Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of soybean processing equipment, and specifically relates to a double-headed receiving hopper for soybean screening. Background Technology
[0002] Currently, the main steps in soybean processing include screening and impurity removal, soaking and crushing, steaming and softening, pressing and extraction (to obtain soybean oil and soybean meal) or grinding and coagulation (to make tofu and other soybean products), filtration and separation, refining (for soybean oil), and shaping and packaging.
[0003] The screening and impurity removal step removes impurities, broken beans, and misshapen beans from soybeans, ensuring the purity and overall quality of the soybeans. The screened soybeans are more uniform in shape and size, which helps to improve pressing efficiency and oil extraction rate, and reduce production costs. Screening also helps to ensure the quality of soybean raw materials, thereby guaranteeing the quality and stability of subsequent processed products.
[0004] In existing technologies, after soybeans are screened by a fine-tuning device, they are generally collected directly at the discharge port of the device using a hopper, or a single-headed hopper is placed at the discharge port for buffering. However, with the direct collection method, the soybeans fall from the discharge port at a relatively high speed, which can easily cause soybeans to scatter when the hopper is changed. With the single-headed hopper buffering method, since there is only one discharge port, the discharge port is closed to prevent soybeans from scattering when the hopper is changed, which can lead to overflow of the hopper due to untimely discharge. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing a double-headed receiving hopper for soybean screening. The specific technical solution is as follows:
[0006] This utility model provides a double-headed receiving hopper for soybean screening, including a rectangular hopper, which is supported and connected to a clamping frame on its bottom surface; an L-shaped discharge port is symmetrically opened along the centerline of the bottom of one outer side of the rectangular hopper, and a diversion groove is provided on the discharge port at an outward inclination.
[0007] The diversion channel includes a bottom guide plate that is integrally inclined downward to the horizontal end face of the corresponding discharge port. A side baffle is integrally vertically connected to the side of the bottom guide plate that extends out of the discharge port. A slot is vertically opened between the two side baffles and the outer surface of the corresponding rectangular hopper, and the bottom surface of the slot is flush with the top surface of the bottom guide plate. A gate plate for adjusting the opening size of the corresponding discharge port is inserted into the slot.
[0008] As a preferred technical solution of this utility model, an elongated hole is provided through the upper part of the gate plate along its centerline, and a positioning element is provided through the gap in the elongated hole. The positioning element is screwed into a screw hole on the outer surface of the rectangular bucket to position and press the corresponding gate plate.
[0009] As a preferred technical solution of this utility model, the positioning component includes a rotating cap, and a circular pressure plate is integrally and vertically connected to the inner end face of the rotating cap. A stud is integrally and vertically connected to the inner end face of the circular pressure plate. The stud passes through the corresponding elongated hole and is fixedly screwed to the screw hole, so that the circular pressure plate positions and presses the gate.
[0010] As a preferred technical solution of this utility model, the gate is kept in a limiting engagement with the side baffle of the diversion channel by the limiting ridges that are integrally and vertically symmetrically connected on both sides.
[0011] As a preferred technical solution of this utility model, the top surface of the gate is integrally vertically connected with a T-shaped lifting rib.
[0012] As a preferred technical solution of this utility model, the clamping frame includes a cross plate, and clamping plates are respectively connected to the four end faces of the cross plate in pairs perpendicularly and symmetrically. The cross plate and the clamping plates cooperate to clamp the bottom of the rectangular bucket. Support legs are respectively connected to the bottom faces of the four ends of the cross plate in pairs perpendicularly and symmetrically. A rectangular bottom support plate is vertically connected to the bottom end of the four support legs.
[0013] As a preferred technical solution of this utility model, the pair of card plates are respectively fixedly screwed to the outer surface of the corresponding rectangular bucket by a fastening bolt adapted thereto.
[0014] As a preferred embodiment of this utility model, universal wheels are symmetrically arranged at the four corners of the bottom surface of the bottom support plate.
[0015] The beneficial effects of this utility model are:
[0016] This utility model features two L-shaped discharge ports symmetrically arranged along the centerline at the bottom of a rectangular hopper. This dual-head design allows one discharge port to continue operating while the other can be closed for hopper replacement, thus avoiding the overflow problem caused by closing the discharge port when replacing hoppers in traditional single-head hoppers. The alternating operation of the dual heads greatly improves the efficiency and flexibility of receiving materials.
