Description

Technical Field

[0001] This utility model relates to the field of grain suction machine technology, specifically an adjustable grain suction structure for a grain suction machine. Background Technology

[0002] A grain suction machine is a mechanical device used for efficient grain transport. It uses a fan to generate negative pressure to suck bulk grain from the grain pile into a pipe. After impurities are filtered out by a separation device, the clean grain is transported to a grain warehouse, transport vehicle or processing equipment. It is suitable for rapid operation in farms, grain depots, docks and other similar settings.

[0003] Existing grain suction machines generally suffer from clogging problems, mainly due to design flaws and the complexity of the operating environment: traditional fixed suction nozzles are difficult to fit the undulating grain pile surface, resulting in insufficient local vacuum and reduced suction power. At the same time, the internal space is prone to particle blockage under high-speed suction. To address this, we propose an adjustable grain suction structure for grain suction machines.

[0006] A bonding component is fixedly connected to a folded fabric at the bottom of multiple suction heads. A herringbone frame is fixedly connected to the bottom of the folded fabric, and a cushioning element is provided on the outside of the herringbone frame.

[0007] The buffer includes a connecting block fixedly connected to the outside of the U-shaped frame. A rotating wheel is rotatably connected to the bottom of the connecting block. A buffer rod is fixedly connected to the top of the connecting block. A buffer frame is fixedly connected to the outside of the suction head. The top of the buffer rod extends into the buffer frame and is fixedly connected to a limit rod. The top of the limit rod extends through the buffer frame. A spring is sleeved on the limit rod.

[0008] In some embodiments, the evacuation device includes a fixed frame fixedly connected inside the suction head, a long rod fixedly connected to the top of the fixed frame, and a crossbar fixedly connected to the outside of the long rod.

[0009] In some embodiments, the evacuation components are configured in multiple groups, which are respectively disposed in multiple suction heads, and each suction head is provided with two buffer components on both sides.

[0010] In some embodiments, a drive assembly is provided on one side of the plurality of suction heads, and a first drive element is provided within the drive assembly.

[0012] In some embodiments, the second driving member includes a triangular frame rotatably connected to the other side of the rotating plate, one end of the triangular frame is fixedly connected to a second hydraulic rod, and the driving end of the second hydraulic rod is fixedly connected to a slider.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] An adjustable grain suction structure for a grain suction machine includes a suction head 1 (in the prior art), with a conveying pipe 2 fixedly connected to the top of the suction head 1. The conveying pipe 2 is foldable and bendable.

[0027] like Figure 2 As shown, the bonding component 3 is fixedly connected to the folded fabric 31 at the bottom of multiple suction heads 1. The folded fabric 31 is foldable, durable, and corrosion-resistant. A U-shaped frame 32 is fixedly connected to the bottom of the folded fabric 31, and a buffer 33 is provided on the outer side of the U-shaped frame 32.

[0028] like Figure 3 As shown, the buffer 33 includes a connecting block 331 fixedly connected to the outside of the U-shaped frame 32. A rotating wheel 332 is rotatably connected to the bottom of the connecting block 331. A buffer rod 333 is fixedly connected to the top of the connecting block 331. A buffer frame 334 is fixedly connected to the outside of the suction head 1. The top of the buffer rod 333 extends into the buffer frame 334 and is fixedly connected to a limiting rod 335. The top of the limiting rod 335 extends through the buffer frame 334. A spring 336 is sleeved on the limiting rod 335. An evacuation component 34 is provided inside the suction head 1. Wherein:

[0029] like Figure 4As shown, the evacuation component 34 includes a fixed frame 341 fixedly connected inside the suction head 1. A long rod 342 is fixedly connected to the top of the fixed frame 341, and a crossbar 343 is fixedly connected to the outside of the long rod 342. Continuous lifting and lowering will cause the U-shaped frame 32 to vibrate. At the same time as the lifting and vibrating, the evacuation component 34 fixedly connected inside the U-shaped frame 32 will also be lifted and vibrated. The evacuation component 34 is configured in multiple groups, which are respectively arranged in multiple suction heads 1. Two buffers 33 are provided on both sides of each suction head 1.

[0030] When the device moves on the grain surface during use, its buffer 33 will rise and fall with the undulation of the grain. That is, the rotating wheel 332 drives the buffer rod 333 to rise and fall within the buffer frame 334. The spring 336 outside the limiting rod 335 provides buffering. At the same time, it can drive the U-shaped frame 32 to fit against the grain surface. Meanwhile, the continuous rise and fall will cause the U-shaped frame 32 to vibrate. At the same time, the rise and fall vibration will cause the evacuation component 34 fixedly connected inside the U-shaped frame 32 to rise and fall and vibrate. That is, it drives multiple sets of long rods 342 and crossbars 343 to rise and fall and vibrate, stirring and dispersing the grain blocked in the suction head 1.

[0031] Example 2

[0032] Please see Figure 1 and Figure 5 This utility model provides a technical solution:

[0033] Unlike Embodiment 1, a drive assembly 4 is provided on one side of the plurality of suction heads 1, and a first drive element 41 is provided inside the drive assembly 4, wherein:

[0034] like Figure 5 As shown, the first driving component 41 includes a connecting plate 411 fixedly connected to one side of a plurality of suction heads 1. A sliding frame 412 is slidably sleeved on the outer side of the connecting plate 411. A rotating plate 413 is fixedly connected to the outer side of the sliding frame 412. A support plate 414 is fixedly connected to one side of the rotating plate 413. A plurality of first hydraulic rods 415 are fixedly connected to the bottom of the support plate 414. The driving ends of the plurality of first hydraulic rods 415 are all fixedly connected to the connecting plate 411.

[0035] like Figure 5 As shown, the first hydraulic rod 415 drives the connecting plate 411 to slide up and down in the sliding frame 412, that is, it drives the multiple suction heads 1 to move up and down as a whole. In this way, the multiple suction heads 1 can be further driven to lift and vibrate, and further disperse the grain.

[0036] like Figure 5 As shown, a second driving member 42 is provided on the other side of the rotating plate 413, wherein:

[0037] The second driving component 42 includes a triangular frame 421 rotatably connected to the other side of the rotating plate 413. One end of the triangular frame 421 is fixedly connected to a second hydraulic rod 422, and the driving end of the second hydraulic rod 422 is fixedly connected to a slider 423. The triangular frame 421, the second hydraulic rod 422 and the slider 423 are set as two sets.

[0038] like Figure 5 As shown, the second driving component 42 also includes a rotating rod 424 rotatably connected to the other side of the rotating plate 413. A rod body 425 is fixedly connected between the outer ends of the two rotating rods 424, and two sliders 423 are rotatably connected to the two ends of the rod body 425 respectively.

[0039] It should be noted that the triangular frame 421 is used to connect to an existing vehicle, thereby enabling the device to move.

[0040] In use, the first hydraulic rod 415 drives the connecting plate 411 to slide up and down within the sliding frame 412, thereby driving multiple suction heads 1 to move up and down as a whole. This further drives the multiple suction heads 1 to vibrate up and down, further dispersing the grain. The two second hydraulic rods 422 are activated, driving the rod body 425 and the rotating rod 424 to rotate, thereby driving the rotating plate 413 to rotate. This drives the multiple suction heads 1 to rotate as a whole, further adhering to the grain pile. In addition, the driving stroke and driving frequency of the first hydraulic rod 415 and the second hydraulic rod 422 are adjustable.
