[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, this embodiment provides a feeding system of a near-infrared soybean analyzer, comprising:

[0035] The hopper module 1 is used to collect and transport materials downward. In this embodiment, the material is soybean. Of course, in other optional implementations, the material can be adjusted according to actual needs.

[0036] The light-through material discharge module 2 has a material discharge channel connected to the lower end of the hopper module 1 and a swing unit located on one side of the material discharge direction inside the material discharge channel, and the swing unit can swing and reset during the material conveying process. The material discharge channel is used for the material to pass through, and the swing unit is used to swing with the material during the material conveying, so as to avoid the problem of bean jamming and ensure the normal discharge of the material. After the material to be conveyed passes through, the swing unit will reset, so as to solve the problem of bean jamming of subsequent materials.

[0037] The discharge module 3 is located below the discharge channel and is connected to the lower end of the discharge channel. Part of the swing unit is located in the discharge module 3. The lower end of the discharge module 3 has a discharge port 341. A feeding unit 33 is arranged inside the discharge module 3. The feeding unit 33 has a toggle member 331 for conveying materials. The feeding unit 33 is used to drive the material to move in the discharge module 3 through the toggle member 331 thereon, thereby ensuring continuous conveying of the material. The toggle member 331 has a blade-shaped partition 3311, and the blade-shaped partition 3311 is used to convey materials and drive the swing unit to deflect and reset.

[0038] The material receiving module 4 has a material receiving box 41 located at the lower end of the discharge port 341, and the material receiving box 41 is used to receive the tested soybeans, so that the material in the discharge module 3 can enter the discharge port 341 under the action of the feeding unit 33 and finally fall into the material receiving box 41 to realize the collection of the material.

[0039] In this embodiment, during operation, soybeans enter the hopper module 1, and fall from the lower end of the hopper module 1 into the discharge module 3 through the discharge channel. The driving member 331 of the feeding unit 33 rotates along the discharge direction, thereby driving the soybeans to be transported in the discharge direction. During this process, when the soybeans pass through the blade-shaped partition 3311 and the swing unit, the soybeans push the swing unit, causing the swing unit to swing. After a blade-shaped partition 3311 passes, the swing unit is reset, and this process is repeated to realize the transportation of soybeans, thereby avoiding the problem of soybean jamming during the soybean transportation process.

[0040] By means of the above structure, the soybeans are driven to move through the blade-shaped partition 3311, so that the swing unit is deflected and reset in the process, which can solve the problem of bean jamming and avoid manual intervention in bean discharge, thereby improving the soybean transportation efficiency and the accuracy of subsequent soybean analysis. In addition, compared with the existing technology, there is no need to add a new driving structure, the method is simple and the cost is low.

[0041] Specifically, the cross-section of the feed channel is square in a direction perpendicular to its extension direction, and the feed channel is formed by a feed chute body 21 and a feed chute side plate 22. In the present embodiment, the feed chute body 21 and the feed chute side plate 22 are both located directly below the hopper module 1, and the feed chute body 21 forms three sides of the feed channel, and the feed chute side plate 22 forms the fourth side of the feed channel, so that the feed channel is closed, thereby enabling the feed channel to have a better guiding and conveying effect on the material.

[0042] Specifically, the side plate 22 of the feed chute has a first circular light-through hole, and the side walls of the feed chute body 21 corresponding to the side plate 22 of the feed chute have a second circular light-through hole, and the first circular light-through hole and the second circular light-through hole are concentric. Figure 3 As shown, in this embodiment, the centers of the first circular light-through hole and the second circular light-through hole are both on the M line, and a single-sided frosted quartz glass 24 is fixed on the first circular light-through hole and the second circular light-through hole, and the frosted surface of the quartz glass 24 is on the side facing away from the feeding channel, so that the staff can understand the conveying status inside the feeding channel under the premise of ensuring the conveying of soybeans.

[0043] Specifically, the swing unit includes a swing plate 23, and a compression spring 25 is provided on one side of the swing plate 23 near the feeding channel. The swing plate 23 has a first rotating shaft and a second rotating shaft on both sides, respectively. The first rotating shaft and the second rotating shaft are respectively fixed to the feeding trough body 21 and the feeding trough side plate 22, and the centers of the first rotating shaft and the second rotating shaft are on a concentric line. The compression spring 25 makes the swing plate 23 have a reset tendency, thereby realizing the deflection and reset of the swing unit during the soybean transportation process, and the first rotating shaft and the second rotating shaft make the swing plate 23 rotate around them. Figure 3 and Figure 4 As shown, in this embodiment, the centers of the first rotation axis and the second rotation axis are both on the N line, wherein the N line is parallel to the M line, and the horizontal height difference between N and M is not greater than 4 mm, thereby preventing the swing plate 23 from blocking the first light hole and the second light hole when rotating.

