[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Reference below Figures 1 to 7 A feeding device 100 according to an embodiment of the first aspect of the present invention will be described.

[0035] The feeding device 100 according to the first aspect of the present invention comprises: a feeding mechanism 2 .

[0036] Specifically, the feeding mechanism 2 includes: a storage bin 21 and a feeding assembly 22. A partition 2114 is provided in the storage bin 21. The partition 2114 divides the storage bin 21 into a storage section and a discharge section 213. The storage section is provided with a material receiving port 212, and the discharge section 213 is provided with a discharge port 214. A feeding port 2115 is provided at the lower end of the partition 2114, and materials are suitable for entering the discharge section 213 from the storage section through the feeding port 2115.

[0037] For example Figure 2 As shown, the material storage section and the material discharge section 213 can be adjacent to and arranged side by side in the moving direction of the material, so that the material in the material storage section can be more stable in the process of reaching the material discharge section 213 from the material storage section, and material jumping can be prevented; the material receiving port 212 can be formed by at least partially opening the upper end of the material storage section, and the material receiving port 212 is suitable for receiving the material falling from above it, and the material entering the material discharge section 213 eventually leaves the storage bin 21 from the material discharge port 214.

[0038] The storage bin 21 may be disposed on a feeding assembly 22 , and the feeding assembly 22 may be used to drive the material in the storage bin 21 to be transported toward the discharge port 214 .

[0039] According to the feeding device 100 of the present invention, the storage bin 21 is arranged on the feeding assembly 22, and a partition 2114 is arranged on the storage bin 21 to divide the storage bin 21 into a storage section and a discharge section 213, so that the storage section can be used to receive materials entering from the receiving port 212, thereby preventing the materials from splashing out of the storage bin 21. The materials entering the storage section can reach the discharge section 213 from the feeding port 2115, and finally leave the storage bin 21 from the discharge port 214. The setting of the feeding port 2115 facilitates the control of the maximum discharge speed and the maximum discharge flow rate of the materials when they are discharged from the storage bin 21.

[0040] In some embodiments, reference Figure 2 , Figure 3 and Figure 6 A rotatable baffle 215 is provided in the storage bin 21. The baffle 215 is located on the side of the partition 2114 facing away from the storage section (i.e. Figure 3 215 is at the side where the material discharging section is located as shown in the figure), when the baffle 215 is in the initial position (i.e., the baffle 215 is in the up and down direction of the natural falling state), the lower end of the baffle 215 blocks at least a part of the feeding port 2115, so that in the process of the material entering the material discharging section 213 from the feeding port 2115, the baffle 215 can rotate to a certain extent under the thrust of the material on the baffle 215, but due to the self-weight of the baffle 215, the rotation angle of the baffle 215 will not be too large, and due to the reaction force of the baffle 215 on the material, the baffle 215 can be rotated by Figure 3 The upper right side shown presses the material toward the lower left side, reducing the material that directly enters the discharge section 213 through the feed port 2115, thereby making the discharge of the discharge section 213 more uniform and the flow rate controllable.

[0041] In a specific example, the rotating end of the baffle 215 is located at the upper part of the discharge section 213, and the rotating axis of the baffle 215 is perpendicular to the moving direction of the material in the discharge section 213, so that it is easier to realize the rotation of the baffle 215 under the push of the material.

[0042] Furthermore, the baffle 215 includes: a plate body 2151 and a counterweight 2152, wherein the plate body 2151 is rotatably disposed on the partition 2114, the upper end of the plate body 2151 can be pivotally connected to the upper end of the partition 2114, and the counterweight 2152 can be detachably disposed on the plate body 2151, and the counterweight 2152 is located at the lower end of the plate body 2151, so that a counterweight 2152 of appropriate weight can be selected as needed to better improve the pressing effect of the plate body 2151 on the material, and selecting counterweights 2152 of different weights can control the rotation amplitude of the plate body 2151, thereby controlling the discharge rate of the material.

