[0044] The following will describe in detail the specific implementation of the present invention in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention and is not used to limit the present invention.

[0045] The cleaning monitoring device 100 according to the present invention will be described below with reference to the accompanying drawings. As Figure 1 shown, it is a schematic diagram of the application scenario of the cleaning monitoring device 100 provided according to an embodiment of the present invention. As Figure 2 shown, it is a schematic diagram of the structure of the cleaning monitoring device 100 provided according to an embodiment of the present invention. In the embodiment of the present invention, the cleaning monitoring device 100 is arranged in a cleaning chamber, and a cleaning sieve 22 is arranged in the cleaning chamber. The monitoring device 100 includes:

[0046] The guiding member 1 is located above the cleaning sieve 22, and the guiding member 1 is fixed to both ends of the cleaning sieve 22 along the length direction in the first direction;

[0047] The sensor mounting mechanism 2 is mounted on the guiding member 1 and can move on the guiding member 1. The sensor mounting mechanism 2 extends in the second direction;

[0048] The sensors 3 are at least one in number and are mounted on the sensor mounting mechanism 2. The position of the sensors 3 on the sensor mounting mechanism 2 is adjustable in the second direction, and the first direction and the second direction intersect.

[0049] The cleaning chamber is located inside the cleaning device. The cleaning device is a device for grading and removing impurities from crops. The agricultural harvester cleans the crops by controlling the wind speed of the airflow field in the cleaning chamber. A cleaning fan 21 for providing wind power towards the cleaning sieve 22 is further provided in the cleaning device to provide cleaning power for the crops. For an agricultural harvester, the threshing cylinder 23 is located above the cleaning sieve 22, threshes the crops, and then transports the threshed crops to the cleaning chamber for threshing. The distribution of the airflow field above the cleaning sieve 22 has the most significant influence on the cleaning efficiency and the cleaning result. Therefore, the embodiment of the present invention provides a monitoring device 100 for the cleaning airflow field, which can monitor the wind speed above the cleaning sieve 22.

[0050] Specifically, in the embodiment of the present invention, the cleaning device includes a guiding member 1. The guiding member 1 is located above the cleaning sieve 22 and is fixed to both sides of the cleaning sieve 22 along the length direction in the first direction. The sensor mounting mechanism 2 can move along the extending direction of the guiding member 1. The sensor mounting mechanism 2 is mounted with sensors 3, and the movement of the sensor mounting mechanism 2 will drive the sensors 3 to move. The number of the sensors 3 is one or more, and the multiple sensors 3 can be arranged in sequence in the second direction on the sensor mounting mechanism 2, and the position of the sensors 3 on the sensor mounting mechanism 2 is adjustable in the second direction, so that the monitoring device 100 can monitor multiple positions of the airflow field above the cleaning sieve 22. The first direction and the second direction intersect, and the specific directions can refer to Figure 2 the direction marks in. In a specific embodiment, both the first direction and the second direction are parallel to the horizontal plane.

[0051] By using the cleaning monitoring device 100 provided by the embodiment of the present invention, since the position of the sensors 3 is adjustable in both the second direction and the first direction, the monitoring range can be expanded, the monitoring efficiency can be higher, and the monitoring effect can be better, so as to meet the monitoring requirements for the wind speed of the airflow field above the cleaning sieve 22 in the cleaning chamber.

[0052] In one embodiment, the cleaning monitoring device 100 is detachably connected to the cleaning sieve 22, and the monitoring device 100 can be removed after the monitoring is completed, so as to reduce the influence on the airflow field in the cleaning chamber.

[0053] In one embodiment, the sensor mounting mechanism 2 includes: side section mounting brackets 201, two in number; a middle section mounting bracket 202, which is located between the two side section mounting brackets 201. The two ends of the middle section mounting bracket 202 are movably sleeved inside the side section mounting brackets 201, and the overlapping length between the middle section mounting bracket 202 and the side section mounting brackets 201 is adjustable; the sensor mounting mechanism 2 further includes: a first locking member 203 for locking the overlapping portion between the middle section mounting bracket 202 and the side section mounting brackets 201. Since the lengths of the cleaning sieves 22 of different types and models of agricultural harvesters are different, if a monitoring device 100 is designed separately for each device, the cost will be relatively high. The sensor mounting mechanism 2 of the present invention includes side section mounting brackets 201 and a middle section mounting bracket 202. The middle section mounting bracket 202 is movably sleeved inside the side section mounting brackets 201. The user can adjust the position between the middle section mounting bracket 202 and the side section mounting brackets 201 to adjust the length of the sensor mounting mechanism 2 to adapt to cleaning sieves 22 of different lengths. The first locking member 203 can lock the overlapping position between the middle section mounting bracket 202 and the side section mounting brackets 201 to prevent the side section mounting brackets 201 and the middle section mounting bracket 202 from separating from each other. For example, the monitoring device 100 of the present invention can be applicable to different models of rice combine harvesters, wheat combine harvesters, etc.

