Description

Pattern description

The subject of the utility model is an attachment for filling flood protection bags with sand based on a self-unloading trailer. From the American patent US 5,425,403, a device for filling bags with loose or granular material, especially sand, is known, which is equipped with a vertical tank from which, through a horizontal motor-driven screw conveyor, material is poured into bags, which are placed around the discharge opening and from at the bottom supported by an adjustable horizontal shelf. The device is equipped with a system for regulating the amount of material poured into the bag. The frame of the device is equipped with wheels and an adjustable support that allows to set the device on uneven ground.

Also known from European patent specification EP 1338510 is a device for filling bulk material into containers, especially bags, which has a hopper with a filling pipe attached at the bottom, in which is coaxially arranged, loose material, especially sand, intended for flood protection purposes, axially movable and a rotatably conveying element, the lower end of which is permanently connected to an axially displaceable and rotatable closing element at the lower end of the filling tube. The aim of the invention is to solve a simple and dismantleable and easy to use and install anywhere, device for filling sand bags in large amounts in a short time, especially during flood control actions. The device for filling bags with loose material, in particular sand, according to the invention is characterized by the fact that it has operating arms, each of which has a rotating container at one end, equipped with a bag catch, and a locking-releasing mechanism for the container rotation is mounted to each operating arm, and the other end of the arm is connected to a head equipped with a drive and rotatably mounted on a column placed on the feet.

A device for filling bags with loose material, especially sand, is known from the Polish patent Pat. 210299. The subject of the invention is a device for filling bags with loose material, especially sand, intended for flood protection purposes. The device has operating arms, each of which has a rotating container at one end, equipped with a bag catch, and each operating arm has a locking mechanism that slows down the container rotation, and the other end of the arm is connected to a head equipped with a drive and seated. rotatingly on a column set on feet. The mechanism that locks-releases the rotation of the container is a bar mounted on the operating arm slidably in the guides, subject to the action of a spring, one end of which cooperates with a recess made in a stop element attached to the container, and the other end cooperates with a pull-back element connected to the stationary part of the device.

The essence of the utility model is an attachment for filling flood protection bags with sand, having a sand container, with a piston dispensing sand with a double-acting cylinder for the bags. By means of a distributor mounted on the tractor, the oil is directed to the double-acting cylinder, which causes the sand dosing piston to move to the right or left. Moving the spreader belt causes sand to be poured into the container of the attachment. Then, under the influence of its own weight, the sand goes to the inlet opening of the sand dosing pipe. The displacement of the piston rod of the actuator causes the simultaneous displacement of sand, which ends up in the bags.

The attachment according to the utility model is used to fill the flood control bags with sand, which will be used to build flood banks. The attachment is characterized by a simple and compact structure as well as uncomplicated operation. Thanks to the two-sided filling system, the designed attachment will be characterized by high efficiency.

The object of the utility model is shown in the drawings, where Fig. 1 shows the attachment for filling flood protection bags attached to the dumping trailer, and Figs. 2, 3, 4 and 5 show the attachment in perspective views.

The sand dosing system automatically determines the mass of sand, which is 25 kg, so that each bag will have the same weight after being filled. • device capacity: 900 bags / h, • bag dimensions: 0.5 x 0.6 m, • weight of the bag filled with sand: 25 kg,

Claims (2)

• drive by means of a hydraulic actuator driven from the agricultural tractor's hydraulic system, • quartz sand bulk density: 1600 kg / m3, • dimensions of sand pouring into the dispenser: 0.25 x 0.25 m, • material for sand dosing piston: alloy steel, • wall thickness of the device: 0.005 m, • adaptation of the attachment to the tractor's hydraulic system with a capacity of 80 l / min. The attachment for filling flood protection bags with sand has a container 1 with sand 2, which by means of a piston 3 dispenses sand 2 with a double-acting cylinder 4 into the bags 5. The oil is directed to the double-acting cylinder 4 by means of a distributor mounted on the tractor, which moves it to the right or left of the sand dosing piston 3. Moving the spreader belt causes the sand to be poured into the container of the attachment 1. Then, under the influence of its own weight, the sand goes to the inlet opening of the sand dosing pipe. The displacement of the piston rod of the actuator causes the simultaneous displacement of the sand 2, which goes to the bag 5. Protective reservations 1. Attachment for filling sand bags with sand, characterized by the fact that it has a sand container (1) (2), and below it, an actuator (4) with a piston (3) dispensing sand (2) to the bags (5). 2. The attachment according to claim A device as claimed in claim 1, characterized in that the attachment for filling the flood protection bags with sand is set to a loading trailer.
