Description

Technical Field

[0001] This utility model relates to the technical field of material weighing devices and counting devices during weighing, and particularly to a grain counting weighing machine. Background Technology

[0002] Most current grain counting machines are linear machines arranged horizontally, see appendix. Figure 1 The vibrating feeder 801 is located at the rear end of the vibrating conveyor 802 and adopts a rear-end feeding mode. The line scan camera 805 (i.e., the counting camera) is located above the front of the vibrating conveyor, and the light source 806 is located below the vibrating conveyor. During the process of the material falling from the vibrating conveyor to the storage hopper 803, the visual light path 808 in the visual recognition area 807 generates an obstruction shadow. The line scan camera calculates the material quantity from the shadow.

[0003] To obtain the target quantity of material using the aforementioned linear counting machine, the quantity of material entering the storage hopper is controlled, with each hopper receiving one unit of material that meets the target quantity. If the material in the storage hopper is qualified, it enters the subsequent packaging process through the branch chute 804; if the material in the storage hopper is unqualified, it is directly discharged into the waste bin 809.

[0004] To ensure the material in the hopper meets the target quantity, the feeding rate of the vibrating conveyor must be controlled while counting the grains. When the feeding quantity approaches the target quantity, the speed of the vibrating conveyor needs to be slowed down to achieve a higher accuracy in approaching the target quantity. When the feeding quantity reaches the target quantity, the vibrating conveyor stops. This control method reduces the counting speed. To increase the counting speed while maintaining accuracy, the number of units in the linear grain counter must be increased, and these units must be arranged horizontally. However, increasing the number of units leads to problems such as increased size, increased cost, and uneven feeding. Utility Model Content

[0029] The counting camera feeds back the quantity of material fed to the control unit.

[0030] In view of the above technical features, the present invention has the following beneficial effects:

[0031] 1. This utility model discloses a grain counting and weighing machine that utilizes several vibrating conveyor discs to form a circular or annular vibrating feeding area. This increases the feeding capacity and allows the material from the feeding cone to disperse radially, achieving appropriate material separation and resulting in more uniform feeding. The annular arrangement significantly reduces volume and cost compared to existing horizontally arranged units, making it possible to increase the number of units. When the number of counting units is greater than or equal to 10, combined calculations can be performed. At this point, there are no strict requirements on the quantity of material falling into the counting hopper, and the vibrating conveyor discs do not need to decelerate, thereby increasing the counting speed.

[0032] 2. The present invention provides a particle counting and weighing machine, which, in addition to a main vibrator that drives the top cone to vibrate, uses two-stage vibrators to drive two-stage vibrating discs to help the material coming down from the top cone to be further dispersed, falling one by one from all sides and being captured by a camera device, thereby achieving accurate and efficient particle counting.

[0033] 3. In this utility model, a grain counting and weighing machine has a material moving trough on the second-stage vibrating plate in the outer ring. The front end of the material moving trough corresponds to the discharge end of the second-stage vibrating plate. The front end of the protrusion between adjacent material moving troughs is also provided with a separating part. The separating part can separate the material falling from the discharge end of the second-stage vibrating plate at the moment of falling, so as to avoid the overlap of material passing through the optical path after falling as much as possible, and ensure that the material falling from each material moving trough can be captured by the grain counting camera, thus ensuring the counting accuracy of the grain counting and weighing machine.

[0034] 3. In this invention, a grain counting and weighing machine has a camera device located inside the central column of the light source module, which avoids accidental contact with the camera device, protects the camera device to the greatest extent, and ensures its safety and positional accuracy.

[0035] 4. The present invention provides a counting and weighing machine, wherein a transparent window and an air pipe are provided on the central column for the passage of light. The transparent window is covered with optical glass, and the air pipe is provided with an air blowing hole for blowing air onto the outer surface of the optical glass. The air blowing hole continuously blows air onto the outer surface of the optical glass, reducing the probability of dust or impurities adhering to the outer surface of the optical glass, thereby improving the cleanliness of the outer surface of the optical glass, extending the time for the optical glass to maintain good transparency, reducing the frequency of manual cleaning of the optical glass (such as stopping the machine for cleaning), saving labor costs, and increasing the normal working time of the counting and weighing machine.

