[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] This embodiment provides a field transport vehicle for picking, such as Figure 1-Figure 4As shown, it includes a vehicle body 1, a support plate 3, a lifting assembly 4, a sensor 5 and a control module 6. The vehicle body 1 is provided with a receiving groove 2, and the receiving groove 2 extends from the upper end surface of the vehicle body 1 to the lower end surface of the vehicle body 1; the support plate 3 is slidably arranged in the receiving groove 2; the lifting assembly 4 is arranged on the vehicle body 1, and the lifting assembly 4 is connected to the support plate 3; the sensor 5 is arranged at the notch of the receiving groove 2, and the sensor 5 is used to detect whether there is a target object at the notch of the receiving groove 2; if the sensor 5 detects that there is a target object at the notch of the receiving groove 2, a first target signal is generated; if the sensor 5 does not detect .... If there is a target object at the slot of the slot 2, a second target signal is generated; the control module 6 is connected to the sensor 5 and the lifting assembly 4, and the control module 6 is used to receive work instructions; if the control module 6 receives a loading work instruction, then when the control module 6 obtains the first target signal from the sensor 5, the control module 6 controls the lifting assembly 4 to drive the support plate 3 to descend along the slot of the slot 2 toward the bottom of the slot 2; if the control module 6 receives a unloading work instruction, then when the control module 6 obtains the second target signal, the control module 6 controls the lifting assembly 4 to drive the support plate 3 to rise along the bottom of the slot 2 toward the slot of the slot 2.

[0030] Exemplarily, during implementation, an upper end surface of the vehicle body 1 is provided with a receiving groove 2 , and the receiving groove 2 extends from the upper end of the vehicle body 1 toward the lower end of the vehicle body 1 .

[0031] The support plate 3 is slidably disposed in the receiving groove 2, so that the support plate 3 can move along the groove opening of the receiving groove 2 toward the groove bottom of the receiving groove 2. In other words, the support plate 3 can slide upward / downward along the receiving groove 2.

[0032] The lifting assembly 4 can be an electric telescopic rod, a hydraulic telescopic rod, a telescopic cylinder or other telescopic mechanisms. The lifting assembly 4 is installed at the bottom of the receiving groove 2, and the upper end of the lifting assembly 4 is connected to the lower plate surface of the support plate 3. When the lifting assembly 4 is extended, the support plate 3 can be driven to move upward along the direction from the bottom of the receiving groove 2 to the notch of the receiving groove 2; when the lifting assembly 4 is retracted, the support plate 3 can be driven to move downward along the direction from the notch of the receiving groove 2 to the bottom of the receiving groove 2.

[0033] The sensor 5 is connected to the notch of the receiving groove 2 by screwing, clamping with a clamping piece, etc. The sensor 5 is used to detect in real time whether there is a target object at the notch of the receiving groove 2. The target object can be a crop such as eggplant, tomato, radish, etc. When the sensor 5 detects that there is a target object at the notch of the receiving groove 2, the sensor 5 generates a first target signal; when the sensor 5 does not detect that there is a target object at the notch of the receiving groove 2, the sensor 5 generates a second target signal.

[0034] The control module 6 is arranged on the vehicle body 1, and the control module 6 is electrically connected to the sensor 5 and the lifting assembly 4. By arranging a mobile power source such as a lithium battery or a lead-acid battery on the vehicle body 1, and connecting the mobile power source, the control module 6, the sensor 5, and the lifting assembly 4 through a wire, the electrical connection between the control module 6, the sensor 5, and the lifting assembly 4 can be realized. The control module 6 is used to receive work instructions. When the control module 6 receives a work instruction for loading, the control module 6 obtains the signal generated by the sensor 5 in real time. When the control module 6 obtains the first target signal generated by the sensor 5, the control module 6 generates a control instruction to control the lifting assembly 4 to drive the support plate 3 to move downward along the notch of the receiving groove 2 to the bottom of the receiving groove 2; when the control module 6 receives a work instruction for unloading, the control module 6 obtains the signal generated by the sensor 5 in real time. When the control module 6 obtains the second target signal generated by the sensor 5, the control module 6 generates a control instruction to control the lifting assembly 4 to drive the support plate 3 to move upward along the bottom of the receiving groove 2 to the notch of the receiving groove 2.

