[0030] The present application proposes a hopper assembly 100, which is applied to a feeding device of a concrete mixing station. The hopper assembly 100 is formed with a feeding bin. A loader transports raw materials to the feeding bin of the hopper assembly 100, and then uses a feeding belt of the feeding device to transport the raw materials to a mixer.
[0031] Please refer to Figures 1 to 3 In an embodiment of the present application, the hopper assembly 100 includes a support member 10, a hopper 20 and a vibrator 30; wherein the support member 10 is fixedly installed above the feeding belt of the feeding device; the hopper 20 is installed on the support member 10, the feed port 21 of the hopper 20 is exposed above the support member 10, the discharge port 22 of the hopper 20 is arranged opposite to the feeding belt of the feeding device, and the vibrator 30 is provided on the side of the hopper 20 facing the support member 10.
[0032] In some examples, the support member 10 may be a concrete member, and in other examples, the support member 10 may also be a steel frame structure. The support member 10 mainly serves to fix the hopper 20, so that when the loader transports raw materials to the hopper 20, the hopper 20 can maintain relative stability.
[0033] It can be understood that the hopper 20 is usually larger at the top and smaller at the bottom, that is, the feed port 21 of the hopper 20 is larger than the discharge port 22 of the hopper 20; an upper bin is formed between the feed port 21 and the discharge port 22, and the upper bin can be used for the flow of raw materials, that is, the raw materials enter the upper bin from the feed port 21, and then flow out of the upper bin through the discharge port 22 and fall onto the feeding belt located below.
[0034] The vibrator 30 can be fixed to the side of the hopper 20 facing the support 10 by welding, threaded connection, etc., wherein the vibrator 30 can vibrate the hopper 20 when working, which can effectively help the raw material agglomerates to vibrate and disperse, and avoid the raw materials from accumulating around the upper silo. In a specific application scenario, the control switch of the vibrator 30 can be set on the mixing plant and controlled by the operator.
[0035] The present application adopts the above technical solution, and a vibrator 30 is provided on the side of the hopper 20 facing the support 10. When the raw materials are accumulated in the upper bin of the hopper 20, the raw materials can be vibrated and dispersed by the vibration of the vibrator 30, so that the raw materials accumulated in the hopper 20 can flow smoothly to the feeding belt through the discharge port 22 without manual cleaning. On the one hand, the raw materials are prevented from accumulating in the hopper 20 assembly 100, so as to improve the feeding efficiency of the feeding device, thereby improving the production efficiency of the mixing station, and on the other hand, it is avoided that the raw materials are manually assisted in cleaning the accumulated raw materials, so as to save human resources. At the same time, since the raw materials will not be accumulated on the hopper 20 for a long time, the pressure of the hopper 20 stacking can also be reduced.
[0036] In some examples, such as Figures 1 to 3 As shown, the support member 10 is a concrete component, the hopper 20 is formed by splicing steel plates, and the hopper assembly 100 also includes a connecting member 40, one side of the connecting member 40 is connected to the side of the concrete component away from the discharge port 22, and the other side of the connecting member 40 is connected to the side of the steel plate away from the discharge port 22.
[0037] There are many types of the connecting member 40. In some examples, the connecting member 40 is made of a flexible material that can be stretched. In some examples, the connecting member 40 is made of a rigid material that cannot be stretched or is not easily stretched.
[0038] With such arrangement, when the loader pours raw materials into the upper bin of the hopper 20, it can prevent the raw materials from falling from between the concrete components and the steel plates into the side of the hopper 20 away from the upper bin, i.e., prevent the raw materials from being dragged into the position where the vibrator 30 is located, thereby improving the reliability of the hopper assembly 100.
[0039] In some examples, such as Figure 1 and Figure 3 As shown, the concrete component is pre-embedded with steel bars 11, and the side of the steel plate facing the concrete component is fixed to the concrete component by welding with the steel bars 11.
[0040] With such arrangement, the steel bars 11 can stably support the steel plate, and can prevent the steel plate from being displaced or deformed in the hand due to excessive impact force when the raw materials fall into the hopper 20.
