Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to a millstone crusher for grinding raw materials such as grains, tea confectionery, medicinal herb roots, and waste materials. .

[Prior art]

Conventional stone mills for grinding grains, etc. are classified into two types: upper-white rotation type and upper-white rotation type.

In the former case, as shown in FIG. 1, an upper part 3 is rotatably placed on an upper part 2 fixed to a support stand 1, and driving force is applied from a motor 4 to a belt 5. Transmission is transmitted to the main shaft 7 via the pulley 6, and the upper white 3 is rotated by the main shaft 7 passing through the lower opening 2. The gap between the lower opening 2 and the upper white 3 is adjusted by operating the clearance adjustment handle 8. Adjustments are made by raising and lowering the main shaft 7 via a lever 9 and raising and lowering the 13. The raw material supplied from the raw material input port 10 at the top of the upper part 3 is passed through a passage 11 eccentric to the main shaft 7. It is supplied to the gap between both ports 2 and 3.

This format is 1. The number of rotations is approximately 20 because it is driven by an upper mill.
The grinding speed was as low as ~40 r, p, m, resulting in poor workability and the fact that the raw material was fed eccentrically, resulting in a small effective grinding area.

The latter was developed to improve upon this drawback.

In the latter case, as shown in FIG. 2, a cover 1a of the support base 1 is attached with a top white 3 on top of a lower opening 2 which is rotatably arranged on the support base 1.
The driving force from the motor 4 is applied to the belt 5. It is transmitted to the main shaft 7 via the pulley 6, and this main shaft 7
The gap between the lower opening 2 and the upper white 3 is adjusted by operating the clearance adjustment handle 8 and moving the main shaft 7 up and down via the lever 9 to raise and lower the lower opening 3. The raw material fed from the raw material input port 10 in the clay part of the upper white 3 is fed through a senter through a passage 11 arranged coaxially with the main shaft 7.

゛This type has a top white drive, so the number of rotations is approximately 20.
The speed was increased to 0 to 300r, pom, which improved workability and expanded the effective grinding area, but the quality of the material to be ground was inferior to the former, and both had a fixed rotation speed. Therefore, in order to carry out rough grinding to finish grinding in order, it was necessary to have both grinding machines in place, and in both cases, the grinding pressure was adjusted by adjusting the weight of the -F mill and the fixed weight.

[Purpose of the invention]

In view of the above points, the present invention enables rotary drive from low speed to high speed, allows easy adjustment of the gap between the two wheels, prevents damage to the mortar even when foreign objects are bitten, and reduces grinding pressure. We offer a rotary stone mill that is easy to set up.

The outer teeth 33b formed on the lower outer periphery of the member 33 mesh with the inner m31a of the ring gear 31.

At least three or more gap adjustment members 33, four in this embodiment, are provided so that the lower openings 23 can be moved up and down evenly.

A crushing pressure adjusting shaft 34 is screwed into a normal thread 33C formed in the cylinder of the gap adjusting member 33 so as to be movable in the vertical direction by a male thread 34a shown in A, and is inserted into the lower end of the shaft 34. The ring gear 31 is supported on the bottom wall 22a of the support base 22 by a cock nut 36 screwed onto the seat plate 35 and the male screw 34a, and a clearance adjustment handle 37 provided on the ring gear 31 is attached.
By operating the gear 31, the gear 31 rotates. The upper end of the grinding pressure adjustment shaft 34 is inserted into a shaft hole 38 formed at the bottom of the lower opening 23, and is engaged with the upper end step 34b to restrict vertical movement. Adjustment member 33
A spring 40 is elastically loaded between the upper end and the support plate 39 to elastically support the lower opening 23.

A raw material input port 41 is provided at the upper part of the upper white 24, and the raw material supplied from the port 41 is fed centered through a passage 42 formed between the 1E124 and the periphery of the main shaft 26, and then fed to the bottom. After being crushed in the gap between the mouth 23 and the upper white 24, it is taken out from the outlet 43 provided on the side of the lower mouth 23.

Next, we will explain the operation of the upper stone crusher.

First, the F end of the crushing pressure adjustment shaft 34 is operated to rotate the shaft 34, and the male thread 34a and the female thread 33 of the clearance adjustment member 33 are rotated.
The elastic force of the compressed spring 40 is reduced by moving the shaft 34 up and down as it is threadedly engaged with G, and adjusting the distance between the upper end step 3/Ib of the shaft 34 and the upper end of the gap adjustment member 33. change,
