Description

Technical Field

[0001] This invention relates to the field of intermittent yield measurement and quantitative packaging technology in small-scale breeding, and specifically to a device for intermittent yield measurement and quantitative packaging in small-scale breeding. Background Technology

[0002] In the harvesting stage of plot breeding, the harvested grains need to be measured and packaged quantitatively. However, traditional breeding machinery is bulky, making it inconvenient to collect grains quantitatively from each plot. Furthermore, traditional beam boxes are prone to seed residue, leading to seed mixing between different plots. This directly affects seed purity and yield measurement accuracy, and makes it impossible to process materials from different plots independently in batches.

[0003] Therefore, there is an urgent need for a plot breeding intermittent yield measurement and quantitative packaging device that can ensure seed purity and yield measurement accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a device for intermittent yield measurement and quantitative packaging in small-scale breeding to solve the technical problems mentioned in the background art.

[0005] This invention provides an intermittent yield measurement and quantitative packaging device for plot breeding, installed at the tail of a plot breeding harvester, comprising: The grain conveying device has an intermittent opening and closing structure integrated at the inlet; The intermittent yield measurement device includes a grain conveying bin and a chain drive mechanism. The chain drive mechanism enables the grain conveying bin to reach the receiving station for receiving grains output from the grain conveying device, the yield measurement station for measuring the weight of grains in the bin, and the unloading station for emptying the grains in the bin. The bag-supporting device includes end claws that can be driven to open and a feeding funnel for receiving grains poured out of the grain silo; The load-bearing platform, located below the bag-supporting device, is used to provide bottom load-bearing support for the breeding bags; The bag-opening and packing device includes a first packing component and a second packing component, the second packing component including: The bag-taking grippers are arranged longitudinally opposite each other. The bag-taking grippers on both sides are used to clamp the breeding bags output by the first packaging component and move them to the bottom of the end support claws. The bag mouth side grippers are arranged laterally opposite each other. The bag mouth side grippers on both sides can move laterally towards each other and clamp the front and rear sides of the breeding bag mouth below the end support claw. One of the bag mouth side grippers can move longitudinally under the action of the misalignment drive source so that the two bag mouth side grippers are longitudinally misaligned. After the two bag mouth side grippers are longitudinally misaligned, they move laterally in opposite directions. At the same time, the bag picking grippers on both sides move longitudinally towards each other and cooperate with the end support claw to open the breeding bag mouth to receive the grains leaking out of the feeding funnel. A double-rod drawstring winding shaft is used to seal and pack the breeding bags; the packed breeding bags are then sent out via a conveyor belt.

[0006] Optionally, the intermittent opening and closing structure integrated at the inlet of the grain conveying device includes an iris device for controlling the entry and exit of materials; the iris device can alternately open and close according to the harvesting rhythm of the plot, and realize the intermittent interruption and flow control of grain materials by changing the diameter.

[0007] Optionally, the conveying structure includes: Drive sprocket, A closed chain engages with the drive sprocket; the grain storage bin is suspended on the closed chain via a transport platform. An intermittent wheel, with its rotating output end connected to the drive sprocket, is capable of controlling the drive sprocket to perform intermittent stepping drive on the closed chain. A weighing sensor is installed at the yield measurement station to measure the weight of grains carried by the grain transport bins arriving at the yield measurement station.

[0008] Optionally, multiple grain storage bins are provided at equal intervals on the closed chain, and the spacing between the grain storage bins corresponds to the step spacing of the closed chain.

[0009] Optionally, the bag-supporting device includes: A fixed frame is provided, and the feeding funnel is fixed to a fixed base within the fixed frame; each of the end support claws is hinged to the bottom end of the fixed base. A bag-supporting drive rod is fitted around the outer periphery of the feeding hopper and can slide up and down along the outer wall of the feeding hopper. The bag-supporting drive rod is connected to the end support claw through a linkage mechanism. When the grains output from the feeding funnel need to be received through the breeding bag, the bag support drive rod slides down along the outer wall of the feeding funnel and can radially open the end support claws outward. The opened end support claws penetrate deep into and tightly open the opening of the breeding bag, so that the opening of the bag remains in a stable tension state. When the seeds in the breeding bag reach the preset target weight value, the bag support drive rod slides upward along the outer wall of the feeding funnel, which can cause the end support claw to retract and reset inward.

[0010] Optionally, the first packaging component is a rolling bag feeding mechanism.

