An apparatus and method for sealing grain surfaces

Abstract

This invention provides a device and method for sealing grain surfaces, mainly comprising a frame and functional components. The frame is U-shaped or Г-shaped, and this semi-enclosed structure allows the device to stably clamp onto the object being operated on (U-shaped groove, hose, and membrane). A U-shaped frame is used when the opening of the U-shaped groove on the wall faces upwards; a Г-shaped frame is used when the opening of the U-shaped groove on the wall is normal to the wall. The frame consists of guide wheels and a handle. For the U-shaped frame, the guide wheels include an adjustable front guide wheel and a fixed bottom guide wheel; for the Г-shaped frame, there is a fixed upper guide wheel. In use, the guide wheels move forward, continuously flattening the membrane, which reduces friction and lowers the risk of membrane damage.

Description

Technical Field

[0001] This invention relates to the field of grain surface sealing technology, and particularly to an apparatus and method for sealing grain surfaces. Background Technology

[0002] The most common method for sealing grain surfaces in grain depots involves installing U-shaped grooves on the grain silo walls and pressing a sealing film into the inner cavity of the grooves using a flexible tube. In practice, this process of pressing the tube and film into the grooves typically relies on manual squeezing by operators, aided by tools such as rubber mallets and pliers. This method is not only time-consuming and labor-intensive, but also extremely inefficient, easily damaging the film and posing a safety hazard to workers' hands. Summary of the Invention

[0003] To address the problems in the prior art, this application proposes a device for sealing grain surfaces, comprising a support component and a pressing component. The support component is connected to the pressing component and provides support for the pressing component. The pressing component is capable of pressing a hose and a diaphragm into a U-shaped groove in the wall surface.

[0004] Preferably, the supporting component is a U-shaped frame or a Γ-shaped frame, and the pressure tube component is located inside the U-shaped frame or Γ-shaped frame.

[0005] Preferably, the device for sealing the grain surface further includes a first guiding component, which is connected to a support component or a pressure pipe component, and is used to guide the device to move along the U-shaped groove of the wall.

[0006] Preferably, the pressing component is a roller structure, a planar structure, an inclined surface structure, or a curved surface structure.

[0007] Preferably, the device for sealing the grain surface further includes a second guide component, which forms a clamping structure to enable the pressing of the hose and the film.

[0008] Preferably, when the supporting component of the device for sealing the grain surface is a U-shaped frame structure, the device further includes a second guiding component. The second guiding component, together with the supporting component and the pressing component, constitutes a clamping mechanism to realize the function of pressing the hose and the film. The device for sealing the grain surface also includes a handle, which is connected to the supporting component and is used to push the device to move along the U-shaped groove of the wall. When using the device, a thrust along the U-shaped groove of the wall needs to be applied to the handle to push the device to move continuously along the U-shaped groove of the wall.

[0009] Preferably, the device for sealing the grain surface also includes a handle, which is connected to the support component and is used to push the device to move along the U-shaped groove of the wall. When the support component of the device for sealing the grain surface is a Г-shaped frame structure, a positive pressure perpendicular to the wall and a thrust along the U-shaped groove of the wall need to be applied to the handle at the same time. The positive pressure is used to press the hose and the membrane, and the thrust is used to push the device to move continuously along the U-shaped groove of the wall.

[0010] Preferably, the relative positions of the pressure tube component and the first guide component with the support component are adjustable, so that they can be adapted to wall U-shaped grooves of different sizes.

[0011] Preferably, the pressing component has a guide wheel inside, which cooperates with the first guide component and / or the second guide component to press the hose into the wall U-shaped groove while the guide hose extends along the wall U-shaped groove.

[0012] Preferably, the pressure tube component and the first guide component are located on opposite sides of the U-shaped frame.

[0013] Preferably, the hose pressing component has a guide wheel and a pressing wheel inside, and the pressure applied by the pressing wheel to the hose is greater than the pressure applied by the guide wheel to the hose.

[0014] Preferably, the front end of the hose clamping component has a guide port, which can adjust the posture of the hose as it enters the subsequent mechanism and prevent the hose from being squeezed, deformed, and deviating from the guide wheel behind it.

[0015] Preferably, when the supporting component of the device for sealing the grain surface is a U-shaped frame structure, by adjusting the position of the pressing tube component and the first guide component, the gap between the pressing tube component and the wall surface is made slightly larger than the thickness of the film, so that the film on the right side of the pressing tube component can move freely, avoiding the film from being deformed or damaged by tension during the pressing process.

[0016] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0017] The present invention provides an apparatus and method for sealing grain surfaces, which, compared with the prior art, has at least the following advantages: it enables automatic and rapid processing of grain surface sealing, is simple to operate, has high safety, and can greatly improve work efficiency.

