Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a soil kneading machine, and particularly to a soil kneading machine suitable for kneading wall soil.

In order to knead wall soil, etc., it is necessary to crush the soil clods and stir them while kneading them.However, with conventional mixers, it is not possible to crush the soil clods, so it is not possible to knead them into a certain paste-like state. It was impossible. The present invention has a stirring function, and
The purpose of this machine is to provide a soil kneading machine that is capable of kneading soil into a certain paste by having the function of crushing soil clods. A crushing soil stirring roller having a crushing cutter that is spaced at a predetermined interval and capable of moving at least in a direction away from the bottom surface is moved in a circular motion while rolling along the circumferential surface of a circular tank. A leveling member for uniformly leveling the soil put into the circular tank is provided to rotate in conjunction with the crushed soil stirring roller.

Hereinafter, a preferred embodiment of the present invention will be described in detail based on the accompanying drawings.

1 is the hopper 2 where the soil, water, etc. that will be used as wall soil etc.
It is a circular tank into which water is poured. A rotary shaft 3 connected to a suitable drive device (not shown) is rotatably disposed at the center of the circular tank 1, and a cover member 4 is provided at the protruding portion inside the tank 1.
is fixed. Reference numerals 5 and 6 denote attachment members having a U-shaped cross section and fixed to the cover member 4 of the rotating shaft 3, and their open surfaces face the bottom surface 1a of the circular tank 1 and extend in the radial direction thereof. positioned. These mounting members 5 and 6 are provided with screws 9, 10, and 1, respectively, so that the soil leveling members 7 and 8 are isolated from the tank bottom surface 1a for a predetermined distance.
1 and 12 are fixed, so that they can be replaced when the soil leveling members 7 and 8 become worn. 13,
Reference numeral 14 denotes a guide plate having an L-shaped planar shape fixed to the cover member 4 of the rotating shaft 3, and is evenly leveled in the tank 1 to a substantially uniform height by the soil leveling members 7 and 8. This guides the soil so that it is concentrated in the circumferential direction of the tank 1. Reference numerals 15 and 16 denote crushing soil stirring rollers, and a large number of crushing soil cutters 15c and 16c extend parallel to the axis to be located on the peripheral surface between disks 15a and 15b, which are located parallel to each other, and between the disks 16a and 16b. Fixed. Each of the crushed soil stirring rollers 15 and 16 is arranged on a support shaft 1 so as to be located slightly below the soil leveling members 7 and 8 with respect to the tank bottom surface 1a.
7 and 18 via appropriate bearing members so as to be rotatable. Each of these support shafts 17,
18 are provided with protruding shafts 17a and 18a that protrude perpendicularly to their axes, and these protruding shafts 17
a, 18a are a pair of bearing parts 19, 20 and a pair of bearing parts 21, 22 fixed to the cover member 4;
are supported by each. Reference numerals 23 and 24 denote a pair of regulating plates for regulating the horizontal swinging of each of the support shafts 17 and 18. Therefore, each of the support shafts 17, 18 has their protruding shafts 17a, 1
It can swing freely in the vertical direction along each of the regulating plates 23 and 24 using 8a as a fulcrum, and its downward swinging is regulated by the cover member 4. As the supporting shafts 17, 18 swing, the crushed soil stirring rollers 15, 16 are also movable at least upwardly. Note that 25 is a chute for discharging the kneaded soil to the outside of the tank 1.

The operation when kneading the wall soil in this embodiment configured as above will be explained.

First, an appropriate amount of the collected wall soil and water are put into the tank 1 from the hopper 2, and the drive device (not shown) is started as appropriate to rotate the rotating shaft 3 in the clockwise rotation direction in Figure 1. let Along with this rotation, each soil leveling member 7, 8, each guide plate 13, 1
4 and each crushed soil stirring roller 15, 16 also start circular motion in the same direction. Here, the soil leveling members 7 and 8 average the raw soil that is ubiquitous in the tank 1, and then the guide plates 13 and 14 level the raw soil that is omnipresent in the tank 1, and then the guide plates 13 and 14
That is, the crushed soil is sent out toward the moving parts of the crushed soil stirring rollers 15 and 16. Each of the crushed soil stirring rollers 15 and 16 crush this sent-out raw soil and mix it with water.
The support shafts 17 and 18 are fixed due to contact resistance with the original soil.
By rotating in a circular motion around the axis,
The soil crushing cutters 15c, 16c crush the soil and take it into the rollers 15, 16, where it is crushed again by the soil crushing cutters 15c, 16c, and the soil clods are crushed by the rollers 1.
5 and 16, the process of releasing the water to the outside will be repeated. Therefore, the raw soil for earthen walls is crushed into lumps within a short period of time, and mixed with water to reach the desired paste state. Once this condition is reached, a predetermined amount of ivy, or small pieces of straw cut into 5 cm pieces, is added to prevent cracks in the walls and promote ventilation. The ivy is uniformly mixed into the pasty soil by the rotational circular motion of the crushed soil stirring rollers 15 and 16 as described above.

In this way, appropriate amounts of original soil, water, and ivy are gradually poured into tank 1 to knead a predetermined amount of wall soil, but the maximum amount is determined by the soil volume height position within tank 1. Each crushed soil stirring roller 15, 16
, that is, each support shaft 17, 18
limited to quantities located further down. When the amount of soil exceeds this limited amount, each crushed soil stirring roller 15, 16
This is because it becomes difficult to rotate and the desired effect cannot be achieved. In addition, although the raw soil may contain foreign matter such as stones, when the crushed soil stirring rollers 15 and 16 come into contact with these foreign matter that cannot be crushed, each of the soil is rotated using the protruding shafts 17a and 18a as fulcrums. The soil crushing cutters 15c, 16 can escape by swinging the support shafts 17, 18 upward.
There is no risk that c will be damaged. Furthermore, once these foreign objects sink to the bottom of tank 1, the bottom surface 1
The soil leveling members 7, 8 and the crushed soil stirring rollers 15, 16, which are located a predetermined distance away from a, will never collide with each other again, and even when the wall soil that has been kneaded is discharged to the outside of the tank 1, there will be no foreign matter in it. will not be contaminated.

Although various explanations have been given above with reference to a preferred embodiment of the present invention, the present invention is not limited to this embodiment, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.

In this way, according to the present invention, the degree of stickiness is high;
It is possible to efficiently knead raw soil such as wall soil that contains foreign matter, and since the crushed soil stirring roller is formed to be able to swing upwards relative to the rotating shaft, the load when the crushed soil stirring roller escapes from foreign matter is reduced. is not applied to the rotating shaft, which has the remarkable effect of preventing damage to the rotating shaft.
