Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and particularly relates to a harvester for the intercropping mode of corn and sorghum sudanense and its working method. Background Art

[0002] In recent years, with the adjustment of the agricultural industry, the production of the agricultural industry has been changed according to the demand for agricultural products. More and more land has been planted with cash crops instead of food crops, and intercropping of crops has been realized in some areas. For example, the Chinese invention patent with the application number CN201810658056.4 discloses a sustainable planting mode based on the intercropping of wheat and corn with green manure sown in between; when harvesting corn, a common harvester is used for harvesting, but the utilization rate of corn is very high, while the utilization rate of its straw is very low. Some farmers need a large amount of corn straw silage feed. After the corn straw is crushed alone, the feeding effect on livestock is not good, and usually other green plants need to be mixed for feeding. Therefore, new intercropping methods have gradually emerged. For example, in the prior art, the Chinese invention patent with the application number CN202210574403.1 discloses an ecological planting method of sorghum sudanense and corn intercropping, which improves the land utilization rate by intercropping sorghum sudanense and corn, increases the planting area of sorghum sudanense, and improves the product quality and yield; therefore, the planting method of spring wheat intercropped with corn and then sorghum sudanense replanted after the spring wheat is harvested has emerged one after another.

[0003] The Chinese utility model patent with the application number CN200520114682.5 discloses a new type of corn straw silage feed harvesting and crushing machine; specifically, it discloses a method of hanging the cutting table in front of the walking vehicle. The cutting table includes a cutting and crushing device, a discharging device, an aggregate device and a blowing device, which combines the processes of harvesting, feeding and crushing of corn straw into one step and completes them instantaneously. The structure is simple and it is not convenient for large-scale application; however, in the intercropping mode, the corn straw and sorghum sudanense are mixed together after harvesting.

[0004] However, mixing sorghum sudanense and corn straw to make silage is an effective feed production method, which can improve the nutritional value and digestibility of the feed. On the premise of mixing, sorghum sudanense and corn straw need to be mixed according to a certain weight ratio, and the above-mentioned scheme cannot meet the requirement of mixing in proportion. Summary of the Invention

[0005] Based on this, the present application provides a harvester for the intercropping mode of corn and sorghum sudanense to solve the problem that sorghum sudanense and corn straw cannot be mixed in proportion.

[0032] Please refer to Figures 1 to 9, this application provides a harvester for the intercropping mode of corn and sorghum sudanense, which is used to harvest the first crop and the intercropped second crop and proportionally mix them. It includes: a vehicle body 10, on which a frame is provided, and the vehicle body 10 is used to travel along a preset direction; a biomass acquisition component, which is used to acquire the biomass characteristic information of the first crop and the second crop; a material distribution control component, including a biomass evaluation module and an instruction output module. The biomass evaluation module is used to evaluate the biomass of the first crop and the second crop based on the biomass characteristic information; the instruction output module is used to issue a control instruction based on the biomass of the first crop and the second crop, and configure an actuator. The actuator includes a first crop harvesting component 100, a second crop harvesting component 200 and a mixing bin 410. A first channel 121 is provided at the discharge end of the first crop harvesting component 100, and the discharge end of the first channel 121 is connected to the mixing bin 410; a material distribution component is provided at the discharge end of the second crop harvesting component 200. The material distribution component includes a second channel 221, a third channel 222 and a material distribution gate 300 provided at the feed ends of the second channel 221 and the third channel 222. The second channel 221 is connected to the mixing bin 410, and a temporary storage bin 420 is provided at the discharge end of the third channel 222; the material distribution gate 300 has a first position and a second position and can be switched between the first position and the second position. When the material distribution gate 300 is in the first position, the second channel 221 is opened and the third channel 222 is closed; when the material distribution gate 300 is in the second position, the second channel 221 is closed and the third channel 222 is opened; and the control actuator of the material distribution gate 300 is electrically connected to the instruction output module.

[0033] Specifically, the vehicle body 10 may be, but is not limited to, a small harvester, a tractor, etc. The biomass evaluation module may be, but is not limited to, a combination of one or more identification devices such as a light transmittance detector, a height detector, a density detector, a scanner, etc. The biomass characteristic information of the first crop (for example, corn) includes density, height, number of roots, etc. The biomass characteristic information of the second crop (for example, sorghum sudanense) also includes the corresponding density, height, number of roots, etc. The biomass evaluation module is respectively arranged at the front end of the vehicle body 10 according to its function (the front end is the end where the vehicle body 10 moves along the predetermined direction).