[0011] Optionally, the second packaging component further includes: The system comprises mutually orthogonal transverse main slide rails and longitudinal slide rails. A main slider is slidably mounted on the transverse main slide rail. A telescopic drive rod is mounted on the main slider via a rotating shaft. The telescopic end of the telescopic drive rod is connected to a flipping arm. The rotating shaft is connected to a flipping lateral drive source. The bag-picking gripper is located at the end of the flipping arm and is driven by a gripper drive source; the main slider and the flipping arm work together to drive the bag-picking gripper to alternate between the bag-picking station below the first packaging assembly and the bag-opening station below the bag-supporting device; the bag-picking gripper is used to reach the bag-picking station to clamp the breeding bag output by the first packaging assembly when the main slider moves to the rightmost position and the flipping arm rotates 180°; the bag-picking gripper is used to reach the bag-opening station to transfer the breeding bag to the underside of the end support claw when the main slider and the flipping arm are reset; The first and second bag-opening slide rails are parallel to each other and are slidably mounted on the longitudinal slide rail and the main slider, respectively. The first and second bag-opening slide rails can move in opposite directions or in the same direction laterally. Each of the first and second bag-opening slide rails has a bag-mouth side gripper driven by a side gripper drive source on its opposite side. Under the drive of the misalignment drive source, the first and second bag-opening slide rails can move relative to each other in the longitudinal direction, so that the opposite bag-mouth side grippers are longitudinally misaligned and intersected, thereby performing a shearing initial opening on the breeding bag opening. After the bag opening side gripper is longitudinally misaligned, the side gripper drive source drives the bag opening side gripper to clamp towards the center. The first bag opening slide rail and the second bag opening slide rail retract as a whole so that the two bag opening side grippers move in opposite directions in the lateral direction. At the same time, the telescopic drive rod retracts inward to drive the bag taking grippers on both sides to move in opposite directions in the longitudinal direction, thereby completing the complete opening of the bag opening in both the lateral and longitudinal directions. One of the bag opening side grippers can move longitudinally under the action of the misalignment drive source to make the two bag opening side grippers longitudinally misaligned; after the two bag opening side grippers are longitudinally misaligned, they move laterally in opposite directions, while the bag taking grippers on both sides move longitudinally towards each other to cooperate with the end support claw to open the breeding bag opening to receive the grains leaking out of the feeding funnel; after the feeding material is filled, the flipping lateral drive source drives the flipping arm to flip so that the bag taking grippers move downwards for fine adjustment, while the load-bearing platform at the bottom carries the breeding bag full of grain material and moves downwards synchronously until the drawstring bag opening line of the breeding bag and the double rod drawstring winding shaft are adjusted to a horizontal parallel position.

[0012] Optionally, the second packaging component further includes: A sliding block is arranged longitudinally on a longitudinal slide rail. A lifting drive source is located on the side of the sliding block, and a lifting arm is connected to the top of the lifting drive source. The double-bar drawstring winding shaft is mounted on the lifting arm. The sliding block performs a horizontal pushing motion from the inside out on the longitudinal slide rail, causing the double-bar drawstring winding shaft to extend forward. The drawstring portion of the breeding bag passes through the gap between the two parallel winding bars of the double-bar drawstring winding shaft and advances parallel to a position slightly beyond the bag opening. At this point, the outer bag-removing claw releases, while the inner bag-removing claw remains clamped. Subsequently, the double-bar drawstring winding shaft rotates at high speed around its own axis, continuously winding the inward drawstring of the breeding bag and forcefully pulling it outward, achieving a tight sealing and packaging of the breeding bag opening.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses an intermittent yield measurement and quantitative packaging device for small-plot breeding. During operation, the grains harvested by the small-plot breeding machine enter the intermittent weighing and yield measurement mechanism through a material collection mechanism. Intermittent dynamic weighing and yield data collection are performed by batch or small plot segment. After yield measurement, the material falls into the automatic quantitative packaging mechanism below, where a bagging and storage mechanism enables real-time automatic material feeding and quantitative packaging without a grain silo. This invention highly integrates yield measurement and packaging functions, effectively solving the problems of large size in traditional breeding machinery and seed mixing caused by traditional grain bins. While achieving "immediate collection, measurement, and packaging" of small-plot materials, it ensures yield measurement accuracy and seed purity, greatly improving the automation level and efficiency of small-plot breeding harvesting operations.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] Example 1 1. Overall equipment and core process flow like Figure 1 This device features a compact, silo-less design, directly fixed to the tail of the small-plot breeding harvester via bolts or a suspension mechanism. The seeds produced by the harvester are first introduced by the grain conveying device 7. An iris device is integrated at the inlet of the grain conveying device 7, and the material flow is intermittently interrupted by controlling the opening and closing rhythm of the iris. After the material enters the intermittent yield measuring device 1 for independent weighing of each plot, it is discharged downwards into the bag-supporting device 2. During this process, the bag-opening and packing devices 3 and 4 work together to move the breeding bags from the first packing assembly 4 through the second packing assembly 3 to directly below the bag-supporting device 2. Throughout the bag opening, filling, and sealing process, the load-bearing platform 5 provides reliable support to the bottom of the bag. Finally, the packaged and sealed breeding bags fall onto the bottom conveyor belt 6 and are discharged, achieving continuous automated operation.