[0017] Each feed port is equipped with an outward-sloping diversion channel, which includes a bottom guide plate and a side baffle. The bottom guide plate is integrally connected to the horizontal end face of the feed port at an angle downwards. This helps to guide the soybeans to flow out smoothly and orderly, reducing the impact force when the soybeans fall and preventing them from scattering. The side baffle prevents the soybeans from overflowing from the side, ensuring the accuracy of the receiving.
[0018] The slot design allows the gate to be inserted and fitted into the slot to adjust the opening size of the corresponding discharge port. This design can flexibly adjust the discharge speed according to actual production needs, so that the material can be discharged quickly when needed, or the discharge amount can be reduced when changing the material bucket to prevent overflow. The adjustability of the gate enhances the adaptability and controllability of the receiving hopper. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0027] Example 1
[0028] To address the technical problems in the background section, the following double-headed hopper for soybean screening is provided:
[0029] Combination Figures 1-3As shown, a double-headed receiving hopper for soybean screening includes a rectangular hopper 1, which is supported and connected to a support frame 5 on its bottom surface; an L-shaped discharge port 11 is symmetrically opened along the centerline on the bottom of one outer side of the rectangular hopper 1, and a diversion groove 2 is provided on the discharge port 11 at an outward inclination.
[0030] The diversion channel 2 includes a bottom guide plate 21 that is integrally inclined downward to the horizontal end face of the corresponding discharge port 11. The side of the bottom guide plate 21 extending out of the discharge port 11 is integrally vertically connected to a side baffle 22. A slot 23 is vertically opened between the two side baffles 22 and the outer surface of the corresponding rectangular hopper 1, and the bottom surface of the slot 23 is flush with the top surface of the bottom guide plate 21. A gate 3 for adjusting the opening size of the corresponding discharge port 11 is inserted into the slot 23.
[0031] By adopting the above technical solution, the receiving hopper has two L-shaped discharge ports 11 symmetrically opened along the center line at the bottom of the rectangular hopper 1. This dual-head design allows one discharge port to continue working while the other discharge port can be closed for material replacement, thus avoiding the overflow problem caused by closing the discharge port when replacing the material in the traditional single-head receiving hopper; the alternating dual-head operation greatly improves the receiving efficiency and flexibility.
[0032] Each discharge port 11 is provided with a flow channel 2 that is inclined outward. The flow channel 2 includes a bottom guide plate 21 and a side baffle 22. The bottom guide plate 21 is integrally connected to the horizontal end face of the discharge port 11 and inclined downward. This helps to guide the soybeans to flow out smoothly and orderly, reduces the impact force when the soybeans fall, and avoids scattering. The side baffle 22 prevents the soybeans from overflowing from the side and ensures the accuracy of receiving the material.
[0033] The design of slot 23 allows the gate 3 to be inserted and fitted in the slot to adjust the opening size of the corresponding discharge port 11. This design can flexibly adjust the discharge speed according to actual production needs, so that the material can be discharged quickly when needed, or the discharge amount can be reduced when changing the material bucket to prevent overflow. The adjustability of the gate enhances the adaptability and controllability of the receiving hopper.
[0034] Example 2
[0035] Combination Figure 1 , Figure 4 and Figure 5 As shown, based on the above embodiments, this embodiment further provides the following:
[0036] In this embodiment, as Figure 1 and Figure 4As shown, an elongated hole 31 is provided through the upper part of the gate plate 3 along its centerline. A positioning element 4 is provided through the gap in the elongated hole 31. The positioning element 4 is screwed into the screw hole 12 on the outer surface of the rectangular bucket 1 to position and press the corresponding gate plate 3.
[0037] By adopting the above technical solution, the elongated hole 31 through the center line of the gate plate 3 allows the positioning member 4 to slide freely in the hole. In this way, the depth of the gate plate 3 inserted into the slot 23 can be flexibly controlled by adjusting the position of the positioning member 4 in the elongated hole 31 according to actual production needs, thereby adjusting the opening size of the corresponding feed port 11. This design not only improves the adaptability of the receiving hopper, but also effectively prevents soybeans from scattering or overflowing due to excessive feeding while meeting production needs.
