Description

Technical Field

[0001] The utility model belongs to the technical field of material receiving boxes, and in particular relates to a material receiving box which can be turned over automatically. Background Art

[0002] After the aluminum bars are sawed, the rod heads and tails need to be collected in the receiving box, and then returned to the smelting furnace from the receiving box for the second time. In the prior art, in order to facilitate the dumping of materials into the smelting furnace, the commonly used receiving boxes are mostly dustpan-shaped boxes welded with steel plates. The following problems exist in the use of the receiving boxes: 1. The dustpan-shaped receiving box has a smaller rod receiving capacity under the same volume. Under the same production volume, more dumping times are required, which is not conducive to reducing costs and improving efficiency; 2. During the dumping process, the receiving box needs to be controlled by a forklift. The tilt angle of the forklift spline is limited, which can easily cause the material receiving box to have an insufficient tilt angle and the rod head inside to be not completely dumped; 3. During the dumping process, in order to improve the dumping efficiency and ensure that the material is completely dumped out, it is often necessary to shake the forklift spline up and down. Due to the high temperature of the production environment, shaking the spline can easily cause damage to the forklift hydraulic system and may even cause the oil pipe to burst, which in turn causes a fire, and does not meet the requirements of safe production; 4. The dumping process requires a large workload for the forklift operator and has high requirements on the operator's operating level. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a material receiving box that can be automatically turned over, which specifically includes the following contents:

[0004] An automatically flippable material receiving box comprises a material receiving box body, an automatic flipping mechanism, and a hooking and chaining system;

[0005] The receiving box body is a box body that is wide at the top and narrow at the bottom and has a right-angled trapezoidal cross section. The side of the bottom of the box body close to the inclined surface of the box body is the first end, and the side opposite to the first end is the second end.

[0006] The automatic flipping mechanism includes a bracket and a rotation mechanism, the bracket includes a horizontal bracket and a longitudinal bracket, the horizontal bracket includes a first end and a second end, so that the second end of the bottom of the box is arranged above the horizontal bracket and the first end of the horizontal bracket is rotatably connected to the bottom of the box through the rotation mechanism, the rotation angle of the rotation mechanism is preferably 0-180 degrees in the counterclockwise direction (that is, the box can be flipped outward at most 180 degrees, which can be more convenient to reset), so that the inclined surface of the box faces outward and the vertical surface opposite to the inclined surface is arranged in the direction of the longitudinal bracket, and the distance between the rotation connection and the second end of the bottom of the box is less than the The second end of the horizontal bracket is connected to the bottom end of the longitudinal bracket, and the end of the second end of the horizontal bracket is further provided with two forklift sockets for being sleeved on the outside of the forklift spline to achieve connection with the forklift. Therefore, the size and shape of the forklift sockets must correspond to the forklift spline to ensure that the spline can be inserted without too much gap, so as to ensure the stability of the connection. Generally speaking, the size of the forklift socket can be slightly larger than the size of the spline.

[0007] The hook chain system includes a fixed block, a "T"-shaped hook rod, a control rod and a chain, and the fixed block is connected to the top end of the longitudinal bracket; the long side of the "T"-shaped hook rod is horizontal and the short side is vertically arranged, the end of the long side of the "T"-shaped hook rod is rotatably connected to the fixed block, and the lower end of the short side extends into the box body and contacts the side surface of the box body at the second end of the bottom of the box body; the control rod includes a vertical control rod and a transverse control rod, one end of the transverse control rod is fixedly connected to the bottom end of the vertical control rod, and the other end is rotatably connected to the fixed block; the transverse control rod can be arranged horizontally or laterally inclined, and can be specifically designed according to actual needs; the bottom end of the vertical control rod is also rotatably connected to the upper end of the short side of the "T"-shaped hook rod, and the bottom end of the vertical control rod and the upper end of the short side of the "T"-shaped hook rod can be directly rotatably connected or can be achieved by a connecting component; one end of the chain is connected to the vertical control rod.