[0054] In one embodiment, the side section mounting brackets 201 and the middle section mounting bracket 202 are both provided with long strip through holes 206 along the second direction. When the side section mounting brackets 201 and the middle section mounting bracket 202 overlap, the two long strip through holes 206 overlap with each other. The first locking member 203 passes through the two long strip through holes 206 to lock the overlapping portion between the side section mounting brackets 201 and the middle section mounting bracket 202.

[0055] In a specific embodiment, when the first locking member 203 locks the overlapping portion between the side section mounting brackets 201 and the middle section mounting bracket 202, the first locking member 203 can move along the long strip through hole 206 to facilitate the relative movement between the side section mounting brackets 201 and the middle section mounting bracket 202.

[0056] In a specific embodiment, the side section mounting brackets 201 and the middle section mounting bracket 202 are both provided with long strip through holes 206 along the second direction. The positions of the long strip through holes 206 are provided with corrugated limiting portions (not shown in the figure) along the length direction. When the first locking member 203 passes through the two long strip through holes 206, the first locking member 203 cannot move in the long strip through hole 206 under the action of the corrugated limiting portion, and the first locking member 203 locks the side section mounting brackets 201 and the middle section mounting bracket 202.

[0057] In one embodiment, the guide member 1 can be a straight line, or can be in any form such as a curve or an arc. The guide member 1 can include a set of two, and the two guide members 1 can be completely identical, or can also be different. When the sensor mounting mechanism 2 moves on the guide member, the two mounting ends can move synchronously, or can also move asynchronously. The asynchronous movement of the two ends can be achieved by adjusting the length of the sensor mounting mechanism. For example, by adjusting the length of the sensor mounting mechanism 2, only the mounting end on one guide member 1 is moved to achieve the roll of the sensor mounting mechanism 2. (The method of adjusting the length of the sensor mounting mechanism 2 is achieved by the adjustment and locking of the above-mentioned side section mounting frame 201 and middle section mounting frame 202)

[0058] When the guide member 1 is a straight line, the guide member 1 can be the side strip plate of the cleaning chamber, or can also be a separately provided guide member 1. When the guide member 1 of the present application is a straight line, the structural form of the guide member 1 can be the following two types:

[0059] In the first embodiment, the guide member 1 is a guide rail, and a slider (not shown in the figure) is slidably connected to the guide rail. The slider is connected to the sensor mounting mechanism 2. The user can drive the slider to move along the extension direction of the guide rail, so that the sensor 3 can move along the extension direction of the guide rail to monitor the wind speed at different positions in the first direction. Further, a fifth locking member (not shown in the figure) is also mounted on the slider, and the fifth locking member is used to lock the slider to the guide rail.

[0060] In the second embodiment, the guide member 1 is a rotating lead screw, and a rotating nut (not shown in the figure) is helically sleeved on the rotating lead screw. The rotating nut is connected to the sensor mounting mechanism 2. The monitoring device 100 further includes: a rotating driving member 5, which is drivingly connected to the rotating lead screw. The rotating driving member 5 can drive the rotating lead screw to rotate. The rotation of the rotating lead screw can drive the rotating nut to move linearly in the extension direction of the rotating lead screw, so that the sensor 3 on the sensor mounting mechanism 2 can monitor the wind speed at different positions in the first direction.

[0061] In one embodiment, as Figure 3 shown, it is Figure 2Partial enlarged schematic diagram of part A. The sensor mounting mechanism 2 further includes: a mounting seat assembly 204, slidably connected to the guide member 1 and detachably connected to the end of the side segment mounting frame 201; and a second locking member 205 for locking the side segment mounting frame 201 and the mounting seat assembly 204 and adjusting the relative angle therebetween. The end of the side segment mounting frame 201 can rotate relative to the mounting seat assembly 204, and the second locking member 205 can lock the side segment mounting frame 201 and the mounting seat assembly 204. After the second locking member 205 locks the side segment mounting frame 201 and the mounting seat assembly 204, the end of the side segment mounting frame 201 cannot rotate relative to the mounting seat assembly 204. With the above structure, the angle of the sensor 3 can be changed so that the sensor 3 can monitor the wind speed of the airflow field at different angles, making the monitoring data more comprehensive and the monitoring effect better.

