Description

Technical Field

[0001] The invention relates to the technical field of grain transport, and in particular to a grain suction machine. Background Art

[0002] A grain suction machine (pneumatic conveyor) is an agricultural and industrial machine that conveys granular materials pneumatically. It is suitable for bulk conveying of various small granular materials such as rice, wheat, and plastic. It can convey materials horizontally, obliquely, and vertically by using pipeline layout. It has large and small running wheels, is simple and convenient to operate, and can complete the conveying task independently. When using a traditional grain suction machine, first insert the conveying hose into the grain pile, and use the negative pressure generated by the grain suction fan to suck up the grain to achieve the grain transfer. Because the granular grain is fluid and the hose cannot penetrate deep into the grain pile, the grain pile is prone to quickly form pits at the insertion point of the hose during use. In order to avoid the end of the conveying hose being exposed to the air and reducing the grain suction efficiency, workers are usually required to continuously push the upper grain to the pit to cover the pit, which is time-consuming and labor-intensive. Summary of the invention

[0003] The object of the present invention is to provide a grain sucking machine which has the effect of enabling a conveying hose to penetrate deeply into a grain pile.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: a grain suction machine, characterized in that it includes a grain suction fan and a conveying hose connected to the feed port of the grain suction fan, a grain suction shovel is provided at one end of the conveying hose away from the grain suction fan, a push rod is rotatably connected to the grain suction shovel, and a limit ring is provided on the push rod for the conveying hose to be rotatably embedded.

[0005] By adopting the above technical solution, a grain suction shovel is arranged at the end of the conveying hose away from the grain suction fan, and a push rod is rotatably connected to the grain suction shovel. Before sucking grain, the push rod is rotated to embed the conveying hose into the limiting ring, and the grain suction shovel is pushed deep into the grain pile by pushing the push rod. When a pit appears in the grain pile, the push rod is rotated to disengage the conveying hose from the limiting ring, and the grain suction shovel is continuously pushed into the grain pile by the push rod to prevent the grain suction shovel from being exposed to the air and reducing the grain suction efficiency.

[0006] The present invention is further configured as follows: the limiting ring is configured as a major arc, and an anti-slip pad is provided inside the limiting ring.

[0007] The present invention is further configured as follows: a pushing handle is fixedly provided at one end of the pushing rod away from the grain suction shovel, and an anti-slip sleeve is sleeved on the pushing handle.

[0008] The present invention is further configured as follows: the side of the grain suction shovel away from the ground is configured to be inclined.

[0009] The present invention is further configured as follows: the side of the grain suction shovel close to the ground is configured as a plane and is rotatably connected to at least one roller.

[0010] The present invention is further configured as follows: a fastening piece and a limiting plate are provided on the grain suction fan, a limiting screw is threadedly connected to the limiting plate, and the limiting screw passes through the limiting plate toward the fastening piece.

[0011] The present invention is further configured as follows: an anti-sliding block is provided at one end of the fastening piece facing the limit screw.

[0012] The beneficial effects of the present invention are:

[0013] 1. Before grain transportation, the conveying hose is embedded in the limiting ring by rotating the push rod, so that the conveying hose is fixed on the push rod, and the grain suction shovel is inserted into the grain pile through the push rod, thereby increasing the insertion depth of the grain suction shovel into the grain pile; when pits gradually appear in the grain pile, the push rod is rotated to make the limiting ring separate from the conveying hose, and the grain suction shovel is pushed by the push rod to continue to slide into the grain pile, thereby improving the grain suction efficiency and making it more labor-saving to drive the grain suction shovel.

[0014] 2. Rotate the connecting roller at the bottom of the grain suction shovel to reduce the friction between the bottom of the grain suction shovel and the ground when pushing the grain suction shovel, making it easier to drive the grain suction shovel.

[0015] 3. A fastening plate and a limit plate are set on the grain suction fan. When the grain needs to be transported to the transfer vehicle, the side plate of the transfer vehicle is set between the fastening plate and the limit plate, and the limit screw is turned to tighten the side plate of the transfer vehicle, thereby fixing the grain suction fan on the transfer vehicle and improving the stability of the grain suction fan setting.

[0016] 4. Set the limit ring to be able to slide on the push rod to adjust the relative position to prevent the limit ring from repeatedly rubbing the conveying hose at the same position and causing excessive wear of the conveying hose. BRIEF DESCRIPTION OF THE DRAWINGS
