Description

Technical Field

[0001] This utility model belongs to the technical field of material loading and unloading devices, and specifically relates to a flow control device for unloading bulk material trucks. Background Technology

[0002] Bulk materials are typically transported by trucks. Unloading involves opening the truck doors, making it difficult to control the unloading flow. Taking grain transport as an example, grain trucks at storage facilities and flour mills require coordination with conveying or cleaning equipment during unloading. Therefore, controlling the grain flow is crucial. Currently, the truck doors are usually manually secured to control their opening, and then released after unloading. However, this operation requires workers to operate during the unloading process, increasing the risk of accidental injury. Furthermore, the dust generated during unloading poses a serious threat to the health of workers. Utility Model Content

[0003] To address the above problems, this utility model provides a flow control device for unloading bulk material trucks.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A flow control device for unloading bulk material trucks includes a base, a screw, and sliders. Two bases are provided, each fixed to the outside of two relatively openable truck doors. The screw has two ends connected to the two bases, and its middle section has oppositely oriented external threads on both sides. Two sliders are provided, each with oppositely oriented internal threads, symmetrically arranged on the screw and threadedly engaged with it. Each slider has a limiting claw for hooking onto a post on the outer edge of the truck door.

[0006] Furthermore, the limiting claw is L-shaped, with its short side fixedly connected to the slider, and its long side able to be inserted into the gap between the carriage door and the pillar.

[0007] Furthermore, one end of the screw is connected to an electric wrench, which is wirelessly connected to a remote control, which can remotely control the electric wrench to drive the screw.

[0008] Furthermore, the electric wrench includes a protective cover and a motor and a reducer inside it, the output end of the motor is connected to the reducer, and the output end of the reducer is connected to the end of the screw.

[0009] Furthermore, the electric wrench also includes a controller and a battery. The motor is connected to the controller, which can be wirelessly connected to a remote control. The battery is electrically connected to the motor, reducer, and controller to provide power. A relay within the controller acts as a switch to control the forward and reverse rotation of the motor, and the motor drives the screw to rotate remotely via the remote control.

[0010] Furthermore, the motor is a DC motor with a self-locking function.

[0011] Furthermore, both bases are magnetic bases, namely a first magnetic base and a second magnetic base. The first magnetic base is rotatably connected to one end of the screw via a connecting rod, and the second magnetic base is connected to the electric wrench via a bracket.

[0012] Furthermore, the controller and battery can be located on one side of the second magnetic base, and the cable connected to the motor can be located inside the bracket.

[0013] Furthermore, the end of the connecting rod is provided with a spherical crown-shaped connector, and the end of the screw is provided with a corresponding ball head that matches the connector.

[0014] Furthermore, it also includes a disassembly wrench for prying open the base.

[0015] The technological advancements achieved by this invention compared to existing technologies are as follows:

[0016] This invention involves fixing bases to the outside of two carriage doors, and laterally arranging screws with oppositely rotating threads on both sides between the screw carriage doors. Limiting claws on sliders hook onto the uprights at the free edge of the carriage doors. The distance between the two sliders and the limiting claws can be adjusted by remotely rotating the screws, thereby opening the two carriage doors and controlling their opening degree to control the material flow. After unloading, the bases are removed from the carriage doors. This invention features a simple and compact structure, convenient and quick operation, and achieves unloading flow control without on-site personnel, avoiding accidental injuries.

[0024] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a flow control device for unloading bulk material trucks includes a base 1, a screw 2, and sliders 3. Two bases 1 are provided, each fixed to the outside of two opening / closing truck doors 4. The screw 2 is connected to both bases 1 at both ends, and has oppositely oriented external threads on both sides of its middle section. Two sliders 3 are provided, each with oppositely oriented internal threads, symmetrically arranged on the screw 2 and threadedly engaged with it. Each slider 3 has limiting claws 5 for hooking onto the outer edges of the truck doors 4. In use, the base is fixed to the outside of the two truck doors, allowing the limiting claws to hook onto the outer edges. Rotating the screw increases the distance between the two limiting claws, thereby opening the two truck doors and controlling their opening degree, thus controlling the unloading flow rate. After unloading, the base is removed from the truck doors.

[0026] As a preferred structure, such as Figure 1 As shown, the limiting claw 5 is L-shaped. The short side of the limiting claw 5 is fixedly connected to the slider 3, and the long side of the limiting claw 5 can be inserted into the gap between the carriage door 4 and the column 6. In specific manufacturing, the limiting claw can be made by bending steel plate. In addition, in order to better cooperate with the column, a rotatable hook can be provided at the end of the long side of the limiting claw. The hook consists of two sections, both of which are rotatably connected by a rotating shaft with a torsion spring. When in use, after prying open the hook to let it pass through the gap between the carriage door and the column, releasing the hook will allow the limiting claw to grip the column tightly under the action of the torsion spring.

