Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1:

[0039] This utility model provides a multi-grain plot yield measurement device 1. Referring to Figures 1 to 11, the multi-grain plot yield measurement device 1 includes a feeding mechanism, a yield measurement mechanism 13, and a discharging mechanism 14.

[0040] The feeding mechanism, the production measurement mechanism 13, and the discharging mechanism 14 are arranged sequentially from top to bottom.

[0041] The feeding mechanism includes a feeding assembly 11 and a feeding switching assembly 12. The number of feeding assemblies 11 is the same as the number of grain plots to be tested, and the feeding ports of all feeding assemblies 11 are connected to the feeding switching assembly 12. The feeding switching assembly 12 enables the yield testing mechanism 13 to connect with the feeding port of any feeding assembly 11, so as to transport the grain in the feeding assembly 11 to the yield testing mechanism 13.

[0042] During operation, grains from different grain plots to be tested enter the corresponding feeding components 11. The feeding switching component 12 connects the feeding port of the designated feeding component 11 to the yield measuring mechanism 13, so that the grains in the feeding component 11 enter the yield measuring mechanism 13. After the yield measurement is completed, the feeding switching component 12 switches to another feeding component 11 to connect it with the yield measuring mechanism 13, and performs the yield measurement of the grains corresponding to the feeding component 11. In this way, the yield of grains from different grain plots to be tested can be measured sequentially and continuously, which not only has high yield measurement efficiency, but also significant yield measurement effect.

[0043] Example 2

[0044] Example 2 is based on Example 1:

[0045] As shown in Figures 1 to 11, the feeding assembly 11 includes a feeding barrel, the bottom of which is provided with a feeding port. The feeding mechanism includes a feeding switch assembly 15 located at the feeding port, which is used to open and close the feeding port of the feeding assembly 11.

[0046] The material feeding switch assembly 15 includes a first pull-out plate 151, a first guide member 152, and a first telescopic assembly 153.

[0047] The first pull-out plate 151 is slidably disposed on the first guide member 152 and located at the feed port. The first guide member 152 is configured as a guide rail and has a first guide groove on its side. The side of the first pull-out plate 151 is inserted into the first guide groove and slidably engaged with the first guide groove. The number of first guide members 152 is set to two, and the two opposite side parts of the first pull-out plate 151 are slidably engaged with the two first guide members 152 respectively.

[0048] The number of first telescopic components 153 is set to two, and the two first telescopic components 153 are symmetrically arranged on both sides of the first pull plate 151. A linkage plate is connected between the telescopic ends of the two first telescopic components 153. The linkage plate is fixedly arranged on the edge of the first pull plate 151. The telescopic movement of the first telescopic components 153 can drive the first pull plate 151 to move, thereby blocking or opening the discharge port.

[0049] The first telescopic component 153 can be a pneumatic telescopic component, an electric telescopic component, or a hydraulic telescopic component, with a pneumatic telescopic component being preferred.

[0050] As an optional implementation, the feeding switching assembly 12 includes a switching barrel 121 and a flip-on / off assembly 122. The number of switching barrels 121 and flip-on / off assemblies 122 is the same as the number of feeding assemblies 11. The top opening of the switching barrel 121 is located below the corresponding feeding port. The flip-on / off assembly 122 is located at the bottom outlet of the switching barrel 121 and is used to block or open its top outlet.

[0051] The flip-on / off assembly 122 includes a flip plate 1221 and a flip-telescopic assembly 1222. The flip plate 1221 is rotatably mounted on the switching barrel 121. Specifically, the flip plate 1221 is rotatably mounted at the position of the bottom opening of the switching barrel 121 via a hinge shaft.

[0052] The fixed end and telescopic end of the flip telescopic assembly 1222 are respectively hinged to the outer wall of the switching barrel 121 and the flip plate 1221.

[0053] When the telescopic end of the flip telescopic assembly 1222 is in the retracted position, the flip plate 1221 blocks the bottom outlet of the switching barrel 121. The telescopic end of the flip telescopic assembly 1222 extends, pushing the flip plate 1221 to rotate away from the switching barrel 121, thereby opening the bottom outlet of the switching barrel 121.

[0054] As an optional implementation, the feeding mechanism includes a feeding hopper 16 connected above the feeding hopper, and the feeding hopper 16 is connected to the threshing device 5 through a grain conveying pipeline.

[0055] During operation, after the threshing device 5 threshes the grain, it is transported to the feed hopper 16 through the grain conveying pipeline and then enters the discharge hopper.

[0056] As an optional implementation, the yield measurement mechanism 13 includes a weighing mechanism and a moisture and weight measurement mechanism.

