Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a feeding device that supplies grain to a grain conditioning machine or the like.

(Prior art) A grain supply hopper that receives released grains and supplies them to a regulator etc. needs to be temporarily stored in response to an increase or decrease in the number of released grains. In order to receive the liquid without scattering it, the hopper body is made larger than the intake port of the regulator, that is, the supply port of the hopper.

(Problem to be solved by the invention) As mentioned above, when supplying grain from the hopper to the grain conditioning machine, despite the capacity of the conditioning machine being large, due to the nature of the conditioning machine, the supply port of the hopper is too large. In such cases, it is necessary to efficiently feed grains through a small feeding port.

When observing the state of grain supply from the supply hopper of conventional equipment from this perspective, it is found that when the grains released from the chute collide with the bottom of the hopper, some of the grains spread to both sides. As the grains flow down and gather at the center of the hopper again near the supply port, these scattered grains collide with the grains flowing down the center of the hopper near the supply port, greatly disrupting the grain flow. It was discovered that the grain supply was significantly reduced. This invention attempts to solve such problems.

(Means for Solving the Problems) Grain in which a supply port 1 is opened at the lower front, a bottom plate 2 is tilted downward toward the supply port 1, and standing walls 3, 3 are erected around the bottom plate 2. In the supply hopper 4, two guide plates 5, 5 with a height lower than the vertical wall 3 are placed on the bottom plate 2 from both left and right ends of the supply port 1, facing rearward with a slight distance l from the supply port 1. A structure of a grain feeding device which is provided with a rectification guide passage 6 which is installed upright and guided toward the supply port 1 in the hopper 4, and recovery guide passages 7, 7 for collecting scattered grains on both sides of the guide passage 6. shall be.

(Operation of the device) When grains are fed with the direction of discharge from the chute directed toward the rectifying guide passage 6 at the center of the hopper 4 formed by the guide plates 5, 5, the discharged grains are Although it collides with the bottom plate 2 of the hopper 4, it is prevented from spreading to both sides by the guide plates 5, 5.
It flows down the particle size regulating guide passage 6 toward the supply port 1 while being subjected to a rectifying effect, without generating turbulence.
Further, the water is efficiently supplied to the regulator from the supply port 1 without reducing the flow rate. In addition, an extremely large amount of grain is supplied from the chute, and the grains and scattered grains that overflow the guide plates 5, 5 are transferred to the grading guide path 6.
The grains are collected in the collection guide passages 7, 7 on both sides, flow down, and flow into the supply port 1 from the gap 1 between the supply port 1 and the guide plates 5, 5 at a speed that does not disturb the flow of grains in the grading guide passage 6. .

(Effect of the invention) Since this invention is constructed as described above, the grains discharged from the chute to the hopper 4 are passed through the rectifying guide passage 6 formed by the guide plates 5, 5 to the hopper 4. Directly guide the flow to the supply port 1 while rectifying the flow without spreading it to both sides,
The grains can be efficiently supplied from the supply port 1 to the regulator without generating turbulence or reducing the flow velocity as in the past, and the grains can be prevented from overflowing from the guide plates 5, 5 to both sides and scattering. The grains can be collected by the collection guide passages 7, 7 and allowed to flow into the supply port 1 through the interval 1 between the supply port 1 and the guide plates 5, 5. Therefore, even if a large amount of grain is supplied to the hopper 4, it is smoothly supplied from the supply port 1 into the inside of the regulator.