[0062] In one embodiment, as Figure 3 shown, the mounting seat assembly 204 further includes: a connecting plate 2041, provided with a circular mounting hole (not shown in the figure) and an arc-shaped mounting hole 20411. One second locking member 205 is inserted into the arc-shaped mounting hole 20411 and passes through the side segment mounting frame 201, and the other second locking member 205 is inserted into the circular mounting hole and passes through the side segment mounting frame 201. The number of the second locking members 205 is two, and the two second locking members 205 can better lock the side segment mounting frame 201 and the connecting plate 2041. Two threaded holes (not shown in the figure) are provided on the side of the side segment mounting frame 201 close to the connecting plate 2041. The user can insert one second locking member 205 into the circular mounting hole and one threaded hole of the side segment mounting frame 201 to mount the side segment mounting frame 201 on the connecting plate 2041. The user can insert the other second locking member 205 into the arc-shaped mounting hole 20411 and the other threaded hole of the side segment mounting frame 201 to fix the side segment mounting frame 201 and the connecting plate 2041. The user can unlock the locking member inserted into the arc-shaped mounting hole 20411 to rotate the side segment mounting frame 201 relative to the connecting plate 2041 to adjust the angle of the sensor 3.

[0063] In one embodiment, as Figure 3As shown, the mounting seat assembly 204 further includes: a mounting plate 2042, which is attached to the side of the connecting plate 2041 facing away from the side section mounting bracket 201. Both the mounting plate 2042 and the connecting plate 2041 are provided with adjustment holes 2044 extending in the height direction, and the height direction intersects both the first direction and the second direction; and a third locking member 2043, which sequentially passes through the two adjustment holes 2044 to lock the mounting plate 2042 and the connecting plate 2041. The length of the adjustment hole 2044 is relatively long, and the third locking member 2043 can lock the mounting plate 2042 and the connecting plate 2041 at different relative heights. The height of the mounting plate 2042 is fixed relative to the cleaning sieve 22. When changing the relative height of the mounting plate 2042 and the connecting plate 2041, the height of the connecting plate 2041 can be changed. The connecting plate 2041 is connected to the side section mounting bracket 201, and the sensor 3 is installed on the side section mounting bracket 201 and / or the middle section mounting bracket 202. Therefore, changing the height of the connecting plate 2041 changes the height of the sensor 3, enabling the sensor 3 to monitor the wind speed at different heights relative to the cleaning sieve.

[0064] In a specific embodiment, as Figure 3 shown, the circular mounting hole of the connecting plate 2041 is located above the arc-shaped mounting hole 20411, and the side section mounting bracket 201 can be rotated by adjusting the position of the second locking member 205 in the arc-shaped mounting hole 20411. The adjustment holes 2044 of the connecting plate 2041 are located on both sides of the arc-shaped mounting hole 20411. The relative positions of the mounting plate 2042 are also provided with adjustment holes 2044, and a relief groove 20421 for the second locking member 205 is provided between the two adjustment holes 2044 of the mounting plate 2042 to facilitate the installation and removal of the second locking member 205.

[0065] In an embodiment, as Figure 2 shown, the monitoring device 100 further includes: fourth locking members 4, the number of which is the same as the number of sensors 3, and the fourth locking members 4 lock the sensors 3 to the sensor mounting mechanism 2 one by one.

[0066] In a specific embodiment, as Figure 2 shown, the fourth locking members 4 lock the sensors 3 to the side section mounting bracket 201 and the middle section mounting bracket 202.

[0067] In an embodiment, as Figure 4 shown, it is a schematic structural diagram of another perspective of the cleaning monitoring device 100 according to an embodiment of the present invention. As Figure 5 shown, for Figure 4Partial enlarged schematic view of part B. A sensor installation groove 207 extending in the second direction is formed on the sensor installation mechanism 2. The fourth locking member 4 is inserted into the sensor installation groove 207 and locks the sensor 3 and the sensor installation mechanism 2. The length of the sensor installation groove 207 is relatively long. The fourth locking member 4 is inserted into the sensor installation groove 207, and the sensor 3 can be locked at different positions in the sensor installation groove 207 to finely adjust the position of the sensor 3 in the second direction.

