Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a transport device for harvesting tobacco leaves and a harvesting method. Background Art

[0002] With the advancement of science and technology, the degree of agricultural mechanization is getting higher and higher. For example, tobacco leaf carrying equipment is used in the process of tobacco leaf harvesting. The carrying equipment includes a frame and a running mechanism at the bottom of the frame. When collecting tobacco leaves, the running mechanism drives the frame to walk in the ridges of the tobacco field, and the harvesters harvest the tobacco leaves on both sides of the ridges and place them on the frame. Since the side walls of the ridges of the tobacco field are generally sloped and the bottom of the ridges is very narrow, the running mechanism needs to be set to be narrower accordingly, for example, only one row of running wheels distributed along the front and rear directions of the frame is set to be able to walk in the ridges. However, the narrow running mechanism will cause the frame support to be unstable and it is easy to roll over. In addition, in order to avoid the carrying equipment being far away from the harvesters, after the carrying equipment moves to the vicinity of the harvesters, the harvesters need to turn off the running mechanism and start the running mechanism when going to the next location for picking. The operation is troublesome, time-consuming and labor-intensive, and inconvenient to use. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a tobacco leaf harvesting carrying device, which is not only convenient for walking in the narrow furrow at the bottom, but also does not roll over and has better stability. In addition, the carrying device can move to the vicinity of the harvester by itself, making it more convenient to use.

[0004] The present invention also provides a harvesting method with the above-mentioned tobacco leaf harvesting transporting equipment.

[0005] According to the first aspect of the present invention, a transport device for harvesting tobacco leaves comprises a frame, a walking mechanism and two groups of guide rollers, wherein the frame is used for placing tobacco leaves, the frame is provided with a first distance measuring sensor, the first distance measuring sensor is used for detecting the distance between the frame and a harvester in the front-rear direction of the frame, the walking mechanism is provided on the frame to drive the frame to walk in a furrow, the two groups of guide rollers are respectively provided on both sides of the frame in the left-right direction, the outer side walls of the guide rollers are used to fit the side walls of the furrow, the guide rollers can rotate around their own axis, and the axis of the guide rollers is perpendicular to the front-rear direction of the frame; wherein, when the harvester is located in front of the frame and the distance value detected by the first distance measuring sensor is greater than a first preset value, the walking mechanism starts; when the harvester is located behind the frame and the distance value detected by the first distance measuring sensor is greater than a second preset value, the walking mechanism stops running.

[0042] Reference below Figures 1 to 6 The tobacco leaf harvesting carrying equipment and the tobacco leaf harvesting method according to the embodiments of the present invention are described.

[0043] refer to Figures 1 to 6 As shown, the tobacco leaf harvesting carrying equipment according to the first embodiment of the present invention includes a frame 100, a walking mechanism 200 and two sets of guide rollers 300.

[0044] Among them, a placement groove may be formed at the top of the frame 100, and the placement groove is used to place tobacco leaves. A storage cavity may also be provided in the frame 100, and a controller and a power module may be installed in the storage cavity. The controller may be electrically connected to the traveling mechanism 200, and the controller is used to control the operation of the traveling mechanism 200. The power module provides power for the traveling mechanism 200 and the controller. The frame 100 is provided with a first distance measuring sensor 101, and the first distance measuring sensor 101 may be electrically connected to the controller. The first distance measuring sensor 101 is used to detect the distance between the frame 100 and the harvesting personnel in the front and rear direction of the frame 100. The first distance measuring sensor 101 may be an ultrasonic sensor, an infrared sensor, a radar or other suitable distance measuring sensors. The first distance measuring sensor 101 may be one or more, for example, two and respectively arranged at the front and rear ends of the frame 100. When the harvester is located on one side of the ditch in front of the frame 100 or on one side of the ditch behind the frame 100 and close to the ditch, the first distance measuring sensor 101 located at the front end of the frame 100 and the first distance measuring sensor 101 located at the rear end of the frame 100 can respectively detect the distance value between the frame 100 and the harvester, which can be equivalent to the distance value in the front and rear direction of the frame 100, or after the controller receives the distance value information sent by the first distance measuring sensor 101, it can calculate the value of the distance between the frame 100 and the harvester in the front and rear direction of the frame 100. The frame 100 can also be provided with a fan 600, which can be an air curtain machine. The fan 600 is provided, and in hot weather, when the harvester is resting, the fan 600 can be used to dissipate heat, reduce the fatigue of the harvester, and facilitate the harvester to rest better.

