Description

Technical Field

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is mainly composed of cementitious materials, aggregates, water, admixtures and additives in a certain proportion. It is an artificial stone made by uniform mixing, dense molding, curing and hardening. It has the characteristics of abundant raw materials, low price and simple production process.

[0003] At the concrete production site, large quantities of concrete need to be transported quickly by conveying mechanisms to avoid long-term accumulation and solidification problems. There are currently two common concrete conveying mechanisms on the market. One is the belt type, in which concrete is transported by a conveyor belt. It is low in cost, but the concrete itself is in a relatively static state and has a slight solidification phenomenon after long-distance transportation. The other is the screw conveyor, which is transported by a screw conveyor shaft and mixed simultaneously during the transportation process. The cost is relatively high, and there are still some functional deficiencies in actual use. There is room for improvement. For example, the height of the equipment is fixed and cannot be fine-tuned according to the terrain of the site or the height of the supporting equipment. There are certain limitations in use, and it does not have the function of facilitating the adjustment of the equipment height. Utility Model Content

[0026] The front and rear ends of the supporting beam 2 are respectively flush with the front and rear ends of the "U"-shaped feeding trough 1. The end of the adjusting cylinder 3 near the "U"-shaped feeding trough 1 is connected to the "U"-shaped feeding trough 1. The inner diameter of the adjusting cylinder 3 is adapted to the outer diameter of the supporting leg 4. The adjusting cylinder 3 can slide up and down along the outside of the supporting leg 4. The bottom of the end of the adjusting cylinder 3 near the "U"-shaped feeding trough 1 is provided with an electric cylinder reserved groove 6. The top of the large thrust electric cylinder 5 is connected to the top of the inside of the adjusting cylinder 3, and the height of the equipment can be slightly adjusted.

[0027] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the large thrust electric cylinder 5 in the supporting leg 4 is started, and the large thrust electric cylinder 5 extends upward or retracts, which can drive the adjusting cylinder 3 to move up and down along the outside of the supporting leg 4. The "H"-shaped structure formed by the adjusting cylinder 3 and the supporting beam 2 can support the "U"-shaped feeding trough 1, so that its actual height changes. The electric cylinder reserved groove 6 reserves space for the external motor part of the large thrust electric cylinder 5, and the ground fixing plate 7 is mainly used for docking with the ground or the lower bracket.

[0028] Embodiment 2: Multiple groups of positioning bolt rods 11 are welded to the front and rear ends of the top of the “U”-shaped feed trough 1, and the outside of the positioning bolt rod 11 is sleeved with a fixing nut 12. Four groups of mounting plates 9 are horizontally placed at the front and rear ends of the top of the “U”-shaped feed trough 1, and multiple groups of positioning eyes 10 are arranged inside the mounting plates 9. Five groups of longitudinal reinforcement bars 13 are welded between the tops of the two groups of mounting plates 9, and three groups of transverse reinforcement bars 14 are transversely welded to the tops of the longitudinal reinforcement bars 13.

Vibration can reduce the adhesion of concrete materials to the wall, thereby reducing the difficulty of later cleaning.

[0031] Specifically, Figure 1 and Figure 6 As shown, the vibration motor 20 in the shell 19 starts regularly and generates vibration, and the vibration is transmitted to the "U"-shaped feeding trough 1, causing the inner wall of the "U"-shaped feeding trough 1 to vibrate continuously with a small amplitude, which can shake off the concrete material attached thereto and prevent it from adhering to its inner wall. The motor wiring port 21 is convenient for wiring to power the vibration motor 20.

[0032] Working principle: When the utility model is in use, first, the mixed concrete material is introduced into the feed hopper 8, and the concrete material flows into the "U"-shaped feeding trough 1 along the feed hopper 8. The driving motor 16 drives the spiral feeding shaft 22 to rotate continuously through the reducer 15, and the concrete material under the feed hopper 8 is transported to the discharge port 18, and falls from the discharge port 18 to the secondary conveying equipment below. During the transportation process, the actual height of the "U"-shaped feeding trough 1 can be adjusted according to the actual needs of the production site and the height of the supporting equipment. The large thrust electric cylinder 5 in the supporting leg 4 is started, and the large thrust electric cylinder 5 extends upward or retracts, which can drive the adjustment cylinder 3 to move up and down along the outside of the supporting leg 4. The "H"-shaped structure formed by the adjustment cylinder 3 and the supporting beam 2 can support the "U"-shaped feeding trough 1, so that its actual height changes. The electric cylinder reserved slot 6 reserves space for the external motor part of the large thrust electric cylinder 5, and the ground fixing plate 7 is mainly used for docking with the ground or the lower bracket. Before conveying concrete materials, safety protection should be done in the opening area at the top of the "U"-shaped feeding trough 1. The longitudinal reinforcement bars 13 and the transverse reinforcement bars 14 form a set of protective cages. The positioning eyes 10 on the mounting plate 9 at the bottom of the cage are aligned with the positioning bolt rods 11 at the top of the "U"-shaped feeding trough 1 and inserted. Then, the fixing nuts 12 are inserted into the top of the positioning bolt rods 11 to complete the installation. The protective cages formed by the longitudinal reinforcement bars 13 and the transverse reinforcement bars 14 can form protection to prevent personnel from directly contacting the spiral feeding shaft 22 and causing safety accidents. When disassembling and cleaning in the later stage, the fixing nuts 12 can be directly removed and the protective cages can be directly removed. The spiral feeding shaft 22 rotates continuously to transport the concrete material under the feed hopper 8 to the discharge port 18. During the transportation process, the vibration motor 20 in the shell 19 starts regularly and generates vibration. The vibration is transmitted to the "U"-shaped feeding trough 1, causing the inner wall of the "U"-shaped feeding trough 1 to vibrate continuously with a small amplitude, which can shake off the concrete material attached thereto and prevent it from adhering to its inner wall. The motor wiring port 21 is convenient for wiring to power the vibration motor 20.
