Abstract
Description
Technical Field
[0001] This application relates to the field of threshing technology, and in particular to a rebound component, an in-situ threshing device and method for rice and wheat. Background Technology
[0002] Field sampling yield measurement is a basic method used before crop harvesting. Rice and wheat ears are cut according to a certain grid or representative sampling points, threshed, weighed, and moisture content is measured. This is used to estimate yield per unit area, verify variety performance, and calibrate remote sensing inversion models.
[0003] Typically, technicians cut double-row samples on-site, put them into net bags and take them back to their base. Then, they put the rice and wheat crops into a tabletop electric threshing machine, manually pick out the threshed grains, and finally weigh them.
[0004] However, tabletop threshers are large and heavy, making them impossible to move to the field. Only rice and wheat samples can be taken in the field. The rice and wheat samples are easily scattered or lost during round-trip transportation. The subsequent threshing, cleaning, and collection must be completed in stages, which is a discrete and time-consuming process, making it impossible to achieve threshing in one go in the field. Summary of the Invention
[0005] Based on this, it is necessary to provide a rebound component for rice and wheat threshing, an in-situ rice and wheat threshing device and method to address the above-mentioned technical problems. The threshing device integrates threshing and cleaning functions, occupies little space, and eliminates the need to transport traditional threshing machines and cleaning machines for decentralized operations, enabling rice and wheat to be threshed in situ.
[0006] In a first aspect, the present invention provides a rebound assembly for rice and wheat threshing. The rebound assembly is disposed on an installation assembly, the installation assembly including an installation cavity with a feed inlet, the rebound assembly including an opening and closing member and a rotating unit, the opening and closing member being rotatably connected to the inner wall of the installation cavity and having an initial position and an open position, the rotating unit including a rotating part and an elastic member connected to the rotating part, the rotating part being rotatably disposed in the installation cavity and passing through the installation cavity and being fixedly connected to the opening and closing member, the rotating part being used to drive the opening and closing member to rotate from the initial position of blocking the feed inlet to the open position of opening the feed inlet, the elastic member being twisted to generate elastic potential energy when the elastic potential energy is released, and the elastic member being used to drive the rotating part to rotate in the opposite direction so that the opening and closing member rotates to the initial position.
[0007] In one embodiment, the rotating part includes a rotating member and an operating member rotatably connected to the mounting cavity. One end of the rotating member passes through the mounting cavity and is fixedly connected to the opening and closing member, and the other end is fixedly connected to the operating member. An elastic member is sleeved on the rotating member, with one end fixedly connected to the rotating member and the other end fixedly connected to the mounting cavity by means of a connecting member. The operating member drives the rotating member and the opening and closing member to rotate synchronously, so that the elastic member is twisted to generate elastic potential energy. When the elastic potential energy is released, the elastic member can drive the rotating member to rotate in the opposite direction, so as to drive the opening and closing member to rotate to the initial position.
[0008] In a second aspect, the present invention provides an in-situ rice and wheat threshing device, which includes the aforementioned rebound component and separation component. The separation component is rotatably disposed in the mounting cavity to separate rice and wheat grains from impurities in the rice and wheat crop, and to output the impurities to the outside of the mounting component along a preset path.
[0009] In one embodiment, the separation component includes a threshing section rotatably connected to the mounting cavity and an airflow section connected to the threshing section. The threshing section is used to separate rice and wheat grains from impurities in the rice and wheat crop when rotating. The airflow section can rotate synchronously with the threshing section and generate airflow to discharge impurities from the mounting cavity along a preset path.
[0010] In one embodiment, the separation assembly further includes a screening section disposed within the mounting cavity and below the threshing section, for filtering rice and wheat grains output from the threshing section.
[0011] In one embodiment, the threshing section includes a drive shaft and a separating plate. The drive shaft is rotatably connected to the inner wall of the mounting cavity to form two pivot points. The drive shaft rotates along the axis formed by the two pivot points. The separating plate is circumferentially spaced along the drive shaft and rotates synchronously with the drive shaft.