[0045] The walking mechanism 200 is arranged on the frame 100 to drive the frame 100 to move in the ditch. Since the side walls of the ditch in the tobacco field are generally sloped and the bottom of the ditch is narrow, the walking mechanism 200 needs to be correspondingly set to be narrower. For example, only one row of walking wheels 201 distributed along the front and rear direction of the frame 100, that is, the walking direction of the frame 100, is set to be able to move in the ditch.

[0046] Two groups of guide rollers 300 are respectively arranged on both sides of the left and right directions of the frame 100. Each group of guide rollers 300 may include one or more guide rollers 300. When each group of guide rollers 300 includes multiple guide rollers 300, multiple guide rollers 300 of the same group may be arranged along the front and rear directions of the frame 100. The outer side walls of the guide rollers 300 are used to fit the side walls of the ditch. The guide rollers 300 can rotate around their own axis, and the axis of the guide rollers 300 is perpendicular to the front and rear directions of the frame 100. Specifically, when the frame 100 is moving and the side walls of the ditch are sloped, the axis of the guide rollers 300 may extend along the inclination direction of the side walls of the ditch.

[0047] Among them, when the harvester is located in front of the frame 100, and the distance value detected by the first distance measuring sensor 101 is greater than the first preset value, for example, greater than 5 meters, the first distance measuring sensor 101 sends a signal to the controller, and the controller controls the walking mechanism 200 to start and drive the frame 100 to move forward; when the harvester is located behind the frame 100, and the distance value detected by the first distance measuring sensor 101 is greater than the second preset value, for example, greater than 5 meters, the first distance measuring sensor 101 sends a signal to the controller, and the controller controls the walking mechanism 200 to stop running and stop the frame 100 from moving forward.

[0048] According to the tobacco leaf harvesting transport equipment of the embodiment of the present invention, when collecting tobacco leaves, the walking mechanism 200 drives the frame 100 to walk in the furrows of the tobacco leaf field, and the harvesters harvest the tobacco leaves on both sides of the furrows and place them on the frame 100. The walking mechanism 200 can be set as a row of walking wheels 201 distributed along the front and rear direction of the frame 100 or a crawler track extending along the front and rear direction of the frame 100. In this way, it is convenient to walk in a narrow ditch at the bottom. During the walking process, the outer side walls of the guide rollers 300 on both sides of the frame 100 are attached to the side walls of the ditch. Through the cooperation between the guide rollers 300 and the side walls of the ditch, the frame 100 can be prevented from tipping over, and the stability is better. Moreover, since the guide rollers 300 can rotate around their own axis and the axis of the guide rollers 300 is perpendicular to the front and rear direction of the frame 100, when the frame 100 is walking, the guide rollers 300 will rotate, and the friction force they are subjected to is rolling friction, and the friction resistance is small, thereby making the frame 100 walk more smoothly. In addition, the first distance measuring sensor 101 can detect the distance between the frame 100 and the harvesters in the front and rear directions of the frame 100. When the harvesters are located in front of the frame 100 and the distance value detected by the first distance measuring sensor 101 is greater than a first preset value, the walking mechanism 200 automatically starts and drives the frame 100 to move forward to the vicinity of the harvesters. When the harvesters are located behind the frame 100 and the distance value detected by the first distance measuring sensor 101 is greater than a second preset value, the walking mechanism 200 automatically stops running and stops the frame 100 from moving forward, thereby preventing the frame 100 from being too far away from the harvesters, making it convenient for the harvesters to place the tobacco leaves, and there is no need to manually operate the walking mechanism 200 to start and stop, making it more convenient to use.

