Description

Technical Field

[0001] The utility model belongs to the field of transporting bulk materials and bulk material shaped lumps on a production line, and specifically relates to a semi-open hopper transport vehicle for transporting bulk materials or bulk material shaped lumps in batches on a production line, with automatic unloading and accurate feeding. Background Art

[0002] In most production lines in China, bulk materials or bulk material lumps are generally transferred in batches between different equipment and processes. The bulk material lumps are in certain regular shapes. Since the carriers used for materials transported in batches have certain carrying capacity limitations each time, for the purpose of convenient use, most production line transport carriers use hoppers to load and unload materials. When the hopper unloads, the bulk materials and bulk material lumps are automatically fed by their own weight. This is suitable for most container equipment with feeding ports facing upwards. This is also a common process equipment setting method used for automatic feeding of equipment to be fed on production lines.

[0003] The common ways of unloading materials in the feeding hopper of the transport vehicle used in the equipment with the feeding port facing upward in the existing production line are: the bottom structure adopts a flap-type opening door unloading method, or uses a spiral push structure to push the bulk material out of the discharge port to implement unloading, or adopts the overall dumping type of the hopper to unload. Among them, in the unloading method of the flap-type opening door, the downward-opening unloading flap will occupy the space below the hopper. When using it, it must be ensured that there is enough working space above the feeding port of the next process equipment or container, and it will also cause bulk material to pile up; the unloading method of the spiral push structure is prone to the relatively fixed position of the material during unloading, resulting in the accumulation of bulk materials, making the internal space utilization rate of the equipment being fed relatively low; the overall dumping type unloading is prone to overflowing from the equipment because the feeding speed cannot be controlled, which also causes the bulk material to pile up. None of the above three methods can guarantee that the bulk materials transferred in batches will not pile up after feeding and will be quickly discharged into the equipment container, nor can they achieve large-scale, fast and smooth unloading of bulk material lumps.

[0004] In order to ensure the smooth operation of the production line, the automatic unloading of the hopper transport vehicle in the production line is also the feeding process of the next process. The quality achieved in this process is closely related to the shape and state of the unloaded materials during unloading. Bulk material blocks are usually compressed into blocks according to the approximate size of the hopper of the transport vehicle, but the shape and size of the compressed bulk material blocks may change slightly during transportation. Some of the compressed bulk material blocks are loose and deformed and expand. They cannot pass smoothly through the discharge port that matches the original block size of the bulk material blocks by using a flap-type door opening or a dumping method. This constitutes an obstacle to the unloading of fixed discharge port sizes. When unloading bulk materials, the unloading method can easily cause irregular stacking of bulk materials in the container of the receiving equipment, and the upper surface of the pile is uneven, which wastes the storage space in the container of the receiving equipment and has an adverse effect on the subsequent process of the production line. Once these practical problems in on-site unloading occur, they must be manually adjusted or troubleshooted on-site, which not only wastes manpower and working hours, but also reduces the efficiency of the entire production line.

[0005] Aiming at the above-mentioned defects of bulk materials or bulk material lumps in batches being transported by hopper, automatic unloading, and unloading piling and obstruction of material dropping caused by feeding, the semi-open hopper transport vehicle used in the production line of the utility model can effectively solve these problems. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide a device that effectively solves the transportation, automatic unloading and feeding of bulk materials or bulk material shaped lumps in batches on the production line. It is a semi-open hopper transport vehicle for the production line with accurate cargo transportation, automatic unloading and feeding on the production line.

[0007] The utility model discloses a semi-open hopper conveyor for a production line, and its main structure comprises a body frame, a semi-open hopper movable enclosure, a movable bottom draw plate, a conveyor driving wheel, an electric push rod, a positioning frame, a reinforcing rib, a bottom draw plate frame, a bottom draw plate wheel rail, an electric motor, a hopper fixed enclosure, a bottom draw plate roller, a pin shaft, a bottom draw plate rack and pinion transmission, and a movable enclosure supporting wheel. A steel conveyor driving wheel is installed under the body frame, and the conveyor can travel on the material conveying wheel rail of the production line.

