Description

Technical Field

[0001] The invention relates to a plate processing technology, in particular to a low-noise grain sucking machine. Background Art

[0002] After bulk grain is transported by container grain trucks, it needs to be unloaded. When unloading grain in conjunction with the rear unloading platform, a reverse grain suction machine is required. The grain suction machine consists of an electric motor, a frame, a hose, a shaftless spiral blade and a suction head. Its working principle is that the motor is fixed on the frame, the shaftless spiral blade is installed in the hose, and the front end is connected to the suction head. When the motor is started, the motor drives the shaftless spiral blade to rotate. Under the action of the shaftless spiral blade, the grain at the suction head will rise along the spiral rise angle direction of the shaftless spiral blade. When it reaches the discharge port, it is automatically unloaded due to the action of gravity.

[0003] In the Chinese invention patent with publication number CN116891126A, a suction head for a grain suction machine capable of automatically adjusting the grain suction position is disclosed. The suction head for a grain suction machine capable of automatically adjusting the grain suction position is extended to both sides by controlling the movable components on both sides of the mounting frame until the two movable components are respectively in contact with both sides of the top of the grain transport vehicle frame, and then the two movable components are erected on both sides of the top of the grain transport vehicle frame, and at the same time, the two movable components are connected to both sides of the top of the grain transport vehicle frame by rolling, and the hose is connected to the top of the suction component, and the suction component is controlled to move vertically to achieve It can automatically suck and process grains at different depths inside the grain truck. At the same time, the driving component inside the driving frame drives the suction component at the bottom to move horizontally at the bottom of the mounting frame, and cooperates with the movable components on both sides of the mounting frame to drive the mounting frame as a whole to move longitudinally on the top of the grain truck frame, thereby realizing flexible adjustment of the position of the suction component inside the grain truck, allowing the suction component to quickly suck and process the grain inside the grain truck. The entire grain sucking process does not require manual adjustment of the position of the suction component, which saves time and effort, and can also effectively improve the efficiency of unloading grain from the grain truck to the grain receiving bin.

[0004] The existing grain sucking machine will generate a lot of noise during operation, and a large part of the noise comes from the vibration of the grain sucking machine when it is working. The grain sucking machine will vibrate when working, thereby making noise.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example: See Figure 1-Figure 8 A low-noise grain sucker includes a base 1. A driving member 11 is arranged on the upper end of the base 1, and a noise reduction component 2 is arranged on the outer surface of the output end of the driving member 11. The noise reduction component 2 reduces the vibration transmission of the driving member 11, and a collecting cylinder 12 is arranged at the output end of the driving member 11.

[0037] In this solution, the driving member 11 is a device with power output such as a motor, and is connected to an external control device. When the driving member 11 is started, it can synchronously drive the spiral blades arranged at its output end to rotate, thereby providing suction for the entire device.

[0038] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

[0039] Furthermore, the protective component 3 is assembled in the inner cavity of the collecting cylinder 12, and is used to break up the grain that is sucked into the collecting cylinder 12 and agglomerated. The protective component 3 includes a cylinder 31 connected to the inner wall of the collecting cylinder 12, and the inner cavity of the cylinder 31 is provided with a power member 32, and the output end of the power member 32 is provided with a rotating gear 33, and the end of the rotating gear 33 is rotatably mounted with a fixed block 331, and the outer surface of the fixed block 331 is provided with a plurality of groups of positioning rods 36, and the plurality of groups of positioning rods 36 are evenly distributed on the outer surface of the fixed block 331.

[0040] In this embodiment, the power member 32 is a device with power output such as a motor, and is connected to an external control device. When the power member 32 is started, it synchronously drives the rotating gear 33 arranged at its output end to rotate.

[0041] At the same time, the upper end of the rotating gear 33 is connected to the clamping block through the fixing block 331 , wherein the clamping block is connected to the inner wall of the cylinder 31 , thereby further limiting the rotating gear 33 .

[0042] A plurality of support rods are arranged at the lower end of the cylinder 31 and are evenly distributed at the lower end of the cylinder 31. The ends of the support rods are connected to the inner wall of the input end of the collecting cylinder 12, thereby ensuring the stability of the entire protective assembly 3 without affecting the grain transportation.

[0043] Furthermore, an adjustment block 35 is slidably installed on the outer surface of the positioning rod 36, and a transmission rod 34 is rotatably installed on one end of the adjustment block 35 and located on one side of the positioning rod 36. One end of the transmission rod 34 passes through and extends to the outside of the adjustment block 35, and the outer surface of the end of the transmission rod 34 is meshed with the upper end of the rotating gear 33.

[0044] Specifically, the outer surface of the transmission rod 34 is provided with a thread. When the transmission rod 34 rotates, the adjustment block 35 is synchronously driven to move. Since the inner wall of the adjustment block 35 is slidingly connected with the outer surface of the positioning rod 36, when the adjustment block 35 moves, it is limited by the positioning rod 36 to prevent the adjustment block 35 from deviating from the set trajectory when moving.