[0049] In some embodiments of the present invention, Figure 1As shown, the tobacco leaf harvesting carrying device further includes a telescopic mechanism 400, which is disposed on the frame 100, and the guide roller 300 is connected to the telescopic mechanism 400, and the telescopic mechanism 400 is used to drive the guide roller 300 to move and adjust along the left and right directions of the frame 100. For example, the telescopic mechanism 400 may be an electric push rod, a cylinder, etc., and the telescopic mechanism 400 may extend along the left and right directions of the frame 100 and may be telescopic along the left and right directions of the frame 100, and the guide roller 300 may be disposed at the end of the telescopic mechanism 400.

[0050] The distance between the two side walls of the ditch in different tobacco fields may be different. In this embodiment, by manipulating the telescopic mechanism 400, the corresponding guide roller 300 can be controlled to move and adjust along the left and right directions of the frame 100. Even if the distance between the two side walls of the ditch is different, the outer wall of the guide roller 300 can still be fitted to the side wall of the ditch to prevent the frame 100 from tipping over. In addition, when tobacco leaves are placed on one side of the frame 100, causing the frame 100 to be unevenly stressed and slightly sway to one side, the telescopic mechanism 400 can be adjusted to straighten the frame 100 to achieve smooth walking, which is more practical.

[0051] It should be noted that the telescopic mechanism 400 may be electrically connected to a controller in the vehicle frame 100 , and the telescopic mechanism 400 may be controlled to be telescopic by the controller.

[0052] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, the end of the telescopic mechanism 400 is hinged with a mounting frame 401, both ends of the guide roller 300 are rotatably connected to the mounting frame 401, and the hinge axis between the mounting frame 401 and the telescopic mechanism 400 extends along the front-rear direction of the vehicle frame 100. For example, the mounting frame 401 may include a connecting rod and side rods provided at both ends of the connecting rod, the connecting rod is provided with a connecting seat, the connecting seat is hinged to the end of the telescopic mechanism 400, and both ends of the guide roller 300 are rotatably connected to the two side rods respectively.

[0053] The side walls of the ridges in different tobacco fields may be sloped or not, and the inclination angles may be different when they are sloped. In the present embodiment, the guide roller 300 is hinged to the end of the telescopic mechanism 400 through the mounting frame 401, and the hinge axis between the mounting frame 401 and the telescopic mechanism 400 extends along the front-rear direction of the frame 100. Thus, when the telescopic mechanism 400 is extended to make one end of the guide roller 300 begin to contact the side wall of the ridge, if the telescopic mechanism 400 continues to extend, due to the limitation of the side wall of the ridge, the mounting frame 401 will drive the guide roller 300 to rotate relative to the telescopic mechanism 400, so that the guide roller 300 rotates until the inclination direction of its axis is roughly parallel to the inclination direction of the side wall of the ridge, thereby facilitating the outer wall of the guide roller 300 to fit tightly against the side wall of the ridge.

[0054] That is, even if the width of the ditch is different and the inclination angle of the ditch side wall is different, by manipulating the telescopic mechanism 400, the side wall of the guide roller 300 can be naturally fitted to the side wall of the ditch without the need to additionally set an angle adjustment mechanism to adjust the inclination angle of the guide roller 300. The structure is simpler, the manufacturing is more convenient, the cost is lower, the operation is more convenient, and the practicality is better.

[0055] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, the hinged position of the mounting frame 401 and the telescopic mechanism 400 is located in the middle of the length direction of the guide roller 300, and pressure sensors 402 are respectively provided between the two ends of the guide roller 300 and the mounting frame 401. The two pressure sensors 402 are respectively used to detect the pressure applied by the side wall of the ditch to the two ends of the guide roller 300. For example, the mounting frame 401 can be provided with a mounting hole corresponding to the guide roller 300, and the two ends of the guide roller 300 are rotatably installed in the mounting hole. The pressure sensor 402 can be provided on the mounting frame 401 and located on the side of the mounting hole away from the side wall of the ditch. When the two ends of the guide roller 300 are subjected to the pressure applied by the side wall of the ditch, pressure will be applied to the side of the mounting hole away from the side wall of the ditch. The pressure sensor 402 can then sense and send a signal to the controller, and the controller controls the telescopic mechanism 400 to perform a corresponding action. During the extension process of the telescopic mechanism 400, generally one end of the guide roller 300 contacts the side wall of the ditch first, and the pressure on the end of the guide roller 300 contacting the side wall of the ditch is relatively small. When the telescopic mechanism 400 continues to extend until the side wall of the guide roller 300 fits the side wall of the ditch as a whole, the pressure on the side wall of the ditch on both ends of the guide roller 300 is approximately equal and greater than a preset value.