[0041] In some examples, such as Figure 1 and Figure 3 As shown, the hopper 20 includes a plurality of steel plates, which are welded and fixed to each other, and the plurality of steel plates are fixed to the concrete member by welding with the steel bars 11. A vibrator 30 may be provided on each steel plate.
[0042] Such a configuration is intended to further improve the stability of the hopper 20, thereby providing the impact resistance of the hopper 20. Specifically, the hopper 20 may include three steel plates, or the hopper 20 may also include four steel plates. In conjunction with the above-mentioned content of the connecting member 40, in this example, the connecting member 40 may be a rigid metal material.
[0043] In some examples, such as Figure 1 and Figure 2 As shown, the connecting piece 40 is a first flexible cloth, and the hopper 20 includes a first steel plate 23 and two second steel plates 24 respectively arranged on both sides of the first steel plate 23, and the two second steel plates 24 are arranged opposite to each other; the first steel plate 23 is fixed to the concrete member by welding with the steel bars 11 pre-embedded in the concrete member on the side facing the concrete member, and the two second steel plates 24 are rotatably installed on the concrete member on one side close to the discharge port 22, so that the other side of the two second steel plates 24 away from the discharge port 22 can approach or move away from each other to adjust the size of the feed port 21 of the hopper 20.
[0044] The movement of the two second steel plates 24 can be directly operated manually or driven by a power mechanism.
[0045] With such arrangement, when the discharge port 22 of the hopper 20 becomes smaller, the inclination angle of the two second steel plates 24 will increase, which is more conducive to the raw materials falling into the feeding belt below. When the feed port 21 of the hopper 20 becomes larger, the inclination angle of the two second steel plates 24 will decrease, which is more conducive to the loader pouring the raw materials into the hopper 20. At the same time, when too much raw materials are piled up around the upper bin of the hopper 20 and the vibrator 30 cannot fully play its role, the inclination angle of the two second steel plates 24 will increase, and the raw materials can be pushed down the feeding belt by the gravity of the raw materials themselves.
[0046] In order to allow the two second steel plates 24 to rotate smoothly, a movable gap must be reserved between the first steel plate 23 and the two second steel plates 24. Considering that when the loader pours the raw materials into the upper bin of the hopper 20, the raw materials will fall into the gap between the first steel plate 23 and the second steel plate 24, in some examples, such as Figure 1 and Figure 2 As shown, two sides of the first steel plate 23 are spliced with two second steel plates 24 through second flexible fabrics 25 respectively.
[0047] With such arrangement, when the loader pours raw materials into the upper bin of the hopper 20, it can prevent the raw materials from falling from between the first steel plate 23 and the second steel plate 24 into the side of the hopper 20 away from the upper bin, i.e., it can prevent the raw materials from being dragged into the position where the vibrator 30 is located, thereby improving the reliability of the hopper assembly 100.
[0048] In some examples, such as Figure 1 and Figure 2 As shown, the hopper assembly 100 further includes two hydraulic cylinders 50 , which are respectively fixedly mounted on the concrete components, and the output ends of the two hydraulic cylinders 50 are respectively fixedly connected to the two second steel plates 24 .
[0049] This arrangement is intended to facilitate adjustment of the size of the feed port 21 of the hopper 20, thereby facilitating control of the inclination angle of the two second steel plates 24. Similarly, in a specific application scenario, the control switch of the hydraulic cylinder 50 can be set in the mixing plant and controlled by an operator.
[0050] Preferably, the acute angle formed between the second steel plate 24 and the horizontal plane is α, wherein 70°≤α≤80°.
[0051] In some examples, such as Figure 1 As shown, a steel bar 11 mesh is also provided at the discharge port 22 of the hopper 20. Such a configuration can prevent debris or oversized stones from falling into the feeding belt.
[0052] The present application also proposes a feeding device, which includes a feeding belt and a hopper assembly 100. The specific structure of the hopper assembly 100 refers to the above embodiment. Since the present feeding device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the hopper assembly 100 is fixedly installed above the feeding belt, and the discharge port 22 of the hopper 20 is arranged directly opposite to the feeding belt of the feeding device.
[0053] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
