Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a dual-cell vehicle-mounted yield measurement system. Background Art

[0002] Field breeding trials are an important part of evaluating new breeding lines and their adaptability. During field breeding trials, yield evaluation of test plots is crucial, as it is a basic data source for determining the quality of breeding materials. Each test plot usually consists of a plot of land of a specific area, where a specific crop strain is planted. By analyzing the yield performance of the plot, researchers can determine the growth potential and stability of the strain under a specific growth environment. Current yield assessments usually require measuring multiple indicators such as total seed weight, moisture content, and bulk density, but existing yield measurement devices have a single function and can only obtain single data. Different instruments are required to measure other indicators separately, resulting in complex, time-consuming, and error-prone operations. In addition, the yield-measuring harvester needs to wait for the measurement to be completed after each harvest, and cannot achieve simultaneous harvesting and measurement, which seriously affects operating efficiency.

[0003] This experimental team has been browsing and studying a large amount of relevant records and materials on the relevant technologies of field breeding experiments for a long time. At the same time, it relies on relevant resources and conducts a large number of relevant experiments. After a lot of searches, it is found that existing prior arts such as CN114044375A, CN112394004B, CN110596152B and CN105181090B disclosed in the prior art are found. For example, the prior art discloses a large-scale grain depot grain bulk density automatic measurement system and measurement method, including a grain bin, a traveling frame, a grain taking device and a weighing device. The traveling frame is arranged in the grain bin to form a longitudinal and transverse walking track on the top of the grain bin. The grain taking device includes a motion mechanism and a container. The motion mechanism drives the container along the walking track to sample grain at at least five measuring points in turn. The weighing device includes a grain box and a weight sensor. The motion mechanism drives the container to sample into the grain box, and the weight sensor weighs the grain in the grain box 3-5 times, and calculates the average value, and then returns the measured average value to the main control terminal.

[0004] The present invention is made to solve the common problems in the field such as low yield measurement efficiency, cumbersome data measurement and unsuitability for field breeding experiments, etc. Summary of the invention

[0005] The purpose of the present invention is to propose a dual-cell vehicle-mounted production measurement system to address the deficiencies in the current field.

[0006] In order to overcome the shortcomings of the prior art, the present invention adopts the following technical solutions:

[0007] A dual-plot vehicle-mounted yield measurement system, comprising a mounting frame, a slide seat movably arranged at the bottom of the mounting frame and capable of being pulled and moved horizontally, a yield measurement module fixed on the slide seat for testing seeds, two grain inlet funnels respectively fixed at the top of the mounting frame for guiding harvested seeds into the yield measurement module, and a grain outlet funnel fixed at the bottom of the mounting frame for discharging measured seeds from the yield measurement module.

[0008] The mounting frame is a frame structure composed of a plurality of horizontal beams and vertical beams. The mounting frame is used to support the entire production measurement module, and through cooperation with the slide seat, the production measurement module can be pushed and pulled horizontally relative to the mounting frame. When the production measurement module is pushed and pulled out of the mounting frame with the cooperation of the slide seat, it is convenient for the operator to inspect, maintain and debug the production measurement module.

[0009] When the yield measuring module is pushed and pulled back into the mounting frame with the cooperation of the sliding seat, it can ensure that the yield measuring module is in an accurate measuring position, thereby realizing the measurement of seeds.

[0010] Furthermore, the yield measurement module includes a grain collecting unit arranged on the upper layer and capable of storing and releasing seeds from two different areas respectively, a weighing unit arranged at the bottom of the grain collecting unit and used for weighing the seeds in the same grain collecting bin, a multifunctional monitoring unit arranged under the weighing unit and used for monitoring the bulk density and moisture of the seeds, and a weighing outer cylinder surrounding the weighing unit and the monitoring unit.

[0011] Furthermore, the grain collecting unit includes a left grain collecting bin, a right grain collecting bin horizontally adjacent to the left grain collecting bin, a left grain unloading plate rotatably matched to the bottom of the left grain collecting bin via a rotating shaft, a right grain unloading plate rotatably matched to the bottom of the right grain collecting bin via a rotating shaft, a grain unloading cylinder having one end fixed to the outer wall of the left grain collecting bin and the other end fixed to the left grain unloading plate, and a grain unloading cylinder having one end fixed to the outer wall of the right grain collecting bin and the other end fixed to the right grain unloading plate.

