Description

Technical Field

[0001] The utility model relates to the field of grain storage, in particular to a grain suction vehicle which is convenient for adjusting a grain suction pipeline and a shallow round silo using the grain suction vehicle. Background Art

[0002] The grain suction truck is a new type of agricultural and industrial machinery. It conveys granular materials pneumatically and is suitable for bulk conveying operations of various small granular materials such as grain and plastic. The pipeline layout can convey materials horizontally, inclined, and vertically. The pneumatic grain suction truck is suitable for loading and unloading, replenishing, unloading, turning over, and stacking in farms, docks, stations, and large grain depots, as well as mechanized operations of bulk, bulk transportation, and bulk unloading in the production process of grain processing, feed processing, and beer brewing industries. It can effectively save manpower and improve work efficiency. However, when using existing equipment, the connection angle of the suction pipe on the equipment is fixed, and the angle and length cannot be adjusted, which affects its scope of use and effect.

[0003] The prior art CN202123066829.6 discloses a grain suction vehicle that is convenient for multi-angle operation, including: a machine body, including a support frame, the surface of the support frame is fixedly connected to a grain suction component, and the surface of the grain suction component is connected to a grain suction pipe; an adjustment mechanism, including a support rod, the support rod is rotatably connected to the surface of the support frame, the end of the support rod away from the support frame is fixedly connected to a support plate, the surface of the support rod is sleeved with a connecting tube, and the outer surface of the connecting tube is movably connected to a telescopic push rod. Although this utility model solves the problem of angle adjustment under the action of the screw and the screw sleeve, the following problems still exist:

[0004] 1. Most of the existing grain suction vehicles use telescopic hoses as grain suction pipes. When the grain suction vehicle is running, the hoses are prone to shaking, resulting in poor grain suction effects and affecting efficiency.

[0005] 2. If a hard pipe is used as a grain suction pipe, the length of the pipe needs to be increased in real time according to the height of the grain when the grain is extracted. A pipe needs to be added at the end of the grain suction pipe to change the length of the grain suction pipe. Therefore, the grain suction pipe needs to be taken out and then a pipe needs to be added at the end. This solution is cumbersome to operate and affects production efficiency. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a grain suction vehicle that is easy to adjust the grain suction pipeline and a shallow circular silo using the grain suction vehicle. By adopting the cooperation of an adjusting device and a rotating support component, the number of vertical material pipe sections at the upper end of the vertical main material pipe of the grain suction pipeline can be quickly increased or decreased, thereby changing the length of the vertical main material pipe to facilitate the absorption of grain at different heights and improve work efficiency.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] Provided is a grain suction vehicle that facilitates the adjustment of a grain suction pipeline, comprising: a mobile chassis, a vacuum pump, a dust removal device, a slewing support component, a grain suction pipeline, and an adjustment device, wherein the dust removal device is arranged on the mobile chassis, the vacuum pump is arranged at the discharge end of the dust removal device, and the grain suction pipeline is connected to the dust removal device;

[0009] The grain suction pipeline includes a beam arm and a vertical main material pipe. One end of the beam arm is arranged on the dust removal device through a rotating support component, and the other end is connected to the vertical main material pipe. The vertical main material pipe is composed of multiple vertical material pipes connected by flanges. The adjustment device is sleeved on the outside of the vertical main material pipe and can clamp the vertical main material pipe. The adjustment device can increase or decrease the number of vertical material pipe sections at the upper end of the vertical main material pipe by cooperating with the rotating support component and the beam arm.

[0010] It should be noted that this scheme uses an adjusting device to fix the upper part of the vertical main material pipe. If it is necessary to add vertical material pipes, the clamping position of the adjusting device is close to the flange at the uppermost end of the vertical main material pipe, the flange at the connection with the beam arm is disassembled, and then the beam arm is raised, and the required vertical material pipe is fixed to the upper end of the vertical main material pipe through the flange and connected and fixed to the beam arm; conversely, if it is necessary to reduce the vertical material pipe, the clamping position is located at the flange below the vertical material pipe that needs to be reduced. After disassembly, the beam arm is pressed down and connected and fixed to the vertical main material pipe through the flange.

[0011] Preferably, the adjusting device is a hoisting mechanism, one end of which is fixed on the beam arm, and the other end of which is sleeved on the outer circumference of the vertical main material pipe and can clamp the vertical main material pipe.

[0012] It should be noted that the adjustment capability of the hoisting mechanism can be used to raise and lower the vertical main material pipe when increasing or decreasing the number of the pipes without the need for the pitching of the beam arm. Specifically, after the hoisting mechanism clamps the vertical main material pipe, the beam arm and the vertical main material pipe are separated by disassembling the flange directly connecting the vertical main material pipe and the beam arm, and then the hoisting mechanism is used to lift or lower the clamped vertical main material pipe portion, thereby adjusting the distance between the vertical material pipe and the beam arm at the clamping position to facilitate the increase or decrease of the vertical material pipes. At the same time, the distance between the beam arm and the vertical main material pipe can also be adjusted by pitching the beam arm, thereby increasing the adjustment range, so that multiple vertical material pipes can be increased or decreased at one time, thereby improving work efficiency.