[0008] Preferably, the control rod is an "L"-shaped control rod, the vertical control rod is the long side of the "L"-shaped control rod, and the transverse control rod is the long side of the "L"-shaped control rod. More preferably, it also includes an intermediate connecting rod, the upper end of which is rotatably connected to the right-angle end of the "L"-shaped control rod, and the lower end of which is rotatably connected to the upper end of the short side of the "T"-shaped hook rod. The rotational connection between the "T"-shaped hook rod, the intermediate connecting rod, and the "L"-shaped control rod can be achieved through an articulated seat, a pin, or other methods, and the present invention does not impose too many restrictions. The fixed block is used for fixing, while the T-shaped hook rod, intermediate connecting rod, and L-shaped control rod are used for transmission. When the chain pulls the long side of the L-shaped control rod, the L-shaped control rod rotates clockwise around the endpoint of the short side. At this time, its right-angled end is displaced upward, and the intermediate connecting rod pulls the T-shaped hook rod to rotate clockwise around the endpoint of the long side of the T-shaped hook rod. At this time, the lower end of the short side of the T-shaped hook rod is displaced upward, causing the lower end of the short side of the T-shaped hook rod to leave the box. The inside of the test box lacks obstruction and tends to flip toward the center of gravity. Therefore, the box flips toward the inclined surface around the rotating mechanism. In this way, the material receiving box can be automatically flipped. When the box needs to be reset, the entire device is gradually lowered until the lowest point of the box touches the bottom surface. The device is then lowered further, and the box rotates clockwise around the rotating mechanism until the second end of the bottom of the box returns to the upper end of the transverse support frame. The chain is then released, allowing the L-shaped control rod, the middle connecting rod, and the T-shaped hook rod to return to their original position. At this point, the lower end of the short side of the T-shaped hook rod returns to the box and presses against the side of the box to prevent it from rotating, completing the reset. The height of the entire device can be controlled by a forklift. The chain can be a soft rope, a hard rope, or a rod, and the specific method can be selected as needed. When using a soft rope, the pulling angle should not be too large (to ensure that the L-shaped control rod can be reset under the action of gravity) to prevent the L-shaped control rod from being unable to reset when released. When using a hard rope or rod, if the L-shaped control rod cannot be reset under the action of gravity, a hard chain can be used to push it counterclockwise to reset it.

[0009] Preferably, the angle of inclination of the right-angled trapezoidal box slope is 115°-125°. The angle of inclination of the box slope is set to 115°-125°, which is convenient for dumping materials and ensures that the material receiving box can receive more materials, thereby improving the efficiency of receiving and pouring materials.

[0015] Preferably, the rotating mechanism also includes two connecting blocks, the connecting blocks are connected to the bottom of the box body, the rotating shaft is arranged between the two connecting blocks and the two ends are respectively connected to the opposite sides of the two connecting blocks; the bearing assembly includes a bearing seat and a bearing arranged on the bearing seat, and the inner ring of the bearing is sleeved on the rotating shaft; the two bearing seats are both arranged at the first end of the transverse bracket.

[0016] Preferably, the rotating shaft is connected to the first end of the transverse bracket; the bearing assembly includes a bearing seat and a bearing arranged on the bearing seat, and the inner ring of the bearing is sleeved on the rotating shaft; the two bearing seats are respectively connected to the bottom of the box body.

[0017] Preferably, the receiving box body is welded with 10 mm thick steel plates. More preferably, other components of the device except the chain are also made of steel. The specific steel model can be selected and adjusted according to actual needs, and the present utility model does not impose too many restrictions.

[0018] Beneficial effects of the utility model:

[0019] (1) The utility model adopts a box body which is wide at the top and narrow at the bottom and has a right-angled trapezoidal cross section to replace the dustpan-shaped material receiving box in the prior art, thereby improving the sealing performance of the material receiving box, effectively preventing the material from leaking out from the side when receiving the material, increasing the material capacity of the material receiving box, and being able to receive more material each time, thereby improving the efficiency of receiving and pouring the material.

[0020] (2) The device of the present invention is provided with an automatic flipping mechanism, and the distance between the rotating connection and the second end of the bottom of the box body is less than half the length of the bottom of the box body, so as to ensure that the center of gravity of the material receiving box body is on the side close to the inclined surface of the box body, so as to ensure that the box body can be automatically flipped around the side of the inclined surface of the rotating mechanism.