[0043] In some embodiments, the material storage section is provided with a material storage cavity 211 to accommodate materials, and a material receiving port 212 is connected to the material storage cavity 211. The material receiving port 212 can be formed at the top of the material storage cavity 211. The material storage cavity 211 is connected to the material discharge section 213 through a material feeding port 2115. The length of the material discharge section 213 is greater than or equal to a first preset length. The length of the material discharge section 213 can be reasonably set according to actual needs.

[0044] Optionally, the first preset length may be 0.1 m, 0.2 m or 0.3 m, etc. The specific length of the first preset length may be determined as required. When the material is conveyed through the discharge section 213, the first preset length of a suitable length may fully vibrate and convey the material to disperse it, ensuring that the material will not be aggregated together and is discharged from the discharge port 214 particle by particle. Therefore, the first preset length is not limited to 0.1 m, 0.2 m or 0.3 m, etc.

[0045] Further, refer to Figure 2 and Figure 3 The material storage section includes: a first side plate 2111, a second side plate 2112, and a third side plate 2113, wherein the first side plate 2111 and the second side plate 2112 are arranged opposite to each other and connected at the lower ends, the third side plate 2113 and the partition plate 2114 are arranged opposite to each other, the two ends of the third side plate 2113 are respectively connected to the first side plate 2111 and the second side plate 2112, and the two ends of the partition plate 2114 are respectively connected to the first side plate 2111 and the second side plate 2112, wherein the first side plate 2111, the second side plate 2112, the third side plate 2113 and the partition plate 2114 jointly define a material storage cavity 211, the upper end of the material storage cavity 211 forms a material receiving port 212, and the lower end of the partition plate 2114 and the first side plate 2111 and the second side plate 2112 define a feeding port 2115. Thus, the material can enter the storage chamber 211 from the receiving port 212 , and the material entering the storage chamber 211 enters the discharge section 213 through the feeding port 2115 , and finally leaves the storage bin 21 from the discharge port 214 of the discharge section 213 .

[0046] Furthermore, refer to Figure 2 and Figure 3, the angle between the first side plate 2111 and the second side plate 2112 can be 70-110 degrees, for example, the angle between the first side plate 2111 and the second side plate 2112 can be 70 degrees, 80 degrees, 90 degrees, 100 degrees or 110 degrees, preferably, the angle between the first side plate 2111 and the second side plate 2112 is 90 degrees, at this time, the cross section of the storage chamber 211 along the front-to-back direction is formed into a 90-degree V-shape, and the cross-sectional area of ​​the storage chamber 211 gradually decreases from top to bottom, so that the accumulation of materials in the storage chamber 211 can be prevented, so that the materials entering the storage chamber 211 can be transported away in time through the feeding port 2115 according to the appropriate flow rate. Of course, the angle between the first side plate 2111 and the second side plate 2112 is not limited to 70-110 degrees, and it can be specifically set according to needs.

[0047] The third side plate 2113 extends obliquely from top to bottom toward the direction close to the partition plate 2114. The angle between the third side plate 2113 and the vertical direction can be 10-50 degrees. For example, the angle between the third side plate 2113 and the vertical direction can be 10 degrees, 20 degrees, 30 degrees, 40 degrees or 50 degrees. Preferably, the angle between the third side plate 2113 and the vertical direction is 30 degrees, which can further promote the timely discharge of materials. Of course, the angle between the third side plate 2113 and the vertical direction is not limited to 10-50 degrees, and it can also be specifically set according to needs.

[0048] Optionally, the inner surface of the material storage cavity 211 is anodized to ensure that the material will not be blocked due to dust accumulation, or when the material is rice, for example, to ensure that the material will not be blocked due to rice bran accumulation.

[0049] According to some embodiments of the present invention, reference Figure 2 The lower end of the partition 2114 has an arc-shaped opening, and the arc-shaped opening and the first side plate 2111 and the second side plate 2112 define a feed port 2115, thereby making the structure smoother and facilitating feeding and discharging. At the same time, the arc-shaped opening is provided at the lower end of the partition 2114, which can ensure the flow rate of the discharge at the feed port 2115 and prevent the material from being blocked.