[0012] Among them, the left grain collection bin and the right grain collection bin are used to store seeds of the two plots respectively, and the left grain collection bin and the right grain collection bin are collectively referred to as grain collection bins. The grain collection bin is a container that passes through from top to bottom. The opening at the top of the grain collection bin is used to receive the seeds flowing into the grain feeding funnel, and a grain feeding funnel is arranged above each grain collection bin for feeding materials toward the opening at the top of the grain collection bin. The grain unloading cylinder opens and closes the opening at the bottom of the grain collection bin by pushing the grain unloading plate.

[0013] Furthermore, the weighing outer cylinder is a structure that penetrates from top to bottom. The weighing outer cylinder is arranged as a whole below the grain collecting unit. The bottom of the weighing outer cylinder is fixedly installed on the sliding seat. The weighing outer cylinder provides an overall support and isolation environment for the total bin and the bulk weight bin.

[0014] Furthermore, the weighing unit includes a total bin located below the grain collecting unit and simultaneously mounted inside the weighing outer cylinder, a grain feed plate which can be horizontally moved and engaged with the bottom of the total bin through a guide track, a total removal plate which can be movably engaged with the bottom of the total bin, a total removal cylinder for controlling the movement of the total removal plate, two grain feed cylinders for controlling the horizontal movement of the grain feed plate, and at least two weighing sensors respectively arranged on the inner cylinder walls on both sides of the weighing outer cylinder, wherein the weighing sensors are used to measure the total weight of seeds in the total bin.

[0015] Furthermore, the main bin is a container that is connected from top to bottom, and the opening at the top of the main bin is used to receive seeds discharged from the left grain collecting bin and / or the right grain collecting bin. The closing control of the opening at the bottom of the main bin is achieved by the main removal cylinder and the main removal plate. The opening at the bottom of the main bin is partially opened by the movement of the grain feeding plate to transfer part of the seeds in the main bin to the multi-functional monitoring unit. The opening at the bottom of the main bin is fully opened by the movement of the grain feeding plate and the main removal plate.

[0016] Furthermore, the multifunctional monitoring unit includes a bulk density bin which is relatively arranged below the grain inlet plate and has a preset capacity specification, a bulk density cylinder whose top is fixed to the inner cylinder wall of the weighing outer cylinder through a corresponding fixing seat and whose bottom is bolted to the outer wall of the bulk density bin, a moisture measuring sensor for monitoring the moisture content of seeds arranged in the bulk density bin, a sensor mounting seat installed on the side of the bulk density bin and a bulk density sensor arranged on the sensor mounting seat for sensing and monitoring the weight changes of seeds in the bulk density bin, a grain outlet plate horizontally arranged at the bottom of the bulk density bin and a grain outlet plate cylinder for pushing the grain outlet plate to slide horizontally.

[0017] Furthermore, the cylinder body of the grain discharge plate cylinder is fixed to the outer wall of the bulk density bin by a bracket and bolts, and the piston rod end of the grain discharge plate cylinder is connected to the grain discharge plate by a hinge. When the grain discharge plate cylinder is extended or retracted, the grain discharge plate can be accurately pushed or pulled, thereby realizing the opening and closing control of the bottom opening of the bulk density bin by the grain discharge plate cylinder.

[0018] Furthermore, the bulk density cylinder is used to control the lifting and lowering movement of the bulk density bin relative to the weighing outer cylinder, thereby realizing the position adjustment of the bulk density bin and the total bin.

[0019] The beneficial effects achieved by the present invention are:

[0020] 1. The present invention integrates the measurement functions of total weight, bulk density and moisture content. All measurement steps are completed in the same device, reducing external interference problems that may be caused by switching between multiple devices. This integrated design reduces the cumbersome steps of multiple measurements, improves measurement efficiency, and simplifies the entire production measurement process.

[0021] 2. The present invention adopts a double-collection grain bin design, so that the yield measurement can be carried out in one plot at the same time, and the harvester can directly start harvesting the next plot without waiting for the yield measurement to be completed. This continuous yield measurement method greatly saves the yield measurement time, greatly improves the overall efficiency of the yield measurement, and improves the overall efficiency and data quality of the breeding experiment.

[0022] 3. An independent bulk density bin is set up. Before bulk density measurement, the grain feed plate is closed and a plane is cut out on the top surface of the bulk density bin to make the seed volume in the bulk density bin more accurate and ensure that the volume in the bulk density bin is fixed, so as to ensure that the measured bulk density data is more accurate, thereby effectively improving the reliability of the measurement.