[0038] The positioning component 4 is screwed into the screw hole 12 on the outer surface of the rectangular hopper 1. This connection method ensures that the gate plate 3 can be accurately positioned and firmly pressed after the position is adjusted. By rotating the positioning component 4, it can be tightly fitted with the screw hole 12, thereby preventing the gate plate 3 from loosening or shifting under vibration or impact, and ensuring the stability and reliability of the receiving hopper.
[0039] like Figure 5 As shown, the positioning component 4 includes a rotating cap 41, and a circular pressure plate 42 is integrally and vertically connected to the inner end face of the rotating cap 41. A stud 43 is integrally and vertically connected to the inner end face of the circular pressure plate 42. The stud 43 passes through the corresponding elongated hole 31 with a gap and is fixedly screwed to the screw hole 12, so that the circular pressure plate 42 positions and presses the gate plate 3.
[0040] By adopting the above technical solution, the positioning component 4 is composed of a rotating cap 41, a circular pressure plate 42 and a stud 43. The stud 43 passes through the elongated hole 31 on the gate plate 3 and is fixedly screwed to the screw hole 12 on the outer surface of the rectangular bucket 1. This design allows the operator to rotate the rotating cap 41 to drive the stud 43 to rotate in the screw hole 12, thereby achieving precise adjustment and stable pressing of the position of the gate plate 3.
[0041] The positioning component 4 is relatively simple in design, easy to operate and maintain. Operators can adjust and tighten the gate 3 simply by rotating the rotating cap 41, without the need for complicated tools or skills. At the same time, since the rotating cap 41, the circular pressure plate 42 and the stud 43 are integrated, they have high strength and durability, and can withstand the impact and friction of soybeans falling for a long time without being easily damaged or deformed.
[0042] like Figure 5 As shown, the gate 3 is kept in a limiting engagement with the side baffle 22 of the diversion channel 2 by the limiting ribs 32 that are integrally and vertically symmetrically connected on both sides.
[0043] By adopting the above technical solution, the limiting rib 32 is integrated vertically and symmetrically connected to both sides of the gate plate 3, forming a limiting engagement with the side baffle 22 of the diversion channel 2. This design can ensure that the gate plate 3 slides stably in the slot 23 and is not prone to displacement or shaking. Even when the gate plate 3 is subjected to the impact force of soybeans falling, the limiting rib 32 can provide additional support force to maintain the stable position of the gate plate 3, thereby ensuring that the opening size of the discharge port 11 is precisely controlled.
[0044] The addition of the limiting ridge 32 not only increases the contact area between the gate 3 and the side baffle 22, but also enhances the overall structural strength of the gate 3; this makes the gate 3 more durable when subjected to the impact force of falling soybeans, and less prone to deformation or damage.
[0045] like Figure 5 As shown, the top surface of the gate 3 is vertically connected with a T-shaped lifting rib 33.
[0046] By adopting the above technical solution, the lifting rib 33 adopts a T-shaped structure design, which allows the operator to easily lift the gate plate 3 by hand or tool. When it is necessary to adjust the opening size of the feed port 11, the operator only needs to lift the lifting rib 33 to lift the gate plate 3 from the slot 23, then adjust the position of the gate plate 3 as needed, and finally fix the gate plate 3 by the positioning part 4. This operation method is simple and quick, which greatly improves work efficiency.
[0047] Example 3
[0048] Combination Figure 1 and Figure 6 As shown, based on the above embodiments, this embodiment further provides the following:
[0049] In this embodiment, as Figure 1 and Figure 6 As shown, the clamping frame 5 includes a cross plate 51, and clamping plates 511 are connected to each of the four end faces of the cross plate 51 in pairs. The cross plate 51 and the clamping plates 511 cooperate to clamp the bottom of the rectangular bucket 1. Support legs 52 are connected to each of the four end bottom faces of the cross plate 51 in pairs in pairs. The bottom ends of the four support legs 52 are vertically connected to a rectangular bottom support plate 53.
[0050] By adopting the above technical solution, the cross plate 51 of the clamping frame 5 cooperates with the four clamping plates 511 to form a stable clamping structure, which can firmly clamp the bottom of the rectangular hopper 1. This design not only ensures the stability of the receiving hopper during use, but also prevents the receiving hopper from shaking or falling off due to vibration or external force, thereby ensuring the continuity and safety of the receiving process.