[0050] According to some embodiments of the present invention, reference Figures 1 to 4The feeding mechanism 2 may further include a connecting piece 216, which is connected to the feeding assembly 22 and the upper edge of the storage bin 21, respectively. In the up-down direction, the connecting piece 216 may be disposed between the feeding assembly 22 and the storage bin 21, and the upper edge of the connecting piece 216 may be detachably connected to the upper edge of the storage bin 21. In the conveying direction of the material, the setting position of the storage bin 21 is adjustable relative to the connecting piece 216, so that assembly is convenient. At the same time, the feeding assembly 22 and the upper edge of the storage bin 21 are connected by the connecting piece 216, so that the storage bin 21 is prevented from being connected to the inside of the storage bin 21 with connecting pieces such as bolts, and the protrusions formed by the connecting pieces such as bolts may affect the material, causing the problems of material accumulation, material blocking, and poor material discharge.

[0051] Further, refer to Figure 3 and Figure 4 The connecting piece 216 can be formed into a groove-shaped structure with a flat bottom wall. The upper ends of the two side walls of the connecting piece 216 in the front-to-back direction are formed with a first flange facing outward, and a plurality of bolt holes arranged at intervals along the left-to-right direction are formed on the first flange. A second flange matching the first flange is formed on the upper edge of any one of the first side plate 2111 and the second side plate 2112 of the storage bin 21, and a plurality of elongated holes corresponding to the bolt holes are formed on the second flange, and the elongated holes extend in the left-to-right direction. The bolt holes and the elongated holes can be connected by bolts. In this way, in the conveying direction of the material, the setting position of the storage bin 21 is adjustable relative to the connecting piece 216. At the same time, the elongated holes can facilitate the connection between the first flange and the second flange.

[0052] In a specific example, the feeding assembly 22 is a linear vibration feeding assembly. Compared with the disc spiral vibrator used in the related art, the linear vibration feeding assembly can increase the discharge speed and prevent discharge blockage caused by the adhesion of materials such as rice. At the same time, it can improve the material jumping situation and is easy to clean.

[0053] refer to Figure 1 and Figure 2 The linear vibration feeding assembly includes: a feeder 221 and a shock absorbing assembly. Specifically, the feeder 221 is connected to the storage bin 21, and the shock absorbing assembly is arranged below the feeder 221. The feeder 221 is suitable for being supported on the shock absorbing assembly, thereby, the shock absorbing assembly can reduce the vibration of the entire feeding device 100 caused by the vibration of the feeder 221, and reduce the working noise of the feeding device 100.

[0054] Furthermore, for example Figure 1 and Figure 2As shown, the shock absorbing assembly may include: a plurality of compression springs 222 and a mounting seat 223, wherein the plurality of compression springs 222 are clamped between the feeder 221 and the mounting seat 223, wherein the mounting seat 223 is provided with a plurality of bosses 2231 arranged at intervals, and the plurality of compression springs 222 are correspondingly sleeved on the outer sides of the plurality of bosses 2231, so that the connection between the compression spring 222 and the mounting seat 223 can be made more stable, and the compression spring 222 can be prevented from being separated from the installation position between the mounting seat 223 and the feeder 221 during operation.

[0055] According to some embodiments of the present invention, reference Figure 1 and Figure 5 The feeding device 100 further includes: a feeding mechanism 1, the feeding mechanism 1 has a feeding port 113 and a feeding port 123, and the feeding mechanism 1 further includes: a feeding pipe 11 and a feeding hopper 12. Specifically, the feeding port 113 can be formed in the feeding pipe 11, the feeding hopper 12 is connected to the feeding pipe 11, the feeding hopper 12 is located below the feeding pipe 11, the feeding port 123 is formed at the lower end of the feeding hopper 12, and at least a part of the feeding hopper 12 extends into the material storage section, so that the material entering the storage bin 21 from the feeding hopper 12 can be prevented from being too full and overflowing from the edge of the receiving port 212, and the feeding hopper 12 is spaced from the wall of the material storage section. For example, a avoidance opening can also be set at the upper part of the partition 2114, and the avoidance opening is used to avoid the lower end of the feeding hopper 12, so as to prevent the partition 2114 from contacting the lower end of the feeding hopper 12 and causing the vibration of the feeding hopper 12, thereby avoiding material jumping.