[0021] (3) The device described in the present invention is provided with a hook and interlock system, which realizes the hook and interlock of the material receiving box through a fixed block, a "T"-shaped hook rod, an intermediate connecting rod, a control rod and a chain. The rotational connection between the "T"-shaped hook rod, the intermediate connecting rod and the control rod can be achieved by an articulated seat, a pin, or other methods, and the present invention does not impose too many restrictions. The fixed block is used for fixing, while the T-shaped hook rod, the middle connecting rod, and the control rod are used for transmission. When the chain pulls the vertical control rod, the control rod rotates clockwise around the endpoint of the transverse control rod. At this time, the connection between the vertical control rod and the transverse control rod is displaced upward. The vertical control rod pulls the T-shaped hook rod to rotate clockwise around the endpoint of the long side of the T-shaped hook rod. At this time, the lower end of the short side of the T-shaped hook rod is displaced upward, causing the lower end of the short side of the T-shaped hook rod to leave the box. The inside of the test box has no obstruction and tends to flip in the direction of the center of gravity. Therefore, the box flips around the rotating mechanism to the side with the inclined surface. In this way, the material receiving box can be automatically flipped. When the box needs to be reset, just gradually lower the entire device until the lowest point of the box touches the bottom surface, and then continue to lower the entire device. The box can rotate clockwise around the rotating mechanism until the second end of the bottom of the box returns to the upper end of the horizontal support frame. Then loosen the chain to reset the control rod, the middle connecting rod, and the "T"-shaped hook rod. At this time, the lower end of the short side of the "T"-shaped hook rod returns to the box and presses against the side of the box to prevent it from rotating, and the reset is completed.

[0028] The automatic flipping mechanism includes a bracket and a rotation mechanism, the bracket includes a horizontal bracket 2 and a longitudinal bracket 3, the horizontal bracket 2 includes a first end and a second end, so that the second end of the bottom of the box is arranged above the horizontal bracket 2 and the first end of the horizontal bracket 2 is rotatably connected to the bottom of the box through the rotation mechanism, the rotation angle of the rotation mechanism is preferably 0-180° in the counterclockwise direction (that is, the box can be flipped outward at most 180°, which can be more convenient to reset), so that the inclined surface of the box faces outward and the vertical surface opposite to the inclined surface is arranged in the direction of the longitudinal bracket 3, and the distance between the rotation connection and the second end of the bottom of the box is less than The second end of the horizontal bracket 2 is connected to the bottom end of the longitudinal bracket 3, and the end of the second end of the horizontal bracket 2 is further provided with a forklift socket, which is used to be sleeved outside the forklift spline to achieve connection with the forklift. Therefore, the size and shape of the forklift socket must correspond to the forklift spline to ensure that the spline can be inserted without too much gap, so as to ensure the stability of the connection. Generally speaking, the size of the forklift socket can be slightly larger than the size of the spline.

