Description

Technical Field

[0001] This utility model relates to the field of grain suction machine technology, and in particular to a grain suction machine with an offset suction tube. Background Technology

[0002] Grain suction machines mainly use pneumatic conveying to transport granular materials and are suitable for bulk conveying of various small granular materials such as grains and plastics.

[0003] Figure 1 , Figure 2 The diagram shows a conventional grain suction machine structure. The grain suction device 1 is fixed to the traveling device 2, and the grain suction pipe 3 is mounted on the traveling device 2 via a rotating base 4. The grain suction pipe 3 can rotate around the center of the rotating base 4. The rotating base 4 and the grain suction device 1 are arranged side-by-side on the traveling device 2, with the rotating base 4 located at the middle left side of the grain suction device 1. The grain suction device 1 has partial structures distributed on both the front and rear sides of the rotating base 4. Figure 2 As shown, since the suction device 1 is partially distributed on both the front and rear sides of the rotating base 4, when the suction pipe 3 rotates around the center of the rotating base 4, the structures on both sides of the suction device 1 interfere with the rotation path of the suction pipe 3. This limits the suction pipe 3 to rotating within a 180° range, meaning it can only suction grain within a 180° working surface. The limited suction range means that for grain outside the working surface, the walking device 2 must be adjusted first, followed by the suction pipe 3, which is cumbersome, time-consuming, and reduces suction efficiency. Furthermore, because the suction pipe 3's rotation range is limited to 180°, it always extends beyond the range of the suction device 1, regardless of the angle it rotates to. This requires significant space during movement or parking, making the entire suction machine bulky, inconvenient to move and store, and resulting in high storage costs. Utility Model Content

[0004] In response to the aforementioned shortcomings of existing grain suction machines, the applicant provides a grain suction machine with a reasonably structured, offset grain suction pipe. The grain suction pipe is offset to the outer corner of the grain suction device, which expands the rotation range of the grain suction pipe, increases the working area of ​​grain suction, and improves grain suction efficiency. When moving or parking in the warehouse, the grain suction pipe can be rotated back and hidden within the range of the grain suction device. The overall size of the grain suction machine is smaller, making it easier to move and store, and reducing storage costs.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A grain suction machine with an offset suction pipe, wherein the grain suction device and the suction pipe are mounted on a walking device, the suction pipe is connected to a rotating seat and can rotate around the center of the rotating seat, the suction pipe and the rotating seat are offset to the outside of the corner of the grain suction device, and the suction pipe can rotate around the center of the rotating seat within the spatial range of two adjacent sides of the grain suction device.

[0007] As a further improvement to the above technical solution:

[0008] There is a certain distance between the center of the rotating seat and the two adjacent sides of the grain suction device.

[0009] The distance between the center of the rotating seat and the two adjacent sides of the grain suction device is greater than or equal to the radius r of the grain suction pipe.

[0010] The rotation angle range of the suction pipe is greater than or equal to 270°.

[0011] The grain suction device is located near the rear of the walking device, while the grain suction pipe and rotating seat are located near the front of the walking device and offset to the outer side of the front corner of the grain suction device.

[0012] The grain suction device is located near the front of the walking device, while the grain suction pipe and rotating seat are located near the rear of the walking device and offset to the outer side of the rear corner of the grain suction device.

[0013] The suction pipe is mounted on the hopper via a rotating seat. The hopper is located on one side of the suction device, and the suction pipe is connected to the hopper.

[0014] The beneficial effects of this utility model are as follows:

[0015] The suction pipe and rotating seat of this invention are offset to the outer corner of the suction device. The suction pipe can rotate within a working area of ​​at least 270° to suction grain, increasing the working area. By adjusting the angle of the suction pipe, grain can be sucked from a larger area, making suction more convenient, faster, and less time-consuming, thus improving suction efficiency. When in walking or storage mode, the suction pipe can be rotated back to a position close to the side of the suction device. At this time, the suction pipe is folded back and hidden within the suction device's range, with only a small extension outside the range, greatly reducing the overall volume of the suction machine, lowering space requirements, facilitating more flexible movement, and making storage easier, thus reducing storage costs.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figures 3 to 5 As shown, the grain suction device 1 of this utility model is fixedly installed on the platform of the walking device 2. A hopper 5 is fixedly installed on the platform of the walking device 2 at the front side of the grain suction device 1. The grain suction pipe 3 is installed on the hopper 5 through the rotating seat 4. The grain suction pipe 3 can rotate around the center of the rotating seat 4. The grain suction pipe 3 is connected to the hopper 5. The grain sucked in from the grain suction pipe 3 is sent to the belt conveyor through the hopper 5.

[0024] The grain suction device 1 is located in the middle of the platform of the traveling device 2, near the rear side of the platform. The grain suction pipe 3 and the rotating seat 4 are located on the left front side of the grain suction device 1, near the front side of the platform of the traveling device 2. The center of the rotating seat 4 is a certain distance away from the left side 11 and the front side 12 of the grain suction device 1. The distance d1 between the center of the rotating seat 4 and the left side 11 is greater than or equal to the radius r of the grain suction pipe 3, and the distance d2 between the center of the rotating seat 4 and the front side 12 is greater than or equal to the radius r of the grain suction pipe 3, ensuring that the grain suction pipe 3 has sufficient rotation space.

[0025] like Figure 4 As shown, because the suction pipe 3 and the rotating seat 4 are offset to the outer corner of the suction device 1, the suction pipe 3 can rotate around the center of the rotating seat 4 within the spatial range of two adjacent sides (left side 11 and front side 12) of the suction device 1. The rotation angle range of the suction pipe 3 is greater than or equal to 270°, allowing it to rotate within a working surface range of at least 270° for suction, thus increasing the working surface range for suction. By adjusting the angle of the suction pipe 3, a larger area of ​​grain can be suctioned, making suction more convenient, faster, and less time-consuming, thereby improving the efficiency of suction. Figure 4 As shown, the grain suction pipe 3 and the rotating seat 4 are offset to the outer side of the corner of the grain suction device 1, as follows: Figure 5 As shown, when in walking mode or in storage mode, the suction pipe 3 can be rotated back to a position close to the front side 12 of the suction device 1. At this time, the suction pipe 3 is folded back and hidden within the range of the suction device 1. The size of the pipe extending outside the range of the suction device 1 is very small, which greatly reduces the overall volume of the suction machine, reduces the requirements for space volume, makes it easier to move flexibly, and makes it easier to store and store, thus reducing storage costs.

[0026] In this embodiment, the grain suction device 1 is located near the rear of the traveling device 2, while the grain suction pipe 3 and the rotating seat 4 are located near the front of the traveling device 2 and offset to the outer side of the front corner of the grain suction device 1. In other embodiments, the grain suction device 1 can also be arranged near the front of the traveling device 2, while the grain suction pipe 3 and the rotating seat 4 are arranged near the rear of the traveling device 2 and offset to the outer side of the rear corner of the grain suction device 1, as long as the grain suction pipe 3 can rotate within a working surface range of at least 270°.

[0027] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