[0012] In one embodiment, the airflow section includes a first airflow component and a second airflow component. The first airflow component is rotatably disposed in the mounting cavity, and the second airflow component is fixedly disposed in the mounting cavity and attached to the surface of the first airflow component. The first airflow component has a penetrating first airflow region, and the second airflow component has a penetrating second airflow region. When the first airflow component rotates, it changes the relative position of the first airflow region with respect to the second airflow region, so that at least a part of the second airflow region is in communication with the first airflow region. Thus, outside air passes through the first airflow region, the second airflow region and the interior of the mounting cavity in sequence, and blows impurities along a preset path to the impurity discharge port of the mounting cavity.
[0013] In one embodiment, the second airflow region includes a plurality of airflow holes, and the number of airflow holes located in the first airflow region changes when the first airflow component rotates.
[0014] In one embodiment, the rice and wheat in-situ threshing device further includes a collection component, which includes two collection containers, both of which are detachably mounted on the mounting cavity and used to collect rice and wheat grains separated by the separation component.
[0015] In a third aspect, the present invention provides a rice and wheat threshing method, the method comprising the following steps: opening the feed inlet and pressing the rice and wheat crop onto the feed inlet; driving the separation component to rotate, so that the rice and wheat grains and impurities are separated from each other, and the impurities are output to the outside of the installation component along a preset path.
[0016] The technical effects of this invention are: First, the threshing device of the present invention integrates threshing and cleaning functions, occupies little space, and completes threshing in the field, eliminating the need to transport traditional threshing machines and cleaning machines for decentralized operations.
[0017] Secondly, by separating the rice and wheat crops through three processes—threshing, airflow purging, and sieving—the impurity content of the rice and wheat grains is reduced, thereby increasing the purity of the grains and improving the accuracy of detecting the moisture and weight of the rice and wheat grains.
[0018] Third, the rotary handle and torsion spring of the rebound assembly adopt an integrated design. The torsion spring is built into the inner cavity of the rotary handle. The entire assembly can be pulled out and the torsion spring can be replaced simply by removing the handle. There is no need to open the installation cavity. Moreover, dust and other impurities in the installation cavity will not enter the interior of the rotary handle, which extends the maintenance cycle of the rebound assembly and simplifies the on-site replacement steps.

[0034] See Figure 1 , Figure 2This diagram illustrates a rice and wheat in-situ threshing device according to an embodiment of this application. The rice and wheat in-situ threshing device 100 includes an installation component 10, a separation component 20, a detection component 30, a display module 40, and a rebound component 50. The installation component 10 includes an installation cavity 11, an operating handle 12, and an installation base 13. The installation cavity 11 is disposed on the installation base 13, and the top of the installation cavity 11 is provided with a feed inlet 111. The operating handle 12 is disposed on the side of the installation cavity 11 facing away from the feed inlet 111, and the extension direction of the operating handle 12 is away from the feed inlet 111. When holding the operating handle 12, the feed inlet 111 will not be blocked. The center of gravity of the entire threshing device 100 is on the operating handle 12, reducing operator fatigue. The separation component 20 is rotatably disposed in the mounting cavity 11, used to separate rice and wheat grains from impurities in the rice and wheat crop when rotating, and to output the impurities to the outside of the mounting component 10 along a preset path; the detection component 30 is disposed on the separation component 20, used to detect the grain parameters of the rice and wheat grains and the position parameters of the threshing device 100, and to calculate the yield index of the rice and wheat crop based on the parameters; the display module 40 is disposed on the outside of the mounting cavity 11, including a display screen electrically connected to the detection component 30. The feeding, threshing, impurity removal, and detection systems are integrated into one compact unit. The handheld operating handle 12 can be moved to any point in the field, and the rice or wheat crop is inserted into the feed inlet 111. The rebound component 50 presses the rice or wheat crop firmly into the feed inlet 111. The separation component 20 can discharge impurities such as husks, stems, and leaves to the area around the plant roots, forming a covering layer, reducing water evaporation and replenishing organic matter. No additional collection bag is required, achieving zero consumables and zero waste green operation. The detection component 30 can detect the rice or wheat grains separated by the separation component 20 to obtain grain parameters and location parameters, which are immediately displayed on the screen. There is no need to move traditional threshers, cleaners, and benchtop metering equipment for decentralized operations. Moreover, multiple tests can be performed at the same location, improving the accuracy of yield indicators.