[0018] 2. Structure and working principle of intermittent yield measurement device 1 Combined with appendix Figure 2The intermittent yield measurement device 1 specifically comprises a drive sprocket 101, an intermittent wheel 102, a grain hopper 103, a transport platform 104, a closed chain 107, and a weighing sensor 108. The intermittent wheel 102 serves as a power distribution and indexing control element, and its rotational output end is connected to the drive sprocket 101. The chain 107 is wound around the drive sprocket 101 and the driven wheel to form a horizontal circulation loop. Several transport platforms 104 carry bucket-shaped grain hoppers 103 on the outer side of the chain 107. A weighing sensor 108 is fixedly installed at a specific position at the top of the entire circulation path.

[0019] The specific working cycle of this intermittent yield measurement device is as follows: 1. Intermittent receiving stage: Grains are intermittently fed from the upper grain conveying device into the grain silo 103, which is currently in the receiving position, according to the same time interval or small segment.

[0020] 2. Stepping Conveying and Synchronous Feeding Stage: After the material in the bin is collected, the intermittent wheel 102 rotates precisely one revolution, driving the drive sprocket 101 to rotate at a preset angle through the indexing transmission, thereby driving the entire chain 107 to move forward one station. At this time, the grain hopper 103, which is full of grain, is pushed to the position of the weighing sensor 108 by the transport platform 104, completing an independent production data collection; at the same time, the next empty grain hopper 103 synchronously cycles to the receiving station to start receiving the next batch of grain.

[0021] 3. Tilting and Unloading Stage: With the next rotation of the intermittent wheel 102, the weighed grain bin 103 continues to move forward along the transport platform 104 and changes position at the turning point. The grain material inside the bin automatically falls downward due to gravity and enters the bag-supporting device 2 below. It should be noted that the turning point uses a closed inclined plate to guide the grain to the bag-supporting device 2 below.

[0022] 3. Structure and working principle of bag support device 2 Combined with appendix Figure 3 The bag-supporting device 2 specifically includes: a feeding funnel 201, a bag-supporting drive rod 202, a fixed frame 203, a linkage mechanism 204, a fixed base 205, and end support claws 206. The entire mechanism is supported and enclosed by the outer fixed frame 203. The feeding funnel 201 is located at the central axis. The fixed base 205 is fixedly installed inside the frame. The bag-supporting drive rod 202 is fitted around the outer periphery of the feeding funnel 201 and can slide up and down along its outer wall. Several end support claws 206 are arranged in a ring at the bottom outlet of the feeding funnel 201 and form a linkage transmission pair with the bag-supporting drive rod 202 through the intermediate linkage mechanism 204.

[0023] The complete workflow of this bag-supporting device in a single operation is as follows: 1. Material introduction and positioning detection: After the yield measurement is completed, the seeds fall into the feeding funnel 201 by gravity. At the same time, when the control system detects that the bag opening and packaging device has transported the breeding bags to be filled to the predetermined station, it triggers the bag opening action.

[0024] 2. Mechanical linkage bag-opening stage: The drive source drives the bag-opening drive rod 202 to move downwards vertically. During this process, the bag-opening drive rod 202 presses against the linkage mechanism 204, driving the bottommost end support claws 206 to open radially outwards. The opened end support claws 206 penetrate and tightly open the opening of the breeding bag, maintaining a stable tension at the bag opening, and then the seeds in the funnel smoothly fall into the breeding bag.

[0025] 3. Reset Phase: When the weight of the seeds in the breeding bag reaches the preset target weight value, the system issues a reset command, driving the bag-supporting drive rod 202 to move upwards in the opposite direction. At this time, the linkage mechanism 204 drives the end support claw 206 to retract inwards and reset, disengaging from the breeding bag opening.

[0026] 4. The linkage mechanism of the second packaging component 3 and the fully automated packaging process Combination Figure 4 The second packaging component 3 specifically includes: a first bag-opening slide rail 301, a longitudinal slide rail 302, a lifting drive source 303, a misalignment drive source 304, a side clamp drive source 305, a bag opening side clamp 306, a lifting arm 307, a clamp drive source 308, a middle frame 309, a flipping / lateral drive source 310, a second bag-opening slide rail 311, a main slider 312, a transverse main slide rail 313, a flipping arm 314, a pushing slider 315, a telescopic drive rod 316, a bag-removing clamp 317, a stop block 318, and a double-rod drawstring winding shaft 319. In this embodiment, the breeding bag used is a drawstring mesh breeding bag, and in its initial state, the sealing drawstring is arranged facing inwards towards the device.

