrel cover, the barrel cover is used to cover the feed inlet, and the side wall of the barrel cover is provided with a handle.

[0018] By adopting the above technical solution, the sealing of the bucket lid and the feed inlet reduces the moisture and contamination of materials during transportation or storage. The handle makes it easy for operators to pick up the bucket lid, making it suitable for continuous operation scenarios with frequent loading.

[0019] Preferably, the inner wall of the bucket lid is provided with a positioning groove, and the outer wall of the bucket body is provided with a positioning block, wherein the positioning groove and the positioning block are inserted into each other.

[0020] By adopting the above technical solution, the positioning block forms a mechanical limit on the barrel lid after being inserted into the positioning groove, realizing a stable connection between the barrel lid and the feed inlet, reducing the displacement of the barrel lid caused by external force, and guiding the operator to close the barrel lid at the correct angle.

[0021] Preferably, the four corners of the frame are provided with casters, and the casters are omnidirectional wheels.

[0022] The casters allow the material turnover bins to be moved flexibly on the construction site. Operators can quickly adjust the position of the bins with just a light push. The casters also have a braking function, which can fix the position after the bins are in place, reducing the slippage of the material turnover bins caused by external forces.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The piston rod of the drive cylinder is vertically fixed to the top of the frame. The extension and retraction of the piston rod of the drive cylinder drives the barrel sleeve to move up and down, and simultaneously controls the movement of the cover, so that the cover is separated from the discharge port. The material flows out from the discharge port at the bottom of the barrel and is poured out through the movable opening door. This solves the problems of cumbersome operation and low efficiency of the traditional manual scooping or pouring method. At the same time, the bottom edge of the barrel sleeve is close to the ground to form a physical barrier, which effectively inhibits the dust dispersion and replaces the dust pollution caused by the overall lifting and pouring of the barrel. This reduces the impact on the construction environment and realizes the closed and efficient turnover treatment of dusty materials. Operators only need to simply control the drive cylinder to complete the automatic discharge of materials.

[0025] 2. By setting a relief groove on the cover that matches the shape of the discharge port, the groove wall fits snugly against the outer edge of the discharge port. This effectively prevents material from overflowing from the gaps when the material turnover drum moves or vibrates, significantly improving the sealing stability during turnover.

[0026] 3. By setting a rubber sealing edge on the bottom edge of the barrel sleeve, the elastic deformation characteristics of the rubber sealing edge are used to adapt to different roughness surfaces and increase the contact area between the bottom edge of the barrel sleeve and the ground, thereby improving the dust suppression effect and extending the service life of the barrel sleeve through the buffering effect.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a material turnover bin. (Refer to...) Figure 1 and Figure 2A material turnover bin includes a frame 1, which includes four uprights 11 and a support frame 12. The four uprights 11 are fixedly connected to the four corners of the support frame 12. At the same time, each of the four uprights 11 is provided with a caster wheel 2. In this embodiment, the caster wheel 2 is set as a universal wheel, and the universal wheel is fixed to the lower surface of the four uprights 11.

[0034] To further explain, the casters drive the frame 1 to move the material turnover bucket further, allowing the material turnover bucket to move flexibly on the construction site. Operators only need to push the material turnover bucket lightly to quickly adjust the position of the bucket 3. In addition, the casters have a braking function, which can fix the position after the bucket 3 is in place, reducing the slippage of the material turnover bucket caused by external force.

[0035] Meanwhile, a material turnover bucket also includes a bucket body 3. Specifically, the bucket body 3 is fixed on the support frame 12. The upper surface of the bucket body 3 is provided with a feed inlet 31. The feed inlet 31 is vertically fixed on the upper surface of the support frame 12. The feed inlet 31 has a cylindrical structure. The feed inlet 31 is provided with a bucket cover 4, which is used to cover the feed inlet 31.

[0036] Furthermore, the internal structure of the lid 4 matches the external structure of the feed inlet 31. The inner wall of the lid 4 is provided with a positioning groove 41, and the corresponding position of the outer wall of the upper surface of the barrel 3 is provided with a positioning block 33. In this embodiment, there are three positioning grooves 41 and three positioning blocks 33. When the lid 4 closes the feed inlet 31, the positioning groove 41 and the positioning block 33 are inserted and engaged, and the groove wall of the positioning groove 41 abuts against the outer wall of the positioning block 33. At the same time, handles 42 are provided on both sides of the lid 4, and the handles 42 are fixedly connected to the lid 4.

