Detailed Description

As shown, the present embodiment includes a base 1, and a set of wheels 12 are mounted on the bottom of the base 1 for facilitating movement of the present embodiment to a suitable work site. A push handle 2 is arranged on one side of the base 1.

The base 1 of the present embodiment is provided with a stirrer 13, and the stirrer 13 includes a stirring portion in an upper portion thereof and a cavity in a lower portion thereof, and a driving portion provided in the cavity: the stirring part comprises a stirring barrel thereof, a stirring shaft arranged therein and a stirring rod 16 on the stirring shaft 15, and an openable cover plate 3 is arranged at the upper opening of the stirring barrel. The stirring shaft 15 passes through the bottom plate of the stirring barrel and is connected with the driving part. The perforation is provided with a sealing gasket 22 and a bearing 23. The driving portion of this embodiment includes a motor 17 and a pair of intermeshing bevel gears connected to the motor 17, with driven wheels connected to the agitator shaft 15.

A discharging pipe is arranged at one side of the bottom of the stirring barrel, and an electromagnetic valve 21 for controlling the opening and closing of the discharging pipe is arranged at the discharging pipe.

A positioning barrel 10 is arranged on one side of the stirrer 13, the positioning barrel 10 is arranged on a supporting plate 20, and the supporting plate 20 is arranged on the base 1 through a group of supporting springs 18. A key 19 is arranged between the supporting plate 20 and the base 1. To prevent the external environment from polluting the keys 19 of the supporting springs 18, the periphery of the supporting plate of the embodiment is folded downwards to cover the corresponding base 1.

The key 19 of this embodiment includes a cap 28 and an insulating base 30, wherein the insulating base 30 is provided with a guide cylinder having an inner flange at an upper end, the cap 28 is provided with a corresponding outer flange and the inner flange of the guide cylinder is engaged, a spring is provided between the cap 28 and a bottom surface of the guide cylinder, and after the cap 28 is pressed down, the cap moves downward along the guide cylinder, and when the pressure is reduced or disappears, the cap 28 is under the spring 29. A cap proximity switch 24 is provided on the outer flange of the cap 28, and a first closing proximity switch, an opening proximity switch and a second closing proximity switch are provided on the inner wall of the guide cylinder from top to bottom, respectively, and these proximity switches are electrically connected with the solenoid valve 21. The close switch on the guide cylinder is matched with the cap body close switch 24 to realize the opening and closing of the electromagnetic valve 21, so that the output of materials is realized or the output is stopped.

Two grooves 31 are symmetrically arranged on the inner surface of the positioning barrel 10 along the axis of the positioning barrel 10, holes which are communicated with the outer surface of the positioning barrel 10 are arranged at the lower bottoms of the two grooves 31, two positioning barrel ear hole seats 32 are correspondingly arranged on the outer surface of the positioning barrel 10, and holes are respectively arranged on the two positioning barrel ear hole seats. A lower roll 11 is also provided on one side of the positioning cylinder 10. Two guide ropes 4 respectively pass through holes of two positioning cylinder ear hole seats 32 and holes on the positioning cylinder 10 from a lower roller in sequence, pass through the positioning cylinder 10 upwards from a groove 31, and the other end of the guide ropes is connected to the workbench 6.

A working hole for receiving materials is arranged in the middle of the workbench 6, and two sides of the workbench are provided with upper winding rollers 9 through brackets 8. The guide rope 4 is fixed at the inner side of the bracket 8 through the working hole.

The winding roller 9 is connected to the lift cord 7. The lower end of the lifting rope 7 is connected with the feeding barrel 5 and is used for lifting the feeding barrel 7 to the workbench 6. Two sides of the feeding barrel 7 are respectively provided with a feeding barrel earhole seat 14, earholes are respectively arranged on the feeding barrel earhole seats, and two guide ropes 4 respectively pass through the earhole seats to guide the moving direction of the feeding barrel 7.

The positioning seat 10 of the present embodiment is configured to cooperate with the feeding barrel 7. When the feeding barrel 7 is not matched with the feeding barrel, the supporting plate 20 is unloaded, the cap 18 of the key 19 is positioned at the uppermost end of the guide barrel, and the key proximity switch 24 is matched with the first closing proximity switch in the guide barrel, so that the discharge port is in a closed state, and materials in the stirrer 13 cannot flow out.

After the feeding barrel 7 descends to the inside of the positioning seat 10 along the guide rope 4, under the action of the self weight of the feeding barrel 7, the cap 28 moves downwards to enable the cap proximity switch 24 to move to the position where the proximity switch is opened, the electromagnetic switch 21 is opened, materials are sent out to the feeding barrel 7, the cap 28 moves downwards further along with the increase and the weight increase of the materials in the barrel, and after the materials in the feeding barrel reach a certain weight, the cap proximity switch 24 is matched with the second closing proximity switch to enable the discharge port to be closed, and at the moment, the feeding barrel 7 can be pulled to move upwards through the winding roller. In the process, although the discharging pipe can be started to be opened again, less material is sent out in the process, and the first closing proximity switch is started again to close the feeding pipe after the material is moved upwards again, so that misoperation cannot occur.

According to the structure, under the condition that materials are stirred in advance, the feeding process of the feeding barrel can be automatically completed by operating the feeding barrel 7, so that one-man operation is easy to realize.
