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] Embodiment 1: a kind of lower hopper for pouring, such as figure 1As shown, it includes a hopper body 1 with open upper and lower ends and a hollow interior, and the lower hopper body 1 is in the shape of a polygonal pyramid with a wide top and a narrow bottom. At the lower end of the hopper body 1, a draw-in groove 3 is horizontally provided on the outer wall of the side close to the discharge opening 2, and a cover body 5 for opening and closing the discharge opening 2 is hinged on the outer wall of the draw-in groove 3 through a rotating shaft 4. There is a first handle 6 on it. The operator drives the above-mentioned cover body 5 to rotate around the rotating shaft 4 to the outside of the slot 3 through the first handle 6, and at this time, the material discharge port 2 is opened, thereby completing the work of material discharge and pouring of concrete.

[0040] Such as figure 1 and figure 2 As shown, in order to save more effort when opening and closing the ab...

Embodiment 2

[0045] Embodiment 2: a kind of lower hopper for pouring, differs from embodiment 1 in that: as image 3 and Figure 4 As shown, in order to reduce the linkage effect of the rotation of the propeller 7 on the cover body 5 in other cases, a round hole 26 is provided on the nut 16, and a cylindrical guide rod 27 is connected up and down in the round hole 26. The above guide Bar 27 is vertically arranged, is provided with block 28 on the side close to cover body 5, as Figure 4 and 5 As shown, an arc-shaped sliding groove 29 is opened on the upper surface of the cover body 5 , and the above-mentioned 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 concrete materials and protect the motor 19. The role of the motor 19, while the above-mentioned rot...

Embodiment 3

[0046] Embodiment 3: A lower hopper for pouring. The difference from Embodiment 1 is that in order to facilitate the handling and lifting of the lower hopper body 1 by a forklift, four through-holes 21 arranged oppositely in pairs are provided on the hopper body 1. The crossbars can be plugged into the two oppositely arranged through holes 21 respectively, thus the function of carrying and lifting the lower hopper body 1 can be achieved, which is very convenient.

Abstract

The invention discloses a pouring hopper, which belongs to the technical field of building construction equipment. Its technical points include a hopper body with open upper and lower ends and a hollow interior. The outer wall of the draw-in groove is hinged with a cover body for opening and closing the discharge opening through a rotating shaft. The cover body is provided with a first handle, and at least one propeller is rotatably connected in the lower hopper body, and the rotation shaft of the propeller Protrude out of the hopper body and be provided with a drive assembly for driving the propeller to stir, the drive assembly includes a first bevel gear coaxially connected to the free end of the rotating shaft, a second bevel gear meshed with the first bevel gear, The second bevel gear is connected to the end of the rotating shaft away from the feeding port; the lower end of the cover body is fixed with a gear 2, and the lower end of the rotating shaft is provided with a gear 1 meshing with the second gear. The invention delays the coagulation of the concrete material in the lower hopper, reduces the unreasonable loss rate of the concrete material, improves the protection effect on the lower hopper, and prolongs its service life.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and more specifically 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 prefabricated parts. [0003] At present, the lower hopper for pouring is a hopper body with open upper and lower ends and a hollow interior. The lower end of the hopper body is provided with a card slot on the outer wall near the discharge port. The cover body of the mouth is provided with a first handle on the cover body. By driving the above-mentioned handle, the operator can make the cover body rotate horizontally around the rotating shaft, and at this time, the feeding opening can be opened or closed. [0004] However, during the use of the lower hopper, since there is a large amount of unsolidified concrete mate...