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] This invention provides a device for sealing grain surfaces, such as... Figure 1 As shown, it includes a support component and a crimping component. The support component is connected to the crimping component and provides support for the crimping component; the crimping component is movable along the hose direction. The support component is also provided with a handle for gripping.

[0032] In one embodiment, the support component is a U-shaped frame, and the pressing component is located inside the U-shaped frame. To facilitate adjustment of the position of the pressing component, and thus the pressing depth or pressing pressure, the pressing component and the U-shaped frame are connected by an adjustable mechanism, such as a threaded mechanism, a telescopic rod, or a cam mechanism.

[0033] In one embodiment, the device for sealing the grain surface further includes a first guiding component connected to a support component or a pressing component, for guiding the pressing component to move along the hose direction. The first guiding component may be a guide wheel, a guide arc surface, or a guide ramp, etc. There may be multiple guiding components, and they may work together.

[0034] In one embodiment, the crimping component is a roller structure, a planar structure, an inclined surface structure, or a curved surface structure. There can be multiple crimping components, which can have different shapes, sizes, or heights. These multiple crimping components can work together to achieve efficient hose installation by applying forces of different magnitudes and directions to the hose.

[0035] In one embodiment, such as Figure 2 As shown, the supporting component is a Г-shaped frame, which can better adapt to irregularly shaped spaces.

[0036] In one embodiment, such as Figure 3 As shown, the device for sealing the grain surface also includes a second guiding component, which is used to keep the film flat. The second guiding component works in conjunction with the first guiding component to achieve a guiding effect. The second guiding component and the first guiding component are located on two sides of the U-shaped groove on the wall surface. These two sides can be opposite directions or perpendicular to each other. The coordinated guiding of the second guiding component and the first guiding component makes the pressing quality more stable and the sealing consistency better. The pressing method can be from above (e.g., pressing from above). Figure 3 As shown), it can also be pressed in from the front (as shown). Figure 4 As shown). Figure 3 As shown, when the crimping component simultaneously presses the hose and diaphragm into the U-shaped groove on the wall, one side of the diaphragm is free to move. The U-shaped structure is achieved by leaving a gap between the crimping component and the wall. Figure 4 As shown, the lower part of the Г shape is naturally open, allowing the lower membrane to move freely. This avoids damage caused by compression and deformation after the membrane is completely fixed.

[0037] In one embodiment, such as Figure 5As shown, the pressing component cooperates with the first guiding component to press the hose into the U-shaped groove of the wall while guiding the hose to extend along it. The pressing component includes a pressing wheel located in the middle of the first guiding component. It also includes two guiding wheels and two arc plates. The two guiding wheels are located on either side of the pressing wheel, and the two arc plates are located on the outer sides of the two guiding wheels. The upper edge of the two arc plates has a guide opening for the hose to pass through. The guide opening at the front end of the pressing component adjusts the posture of the hose as it enters the subsequent mechanism, preventing the hose from being squeezed and deformed, thus preventing it from deviating from the rear guiding wheels. The grooved wheel at the front of the pressing component is a guiding wheel, which pre-compresses the hose, changing it from a cylindrical shape to a flattened cylindrical shape, facilitating the multiple cylindrical wheels to fully press it into the U-shaped groove of the wall. The lower edge of the pressing wheel is slightly lower than the lower edges of the two guiding wheels.

[0038] In one embodiment, the crimping component includes multiple guide wheels, with arc-shaped limiting structures on both sides of the multiple guide wheels, and a connecting plate between the arc-shaped limiting structures, the connecting plate being used to support the guide wheels.

[0039] In one embodiment, the second guide component is located between the first guide component and the pressing component. The first guide component and the pressing component are used to guide the vertical direction of the wall U-shaped groove, and the second guide component is used to guide the horizontal direction of the wall U-shaped groove.

[0040] In one embodiment, the second guide component is located between the first guide component and the pressing component. The first guide component and the pressing component are used to guide the horizontal direction of the wall U-shaped groove, and the second guide component is used to guide the vertical direction of the wall U-shaped groove.

[0041] In one embodiment, the first guide member and the crimping member are located on the same side of the U-shaped groove in the wall, and the pressure applied by the crimping member to the hose is greater than the pressure applied by the first guide member to the hose.

[0042] In one embodiment, the first guide member is located on one, two, or more sides of the crimping member.

[0043] In one embodiment, such as Figure 6-8 As shown, the crimping roller and / or guide roller may have one or more grooves for crimping or guiding one or more hoses. The crimping roller and / or guide roller may have the same shape or be configured with different shapes. The crimping direction may be frontal or lateral.
