Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to concrete conveying equipment. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, mixed with water in a certain proportion and stirred. It is also called ordinary concrete and is widely used in civil engineering.

[0003] After the concrete processing is completed, it is necessary to use a concrete transport cart to transport the processed concrete to the working position. The traditional transport cart has a simple structure. When the transport vehicle is pushed to the working position, the discharge port is opened by the baffle plate, and the stepper motor is powered on to drive the winding roller to rotate to reel the soft parts, and drive the movable seat to move up. During this process, the second plate body moves relative to the first plate body to adjust the angle between the bottom plate and the transport vehicle body. Under the meshing action between the gear and the rack, the gear drives the stirring roller to rotate synchronously during the upward movement of the movable seat, thereby stirring the concrete in the transport vehicle body to make it loose; however, during the long-term transfer of concrete, stratification and sedimentation are prone to occur. During a short dumping, the stirring roller can only stir the concrete in the bottom stratification, but cannot mix it evenly with the upper layer, which seriously affects the quality of the finished concrete after pouring. In addition, during the pouring process, only the pouring points can be poured one by one, and multi-point pouring work cannot be satisfied at the same time, which seriously restricts the efficiency of pouring.

During pouring, the concrete can be discharged synchronously from multiple points, and the discharge position can be independently controlled to quickly deliver it to the designated pouring point, thereby greatly improving the efficiency of pouring.

[0042] In one embodiment of the present invention, a feed pipe 3 is fixedly installed at the top of the feed box 1 for filling concrete into the cone 2; a frame 26 is symmetrically installed at the bottom of the feed box 1, and wheels 27 are rotatably arranged on the frame 26 to deliver concrete to a designated location as needed.

[0047] In one embodiment of the present invention, when in use, the stirred concrete is added into the cone 2 along the feed pipe 3, and the driving motor 6 is provided to drive the stirring shaft 4 to rotate along the feed box 1. On the one hand, the stirring shaft 4 drives the conveying blade 8 to rotate in the sleeve 7, and the concrete at the bottom moves upward along the sleeve 7. On the other hand, the stirring shaft 4 drives the transverse stirring rod 9 to rotate synchronously, and the multiple transverse stirring rods 9 are provided to stir the rising concrete to avoid precipitation of the concrete during movement, thereby ensuring that the concrete concentration of the upper and lower layers remains consistent.

[0048] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the discharge system 200 includes a feed cylinder 10, a transmission shaft 11, a second conveying blade 12 and a discharge pipe 13;

A conveying blade 2 12 is installed on the transmission shaft 11 and located inside the feeding cylinder 10 to realize the concrete outlet work;

[0051] In one embodiment of the present invention, the middle section of the discharge pipe 13 is a corrugated tube to facilitate its deformation and movement; the end of the discharge pipe 13 is provided with a tapered portion to ensure that the outlet diameter is smaller than the rest of the position, thereby achieving the effect of increasing the flow rate.

[0052] The number of the feeding cylinder 10 and the discharging pipe 13 can be adjusted as needed in actual use to facilitate pouring from multiple positions.

[0053] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the adaptive connection mechanism 300 includes a limit shaft 15, a bevel gear 1 16, a retaining ring 17, a multi-stage telescopic member 18, a connection rod 19 and a bevel gear 2 20;

[0054] The limit shaft 15 is slidably mounted on the bottom end of the stirring shaft 4 and rotates synchronously with the stirring shaft 4;

[0055] The bottom end of the limit shaft 15 is fixedly connected with a bevel gear 16, and the bevel gear 16 is also meshed with a bevel gear 20 installed at the bottom of the transmission shaft 11 during the rising process;

[0056] A retaining ring 17 is rotatably installed at the bottom end of the feed box 1, and a pair of multi-stage telescopic parts 18 are arranged on the bottom surface of the retaining ring 17. The working end of the multi-stage telescopic part 18 is fixedly connected to the bevel gear 16, and the fixed end of the multi-stage telescopic part 18 is also connected to the limit shaft 15 through a connecting rod 19 to facilitate lifting the bevel gear 16 in the rotating state.

[0057] In one example of the present invention, the stirring shaft 4 and the limiting shaft 15 can be connected by means of longitudinal strips or longitudinal grooves, so that the limiting shaft 15 and the bevel gear 16 can be driven to rotate synchronously during the rotation of the stirring shaft 4. The limiting shaft 15 also drives the connecting rod 19, the multi-stage telescopic member 18 and the retaining ring 17 to slide along the feed box 1 in turn to ensure the smooth rotation of the bevel gear 16. At the same time, when the multi-stage telescopic member 18 is working, the multi-stage telescopic member 18 pulls the bevel gear 16 to move upward, so that the bevel gear 16 is in a meshing state with the bevel gear 2 20, and can drive the bevel gear 2 20 and the transmission shaft 11 to rotate synchronously when the bevel gear 16 rotates.

[0058] like Figure 1 , Figure 5 and Figure 6 As shown, as another preferred embodiment of the present invention, the directional adjustment mechanism 400 includes a rotating base 21, an annular groove 22, a movable block 23 and a telescopic member 24;

[0061] In one example of the present invention, the movable block 23 is pulled by a stepper drive module installed in the annular groove 22. The stepper drive module includes a motor, a drive system, and a traveling wheel. Each movable block 23 can be driven independently so as to independently pull the discharge pipe 13 to twist horizontally through the telescopic member 24. The telescopic member 24 also slides along the guide groove 25, and when the telescopic member 24 works, it pulls the discharge pipe 13 to swing in the longitudinal plane along the end of the feed cylinder 10, so that the end of the discharge pipe 13 quickly reaches the casting position.

[0062] To summarize, the mixed concrete is added into the cone cylinder 2 along the feed pipe 3, and the driving motor 6 is provided to drive the stirring shaft 4 to rotate along the feed box 1. On the one hand, the stirring shaft 4 drives the conveying blade 8 to rotate in the sleeve 7, and the concrete at the bottom moves upward along the sleeve 7. On the other hand, the stirring shaft 4 drives the transverse stirring rod 9 to rotate synchronously, and the multiple transverse stirring rods 9 are provided to stir the rising concrete to prevent the concrete from settling during movement. During the rotation of the stirring shaft 4, the limiting shaft 15 and the bevel gear 16 are driven to rotate synchronously. The limiting shaft 15 also drives the connecting rod 19, the multi-stage telescopic member 18 and the retaining ring 17 to slide along the feed box 1 in turn to ensure the stability of the rotation of the bevel gear 16. At the same time, when the multi-stage telescopic member 18 is working, the multi-stage telescopic member 18 pulls the bevel gear 16 to move upward so that the bevel gear 16 is in meshing with the bevel gear 2 20. The conveying device can effectively prevent the concrete from settling inside the cone 2 during the conveying process, ensure the consistency of the concrete concentration, and ensure the quality of the concrete. In addition, the conveying device can also be used to discharge the concrete from the cone 2 to the concrete outlet 13, so that the concrete can be discharged from the cone 2 to the concrete outlet 13.
