MACHINE FOR DISTRIBUTION OF LANDING MATERIALS ||

M. KL.7E01S19 / 20 The noisy model relates to the content of the roadway in winter. A sand spreader is known (see USSR author's certificate No. 1199853 M. class E 01 C 19/20), consisting of a removable frame mounted on the chassis of the base machine with a transfer hopper with a feed conveyor and a spreading device (disk). Supporting brackets with roller bearings located below the spreading disc are fixed on the removable frame, and a cable winch is fixed on the base machine to tighten the removable hopper frame to the lifting frame of the base machine. If necessary, the removable frame with the hopper with the help of a cable winch can be lowered to any platform without destroying the spreading disk, since when lowering the removable frame it rests on the roller bearings of the brackets. The disadvantages of the well-known gritters should be considered the installation of a special winch on the base machine and the inability to use a conventional vehicle with a lift as the base machine

The closest in technical essence are machines of the type of distributor MMOP (see prospectus of CJSC Medmeta “Distributor of anti-ice materials MM011).

In such machines for a bulk material distributor, a removable hopper with a conveyor and a spreading disc and telescopic supports in the area of the spreading disc is additionally equipped with pivotally mounted supports in the middle of the hopper and rollers in the front of the hopper at the level of its supporting surface. Outside the base machine, the removable hopper is supported by telescopic legs extended to the extreme position in its rear part and articulated supports in the middle part.

Installing a removable hopper on the base machine is carried out by reversing it with a slightly (10-15) raised body. At the same time, the underbody first touches the rollers in the front of the hopper, which rises with further movement of the machine, the pivotally mounted supports in the middle part come off the surface and fold down. When lowering the body of the base machine, the rear supports of the hopper also come off and can be lifted.

Fastening the removable hopper to the chassis of the base machine to prevent it from slipping is carried out by lanyards (folding screws).

The disadvantages of the prototype include the long installation time of the removable hopper due to improper mutual orientation of the base machine and the removable hopper, as well as poor attachment of the hopper, especially when mounted on the hopper with powerful vibrators oriented in the longitudinal plane.

The purpose of the proposed utility model is to eliminate the disadvantages of the prototype.

This goal is achieved by the fact that in the rear part of the car body below its bottom a bracket with a hole is fixed, and an emphasis is installed under the supporting surface of the hopper. In addition, the emphasis can be full in the form of a spike wedge-shaped in the transverse plane.

In FIG. 1 shows schematically the position of the body of the base machine and the hopper at the beginning of the installation.

In FIG. 2 shows the position of the body and the hopper at the end of its installation. FIG. 3 shows a variant of the working position of the body with a hopper. On fi. Fig. 4 shows the relative position of the hopper-fixing parts. The machine for distribution of materials consists of a base machine / with a sub-bed body; rollers 9. The bracket 10 with the hole // is mounted on the body 2 below its bottom, and under the supporting surface of the hopper there is a stop 12 in the form of a wedge-shaped spike.

In the initial stage of installation of the removable hopper 3, the inclined body 2 raises it through the rollers together with the hinged supports 8, which are placed in the body. In the final stage of installation, the hole 11 of the bracket / is located under the emphasis / 2

When lowering the body 2, the bracket / rises, and the stop / is allowed in the hole //, fixing the position of the hopper 2 in the center of the body of the base machine without additional maneuvers.

When working machines for the distribution of bulk materials (sand distributors), there is often a freezing (arching) of bulk materials in the rear of the hopper 3, which is eliminated either with the help of a vibrator 4 of an unbalanced type in the longitudinal plane of symmetry of the hopper, or when the machine for the distribution of bulk materials is raised ( up to 20-300) with the body D, which is possible with the articulation of the spreading device (disk) 8, which can be mounted parallel to the road plane for any inclination of the body 2. IN THESE CONDITIONS Ovia sharply increase the load on the stop / and bracket 10, preventing the sliding of the removable hopper 3 from the body 2.