[0044] Specifically, a swing rod 26 is fixedly provided at the center of the upper part of the swing plate 23, and the upper end of the swing rod 26 extends into the hopper module 1, wherein the diameter of the swing rod 26 is not greater than 1.5 mm, so as to prevent the soybeans from falling, and the distance between the portion of the upper end of the swing rod 26 extending into the hopper module 1 and the bottom of the hopper module 1 is not less than 5 mm. Figure 2As shown, the distance is represented by H, thereby ensuring that the swing rod 26 has sufficient driving effect on the soybeans in the hopper module 1. With the above structure, the swing rod 26 swings in the hopper module 1 during the rotation of the swing plate 23, thereby achieving a stirring effect on the soybeans inside the hopper module 1, thereby solving the problem of soybeans hanging in the hopper module 1 and ensuring the validity and accuracy of the data.

[0045] Specifically, the swing unit further includes a fixing plate 27 connected to the lower end of the swing plate 23. In this embodiment, the fixing plate 27 is made of rubber with a hardness of more than 75 degrees. Figure 6 As shown, the fixed plate 27 exceeds the swing plate 23 by a dimension J, wherein 5mm≥J≥3mm, so that the fixed plate 27 can avoid damaging the soybeans during the swinging process with the soybeans. Of course, in other optional embodiments, the specific material of the fixed plate 27 can be adjusted according to actual needs. The lower end of the fixed plate 27 extends into the discharge module 3, and the fixed plate 27 and the wall surface of the discharge channel located on its side are isolated from each other. It is particularly noted that when the swing plate 23 rotates, the top surface of the swing plate 23 never forms a vertical gap with the hopper module 1 to prevent soybeans from entering the gap. With the above structure, the fixed plate 27 has sufficient movement and deformation space during the rotation of the swing plate 23 around the rotation axis, which improves the movement stability of the swing plate 23 during the rotation process.

[0046] Specifically, the discharge module 3 includes a support frame 34 and a mounting plate 31 connected to the support frame 34, the mounting plate 31 communicates with the discharge channel and the support frame 34, the support frame 34 is provided with the feeding unit 33 inside, the feeding unit 33 is driven by a driving assembly 32, the driving assembly 32 includes a motor 321 and an auxiliary driven structure, the top of the blade-shaped partition 3311 is at a preset distance from the fixed plate 27, and the feeding unit 33 conveys the material under the drive of the driving unit. Preferably, the blade-shaped partition 3311 is made of rubber with a hardness of more than 70, such as Figure 6 As shown, the minimum distance between the top of the blade-shaped partition 3311 and the fixed plate 27 is K, where 8mm≥K≥3mm, so that there is an appropriate space between the blade-shaped partition 3311 and the fixed plate 27 for the movement of soybeans. The support frame 34 is used to support the motor 321 and the feeding unit 33, and at the same time forms a discharge channel including a feed port and a discharge port 341 with the mounting plate 31.

[0047] Specifically, the mounting plate 31 adjacent to the compression spring 25 is provided with an avoidance groove 311, and a maintenance cover 312 is provided above the avoidance groove 311 to prevent the soybeans from being blocked on the feeding path and improve the smoothness of the soybeans during the transportation process. The maintenance cover 312 can be detachably installed on the avoidance groove 311, thereby limiting the soybeans in the avoidance groove 311 and facilitating the inspection and maintenance of the avoidance groove 311.

[0048] Specifically, the receiving module 4 also includes a receiving chamber 43 for accommodating the receiving box 41. In the present embodiment, the receiving chamber 43 is made of carbon steel material, which is used to support the receiving box 41 and prevent dust from entering the device during the material unloading process. Of course, in other optional embodiments, the material of the receiving chamber 43 can be adjusted according to actual needs. The receiving chamber 43 is fixedly arranged below the discharge module 3. The receiving chamber 43 is provided with a Hall sensor 44 on the outer wall surface where the movement direction of the receiving box 41 is located. The receiving chamber 43 has a magnetic hole 431 corresponding to the Hall sensor 44 to prevent the formation of a shield that affects the magnetic force of the Hall sensor 44 receiving the magnet 42. The back of the receiving box 41 is provided with a magnet 42 corresponding to the magnetic hole 431. With the above structure, the magnet 42 can fix the receiving box 41, and can also transmit a signal through the proximity or separation of the magnet 42 and the Hall sensor 44 to determine whether the receiving box 41 is installed in place.

[0049] Specifically, the hopper module 1 is funnel-shaped, the lower end of the hopper module 1 has the smallest cross-sectional area and is connected to the upper end of the light-transmitting feeding module 2. The toggle member 331 drives the blade-shaped partition 3311 to pass directly under the hopper module 1 during the movement, so that the hopper module 1 has a better collection effect on the soybeans located therein. Figure 5 In an optional embodiment, the toggle member 331 is a transmission belt; Figure 8 As shown, in another optional embodiment, the toggle member 331 is a vertical dial; Fig. 9 As shown, in yet another optional embodiment, the driving member 331 is a horizontal dial wheel.
