Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a feeding device that can be used in any grain processing equipment other than a rice mill.

(Prior art) The conventionally known Japanese Utility Model Publication No. 15044/1986 discloses an operating member having an operating lever that opens and closes the main shutter of a tank by pushing and pulling, and a rotation adjustment rod that opens and closes a flow rate regulating valve by moving it forward and backward. The document describes a structure consisting of an operating member having:

(Problems to be Solved by the Invention) The above-mentioned known device has an operating lever that opens and closes the main shutter of the tank by pushing and pulling it, and a rotation adjustment rod that opens and closes the flow rate adjustment valve by moving it forward and backward.
It has a single dual-use structure.

Therefore, in the known system, when the main shutter of the tank is pushed or pulled to open or close, the flow control valve is moved forward or backward at the same time, and its position is changed.

The present invention allows the tank's main shutter and flow control valve to be adjusted separately.

(Means for Solving the Problem) The present invention has been devised so that the main shutter 3 of the tank 1 can be opened and closed by moving the operating member A with the operating lever 5 that pushes and pulls the main shutter 3 and the flow rate regulating valve 25 back and forth. The operating member B has a rotation adjusting rod 26 that allows the operating lever 5 to rotate.
A gear 8 is fixed to the rotation adjustment rod 26, an axially long gear 30 is fixed to the rotation adjustment rod 26, the gear 8 and the gear 30 are meshed, and the operating member B rotates when the operating member A is rotated. This is a feeding device for grain processing equipment, etc., which moves back and forth while moving.

(Example) An example of the present invention will be described with reference to the drawings.
2 is a tank of the grain conditioning and processing device, 2 is a drop tube at the lower end of the tank 1, and a main shutter 3 is provided at the top of the drop tube 2 to open and close the drop tube 2 by sliding horizontally. The outer end of the main shutter 3 is bent downward to form a bent part 4, and the bent part 4 has a linearly long operating lever 5 which is an operating member A.
The tip 6 of the holder is fixed so that it can only be rotated freely. The inner half of the operating lever 5 is formed into a simple round bar 7, and a gear 8 is fixed at an intermediate position of the round bar 7 with a stop 9.
10 is a stopper and holding metal fitting, whose inner end 1
1 is fixed to the drop tube 2, the outer end thereof is bent downward to form a bent part 12, and the outer end of the round bar 7 is slidably inserted into a through hole 13 bored in the bent part 12.
14 is a knob provided on the outside of the frame 15, and when the knob 14 is held and pulled, the gear 8 moves to the bent portion 1.
2 and stops, and the main shutter 3 becomes fully open. A spline groove 16 is formed in the outer half of the operating lever 5, and a gear 17 is fitted into the spline groove 16 so as to freely slide only.

The gear 17 does not come out of the spline groove 16 even if the knob 14 is pushed or pulled. A gear plate 18 with a flow rate memory that meshes with the gear 17 is engaged therewith,
When the knob 14 is rotated, a gear plate 18 with a flow rate memory is rotated via a gear 17.

19 is a window, 20 is a set screw, and 21 is a shaft, and the gear plate 18 with a flow rate memory rotates around the shaft 21. 22 is a holding plate, and 23 is a spring, which prevents blind movement of the gear plate 18 with flow rate memory.

Reference numeral 24 denotes a support shaft installed horizontally at the bottom of the main shutter 3 within the drop tube 2, and the upper end of the flow rate control valve 25 is pivotally attached to the support shaft 24. An operating member B is provided in the center of the lower surface of the flow control valve 25 in parallel with the operating lever 5.
The inner end 27 of the rotation adjustment rod 26 contacts the inner end 27 of the rotation adjustment rod 26 . A screw 28 is carved on the outer peripheral surface of the inner end side of the rotation adjustment rod 26, and the screw 28 is inserted into the screw hole 2 formed in the drop tube 2.
9. A gear 30 is formed in the middle part of the rotation adjustment rod 26, and the gear 30 is long in the axial direction, and the gear 8 meshes with it.Even if the operating lever 5 is pushed or pulled, the gear 8 and the gear 30 do not mesh. It doesn't come off.

The outer end of the rotation adjustment rod 26 is slidably fitted into a shaft cylinder 31 attached to the inner surface of the frame 15. 32
is a regulating plate, which is installed vertically, and is connected to the flow control valve 2.
5 is pushed by the inner end 27 and becomes approximately 45 degrees, the regulation plate 3
2 to prevent the grains from falling, and the flow control valve 2
Adjust the flow rate by opening No.5.

(effect) Next, we will discuss the effect.

Fill tank 1 with grain and turn knob 1.
When the gear 4 is pulled out, the spline groove 16 and the gear 17 are in a sliding relationship, and the meshing of the gear 8 and the gear 30 is free to slide. 12 and stops.

Then, the main shutter 3 becomes fully open, but the gear 8 and the gear 30 continue to mesh.
When the knob 14 is rotated in this state, the rotation is transmitted from the operating lever 5 to the gear 8 to the gear 30, and the rotation adjustment rod 26 is rotated. Since the screw 28 at the inner end of the rotation adjustment rod 26 is screwed into the screw hole 29 of the drop tube 2, the inner end 27 moves outward due to rotation, and the flow rate adjustment valve 25 is opened.

The rotation adjustment rod 26 can be smoothly moved because the rotation adjustment rod 26 and the shaft cylinder 31 are slidably fitted together.

Since the spline groove 16 and the gear 17 are engaged, the gear 17 rotates, rotating the gear plate 18 with a flow rate memory that meshes with the gear 17, and reading the memory written on the gear plate 18 with a flow rate memory. window 1
By reading from 9, the degree of opening and closing of the flow control valve 25 can be known.

(Effects) Conventionally known Japanese Utility Model Publication No. 38-15044 discloses an operating member having an operating lever that pushes and pulls the main shutter of the tank to open and close it, and a rotation control rod that opens and closes the flow rate regulating valve by moving it forward and backward. This document describes a structure consisting of an operating member.

The known device has an operating lever that opens and closes the main shutter of the tank by pushing and pulling it, and a rotation adjustment rod that opens and closes the flow rate adjustment valve by moving it forward and backward.
It has a single dual-use structure.

Therefore, in the known system, when the main shutter of the tank is pushed or pulled to open or close, the flow control valve is simultaneously moved forward or backward to change its position.

However, the present invention has an operating member A that has an operating lever 5 that pushes and pulls the main shutter 3 of the tank 1 to open and close it, and an operating member B that has a rotation adjustment rod 26 that opens and closes the flow rate regulating valve 25 by moving it forward and backward. The operation lever 5 and the rotation adjustment rod 26 are in a parallel state, a gear 8 is fixed to the operation lever 5, an axially long gear 30 is fixed to the rotation adjustment rod 26, and the gear 8 and the rotation adjustment rod 26 are arranged in parallel. gear 30
so that the operating member B engages with the operating member A.
This is a feeding device for grain processing equipment, etc., which moves back and forth while rotating when it is rotated. (a) When the operating member A is pushed and pulled, the main shutter 3 of the tank 1 can be opened and closed.

(b) When the operating member B is rotated, the flow control valve 25 is opened and closed independently of the main shutter 3.

C. When the operating lever 5 is rotated, the gear 8 and the axially long gear 30 mesh with each other, causing the rotation adjustment rod 26 to rotate while rotating the rotation adjustment rod 26.
is moved forward and backward to open and close the flow rate control valve 25.

It has a simple structure and can achieve the purpose of the invention.