[0036] 5. The present invention provides a grain counting and weighing machine, which also includes a combined weighing mechanism, which has the functions of weighing, combining weights and / or combining quantities for feeding, so that the material finally fed into the collecting hopper is closer to the specified material weight and / or the specified material quantity, thereby helping to improve the speed of subsequent packaging.

[0067] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0068] See Figures 2 to 4Specific embodiment 1 provides a grain counting and weighing machine, including a feeding mechanism 100, a receiving mechanism 200, a light source device 300, and a camera device 400. The feeding mechanism 100 includes a feeding cone 101 and a vibrating conveying device. The vibrating conveying device is connected to several vibrating conveying discs, which are arranged in a ring. The feeding ends of the several vibrating conveying discs converge at the center position, which corresponds to the lower part of the top cone 110 below the feeding cone 101. The discharging ends of the several vibrating conveying discs extend outward. The several vibrating conveying discs form a circular or annular vibrating feeding area, which increases the feeding volume and helps the material coming down from the feeding cone 101 to be radially dispersed and appropriately separated, so that the subsequent camera device 400 can obtain a more accurate feeding quantity, that is, improve the counting accuracy and counting efficiency.

[0069] In this embodiment 1, the vibrating conveying device includes a top cone 110 and a main vibrator 111 for driving the top cone 110 to vibrate, a first-stage vibrating plate 120 and a first-stage linear vibrator 121 for driving the first-stage vibrating plate 120 to vibrate, a second-stage vibrating plate 130 and a second-stage linear vibrator 131 for driving the second-stage vibrating plate 130 to vibrate. The feeding cone 101 is located above the top cone 110. The four edges of the top cone 110 correspond to the feeding end of the first-stage vibrating plate 120. The discharging end of the first-stage vibrating plate 120 corresponds to the feeding end of the second-stage vibrating plate 130. The material in the discharging end of the second-stage vibrating plate 130 falls to the receiving mechanism 200. The main vibrator 111, vibrating the top cone 110, evenly disperses the material coming down from the feeding cone 101, causing it to fall onto the feed end of the first vibrating disc around the perimeter. The first-stage linear vibration drives the first-stage vibrating disc 120 to vibrate, spreading the material out and distributing it evenly within the first-stage vibrating disc 120. The second-stage linear vibration drives the second-stage vibrating disc 130 to vibrate, further dispersing the material falling from the first-stage vibrating disc 120 to the second-stage vibrating disc 130, thus achieving appropriate separation of the material, improving the uniformity of material distribution, preventing material agglomeration, and ensuring that each piece of material can be captured by the optical path 301, improving the counting accuracy of the subsequent camera device 400, i.e., improving counting precision. The main vibrator 111 is connected to a weight sensor 112, which feeds back the weight of the material in the top cone 110 to the control unit. The control unit then controls the preceding feeding process device to add material into the top cone 110, indirectly controlling the material level in the top cone 110.

[0070] The control unit controls the material movement speed by controlling the vibration frequency of the first-stage linear vibrator 121 and the second-stage linear vibrator 131, which makes the material distribution more uniform and helps to improve the accuracy of counting particles.

[0071] The light source device 300 includes several light source modules (such as LED light source modules) arranged in a ring. The vibrating conveyor is located within the ring formed by the light source modules. The camera device 400 includes several counting cameras arranged in a ring below the vibrating conveyor. An optical path 301 is formed between the light source modules and the counting cameras. As the material from the discharge end of the several vibrating conveyor discs falls to the receiving mechanism 200, the material passes through the optical path 301, and the counting cameras determine the quantity of material discharged. At this time, the area of ​​the optical path 301 formed between the several counting cameras and the several light source devices 300 covers the area below the discharge end of all the second-stage vibrating discs 130, ensuring that the material falling from each second-stage vibrating disc 130 can be identified by the corresponding counting camera without any omissions, and improving the counting efficiency of the material.

[0072] In addition, several particle counting cameras are located below the vibrating conveyor within a ring formed by several light source modules, and the particle counting cameras are also arranged in a ring. The light from the light source modules shines on the corresponding particle counting cameras from the outside in, forming a light path 301, which is used to count the particles of material falling from the surrounding secondary vibrating discs 130. This arrangement effectively utilizes the space below the vibrating conveyor to arrange the particle counting cameras, resulting in a more rational spatial layout and a more compact overall structure for the particle counting weighing machine.

