Abstract

The utility model discloses a hopper for a concrete mixer. The present widely used hopper is provided with a single hopper which can realize lifting and charging once; when the utility model is used, the hopper is added with a longitudinal isolating plate; so the hopper is divided into two independent semi-hoppers; the discharging hole of the one semi-hopper is added with a special quadratic door opening plate, and the material can be discharged after the finished discharging of the material of the other semi-hopper according to the need; thereby, the single hopper which is lifted once can realize the charging twice. The utility model is suitable for the reshaping of the various present widely used concrete mixing machines, and the new mixing technology of the concrete with quadratic charging can be widely popularized.

Description

Hopperfor concrete mixer

The utility model is a kind of loading hopper that is used for concrete mixer.

In building trade, can when reducing cement consumption, concrete intensity and quality have been improved again owing to adopt the secondary batching method to prepare concrete.Thereby be the direction of development.But present domestic widely used concrete mixer, it is reinforced or the bucket type of tumbling is reinforced no matter to climb bucket type, all can only be that monobucket once promotes once and feeds intake.Adopt the secondary batching method as desire, just material must be loaded and unloaded for twice, not only inconvenient, and also labor strength is big.Adapt with the secondary batching process, Japan once proposed a kind of double layer concrete agitating device, finished with rabbling mechanism by two covers are independently reinforced, and it is applicable to concrete a large amount of serialization production.Domesticly also once design a kind of concrete mixer that adopts the twin-bucket second lift to feed intake respectively, but must adopt two cover motors and gearbox to control respectively.Complex structure, energy consumption is big, is difficult for promoting the use of.

The purpose of this utility model is present monobucket once to be promoted the hopper that once feeds intake transform, and designs a kind of monobucket and once promotes the hopper that can realize secondary batching.

The utility model is once to promote in the loading hopper that once feeds intake at present a midfeather is set, and hopper is divided into half bucket with two independent volumes, can hold two kinds of materials respectively.Material when avoiding hopper discharge in two volumes draws off simultaneously, and the discharging opening places of one and half buckets are provided with the secondary plate that opens the door therein.When hopper by common mode in mixing drum when reinforced, the material that no secondary opens the door in half bucket of plate is drawn off for the first time, opens the secondary plate that opens the door again according to the needs that stir then, draws off the material in this half bucket, the purpose of realization secondary batching.For the hopper that is provided with the plate that once opens the door, as climb the bucket type hopper, secondary open the door discharging opening that plate can be located at this half bucket with once open the door between the plate, so just can not influence the process of the action and the discharging first time of the plate that once opens the door.The open the door keying of plate of secondary can take variety of way to control, and for example can realize by systems such as manual or automated hydraulic pressure or electric power push rods.

As an embodiment of the utility model concrete structure as shown in drawings.

What present embodiment was given is to adopt to climb the reinforced hopper of bucket shape formula.In present widely used monobucket once promotes the concrete mixer hopper (1) that once feeds intake, establish a midfeather (2), hopper (1) is separated into two independently half buckets.Because hopper (1) itself has had the plate (4) that once opens the door, the plate so secondary opens the door (3) is located at the discharging opening of one of them half bucket and once opens the door between the plate (4).The secondary plate (3) that opens the door pins by hook (5) when closing.The gravity of material acts on the hook (5) by the secondary plate (3) that opens the door in the hopper, and hook (5) is an integral body with linkage (7), and the leverage that is produced by hinge (8) transfers the pressure to and is subjected to last item (9).But since be subjected to last item (9) be in the connecting rod minor details axially with the equitant dead-centre position of pressure direction of transfer on and held out against, can not unclamp and be in locking state so link up with (5).When hopper (1) when rail bracket (12) rise to arrive the lift stroke terminal point and carries out discharging, the plate (4) that once opens the door is opened by common mode, the material that no secondary opens the door in half bucket of plate is discharged in the mixing drum, and the plate but secondary opens the door (3) is not still opened by hook (5) locking.When hopper (1) arrives the lift stroke terminal point, also touched the switch of the time relay that is located at the trip destination county, make its timing of starting working.The time relay here can be selected any time relay commonly used for use.According to the time requirement of adjusting in advance, the time relay then will send signal, by manually or by control hydraulicdriven press mechanism (10) automatically, pushing downwards is subjected to last item (9), make it break away from the dead-centre position, by the leverage of linkage (7), hook (5) is thrown off the secondary plate (3) that opens the door, the secondary plate (3) that opens the door is opened downwards around hinge (6), draws off the material in this half bucket.Because first and second plate that opens the door is to open to equidirectional around common hinge, and the plate (4) that once opens the door is in the open the door below of plate (3) of secondary, therefore the hopper (1) after the discharging is descending along rail bracket (12), once open the door plate (4) when process is closed routinely, and the plate (3) that also just secondary opened the door is simultaneously closed.When hopper (1) when continuing to come downwards near stroke end, the reseting baffle (11) that is located at rail bracket (12) lower end will upwards be boosted by last item (9) to make it get back to the dead-centre position heavily again, and hook (5) has just recovered initial locking state again.

Hopper of the present utility model is once to promote the hopper that once feeds intake take now widely used monobucket to design as the basis, mainly transform at hopper, remainder has all kept existing structure, and improved hopper and control system thereof is simple in structure, convenient maintenance, cost is low, is well suited for present various concrete mixers are transformed, and is conducive to promote as early as possible the advanced technologies method of secondary batching. Compare with the mechanism of twin-bucket second lift, not only do not need two cover motor and gearboxes, reduced energy consumption, and the workman need only carry out the loading and unloading of a material, also reduce workman's labour intensity.

Claims (2)

1, a kind of loading hopper of concrete mixer, it is characterized in that having in the hopper (1) longitudinal baffle (2) that hopper is divided into half bucket with two separate volumes, the discharge port places of one and half buckets are provided with material draws off in this half bucket of control the secondary plate (3) that opens the door therein.

2,, it is characterized in that said secondary opens the door plate (3) by time relay control unlatching as the sharp 1 described loading hopper that requires.