[0034] The first crop harvesting component 100 includes a first cutting member 110 and a first crushing member 120. The second crop harvesting component 200 includes a second cutting member 210 and a second crushing member 220. Both the first cutting member 110 and the second cutting member 210 adopt the cutting devices at the front end of the corn straw harvester (both are publicly known in the prior art). In the drawings, it is an embodiment. The structures of the first cutting member 110 and the second cutting member 210 are the same, including a fixed cutting knife, a sliding cutting knife and an auxiliary roller. The sliding cutting knife slides horizontally along the direction perpendicular to the traveling direction of the vehicle body 10 and can be driven by means of a telescopic cylinder or the like. The first crop or the second crop enters the position of the fixed cutting knife, and the sliding cutting knife cuts it by sliding. At the same time, the auxiliary roller arranged above the fixed cutting knife rotates in the clockwise direction to guide the cut first crop or second crop and make it enter the first crushing member 120 or the second crushing member 220 along the direction of rotation of the auxiliary roller for crushing. In this application, taking the harvesting of corn straw and sorghum sudanense as an example, the first cutting member 110 is used to harvest corn straw, and the second cutting member 210 is used to cut sorghum sudanense. After the first cutting member 110 finishes cutting, the corn straw is transported to the first crushing member 120 for crushing through a conveyor belt. After the second cutting member 210 finishes cutting, the sorghum sudanense is transported to the second crushing member 220 for crushing through a conveyor belt. Both the conveyor and the conveyor belt are devices with transmission functions and are provided in the existing corn straw harvesters. The specific structures and specific settings thereof will not be elaborated here.

[0035] The first shredding member 120 is used to shred the corn straw cut by the first cutting member 110, and the second shredding member 220 is used to shred the sorghum-sudangrass cut by the second cutting member 210. The first shredding member 120 and the second shredding member 220 adopt the shredding system in the existing corn straw harvester shredder (the corn straw harvester shredder has been disclosed and is prior art). The attached drawing shows an embodiment. The first shredding member 120 and the second shredding member 220 have the same structure, including an upper shredding cutter and a lower shredding cutter. The upper shredding cutter and the lower shredding cutter are arranged in cooperation, and are driven to rotate by means of a driving motor 310 etc. for shredding. The first channel 121 of the first shredding member 120 is connected to the feed port of the mixing bin 410 through a channel. The second shredding member 220 is provided with two outlets, namely a second channel 221 and a third channel 222. The second channel 221 is connected to the mixing bin 410, and the third channel 222 is connected to the temporary storage bin 420. The volume of the mixing bin 410 is not less than the volume of the temporary storage bin 420, and a stirring device is arranged in the mixing bin 410. Both ends of the stirring device are rotatably connected to the upper and lower side walls (the two side walls in the vertical direction) of the mixing bin 410. The drive of the stirring device is arranged at the top or bottom of the mixing bin 410. The discharge port of the mixing bin 410 is arranged on one side of the vehicle body 10. The temporary storage bin 420 is arranged side by side with the mixing bin 410, and the discharge port of the temporary storage bin 420 is arranged on the other side of the vehicle body 10 (the side wall opposite to the discharge port of the mixing bin 410). The configuration actuator can move up and down in the vertical direction.

[0036] A material distribution gate 300 is arranged in the second channel 221 and the third channel 222. The material distribution gate 300 adopts, but is not limited to, a switch such as a motor-driven cover plate or a rotating shaft-driven flap that can switch and cover the second channel 221 or the third channel 222. The material distribution gate 300 is electrically connected to the biomass evaluation module, and the material distribution gate 300 is controlled to switch through the command output module. Among them, the first cutting member 110 corresponds to the first crop with a relatively large weight portion ratio, and the second cutting member 210 corresponds to the first crop with a relatively low weight portion ratio. For example, if the weight portion ratio of corn straw to sorghum-sudangrass is 2:1, then the first cutting member 110 is used to harvest corn straw, and the second cutting member 210 is used to harvest sorghum-sudangrass.

