Description

Technical Field

[0001] This utility model relates to the field of silo equipment technology, specifically a silo for quantitative material discharge. Background Technology

[0002] A silo is a structured container or warehouse space used to store bulk or large quantities of materials, and is widely used in various fields such as industrial production, logistics, and agriculture. Its main purpose is to efficiently store raw materials, semi-finished products, or finished products until these materials are further processed, sold, or transported.

[0003] Since the material in the silo is generally discharged through the silo outlet at the bottom of the silo, in order to quantitatively discharge the discharged material, a precision weighing mechanism is generally installed on the silo to control the discharge amount. Although this method achieves quantitative discharge of the material, the precision weighing mechanism is expensive, resulting in high production costs.

[0004] In view of this, there is an urgent need for a silo that dispenses material in a fixed quantity. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quantitative discharge hopper includes: a hopper and a metering mechanism. The top and bottom of the hopper are respectively provided with a feed inlet and a discharge outlet. The metering mechanism includes a feeding plate, a metering plate, a baffle, and a driving mechanism.

[0008] The feeding plate, metering plate, and baffle are all horizontally arranged inside the hopper.

[0009] The feeding plate divides the interior of the hopper into an upper cavity and a lower cavity. The feeding plate is provided with a feeding hole, and the upper cavity and the lower cavity are connected through the feeding hole.

[0010] The metering plate is rotatably mounted on the top surface of the feeding plate. The metering plate is provided with a plurality of metering holes. The driving mechanism is used to drive the metering plate to rotate so that the plurality of metering holes pass directly above the feeding holes in sequence.

[0011] The baffle is suspended above the feed plate and is positioned directly above the discharge hole.

[0012] A further feature is that,

[0013] There are two feeding holes, which are evenly distributed around the circumference of the feeding plate. There are also two baffles, which cover the two feeding holes directly above them.

[0014] Several of the metering holes are evenly distributed circumferentially on the circumferential side of the metering plate.

[0015] The driving mechanism includes a motor and a rotating shaft. The rotating shaft passes through the hopper from top to bottom. The motor is used to drive the rotating shaft to rotate. The metering plate is connected to the rotating shaft.

[0016] A first stirring rod is provided on the annular side of the rotating shaft at the upper cavity.

[0017] A second stirring rod is provided on the ring side of the rotating shaft at the lower cavity.

[0018] The upper cavity is cylindrical.

[0019] The lower cavity is funnel-shaped.

[0020] A flange is installed at the discharge port of the silo.

[0021] The baffle is arc-shaped, and its outer side is connected to the inner side of the hopper.

[0022] The above-described structure of this utility model can achieve the following beneficial effects:

[0023] In use, the material is placed in the upper chamber through the feed port and falls into the metering hole. The metering plate is driven to rotate by the drive mechanism. When the metering hole passes through the discharge hole, the material in the metering hole falls into the lower chamber and is discharged through the discharge port. Since the size of the metering hole is known, the rotation speed of the metering plate can be controlled to complete the timed and quantitative processing of the material discharged into the lower chamber, thereby ensuring quantitative output of material. It has the advantages of simple structure, low cost and is not easily interfered with. Attached Figure Description

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] refer to Figures 1-5 The illustrated hopper for quantitative discharge includes: a hopper 1 and a metering mechanism. The top and bottom of the hopper 1 are respectively provided with a feed inlet and a discharge outlet. The metering mechanism includes a discharge plate 2, a metering plate 3, a baffle 4, and a driving mechanism. The discharge plate 2, the metering plate 3, and the baffle 4 are all horizontally arranged in the inner cavity of the hopper 1. The discharge plate 2 divides the inner cavity of the hopper 1 into an upper cavity and a lower cavity. The discharge plate 2 is provided with a discharge hole 21, and the upper cavity and the lower cavity are connected through the discharge hole 21. The metering plate 3 is rotatably arranged on the top surface of the discharge plate 2. The metering plate 3 is provided with a plurality of metering holes 31. The driving mechanism is used to drive the metering plate 3 to rotate, so that the plurality of metering holes 31 pass directly above the discharge hole 21 in sequence. The baffle 4 is suspended above the metering plate 3 and is located directly above the discharge hole 21.

[0034] Based on the above structure, during use, the material is placed in the upper cavity through the feed port and falls into the metering hole 31. The metering plate 3 is driven to rotate by the drive mechanism. When the metering hole 31 passes through the discharge hole 21, the material in the metering hole 31 falls into the lower cavity and is discharged through the discharge port. Since the size of the metering hole 31 is known, the rotation speed of the metering plate 3 can be controlled to complete the timed and quantitative processing of the material discharged into the lower cavity, thereby ensuring quantitative output of material. It has the advantages of simple structure, low cost and is not easily interfered with.

[0035] like Figures 2-4As shown, there are two discharge holes 21, which are evenly distributed around the circumference of the discharge plate 2. There are also two baffles 4, which cover the two discharge holes 21 respectively (the baffles 4 are arc-shaped, and the outer side of the baffles 4 is connected to the inner side of the hopper 1). By setting two discharge holes 21, the efficiency of material output is improved. In addition, several metering holes 31 are evenly distributed around the circumference of the metering plate 3. This can further improve the stability and accuracy of quantitative material discharge and facilitate the control of material output.

[0036] like Figure 1 As shown, the drive mechanism includes a motor 5 and a rotating shaft 6. The rotating shaft 6 is coaxially installed in the hopper 1 from top to bottom. The motor 5 is used to drive the rotating shaft 6 to rotate. The metering plate 3 is coaxially connected to the rotating shaft 6. By driving the rotating shaft 6 to rotate through the motor 5, the metering plate 3 can be rotated. By controlling the output power of the motor 5, the rotation speed of the metering plate 3 can be controlled, thereby realizing the control of the material output efficiency.

[0037] Further optimizations include, for example Figure 1 As shown, in order to avoid material blockage in the upper or lower chamber, a first stirring rod 7 is provided on the circumferential side of the rotating shaft 6 in the upper chamber, and a second stirring rod 8 is provided on the circumferential side of the rotating shaft 6 in the lower chamber. The material in the chamber is cleared by the first stirring rod 7 and the second stirring rod 8 to ensure the stability of the quantitative output material.

[0038] Further optimizations include, for example Figure 1 As shown, the upper cavity is cylindrical to accommodate more material; the lower cavity is funnel-shaped to facilitate material output from the hopper 1; and a flange 9 is provided at the outlet of the hopper 1 to facilitate connection to external pipelines.

[0039] In summary, during use, the material is placed in the upper cavity through the feed inlet and falls into the metering hole 31. The metering plate 3 is driven to rotate by the drive mechanism. When the metering hole 31 passes through the discharge hole 21, the material in the metering hole 31 falls into the lower cavity and is discharged through the discharge port. Since the size of the metering hole 31 is known, the rotation speed of the metering plate 3 can be controlled to complete the timed and quantitative processing of the material discharged into the lower cavity, thereby ensuring quantitative output of material. It has the advantages of simple structure, low cost and is not easily interfered with.

[0040] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
