TECHNICAL FIELD

[0001] The present application relates to the field of concrete production equipment, and particularly relates to a concrete production hopper. BACKGROUND

[0002] Concrete, referred to as "concrete" for short: refers to an engineering composite material prepared by mixing cement as a cementing material, sand and stone as aggregate, and water (which can contain additives and admixtures) in a certain proportion, and then stirring, and is widely used in civil engineering. In the concrete production system, the hopper as an important part connecting the concrete mixer and the transport tank truck directly affects the production efficiency of the whole production line.

The open hopper structure is simple and convenient to manufacture, but the concrete is easily affected by the outside during the discharging process, is polluted by rainwater and dust, and the quality of the concrete is affected. Although the closed hopper structure can avoid the pollution problem, the concrete is prone to blockage due to the air tightness of the closed structure, and it is difficult to dredge after blockage, which affects the conveying efficiency. Further, the existing concrete hopper is difficult to compatible with the concrete conveying efficiency and conveying quality. CONTENT OF THE INVENTION

[0030] The following will be described in detail with reference to the accompanying drawings. Figures 1-3 The application is further described in detail.

[0031] The application discloses a concrete production lower hopper.

[0032] Referring to Figure 1 , Figure 2 , the concrete production lower hopper comprises a hopper 1, a cover body 2, a vibration motor 3, a buffer support 4 and an adjusting mechanism 5, the control seat 6 is hingedly installed on the hopper 1 in the vertical direction, and the control seat 6 is hingedly installed on the discharge port of the concrete mixer in the horizontal direction; the cover body 2 is buckled on the opening side of the hopper 1, and the cover body 2 seals the upper opening of the hopper 1, and in the embodiment, the cover body 2 is an acrylic plate, which has the characteristics of high transparency, high toughness, good shock resistance and good impact resistance.

[0033] The worker aligns the hopper 1 with the feeding port of the transport tank truck, opens the valve of the discharge port of the concrete mixer, and then the mixed concrete can be conveyed into the concrete tank truck through the hopper 1, and in the conveying process, the cover body 2 seals the upper opening of the hopper 1, thereby reducing the pollution of rainwater and dust to the concrete.

[0034] Referring to Figure 1 , the control seat 6 is provided with a control piece 7, the control piece 7 is used for driving the control seat 6 to rotate, the control piece 7 comprises a control sleeve 71 and a control screw 72, the control sleeve 71 is hingedly installed on the control seat 6, and the control screw 72 is threadedly installed on the inner wall of the control sleeve 71, and the control screw 72 is hingedly connected with the concrete mixer.

[0035] The worker rotates the control screw 72, the control screw 72 drives the control sleeve 71 to move away from or close to the control screw 72, the control sleeve 71 can push the hopper 1, so that the hopper 1 drives the control seat 6 to rotate in the horizontal direction and is positioned at the current position after rotation, that is, the angle of the hopper 1 in the horizontal direction can be adjusted, so that the worker can align the hopper 1 with the feeding port of the transport tank truck, and the applicability of the hopper 1 to different unloading angles is improved.

[0036] Referring to Figure 1 , Figure 2The vibrating motor 3 is installed on the hopper 1, and the buffer bracket 4 is installed on the hopper 1. The buffer bracket 4 is used to provide support and buffer for the hopper 1. The buffer bracket 4 includes a frame 41, a telescopic rod 42, and a rubber pad 43. The frame 41 is installed on the ground at the discharge port of the concrete mixer. Multiple telescopic rods 42 are installed on the frame 41. The telescopic rods 42 always have a tendency to extend. The telescopic rod 42 includes a guide sleeve 421, a guide rod 422, and a buffer spring 423. The guide sleeve 421 is installed vertically on the frame 41. The guide rod 422 is slidably inserted into the guide sleeve 421. The buffer spring 423 is sleeved on the guide rod 422. One end of the buffer spring 423 is installed on the guide sleeve 421, and the other end of the buffer spring 423 is installed on the guide rod 422. The buffer spring 423 always has a tendency to drive the guide rod 422 away from the guide sleeve 421. The rubber pad 43 is installed on the guide rod 422 and abuts against the bottom of the hopper 1.

[0037] During the unloading process, the staff starts the vibration motor 3, which drives the hopper 1 to vibrate, thus driving the concrete in the hopper 1 to be unloaded quickly into the transport truck, increasing the unloading speed of the concrete in the hopper 1 and reducing the probability of the concrete clogging the hopper 1. During the vibration of the hopper 1, the hopper 1 can rotate vertically with the vibration. When rotating, the hopper 1 squeezes the rubber pad 43, and at the same time, the rubber pad 43 transmits the force to the guide rod 422, causing the guide rod 422 to slide in the guide sleeve 421 towards the guide sleeve 421. During the movement of the guide rod 422, it squeezes the buffer spring 423 to compress, thereby providing support for the hopper 1 during the vibration process and providing buffer for the hopper 1, reducing the possibility of damage to the hopper 1 during the vibration process and extending the service life of the hopper 1.

[0038] Reference Figure 1 , Figure 3 An adjusting mechanism 5 is installed on the hopper 1. The adjusting mechanism 5 is used to adjust the size of the discharge port of the hopper 1. The adjusting mechanism 5 includes a baffle 51 and a drive assembly 52. ​​A baffle 51 is hinged on each side of the hopper 1 in a direction that approaches each other. The baffle 51 is in contact with the inner wall of the hopper 1. The drive assembly 52 is installed on the hopper 1. The drive assembly 52 is used to drive the baffle 51 to rotate.

The worm 522 is rotatably installed on the hopper 1 and meshes with the worm gear 521.

[0039] The worker rotates the worm 522, the worm 522 drives the worm gear 521 to rotate, the worm gear 521 drives the articulated shaft of the baffle plate 51 to rotate, and then drives the baffle plate 51 to rotate towards the direction of approaching or moving away from the other baffle plate 51, adjusts the gap between the two baffle plates 51, and then adjusts the size of the opening between the two baffle plates 51, so that the flow of concrete flowing out of the hopper 1 can be controlled when the concrete flows out of the hopper 1, so that the worker can control the flow of concrete flowing out of the hopper 1 according to the demand, and in the process of rotating the baffle plate 51, the baffle plate 51 is attached to the inner wall of the hopper 1, and the baffle plate 51 can also push away the concrete adhered to the inner wall of the hopper 1, reduce the amount of concrete adhered to the inner wall of the hopper 1, and then reduce the probability of the hopper 1 being blocked.

[0040] The implementation principle of the concrete production discharge hopper according to an embodiment of the application is as follows: a worker rotates the hopper 1 to align the hopper 1 with the feed inlet of the transport tank car, and then discharges the concrete in the concrete mixer into the hopper 1, so that the concrete can be introduced into the transport tank car through the hopper 1. In the process of flowing of the concrete in the hopper 1, the cover 2 shields the upper part of the hopper 1, reduces the pollution of rainwater and dust to the concrete in the conveying process, and at the same time, the worker starts the vibration motor 3 to intermittently vibrate the hopper 1.