[0013] Preferably, the adjusting device is a support seat, which is fixedly arranged on the warehouse body and includes a base and a push rod. A through hole is provided in the middle of the base, and the push rod is arranged at intervals on the circumference of the base and can tighten and fix the vertical main material pipe passing through the base.

[0014] It should be noted that by setting the support seat at the position where the vertical main material pipe extends into the warehouse body, a base is set up to allow the vertical main material pipe to pass through, and then the vertical main material pipe is fixed by a push rod.

[0015] Preferably, the vertical main material pipe is connected to the beam arm through a ball joint.

[0016] It should be noted that the use of a ball joint can reduce the difficulty of connecting and fixing the vertical main material pipe and the beam arm (reducing the difficulty of matching the connecting flange), thereby improving work efficiency.

[0017] Preferably, a suction nozzle is provided at the lower end of the vertical main material pipe.

[0018] It should be noted that the suction nozzle can fit the surface of the material more closely to improve the suction efficiency.

[0019] Preferably, the vacuum pump is provided with a muffler.

[0020] It should be noted that the muffler can reduce the noise during the operation of the vacuum pump and improve the comfort of the working environment.

[0021] A shallow round silo, comprising: a grain suction vehicle as described in any one of the above, an upper silo, a lower silo, and a plank road;

[0022] The lower end of the upper warehouse is connected to the upper end of the lower warehouse, and the upper warehouse and the lower warehouse are respectively located on the upper and lower sides of the ground, and a feed port is provided at the top of the upper warehouse; a plank road for the operation of the grain suction vehicle is provided in the radial direction of the upper end of the lower warehouse, and warehouse doors are respectively provided at both ends of the plank road, and the warehouse doors are located at the lower end of the upper warehouse.

[0023] Preferably, the plank road is made of grid plates.

[0024] It should be noted that by using a plank road made of grating plates, the grain falling from the top of the upper warehouse can pass through the grids of the grating plates into the lower warehouse, preventing it from piling up on the plank road and affecting the storage of the lower warehouse.

[0025] Preferably, the lower bin is a cone-bottom bin, and a through hole for a grain suction pipe to pass through is correspondingly provided at the center of the plank road above the center of the cone-bottom bin.

[0026] It should be noted that, by adopting a cone-bottom silo, the grain in the lower silo can be concentrated toward the center, and all the grain in the lower silo can be sucked without adjusting the position of the grain suction pipe, thereby improving work efficiency.

[0027] Beneficial effects of the utility model:

[0028] The utility model provides a grain suction vehicle that is convenient for adjusting the grain suction pipeline. By adopting the cooperation of the adjusting device and the slewing support component, the number of vertical material pipe sections at the upper end of the vertical main material pipe of the grain suction pipeline can be quickly increased or decreased, thereby changing the length of the vertical main material pipe, so as to absorb grains of different heights and improve work efficiency.

[0029] A shallow circular silo is also provided for the convenience of the grain suction vehicle to use. The height of the silo body above the ground is lowered, thereby reducing the power required for the conveyor and increasing the conveying efficiency. A plank road is provided in the shallow circular silo so that the grain suction vehicle can enter the silo body to extract grain from the lower silo. The plank road can also facilitate the staff to clean the inside of the silo body. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example 1

[0041] like Figure 1 As shown, a grain suction vehicle that is convenient for adjusting a grain suction pipeline 5 comprises: a mobile chassis 1, a vacuum pump 3, a dust removal device 2, a rotary support component 4, a grain suction pipeline 5, and an adjustment device 6. The dust removal device 2 is arranged on the mobile chassis 1, the vacuum pump 3 is arranged at the discharge end of the dust removal device 2, and the grain suction pipeline 5 is connected to the dust removal device 2;

[0042] The grain suction pipe 5 includes a beam arm 53 and a vertical main material pipe 52. One end of the beam arm 53 is set on the dust removal device 2 through the rotating support component 4, and the other end is connected to the vertical main material pipe 52. The vertical main material pipe 52 is composed of multiple vertical material pipes 521 connected by flanges. The adjusting device 6 is sleeved on the outside of the vertical main material pipe 52 and can clamp the vertical main material pipe 52. The adjusting device 6 can increase or decrease the number of sections of the vertical material pipe 521 at the upper end of the vertical main material pipe 52 by cooperating with the beam arm 53.

[0043] The regulating device 6 is a hoisting mechanism 61 , one end of which is fixed on the beam arm 53 , and the other end of which is sleeved on the outer circumference of the vertical main material pipe 52 and can clamp the vertical main material pipe 52 .

[0044] The vertical main material pipe 52 is connected to the beam arm 53 through a ball joint 51 .

[0045] A suction nozzle 8 is provided at the lower end of the vertical main material pipe 52 .

[0046] The vacuum pump 3 is provided with a muffler 7 .