[0008] A fixed bottom draw plate wheel track is laid on the upper load-bearing panel of the vehicle body underframe, and the bottom draw plate wheel track extends forward from the rear end of the load-bearing panel above the vehicle body underframe to the bottom of the bottom draw plate frame, and the bottom draw plate frame is fixed to the front end of the load-bearing panel above the vehicle body underframe, and a hopper fixed enclosure is fixedly installed on the upper front part of the bottom draw plate frame, and the hopper fixed enclosure is respectively fixed to the bottom draw plate frame or the vehicle body underframe through reinforcing ribs of different sizes, and a positioning frame is fixedly installed on the upper rear end of the bottom draw plate frame, and the top end of the positioning frame is hinged to one end of an electric push rod, and the other end of the electric push rod is hinged to the middle part of the semi-opening hopper movable enclosure;

[0009] A movable enclosure support wheel is fixed to the lower part of the opening and closing end of the movable enclosure of the semi-opening hopper. When the fixed enclosure of the hopper and the movable enclosure of the semi-opening hopper are closed, they are cylindrical. When the movable bottom drawer completely enters the cylindrical bottom formed when the fixed enclosure of the hopper and the movable enclosure of the semi-opening hopper are closed, a barrel-shaped material storage space is formed, which can be used to carry the transported bulk materials or bulk material lumps.

[0010] The bottom drawer plate rollers are installed at the four corners below the movable bottom drawer plate, and the bottom drawer plate rollers can run on the bottom drawer plate wheel rails. A bottom drawer plate rack and pinion transmission is installed in the middle of the bottom of the movable bottom drawer plate. The rack in the bottom drawer plate rack and pinion transmission is fixed on the middle of the upper load-bearing panel of the vehicle body underframe, and the gear in the bottom drawer plate rack and pinion transmission is fixedly connected to the motor shaft.

[0011] When the motor drives the bottom draw plate rack and pinion transmission, the gear of the bottom draw plate rack and pinion transmission under the movable bottom draw plate moves on the rack, and the movable bottom draw plate connected to the gear shaft moves along with the gear, and at the same time, the bottom draw plate roller under the movable bottom draw plate moves along the bottom draw plate wheel track on the vehicle body underframe;

[0012] When the movable bottom drawer plate is pulled out, a cavity is formed at the bottom of the barrel-shaped storage space formed by the movable enclosure plate of the semi-open hopper and the fixed enclosure plate of the hopper, and the bulk materials or bulk material lumps in the barrel-shaped storage space can fall from the cavity at the bottom;

[0013] When transporting bulk materials, the speed of the movable bottom drawer plate being pulled out can be accurately controlled by the bottom drawer plate rack and pinion transmission, so as to adjust the size of the bottom cavity and the material dropping rate, control the flatness of the upper surface of the pile after the bulk materials are dropped, and complete the unloading quality control work;

[0014] When transporting bulk material lumps, the electric push rod hinged on the positioning frame is opened to push the movable enclosure of the semi-open hopper supported by the movable enclosure support wheel to move toward the fixed enclosure of the hopper. The movable enclosure of the semi-open hopper presses the bulk material lumps to cause them to deform slightly. At this time, the movable enclosure of the semi-open hopper and the fixed enclosure of the hopper clamp the bulk material lumps to keep them in a pinched state, and the movable bottom drawer plate can be pulled away from the bottom of the barrel-shaped storage space formed by the movable enclosure of the semi-open hopper and the fixed enclosure of the hopper to open the bottom. At this time, the electric push rod contracts, driving the movable enclosure of the semi-open hopper and the fixed enclosure of the hopper to disengage the clamping of the bulk material lumps, and the slightly deformed bulk material lumps are no longer in close contact with the inner wall of the movable enclosure of the semi-open hopper, and the bulk material lumps will fall directly and smoothly into the feeding port to complete the unloading work.

[0015] The utility model production line uses a semi-opening and closing hopper transport vehicle, wherein one of the opening and closing modes of the semi-opening and closing hopper movable enclosure and the hopper fixed enclosure is a semi-detached mode, that is, a positioning frame and an electric push rod are used. At this time, the top end of the positioning frame is hinged to one end of the electric push rod, and the other end of the electric push rod is hinged to the middle of the opening and closing end of the semi-opening and closing hopper movable enclosure. A movable enclosure support wheel is fixed to the lower part of the opening and closing end of the semi-opening and closing hopper movable enclosure, and at the same time, the non-opening and closing end of the semi-opening and closing hopper movable enclosure forms a hinge-like structure with one end of the hopper fixed enclosure by using a pin shaft;

[0016] When the electric push rod is extended or retracted, the electric push rod drives the opening and closing end of the movable enclosure of the semi-opening hopper supported by the movable enclosure support wheel, and realizes the opening and closing between the opening and closing end of the movable enclosure of the semi-opening hopper and the fixed enclosure of the hopper with the pin shaft as the rotation axis.