[0056] Furthermore, the feed hopper 12 and the feed pipe 11 may be connected via a feed cover, and the upper end of the feed hopper 12 may form an annular flange radially outward to facilitate connection with the feed cover.

[0057] Further, refer to Figure 1 The feed pipe 11 includes: a first feed section 111 and a second feed section 112. Specifically, the first feed section 111 extends in a vertical direction, a feed port 113 is formed at the upper end of the first feed section 111, and one end of the second feed section 112 ( Figure 1 The right end of the second feeding section 112 shown in FIG. 1 is connected to the first feeding section 111, and the other end of the second feeding section 112 ( Figure 1 The left end of the second feed section 112 shown in the figure extends downwardly and is inclined, and an overflow port 114 is formed at the other end of the second feed section 112. Therefore, when there is enough material entering the storage chamber 211 from the feed 11 through the feed hopper 12, the material will be accumulated in the feed hopper 12 and the feed pipe 11 from bottom to top. When the material overflows from the overflow port 114, it means that the amount of material fed in at this time has reached the target feeding amount.

[0058] In some embodiments, reference Figure 1 and Figure 5 The feed hopper 12 includes: a first hopper section 121 and a second hopper section 122. Specifically, the first hopper section 121 is connected to the feed pipe 11, and the cross-sectional area of ​​the first hopper section 121 gradually decreases from top to bottom, so that the amount of material entering the storage bin 21 can be further controlled; the upper end of the second hopper section 122 is connected to the first hopper section 121, and the lower end of the second hopper section 122 forms a material port 123, and the connection between the first hopper section 121 and the second hopper section 122 forms a bending structure, thereby, the bending structure can further buffer the speed of the material coming in from the feed pipe 11, reduce the impact on the storage bin 21, reduce material splashing, and ensure that the material enters the storage bin 21 smoothly.

[0059] A specific embodiment of the feeding device 100 according to the first aspect of the present invention and its working principle are described below.

[0060] The feed pipe 11, the feed hopper 12 and the feed cover are connected by a pan head combination screw, and the feed hopper 12 extends into the storage chamber 211 but does not contact it. The storage bin 21 is connected to the connecting piece 216 by a pan head combination screw. The baffle 215 is connected to the storage bin 21 by a pan head combination screw. The connecting piece 216 is connected to the feeder 221 by a pan head combination screw. The feeder 221 is connected to the vibrator fixing plate, and the vibrator fixing plate is connected to the compression spring 222 by hexagonal bolts. The compression spring 222 is elastically connected to the four bosses of the mounting seat 223.

[0061] The upper end of the feed hopper 12 is a circular ring structure for easy connection with the feed hood, and the lower end of the feed hopper 12 is made into an oblique cone shape, which mainly avoids the storage bin 21 and buffers the material. The feed hopper 12 is bent once, and its main functions are: the feed hopper 12 does not contact the storage bin 21, and the feed port 123 of the feed hopper 12 maintains a certain distance from the bottom of the storage bin 21, so that the feed hopper 12 can avoid the storage bin 21 to prevent resonance caused by contact with each other; the feed hopper 12 with a conical structure can buffer the speed of the material coming in from the feed pipe 11, reduce the impact on the storage bin 21, reduce material splashing, and ensure that the material enters the storage bin 21 smoothly.

[0062] The left side of the storage bin 21 is a storage section, and the right side is a discharge section 213. The storage section and the discharge section 213 are separated by a partition 2114. The material in the storage section is discharged through a feeding port 2115 at the lower part of the partition 2114, which can ensure the amount of material discharged and prevent material blockage. The upper edge of the partition 2114 is provided with a avoidance opening to avoid contact with the feed hopper 12.

[0063] In order to prevent the accumulation of materials in the storage chamber 211 in the storage bin 21, the storage chamber 211 and the discharge section 213 are both formed into a V-shaped structure, which can ensure both the discharge amount and the posture of the rice at the discharge port. In order to prevent the accumulation of materials at the corners of the storage chamber 211, the third side plate 2113 is tilted outward, and when the vibrator vibrates, all the materials are transported to the right to ensure that the storage bin 21 does not accumulate materials. The baffle 215 is fixed to the partition 2114 by a pan head combination screw, so that the discharge amount of the storage bin 21 can be adjusted.