[0037] Further, when corn and sorghum sudanense are intercropped and harvested, the vehicle body 10 enters the field. The width of the first cutting member 110 is the same as the planting width of corn, and the width of the second cutting member 210 is the same as the planting width of sorghum sudanense. The operator operates the vehicle body 10 to move along a preset direction. The biomass evaluation module obtains the biomass characteristic information of the first crop and the second crop. The operator inputs a preset ratio. At the same time, according to the preset ratio, the calculation and comparison of the biomass of the first crop and the second crop are carried out. As the vehicle body 10 moves, the first cutting member 110 and the second cutting member 210 respectively harvest corn straws and sorghum sudanense. The corn straws enter the first crushing member 120 to be crushed and fall into the mixing bin 410 from the first channel 121. The second cutting member 210 is located behind the first cutting member 110, harvests the sorghum sudanense and transports it into the second crushing member 220 for crushing. The crushed sorghum sudanense enters the mixing bin 410 from the second channel 221 (the distribution gate 300 initially covers the third channel 222, so that the second channel 221 is communicated with the mixing bin 410, and the third channel 222 is closed with the temporary storage bin 420, that is, the distribution gate 300 is in the first position). When the biomass evaluation module feeds back that the weight portion of the sorghum sudanense cut by the second cutting member 210 and crushed by the second crushing member 220 reaches the preset standard, the command output module controls the control actuator of the distribution gate 300 to close the second channel 221, so that the third channel 222 is communicated with the temporary storage bin 420, that is, the distribution gate 300 is in the first position. The excess crushed sorghum sudanense enters the temporary storage bin 420 from the third channel 222. At the same time, the stirring device in the mixing bin 410 rotates continuously to stir the crushed sorghum sudanense and corn straws in the mixing bin 410 evenly and store them. When the biomass evaluation module feeds back that the weight ratio of the corn straws cut by the first cutting member 110 and crushed by the first crushing member 120 matches the weight ratio of the sorghum sudanense (as described above, the weight ratio of corn straws to sorghum sudanense is 2:1), the biomass evaluation module controls the distribution gate 300 to change from closing the second channel 221 to closing the third channel 222 (switching from the second position to the first position), so that the sorghum sudanense continues to be crushed and enters the mixing bin 410, and the above steps are repeated until the harvesting is completed or the mixing bin 410 and the temporary storage bin 420 are full and then stop.

[0038] The technical solution of the present application adopting a harvester for the intercropping mode of corn and sorghum sudanense can achieve the following beneficial effects: 1. By setting the biomass evaluation module to control the biomass of corn straws and sorghum sudanense, the problem of mixed harvesting and inability to adjust the weight ratio of the first crop and the second crop is solved. At the same time, the problem of high labor intensity and low working efficiency in adjusting the weight ratio after separate harvesting and crushing is solved.

[0039] 2. By setting several groups of cutting and crushing components and adjusting the harvesting range, the problems of low harvesting efficiency and high cost consumption when using medium and small-sized machinery for harvesting after large-scale planting are solved.

[0040] Based on the above solution, the horizontal projection of the second crop harvesting component 200 is located on the side of the horizontal projection of the first crop harvesting component 100 away from the traveling direction. The first crop harvesting component 100 and the second crop harvesting component 200 are arranged in a stepped manner, and the horizontal projection of the end of the first cutting member 110 away from the vehicle body 10 is in front of the horizontal projection of the end of the second cutting member 210 away from the vehicle body 10 (the front is the direction in which the vehicle body 10 moves along the predetermined direction). The first cutting member 110 and the second cutting member 210 are both connected to the vehicle frame. The first cutting member 110 and the second cutting member 210 are arranged on the vehicle body 10 in a stepped manner, and the first cutting member 110 and the second cutting member 210 cut different crops respectively, solving the problem that when the first crop and the second crop are harvested, the first crop enters the second cutting member 210 or the second crop enters the first cutting member 110, resulting in a deviation in the proportion of silage.