[0017] The utility model production line uses a semi-opening and closing hopper transport vehicle, wherein the second opening and closing mode of the semi-opening and closing hopper movable enclosure and the hopper fixed enclosure is a fully detachable mode, that is, a mode of using two sets of positioning frames and electric push rods. At this time, a positioning frame is respectively installed on both sides of the semi-opening and closing hopper movable enclosure, and the top of each positioning frame is hinged to one end of the electric push rod, and the other end of the electric push rod is respectively hinged to the middle of the two ends of the semi-opening and closing hopper movable enclosure, and the bottoms of the two ends of the semi-opening and closing hopper movable enclosure are equipped with movable enclosure support wheels to reduce movement resistance;

[0018] When the electric push rod is extended or retracted, the electric push rod drives the two ends of the connected semi-open hopper movable enclosure to move and break away from the contact with the hopper fixed enclosure, thereby realizing the complete opening and closing of the semi-open hopper movable enclosure and the hopper fixed enclosure.

[0019] The utility model discloses a semi-opening and closing type hopper conveying vehicle for a production line. A movable enclosure plate supporting wheel for auxiliary movement is installed below the opening and closing end of the movable enclosure plate of the semi-opening and closing type hopper.

[0020] The utility model is a semi-open hopper transport vehicle for a production line, wherein the semi-open hopper movable enclosure can change the size of the inner diameter of the hopper, thereby reducing the friction force that hinders the falling of bulk material lumps, and can avoid and prevent the blockage of discharging, unloading and feeding. It is easy to troubleshoot, and is a design with a high fault tolerance probability, which can effectively solve the problem of material falling being hindered. The movable bottom draw plate moves back and forth along the bottom draw plate wheel rail under the action of the motor through the bottom draw plate rack and pinion transmission, which can ensure that the hopper carries the bulk material and its lumps and the bottom is accurately controlled during unloading, effectively completing the loading, transportation and unloading of the bulk material and its lumps on the production line, and can effectively control the unloading and stacking problems of batches of bulk material and its lumps, and ensure that the upper surface of the material pile is flat after unloading. It is an effective solution to save storage space in the container of the receiving equipment and improve work efficiency. The semi-detachable semi-opening and closing method of the movable hopper enclosure and the fixed hopper enclosure saves construction and manufacturing costs, is particularly suitable for use in production lines to transport bulk materials into lumps, and has a high unloading efficiency.

[0034] A fixed bottom drawer plate wheel track 9 is laid on the upper load-bearing panel of the vehicle body underframe 1, and the bottom drawer plate wheel track 9 extends forward from the rear end of the load-bearing panel above the vehicle body underframe 1 to the bottom of the bottom drawer plate frame 8. The bottom drawer plate frame 8 is fixed to the front end of the load-bearing panel above the vehicle body underframe 1, and a hopper fixed enclosure 11 is fixedly installed on the front upper part of the bottom drawer plate frame 8. The hopper fixed enclosure 11 is respectively fixed to the bottom drawer plate frame 8 or the vehicle body underframe 1 through reinforcing ribs 7 of different sizes. A positioning frame 6 is fixedly installed on the rear end upper part of the bottom drawer plate frame 8, and the top end of the positioning frame 6 is hinged to one end of the electric push rod 5, and the other end of the electric push rod 5 is hinged to the middle part of the semi-open and closed hopper movable enclosure 2; when the electric push rod 5 is extended and retracted, the electric push rod 5 drives the two ends of the connected semi-open and closed hopper movable enclosure 2 to move, and break away from the contact with the hopper fixed enclosure 11, so as to realize the complete opening and closing of the semi-open and closed hopper movable enclosure 2 and the hopper fixed enclosure 11.

[0035] like Figure 2 As shown, the semi-open hopper transport vehicle for the production line of the utility model is a three-dimensional view of the semi-open hopper movable panel in a closed state. One of the opening and closing modes of the semi-open hopper movable panel 2 and the hopper fixed panel 11 is a semi-detached mode, that is, a positioning frame 6 and an electric push rod 5 are used. At this time, the top end of the positioning frame 6 is hinged to one end of the electric push rod 5, and the other end of the electric push rod 5 is hinged to the middle of the opening and closing end of the semi-open hopper movable panel 2. A movable panel support wheel 16 is fixed to the lower part of the opening and closing end of the semi-open hopper movable panel 2. At the same time, the non-opening and closing end of the semi-open hopper movable panel 2 uses a pin shaft 14 to form a hinge-like structure with one end of the hopper fixed panel 11.