[0035] During use, when the target object needs to be loaded into the receiving tank 2, the field transfer vehicle is first initialized so that the control module 6 controls the lifting assembly 4 to drive the support plate 3 to move upward to the initial loading position along the direction from the bottom of the receiving tank 2 to the notch of the receiving tank 2, and at the same time, the sensor 5 detects in real time whether there is a target object at the notch of the receiving tank 2. Secondly, the loading work instruction is sent to the control module 6. When the control module 6 receives the loading work instruction, the control module 6 obtains the signal generated by the sensor 5 in real time. As the target object is put in, the target object gradually accumulates on the support plate 3. When the target object on the support plate 3 is piled to the notch of the receiving tank 2, the sensor 5 detects that there is a target object at the notch of the receiving tank 2 and generates a first target signal. When the control module 6 obtains the first target signal, the control module 6 generates a descending instruction. In response to the descending instruction, the lifting assembly 4 drives the support plate 3 to move downward a certain distance along the notch of the receiving tank 2 to the bottom of the receiving tank 2 until the target object on the support plate 3 is located below the notch of the receiving tank 2. In this way, several objects can be placed in the receiving groove 2. By adjusting the height of the support plate 3, it is expected that the crops can be placed in the vehicle body 1 with the least damage, thereby reducing the damage to the crops and improving the quality of the crops.

[0036] When the target object needs to be taken out from the receiving tank 2, the work instruction of unloading is sent to the control module 6. When the control module 6 receives the work instruction of unloading, the control module 6 obtains the signal generated by the sensor 5 in real time. When the target object on the support plate 3 does not appear in the notch of the receiving tank 2, the sensor 5 does not detect the existence of the target object in the notch of the receiving tank 2, and generates a second target signal. When the control module 6 obtains the second target signal, the control module 6 generates an ascending instruction. The lifting component 4 responds to the ascending instruction to drive the support plate 3 to move downward a certain distance along the notch of the receiving tank 2 toward the bottom of the receiving tank 2 until the target object on the support plate 3 appears in the notch of the receiving tank 2. It is expected to achieve the purpose of gradually pushing the crops in the receiving tank 2 to the notch of the receiving tank 2, thereby facilitating the removal of the bottom crops.

[0037] When the control module 6 receives the work instruction of loading, it obtains the first target signal that the sensor 5 detects the existence of the target object in the slot of the receiving slot 2; when the control module 6 receives the work instruction of unloading, it obtains the second target signal that the sensor 5 does not detect the existence of the target object in the slot of the receiving slot 2. It is expected that the control module 6 can obtain different target signals under different work instructions, thereby reducing the risk of the control module 6 mistakenly controlling the lifting and lowering of the lifting assembly 4.

[0038] In a preferred embodiment, during the process of loading the crops, the crops will pass through the notch of the receiving tank 2. At this time, the sensor 5 will detect the presence of the target object at the notch of the receiving tank 2, and then generate the first target signal. Therefore, in order to reduce the risk of false alarms of the sensor 5, the sensor 5 can be made to continuously detect the presence of the target object at the notch of the receiving tank 2 for a certain period of time before generating the first target signal. In order to achieve the purpose of reducing the risk of false alarms of the sensor 5.

