SU802445A1 - Device for making wind-permeable wind-permeable snow-retaining fences in the form of snow posts - Google Patents

Description

The invention relates to the field of snow retention, and in particular to devices for creating snow retention fences. A device is known for creating ^e- blown snow-retaining fences in the form of columns, containing a frame hooked to the base machine, on which a gripping mechanism, snow ... and a pressing matrix made of two halves sliding with hydraulic cylinders are mounted [1J.

The disadvantages of the device are the low productivity of the construction of fences and the lack of stability of the snow columns.

The aim of the invention is to increase the performance of the construction of fences and the stability of the snow.

columns. . 20

This goal is achieved by the fact that in the device for creating purged snow-holding barriers in the form of columns of snow, containing __ a frame hooked to the base machine, on which are mounted a snow gripping mechanism and a pressing matrix made of two halves sliding with hydraulic cylinders, a gripping mechanism the snow is equipped with a transformer for feeding snow into the matrix, which is equipped with a punch located in its upper part and a trolley mounted on longitudinal guides made on the frame, while the trolley is connected on a rope with a winch equipped with a brake.

In addition, the cross section of the matrix is rectangular, which allows to increase the windproof shadow of the fence.

In FIG. 1 shows a device, side view, in FIG. 2 - the same, top view; in FIG. 3 is a view along arrow A of FIG. 1, the halves of the matrix are shifted) in FIG. 4 - the same, the halves of the matrix are apart.

The device comprises a frame 1 mounted on skis attached to the base machine (not shown in the drawings)

2. A snow pick-up mechanism 3 is mounted on the frame in the form of a foot feeder, which is connected via a conveyor 4 to a hopper 5 located above the pressing die 6. The matrix is made up of two halves 7 connected to their hydraulic cylinders 8 and equipped with support rollers 9, placed in the transverse rails 10 of those beds 11, which are installed. on the longitudinal rails 12, made on the frame 1. B. the upper part of the matrix in the hopper 5 is placed a punch 13 mounted on the rod of the hydraulic cylinder

14. The truck 11 using the ropes 15 is connected with the drums 16 of the winch, which is mounted on the frame 1 and is equipped with a drive including a hydraulic motor 17, a gearbox 18, a fluid coupling. 19, the chain gear 20 and the brake 21. The foot feeder 3 and the conveyor 4 are driven from the gearbox 18 through the fluid coupling 22 and the driveshaft 23.

The device operates as follows.

When towing the device on virgin snow, the snow is captured by the paw feeder 3 and fed via the conveyor 4 to the hopper 5, from where it is poured into the matrix 6. The punch 13 is at the top point, without interfering with the snow supply to the matrix, and the trolley 11 is in the far left position (see figure 1). filling the matrix with snow, the conveyor 4 and the feeder 3 are turned off. At the same time, pressure is applied to the hydraulic cylinder 14 to move the punch 13 and the winch brake 21 is released.

Due to the adhesion of the pressed snow column with the soil, the trolley 11 stops, and the frame 1 continues to move, unwinding the ropes 15. at the end of the punch stroke, when the required density of the snow column is ensured, the hydraulic cylinder 14 switches to the reverse stroke and at the same time pressure is applied to the hydraulic cylinders 8, the spreading halves 7 of the matrix.

Then the fluid coupling 19 and the trolley 11 are turned on with the help of ropes 15, wound around the drums 16, moves along the frame 1 to its original position (leftmost in Fig. 1). After this, the hydraulic coupling 19 is disconnected; the brake 21, the hydraulic cylinders 8. are turned on, shifting the halves of the matrix 6, and the hydraulic coupling 22, which transmits torque to the feeder 3 and to the conveyor 4, which supply snow to the matrix. Then the cycle repeats.

This device allows you to create a fence in the form of columns of snow with its continuous movement _f, which significantly reduces the time required to erect the fence. In addition, due to the pressing of snow columns to the soil, their reliable adhesion is ensured, which increases the stability of snow columns during their formation and in the process of snow retention.

(54) DEVICE FOR CREATING purged SNEGOZADERZHIVAKHTSIH fence in the form of columns of the snow maturation 11 which ustanovlena.na of longitudinal guides 12 / made on the frame 1. V.verhney part of the matrix in the hopper 5 is placed punch 13 mounted on the cylinder rod 14 The trolley 11 is connected with ropes 15 to the winch drums 16, which is mounted on frame 1 and equipped with a drive including a hydraulic shaft 17, a gearbox 18, a hydraulic clutch, 19, a chain drive 20 and a brake 21. Lapovy feeder 3 and conveyor 4 is driven by gear 18 through gi emufta 22 and the propeller shaft 23. The device operates as follows. When towing the device along the snow virgin snow, the snow is caught by the lap feeder 3 and by means of the conveyor 4 is fed into the bunker 5, from where it is poured into the matrix 6. In this case, the punch 13 is at the top, not the obstacle to the supply of snow to the matrix, and the carriage 11 is in the leftmost position, see figure 1 When the matrix is filled with snow, the conveyor 4 and the feeder 3 are turned off. At the same time, pressure is applied to the hydraulic cylinder 14 to move the punch 13 and the brake 21 of the winch is turned off. Due to the adherence of the compressible sleeper to the soil, the carriage 11 stops and frame 1 continues to move, unwinding the ropes 15. At the end of the punch stroke, when it provides the required density of the snow post, the hydraulic cylinder 14 switches to the reverse stroke and at the same time pressure is applied to hydraulic cylinders 8, pushing the halves of the 7 matrix. The fluid coupling 19 is then turned on, and the carriage 11, with the aid of ropes 15 winding on the drums 16, is moved along pc1me 1 to the initial attachment (at the extreme left in Fig. 1). After this, the fluid coupling 19 shuts off the brake 21 and turns on the hydraulic cylinders 8., shifting the halves of the die 6, and the fluid coupling 22, which transfers torque to the feeder 3 and to the conveyor 4, which feed the snow into the die. Then the cycle is repeated. This device allows you to create a fence in the form of columns of snow during its continuous movement, which significantly reduces the time required for the construction of the fence. In addition, due to the pressure of the snow pillars to the soil, their grip is secured, which increases the stability of the snow pillars during their formation and during snow retention. Claim 1.