[0027] In specific embodiments of this utility model, such as Figure 1 , 2 As shown, one end of the screw 2 is connected to an electric wrench, which is wirelessly connected to a remote control. The remote control can remotely control the electric wrench to drive the screw 2. The electric wrench includes a protective cover 7 and its internal motor 8 and reducer 9, as well as a controller and battery (not shown in the figure). The output end of the motor 8 is connected to the reducer 9, and the output end of the reducer 9 is connected to the end of the screw 2. The battery is electrically connected to the motor, reducer, and controller, providing them with power. The motor is controlled by the controller, which can also wirelessly connect to the remote control. In practical manufacturing, a square plane can be machined at the end of the screw to facilitate insertion into the square shaft hole at the end of the reducer's output shaft. The two work in a relatively static fit to smoothly transmit torque.

[0028] In the specific design, the motor 8 is a DC motor with a self-locking function. The relay in the controller acts as a switch to realize the forward and reverse rotation of the DC motor. After inputting the operation command through the remote control button, the receiver in the controller receives the radio frequency modulation signal, controls the relay to act, and the DC motor runs, driving the screw to rotate through the reducer. The forward and reverse rotation of the screw realizes the distance adjustment of the two sliders, thereby controlling the opening and closing adjustment of the carriage door. No on-site operation by staff is required, which can keep the staff away from the pollution, dust and other harmful environments, which is beneficial to their physical and mental health.

[0029] In the specific production process, such as Figure 1 As shown, both bases 1 are magnetic bases, namely a first magnetic base 11 and a second magnetic base 12. The first magnetic base 11 is rotatably connected to one end of the screw 2 via a connecting rod 10, facilitating adjustment of the angle between the connecting rod and the screw. The second magnetic base 12 is rotatably connected to the protective cover 7 of the electric wrench via a bracket 13, facilitating adjustment of the angle between the bracket and the screw. The controller and battery can be located on one side of the second magnetic base 12, and the cable connected to the motor 8 is located inside the bracket 13. The magnetic bases are the same as the magnetic gauge bases, and will not be described further here. By rotating the switch to activate its strong magnetism, the first magnetic base 11 and the second magnetic base 12 can be firmly attached to the two side doors of the carriage; rotating the switch in the opposite direction demagnetizes them, allowing them to easily detach from the carriage doors.

[0030] In specific embodiments of this utility model, such as Figure 1As shown, the end of the connecting rod 10 is provided with a spherical connector 14, and the end of the screw 2 is provided with a corresponding ball head 15 that matches the connector 14. In actual manufacturing, the outlet diameter of the connector is smaller than the diameter of the ball head to ensure that the ball head will not detach from the connector during rotation. By rotating the switch on the first magnetic base, the first magnetic base can be made to have a strong magnetism and be attracted to the carriage door. The connecting rod, through the rotational engagement of the connector and the ball head, facilitates the adjustment of the angle between the connecting rod and the screw.

[0031] Further optimization of the above solution includes a disassembly wrench for prying off the base. An F-type wrench can be used; when using it to attach or detach the two magnetic bases from the carriage door, applying torque to the switch on the side of the base with the F-type wrench allows for easy rotation of the switch, making operation more convenient.

[0032] The specific application process is as follows: After attaching the two magnetic bases to the outer walls of the two carriage doors, the operator moves away from the carriage and remotely controls the motor to gradually increase the distance between the two sliders. The carriage doors gradually open under the action of the limit claws, allowing the material to flow out until the required flow rate is reached, at which point the motor stops. After the material is unloaded and the carriage leaves the unloading site, the motor is reversed using the remote control, the distance between the two sliders decreases, and the carriage doors gradually close under the action of the limit claws. Finally, the two magnetic bases can be removed from the carriage doors.

[0033] In summary, this utility model has the advantages of simple and compact structure and convenient and quick operation. Two magnetic bases are attached to two carriage doors, and two limiting claws hook onto the side columns, allowing personnel to evacuate the site. An electric wrench is remotely controlled via a remote control, which rotates a screw to adjust the distance between the two sliders and the limiting claws, opening the two carriage doors and controlling their opening degree to control the unloading flow rate. After unloading, the magnetic bases are removed from the carriage doors. This utility model allows for remote control adjustment of the carriage door opening, eliminating the need for on-site personnel and preventing accidental injuries. It also keeps personnel away from polluted, dusty, and other harmful environments, protecting their health. This utility model is suitable for flow control during the unloading process of some granular material transport vehicles or some fluid material transport vehicles, facilitating widespread application.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