[0023] 4. The action of the bulk density cylinder causes the bulk density bin to move downward and separate from the upper total bin. This movement brings about moderate vibration, which can make the seeds in the bulk density bin more evenly distributed. This can prevent the seeds from being too compact or too fluffy, thereby reducing the measurement error caused by uneven distribution and significantly improving the accuracy of moisture measurement.

[0024] 5. The design of the double-collection granary not only improves the efficiency of yield measurement, but also can adapt to the rapid switching between different plots. In this way, the system can better respond to changes in field conditions, making the yield measurement process more flexible and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is an explanation of the embodiments of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual sizes. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0036] Embodiment 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The present embodiment provides a dual-plot vehicle-mounted yield measurement system, which includes a mounting frame, a slide seat that is movably arranged at the bottom of the mounting frame and can be pulled horizontally, a yield measurement module fixed on the slide seat for testing seeds, two feed funnels respectively fixed to the top of the mounting frame for guiding harvested seeds into the yield measurement module, and a discharge funnel fixed to the bottom of the mounting frame for discharging measured seeds from the yield measurement module.

[0037] The mounting frame is a frame structure composed of a plurality of horizontal beams and vertical beams. The mounting frame is used to support the entire production measurement module, and through cooperation with the slide seat, the production measurement module can be pushed and pulled horizontally relative to the mounting frame. When the production measurement module is pushed and pulled out of the mounting frame with the cooperation of the slide seat, it is convenient for the operator to inspect, maintain and debug the production measurement module.

[0038] When the yield measurement module is pushed and pulled back into the mounting frame with the cooperation of the slide seat, it can ensure that the yield measurement module is in the accurate measurement position to measure the seeds.

[0039] 2. The dual-cell vehicle-mounted yield measurement system as described in claim 1 is characterized in that the yield measurement module includes a grain collection unit arranged on the upper layer and capable of storing and releasing seeds from two different areas respectively, a weighing unit arranged at the bottom of the grain collection unit and used for weighing the seeds in the same grain collection bin, a multifunctional monitoring unit arranged under the weighing unit and used for monitoring the bulk density and moisture of the seeds, and a weighing outer cylinder surrounding the weighing unit and the monitoring unit.

[0040] The grain collecting unit comprises a left grain collecting bin, a right grain collecting bin arranged horizontally adjacent to the left grain collecting bin, a left grain unloading plate rotatably matched with the bottom of the left grain collecting bin through a rotating shaft, a right grain unloading plate rotatably matched with the bottom of the right grain collecting bin through a rotating shaft, a grain unloading cylinder having one end fixed to the outer wall of the left grain collecting bin and the other end fixed to the left grain unloading plate, and a grain unloading cylinder having one end fixed to the outer wall of the right grain collecting bin and the other end fixed to the right grain unloading plate.

[0041] The left grain collection bin and the right grain collection bin are used to store seeds of two plots respectively, and are collectively referred to as grain collection bins. The grain collection bin is a container that is connected from top to bottom. The opening at the top of the grain collection bin is used to receive seeds flowing in from the grain feeding funnel, and a grain feeding funnel is arranged above each grain collection bin to feed the seeds toward the opening at the top of the grain collection bin. The grain unloading cylinder opens and closes the opening at the bottom of the grain collection bin by pushing the grain unloading plate.

[0042] The weighing outer cylinder is a structure that is connected from top to bottom. The weighing outer cylinder is arranged as a whole below the grain collecting unit. The bottom of the weighing outer cylinder is fixedly installed on the slide seat. The weighing outer cylinder provides an overall support and isolation environment for the total bin and the bulk weight bin, ensuring that the weight change in the total bin can be accurately measured and preventing external factors from interfering with the weighing.

[0043] The weighing unit comprises a total bin located below the grain collecting unit and sleeved inside the weighing outer cylinder, a grain feeding plate which can be horizontally moved and matched with the bottom of the total bin through a guide track, a total removal plate which can be movably matched with the bottom of the total bin, a total removal cylinder for controlling the movement of the total removal plate, two grain feeding cylinders for controlling the horizontal movement of the grain feeding plate, and at least two weighing sensors respectively arranged on the inner cylinder wall on both sides of the weighing outer cylinder, wherein the weighing sensor is used to measure the total weight of seeds in the total bin.