[0056] In this embodiment, the pressure sensor 402 can be electrically connected to the controller in the frame 100. When the telescopic mechanism 400 is telescoped to the point where the two pressure sensors 402 detect that the pressure exerted by the side walls of the ditch on both ends of the guide roller 300 is approximately equal and greater than a preset value, the pressure sensor 402 sends a signal to the controller, and the controller controls the telescopic mechanism 400 to stop extending. In this way, the guide roller 300 can be kept in a state where its outer side wall naturally fits against the side wall of the ditch. This can not only prevent the gap between the guide roller 300 and the side wall of the ditch from being too large, causing the frame 100 to be unstable, but also prevent the guide roller 300 from fitting too closely against the side wall of the ditch and affecting the movement of the frame 100, thereby improving practicality.

[0057] In some embodiments of the present invention, Figure 1As shown, the second distance measuring sensor 102 is provided on both sides of the frame 100 in the left and right directions. The second distance measuring sensor 102 is used to detect the distance between itself and the side wall of the ditch in the left and right directions of the frame 100. The second distance measuring sensor 102 can be electrically connected to the controller in the frame 100. In addition to controlling the extension and retraction of the telescopic mechanism 400 by sensing the pressure on the guide roller 300 through the pressure sensor 402, the distance between the side wall of the ditch and the second distance measuring sensor 102 can also be detected by the second distance measuring sensor 102. The controller can control the extension amount of the telescopic mechanism 400 according to the distance information detected by the second distance measuring sensor 102, so that the guide roller 300 is kept in a state where its outer side wall naturally fits the side wall of the ditch, which can not only avoid the gap between the guide roller 300 and the side wall of the ditch being too large to cause the frame 100 to be unstable, but also avoid the guide roller 300 and the side wall of the ditch being too closely fitted to affect the walking of the frame 100, and the practicality is better.

[0058] It should be noted that there are various types of the second distance measuring sensor 102 , for example, it may be an infrared distance measuring sensor, an ultrasonic distance measuring sensor, a radar or other suitable distance measuring sensors.

[0059] In some embodiments of the present invention, Figure 1 As shown, the walking mechanism 200 includes a first drive motor and at least two walking wheels 201, at least two walking wheels 201 are arranged along the front and rear direction of the frame 100, and the first drive motor is connected to one of the walking wheels 201. For example, there can be two walking wheels 201, one of which can be a driving wheel and can be arranged at the rear end of the frame 100, and the other walking wheel 201 can be a driven wheel and can be arranged at the front end of the frame 100, and the first drive motor is arranged on the frame 100 and can be connected to the driving wheel. When the first drive motor is started, the first drive motor can control the driving wheel to rotate, and the driving wheel can then drive the driven wheel to rotate, thereby driving the frame 100 to travel, and at least two walking wheels 201 only form one row and are arranged along the front and rear direction of the frame 100, so that it can be just suitable for the ridges of tobacco fields with narrow bottom ends, and the practicality is better.

[0060] It should be noted that, in some other embodiments of the present invention, the walking mechanism 200 may also include a first drive motor and a crawler track, which is provided on the frame 100 and extends along the front and rear directions of the frame 100, and the first drive motor is connected to the crawler track. When the first drive motor is started, the first drive motor can drive the crawler track to move, and the crawler track thereby drives the frame 100 to move, and the walking mechanism 200 is only provided with one crawler track, so that it can be just suitable for the ridges of tobacco fields with narrow bottom ends, and is more practical.

