Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a mobile screw conveyor. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate, thus pushing materials to achieve the purpose of conveying. It can convey materials horizontally, inclined, or vertically, and has advantages such as simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and suitability for enclosed transport. However, some existing screw conveyors cannot be moved flexibly to adapt to different locations, nor can the material conveying height be adjusted as needed, thus limiting their application.

[0003] Patent document CN203419490U discloses a mobile screw conveyor, including a screw conveyor body and a mobile frame. The mobile frame includes wheels and a support frame. The support frame includes an inclined rod and a fixed rod. The inclined rod is fixedly connected to the screw conveyor body, and the fixed rod is welded to the inclined rod. The wheels are hinged to the inclined rod. The mobile frame is installed below the screw conveyor body. This mobile screw conveyor can feed materials to multiple devices that are not in a straight line, meeting the user's requirements for feeding and discharging multiple devices and facilitating movement. However, the discharge port height of this mobile screw conveyor is not easily adjustable, making it unsuitable for feeding devices of different heights.

[0004] Patent document CN205687069U discloses a mobile lifting screw conveyor. One side of its horizontal support frame is fixed to the connecting shaft in the middle of the moving wheel, and the other side of the horizontal support frame is fixed to the steering wheel. The vertical support frame is fixed to the connecting shaft, and the middle of the vertical support frame is connected to the horizontal support frame through a diagonal brace. A manual winch is provided at the lower part of the vertical support frame, and a steel wire rope is wound on the steel wire rope roller of the manual winch. A fixed pulley is provided at the top of the vertical support frame, and a movable pulley is provided on the side of the screw conveyor near the discharge port. The steel wire rope passes through the fixed pulley and the movable pulley in sequence and is fixedly connected to the top of the vertical support frame. The screw conveyor is provided with a drive device for driving the screw conveyor. One end of the screw conveyor near the feed port is fixed to the horizontal support frame by a U-shaped clamp, and the U-shaped clamp is hinged to the horizontal support frame. The manual lifting device is powered by a manual winch. One end of the wire rope is fixed to the wire rope roller of the winch, and then passes through a fixed pulley and a movable pulley in sequence, connecting to the top of the vertical support frame. The principle of the fixed and movable pulleys is used to reduce traction. The length of the wire rope is controlled by the rotation of the wire rope roller of the winch, thus achieving the purpose of lifting the screw conveyor. However, this mobile lifting screw conveyor, by using a vertical support frame to support the fixed pulleys, has a large overall height, making it prone to height limitations during movement.

[0005] Patent document CN213084498U discloses a screw conveyor for feed production, including a base plate, a screw conveyor housing, and a height adjustment mechanism. The screw conveyor housing is a circular tube structure and is located at the upper end of the height adjustment mechanism. A feeding shaft is installed inside the screw conveyor housing, and several screw blades are evenly arranged on the feeding shaft. A motor is fixedly installed at the end of the screw conveyor housing, and the output end of the motor is fixedly connected to the feeding shaft. The height adjustment mechanism includes a triangular bracket located at the end of the screw conveyor housing near the motor and hinged to the screw conveyor housing. The triangular bracket is fixedly installed on the base plate. The upper end of the height adjustment mechanism is hinged to the screw conveyor housing, and the lower end is hinged to a moving column. The screw conveyor's tilt angle is adjusted by changing the fulcrum position of the second connecting rod on the base plate. However, the base plate is relatively long, and during feeding, it is easily obstructed by the storage device, resulting in the discharge port at the upper end of the screw conveyor not aligning vertically with the inlet of the storage device. Utility Model Content