[0035] In other embodiments, the threshing device 100 can omit the detection component 30 and the display module 40. After the rice and wheat are threshed in place, the clean rice and wheat grains are put into a bag or a small collection box and taken back indoors for precise detection using a desktop near-infrared spectroscopy instrument, moisture meter or balance. At the same time, the raw data such as threshing time, location and estimated yield recorded by the threshing device 100 in the field are synchronized to a mobile phone, tablet or cloud via Bluetooth in real time. If the signal is lost, it is cached locally first and automatically retransmitted after entering the network coverage area. Because the screen and sensors are eliminated, the weight and power consumption of the whole machine are reduced, making it more suitable for lightweight yield measurement operations with long distance and multiple locations.
[0036] In other embodiments, at least a portion of the surface of the mounting cavity 11 is provided with an observation window, which is a transparent structure, allowing for convenient observation of the rice and wheat crops inside the mounting cavity.
[0037] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the spring-loaded assembly 50 includes an opening / closing member 51 and a rotating unit 52. The opening / closing member 51 is rotatably connected to the side wall of the mounting cavity 11 via the rotating unit 52 and can rotate relative to the mounting cavity 11, thereby enabling the opening / closing member 51 to open or block the feed inlet 111. In this embodiment, the opening / closing member 51 includes an opening / closing door panel, which is arc-shaped and its outer periphery is in contact with the edge line of the feed inlet 111. The rotating unit 52 includes a rotating part 521 and an elastic member 522 connected to the rotating part 521. The rotating part 521 is rotatably disposed in the mounting cavity 11 and passes through the mounting cavity 11. Cavity 11 is fixedly connected to opening and closing member 51. Elastic member 522 includes torsion spring. The rotation of rotating part 521 is directly converted into the angle change of opening and closing member 51: When rotating part 521 rotates, rotating part 521 drives opening and closing member 51 to open feed port 111. Opening and closing member 51 is in the open position. At the same time, elastic member 522 generates elastic potential energy during the rotation of rotating part 521. When rotating part 521 is released, the elastic potential energy accumulated by elastic member 522 is released. At this time, opening and closing member follows rotating part 521 to rotate in the opposite direction until opening and closing member 51 rotates to the initial position of blocking feed port 111.
[0038] Specifically, the rotating part 521 in this embodiment consists of a rotating component 5211, a connecting component 5212, and an operating component 5213: the rotating component 5211 is a rotating shaft that passes through the mounting cavity 11, with its inner end rigidly connected to the opening / closing component 51 and its outer end extending into the operating component 5213; a torsion spring is sleeved on the rotating shaft, with one end of the torsion spring fixedly connected to the rotating shaft and the other end fixed to the outer wall of the mounting cavity 11 via the connecting component 5212, which is movably sleeved on the rotating shaft and fixedly connected to the outer wall of the mounting cavity 11; the operating component 5213 is a rotating handle, which is hollow inside to form an inner cavity, and the torsion spring is placed in this inner cavity, realizing an integrated design of the rotating handle and the torsion spring. The operator rotates the handle to drive the rotating part 521 and the opening / closing component 51 to rotate synchronously, thereby opening the feed port 1. 11. At this time, according to the "Technical Specifications for Yield Measurement" of the Ministry of Agriculture and Rural Affairs, take a 1m or 1m double-row sample section, cut off the rice and wheat and insert it into the feed inlet 111. During the rotation, one end of the torsion spring rotates with the shaft, while the other end is kept stationary by the connector 5212, forming a fixed fulcrum, so that the torsion spring is twisted and stores elastic potential energy. After the rotation handle is released, the torsion spring releases elastic potential energy, driving the opening and closing part 51 to rotate in the opposite direction to the initial position of blocking the feed inlet 111, and pressing the rice and wheat crops at the feed inlet 111. Since the torsion spring is built into the inner cavity of the rotation handle, it is only necessary to remove the rotation handle to pull out the whole and replace the torsion spring. There is no need to open the installation cavity 11, and the dust and other impurities in the installation cavity 11 will not enter the interior of the rotation handle, effectively extending the maintenance cycle of the rebound component 50 and simplifying the on-site replacement steps.
