Abstract

The utility model relates to an electromagnetic control of concrete proportioning machine unloads bin gate. It is composed of a movable door hinged on a pin shaft and capable of rotating around the pin shaft and two groups of hooks driven by electromagnets. One end of the movable door is a free end, and the other extending end is provided with a counterweight. Two groups of hooks are hinged on the fixed shaft and can horizontally swing, and the two groups of hooks are respectively matched with the free end of the discharge door and the hook pin on the counterweight end. Starting the first electromagnet, disengaging the first group of hooks from the free end of the bin gate, opening the bin gate, and hooking the counterweight end of the bin gate by the second hook; and starting the second electromagnet, separating the second hook from the counterweight end of the charging door, and closing the charging door under the action of counterweight gravity.

Description

Electromagnetic control discharging gate for concrete proportioning machine

The utility model belongs to building machinery, is a kind of Electromagnetic Control device for discharging of concrete proportioning machine.

The device for discharging of existing concrete proportioning machine mainly contains two kinds of forms: a kind of is the belt conveying-type, and another kind is a gate-type.The exit Wu Men of the former discharge hopper, but utilize the bottom surface of conveying belt as discharge hopper, travelling belt is motionless during batching, and the back of having prepared burden starts travelling belt, and material is sent.This device for discharging volume is big, take more space, and manufacturing expense is higher, the conveying belt rapid wear.The latter adopts gear train such as worm and gear to drive Dump gate more, and its structure is complicated, and manufacturing cost is also higher, and because the environment of working-yard is more abominable, its failure rate is higher.

The purpose of this utility model provides a kind of simple in structure, safe and reliable, but and the Electromagnetic Control Dump gate of the concrete proportioning machine of quickly discharging material.

Solution of the present utility model is: the Electromagnetic Control Dump gate of the concrete proportioning machine that is provided comprises a movable bin gate that is hinged on the discharge hopper exit and can rotates around hinging pin shaft by bearing pin, is provided with the bin gate counterweight that is fixed together with movable bin gate body at the opposite side of aforementioned bearing pin.In addition, also be provided with two groups by solenoid actuated and can be around the hook of dead axle horizontal hunting, wherein the position of first group of hook is that this hook can hook hook pin on the bin gate free end when bin gate is closed; The position of second group of hook is to open aft hook when bin gate can hook hook pin on the bin gate counterweight end.When proportioning machine in the batch weighing process, Dump gate is closed.Weighing finishes, first group of electromagnet energising action, and it is linked up with horizontal hunting and breaks off relations, because the action of gravity of the material in the discharge hopper is opened bin gate, material drops out from hopper rapidly.When bin gate was opened, the counterweight end of bin gate forwarded second group of hook place to bin gate, was linked up with and hooked.Discharging finishes, and starts second group of electromagnet the counterweight end is broken off relations, and bin gate resets and closes under the action of gravity of counterweight.

Compared with prior art, the utility model has the advantages that; Simple in structure, easy to maintenance, bin gate is opened rapidly.Because transmission link is few, so failure rate is extremely low.Because the open and close of bin gate is only by gravity, and electromagnet only need overcome the unhook resistance, so power consumption is less, and takies ground space hardly, its manufacturing expense is about 1/4 of belt conveying-type device for discharging.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Accompanying drawing is a concrete structure figure of the present utility model.

As shown in the figure: Dump gate 1 is made up of body 2 and base plate 3.One end of bin gate body 2 is hinged on discharge hopper 5 or the support by bearing pin 4, and the other end is a free end, and its both sides respectively are provided with a hook pin 6.The elongated end of bin gate base plate 3 is provided with counterweight 8 and hook pin 7.Be fixedly connected with of the front of only drawing among two electromagnet 9(figure in hopper 5 outsides and the corresponding position of bin gate free end), each electromagnet respectively drives a hook 10, hook 10 is the connecting lever shape, is hinged on the bearing pin 11, and hopper 5 and 10 of hooks are provided with back-moving spring 12.Also be fixedly connected with an electromagnet 13 in another outside of hopper 5 and by the hook 15 on the bearing pin 14 of being hinged on of its driving.Bin gate 1 is hooked and closes by hook 10 during batching.Electromagnet 9 energisings during discharging, hook 10 is put to the right and is broken away from hook pin 6, promptly breaks off relations, and bin gate 1 is subjected to the action of gravity of material and rotates, opens around bearing pin 4.State after bin gate 1 is opened is shown in dot-and-dash line among the figure, and this moment, bin gate counterweight end turned to the top thereupon.Because hook 15 is hinged on the bearing pin 14, so can being hung in automatically, the hook pin 7 of bin gate counterweight end links up with on 15, the opening locking of bin gate 1.When closing bin gate, electromagnet 13 energisings, hook 15 is thrown off with bearing pin 7, and under the action of gravity of counterweight 8, bin gate 1 is closed, and by hook 10 lockings.

The utility model also can be used for the discharging of concrete mixer.

Claims

1, a kind of Electromagnetic Control Dump gate of concrete proportioning machine, it is characterized in that comprising a movable bin gate (1) that is hinged on discharge hopper (5) exit and can rotates around hinging pin shaft (4) by bearing pin (4), opposite side at aforementioned bearing pin (4) is provided with the bin gate counterweight (8) that is fixed together with movable bin gate body (2), in addition, also be provided with two groups and drive by electromagnet (9,13) and can be around the hook (10,15) of dead axle horizontal hunting, wherein the position of first group of hook (10) be when bin gate (1) when closing this hook (10) can hook hook pin (6) on the bin gate free end; The position of second group of hook (15) is that this hook (15) can hook hook pin (7) on the bin gate counterweight end after bin gate (1) is opened.