[0036] When the electric push rod 5 is extended or retracted, the electric push rod 5 drives the opening and closing end of the semi-open and closing hopper movable enclosure 2 supported by the movable enclosure support wheel 16, and realizes the opening and closing between the opening and closing end of the semi-open and closing hopper movable enclosure 2 and the hopper fixed enclosure 11 with the pin shaft 14 as the rotation axis.

[0037] like Figure 3 As shown, when the semi-open and closed hopper conveyor vehicle for the production line of the utility model adopts the semi-detached type, the semi-open and closed hopper movable enclosure is in an open state. A movable enclosure support wheel 16 is fixed to the lower part of the opening and closing end of the semi-open and closed hopper movable enclosure 2, and at the same time, the non-opening and closing end of the semi-open and closed hopper movable enclosure 2 forms a hinge-like structure with one end of the hopper fixed enclosure 11 by using the pin shaft 14. The electric push rod 5 drives the opening and closing end of the semi-open and closed hopper movable enclosure 2 supported by the movable enclosure support wheel 16, and realizes the opening and closing between the opening and closing end of the semi-open and closed hopper movable enclosure 2 and the hopper fixed enclosure 11 with the pin shaft 14 as the rotation axis.

[0038] like Figure 4As shown, when the semi-open and closed hopper transport vehicle for the production line of the utility model adopts the semi-detached type, the semi-open and closed hopper movable panel is in a top view in a closed state. The non-opening and closing end of the semi-open and closed hopper movable panel 2 forms a hinge-like structure with one end of the hopper fixed panel 11 by using the pin shaft 14, and the electric push rod 5 drives the opening and closing end of the semi-open and closed hopper movable panel 2 supported by the movable panel support wheel 16, and realizes the opening and closing between the opening and closing end of the semi-open and closed hopper movable panel 2 and the hopper fixed panel 11 with the pin shaft 14 as the rotation axis, so that it is convenient to complete the work of carrying bulk materials to form lumps.

[0039] like Figure 5 As shown, when the semi-open and close hopper conveyor vehicle for the production line of the utility model adopts the fully detachable type, a three-dimensional view of the conveyor vehicle driving wheel is installed under the vehicle body frame. Under the opening and closing end of the semi-open and close hopper movable enclosure 2, an auxiliary movable enclosure support wheel 16 is installed. Under the vehicle body frame 1 and the movable bottom drawer 3, there are independent motors 10 to provide power.

[0040] like Figure 6 As shown in the figure, when the semi-open hopper transport vehicle for the production line of the utility model adopts the fully disengaged type, the semi-open hopper movable panel is in the open state. When transporting bulk materials to form lumps, the electric push rod 5 hinged on the positioning frame 6 is opened to push the semi-open hopper movable panel 2 supported by the movable panel support wheel 16 to move toward the hopper fixed panel 11. The semi-open hopper movable panel 2 presses the bulk materials to form lumps, causing them to deform slightly. At this time, the semi-open hopper movable panel 2 and the hopper fixed panel 11 clamp the bulk materials to form lumps to keep them in a pinched state, and the movable bottom drawer 3 can be pulled out of the semi-open hopper. The bottom of the barrel-shaped storage space formed by the movable enclosure 2 of the open and close hopper and the fixed enclosure 11 of the hopper is opened. At this time, the electric push rod 5 contracts, driving the movable enclosure 2 of the semi-open and close hopper and the fixed enclosure 11 of the hopper to disengage the clamping of the bulk material formed lumps. The slightly deformed bulk material formed lumps are no longer in close contact with the inner wall of the movable enclosure 2 of the semi-open and close hopper, and the bulk material formed lumps will fall directly and smoothly into the feeding port to complete the unloading work.