[0064] The storage bin 21 forms a second flange on both sides along the front-to-back direction, and a long strip hole is set on the second flange so as to contact and fix with the connecting piece 216. This can avoid the accumulation of materials, blocking of materials and poor material discharge due to the presence of the bolt head inside the storage cavity 211.

[0065] The upper part of the connecting member 216 is connected to the long strip hole of the second flange of the storage chamber 211 by a hexagonal bolt, and the lower part of the connecting member 216 is connected to the threaded hole of the feeder 221 by a hexagonal bolt. The function of the mounting seat 223 is mainly to buffer the vibration force of the feeder 221 through the compression spring 222.

[0066] Here’s how it works:

[0067] When feeding, the material taking device takes the material once, and the amount of material falling into the feed pipe 11, the feed hopper 12, and the storage bin 21 is relatively large, and the speed is relatively fast; since the distance between the bottom end of the feed hopper 12 and the bottom end of the storage bin 21 is relatively short, the material will not overflow from the storage bin 21 after filling the storage bin 21, and will accumulate upward in the feed hopper 12, the feed cover, and the feed pipe 11 until the material overflows from the second feeding section 112 of the feed pipe 11; at this time, the capacity corresponding to the height of the storage bin 21, the feed hopper 12, and the feed cover to the second feeding section 112 is just enough to meet the capacity of the material to be inspected (for example, 5,000 grains of rice are required for inspection, and the number of materials accumulated from the storage bin 21 to the second feeding section 112 is exactly about 5,000 grains, which can just meet the quantity required for inspection).

[0068] Therefore, when the material begins to overflow from the second feeding section 112 of the feeding pipe 11, it indicates that the sampling quantity just meets the inspection requirement, and at this time, the material taking device can be closed to stop taking the material.

[0069] After stopping taking materials, the amount of materials accumulated between the storage bin 21 and the second feeding section 112 can meet the inspection requirements. Then, turn on the feeder 221, and the materials in the storage chamber 211 gain kinetic energy to move to the right. Under the action of the feeder 221, the materials pass through the feeding port 2115 at the bottom of the partition 2114 in sequence, in small amounts, and evenly, and move toward the discharge section 213. Since a baffle 215 is provided on the right side of the partition 2114, the upper end of the baffle 215 is fixed to the partition 2114 by a pan head combination screw; when the feeder 221 vibrates to the right, the baffle 215 has a tendency to move to the right, and it rotates around the pan head combination screw. When the feeder 221 vibrates to the right, the material moves to the right through the feeding port 2115 at the bottom of the partition 2114, and the baffle 215 also rotates to the right around the pan head combination screw, but the baffle 215 is under its own weight. Under the action of force, its rotation angle will not be very large, and when the feeder 221 moves to the left, the baffle 215 moves from the upper right side to the lower left side, which plays the role of pressing the material from the upper right side to the lower left side, making the feeding more uniform. At the same time, a counterweight block 2152 is provided at the lower end of the baffle 215. By adjusting the weight of the counterweight block 2152, the rotation angle of the baffle 215 can be adjusted, thereby adjusting the material flow through the feeding port 2115 into the discharge section.

[0070] Furthermore, in order to prevent clogging of the material by impurities such as pebbles, the aperture size of the feed port 2115 should be such that the flow rate of the material discharged therefrom into the discharge section 213 is greater than the flow rate requirement of the online grain quality detection equipment 200 for the material to be detected as in the second aspect of the embodiment of the present invention. Due to the pressing effect of the baffle 215, the flow rate of the material entering the discharge section 213 after being pressed by the baffle 215 just meets the flow rate requirement of the online grain quality detection equipment 200 for the material to be detected as in the second aspect of the embodiment of the present invention.

[0071] Furthermore, the weight of the baffle 215, the tightening degree of the pan head combination screw, etc. can be adjusted by the material movement speed displayed on the touch screen of the grain quality online detection device 200 of the second aspect of the embodiment of the present invention.