[0037] This demonstrates that after the positioning block 33 is inserted into the positioning groove 41, it forms a mechanical limit on the lid 4, achieving a stable connection between the lid 4 and the feed inlet 31, reducing the offset of the lid 4, and guiding the operator to close the lid 4 at the correct angle. Furthermore, the closing of the lid 4 and the feed inlet 31 can reduce the moisture and contamination of materials during transportation or storage. The handle 42 makes it easy for the operator to pick up the lid 4, making it suitable for continuous operation scenarios with frequent loading.

[0038] Reference Figure 3 On the other hand, the material turnover barrel also includes a cover 5, a barrel sleeve 6, and a drive cylinder 7. The barrel sleeve 6 covers the barrel body 3, the drive cylinder 7 is located above the barrel sleeve 6 and is fixedly connected to the support frame 12, and the bottom of the barrel body 3 is also provided with a discharge port 32. The cover 5 is located below the discharge port 32 and is used to cover the discharge port 32. The cover 5 is fixedly connected to the bottom of the barrel sleeve 6, and the piston rod of the drive cylinder 7 is fixedly connected to the upper edge of the barrel sleeve 6.

[0039] Specifically, the barrel sleeve 6 has a cuboid structure, and both the upper and lower sides of the barrel sleeve 6 are open. The barrel sleeve 6 surrounds the barrel body 3, and the inner wall of the barrel sleeve 6 and the outer wall of the barrel body 3 are in clearance fit. A material discharge outlet 61 is provided on one side of the barrel sleeve 6. The material discharge outlet 61 is provided with a movable opening door 10. The movable opening door 10 is hinged to the upper edge of the material discharge outlet 61. A limit block 8 is provided on the upper side of the hinge between the movable opening door 10 and the material discharge outlet 61. The limit block 8 is fixedly connected to the outer wall of the barrel sleeve 6. When the movable opening door 10 is opened and closed at a certain angle, the movable opening door 10 abuts against the limit block 8.

[0040] Furthermore, in this embodiment, two drive cylinders 7 are provided, and two fixing rings 121 are provided on the upper surface of the support frame 12. The fixing rings 121 are located on both sides of the barrel body 3 and pass through the support frame 12. The drive cylinder 7 is fixed on the fixing rings 121. The piston rod of the drive cylinder 7 extends in the fixing rings 121 in a vertically downward direction and performs telescopic movement. The piston rod of the drive cylinder 7 is fixedly connected to the outer wall of the upper edge of the barrel sleeve 6.

[0041] Meanwhile, a discharge port 32 is provided at the bottom of the barrel body 3, and the cover 5 is located below the discharge port 32. The cover 5 is used to cover the discharge port 32. A fixing rod 13 is provided between the cover 5 and the barrel cover 4. In this embodiment, four fixing rods 13 are provided. One end of the fixing rod 13 is fixedly connected to the cover 5, and the other end of the fixing rod 13 is fixedly connected to the inner wall of the barrel sleeve 6. Both the fixing rod 13 and the cover 5 are horizontally arranged.

[0042] Reference Figure 4 In addition, the upper surface of the cover 5 is provided with a relief groove 51. The internal shape of the relief groove 51 matches the external shape of the discharge port 32. When the cover 5 covers the discharge port 32, the groove wall of the relief groove 51 abuts against the outer wall of the discharge port 32.

[0043] This explains that when not in discharge operation, the piston rod of the drive cylinder 7 remains stationary, and the barrel sleeve 6 and the cover 5 maintain their initial positions. The cover 5 is then placed over the discharge port 32. When in discharge operation, since the piston rod of the drive cylinder 7 is fixedly connected to the upper edge of the barrel sleeve 6, and the piston rod of the drive cylinder 7 extends vertically downward within the fixed ring 121, the piston rod of the drive cylinder 7 moves downward, causing the barrel sleeve 6 to move downward. Since the cover 5 is fixedly connected to the barrel sleeve 6, it further moves the cover 5 downward, thereby opening the discharge port 32. The material flows out from the discharge port 32. When the barrel body 3 is moved, the movable opening door 10 is automatically opened by the material, allowing the material to be poured out from the position of the movable opening door 10. This achieves automatic and semi-automatic discharge, solving the problems of cumbersome operation and low efficiency of traditional manual scooping and pouring methods.