[0006] The main purpose of this utility model is to provide a mobile screw conveyor that is easy to move, allows for easy adjustment of the discharge port height, and has a large range of movement for the discharge port.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A mobile screw conveyor includes an inclined screw conveyor body, the discharge port of which is higher than the inlet. A bracket is hinged to the lower end of the upper side of the screw conveyor body, and a guide wheel is rotatably connected to the lower end of the bracket. A lower ear plate is fixed to the lower end of the lower side of the screw conveyor body, and a support plate is rotatably connected to the lower ear plate. The support plate is fixed to the lower plate, and a caster is installed at the lower end of the lower plate. The lower end of the caster is flush with the lower end of the guide wheel. A rotating rod is fixed to the lower ear plate and is movably connected to the support plate via a first telescopic rod. The lower end of the bracket is inclined towards the lower plate, and a limit component is slidably provided on the lower plate, the limit component pressing against the lower part of the bracket. A top rod is fixed to the lower end of the screw conveyor body, and a vertical second telescopic rod is fixed to the upper end of the lower plate below the top rod. A top plate is fixed to the upper end of the second telescopic rod, and the upper end of the top plate pressing against the lower end of the top rod.

[0009] Specifically, the bracket includes two symmetrically arranged support rods. The upper ends of the two support rods are hinged to the upper ear plate fixed on the screw conveyor body. The middle of the two support rods is fixedly connected by a longitudinal intermediate rod. The lower ends of the two support rods are fixedly connected by a longitudinal lower rod. Guide wheels are rotatably connected to both ends of the lower rod. The intermediate rod and the lower rod are fixedly connected by a connecting rod, which is perpendicular to the lower rod.

[0010] Specifically, the limiting component includes a horizontally arranged push rod that is slidably connected to a lower plate. A locking handle is threadedly connected to the lower plate and presses against the push rod. A fork plate is fixed to the end of the push rod away from the lower plate, and a connecting rod is located inside the fork plate, with the fork plate pressing against the connecting rod.

[0011] Specifically, a pusher is fixed to the upper end of the lower plate.

[0012] Specifically, one end of the first telescopic rod is rotatably connected to the rotating rod, and the other end of the first telescopic rod is rotatably connected to the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The lower end of the bracket of this utility model is inclined towards the downward plate. The bracket is blocked by the limiting component. By setting the bracket, the support strength of the upper part of the screw conveyor body can be improved, thus improving the stability of this utility model.

[0016] 2. The lower end of the bracket is inclined towards the downward plate, which can increase the range of motion of the discharge port of the screw conveyor body. When loading materials into the car, the position adjustment range of the discharge port of the screw conveyor body is large, which can evenly load materials into the car and reduce the amount of manual work of transferring materials in the car.

[0017] 3. When conveying materials, the stability of the device can be improved by the support of the top plate on the top rod and the support of the bracket on the screw conveyor body, while reducing the pressure on the first telescopic rod, thus effectively protecting the first telescopic rod.

[0018] 4. By setting a counterweight, the weight of the screw conveyor body on the left side of the lower ear plate can be balanced. When the first telescopic rod is activated to adjust the angle of the screw conveyor body, the working pressure of the first telescopic rod is small, which can improve the service life of the first telescopic rod.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-3 As shown, a mobile screw conveyor includes an inclined screw conveyor body 1, wherein the height of the discharge port of the screw conveyor body 1 is greater than the height of the inlet of the screw conveyor body 1.

[0025] The lower end of the upper side of the screw conveyor body 1 is hinged to a bracket, and the lower end of the bracket is rotatably connected to a guide wheel 22.

[0026] The bracket includes two symmetrically arranged support rods 3, with the upper ends of the two support rods 3 hinged to the upper ear plate 2 fixed on the screw conveyor body 1. Specifically, the upper ends of the two support rods 3 are hinged to the upper ear plate 2 via upper rods 23. The middle of the two support rods 3 is fixedly connected by a longitudinal intermediate rod 4, and the lower ends of the two support rods 3 are fixedly connected by a longitudinal lower rod 5. Guide wheels 22 are rotatably connected to both ends of the lower rod 5. The intermediate rod 4 and the lower rod 5 are fixedly connected by a connecting rod 6, which is perpendicular to the lower rod 5.