[0039] like Figure 2 , Figure 5As shown, the separation assembly 20 includes a threshing section 21 rotatably connected to the mounting cavity 11, an airflow section 22 connected to the threshing section 21, and a screening section 23 disposed in the mounting cavity 11 and located below the threshing section 21. The threshing section 21 disclosed in this embodiment includes a drive shaft 211 and a separation plate 212. The airflow section 22 is connected to the drive shaft 211 and is used to generate airflow along the drive shaft 211. The drive shaft 211 is rotatably connected to the inner wall of the mounting cavity 11 to form two pivot points. The drive shaft 211 rotates along the axis formed by the two pivot points. Each separation plate 212 is provided with separation teeth 2121 on its edge and a through guide hole 2122. The drive module 60 drives the drive shaft 211 to rotate. The drive module 60 can be a rotary motor installed at one end of the drive shaft 211. The rotary motor is fixedly installed in the mounting cavity 11. During the rotation, the separating teeth 2121 comb and beat the rice and wheat crops, causing the rice and wheat grains to separate from impurities. The guide hole 2122 weakens the radial airflow generated by the separating plate 212 when the drive shaft 211 rotates, reducing the interference to the airflow section 22, making the airflow in the airflow section 22 along the drive shaft 211 more concentrated, thereby more smoothly blowing the impurities to the discharge port of the mounting cavity 11, while the rice and wheat grains fall to the screening section. The screening section 23 includes a screening container 231 and a filter screen 232 installed on the screening container 231. The filter screen 232 separates the rice and wheat grains again.
[0040] In other embodiments, the screening section 23 can be omitted, and the threshing section 21 and the airflow section 22 work together to complete the two-step separation of "threshing-blowing". The impurities are directly blown by the airflow section 22 along the drive shaft 211 to the discharge port of the mounting cavity 11, and the rice and wheat grains do not need to be screened again.
[0041] like Figure 1 , Figure 2 and Figure 6 As shown, specifically, the airflow section 22 includes a first airflow component 221, a second airflow component 222, and a wind source component 223. In this embodiment, the first airflow component 221 is a first airflow disk, the second airflow component 222 is a second airflow disk, and the wind source component 223 is a fan. The fan is fixedly mounted on the drive shaft 211 and rotates synchronously with it, providing airflow along the drive shaft 211. The first airflow disk is rotatably supported on the inner wall of the mounting cavity 11, and has several first airflow regions 2211 circumferentially arranged therein. The second airflow disk is fixed inside the mounting cavity 11 and fits against the end face of the first airflow disk, and has a second airflow region 2221 circumferentially arranged by multiple airflow holes. By rotating the first airflow disk, the first airflow disk rotates relative to the second airflow disk with the drive shaft 211. The effective flow area increases or decreases with the number of airflow holes. Outside air enters the mounting cavity 11 sequentially through the first airflow regions 2211 and the airflow holes, thereby adjusting the airflow size of the fan in real time.