[0044] The main bin is a container that is connected from top to bottom, and the opening at the top of the main bin is used to receive seeds discharged from the left grain bin and / or the right grain bin. The closing control of the opening at the bottom of the main bin is achieved through the main removal cylinder and the main removal plate. The opening at the bottom of the main bin is partially opened by moving the grain feeding plate to transfer part of the seeds in the main bin to the multi-functional monitoring unit. The opening at the bottom of the main bin is fully opened by moving the grain feeding plate and the main removal plate.

[0045] The multifunctional monitoring unit is arranged below the main warehouse, and the multifunctional monitoring unit comprises a bulk density bin which is arranged relatively below the grain inlet plate and has a preset capacity specification, a bulk density cylinder whose top is fixed to the inner cylinder wall of the weighing outer cylinder through a corresponding fixing seat and whose bottom is bolted to the outer wall of the bulk density bin, a moisture measurement sensor arranged in the bulk density bin for monitoring the moisture content of seeds, a sensor mounting seat installed on the side of the bulk density bin and a bulk density sensor arranged on the sensor mounting seat for sensing and monitoring the weight change of seeds in the bulk density bin, a grain discharge plate arranged horizontally at the bottom of the bulk density bin and a grain discharge plate cylinder for pushing the grain discharge plate to slide horizontally, wherein the grain discharge plate is located at the bottom of the bulk density bin and directly covers the bottom opening of the bulk density bin, so as to control the discharge of seeds.

[0046] Among them, the cylinder body of the grain discharge plate cylinder is fixed to the outer wall of the bulk bin through a bracket and bolts, and the piston rod end of the grain discharge plate cylinder is connected to the grain discharge plate through a hinge. When the grain discharge plate cylinder is extended or retracted, it can accurately push or pull the grain discharge plate, thereby realizing the opening and closing control of the grain discharge plate cylinder on the bottom opening of the bulk bin.

[0047] The bulk density cylinder is used to control the bulk density bin to move up and down relative to the weighing outer cylinder, thereby realizing the position adjustment of the bulk density bin and the total bin. At the same time, the downward movement of the bulk density bin generates moderate vibration, which helps to make the seeds in the bulk density bin more evenly distributed, ensuring the accuracy of subsequent measurement data.

[0048] The grain feed plate opens under the control of the grain feed plate cylinder, and the seeds in the main bin enter the bulk density bin. When the bulk density bin is filled with seeds, the grain feed plate closes under the control of the grain feed plate cylinder, and the bulk density cylinder extends to move the bulk density bin down to the measuring position. At this time, the bulk density sensor starts to measure the weight of the seeds in the bulk density bin and calculates the bulk density data. At the same time, the moisture measurement sensor measures the moisture content of the seeds in the bulk density bin. After the measurement is completed, the main removal cylinder, the grain feed plate cylinder and the grain discharge plate cylinder respectively control the main removal plate, the grain feed plate and the grain discharge plate to open, and the seeds in the main bin and the bulk density bin fall into the grain discharge funnel.

[0049] The left granary and the right granary are used to store seeds from different plots respectively. When the harvester completes the harvesting of the first plot, the seeds will be immediately transported to the left granary. At the same time, the yield measurement module begins to measure the total weight, bulk density and moisture of the seeds in the left granary in sequence. During this process, the harvester can continue to harvest the next plot without waiting for the yield measurement to be completed. After the harvesting of the next plot is completed, the seeds will be temporarily stored in the right granary. After the measurement of the seeds of the previous plot in the left granary is completed, the yield measurement module then measures the total weight, bulk density and moisture of the seeds in the right granary in sequence. At this time, the harvester continues to start harvesting the seeds of the new plot.

[0050] By alternating the left grain collecting bin and the right grain collecting bin, continuous yield measurement operations are achieved, eliminating pauses caused by waiting for the completion of the yield measurement. Each time the seeds of a plot are measured in one of the grain collecting bins, the other grain collecting bin receives and stores seeds from the next plot, thereby achieving a seamless yield measurement process and significantly improving the yield measurement efficiency. The overall modular design of the present invention is easy to maintain and has strong adaptability, making the yield measurement process efficient, accurate and flexible.

[0051] The contents disclosed above are only preferred feasible embodiments of the present invention, and do not limit the protection scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention specification and drawings are included in the protection scope of the present invention. In addition, the elements therein can be updated as technology develops.