[0047] The working principle and use method of a grain suction vehicle that facilitates adjustment of the grain suction pipeline 5 of this embodiment:

[0048] The present embodiment provides a grain suction vehicle which is convenient for adjusting the grain suction pipeline 5. After clamping the vertical main material pipe 52 by the hoisting mechanism 61, the beam arm 53 and the vertical main material pipe 52 are separated by disassembling the direct connection flange between the vertical main material pipe 52 and the beam arm 53. Then, the hoisting mechanism 61 is used to fix the separated part of the vertical material pipe 521, and the distance between the beam arm 53 and the vertical main material pipe 52 is adjusted by pitching the beam arm 53, or the clamped vertical main material pipe 52 is lifted or lowered by the hoisting mechanism 61, thereby adjusting the distance between the clamping part and the beam arm 53, so as to facilitate the increase or decrease of the vertical material pipe 521. The ball joint 51 is also used to reduce the difficulty of connecting and fixing the vertical main material pipe 52 and the beam arm 53, thereby improving work efficiency.

[0049] When in use, the grain suction vehicle is moved to the grain bin as a whole by moving the chassis 1, and the vertical main material pipe 52 is extended into the grain bin for suction. When the grain height is lowered and the grain cannot be sucked, the operator adjusts the pitch of the beam arm 53 to press the grain suction pipe 5 downward as a whole until it cannot be sucked again. The operator controls the hoisting mechanism 61 to clamp the upper end of the vertical main material pipe 52, disassembles the connecting flange between the beam arm 53 and the vertical main material pipe 52, and then controls the hoisting mechanism 61 and the beam arm 53 to operate so that the distance between the vertical main material pipe 52 and the beam arm 53 is sufficient to install the vertical material pipe 521, and then Then install the vertical material pipe 521 and fix it, and then continue to absorb grain until the grain in the granary is absorbed. Similarly, when the vertical pipeline needs to be disassembled, first drive the grain absorption pipeline 5 to rise as a whole through the beam arm 53, and control the operation of the hoisting mechanism 61 to clamp it under the vertical material pipe 521 that needs to be disassembled, and then press the beam arm 53 downward to lower the height of the vertical material pipe 521, so as to facilitate the disassembly of the flange connecting the beam arm 53 and the vertical main material pipe 52, and then use the hoisting mechanism 61 to gradually rise the vertical main material pipe 52, and disassemble the vertical material pipes 521 at different heights respectively.

Therefore, the silo doors 12 and plank road 11 are not only convenient for the transportation of grain, but also convenient for the staff to clean the inside of the silo body; the plank road 11 made of grating plates prevents grain from piling up on the plank road 11.

[0057] When in use, the staff opens the warehouse door 12 and uses the grain suction vehicle to pump the grain flowing out of the upper warehouse 9 from the warehouse door 12 to the transport vehicle until the grain storage height is lower than the height of the plank road 11, and then drives the grain suction vehicle into the warehouse through the plank road 11, so that the vertical main material pipe 52 of the grain suction vehicle extends into the lower warehouse 10 for suction. When it is necessary to adjust the length of the vertical main material pipe 52 of the grain suction vehicle, the vertical main material pipe 52 adjustment method used in Example 1 can be used to achieve it.

The adjusting device 6 can increase or decrease the number of sections of the vertical material pipe 521 at the upper end of the vertical main material pipe 52 by cooperating with the beam arm 53.

[0061] The adjusting device 6 is a support seat 62, which is fixedly arranged on the warehouse body, and the support seat 62 includes a base and a push rod 622. A through hole 13 is provided in the middle of the base. The push rod 622 is arranged at intervals on the circumference of the base and can tighten and fix the vertical main material pipe 52 passing through the base 621.

[0073] A shallow circular silo provided in this embodiment is divided into an existing shallow circular silo located on the ground as a whole into two parts, an upper and a lower part, so that the lower part is arranged under the ground, thereby reducing the height of the silo body above the ground, thereby reducing the power required by the conveyor, reducing energy consumption, reducing the transportation distance and increasing the transportation efficiency. In addition, a plank road 11 is arranged at the upper end of the lower silo 10, and silo doors 12 are arranged at the lower ends of the upper silo 9 at both ends of the plank road 11, so that a grain suction vehicle can enter the silo body to work, thereby facilitating the transportation of grain in the lower silo 10; the plank road 11 made of a grid plate is used to prevent grain from piling up on the plank road 11, and the grain suction pipeline 5 is fixedly supported by support seats 62 arranged at intervals on both sides of the plank road 11, thereby ensuring the stable operation of the grain suction pipeline 5.

[0074] When in use, the staff opens the warehouse door 12, and uses the grain suction vehicle to pump the grain in the upper warehouse 9 to the transport vehicle from the warehouse door 12 until the grain storage height is lower than the height of the plank road 11, and then extends the grain suction pipe 5 of the grain suction vehicle through the base 621 of the support seat 62 into the lower warehouse 10, and then tightens and fixes the grain suction pipe 5 through the push rod 622.