[0041] like Figure 7 As shown, Figure 7A three-dimensional view of the semi-open hopper movable enclosure in a closed state when the semi-open hopper transport vehicle for the production line of the utility model adopts the fully disengaged type. The second opening and closing mode of the semi-open hopper movable enclosure 2 and the hopper fixed enclosure 11 is the fully disengaged type, that is, the mode of using two sets of positioning frames 6 and electric push rods 5. At this time, a positioning frame 6 is installed on each side of the semi-open hopper movable enclosure 2, and the top of each positioning frame 6 is hinged to one end of the electric push rod 5, and the other end of the electric push rod 5 is respectively hinged to the middle of the two ends of the semi-open hopper movable enclosure 2. The bottoms of the two ends of the semi-open hopper movable enclosure 2 are equipped with movable enclosure support wheels 16 to reduce movement resistance.

[0042] like Figure 8 As shown, Figure 8 It is a three-dimensional partial cross-sectional view of the semi-open hopper transport vehicle for the production line of the utility model when the movable bottom drawer completely enters the bottom of the semi-open hopper movable enclosure. The movable enclosure support wheel 16 is fixed to the lower part of the opening and closing end of the semi-open hopper movable enclosure 2. The hopper fixed enclosure 11 and the semi-open hopper movable enclosure 2 are cylindrical when closed. When the movable bottom drawer 3 completely enters the cylindrical bottom formed when the hopper fixed enclosure 11 and the semi-open hopper movable enclosure 2 are closed, a barrel-shaped storage space is formed, which can be used to carry the transported bulk materials or bulk material lumps.

[0043] like Fig. 9 As shown, Fig. 9 It is a three-dimensional partial cross-sectional view of the semi-open hopper transport vehicle for production line of the utility model when the movable bottom drawer completely leaves the bottom of the semi-open hopper movable enclosure. The four corners below the movable bottom drawer 3 are equipped with bottom drawer rollers 12, which can run on the bottom drawer wheel rails 9. The middle part below the movable bottom drawer 3 is equipped with a bottom drawer rack and pinion transmission 15, the rack in the bottom drawer rack and pinion transmission 15 is fixed on the middle part of the upper load-bearing panel of the vehicle body underframe 1, and the gear in the bottom drawer rack and pinion transmission 15 is fixedly connected to the shaft of the motor 10.

[0044] When the motor 10 drives the bottom drawer plate rack and pinion transmission 15, the gear of the bottom drawer plate rack and pinion transmission 15 below the movable bottom drawer plate 3 moves on the rack, and the movable bottom drawer plate 3 connected to the gear shaft is displaced along with the gear, and at the same time, the bottom drawer plate roller 12 below the movable bottom drawer plate 3 moves along the bottom drawer plate wheel track 9 on the vehicle body underframe 1.

[0045] When the movable bottom drawer plate 3 is pulled out, a cavity is formed at the bottom of the barrel-shaped storage space formed by the movable enclosure plate 2 of the semi-open hopper and the fixed enclosure plate 11 of the hopper, and the bulk material or bulk material formed lumps in the barrel-shaped storage space can fall from the bottom cavity. The speed at which the movable bottom drawer plate 3 is pulled out can be accurately controlled by the bottom drawer plate rack and pinion transmission 15, so as to adjust the size of the bottom cavity and the material dropping rate, and control the flatness of the upper surface of the material pile after the bulk material or its formed lumps are dropped to complete the unloading quality control work.

[0046] When transporting bulk materials to form lumps, the electric push rod 5 hinged on the positioning frame 6 is opened to push the semi-open hopper movable panel 2 supported by the movable panel support wheel 16 to move toward the hopper fixed panel 11. The semi-open hopper movable panel 2 presses the bulk materials to form lumps, causing them to deform slightly. At this time, the semi-open hopper movable panel 2 and the hopper fixed panel 11 clamp the bulk materials to form lumps to keep them in a pinched state, and the movable bottom drawer 3 can be withdrawn from the semi-open hopper. The bottom of the barrel-shaped storage space formed by the movable enclosure 2 of the open and close hopper and the fixed enclosure 11 of the hopper is opened. At this time, the electric push rod 5 contracts, driving the movable enclosure 2 of the semi-open and close hopper and the fixed enclosure 11 of the hopper to disengage the clamping of the bulk material formed lumps. The slightly deformed bulk material formed lumps are no longer in close contact with the inner wall of the movable enclosure 2 of the semi-open and close hopper, and the bulk material formed lumps will fall directly and smoothly into the feeding port to complete the unloading work.

[0047] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by those skilled in the art should all fall within the protection scope of the claims of the present invention.