[0027] A single complete work cycle of the second packaging component 3 consists of the following five stages: 1. Precise Bag Removal Stage: The main slider 312 moves along the transverse main slide rail 313 to the rightmost boundary. The lateral drive source 310 drives the flipping arm 314 to rotate 180 degrees around the axis below the transverse main slide rail 313, so that the bag-removing gripper 317 accurately reaches directly below the first packaging component 4. Accompanied by the rolling bag supply of the first packaging component 4, the breeding bag is delivered and precisely positioned between the paired bag-removing grippers 317. The gripper drive source 308 then drives the bag-removing grippers 317 to close and clamp the two sides of the bag opening, completing the initial bag removal.

[0028] 2. Multi-component linkage misalignment bag opening stage: The main slider 312 and the flipping arm 314 move synchronously in opposite directions. The main slider 312 moves to the left to reset, and the flipping arm 314 flips 180 degrees below the transverse main slide rail 313 to reset, horizontally transporting the clamped breeding bag to the bag opening station below the bag supporting device 2. After positioning, the first bag opening slide rail 301 and the second bag opening slide rail 311 move simultaneously, driving the bag opening side grippers 306 on both sides and the corresponding components on the opposite side to close, clamping the breeding bag opening. Subsequently, the misalignment drive source 304 triggers the relative sliding of the first bag opening slide rail 301 and the second bag opening slide rail 311, causing the paired side grippers 306 to misalign in a plane, and the breeding bag opening is initially opened by shearing force.

[0029] Next, multiple components perform synchronized compound motion: the side clamping drive source 305 drives the bag opening side clamping claw 306 to clamp towards the center, the first bag opening slide rail 301 and the second bag opening slide rail 311 retract as a whole, and at the same time, the telescopic drive rods 316 on both sides retract inward, thereby completing the full opening of the bag opening in both the horizontal and vertical directions; as an exemplary embodiment, the telescopic drive rod 316 adopts a push rod cylinder; during this process, the bag picking claws 317 on both sides move outward in accordance with the opening of the bag under the drive of the telescopic drive rod 316, to ensure that the bag opening is taut and fully open. At this time, the bag supporting device 2 above smoothly cuts into the bag opening to complete the secondary mechanical bag supporting and unloading.

[0030] 3. Filling Displacement and Height Alignment Stage: After the material is filled, the lateral drive source 310 drives the telescopic drive rod 316 and the flipping arm 314 to flip, so that the bag-removing gripper moves downward for fine adjustment. At the same time, the load-bearing platform 5 at the bottom carries the breeding bag filled with seed material and moves downward synchronously until the drawstring opening of the breeding bag and the double-rod drawstring winding shaft 319 are adjusted to a horizontal parallel position.

[0031] 4. Double-bar rotating drawstring tightening and packaging stage: The push slider 315 performs a horizontal pushing motion from the inside to the outside on the longitudinal slide rail 302, driving the double-bar drawstring winding shaft 319 to extend forward. The drawstring part of the breeding bag opening precisely passes through the gap between the two parallel winding bars of the double-bar drawstring winding shaft 319, and advances parallel to a position slightly beyond the bag opening. At this time, the outer bag-removing claw 317 releases, while the inner clamping component continues to hold the bag. Subsequently, the double-bar drawstring winding shaft 319 rotates at high speed around its own axis, continuously winding the inward drawstring of the breeding bag and forcefully pulling it outward, achieving a tight-sealed packaging of the breeding bag opening.

[0032] 5. Lifting, Unwinding, and Discharging Stage: After the binding is completed, the lifting drive source 303 drives the lifting arm 307 to rise vertically upward, causing the double-rod rope winding shaft 319 to detach from the tightened rope loop from above. Subsequently, all clamps and grippers in the system are released and reset, and the packaged breeding bags fall onto the bottom conveyor belt 6 under their own gravity and are smoothly discharged from the device, thus completing the harvesting and packaging process for the entire small section.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The intermittent yield measurement and quantitative packaging device for plot breeding according to claim 7, characterized in that, The second packaging component (3) also includes: A sliding block (315) is arranged longitudinally on the longitudinal slide rail (302). A lifting drive source (303) is provided on the side of the sliding block (315). A lifting arm (307) is connected to the top of the lifting drive source (303). The double-bar rope winding shaft (319) is located on the lifting arm (307). The sliding block (315) performs a horizontal pushing motion from the inside to the outside on the longitudinal slide rail (302), driving the double-bar rope winding shaft (319). Extending forward, the drawstring portion of the breeding bag mouth passes through the gap between the two parallel winding rods of the double-rod drawstring winding shaft (319) and advances parallel to a position slightly beyond the bag mouth; at this time, the outer bag-removing claw (317) releases, while the inner bag-removing claw (317) continues to hold the bag. Subsequently, the double-rod drawstring winding shaft (319) rotates at high speed around its own axis, continuously winding the inward drawstring of the breeding bag and forcefully pulling it outward, thereby achieving a tight-sealed packaging of the breeding bag mouth.