[0027] A lower ear plate 10 is fixed to the lower end of the screw conveyor body 1. A support plate 11 is rotatably connected to the lower ear plate 10 and fixed to the lower plate 9. A rotating rod 12 is fixed to the lower ear plate 10, and the rotating rod 12 is movably connected to the support plate 11 through a first telescopic rod 13. Specifically, one end of the first telescopic rod 13 is rotatably connected to the rotating rod 12, and the other end of the first telescopic rod 13 is rotatably connected to the support plate 11.

[0028] A limit component is slidably mounted on the lower plate 9, and the limit component is tightly pressed against the lower side of the bracket. The lower end of the bracket is inclined towards the lower plate 9.

[0029] The limiting component includes a horizontally arranged push rod 7, which is slidably connected to the lower plate 9. A locking handle 24 is threadedly connected to the lower plate 9, and the locking handle 24 presses against the push rod 7. A fork plate 8 is fixed to the end of the push rod 7 away from the lower plate 9, and a connecting rod 6 is located inside the fork plate 8, with the fork plate 8 pressing against the connecting rod 6.

[0030] A top rod 17 is fixed at the lower end of the screw conveyor body 1. A vertical second telescopic rod 18 is fixed at the upper end of the lower plate 9 below the top rod 17. A top plate 19 is fixed at the upper end of the second telescopic rod 18. The upper end of the top plate 19 is tightly pressed against the lower end of the top rod 17.

[0031] A caster wheel 21 is installed at the lower end of the lower plate 9, and the lower end of the caster wheel 21 is flush with the lower end of the guide wheel 22.

[0032] A pusher 20 is fixed to the upper end of the lower plate 9.

[0033] When adjusting the tilt angle of the screw conveyor body 1, the first telescopic rod 13 is activated. After the length of the first telescopic rod 13 increases, the discharge port height of the screw conveyor body 1 increases; conversely, the discharge port height of the screw conveyor body 1 decreases.

[0034] During the process of the tilt angle of the screw conveyor body 1 changing, the guide wheel 22 is always in contact with the ground, and the angle between the bracket and the screw conveyor body 1 changes with the tilt angle of the screw conveyor body 1.

[0035] After the height of the discharge port of the screw conveyor body 1 is adjusted, the second telescopic rod 18 is started. The second telescopic rod 18 causes the top plate 19 to move upward, and after the top plate 19 moves upward, it presses against the top rod 17.

[0036] Then, the push rod 7 moves to the outside of the lower plate 9 until the fork plate 8 presses against the connecting rod 6. Then, the locking handle 24 is turned to position the connecting rod 6. At this time, the lower end of the bracket cannot rotate to the lower plate 9, and the bracket supports the upper part of the screw conveyor body 1.

[0037] Because the lower end of the bracket is inclined towards the downward plate 9, the bracket is blocked by the limiting component. By setting the bracket, the support strength and stability of the upper part of the screw conveyor body 1 can be improved.

[0038] The lower end of the bracket is inclined towards the lower plate 9, which can increase the range of motion of the discharge port of the screw conveyor body 1. When loading materials into the carriage, the position adjustment range of the discharge port of the screw conveyor body 1 is large, which can evenly load materials into the carriage and reduce the amount of manual work required to transfer materials in the carriage.

[0039] When conveying materials, the stability of the device can be improved by the support of the top plate 19 on the top rod 17 and the support of the bracket on the screw conveyor body 1, while reducing the pressure on the first telescopic rod 13, thereby effectively protecting the first telescopic rod 13.

[0040] Example 2: Based on Example 1, referring to the figure, the lower end of the screw conveyor body 1 between the top rod 17 and the lower ear plate 10 is fixed with a hanging ear 14, a hanging ring 15 is suspended on the hanging ear 14, and a counterweight 16 is fixed at the lower end of the hanging ring 15.

[0041] By setting a counterweight 16, the weight of the screw conveyor body 1 on the left side of the lower ear plate 10 can be balanced. When the first telescopic rod 13 is activated to adjust the angle of the screw conveyor body 1, the working pressure of the first telescopic rod 13 is small, which can improve the service life of the first telescopic rod 13.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