[0041] Based on the above solution, for more convenient operation, the biomass acquisition component includes a density collector and a height collector. The density collector is used to obtain the first density information of the first crop and the second density information of the second crop respectively. The height collector is used to obtain the first height information of the first crop and the second height information of the second crop respectively. The biomass evaluation module includes a ratio input module, a mass conversion module, and a ratio judgment module. The ratio input module is used to respond to the operator's operation and input the standard biomass ratio of the first crop and the second crop. The mass conversion module is electrically connected to the density collector and the height collector respectively, and is used to receive the first density information, the second density information, the first height information, and the second height information, and obtain the first actual biomass of the first crop and the second actual biomass of the second crop according to the mass formula. The ratio judgment module calculates the second standard biomass based on the standard ratio and the first actual biomass, and judges whether the second actual biomass is the same as the second standard biomass. If they are the same, the instruction output module issues an instruction to close the second channel 221 of the material distribution gate 300. The density collector is any one or more of a light transmittance detector, a crop scanner, a laser scanner, a spectral analyzer, and a camera image recognizer.

[0042] Specifically, the biomass acquisition component uses but is not limited to crop scanners, laser scanners, spectral analysis, camera image recognition, etc., and is specifically selected according to surrounding environmental factors. For example, if the light transmittance detector is affected by weather and crop humidity, resulting in a larger error, then spectral analysis or camera image recognition is selected. Preferably, multiple ones are set at the same position, and data is acquired multiple times to improve the accuracy of the acquired data. And at least two are set, which are respectively set on both sides of the vehicle body 10 or at the junction of the first cutting member 110 and the second cutting member 210; the density collector and the height collector are also set at least two, which are respectively set on both sides of the vehicle body 10 or at the junction of the first cutting member 110 and the second cutting member 210. The density collector uses a transmittance detector to obtain the density of corn straw and sorghum sudanense through the light transmittance. The density collector is used to collect the first density information of the first crop and the second density information of the second crop, and the height collector is used to collect the first height information and the second height information of the first crop and the second crop.

[0043] The ratio input module further includes a display and ratio adjustment buttons. The operator adjusts the biomass ratio of the first crop and the second crop by pressing the adjustment buttons. This ratio can be appropriately adjusted through the feedback after subsequent harvesting and feeding, and the ratio input module gives a more optimal ratio for the operator to select, and the operator can adjust the ratio by himself. The mass conversion module uses a computer, a processor, etc., and there is a mass formula stored in the mass conversion module, where the mass formula is: Among them, is the first or second actual biomass, is the first or second density information, is the height of the first or second crop, is the standard mass of the first or second crop per unit height, and n is 1, 2, 3...

[0044] Among them, is the average weight, is the average height, N is the number of experimental groups, and i is 1, 2, 3... n.

[0045] S n In S, n = 1, 2, 3..., the density collector continuously obtains its first density information and second density information, and continuously reviews them. The density collector collects the density of the first crop and the second crop per unit area each time. The unit area can be set by the operator to be 1㎡, 5㎡, 10㎡, etc. n In E, n = 1, 2, 3..., taking the first height information as an example, the first height information is the height of the corn straw. There are several pieces of first height information collected by the height collector, among whichn is the average height of corn straw per unit area collected by the density collector. By multiplying the average height by the density and then multiplying by the standard mass of the crop per unit height, the weight of the corn straw per unit area can be obtained; the standard mass of the crop per unit height is entered through the Internet and experiments. Among them, for the artificial experiment, the standard mass of the crop per unit height is determined through a large number of experiments. For example, for the first crop, which is corn straw, several corn straws are selected, and the height h 1 、h 2 、h 3 、h 4 、……h n is measured and recorded. Then, the sum is calculated and the average height H 1 is obtained. H 1 = (h 1 + h 2 + h 3 + …… + h n ) / n. And the average weight is calculated by weighing the weight corresponding to its height. For example, the weights m n are weighed, where n = 1, 2, 3... (m 1 、m 2 、m 3 、m 4 、……m n correspond to h 1 、h 2 、h 3 、h 4 、……h n ), and the average weight M 1 is calculated. M 1 = (m 1 + m 2 + m 3 + …… + m n ) / n. Repeat the above steps for multiple groups of experiments, and calculate the average weights M 2 、M 3 、M 4 、……M n and the average heights H 2 、H 3 、H 4 、……H n . Sum all the average weights M, divide by the sum of all the average heights H, and divide by the number N to obtain the standard mass of the crop per unit height of the corn straw. Similarly, for the second crop, which is sorghum-sudan grass, repeat the above experiment to obtain the standard mass of the crop per unit height of the sorghum-sudan grass.