[0073] Preferably, the height of the light source module is located between the height of the second-stage vibrating plate 130 and the height of the counting camera. The light source module illuminates the counting camera in an inward and downward direction. The structure is more compact and the layout is more reasonable. When the operator touches the first-stage vibrating plate 120 and / or the second-stage vibrating plate 130, it will not interfere with the light path 301, that is, it will not interfere with the counting of materials, thus ensuring the accuracy of counting. Moreover, the operator will not bump into the counting camera, which protects the safety of the counting camera and effectively avoids the problem of inaccurate counting caused by the tilt or change of the angle of the counting camera. This also indirectly ensures the accuracy of counting.

[0074] The counting and weighing machine also includes a combination weighing mechanism 500, which is located between the feeding mechanism 100 and the receiving mechanism 200. The material passing through the optical path 301 is weighed by the combination weighing mechanism 500 and then combined by weight and / or quantity before being fed to the receiving mechanism 200, where it is finally discharged.

[0075] For example, the combined weighing mechanism 500 includes several counting hoppers 501 and several metering hoppers 502 for weighing materials. The counting hoppers 501 receive and count the materials falling from the corresponding second-stage vibrating plate 130. The metering hoppers 502 measure the weight of the materials, facilitating the control unit to combine the weights of the materials and release them after the weight is determined by a combination algorithm, and storing the materials before release. For example, the metering hoppers 502 use a weighing sensor (not shown in the attached figure) to measure the weight of the materials stored in the metering hoppers 502 in real time. The weighing sensor feeds the weight information back to the control unit, which also facilitates the control unit to control the amount of material fed into the feeding cone 101, ensuring the continuity and stability of the feeding.

[0076] If the counting and weighing machine only needs to combine the quantity of materials, it is not necessary to use a weighing sensor to weigh the material in the weighing hopper 502. In this case, the weighing hopper 502 is only used to temporarily store and combine the materials in the counting and receiving hopper 501. That is to say, the weighing hopper 502 is used to release the material after the control unit realizes the combination of materials to a specified quantity through the combination algorithm, and to store the material before releasing the material.

[0077] The receiving mechanism 200 includes a chute 201, a collecting cone 202, and a collecting hopper 203. Material from the discharge ends of several vibrating conveyor discs falls sequentially through the optical path 301 into corresponding counting hoppers 501 and metering hoppers 502. Material is then distributed sequentially to the chute 201, collecting cone 202, and collecting hopper 203 based on weight and / or quantity, with final discharge from the collecting hopper 203. Several counting hoppers 501 and several metering hoppers 502 are connected to a central column 601. The counting and weighing machine also includes a frame 600, on which the chute 201, collecting cone 202, and collecting hopper 203 are connected.

[0078] The grain counting and weighing machine also includes a control unit and a drive unit. The control unit controls the operation of the drive unit, the main vibrator 111, the first-stage linear vibrator 121, and the second-stage linear vibrator 131. The drive unit drives the operation of the receiving hopper, the metering hopper 502, and the collecting hopper 203. For example, a stepper motor is used to control the opening and closing of the hopper gate of each hopper to achieve accurate distribution of materials between the hoppers. This optimizes the structural layout and control method, ensuring the stability and reliability of the grain counting process. The grain counting camera feeds back the quantity of material fed to the control unit.

[0079] In this embodiment 1, the grain counting and weighing machine includes 14 sets of first-stage vibrating discs 120 and first-stage linear vibrators 121, 14 sets of second-stage vibrating discs 130 and second-stage linear vibrators 131, 14 second partitions 706; 7 light source modules and 7 grain counting cameras, 14 grain counting hoppers 501 and 14 metering hoppers 502. The first-stage vibrating discs 120, second-stage vibrating discs 130, grain counting hoppers 501 and metering hoppers 502 are all one-to-one, forming 14 material channels, which eventually converge into the same chute 201, the same collecting cone 202 and the same collecting hopper. The light source modules and grain counting cameras are one-to-one, forming 7 light paths 301, each light path 301 corresponding to 2 material channels. The material contact parts (such as the feeding cone 101, the top cone 110, the first-stage vibrating plate 120, the second-stage vibrating plate 130, the counting hopper 501, the metering hopper 502, the chute 201, the collecting cone 202, and the collecting hopper 203) are made of SUS304 stainless steel, which has good corrosion resistance and hygiene, making it suitable for packaging agricultural products such as corn seeds. The number of material channels can be adjusted according to actual needs, and is not limited to 14 material channels.