[0039] During the process of loading the target object, when the target object at a certain position of the support plate 3 is stacked to the notch of the receiving groove 2, the sensor 5 will detect the presence of the target object at the notch of the receiving groove 2 and generate a first target signal. At this time, the target objects at other positions on the support plate 3 are not stacked to the notch of the receiving groove 2. In this state, if the control module 6 controls the lifting assembly 4 to drive the support plate 3 to move downward along the notch of the receiving groove 2 toward the bottom of the receiving groove 2, the risk of the target object being damaged during the falling process will increase when the target object is subsequently loaded to other positions on the support plate 3. Therefore, in order to further reduce the risk of the target object falling during the falling process. In this embodiment, if Figure 1As shown, the number of the sensors 5 is set to be several, and the several sensors 5 are arranged around the axis of the receiving groove 2; if the control module 6 receives a loading work instruction, then when the control module 6 obtains the first target signal of each sensor 5, the control module 6 controls the lifting assembly 4 to drive the support plate 3 to descend along the notch of the receiving groove 2 toward the bottom of the receiving groove 2; if the control module 6 receives a unloading work instruction, then when the control module 6 obtains the second target signal of each sensor 5, the control module 6 controls the lifting assembly 4 to drive the support plate 3 to rise along the bottom of the receiving groove 2 toward the notch of the receiving groove 2.

[0040] Exemplarily, in the implementation process, the number of sensors 5 is set to be several, and the several sensors 5 are arranged around the axis of the receiving groove 2 and at the notch of the receiving groove 2 .

[0041] During use, when the control module 6 receives the work instruction of loading, the control module 6 obtains the signals generated by each sensor 5 in real time. As the target objects are put in, the target objects gradually accumulate on the support plate 3. When the target objects at a certain position of the support plate 3 are stacked to the notch of the receiving groove 2, some sensors 5 can detect the existence of the target objects at the notch of the receiving groove 2 and generate the first target signal. When the target objects at each position of the support plate 3 are stacked to the notch of the receiving groove 2, each sensor 5 can detect the existence of the target objects at the notch of the receiving groove 2 and generate the first target signal. When the control module 6 obtains the first target signal of each sensor 5, the control module 6 generates a descending instruction. The lifting component 4 responds to the descending instruction to drive the support plate 3 to move downward a certain distance along the notch of the receiving groove 2 toward the bottom of the receiving groove 2 until the target objects on the support plate 3 are located below the notch of the receiving groove 2. In this way, a number of target objects can be loaded into the receiving groove 2. Multiple sensors 5 are used to detect the status of each position of the slot of the accommodating groove 2, in order to ensure that the lowering operation is performed only when there is a target object at each position on the support plate 3, thereby reducing the risk of local accumulation causing the target object to be damaged during the falling process, so as to improve the quality of the target object.

[0042] When the control module 6 receives the work instruction of unloading, the control module 6 obtains the signal generated by the sensor 5 in real time. When the target at a certain position of the support plate 3 is taken out, some sensors 5 do not detect the existence of the target at the notch of the receiving groove 2, and generate a second target signal. When the target at each position of the support plate 3 is taken out, each sensor 5 does not detect the existence of the target at the notch of the receiving groove 2, and generates a second target signal. When the control module 6 obtains the second target signal of each sensor 5, the control module 6 generates an ascending instruction. The lifting component 4 responds to the ascending instruction to drive the support plate 3 to move downward a certain distance along the notch of the receiving groove 2 toward the bottom of the receiving groove 2 until the target on the support plate 3 appears at the notch of the receiving groove 2. Multiple sensors 5 are used to detect the state of each position of the notch of the receiving groove 2, in order to ensure that the ascending operation is performed only when there is no target at each position on the support plate 3, thereby reducing the risk of slipping during the ascending process of the support plate 3 when the locally accumulated target is not removed in time, so as to improve the quality of the target.

[0043] If the lifting assembly 4 is an electric telescopic rod, a pneumatic telescopic rod, a cylinder, etc., and is installed at the bottom of the receiving groove 2, the height of the lifting assembly 4 itself will greatly reduce the loading amount of the target object in the receiving groove 2. Therefore, in order to increase the loading amount of the target object in the receiving groove 2. In this embodiment, Figure 3 As shown in combination 4, the lifting assembly 4 includes a driving motor 41 and a threaded rod 42; the threaded rod 42 is rotatably connected to the bottom of the accommodating groove 2, the threaded rod 42 extends along the bottom of the accommodating groove 2 toward the notch of the accommodating groove 2, and the threaded rod 42 is screwed to the support plate 3; the driving motor 41 is arranged on the vehicle body 1, and the driving motor 41 is connected to the threaded rod 42.