[0046] Input Then, the first height information or the second height information and the first density or the second density are obtained to calculate the first actual biomass and the second actual biomass; the proportion information is obtained, and the first standard biomass is calculated by the second standard biomass of the second crop (such as sorghum) with a smaller preset proportion.

[0047] In the preferred implementation scheme of the present application, the material distribution gate 300 includes a baffle 320 and a motor 310, the second channel 221 and the third channel 222 are arranged in an eight-shape, the motor 310 is arranged at the connection between the second channel 221 and the third channel 222, and the motor 310 is connected to one end of the baffle 320, for driving the baffle 320 to switch back and forth between the first position and the second position; the size of the baffle 320 is not less than the cross-sectional size of the second channel 221 and the third channel 222.

[0048] The first position is that the baffle 320 covers the third channel 222, and the second position is that the baffle 320 covers the second channel 221. The baffle 320 can be switched back and forth between the first position and the second position driven by the motor 310 (i.e., the control actuator). The cross-sectional dimensions of the second channel 221 and the third channel 222 are the same. Similarly, the dimensions of the baffle 320 and the cross-sectional dimensions of the second channel 221 are also the same. By controlling the forward and reverse rotation and start and stop of the motor 310, the switching of the baffle 320 between the first position and the second position is achieved. The operation is simple and convenient, and the problem of controlling the biomass ratio of the second crop is solved.

[0049] Furthermore, the material dividing gate 300 also includes a first limit block 330 and a second limit block 340. The first limit block 330 and the second limit block 340 are symmetrically arranged and are respectively located on the inner wall of the second channel 221 and the third channel 222 away from the motor 310, for limiting the position of the baffle 320.

[0050] The first limit block 330 is set at the second position of the baffle 320, and the second limit block 340 is set at the first position of the baffle 320. When the baffle 320 contacts the first limit block 330, the problem that the baffle 320 flips too much, resulting in the baffle 320 being unable to cover the third channel 222, and the second crop enters the temporary storage bin 420 from the gap between the third channel 222 and the baffle 320 is solved. On the contrary, when the second limit block 340 contacts the baffle 320, the problem that the baffle 320 cannot completely close the second channel 221 is solved, and the bearing capacity of the baffle 320 is improved.

[0051] In another embodiment of the present application, in order to improve the accuracy of the harvested weight, the material distribution gate 300 further includes a flow detector and a timer. The flow detector and the timer are both arranged on the side walls of the second channel 221 and the first channel 121. The flow detector is used to detect the flow rate of the material per unit time, and the timer is used for timing. The flow detector and the timer are both electrically connected to the mass conversion module. The mass conversion module calculates the first actual biomass through the flow rate per unit time and the time, and averages it with the first actual biomass calculated by the mass conversion module through the mass formula, and then sends it to the ratio judgment module for judgment. Similarly, the second actual biomass is also obtained by averaging twice.

[0052] Further, the mass conversion module is provided with a review formula, and the review formula is (n + 3) × V 平均 , where n is the unit time, and V 平均 is the average material flow rate in n unit times. The mass conversion module calculates the first actual biomass and the second actual biomass through the review formula, and the review formula is used to estimate the first actual biomass and the second actual biomass after 3 unit times. After the ratio judgment module determines that the first actual biomass is equal to the first standard biomass, it issues an instruction to turn on the motor 310 after 3 unit times and flip the baffle 320, and at the same time issues an instruction to zero the flow detector and the timer located in the second channel 221 and re-detect and time. Similarly, after the ratio judgment module determines that the second actual biomass is equal to the second standard biomass, it issues an instruction to turn on the motor 310 after 3 unit times and flip the baffle 320, and at the same time issues an instruction to zero the flow detector and the timer located in the second channel 221 and re-detect and time.

[0053] A volume sensor and a warning device are arranged in the mixing bin 410 and the temporary storage bin 420. The volume sensor is used to detect the material volume in the mixing bin 410 and the temporary storage bin 420. The warning device is electrically connected to the volume sensor. When the material volume in any one of the mixing bin 410 or the temporary storage bin 420 reaches the threshold of the volume sensor, the warning device starts to give a warning. By setting the volume sensor and the warning device, the problem that it is difficult for the operator to predict after the mixing bin 410 and the temporary storage bin 420 are full is solved.