[0068] By using the above-mentioned cleaning monitoring device 100, the sensor 3 can be adjusted in the first direction, the second direction and the height direction, and the angle of the sensor 3 can also be changed. Compared with the traditional monitoring structure, the present invention can monitor more positions, and can more conveniently change the monitoring position of the sensor 3 to meet the monitoring requirements of the wind speed at different positions in the airflow field. In addition, the length of the sensor installation mechanism 2 in the monitoring device 100 provided by the present invention can be adjusted, so that its application scenarios are more extensive and it can be adapted to different types and models of agricultural harvesters.

[0069] In one embodiment, a cleaning monitoring method is provided, which is applied to the above-mentioned cleaning monitoring device 100. The cleaning monitoring device 100 is arranged in the cleaning chamber of the cleaning device. As Figure 6 shown, it is a flowchart of the cleaning monitoring method provided by the embodiment of the present invention. The monitoring method includes:

[0070] S101, start the cleaning device to perform cleaning operations;

[0071] S102, obtain the first wind speed signal monitored by the sensor 3 at the first position;

[0072] S103, determine the wind speed at the first position according to the first wind speed signal;

[0073] S104, adjust the position of the sensor 3 so that the sensor 3 moves to the second position;

[0074] S105, obtain the second wind speed signal monitored by the sensor 3 at the second position;

[0075] S106, determine the second wind speed at the second position according to the second wind speed signal.

[0076] When it is necessary to monitor the wind speed in the cleaning chamber, the user can set the cleaning monitoring device 100 in the cleaning chamber of the cleaning device and start the cleaning device to perform a cleaning operation. The processor of the cleaning device obtains a first wind speed signal monitored by a group of sensors 3 and can determine the wind speed at the first position according to the first wind speed signal. Subsequently, the position of the sensor 3 can be adjusted so that the position of the sensor 3 is adjusted from the first position to the second position. Obtain a second wind speed signal monitored by the sensor 3 at the second position and determine the wind speed at the second position according to the second wind speed signal. Similarly, the position of the sensor 3 can be changed multiple times so that the cleaning monitoring device 100 can monitor the wind speed at multiple positions in the cleaning chamber.

[0077] In one embodiment, adjusting the position of the sensor 3 so that the sensor 3 moves to the second position includes: controlling the sensor mounting mechanism 2 to move in the first direction and / or adjusting the position of the sensor 3 in the second direction. The user can change the position of the sensor 3 by controlling the sensor mounting mechanism 2 to move in the first direction, or directly adjust the position of the sensor 3 on the sensor mounting mechanism 2 to change the position of the sensor 3 in the second direction, where the first direction and the second direction refer to the Figure 2 identifications in. By using the above monitoring method, the wind speed at multiple positions in the same horizontal plane in the cleaning chamber can be monitored, making the monitoring more convenient and faster.

[0078] In one embodiment, as Figure 1 and Figure 2 shown, adjusting the position of the sensor 3 further includes: adjusting the height of the sensor 3 and / or adjusting the angle of the sensor 3. The user can adjust the height of the sensor 3 and / or adjust the angle of the sensor 3 to change the position of the sensor 3. The angle of the sensor 3 can be the angle of the sensor 3 relative to the cleaning sieve plane. The housing of the sensor 3 can be a rod-shaped structure, and the angle between the rod-shaped structure and the cleaning sieve plane is the angle of the sensor 3. The height of the sensor 3 can be the relative height of the sensor 3 relative to the cleaning sieve plane, and the height difference between the center point of the sensor 3 and the cleaning sieve is the height of the sensor 3. Specifically, the user can adjust the locking position of the second locking member 205 to adjust the angle of the sensor 3, or adjust the locking position of the third locking member 2043 to adjust the height of the sensor 3. By using the above monitoring method, the wind speed at multiple heights can be monitored, and the angle of the sensor 3 can be adjusted so that the user can obtain more comprehensive wind speed information in the cleaning chamber.

[0079] In a specific embodiment, the sensor mounting mechanism 2 continuously moves in the first direction multiple times to obtain multiple groups of wind speed signals to determine the distribution of the wind speed in the first direction.

[0080] In a specific embodiment, the user adjusts the position of the sensor 3 in the second direction multiple times to obtain multiple sets of wind speed signals, so as to determine the distribution of the wind speed in the second direction.

[0081] In one embodiment, an agricultural harvester is provided, including: a cleaning device with a cleaning chamber inside; and the above-mentioned cleaning monitoring device 100.