[0045] Furthermore, a protective plate 37 is provided on the inner wall of the cylinder 31 and above the adjusting block 35, and an arc groove 371 corresponding to the adjusting block 35 is provided at the end of the protective plate 37, and a driving block 372 is slidably mounted on the inner wall of the arc groove 371, and the lower end of the driving block 372 is connected to the upper end of the adjusting block 35. A conical block 373 is provided at the upper end of the protective plate 37, and the cross section of the conical block 373 is smaller than the cross section of the input end of the collecting cylinder 12.

[0046] Specifically, when the adjustment block 35 moves, it cooperates with the driving block 372 to drive the protective plate 37 to rotate. Since a conical block 373 is provided at the upper end of the protective plate 37, the conical block 373 is rotated to prevent food from piling up on the conical block 373.

[0047] Furthermore, a push rod 38 is provided at the lower end of the outer surface of the driving block 372, and the end of the push rod 38 passes through and extends to the outside of the cylinder 31. At the same time, a connecting block 381 is provided at the end of the push rod 38, and an arc plate 39 is rotatably installed at one end of the connecting block 381 away from the push rod 38.

[0048] Specifically, when the driving block 372 moves, the push rod 38 arranged on its outer surface is synchronously driven to move. Since a connecting block 381 is provided at the end of the push rod 38, and an arc plate 39 is rotatably installed at the end of the connecting block 381, when the push rod 38 reciprocates, the arc plate 39 is driven to move toward the inner wall of the collecting cylinder 12 to break up the agglomerated grains, thereby avoiding the agglomeration of wet grains and increasing the risk of blockage.

[0049] Furthermore, the noise reduction component 2 includes a bottom plate 21 connected to the base 1, the bottom plate 21 has a C-shaped longitudinal section, and holes 22 are provided on both sides of the bottom plate 21, and a limit rod 23 is slidably installed on the inner wall of the hole 22. Both ends of the limit rod 23 are provided with a telescopic member 232, and the lower end of the telescopic member 232 is connected to one side of the bottom plate 21.

[0050] In this embodiment, the telescopic member 232 is an elastic member such as an elastic rod, which is used to support the limiting rod 23 so that the limiting rod 23 can transmit vibration when a force is applied.

[0051] Furthermore, a positioning block 231 is rotatably mounted on the outer surface of the limiting rod 23 , and the outer surface of the positioning block 231 is slidably connected to the inner wall of the bottom plate 21 .

[0052] Specifically, the limiting rod 23 is supported by the positioning block 231, and a groove is opened on the bottom of the positioning block 231, and a protrusion slides on the inner wall of the groove, wherein the protrusion is connected to the inner wall of the bottom plate 21, so as to provide a running track when the positioning block 231 moves.

[0053] Furthermore, a pressing block 24 is rotatably mounted on the outer surface of the limiting rod 23 and the middle position of the positioning block 231, and a slot 241 is opened on one side of the pressing block 24. A movable rod 25 is arranged on the inner wall of the bottom plate 21, and the outer surface of the movable rod 25 is slidably connected to the inner wall of the slot 241.

[0054] Specifically, the pressing block 24 is limited by the movable rod 25, so that when the pressing block 24 is subjected to force, the pressing block 24 rotates around the movable rod 25, and when the pressing block 24 moves downward, it simultaneously drives the limit rod 23 to move, and cooperates with the telescopic member 232 to buffer the limit rod 23.

[0055] Furthermore, an extension rod 26 is rotatably mounted on the outer surface of the pressing block 24, and a slide groove 27 is provided on the outer surface of the extension rod 26. An elastic member 272 is provided on the inner wall of the slide groove 27, and a slider 271 is provided on the end of the elastic member 272. The outer surface of the slider 271 is slidably connected to the inner wall of the slide groove 27.

[0056] Specifically, the elastic member 272 is an elastic member such as a spring, and the slider 271 is supported by the elastic member 272 , and the force applied to the slider 271 can be buffered at the same time.

[0057] Furthermore, a guide groove 274 is formed on one side of the extension rod 26 , and a support plate 273 is slidably mounted on the inner wall of the guide groove 274 , and an end of the support plate 273 is connected to the outer surface of the slider 271 .

[0058] Specifically, the outer surface of the support plate 273 is provided with anti-slip components such as rubber, wherein the cross section of the support plate 273 is arc-shaped, and the output end of the driving member 11 is supported by the support plate 273 to separate the vibration source from the supporting structure and reduce the impact of vibration.

[0059] When the driving member 11 is started, the rotating shaft at its output end is supported by the support plate 273, thereby isolating the vibration source from the supporting structure, so that the vibration generated when the driving member 11 is in use is transmitted to the elastic member 272 and the telescopic member 232 in sequence through the support plate 273, thereby reducing the noise generated when the driving member 11 is activated and improving the working environment.

[0060] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