[0054] Please refer to Figure 10 , a working method of a harvester for the intercropping mode of corn and sorghum sudanense, which is applied to the harvester for the intercropping mode of corn and sorghum sudanense as described above, and includes the following steps: Step S10: Respond to the operation of the operator, set the standard ratio by the operator, and then the ratio input module outputs the standard ratio to the mass conversion module.

[0055] Step S20: Obtain the biomass characteristic information of the first crop and the second crop, and based on the standard ratio, output the first standard biomass characteristic information and the second standard biomass characteristic information; the biomass characteristic information of the first crop (including the first density information and the first height information) and the biomass characteristic information of the second crop (including the second density information and the second height information), calculate the first standard biomass and the second standard biomass through the standard ratio, and send them to the ratio judgment module.

[0056] Step S30: Obtain the first actual biomass and determine whether the first actual biomass is equal to the first standard biomass; substitute the first density information, the first height information, the second density information, and the second height information into the mass formula to calculate the first actual biomass, and compare the first actual biomass with the first standard biomass.

[0057] If so, output the instruction to close the second channel 221 by the material distribution gate 300; if the same, start the motor 310, flip the baffle 320 closed on the third channel 222 from the first position to the second position, and close the second channel 221; if not, continue to obtain and compare.

[0058] Step S40: Obtain the second actual biomass and determine whether the second actual biomass is equal to the second standard biomass; after the first actual biomass is the same as the first standard biomass, obtain the second actual biomass according to the second density information and the second height information, and compare the second actual biomass with the second standard biomass.

[0059] If so, output the instruction to close the third channel 222 by the material distribution gate 300; if the same, start the motor 310 and rotate in the reverse direction, flip the baffle 320 closed on the second channel 221 from the second position to the first position, and close the third channel 222; if not, continue to obtain and compare.

[0060] Step S50: Repeat the above steps S30 to S40; when the baffle 320 is flipped from the first position to the second position for the first time, the second actual biomass is reset and the above steps are repeated again.

[0061] Based on the above solution, in step S30, when obtaining the first actual biomass and the second actual biomass, the following steps are further included: Step S31: Obtain the first density information, the first height information, and the standard mass, and output the first actual biomass; Step S32: Obtain the second density information, the second height information, and the standard mass, and output the second actual biomass.

[0062] The standard quality is set by the operator, and its range is restricted through experiments, the Internet, etc., and is calculated through a quality formula, so as to calculate the first actual biomass characteristic information and the second actual biomass characteristic information.

[0063] The specific steps are as follows: After the vehicle body 10 enters the field, the first cutting member 110 corresponds to the first crop, and the second cutting member 210 corresponds to the second crop. The operator inputs the standard ratio and then feeds it back to the quality conversion module. The operator operates the vehicle body 10 to move along the preset direction, and at the same time obtains the biomass characteristic information of the first crop (including the first density information and the first height information) and the biomass characteristic information of the second crop (including the second density information and the second height information), and feeds them back to the quality conversion module. The vehicle body 10 moves forward, the first cutting member 110 cuts the first crop, and then enters the first crushing member 120 to be crushed. The crushed first crop enters the mixing bin 410 from the first channel 121. Immediately afterwards, the second cutting member 210 located behind the first cutting member 110 cuts the second crop, and the cut second crop enters the second crushing member 220 for crushing. The crushed second crop first enters the mixing bin 410 from the second channel 221, and in the mixing bin 410, the stirring device stirs it evenly with the crushed first crop.

[0064] When the ratio judgment module compares that the actual biomass of the first crop is the same as the standard biomass of the first crop, the ratio judgment module issues an instruction to close the second channel 221 of the material distribution gate 300, thereby starting the motor 310, which drives the baffle 320 to flip from the first position to the second position, opening the third channel 222 and closing the second channel 221, so that the crushed second crop enters the temporary storage bin 420 from the third channel 222. The vehicle continues to move. When it is judged that the actual biomass of the second crop is the same as the standard biomass of the second crop, the ratio judgment module issues an instruction to close the third channel 222 of the material distribution gate 300, thereby starting the motor 310 again, which rotates in the reverse direction to drive the baffle 320 to flip from the second position to the first position, opening the second channel 221 and closing the third channel 222, so that the crushed second crop continues to enter the mixing bin 410 from the second channel 221. The harvesting of the vehicle body 10 stops until any one of the mixing bin 410 or the temporary storage bin 420 is full or the harvesting is completed.

[0065] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