[0029] Reference Attachment Figure 2 The hook chain system includes a fixed block 5, a "T"-shaped hook rod 6, a control rod and a chain 7, and the fixed block 5 is connected to the top of the longitudinal bracket 3; the long side of the "T"-shaped hook rod 6 is horizontal and the short side is vertically arranged, the end of the long side of the "T"-shaped hook rod 6 is rotatably connected to the fixed block 5, and the lower end of the short side extends into the box body and is in contact with the side surface of the box body at the second end of the bottom of the box body; the control rod includes a vertical control rod 8 and a horizontal control rod 9, one end of the horizontal control rod 9 is fixedly connected to the bottom end of the vertical control rod 8, and the other end is rotatably connected to the fixed block 5, and the horizontal control rod 9 can be set horizontally or tilted laterally, and can be designed according to actual needs; the bottom end of the vertical control rod 8 is also rotatably connected to the upper end of the short side of the "T"-shaped hook rod 6 ( Figure 2 The structure given in the figure is a direct connection, but it can also be an indirect connection. Figure 3The embodiment shown is an indirect connection embodiment; one end of the chain 7 is connected to the vertical control rod 8; the material receiving box is interlocked by the fixed block 5, the T-shaped hook rod 6, the control rod, and the chain 7. The rotational connection between the T-shaped hook rod 6 and the control rod can be achieved by a hinged seat, a pin, or other methods, and the present invention does not impose any additional restrictions. The fixed block 5 is used for fixing, while the T-shaped hook rod 6 and the control rod are used for transmission. When the chain 7 pulls the vertical control rod 8, the control rod rotates clockwise around the end point of the transverse control rod 9. At this time, the connection between the vertical control rod 8 and the transverse control rod 9 is displaced upward. By pulling the T-shaped hook rod 6 through the vertical control rod 8, it rotates clockwise around the end point of the long side of the T-shaped hook rod 6. At this time, the lower end of the short side of the T-shaped hook rod 6 is displaced upward, causing the lower end of the short side of the T-shaped hook rod 6 to leave the box. The inside of the test box lacks obstruction and tends to flip in the direction of the center of gravity. Therefore, the box flips around the rotating mechanism to the side where the inclined surface is located. In this way, the material receiving box can be automatically flipped. When the box needs to be reset, it is only necessary to gradually lower the entire device until the lowest point of the box is against the bottom surface, and then continue to lower the entire device. The box can rotate clockwise around the rotating mechanism until the second end of the bottom of the box returns to the upper end of the horizontal support frame, and then loosen the chain 7 to reset the control rod and the "T"-shaped hook rod 6. At this time, the lower end of the short side of the "T"-shaped hook rod 6 returns to the box and presses against the side of the box to prevent it from rotating, and the reset is completed.

[0030] In some embodiments of the present invention, Figure 3The hook chain system includes a fixed block 5, a "T"-shaped hook rod 6, an intermediate connecting rod 11, an "L"-shaped control rod 10 and a chain 7, wherein the fixed block 5 is connected to the top end of the longitudinal bracket 3; the long side of the "T"-shaped hook rod 6 is horizontal and the short side is vertically arranged, the end of the long side of the "T"-shaped hook rod 6 is rotatably connected to the fixed block 5, the lower end of the short side extends into the box body and contacts the side surface of the box body at the second end of the bottom of the box body, and the function of the lower end of the short side of the "T"-shaped hook rod 6 is to prevent the box body from automatically turning over; the lower end of the intermediate connecting rod 11 is rotatably connected to the upper end of the short side of the "T"-shaped hook rod 6; the right-angle end of the "L"-shaped control rod 10 is rotatably connected to the upper end of the intermediate connecting rod 11, the short side of the "L"-shaped control rod 10 is horizontally arranged and its end point is rotatably connected to the fixed block 5; one end of the chain 7 is connected to the long side of the "L"-shaped control rod 10. The rotational connection between the "T"-shaped hook rod 6, the intermediate connecting rod 11, and the "L"-shaped control rod 10 can be achieved through an articulated seat, a pin, or other methods, and the present invention does not impose too many restrictions. The function of the fixed block 5 is to fix, and the function of the "T"-shaped hook rod 6, the intermediate connecting rod 11, and the "L"-shaped control rod 10 is to transmit. When the chain 7 pulls the long side of the "L"-shaped control rod 10, the "L"-shaped control rod 10 rotates clockwise around the end point of the short side. At this time, its right-angled end produces an upward displacement. The intermediate connecting rod 11 pulls the "T"-shaped hook rod 6 to rotate clockwise around the end point of the long side of the "T"-shaped hook rod 6. At this time, the lower end of the short side of the "T"-shaped hook rod 6 produces an upward displacement, causing the lower end of the short side of the "T"-shaped hook rod 6 to leave the box. The inside of the test box lacks obstruction and tends to flip in the direction of the center of gravity. Therefore, the box flips around the rotating mechanism to the side where the inclined surface is located. In this way, the material receiving box can be automatically flipped. When the box needs to be reset, it is only necessary to gradually lower the entire device so that the lowest point of the box is against the bottom surface, and then continue to lower the entire device. The box can rotate clockwise around the rotating mechanism until the second end of the bottom of the box returns to the upper end of the horizontal support frame, and then release the chain 7 to reset the "L"-shaped control rod 10, the middle connecting rod 11, and the "T"-shaped hook rod 6. At this time, the lower end of the short side of the "T"-shaped hook rod 6 returns to the box and resists the side of the box to prevent it from rotating, thus completing the reset. The height control of the entire device can be controlled by a forklift. The chain 7 can be a soft rope, or a hard rope or rod, and can be selected as needed. When using a soft rope, the angle of pulling should not be too large (to ensure that the "L"-shaped control rod 10 can be reset under the action of gravity) to prevent the "L"-shaped control rod 10 from being reset when released. When a hard rope or rod is used, if the "L"-shaped control rod 10 cannot be reset under the action of gravity, it can be reset by pushing it counterclockwise with the help of a hard chain 7.

