Abstract

A pneumatic bin-distribution mechanism belongs to pneumatic blanking control devices used together with bulk feed trucks. A movable valve is fixed at the outer end of a piston rod of a cylinder whichtakes compressed air of an automobile air holder as the working air source; when the piston rod is positioned at the top stroke dead center, the lower edge of the movable valve is attached to the wallof a stock bin, thereby shutting the blanking channel; when the piston rod runs upward, the blanking channel is opened gradually; a cylinder cover is covered on the cylinder; and a pressure reductionplate is fixed at the lower part of the cylinder cover. The utility model has the characteristics of simple and compact structure, no pollution and reliable blanking control.

Description

Pneumatic minute storehouse mechanism

Technical field

The utility model relates to the blanking control mechanism of solid grain and powder, especially for the blanking pneumatic control mechanism of the feed of bulk fodder transport truck.

Background technology

The bulk feed car has multiple advantage with respect to existing packed feed mode, and for example, one can be saved a large number of Packing Fee (fee of material and packing and the labour cost of unpacking); Its two, can reduce traffic cost (having saved the transportation of external packing); Its three, stopped packed feed mode in transportation, the loss of loading and unloading link bale broken and make disadvantage at food pollution; Its four, be not easy to realize automatic discharging.

The general bottom of existing bulk fodder transport truck be a spiral conveying mechanism, and this mechanism can not separate discharging to material (feed) in each storehouse, and the per car material can't transport several different materials (feed) simultaneously, thereby causes the misuse of transport facilities.

Need to design a kind of blanking control setup in last every feed bin of transport trolley, if adopt the fully mechanical structure, its control structure part can be complicated, is difficult for Operation and maintenance.

The utility model content

The purpose of this utility model provides a kind of existing pressurized air of automobile of utilizing and is power, pollution-free, simple in structure, pneumatic minute storehouse mechanism of control failure-free.

This later-model purpose is achieved in that a kind of pneumatic minute storehouse mechanism, be fixed with a movable valve with automobile gas tank pressurized air as the piston rod outer end of cylinder of work source of the gas, when piston rod is positioned at the down stroke stop, the lower edge and the bin wall of movable valve fit, thereby close blanking channel, when piston rod is up, open blanking channel gradually; Be covered with cylinder cover on the cylinder, the cylinder cover bottom is fixed with the decompression plate.

Check before reinforced: when the air pressure of the source of the gas treater in the control box reaches 0.7Mpa, handle feed bin pneumatic door operating handle, (whether the open and close of feed bin pneumatic door are flexible to make the continuous opening and closing of feed bin pneumatic door check branch storehouse mechanism, whether gas-tpe fitting leaks gas, and tracheae has or not breakage etc.) work whether normal; Confirm working properly after, can carry out following operation.

According to local feed kind, proportion, flowing power, the fixed decompression regulating plate of minute storehouse mechanism is carried out the gap adjust.Pneumatic minute storehouse mechanism fixed decompression sheet separation (straight-line distance that refers to fixed decompression plate lower end and tank body swash plate) adjustment reference value is divided into two kinds in the tank body: the decompression sheet separation of 1, unloading pellet: 30～70mm; 2, unload the decompression sheet separation of mash feed: 60～100mm; The feed semitrailer is adjusted (particulate material Φ 3 * 5) by Chinese forage standard when dispatching from the factory.

Feed bin is reinforced: add feed in feed bin before, each feed bin pneumatic door should be in closed condition (check whether the feed bin pneumatic door closes fully, can feed in raw material) after confirming to have closed, should make in each feed bin feed as far as possible evenly when reinforced; After reinforced the finishing, the reinforced door closure of feed bin must be closed tight and with fixedly self-locking of cuff link, to prevent that door closure slips off and avoid entering of rainwater and other foreign material automatically in the transportation.Pay special attention to when reinforced: never allow to sneak into wooden unit, iron block, stone and other foreign material in the feed, in order to avoid cause equipment damage.

This later-model beneficial effect is:

1, adopting existing compressed air units in cars is propulsion source, need not increase propulsion source.

2, simple for structure reasonable, blanking control is reliable.

3, easy to maintenance, easy to use, operational throughput may command.

4, every storehouse material of different size of all can packing into is independent of each other.

5, operate steadily, reliability is high.

6, manufacturing is simple, cost is low.

7, utilize pressurized air to be source of the gas, can not cause food pollution.

Description of drawings

Fig. 2 is the left view of Fig. 1-1;

Fig. 3 is this later-model pneumatic schematic diagram.

The specific embodiment

Fig. 1 illustrates, this is novel to be fixed with a movable valve 5 with automobile gas tank pressurized air as the piston rod outer end of cylinder 2 (cylinder supports frame 7 is arranged among the figure) of work source of the gas, when piston rod is positioned at the down stroke stop, the lower edge and the bin wall of movable valve fit, thereby close blanking channel, when piston rod is up, open blanking channel gradually; Be covered with cylinder cover 1 on the cylinder, the cylinder cover bottom is fixed with decompression plate 3.Through bolt decompression regulating plate 4 is arranged on the decompression plate 3, be arranged in the feed bin by the auger loader 9 of fluid motor-driven.

Principle of work:

Door opening state: when the material in the feed bin is carried, move by the air-channel system control cylinder, the feed bin pneumatic door is upwards lifted, at this moment, the material in former B zone then can flow to the a-quadrant, and the material of a-quadrant then can flow to the screw feeder delivery system, by screw feeder with mass transport to appointment place, so circulation then can realize the conveying of material.

Close a state: feed bin is being carried out when filling with substance, feed bin foot (branch storehouse mechanism part just) also has material and enters, material enters the B zone from the gap L between fixed decompression plate and the bin wall 6, this moment, material began from the B zone earlier to fill (a-quadrant is no material district), from bottom to up until whole feed bin is filled material.

The operational throughput of material can be controlled by the gap of adjusting fixed decompression plate regulating plate and bin wall.

Fig. 2 illustrates, and by median septum 8 it is separated between storehouse and the storehouse, and branch storehouse mechanism also is separate in each storehouse, and mechanism is controlled by cylinder, and the cylinder in a storehouse of a manual rotary valve control, thereby can pack into the material of different size of each storehouse are independent of each other.

Fig. 3 illustrates, and 5 pneumatic minute storehouse mechanisms carry out control operation by manual rotary valve 12 respectively.

Have among Fig. 3: 10, automobile gas tank; 11, rice font cylinder; 12, hand rotary valve; 13, magnetic valve; 14, Air-source treater.