[0080] The control unit can be a PLC, employing a combination algorithm to calculate and combine the number of particles and / or the weight of materials in each material channel based on material information captured by the particle counting camera and / or weight information obtained from the metering hopper 502, thereby obtaining the material for specified packaging (e.g., specified quantity and / or specified weight), which helps improve the subsequent packaging speed. The control unit can be connected to a touch screen 630 for operation and display, allowing selection of different combination formulas, making it convenient to use and meeting the packaging needs of different types of materials (e.g., corn seeds).

[0081] The grain counting and weighing machine in this embodiment 1 has the following working modes:

[0082] 1. Multi-head scale weighing mode: When the multi-head scale weighing function is turned on, the weighing and measurement are completed according to the target weight. That is, the multi-head scale weighing function is realized by using several material channels, corresponding number of receiving hoppers 501 and weighing hoppers 502.

[0083] 2. Multi-head scale counting mode: When the multi-head scale counting function is enabled, for materials with small individual deviations and small quantities, the measurement is completed according to the target quantity. That is, everything else is the same as in mode 1. After obtaining the weight using the weighing hopper 502 of the weighing component (i.e., the combined scale weighing mechanism 500), the quantity of material in the hopper is determined by the set parameters to realize the multi-head scale counting function.

[0084] 3. Camera counting mode: When the counting camera function is enabled, the metering is completed by accurately counting, optimizing the combination calculation, and completing the measurement according to the target quantity. That is, the counting and metering function is realized by using several material channels, corresponding light source modules, counting cameras, corresponding counting hoppers 501 and metering hoppers 502.

[0085] 4. Weighing + Counting Mode: Enable the weighing function of the multi-head scale and the counting function of the particle camera. Simultaneously record the weight and quantity of material in each hopper. Based on the set target weight and target quantity, a combination algorithm is used to obtain a combination of discharge hoppers (such as metering hopper 502) that meets both weight and quantity requirements, thus realizing the weighing + counting function.

[0086] See Figures 5 to 7 In specific embodiment 2, a grain counting and weighing machine is provided. The difference between embodiment 2 and embodiment 1 is that the second-stage vibrating plate 130 is provided with several strip-shaped material moving troughs 132. The rear end of each material moving trough 132 corresponds to the feed end of the second-stage vibrating plate 130, and the front end corresponds to the discharge end of the second-stage vibrating plate 130. A separator 134 is also provided at the front end of the protrusion 133 between adjacent material moving troughs 132. After the material on the first-stage vibrating plate 120 falls into the second-stage vibrating plate 130, it will automatically fall into the corresponding material moving trough 132. Under the action of the second-stage linear vibrator 131, the second-stage vibrating plate 130 vibrates continuously, and the material in the material moving trough 132 moves forward along the straight material moving trough 132 until it reaches the discharge end of the second-stage vibrating plate 130 and then falls into the grain receiving hopper 501.

[0087] Because of the vibration of the second-stage vibrating plate 130, the material bounces and deviates from its falling trajectory the instant it falls from the discharge end of the second-stage vibrating plate 130. This may cause multiple pieces of material to overlap when passing through the optical path 301, and the obscured material cannot be identified by the counting camera, which is detrimental to the accurate counting of the material. The separating part 134 in this embodiment 2 can separate the material falling from the discharge end of the second-stage vibrating plate 130 at the moment of falling, avoiding the overlap of material passing through the optical path 301 as much as possible. This ensures that the material falling from each material moving trough 132 can be captured by the counting camera, ensuring the counting accuracy of the counting machine.

[0088] See Figures 8 to 10In specific embodiment 3, this embodiment 3 provides a counting and weighing machine. The difference between this embodiment 3 and the previous embodiments is that: a hollow central column 601 is provided on the frame 600, and a plurality of viewing windows 602 are provided on the central column 601. Optical glass 603 is covered on the viewing windows 602. An air pipe 604 is provided on the central column 601, and the air pipe 604 is provided with an air blowing hole 605 for blowing air onto the outer side of the optical glass 603. Preferably, the air pipe 604 is located directly above the optical glass 603, and the bottom of the air pipe 604 is provided with an air blowing hole 605. The air blowing hole 605 continuously blows air onto the outer side of the optical glass 603, reducing the probability of dust or impurities adhering to the outer side of the optical glass 603, which can improve the cleanliness of the outer side of the optical glass 603, prolong the time for the optical glass 603 to maintain good transparency, reduce the frequency of manual cleaning of the optical glass 603 (such as stopping the machine for cleaning), save labor costs, and also increase the normal working time of the counting and weighing machine.

