Description

[Detailed description of the invention] Industrial application field The present invention is used in civil engineering work, agricultural work, etc. to separate gravel and soil attached to the gravel, or to crush soil clods mixed in the gravel. This invention relates to improvements in sorting equipment for civil engineering, agriculture, etc., which separates stones from gravel.

Conventional technology Conventionally, this type of sorting device was
There is one shown in Publication No. 40451. In this device, a plurality of flanges are fixed to the outer periphery of a rotating drum at regular intervals at right angles to the rotary drum, and a plurality of these rotary drums are arranged in a row, and the flanges are adjacent to each other between the flanges of one of the rotary drums. The flanges of the other rotating drum are fitted into each other to form sieve mesh between the flanges of each rotating drum.

Problems to be Solved by the Invention The above-mentioned conventional device uses a collar fixed to each rotating drum to separate stone gravel and soil attached to the stone gravel, or to separate soil clods mixed in the stone gravel. It is used to crush and separate stone and gravel, but once crushed and sorted between the flanges of each rotating drum, the soil and clods are separated from the sieve mesh formed by the spacing between the flanges. It falls down instantly, and while it rolls around stones, gravel, sand, clods, etc., it cannot rub or pound evenly and repeatedly, and there is a limit to its ability to sort and crush earth, sand, clods, etc., resulting in poor work efficiency. There are problems.

The present invention was developed by focusing on the above-mentioned problems, and is a useful sorting method that can evenly and repeatedly rub and pound earth and sand and clods while rolling them, and reliably sort and crush them. The purpose is to provide equipment.

Means for Solving Problems In order to achieve the above object, the present invention provides broken parts spirally around the circumferential surfaces of a large number of rotating shafts, so that the broken parts of adjacent rotating shafts extend over the length of the rotating shafts. To provide a sorting device for civil engineering and agriculture, in which a large number of rotating shafts are installed in parallel to a machine frame so that they are arranged alternately in the direction and the tips of the crushed parts engage with each other. .

Effects of the present invention: When a large number of rotating shafts are installed parallel to the machine frame as described above, the crushed parts spirally arranged around the circumferential surface of the rotating shafts are arranged alternately in the length direction of the rotating shafts. , and because the tips of the crushed parts are arranged to interlock with each other, by rotating the rotating shaft, stones, gravel, earth and sand (clay, wet soil, and their lumps) sent onto the crushed parts can be removed. ) are rubbed by the crushed parts,
The earth and sand are separated from the stones and gravel by being hit, and the earth and sand are simultaneously crushed and fall downward, and the stones and gravel are sent to the discharge port and discharged. On the other hand, the roots of agricultural crops and grasses fall downward from between the crushed areas together with crushed soil and return to fields and pastures. Since the crushed part is spirally arranged around the circumferential surface of the rotary shaft, when the rotary shaft is rotated, the stones and gravel that have been sent are rolled and rubbed evenly and repeatedly. By rubbing and pounding, it is possible to efficiently crush clay, wet soil, and their lumps, and also to shake them out, allowing efficient sorting work to be carried out without fear of clogging.

Embodiment To explain FIGS. 1 and 2 of the drawings, there is a broken part 2 made of studs on the circumferential surface of a large number of rotating shafts 1.
A sprocket 4 is attached to one end or both ends of the rotating shaft, and a chain 5 is arranged around the rotating shaft. The crushed portions 2 are made of studs and are arranged around the circumferential surface of the rotating shaft 1 in a spiral arrangement. The crushing part 3 is the crushing part 2
A large number of rotating shafts 1 are installed around the circumference of the motor, and motors 6 are installed at appropriate locations. The configuration is such that the information is transmitted to the rotating shaft 1.

A large number of rotating shafts 1 are installed parallel to the machine frame 3 so that the broken parts 2 of the adjacent rotating shafts 1 are arranged alternately in the length direction of the rotating shaft 1, and the broken parts 2 of the neighboring rotating shafts 1 are By installing the parts 2 in parallel to the machine frame 3 so that the tips thereof are in an interlocking arrangement, and rotating the rotating shaft 1, stones, gravel, earth, etc. sent onto the crushing part 2 can be rolled. While moving, it is possible to rub and beat evenly and without any damage, and the interval between the broken parts 2 of each adjacent rotating shaft 1 is such that the roots of crops and grass can pass through and fall. It is installed parallel to the machine frame 3 so that the roots do not mix with the stones and be unnecessarily discharged. By changing the number of rotations of the multiple rotating shafts 1, the number of rotations of the crushing section 2 can be changed, thereby changing the amount and speed of passage of stones, gravel, soil, agricultural crops, grass roots, etc. sent onto the crushing section 2. etc. can be changed.

FIG. 3 shows another example of a sorting roller made of a single long plate in which a crushing part 2 is provided on the circumferential surface of a rotating shaft 1 in a spiral manner, and in this example, a large number of rotating shafts 1 are It is installed parallel to the machine frame 3 in the same manner as in the previous example.

[Brief explanation of the drawing]

FIG. 1 is a partially cutaway plan view of the sorting device of the present invention, FIG. 2 is a longitudinal sectional side view thereof, and FIG. 3 is a perspective view showing another example of the crushed portion. In the figure, 1... rotating shaft, 2... crushed part, 3... machine frame.

Claims (1)

[Scope of utility model registration request] A sorting device for civil engineering and agricultural use, in which crushed sections are spirally provided on the periphery of a number of rotating shafts, the crushed sections of adjacent rotating shafts are arranged alternately in the longitudinal direction of the rotating shafts, and the crushed sections are mounted in parallel on a machine frame so that the tips of the crushed sections mesh with each other.
