Description

Изобретение относится к строительству и предназначено для механизации отделочных работ, преимущественно для приема, перемешивания и транспортировки штукатурного раствора к рабочим местам.The invention relates to construction and is intended for the mechanization of finishing work, mainly for receiving, mixing and transporting plaster mortar to workplaces.

Известна штукатурная установка, содержащая приемный бункер с ситом, перегружатель и растворонасос fjj .Known plaster installation containing a receiving hopper with a sieve, a reloader and mortar pump fjj.

Однако эта установка имеет небольшую производительность ввиду малого объема приемного бункера. При увеличении объема приемного бункера раствор плохо поступает к перегружателю.However, this installation has low productivity due to the small volume of the receiving hopper. With an increase in the volume of the receiving hopper, the solution poorly flows to the reloader.

Наиболее близкой к предлагаемой является штукатурная установка,включающая кабину, приемный бункер с шнеком-питателем и ситом,встроенным в 20 его днище, перегружатель и растворонасос и.Closest to the proposed is a plaster installation, including a cabin, a receiving hopper with a feeder screw and a sieve built into its 20 bottom, a reloader and a mortar pump.

Недостатком этой установки является невысокая производительность.The disadvantage of this installation is its low performance.

• Цель изобретения - повышение производительности и улучшение условий труда.• The purpose of the invention is to increase productivity and improve working conditions.

Поставленная цель достигается тем, что в штукатурной установке, включающей кабину, приемный бункер с шнеком-питателем и ситом, встроенным в его-днище, перегружатель и раст· воронасос, приемный бункер снабжен внутри дугообразной лопаткой,обращенной выпуклой стороной к ситу, подпружиненной одним концом, а другим шарнирно соединенной с днищем бункера, вал шнека-питателя оснащен стойками с горизонтально расположенными роликами, взаимодействующими с лопаткой, причем лопатка выполнена перфори· рованной.This goal is achieved by the fact that in a plastering installation, including a cabin, a receiving hopper with a feeder screw and a sieve integrated in its bottom, a reloader and a squeegee pump, the receiving hopper is equipped with an arcuate blade inside, with a convex side facing the spring loaded at one end and another pivotally connected to the bottom of the hopper, the feeder screw shaft is equipped with uprights with horizontally located rollers interacting with the blade, and the blade is perforated.

Штукатурная установка состоит из приемного бункера 1, соединенного перегружателем 2с растворонасосомThe plastering unit consists of a receiving hopper 1 connected by a reloader 2c with a mortar pump

3. Последний установлен в кабине 4 моториста. Вал 5 шнека-питателя соединен клиноременной передачей с электроприводом 8.В днище 9 приемного бункера 1 над входом в перегружатель 2 смонтировано сито 10. На палу. 5 закреплены стойки 11 горизонтально расположенными обрезиненными роликами 12. Над ситом 10 установлена подпружиненная пружинами 13 . лопатка 14,которая с помощью шарниров 15 закреплена к днищу 9 приемного бункера 1. Лопатка 14 выполнена в виде дугообразной перфорированной обрезиненной стальной пластины, обращенной выпуклой стороной к ситу 10.3. The latter is installed in the cabin 4 minders. The shaft 5 of the feeder screw is connected by a V-belt drive with an electric drive 8. In the bottom 9 of the receiving hopper 1, a sieve 10 is mounted above the entrance to the reloader 2. On the pallet. 5, the posts 11 are fixed with horizontally located rubberized rollers 12. Above the sieve 10, spring-loaded springs 13 are installed. a blade 14, which is secured by hinges 15 to the bottom 9 of the receiving hopper 1. The blade 14 is made in the form of an arcuate perforated rubberized steel plate, convex facing the sit 10.

Штукатурная установка работает следующим образом.Plaster installation works as follows.

Загрузив в приемный бункер 1 штукатурный раствор, включают электропривод 8, который приводит во вращение вал 5 со шнеком-питателем 6. При этом шнек-питатель 6 перемещает раствор по направлению стрелки Д (фиг.1) к ситу 10. Ролики 12, вращаемые по траектории окружности Д, прокатываются по лопатке 14, заставляя последнюю прижиматься к ситуHaving loaded the plaster mortar into the receiving hopper 1, turn on the electric drive 8, which drives the shaft 5 with the screw feeder 6. In this case, the screw feeder 6 moves the solution in the direction of the arrow D (Fig. 1) to the sit 10. Rollers 12 rotated along the trajectories of the circle D are rolled along the blade 14, forcing the latter to cling to the sit

Claims

I The invention relates to construction and is intended for the mechanization of finishing work, but is advantageous for receiving, mixing and transporting plaster to work places. A plasterer is known for having a sieve receiving hopper, a loading crane and a flj mortar pump. However, this installation has a low productivity due to the small volume of the receiving bunker. With an increase in the volume of the receiving hopper, the solution does not flow well to the material handler. Closest to the proposed one, there is a plaste installation, which includes a cabin, a receiving hopper with a tractor screw and a sieve built into its bottom, a loading crane and a mortar pump 2. The disadvantage of this setup is low productivity. The purpose of the invention is to increase productivity and improve working conditions. The goal is achieved by the fact that in a plastering installation, including a cabin, a receiving bunker with a feeder screw and a sieve embedded in its bottom, a loading device and a mortar pump, the receiving bunker is provided inside with an arc-shaped blade, with the convex side facing to the sieve, spring-loaded at one end, l the other is pivotally connected. with the bottom of the hopper, the shaft of the auger-feeder is equipped with racks with horizontally located rollers interacting with the blade, the blade being made perforated. Fig. I shows a plaste installation, top view; in Fig.2 a section aa in Fig.1; on fig.Z - view B in figure 2. The plasterer installation consists of a receiving bunker 1 connected by a loader 2c with a mortar pump 3. The latter is installed in the cab. 4 minders. The shaft 5 of the auger-feeder 6 is connected by a clinoremea gear 7 with an electric drive 8. In the bottom 9 of the foot bunker 1, a sieve 10 is mounted above the entrance to the conveyor 2. On the shaft 5 there are fixed racks 11 with horizontal rubber rollers 12 installed. 14, which with the help of hinges 15 is fixed to the bottom 9 of the receiving hopper 1. The blade 14 is made in the form of an arc-shaped perforated cut steel plate, with the convex side facing the sieve 10. The plasteur installation works as follows m Having loaded into the receiving hopper 1 piece solution, turn on the electric drive 8, which causes the rotation of the shaft 5 with the feeder screw 6. At the same time, the screw feeder 6 moves the solution in the direction of arrow D 1} to sieve 10. Rollers 12, rotated along the trajectory circles D, Rolled along the blade 14, forcing the latter to press against the sieve 10. The spring 13 returns the blade 14 to its upper initial position. Thus, the blade 14 oscillates around the hinge 15, will force the solution into the material handling device 2, and the blade oscillations have constant periods of 344 and amplitude do Due to this, the solution enters the pipeline in equal portions irrespective of its quantity in the receiving bin. This makes it possible to significantly increase the productivity of the installation and fully develop the solution loaded into it. Claim 1. Plastering installation, including a cabin, a receiving bunker with auger and a sieve built into its bottom, a loading crane and a mortar pump, characterized in that, in order to increase productivity and improve working conditions, the receiving bunker is provided inside with an arcuate spatula facing convex The side to the CHTVi is spring-loaded at one end, and the other is pivotally connected to the bottom of the bunker, and the shaft of the auger-feeder is equipped with racks with horizontal rollers, interacting with a spatula. 2.