[0057] The weighing mechanism includes a weighing barrel 131 and a first weight detection component 132. The weighing barrel 131 is provided with a weighing cavity 1311, which is used to hold the grain to be tested. The first weight detection component 132 is connected to the weighing barrel 131 and is used to detect the weight of the grain in the weighing cavity 1311.

[0058] The moisture and bulk density measuring mechanism includes a constant volume measuring cylinder 133, a moisture detection component 134, and a second weight detection component 135. The constant volume measuring cylinder 133 is provided with a constant volume measuring chamber 1331 that is connected to the weighing chamber 1311. The moisture detection component 134 is disposed on the constant volume measuring cylinder 133 and is used to detect the moisture content of the grain in the constant volume measuring chamber 1331. The second weight detection component 135 is connected to the constant volume measuring cylinder 133 and is used to detect the weight of the grain in the constant volume measuring chamber 1331.

[0059] During yield measurement, the feeding switching component 12 transports the grain from the corresponding feeding component 11 to the weighing chamber 1311. The first weight detection component 132 detects the weight of the grain in the weighing chamber 1311. Then, some of the grain enters the constant volume measuring chamber 1331 from the weighing chamber 1311 and fills the constant volume measuring chamber 1331. The moisture detection component 134 detects the moisture content of the grain in the constant volume measuring chamber 1331. At the same time, the second weight detection component 135 detects the weight in the constant volume measuring chamber 1331. Since the volume of the constant volume measuring chamber 1331 is constant, the volume of grain filling the constant volume measuring chamber 1331 is constant. The ratio of the weight detected by the second weight detection component 135 to the weight of the constant volume measuring chamber 1331 is the bulk density of the grain to be tested.

[0060] In the actual testing process, the grains from all grain plots were sequentially sent to the yield testing facility 13 for yield testing.

[0061] This invention, through the cooperation of the weighing mechanism and the moisture and bulk density measuring mechanism, can not only effectively and accurately collect the weight, moisture and bulk density of grains, resulting in significant yield measurement, but also achieve continuous collection of the weight, moisture and bulk density of the grains to be measured, making yield measurement highly efficient.

[0062] As an optional implementation, support eaves 1312 are provided on the two opposing walls of the weighing bucket 131, and the first weight detection component 132 includes a first weight sensor, with the weight sensor provided at the bottom of each support eaves 1312.

[0063] By employing multiple primary weight sensors and weighing at multiple points, local errors caused by uneven grain distribution or mechanical vibration can be automatically offset, thereby improving the accuracy and stability of weighing.

[0064] As an optional implementation, the top of the weighing hopper 131 is open to form a feed inlet, which is located below the feeding switching component 12. All grains falling from the bottom opening of the switching hopper 121 can enter the weighing chamber 1311. The bottom of the weighing hopper 131 is provided with a transition port, and a first on / off component 136 for controlling the connection or disconnection of the transition port is provided at the position of the transition port.

[0065] The constant volume measuring cylinder 133 is disposed on the bottom side of the weighing barrel 131. The constant volume measuring chamber 1331 is connected to the weighing chamber 1311 through a transition port. The bottom of the constant volume measuring cylinder 133 is provided with a discharge port. A second on / off component for controlling the connection or disconnection of the discharge port is provided at the position of the discharge port.

[0066] Both the first on / off assembly 136 and the second on / off assembly 137 are configured as horizontal pull-out on / off assemblies. The horizontal pull-out on / off assembly includes a second pull-out plate 1361, a second telescopic assembly 1362, and a second guide member 1363. The telescopic end of the second telescopic assembly 1362 is connected to the corresponding second pull-out plate 1361 and can drive the second pull-out plate 1361 to move. Each second pull-out plate 1361 is provided with at least one second telescopic assembly 1362. The second guide member 1363 is configured as a second guide rail. A second guide groove is provided on the second guide rail. The side part of the second pull-out plate 1361 is inserted into the second guide groove and slides in cooperation with the second guide groove.

[0067] The structure of the horizontal pull-out switch assembly is the same as that of the material feeding switch assembly.

[0068] The first on / off component also has the function of sorting grains. By moving its second pull plate 1361, it scrapes and flattens the grains, thereby sorting them so that the grains can just fill the constant volume measurement cavity 1331, ensuring that the volume of the grains is consistent with the volume of the constant volume measurement cavity 1331, and the bulk density measurement effect is significant.

[0069] As an optional implementation, the moisture and bulk density measuring mechanism includes a vertical telescopic component 138, which may be a pneumatic telescopic component, a hydraulic telescopic component, or an electric telescopic component.

[0070] A support frame 1332 is fixedly installed on the volume measuring cylinder 133, and the support frame 1332 moves synchronously with the volume measuring cylinder 133.