[0042] In other embodiments, the first airflow component 221 is connected to the drive shaft 211 via a limiting structure. The limiting structure is an electromagnetic clutch connected to the control module. The control module can be any circuit or device capable of receiving angle signals and outputting on / off signals, such as a microcontroller, PLC, DSP, ARM processor, FPGA, SOC, or even a simple switch circuit with wireless remote control functionality. As long as it has at least one digital output pin to drive the electromagnetic clutch coil, it can serve as the control module in this embodiment. The active end of the electromagnetic clutch is fixedly connected to the drive shaft 211, and the driven end is fixedly connected to the first airflow disk. The rotary motor drives the drive shaft 211 to rotate, the electromagnetic clutch engages, and the first airflow disk rotates relative to the second airflow disk with the drive shaft 211. The effective flow area increases or decreases with the number of airflow holes. When the control module determines that the first airflow disk has rotated to a preset angle, the control module controls the electromagnetic clutch to disengage, the first airflow disk stops rotating, the fan continues to rotate, and the outside air enters the mounting cavity 11 sequentially through the first airflow area 2211 and the airflow holes, blowing impurities toward the discharge port 112.
[0043] In other embodiments, the first airflow region 2211 and the second airflow region 2221 can both be an arc-shaped region. As long as the first airflow component 221 rotates relative to the second airflow component 222, the relative position of the first airflow region 2211 relative to the second airflow region 2221 can be changed, thereby changing the connection area of the first airflow region 2211 and the second airflow region 2221, thus achieving the airflow adjustable function.
[0044] like Figure 1 , Figure 2 and Figure 7As shown, the detection component 30 is installed on the inner wall of the screening container 231 to detect the particle parameters of rice and wheat grains and the position parameters of the threshing device 100, and to calculate the yield index of rice and wheat crops based on the parameters. Specifically, the detection component 30 includes a first detection unit 31 disposed in the screening container 231 and a second detection unit 32 disposed on the mounting cavity 11. The first detection unit 31 includes a first detection element 311 for detecting the moisture content M (%) of rice and wheat grains and a second detection element 312 for detecting the weight W (g) of rice and wheat grains. In this embodiment, the first detection element 311 is a moisture sensor and the second detection element 312 is a weight sensor. The second detection unit 32 includes a third detection element (not shown) for detecting the latitude and longitude of the threshing device and a fourth detection element for detecting the levelness of the threshing device. In this embodiment, the third detection element is a positioning sensor and the fourth detection element is a level. The level outputs the pitch and tilt angles θ in real time and corrects the weight value W with cosθ, eliminating false weight gain on slopes. It can maintain weighing accuracy in continuous operation without stopping the machine for manual leveling, reducing the error in yield per acre and realizing high-precision automatic yield measurement in complex terrains such as slopes and terraces. Based on the yield index, yield (kg / mu) = [W(g)·cosθ / A(m)]×666.7×(100M) / 86.5×10 -3 In the calculation formula: W—weight of rice and wheat grains; θ—inclination angle of the level; M—moisture content; A—sampling area calculated from latitude and longitude.
[0045] like Figure 1 , Figure 2 and Figure 7 As shown, the rice and wheat in-situ threshing device 100 also includes a collection component 70, which includes two collection containers. Both collection containers are detachably installed on the mounting cavity 11. The openings of the two collection containers are aligned with the outlet of the screening container 231. The screening container 231 is provided with a partition plate 2311. By pulling the partition plate 2311, rice and wheat grains can enter the collection container.
[0046] In other embodiments, there may be only one collection container, or only a single container, which can also be quickly disassembled and unloaded to meet the needs of small plots or lightweight production measurement.
[0047] This embodiment also discloses an in-situ rice and wheat threshing system. The in-situ rice and wheat threshing system includes the above-mentioned threshing device 100 and a control module (not shown). Each drive module 60 is installed in the mounting cavity 11 and electrically connected to the corresponding separation component 20. It outputs speed or start / stop signals as needed. The control module communicates with the drive module 60, the detection component 30 and the display module 40 through a CAN bus or wireless mesh, and can read latitude, longitude, level, moisture content and weight parameters in real time. Based on the latitude and longitude coordinates output by the positioning sensor, the working field is automatically divided into several minimum management units according to the preset grid side length or artificial vector boundary, and a plot code is generated. The control module sends start / stop, speed, and operation period commands to the corresponding drive module 60 based on the plot number. The drive module 60 automatically adjusts the speed and duration of the drive motor according to the plot number. Each threshing device 100 can operate independently in sequence, or multiple threshing devices 100 can operate in parallel. The control module can obtain the data of one or more threshing devices 100 and stitch them together to form a yield distribution map. The display module 40 simultaneously visualizes the yield curve, moisture content cloud map, and equipment status. For example, if the plot code is 003, the screening duration is 25 seconds, and the speed is 800 rpm, the corresponding threshing device 100 will perform matching actions within this boundary. After the operation, the data of each plot code is transmitted back and stitched together to form a yield distribution map.
