Description

The utility model relates to the field of agricultural and construction units, namely to vehicles for transporting and unloading various materials.

A snowmobile-towing vehicle is known from the prior art (patent RU 198517, publ. 14.07.2020 Bull. No. 20), including a support frame equipped with a caterpillar mover, on which a walk-behind tractor is mounted, kinematically connected to the latter, and the frame is equipped with a hitch device with drag sleds , the support frame consists of a horizontal platform with a walk-behind tractor fixed at its front end, the engine of which is connected by means of a chain transmission to the front axle of the caterpillar, and along the longitudinal axis of symmetry of the platform in its middle part and behind the walk-behind tractor, a hitch device is installed, which, with the help of a beam carrying the seat for the driver, connected with the drag sled. The disadvantage of this design is the low transported weight, the impossibility of using in the summer (sleigh drags are not used in the summer), the presence of a chain transmission (requires constant monitoring).

Known motoblock-snowmobile (patent RU 115997, published: 20.05.2012 Bull. No. 14). Technological equipment is removed from the drive shaft of the walk-behind tractor and a caterpillar mover is installed. The caterpillar drive shaft is rotated by the drive and transmits rotation through a chain or belt drive to the caterpillar drive sprocket. The disadvantage of this design is the presence of a chain transmission, this option does not move the load by itself, this requires an additional trailer.

The closest in technical essence is a caterpillar transporter with a mechanism for loading and unloading cargo (patent RU 206017, publ. 08/16/2021 Bull. No. 23), which contains a video camera, a remote control unit located on a spatial power frame, with remote receiving and transmitting antennas , a body made with the possibility of unloading to the right, left, forward and backward by means of a hydraulic tipping device, left and right caterpillar movers, including a guide wheel with a track chain tensioning mechanism, a carriage with track rollers, support rollers, and a drive roller. Moreover, caterpillar propellers are mounted on a spar having a rigid connection with a spatial power frame using telescopic racks, made with the ability to work in pairs through a connecting element, the outer tubes of which are part of a spatial power frame, and the inner tubes can be extended using a connecting element and transfer screw - a nut that converts the rotational movement from the electric motor shaft of the gauge change mechanism into translational movement of the inner tubes along the guide grooves of the outer tubes of the telescopic rack. The power plant is made in the form of a motor-wheel, and the remote control is equipped with controls and an LCD display, which displays the image from the video camera, information about speed, battery charge, approximate range on the current charge, as well as power consumption. A caterpillar transporter with a mechanism for loading and unloading cargo includes a mechanism for loading and unloading cargo, consisting of a winch, the connection of which to the body of the caterpillar transporter is provided by means of winch mounting, and the winch is driven by an electric motor of the mechanism for loading and unloading cargo, which transmits rotational motion through the shaft to the gearbox , which, in turn, rotates the drum, which ensures the winding of the cable on itself, with the help of which the transported load is hooked, and the cable is fixed in the required position by means of a latch, the front side of the body of the caterpillar transporter is made with the possibility of overturning by means of a cylindrical hinge, while performing the function guide element, and the unloading of the transported cargo from the body is carried out with a hooked cable on the opposite side of the load, and the cable passes through the guide block, which is rotatable about the axis of the thrust th bar, fixed on the front side of the body by means of a bar attachment, by means of a bearing of the guide block, while the motor-wheel, the remote control unit, the electric motor of the gauge change mechanism and the electric motor of the cargo loading and unloading mechanism are powered by a battery. The disadvantage of this design is its complexity, the inability to independently load and unload cargo into the body of a caterpillar transporter.

The task to be solved by the claimed utility model is the development of a self-propelled wheelbarrow that is easy to assemble and disassemble.

This problem is solved by the fact that the caterpillar modular device consists of the right and left caterpillar attachments, a body with a frame, while the crawler attachment includes a frame made of shaped pipes welded together, a drive wheel, rollers and an endless flexible rubber caterpillar, while on the frame has shafts on which the drive wheel and rollers are attached, the frame has welded parts of pipes in which mating parts of the body frame are installed and fixed, the body frame is a spatial structure made of welded together parts of shaped pipes, on which the body is fixed, and having mating parts for fixing on the frame of the caterpillar attachment.

The technical result provided by the above set of features is the versatility of the design, suitable for any type of walk-behind tractor.

The utility model is illustrated by drawings, which show

in fig. 1 - side view of the device;

in fig. 2 is a top view of the device.

Tracked modular device consists of right and left track attachments 1 and body 2 with frame 3.

Caterpillar attachment 1 includes a frame 4, a drive wheel 5, rollers 6 and an endless flexible rubber caterpillar 7 with a main inner surface and spaced links protruding from it.

Frame 4 of the caterpillar attachment is made of shaped tubes welded together. Shafts are welded to the frame, on which rollers are put on through bearings, which rest and roll along the caterpillar during movement. Also, the drive wheel 5 is fixed on the frame. Two parts of the pipe are welded on the frame perpendicular to the square pipe, into which the mating parts of the body frame are inserted. The drive wheel is connected to the shaft (axle) of the walk-behind tractor gearbox. The connection of the motor block gearbox shaft and the drive wheel shaft is fixed with a bolted connection.

The frame 3 of the body is a spatial structure made of welded together parts of shaped pipes designed for installation and fastening of the body on it, and has parts that are inserted into the holes in the frame of the caterpillar attachment. Frame 3 of the body is inserted with a profile pipe into the caterpillar frame and is fixed by bolting in two places. There is a tensioner for tensioning the caterpillar.

A caterpillar with a lantern gear and internal guides is put on the drive wheel and rollers, and the caterpillar is tensioned.

The body is a rectangular container with a beveled front for easy unloading of cargo and is bolted to the frame. Body movements up and down are carried out thanks to a special elongated lever in manual mode.

This self-propelled wheelbarrow does not have in its design hydraulic, pneumatic units, sprockets, chain transmission, additional reduction or increase gearboxes, or gearboxes. Forward / backward movement is carried out exclusively with the help of a walk-behind tractor / motor-cultivator and its gearbox. Operator power is used to turn.

The device is used as follows.

Caterpillar attachments with a frame with a body are put on the drive shafts of the walk-behind tractor gearbox. The cargo is placed in the body for transportation. When the drive shafts of the walk-behind tractor rotate, the drive wheel of the caterpillar drive is set in motion and the walk-behind tractor on the caterpillar drive starts moving. When reaching the destination, the body tips over by the handle.