[0044] Exemplarily, during implementation, the lifting assembly 4 includes a driving motor 41 and a threaded rod 42 .

[0045] The threaded rod 42 is disposed in the receiving groove 2, and extends from the groove opening of the receiving groove 2 toward the groove bottom of the receiving groove 2, and the threaded rod 42 is rotatably connected to the groove bottom of the receiving groove 2 by means of bearings, shaft holes, etc.

[0046] The support plate 3 is screwed onto the threaded rod 42 .

[0047] The drive motor 41 is installed on the vehicle body 1 by screwing, clamping, etc. The output shaft of the drive motor 41 is connected to the threaded rod 42 through a coupling, gear or other transmission mechanism, and the drive motor 41 is electrically connected to the control module 6.

[0048] When the control module 6 generates a descending command, the driving motor 41 responds to the descending command and rotates in the clockwise direction, driving the threaded rod 42 to rotate. When the threaded rod 42 rotates, the support plate 3 moves downward a certain distance along the notch of the accommodating groove 2 toward the bottom of the accommodating groove 2 under the action of the limit of the accommodating groove 2.

[0049] When the control module 6 generates an ascending instruction, the driving motor 41 responds to the ascending instruction and rotates in the counterclockwise direction, driving the threaded rod 42 to rotate. When the threaded rod 42 rotates, the support plate 3 moves upward a certain distance along the bottom of the receiving groove 2 toward the notch of the receiving groove 2 under the action of the position limit of the receiving groove 2. On the one hand, the purpose of using the driving motor 41 to drive the threaded rod 42 to rotate to drive the support plate 3 to rise / fall is achieved. On the other hand, the purpose of significantly reducing the height occupied by the lifting component 4 itself is achieved, thereby increasing the effective loading space of the receiving groove 2, and further increasing the loading amount of crops.

[0050] In this embodiment, if Figure 3 As shown, the driving motor 41 is arranged on the lower end surface of the vehicle body 1 .

[0051] For example, in the implementation process, the drive motor 41 is installed on the lower end surface of the vehicle body 1 by screwing, clamping, etc., in order to reduce the installation height of the drive motor 41 and use the weight of the drive motor 41 to improve the overall stability during transportation.

[0052] In order to reduce the risk of the threaded rod 42 contacting the crops and causing damage to the crops. Figure 4 As shown, a slide groove 7 is provided on the side wall of the accommodating groove 2; the slide groove 7 extends along the notch of the accommodating groove 2 toward the bottom of the accommodating groove 2, and the upper groove wall and the lower groove wall of the slide groove 7 are rotatably connected to the upper end and the lower end of the threaded rod 42 respectively; a slider 8 is provided on the side wall of the support plate 3; the slider 8 is adapted in the slide groove 7, and the slider 8 is screwed to the threaded rod 42.

[0053] Exemplarily, in the implementation process, the side wall of the receiving groove 2 is provided with a slide groove 7, and the slide groove 7 extends along the notch of the receiving groove 2 toward the bottom of the receiving groove 2. The threaded rod 42 is arranged in the slide groove 7, and the upper end of the threaded rod 42 is rotatably connected to the upper groove wall of the slide groove 7 by means of a bearing, an axial hole, etc., and the lower end of the threaded rod 42 is rotatably connected to the lower groove wall of the slide groove 7 by means of a bearing, an axial hole, etc., in order to achieve the purpose of improving the stability of the threaded rod 42 when rotating with the driving motor 41. At the same time, the threaded rod 42 is arranged in the slide groove 7 in order to achieve the risk of contact between the threaded rod 42 and the target object in the receiving groove 2 during the rotation of the threaded rod 42, thereby reducing the risk of damage to the target object caused by the threaded rod 42 when rotating, so as to improve the quality of the target object.