[0061] In some embodiments of the present invention, Figure 1As shown, the frame 100 includes a vehicle box 103, a bogie 104 and a second drive motor, the bogie 104 is rotatably mounted on the front end of the vehicle box 103 around a vertical axis, one of the running wheels 201 is arranged on the bogie 104, and at least one guide roller 300 in each set of guide rollers 300 is arranged on the bogie 104, and the second drive motor is arranged on the vehicle box 103 and connected to the bogie 104 to control the rotation of the bogie 104. For example, the driven wheel in the running wheel 201 may be arranged on the bogie 104, when the furrow of the tobacco field is bent, the second drive motor is started, and the second drive motor controls the bogie 104 to rotate, thereby adjusting the running direction of the frame 100, and at least one guide roller 300 in each set of guide rollers 300 is arranged on the bogie 104, so that even if the front end of the frame 100 turns, it can still be kept stable by the guide rollers 300 on the bogie 104.

[0062] In some embodiments of the present invention, Figures 1 to 5 As shown, baffles 105 are respectively provided on both sides of the top of the frame 100, and a placement groove is formed between the two baffles 105. The top of the baffle 105 is rotatably connected to a pressing plate 106, and a wrapping cloth 500 is laid in the placement groove. Adhesive tapes 501 are provided on both sides of the wrapping cloth 500, and the two sides of the wrapping cloth 500 are respectively laid on one end of the two pressing plates 106 away from the baffle 105 or bonded to one end of the two pressing plates 106 away from the baffle 105, and the two pressing plates 106 can be rotated in opposite directions until the two adhesive tapes 501 are bonded to each other. For example, when collecting tobacco leaves, the pressing plate 106 can be in a vertical state, the wrapping cloth 500 is laid in the placement groove between the two baffles 105, and the two sides of the wrapping cloth 500 are respectively placed on the top of the two pressing plates 106 or bonded to the top of the two pressing plates 106. When the tobacco leaves are filled with the wrapping cloth 500, the two pressing plates 106 are rotated in opposite directions to a nearly horizontal state. The two pressing plates 106 can flatten the tobacco leaves neatly, and the two adhesive tapes 501 can just be bonded to each other, so that it is convenient for the harvesters to take all the tobacco leaves out of the frame 100.

[0063] It should be noted that, in order to facilitate the harvesters to take out the wrapping cloth 500, handles 502 may be provided on both sides of the wrapping cloth 500.

[0064] In some embodiments of the present invention, an elastic reset member is provided between the pressing plate 106 and the baffle 105, and the elastic reset member is used to keep the pressing plate 106 in a vertical state. For example, the elastic reset member can be a torsion spring, and the two ends of the torsion spring are respectively connected to the pressing plate 106 and the baffle 105. The torsion spring can keep the pressing plate 106 in a vertical state through its own elastic restoring force, that is, the surface of the pressing plate 106 in the thickness direction is in a vertical state, so that it is not only convenient to lay the wrapping cloth 500, but also convenient to place tobacco leaves, and the practicality is better.

[0065] According to the harvesting method of the second embodiment of the present invention, based on the tobacco leaf harvesting transporting equipment of the first embodiment, the harvesting method comprises:

[0066] The tobacco leaf harvesting carrying device is placed in the furrow of the tobacco leaf field, and the outer side walls of the two sets of guide rollers 300 are respectively attached to the two side walls of the furrow;

[0067] The harvesters move along the length of the furrow and pick tobacco leaves on both sides of the furrow, and place the picked tobacco leaves on the frame 100;

[0068] When the harvester is located in front of the frame 100 and the distance value detected by the first distance measuring sensor 101 is greater than the first preset value, the walking mechanism 200 is started to drive the frame 100 to move forward;

[0069] When the harvester is located behind the frame 100 and the distance value detected by the first distance measuring sensor 101 is greater than the second preset value, the traveling mechanism 200 stops running and the frame 100 stops moving forward.

[0070] By adopting the above-mentioned harvesting method, the transporting equipment for tobacco leaf harvesting is not only convenient for walking in the narrow furrow at the bottom, but also will not roll over and has better stability. In addition, the transporting equipment for tobacco leaf harvesting can move itself to the vicinity of the harvesters, making it more convenient to use.

[0071] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
