Description

  TECHNICAL FIELD The present invention relates to a powder conveyance path cleaning device that cleans dust particles that are accumulated in a conveyance path of a combine or a powder processing machine by air blasting.

  In conventional combine and powder processing machines, the accumulation of powder residue in the conveyance path that forms a complex structure allows mold and mice to enter, making the conveyance path unsanitary. There was a problem. In addition, when the varieties of the powder particles remaining and deposited are different from the powder particles to be conveyed, the residual powder particles accumulated in the powder particles to be conveyed later are mixed, so-called contamination (mixing of different varieties). ), The quality and the commercial value are lowered, and there is a problem that the discharge efficiency of the powder particles at the time of conveyance is reduced.

  In order to solve the above problems, a conveyance path cleaning apparatus using a blower has been proposed. For example, a “combine grain discharging device” (Patent Document 1) that prevents scattering of grains, facilitates discharge work, and improves work efficiency has been proposed and is a known technique. Specifically, a traveling device provided below the fuselage frame, a threshing device provided at an upper position on the left and right sides of the fuselage frame, a Glen tank provided at an upper position on the left and right sides of the fuselage frame, and the Glen tank A grain discharge device for discharging the grain in the inside, and the grain discharge device includes a middle part of a discharge cylinder member having a grain discharge port at a tip and conveying the grain by high-pressure air from a blower. A traveling device that is connected to the discharge part of the grain tank and is provided below the machine frame with a pressure reducing device for reducing the pressure of the air blower from a blower at a predetermined position of the discharge passage extending from the discharge part to the grain outlet. An apparatus, a threshing device provided at an upper position on the left and right sides of the fuselage frame, a grain tank provided at an upper position on the left and right sides of the fuselage frame, and a grain discharging device for discharging the grains in the grain tank The grain discharging device has A discharge passage that has a grain outlet at the end and connects the middle part of the discharge cylinder member that conveys the grain with high-pressure air from the blower to the outlet of the Glen tank, and reaches the grain outlet from the outlet This is a proposal in which a pressure reducing device for reducing the pressure of the air blower is provided at a predetermined position.

  However, the proposal of such a “combined grain discharging device” employs a means for discharging the grain by blowing with a blower from one end of the discharging channel, so that the grain can be discharged efficiently. However, it has not been a proposal that can solve the problem that grains are accumulated at corners of the discharge channel that is bent in a complicated manner and has a long path.

  Moreover, "combine" (patent document 2) which can discharge | emit a grain smoothly from a grain storage apparatus to a discharge cylinder is proposed, and it is a well-known technique. Specifically, a grain storage device that stores the grain, a blower device that conveys the grain stored in the grain storage device, and a bottom of the grain storage device are provided. , One end is connected to the blower, the other end is connected to the discharge cylinder side for discharging the grain, and the grain stored in the grain storage device is conveyed by the air blown from the blower An air transport cylinder, one end of which is connected to the grain transport cylinder side, the other end is disposed in the grain storage apparatus, and the air blown from the blower is transported to the grain storage apparatus The air conveyance cylinder is a proposal that can blow down the grains remaining in the grain storage device to the lower side in the grain storage device.

  However, such a “combine” proposal can be smoothly discharged from the grain storage device for storing the grain to the discharge cylinder, but is also complicatedly bent and has a corner of the discharge channel having a long path. -It was not a proposal that could solve the problem of kernels accumulating in the (ner) part.

  Furthermore, a “combine sorting device” (Patent Document 3) that can easily clean the conveyor collar is proposed and is a publicly known technique. Specifically, a first air passage for sorting is formed from the blower outlet of Karatsu toward the upper position of the first grain receiver, and air is sent from the Kara to the first grain receiver through the first air path. In the combine sorting apparatus which wind-selects the threshed grain and receives the first selected wind grain in the first grain receiver, Forming a second air passage that blows air toward the lower position of the koji, and using the wind blown from the tang to the first grain receiver through the second air channel, the powder grains in the first grain receiver This is a proposal for removing the residue.

  However, the proposal of such a “combine sorting device” is to wind-select the threshed grain by blowing through the first air passage from Karatsu to the first grain receiver, Is a proposal for a combine sorting device that can easily clean a conveyor ridge by receiving the most grain at a corner, and also has a corner of a discharge channel that is bent in a complicated manner and has a long path (corner). It was not a proposal that could solve the problem that grains would accumulate in the part).

  The present applicant has a problem that powder particles accumulate and remain inside the conveyance path in conventional complex combine and powder processing machines, as well as generation of mold and rat intrusion caused by powder particles remaining With the idea of whether these problems can be solved with a very simple structure while using the air blowing means, the residual powder particles that accumulate in the transport path of the combine and the powder processing machine The present invention has developed a powder conveyance path cleaning device for cleaning an object by scattering by blowing air, leading to the proposal of the “powder conveyance path cleaning device” in the present invention.