[0031] In some embodiments of the present invention, the angle of inclination of the right-angled trapezoidal box body slope is 115°-125°. Setting the angle of inclination of the box body slope to 115°-125° not only facilitates the dumping of materials, but also ensures that the receiving box can receive more materials, thereby improving the efficiency of receiving and dumping materials.

[0032] In some embodiments of the present invention, the transverse support 2 includes two hollow transverse support rods and a first connecting rod, and the two transverse support rods are arranged parallel to each other; the first connecting rod is arranged at the second end of the transverse support 2 and is respectively vertically connected to the side surfaces of the ends of the two transverse support rods; the other ends of the two transverse support rods are rotatably connected to the bottom of the box through a rotating mechanism.

[0033] In some embodiments of the present invention, the transverse support rod is formed by welding two channel steels relative to each other.

[0034] In some embodiments of the present invention, the longitudinal bracket 3 includes two longitudinal support rods and a second connecting rod, the bottom ends of the two longitudinal support rods are respectively connected to the upper surfaces of the ends of the two transverse support rods on the side where the first connecting rod is located; the two ends of the second connecting rod are respectively connected to the top ends of the two longitudinal support rods.

[0035] In some embodiments of the present invention, the fixing block 5 is vertically arranged at the midpoint of the second connecting rod.

[0036] In some embodiments of the present invention, the rotating mechanism includes a rotating shaft 4 and at least two sets of bearing assemblies.

[0037] In some embodiments of the present invention, the rotating mechanism also includes two connecting blocks, which are connected to the bottom of the box body, and the rotating shaft 4 is arranged between the two connecting blocks and the two ends are respectively connected to the opposite sides of the two connecting blocks; the bearing assembly includes a bearing seat and a bearing arranged on the bearing seat, and the inner ring of the bearing is sleeved on the rotating shaft 4; the two bearing seats are both arranged at the first end of the transverse bracket 2.

[0038] In some embodiments of the present invention, the rotating shaft 4 is connected to the first end of the transverse bracket 2; the bearing assembly includes a bearing seat and a bearing arranged on the bearing seat, and the inner ring of the bearing is sleeved on the rotating shaft 4; the two bearing seats are respectively connected to the bottom of the box.

[0039] In some embodiments of the present invention, the material receiving box body 1 is welded with 10 mm thick steel plates. More preferably, other components of the device except the chain 7 are also made of steel. The specific steel model can be selected and adjusted according to actual needs, and the present invention does not impose too many restrictions.

[0040] The present invention replaces the dustpan-shaped material receiving box in the prior art with a box that is wide at the top and narrow at the bottom and has a right-angled trapezoidal cross-section. This improves the sealing performance of the material receiving box and effectively prevents material from leaking out from the sides when receiving materials. This increases the material capacity of the material receiving box, allowing it to receive more materials each time and improving the efficiency of receiving and unloading materials. An automatic flipping mechanism is provided, and the distance between the rotating connection and the second end of the bottom of the box is less than half the length of the bottom of the box, so as to ensure that the center of gravity of the material receiving box body 1 is on the side close to the inclined surface of the box body. This ensures that the box body can automatically flip around the side of the inclined surface of the rotating mechanism.