[0089] Several counting cameras are located inside the central column 601. For example, the bottom of the central column 601 is provided with a base plate 608, and a mounting bracket 607 is provided on the base plate 608. The top of the mounting bracket 607 is ring-shaped, and seven counting cameras are evenly distributed on the top of the mounting bracket 607. The light path 301 of several light source modules located outside the central column 601 is received by the counting cameras through the optical glass 603.

[0090] Preferably, the top of the central column 601 is provided with a sealing cover 606. The sealing cover 606 and the central column 601 together enclose the second-stage linear vibrator 131, the first-stage linear vibrator 121 and the main vibrator 111, the counting camera and the mounting bracket 607 to form a sealed space. This prevents the counting camera from coming into contact with dust or flying debris, and also ensures the cleanliness and light transmission of the inner surface of the optical glass 603.

[0091] See Figures 11 to 19 In specific embodiment 4, a counting and weighing machine is provided. The difference between this embodiment 4 and the previous embodiments is that: the central column 601 is provided with a first auxiliary support frame 610 for supporting several light source modules. The first auxiliary support frame 610 is provided with several upwardly extending first support rods 611. The first support rods 611 are connected to a second auxiliary support frame 620 for fixing the feeding cone 101. The second auxiliary support frame 620 is connected to the material layer adjustment component 700. The second auxiliary support frame 620 can be moved up and down along the first support rods 611 to a specified height and then fixed to adjust the height of the feeding cone 101, thereby adjusting the height difference between the bottom of the first partition 102 and the top surface of the top cone 110, and also making it easier for the material to fall more evenly from the top cone 110 into the first-stage vibrating plate 120.

[0092] The second-stage linear vibrator 131, the first-stage linear vibrator 121, and the main vibrator 111 are mounted on the first auxiliary support frame 610.

[0093] The second auxiliary support frame 620 is provided with several downwardly extending second support rods 621; the material layer adjustment assembly 700 includes a fixing ring 701 and several mounting plates 702. The fixing ring 701 is provided with several screws 703 and several mounting brackets 704. The mounting brackets 704 are detachably connected to the second support rods 621. The screws 703 pass through the vertical strip holes 705 on the mounting plates 702 and are fixed by bolts 709 (such as wing bolts). By adjusting the mounting position of the mounting brackets 704 on the second support rods 621, the height of the fixing ring 701 is adjusted. Of course, the height adjustment of the second auxiliary bracket also affects the height of the fixing ring 701. The height of the fixing ring 701 affects the height of the second partition, that is, the height difference between the bottom of the second partition 706 and the bottom surface of the first-stage vibrating plate 120 can be adjusted to meet the needs of leveling different materials.

[0094] Alternatively, the mounting plate 702 can be moved up and down (i.e., the screws 703 and 709 move up and down within the vertical slot 705), and then the mounting plate 702 can be fixed to the fixing ring 701 (i.e., the bolts 709 on the screw 703) to adjust the height difference between the bottom of the second partition 706 and the bottom surface of the first-stage vibrating plate 120. This is convenient for meeting the needs of leveling different materials, and is especially suitable when the overall installation of the grain weighing machine is completed and the height difference between the bottom of the second partition 706 and the bottom surface of the first-stage vibrating plate 120 needs to be finely adjusted, or when different materials are changed and the height difference between the bottom of the second partition 706 and the bottom surface of the first-stage vibrating plate 120 is adjusted to meet the need for uniformly leveling the materials.