[0044] At the same time, the piston rod of the drive cylinder 7 moves downward, causing the barrel sleeve 6 to move down. The barrel sleeve 6 contacts the ground and always covers the ground, forming a physical barrier that effectively reduces dust diffusion and also reduces dust pollution and health risks caused by the overall lifting and tilting method of the barrel 3. It is suitable for closed-loop turnover treatment of dusty materials. During the discharge process, the operator only needs to operate the drive cylinder 7 to realize the automatic discharge of materials.

[0045] To further explain, after the movable opening door 10 opens and closes to a certain angle, it abuts against the limiting block 8. The limiting block 8 limits the maximum opening angle of the movable opening door 10, ensuring that the material can flow out at a stable and controllable speed during the pouring process, reducing the problem of material pouring too fast and scattering due to excessive opening angle.

[0046] In addition, a rubber sealing edge 9 is provided at the bottom edge of the barrel sleeve 6. The rubber sealing edge 9 is fitted onto the bottom edge of the barrel sleeve 6 and is made of EPDM rubber. EPDM rubber has excellent wear resistance and elasticity and can resist ultraviolet rays, ozone and chemical corrosion, making it especially suitable for outdoor roads or concrete, asphalt or gravel surfaces that need to be exposed for a long time.

[0047] As the piston rod of the drive cylinder 7 moves downward, it causes the barrel sleeve 6 to move downward. When the barrel sleeve 6 comes into contact with ground surfaces of different roughness, the rubber sealing edge 9 utilizes its own elastic deformation characteristics to automatically adapt to the micro-unevenness of the ground surface, thereby increasing the contact area between the barrel sleeve 6 and ground surfaces of different roughness and further enhancing the dust suppression effect of the barrel sleeve 6. At the same time, the elastic deformation buffering effect of the rubber sealing edge 9 extends the service life of the barrel sleeve 6.

[0048] The implementation principle of a material turnover bucket in this application embodiment is as follows:

[0049] Operators load materials through the feed inlet at the top of the barrel. The barrel lid is precisely engaged with the positioning block on the outer wall of the feed inlet using a positioning groove, which forms a mechanical limit on the lid, reducing lid offset. It also guides the operator to close the lid at the correct angle. Furthermore, the lid's fit with the feed inlet reduces the risk of moisture and contamination of materials during transportation or storage. The handle makes it easy for operators to pick up the lid, making it suitable for continuous operation scenarios with frequent loading.

[0050] The material turnover bucket is pushed to the designated position by the casters at the bottom of the four pillars of the frame. After the brake function of the casters is locked, the displacement of the material turnover bucket is restricted. The operator starts the drive cylinder, and the piston rod of the drive cylinder presses down vertically, causing the bucket sleeve to move down as a whole. The bucket sleeve is pulled down synchronously by three fixed rods arranged in a triangle. The clearance groove of the cover disengages from the discharge port of the bucket body, and the material flows into the inside of the bucket sleeve from the discharge port. At this time, the movable opening door is automatically opened by the material. The limit block limits the maximum opening angle of the movable opening door to ensure that the material is discharged from the material discharge port at a controllable flow rate, reducing the scattering caused by excessive pouring.

[0051] At the same time, the piston rod of the drive cylinder presses down vertically, causing the entire barrel sleeve to move downward. Throughout the discharge process, the bottom of the barrel sleeve remains in contact with the ground, and the rubber sealing edge at the bottom edge of the barrel sleeve is in contact with the ground, increasing the contact area between the barrel sleeve and the ground and further reducing the spillage of dust inside the barrel sleeve.

[0052] After the material discharge is completed, the cylinder piston rod retracts, the barrel sleeve rises and drives the cap to reset and close the discharge port. When the rubber sealing edge leaves the ground, it returns to its original shape, and the turnover barrel is quickly transferred to the next work station by the casters, entering a new round of operation.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