[0071] The fixed end of the vertical telescopic component 138 is fixedly mounted on the bracket on the outer wall of the weighing barrel 131, and the telescopic end of the vertical telescopic component 138 is connected to the support frame 1332.

[0072] The second weight detection component 135 includes a second weight sensor, which is disposed at the bottom of the support frame 1332.

[0073] In the initial state, the telescopic end of the vertical telescopic component 138 is in the retracted state, the support frame 1332 is in the upper position, the constant volume measuring cylinder 133 is connected to the weighing barrel 131, and the first on / off component 136 and the second on / off component 137 are both in the open state.

[0074] During yield measurement, after the first weight detection component 132 weighs the grain in the weighing barrel 131, the first on / off component 136 opens, and the grain in the weighing chamber 1311 falls into the volume measurement chamber 1331 until the volume measurement chamber 1331 is full. At this time, the first on / off component 136 closes, and the telescopic end of the vertical telescopic component 138 extends, causing the support frame 1332 and the volume measurement barrel 133 to move to the lower position. The second weight detection component 135 weighs the grain in the volume measurement barrel 133, and the bulk density can be obtained by the ratio of the weight to the volume of the volume measurement barrel 133. At the same time, the moisture detection component 134 detects the moisture content of the grain in the volume measurement barrel 133. After the measurement is completed, the telescopic end of the vertical telescopic component 138 retracts, and the support frame 1332 and the volume measurement barrel 133 move to the upper position. After that, the first on / off component 136 and the second on / off component 137 open simultaneously to discharge the grain.

[0075] As an optional implementation, the moisture detection assembly 134 is provided with a moisture sensor, which is fixedly mounted on the wall of the constant volume measuring cylinder 133, and the detection end of the moisture sensor is located inside the constant volume measuring cavity 1331.

[0076] The moisture sensor can effectively collect the moisture content of the grain to be tested within the constant volume measurement cavity 1331.

[0077] As an optional implementation, the discharge mechanism 14 includes a discharge hopper 141, which is located below the production measuring mechanism 13. The bottom discharge port of the discharge hopper 141 is connected to the grain bin 6 through a collection pipeline.

[0078] As an optional implementation, the multigrain plot yield measurement device 1 also includes a support mechanism 17, on which the feeding mechanism, the yield measurement mechanism 13 and the discharge mechanism 14 are arranged sequentially from top to bottom.

It not only has significant harvesting and yield measurement effects, but also high harvesting and yield measurement efficiency.

The header device 3, the conveying device 4, the threshing device 5, the grain bin 6, and the multi-grain plot yield measuring device 1 are all mounted on the vehicle body 2.

[0086] The vehicle body 2 includes a frame for mounting various devices, and a driver's cab mounted on the frame, wherein a central control device in the driver's cab is used for controlling the various devices.

[0087] The header device 3 includes multiple stalk-pulling header mechanisms 31 arranged in sequence. An isolation body 32 is provided between two adjacent stalk-pulling header mechanisms 31. All stalk-pulling header mechanisms 31 correspond one-to-one with all grain plots. The structure of the stalk-pulling header mechanism 31 is existing technology and will not be described in detail.

[0088] The input end of the conveying device 4 is connected to the header device 3, and the output end of the conveying device 4 is connected to the threshing device 5. The conveying device 4 includes multiple conveying mechanisms arranged in sequence, and the conveying mechanisms adopt feeding augers and chain rake lifters.

[0089] The threshing device 5 includes multiple threshing mechanisms arranged in sequence. The threshing mechanism adopts an axial flow threshing device. The number of the threshing mechanism, the conveying mechanism, the stem-pulling header mechanism 31, the feeding assembly 11, and the grain plot to be tested are the same. The stem-pulling header mechanism 31 is connected to the corresponding threshing mechanism through the corresponding conveying mechanism. The threshing mechanism is connected to the corresponding feeding assembly 11 through the corresponding grain conveying pipeline.

[0090] The discharge mechanism 14 is connected to the grain bin 6 through the collection pipeline. The grain bin 6 is used for collecting grain. Both the grain conveying pipeline and the collection pipeline use wind power to convey the grain.

[0091] In actual use, as the vehicle body 2 moves, the header device 3 simultaneously harvests grains from multiple parallel grain plots. The conveying device 4 transports the grains from different grain plots to the corresponding threshing mechanisms. After threshing, the threshing mechanisms transport the grains to the corresponding feeding components 11. The feeding switching component 12 and the yield measuring mechanism 13 cooperate with each other to measure the yield of the grains in each feeding component 11 in sequence, and the discharge mechanism 14 transports them to the grain bin 6.
