Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grain surface sealing, in particular to a clamp type grain surface sealing device. BACKGROUND

[0002] The current widely used grain surface sealing method in grain depot is to install U-shaped grooves on the wall surface around the grain depot, and to press the sealing film into the inner cavity of the U-shaped groove with a hose, so that the wall surface around the grain depot, the bottom of the grain depot and the film on the grain surface form a sealed full-enclosing structure. The existing patents "Device and method for sealing grain surface" (publication number CN116335371A) and "Quick adjustable device for sealing grain surface" (publication number CN220191529U) describe devices in which the relative motion of the extrusion structure and the hose is tangential motion, and in the interaction force between the two, the tangential force is larger. The hose is subjected to a larger shearing action, while the normal extrusion force is smaller, which can cause a larger wear to the hose, thereby affecting its service life. The patent "Simple film covering and sealing device for grain depot" (publication number CN210726061U) describes a simple clamping body structure that replaces the current commonly used sealing groove structure, but its air tightness completely depends on the parameter design of the elastic structure of the clamping body and the elastic performance of the clamping body material. On the scale of the perimeter of the warehouse, it is difficult for such an elastic structure to maintain stable and consistent deformation, so it is not easy to ensure the sealing performance, and the implementation of this patent requires replacing the sealing grooves that have been installed in the existing warehouse, which cannot utilize existing facilities and has a large implementation difficulty. In summary, the above three patents all have some shortcomings. Moreover, there are no products related to these patents on the market. In the actual operation of the grain depot, the process of pressing the hose and the film into the groove still requires the operator to manually pinch and use common tools such as rubber hammers and pliers for auxiliary operation. This method not only wastes time and effort and is low in efficiency, but also easily damages the film and can cause harm to the worker's hands, posing a certain safety hazard. SUMMARY

[0003] In view of the problems in the prior art, the present application provides a clamp type grain surface sealing device, the main structure of which includes a base and an extrusion component, and the base and the extrusion component are hinged; the base and the extrusion component cooperate to press the hose and the film into the U-shaped groove on the wall surface.

[0004] In one embodiment, the device as a whole has a clamp structure, one side of which is a clamp jaw and the other side is a handle; or the clamp jaw and the handle are located on the same side.

[0005] In one embodiment, the base is a shell with a fixed handle, which provides support for the extrusion component.

[0006] In one embodiment, the extrusion component includes a movable handle, a transmission connecting rod and a sliding block connected in sequence.

[0007] In one embodiment, the extrusion component comprises an upper slider, a rear slider, a front connecting rod, a rear connecting rod, a push rod, a movable handle and corresponding hinges; the movable handle is connected with the upper slider through the front connecting rod; the movable handle is connected with the push rod through the rear connecting rod; the upper slider and the rear slider extrude the hose from different directions respectively.

[0008] In one embodiment, a spring is arranged between the fixed handle and the movable handle.

[0009] In one embodiment, a spring is arranged between the rear slider and the base.

[0010] In one embodiment, the fixed handle is in the shape of a circular arc.

[0011] In one embodiment, the movable handle is in the shape of S.

[0012] In one embodiment, the contact surface of the rear slider and the push rod is in the shape of an inclined plane, an over curve surface and a vertical plane.

[0013] The above technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the utility model can be achieved. For example, the connecting rod slider mechanism used in the device can be replaced by a cam mechanism, and the compression spring can be replaced by a leaf spring.

[0023] The utility model will be further explained in connection with the drawings below.

[0024] The utility model provides a clamp type grain surface sealing device, as Figures 1-4 The main body structure is connected by hinge by base and extrusion component. The base is the casing with handle, provides support for the extrusion component, and clamps the operated object (wall U-shaped groove, hose and film); the extrusion component is composed of active handle, slider and transmission connecting rod, etc. parts, can press the hose and film into the wall U-shaped groove. As Figure 1 The device is in the form of a clamp, with the left half as the jaw and the right half as the handle. The fixed handle is located on the base, and the active handle rotates around the hinge under the action of external force. The hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. The structure of the hinge includes the following basic components: hinge leaves or hinge plates, which are the main part of the hinge, made of metal such as steel or stainless steel. They are connected together by a pin or rivet, allowing relative rotation between the two leaves. Pin or rivet, the pin or rivet is used to connect the hinge leaves together and provide the axis of rotation. These can be cylindrical, fixed or removable, depending on the type of hinge. Mounting components: hinges are usually equipped with mounting screws or other fasteners to fix the hinge in the desired position. Adjustment mechanism: some hinges have an adjustment mechanism that allows users to adjust the opening angle, tension or position. These adjustment mechanisms may include screws, knobs or spring-loaded mechanisms. Decorative cover or hinge cap: some hinge designs include a decorative cover or hinge cap to hide the mounting screws and provide a more aesthetic appearance. These are removable for maintenance and adjustment. Additional functional components: depending on the type and purpose of the hinge, there may also be other functional components, such as dampers (for slowing down the rotation speed), spring-loaded mechanisms (for automatic recovery), locking mechanisms (for locking a certain position), etc. There are many types of hinges, including but not limited to: ordinary hinge: used to connect two planes, allowing them to rotate relative to each other within a certain range. Spring hinge: built-in spring, can automatically recover to the closed position. Damping hinge: with damper, can slow down the rotation speed, reduce noise and impact. Hidden hinge: designed to hide the hinge leaves inside, providing a cleaner appearance.