[0048] like Figure 8 As shown, this embodiment also discloses a method for threshing rice and wheat. Combined with the threshing device 100 described above, the threshing method includes the following steps: S801: Open the feed inlet and press the rice and wheat crops firmly against the feed inlet; When the rotating part 521 rotates, it drives the opening and closing part 51 to open the feed inlet 111. The opening and closing part 51 is in the open position, and the rice and wheat crops are inserted into the feed inlet 111. At the same time, the elastic element 522 generates elastic potential energy during the rotation of the rotating part 521. When the rotating part 521 is released, the elastic potential energy accumulated by the elastic element 522 is released. At this time, the opening and closing part rotates in the opposite direction with the rotating part 521 until the opening and closing part 51 rotates to the initial position of blocking the feed inlet 111. At this time, the opening and closing part 51 presses the rice and wheat crops tightly at the feed inlet 111.
[0049] S802: Drive the separation component 20 to rotate, so that the rice and wheat grains and impurities are separated from each other, and the impurities are output to the outside of the mounting component 10 along a preset path.
[0050] Driven by the drive module 60, the drive shaft 211 rotates. During the rotation, the separating teeth 2121 comb and beat the rice and wheat crops, causing the rice and wheat grains to separate from impurities. The guide hole 2122 weakens the radial airflow generated by the separating plate 212 when the drive shaft 211 rotates, reducing interference with the airflow section 22 and making the airflow in the airflow section 22 along the drive shaft 211 more concentrated, thereby blowing the impurities more smoothly to the discharge port of the mounting cavity 11. The rice and wheat grains fall to the screening section. The screening section 23 includes a screening container 231 and a filter screen 232 set on the screening container 231. The filter screen 232 separates the rice and wheat grains again.
[0051] In addition, the threshing method also includes the following steps: S803: Detect the grain parameters of rice and wheat grains and the position parameters of the threshing device 100, and calculate the yield index of the rice and wheat crops based on the parameters. Further, S803 includes the following steps: S8031: Obtain moisture content, weight, latitude and longitude, and levelness.
[0052] The detection assembly 30 includes a first detection unit 31 disposed in the screening container 231 and a second detection unit 32 disposed on the mounting cavity 11. The first detection unit 31 includes a first detection element 311 for detecting the moisture content M (%) of rice and wheat grains and a second detection element 312 for detecting the weight W (g) of rice and wheat grains. In this embodiment, the first detection element 311 is a moisture sensor and the second detection element 312 is a weight sensor. The second detection unit 32 includes a third detection element (not shown) for detecting the latitude and longitude of the threshing device 100 and a fourth detection element for detecting the levelness of the threshing device. In this embodiment, the third detection element is a positioning sensor and the fourth detection element is a level.
[0053] S8032: Based on the land parcel number, the control module sends at least one control command among start / stop, speed, and operating period to the corresponding drive module 60.
[0054] Based on the latitude and longitude coordinates output by the positioning sensor, the working field is automatically divided into several smallest management units according to the preset grid side length or artificial vector boundary, and a plot code is generated. The control module sends start / stop, speed and working period instructions to the corresponding drive module 60 based on the plot number. The drive module 60 automatically adjusts the speed and duration of the drive motor according to the plot number. The display module 40 simultaneously visualizes the yield curve, moisture content cloud map and equipment status. For example, if the plot code is 003, the screening duration is 25s and the speed is 800 rpm, the corresponding threshing device will perform matching actions within the boundary. After the operation, the data of each plot code is sent back and stitched together to form an accuracy yield distribution map.
[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
