Problems solved by technology

[0004] However, during the use of the lower hopper, since there is a large amount of unsolidified concrete material in the lower hopper, due to the high viscosity of the concrete material, the concrete material is easy to adhere to the lower hopper (mainly concentrated at the lower end of the lower hopper) Inner wall), not only will increase the unprovoked loss rate of the concrete material, but also the concrete material will condense too much in the lower hopper, which will affect the normal use of the entire lower hopper, so a new technical solution needs to be proposed to solve the above problems

Embodiment 1

[0039] Example 1: A lower hopper for pouring, such as figure 1 As shown, it includes a hopper body 1 with open upper and lower ends and a hollow inside. The lower hopper body 1 is shaped like a polygonal pyramid with a wide upper and a narrow lower. The lower end of the hopper body 1 is horizontally provided with a clamping slot 3 on the outer wall of the side close to the discharge opening 2. The outer wall of the clamping slot 3 is hinged with a cover 5 for opening and closing the discharge opening 2 through a rotating shaft 4, the cover 5 The first handle 6 is provided on it. The operator uses the first handle 6 to drive the cover 5 to rotate around the rotating shaft 4 to the outside of the slot 3. At this time, the blanking opening 2 is opened, thus completing the work of blanking and pouring concrete.

[0040] Such as figure 1 with figure 2 As shown, in order to save effort when opening and closing the cover 5, a second handle 18 is provided on the outer wall of the lower ...

Embodiment 2

[0045] Example 2: A lower hopper for pouring, which is different from Example 1 in: image 3 with Figure 4 As shown, in order to reduce the linkage effect of the rotation of the propeller 7 on the cover 5 under other conditions, a circular hole 26 is provided on the nut 16, and a cylindrical guide rod 27 is connected to the circular hole 26 to move up and down. The rod 27 is arranged vertically, and a blocking block 28 is provided on the side close to the cover 5, such as Figure 4 with 5 As shown, an arc-shaped sliding groove 29 is opened on the upper end surface of the cover body 5, and the slider 14 slides to be connected in the sliding groove 29. In addition, a motor 19 is fixed on the outer wall of the hopper body 1, and a protective shell (not shown in the figure) is installed outside the motor 19, which can reduce the possibility of the motor 19 being splashed by the concrete material and protect it. The function of the motor 19, and the above-mentioned rotating shaft 8 ...

Embodiment 3

[0046] Embodiment 3: A lower hopper for pouring. The difference from embodiment 1 is that in order to facilitate the forklift to carry and lift the lower hopper body 1, four through holes 21 are provided on the hopper body 1 opposite to each other. The crossbars can be inserted into the two opposite through holes 21 respectively, so that the functions of transporting and lifting the lower hopper body 1 can be achieved, which is very convenient.

Abstract

The invention discloses a discharging hopper used for pouring and belongs to the technical field of building construction equipment. According to the technical scheme, the discharging hopper comprisesa hopper body, openings are formed in the upper and lower ends of the hopper body correspondingly, and the interior of the hopper body is hollow; a clamping groove is formed in the outer wall of theside, close to a discharging outlet, of the lower end of the hopper body; a cover used for opening and closing the discharging outlet is hinged to the outer wall of the clamping groove through a rotary shaft; a first handle is arranged on the cover; at least one propeller is rotationally connected into the discharging hopper body, and a rotary shaft of the propeller stretches out of the hopper body; and a driving assembly used for driving the propeller to perform stirring is arranged and comprises a first bevel gear coaxially connected to the free end of the rotary shaft and a second bevel gear engaged with the first bevel gear, and the second bevel gear is connected to the end, away from the discharging outlet, of the rotary shaft; and a second gear is arranged fixedly at the lower end ofthe cover, and the lower end of the rotary shaft is provided with a first gear engaged with the second gear. According to the discharging hopper used for pouring, setting of concrete materials in thedischarging hopper is retarded, the gratuitous loss rate of the concrete materials is decreased, a protecting effect on the discharging hopper is improved, and the service life of the discharging hopper is prolonged.

Description

Technical field [0001] The invention belongs to the technical field of building construction equipment, and more specifically, it relates to a lower hopper for pouring. Background technique [0002] The lower hopper for pouring is a commonly used pouring equipment in the field of construction, and its main function is to facilitate the rapid and timely pouring of precast parts. [0003] The current lower hopper for pouring has a hopper body with open upper and lower ends and a hollow inside. The lower end of the hopper body is provided with a card slot on the outer wall of the side close to the discharge opening. The outer wall of the card slot is hinged with a rotating shaft for opening and closing the material. The cover body of the mouth is provided with a first handle. By driving the handle, the operator can enable the cover to rotate horizontally around the rotating shaft, and at this time, the discharging port can be opened or closed. [0004] However, during the use of the l...