[0025] The extrusion components are the main active components for completing the sealing operation, including the upper slide 6, the rear slide 7, the front connecting rod 5, the rear connecting rod 8, the push rod 9, the movable handle 1 and corresponding hinges. The upper slide 6 is hinged with the front connecting rod 5, and the front connecting rod 5 is hinged with the movable handle 1; the rear slide 7 is connected with the push rod 9 through a beveled surface sliding connection, the push rod 9 is hinged with the rear connecting rod 8, and the rear connecting rod 8 is hinged with the movable handle 1.

[0026] The spring at the handle is a compression spring 4, and the spring connecting the rear slide and the base is a tension spring 3. These springs play a role in resetting the extrusion components.

[0027] In an embodiment, the connecting rod and slide mechanism can be replaced by a cam mechanism. The connecting rod and slide in the connecting rod and slide mechanism are replaced by a cam and a follower in the cam mechanism. According to the layout and size of the cam mechanism, the overall mechanical structure is adjusted to ensure that the relative positions and cooperation between the components are correct, and the movement effect of the connecting rod and slide mechanism can be achieved.

[0028] In a specific embodiment, the compression spring 4 originally used to provide elastic recovery force and compression function can be flexibly replaced by other types of elastic elements or mechanisms. Specifically, in addition to traditional compression springs, designers can consider using leaf springs as an alternative. Leaf springs have high rigidity and stable elastic performance, which can effectively replace compression springs in many situations, especially in situations that require large carrying capacity and stable recovery force. In addition, another innovative alternative is to use a controllable telescopic mechanism. This mechanism can accurately control the length and force of telescopic extension through electric, pneumatic or hydraulic driving methods, thereby providing more flexible and controllable compression and recovery functions than traditional compression springs. This alternative is particularly suitable for situations that require precise adjustment and dynamic control, such as precision machinery, automation equipment and other fields. In summary, in an embodiment, the function of the compression spring 4 can be realized by alternative solutions such as leaf springs or controllable telescopic mechanisms according to specific needs and design considerations. The compression spring 4 can also be selected from gas springs, hydraulic springs, rubber springs or other mechanical springs.

[0029] The specific operation steps for sealing the grain surface with a film are as follows:

[0030] (1) As shown in Figure 2 , first, the jaw part is clamped on the wall surface U-shaped groove 12 and the film 10, and the hose 11 is placed in the notch at the jaw position of the base 2.

[0031] (2) Squeeze the movable handle 1 tightly. The compression spring 4 will be compressed, and the movable handle 1 will rotate counterclockwise around the hinge, causing the front connecting rod 5 and the rear connecting rod 8 to move in a plane, thereby causing the upper slider 6 and the push rod 9 to move downward. The contact surface between the rear slider 7 and the push rod 9 is an inclined plane, and it will move to the left under the push of the push rod 9. The tension spring 3 is stretched, and the rear slider 7 squeezes the hose 11, gradually flattening it. At this time, the upper slider 6 is a certain distance from the hose 11 and will not exert any force on the hose.

[0032] (3) Continue to squeeze the movable handle 1, and the push rod 9 continues to move downwards. The contact surface with the rear slider 7 becomes a vertical plane, and no longer exerts a horizontal pushing force on the rear slider 7. The rear slider 7 moves to its extreme position to the left and will remain in this position, keeping the hose 11 flattened to a fixed width. During this process, the upper slider 6 continues to move downwards and contacts the hose 11, forcing the hose 11 and the membrane 10 to be pressed into the groove of the U-shaped channel on the wall, completing the sealing operation.

[0033] (4) Release the handle, the compression spring 4 returns to its original shape and the movable handle 1 is reset. The tension spring 3 returns to its original shape and brings the rear slider 7 back to its original position. A complete sealing process is completed.

[0034] (5) Slide the device horizontally along the U-shaped groove on the wall to the next position, repeat the above steps (1) to (4), and continue the sealing operation until the grain surface is completely sealed.