[0051] The four ends of the cross plate 51 are each vertically and symmetrically connected to two support legs 52, and the bottom ends of the four support legs 52 are vertically connected to a rectangular bottom support plate 53. This design forms a stable support system, which allows the receiving hopper to be placed stably on the ground or other support surfaces, further enhancing the stability and load-bearing capacity of the receiving hopper. Preferably, the support legs 52 can also be designed to be height-adjustable to accommodate the unloading port of the sorting equipment at different heights.
[0052] Because the clamping bracket 5 uses a snap-fit method to fix the rectangular hopper 1, the installation process is relatively simple and quick. The operator only needs to align the bottom of the rectangular hopper 1 with the clamping plate 511 of the clamping bracket 5 and then gently press down to fix it. This design not only saves installation time but also reduces installation difficulty, improves work efficiency, and facilitates the cleaning, maintenance, and replacement of the hopper in the later stages, thus extending the service life of the equipment.
[0053] like Figure 6 As shown, a pair of the card plates 511 are respectively fixedly screwed to the outer facade of the corresponding rectangular bucket 1 by fastening bolts 512 that are adapted to them.
[0054] By adopting the above technical solution, the fastening bolt 512 tightly connects the clamping plate 511 to the outer surface of the rectangular hopper 1 through a screw connection. This connection method is not only firm and reliable, but also effectively resists forces and vibrations from all directions. During the screening and impurity removal process, the impact force generated when soybeans fall and the vibration generated during equipment operation may affect the stability of the receiving hopper. The use of fastening bolt 512 greatly enhances the overall structural stability of the receiving hopper, ensuring that it will not shake or fall off during operation.
[0055] like Figure 6 As shown, universal wheels 531 are symmetrically arranged at the four corners of the bottom surface of the bottom support plate 53.
[0056] By adopting the above technical solution, universal wheels 531 are symmetrically arranged at the four corners of the bottom surface of the bottom support plate 53, which allows the entire receiving hopper to move easily within the working area. Whether moving from one workstation to another or making fine adjustments within the same workstation, the operator only needs to push the receiving hopper to achieve rapid movement. This design greatly improves the mobility of the receiving hopper, making the soybean screening process smoother and more efficient;
[0057] Traditional receiving hoppers often require operators to laboriously move or lift them, which not only increases manual labor intensity but may also affect work efficiency and safety. However, with receiving hoppers equipped with casters 531, operators can easily move and position the hopper by simply pushing it, greatly reducing manual labor intensity.
[0058] Working principle and usage process of this utility model:
[0059] In use, soybeans are first screened by a fine-selection device and then fall into the rectangular hopper 1 of the double-headed receiving hopper, and flow out through two diversion channels 2. The gate 3 can control the opening size of the discharge port 11 by adjusting the depth of its insertion into the slot 23, thereby adjusting the flow rate of soybeans.
[0060] A long hole 31 is provided through the upper part of the gate plate 3 along its centerline, and a positioning element 4 is inserted through the gap in the long hole 31. When it is necessary to adjust the soybean flow rate, the operator can rotate the rotating cap 41 of the positioning element 4 to make the stud 43 screw in or out of the screw hole 12, thereby driving the circular pressure plate 42 to move axially, so as to loosen or tighten the gate plate 3, and then adjust the position of the gate plate 3.
[0061] Meanwhile, the limiting ribs 32, which are integrated vertically symmetrically connected on both sides of the gate plate 3, are locked to the side baffles 22 of the diversion channel 2 to ensure that the gate plate 3 will not shake during the adjustment process; the top surface of the gate plate 3 is also integrated vertically connected with a T-shaped lifting rib 33, which makes it convenient for operators to lift the gate plate 3 for adjustment.
[0062] The rectangular hopper 1 is supported and connected by a clamping bracket 5 on its bottom surface. The clamping bracket 5 consists of a cross plate 51, a clamping plate 511, support legs 52, and a bottom support plate 53. A pair of clamping plates 511 are fixedly screwed to the outer surface of the rectangular hopper 1 by fastening bolts 512, ensuring the stability of the rectangular hopper 1. Universal wheels 531 are symmetrically arranged at the four corners of the bottom surface of the bottom support plate 53, facilitating the movement and positioning of the receiving hopper by the operator.
[0063] Throughout the entire process, operators can adjust the position of gate 3 at any time according to actual needs to control the flow rate of soybeans and ensure the smooth and efficient soybean screening process.
[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