[0095] The mounting plate 702 connects to the second partition 706; each second partition 706 corresponds to a first-stage vibrating plate 120. The second partition 706 is used to flatten the material in the corresponding first-stage vibrating plate 120, making the material more evenly dispersed and ensuring that it can fall into the second-stage vibrating plate 130 one by one. If the second partition 706 is a single piece of partition 708, it may cause the material to be blocked and unable to move forward, resulting in the interruption of material movement in the corresponding first-stage vibrating plate 120. Therefore, the lower part of the second partition 706 is provided with several gaps 707, forming several partition pieces 708. The partition pieces 708 do not affect each other and are used to flatten the material at corresponding distances. Even if a small partition piece 708 blocks the material from moving forward, the other partition pieces 708 are not affected. The material in the material movement path corresponding to the other partition pieces 708 can still move normally, and the interruption of material movement in the corresponding first-stage vibrating plate 120 will not occur.

[0096] Preferably, a first partition 102 is connected to the bottom of the feeding cone 101. After the material from the feeding cone 101 falls to the top cone 110, the first partition 102 is used to scrape the material on the top cone 110 flat and prevent the material from agglomerating, so that the material falling from the top cone 110 to the feeding end of each first vibrating plate is more uniform, and the amount of material obtained by the first vibrating plate in each direction is basically the same.

[0097] See Figures 20 to 22 In specific embodiment 5, this embodiment 5 provides a counting and weighing machine. The difference between this embodiment 5 and the previous embodiments is that the counting and weighing machine also includes a combined weighing mechanism 500. The combined weighing mechanism 500 includes several counting hoppers 501, several metering hoppers 502 and several memory hoppers 503 for weighing materials. The receiving mechanism 200 includes a chute 201, a collecting cone 202 and a collecting hopper 203. After the material from the discharge end of several vibrating conveyor discs falls, it passes through the optical path 301 and falls sequentially into the corresponding counting hoppers 501, metering hoppers 502 and memory hoppers 503 (i.e., a three-layer hopper mode) for weight combination and / or quantity combination discharge to the chute 201, collecting cone 202 and collecting hopper 203, and finally discharged by the collecting hopper 203.

[0098] The "weight combination and / or quantity combination" refers to the control unit calculating and combining (e.g., adding values) the weight information fed back by each metering hopper 502 (i.e., the weighing sensor installed on the metering hopper 502) and the material quantity information fed back by each counting camera in the corresponding metering hopper 502, so that the total weight and / or total quantity of the material in several metering hoppers 502 is closer to or reaches the specified material weight and / or specified material quantity, and then discharging the material into the collection hopper 203 to help improve the speed of subsequent material packaging.

[0099] Several grain receiving hoppers 501, several metering hoppers 502 and several memory hoppers 503 are connected to the central column 601;

[0100] The drive unit drives the operation of the counting hopper 501, the metering hopper 502, the memory hopper 503, and the collection hopper 203.

[0101] In this embodiment 5, the particle counting and weighing machine adopts a three-layer hopper mode, adding a memory hopper 503, for example, 14 memory hoppers 503, located below the corresponding metering hoppers 502. In the original embodiment 1, the material was combined using a combination algorithm with one metering hopper 502 (for example, 14 metering hoppers 502). In this embodiment 5, a memory hopper 503 layer is added (for example, 14 memory hoppers 503, 14 metering hoppers 502 plus 14 memory hoppers 503, totaling 28 hoppers). In this case, the material is combined using a combination algorithm, the combination method is more diversified, the combination efficiency is higher, and the counting data or weight data after combination will be more accurate (for example, closer to the specified material quantity or specified material weight), improving the overall working efficiency and work quality of the particle counting and weighing machine.

[0102] In addition, when material is fed into the memory hopper 503 below, if the material in the metering hopper 502 is not temporarily selected for material combination, the metering hopper 502 can also temporarily feed the material into the memory hopper 503, so that the buffer head can receive the material from the next batch of receiving hopper 501 and measure the weight, update the combination selection options more quickly, and improve the efficiency of material combination.

[0103] In this embodiment 5, the metering hopper 502 is located above the memory hopper 503. The material in the metering hopper 502 can either fall into the memory hopper 503 or be directly discharged into the receiving mechanism 200. For example, when the material in the buffer hopper is selected by the control unit for material combination, the material in the metering hopper 502 does not need to fall into the memory hopper 503 (the memory hopper 503 may or may not contain material). The metering hopper 502 directly deflects to discharge the material, which falls directly into the receiving mechanism 200 through the space outside the memory hopper 503, thus improving the material combination efficiency.

[0104] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
