And a vibration motor is arranged on the side wall of the first charging barrel.
Compared with the prior art, the utility model discloses following outstanding beneficial effect has:
1. the pouring speed can be considered at the same time through a first-speed and second-speed discharging mode, and the later operation is facilitated;
2. can reduce the air that gets into the concrete through vibrating motor and stirring wheel's combined action, and then reduce the quantity of concrete bank protection inside gas hole.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention is further described with reference to the drawings and the detailed description.
As shown in figure 1, the utility model comprises a first charging barrel 1 and a second charging barrel 3, wherein the first charging barrel 1 is arranged at the upper part, and the second charging barrel 3 is arranged at the lower part. The upper part of the first charging barrel 1 is of a cylindrical structure, and the lower part of the first charging barrel is of an inverted cone structure, so that a structure with a large upper part and a small lower part is formed. The lower extreme opening of a feed cylinder 1 is located No. two feed cylinders 3, and No. two feed cylinders 3 are seal structure.
The lower wall of the second charging barrel 3 is provided with an inverted cone-shaped discharge hole 6, the discharge hole 6 is internally provided with an inverted cone-shaped piston 5, and the upper part of the piston 5 is provided with a piston rod 2 fixedly connected with the piston. The piston rod 2 penetrates through the upper wall of the second charging barrel 3, and the piston rod 2 is connected with the upper wall of the second charging barrel 3 in a sealing mode. The fixed discharging pipe 7 that is equipped with in 6 outer ends of discharge gate, the end of discharging pipe 7 is equipped with handle 8, discharging pipe 7 be soft tubular structure, handle 8 is stereoplasm tubular structure.
The lateral wall of a charging barrel 1 on be equipped with vibrating motor 13, can increase the mobility of concrete in a charging barrel 1 through vibrating motor 13's vibration effect, promote air escape and float 3 come-up. And a stirring wheel 12 is arranged in the second charging barrel 3 and below the first charging barrel 1. The fluidity of concrete in the first charging barrel 1 can be increased by the stirring action of the stirring wheel 12, and air discharge is promoted. The air that gets into the mould when can reduce concrete placement through twice exhaust has avoided the structural strength of concrete bank protection to receive the influence.
A cross beam 10 is arranged below the two charging buckets, one end of the cross beam 10 is hinged with a fixed structure, and the fixed structure can be a ground or a base and the like. A spring 11 is arranged below the cross beam 10. A pull rod 4 is arranged above the cross beam 10, and two ends of the pull rod 4 are respectively hinged with the cross beam 10 and the upper end of the piston rod 2. The beam 10 is used for placing a mould.
The operation flow is as follows: when carrying out the pouring of concrete bank protection, at first pour into a proper amount concrete into feed cylinder 1 in, can realize reinforced to the internal fixed quantity of feed cylinder 1 in modes such as mark through the interior mark scale of feed cylinder 1. Discharge gate 6 exposes great gap at the beginning, can realize arranging fast and arrange the material. Along with the progress of arranging the material process, mould weight increases, pushes down crossbeam 10, drives the piston through pull rod 4 and piston rod 2 and descends, and the gap of discharge gate 6 reduces, arranges the material speed and slows down. Thereby being convenient for later operation. The material discharging mode of firstly fast and then slow can not only take pouring speed into consideration, but also facilitate later operation. The combined action of the vibrating motor 13 and the stirring wheel 12 can reduce the air entering the concrete, thereby reducing the number of air holes in the concrete slope protection.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