[0054] The side wall of the support plate 3 is connected with a slider 8 by welding, screwing or integral molding, and the slider 8 fits into the slide groove 7, and the slider 8 is screwed into the threaded rod 42. It is expected that when the threaded rod 42 rotates, the support plate 3 can be driven to move up and down along the threaded rod 42.

[0055] In order to further reduce the risk of the threaded rod 42 contacting the crops and causing damage to the crops. Figure 4 As shown, the longitudinal cross-sectional area of ​​the slide groove 7 gradually increases along the direction from the groove opening of the slide groove 7 to the groove bottom of the slide groove 7.

[0056] For example, during implementation, the longitudinal cross-sectional area of ​​the chute 7 gradually increases from the slot opening of the chute 7 to the bottom of the chute 7. In other words, the chute 7 is narrower near the slot opening and wider near the bottom of the slot, so as to reduce the risk of the threaded rod 42 contacting the crops and causing damage to the crops.

[0057] In order to further reduce the risk of the threaded rod 42 contacting the crops and causing damage to the crops. Figure 3 As shown, the notch of the accommodating groove 2 is provided with an elastic protective sheet 9 ; the elastic protective sheet 9 blocks the notch of the accommodating groove 2 .

[0058] Exemplarily, during the implementation, the field transport vehicle also includes an elastic protective sheet 9, which is made of a material with good elasticity and wear resistance, such as rubber, silicone or high-strength plastic. One side of the elastic protective sheet 9 is connected to one side of the notch of the chute 7 by means of screws, buckles, adhesives or embedded methods, and the elastic protective sheet 9 extends from the upper end of the chute 7 to the lower end of the chute 7 to cover the notch of the chute 7. The other side of the elastic protective sheet 9 is partially fitted with the slider 8, and the rest is fitted on the other side of the chute 7. When the slider 8 slides in the chute 7, the part of the elastic protective sheet 9 located in front of the sliding direction of the slider 8 moves away from the notch of the chute 7 in sequence along the sliding direction of the slider 8. The part of the elastic protective sheet 9 located behind the sliding direction of the slider 8 is fitted in the notch of the chute 7 in sequence along the sliding direction of the slider 8. On the one hand, by utilizing the elasticity of the elastic protective sheet 9, the portion of the elastic protective sheet 9 located in front of the sliding direction of the slider 8 can be away from the notch of the slide groove 7, and the portion of the elastic protective sheet 9 located in the rear of the sliding direction of the slider 8 can be attached to the notch of the slide groove 7. On the other hand, the elastic protective sheet 9 is used to block the notch of the accommodating groove 2 to form a barrier, so as to further reduce the risk of the threaded rod 42 contacting the crops and causing damage to the crops.

[0059] Example 2

[0060] This embodiment provides a method for using a field transport vehicle for picking, which is applicable to the field transport vehicle described in Embodiment 1, and includes the following operations:

[0061] Using a sensor to detect in real time whether there is a target object at the slot of the receiving slot; if so, a first target signal is generated; if not, a second target signal is generated;

[0062] The control module is used to obtain work instructions in real time; if the control module receives a work instruction for loading, the control module obtains the first target signal generated by the sensor in real time, and when the first target signal is obtained, the lifting component is controlled to drive the support plate to descend along the notch of the receiving groove toward the bottom of the receiving groove; if the control module receives a work instruction for unloading, the control module obtains the second target signal generated by the sensor in real time, and when the second target signal is obtained, the lifting component is controlled to drive the support plate to rise along the bottom of the receiving groove toward the notch of the receiving groove.

[0063] Exemplarily, during the implementation process, when the target object needs to be loaded into the receiving tank, the field transfer vehicle is first initialized so that the control module controls the lifting assembly to drive the support plate to move upward to the initial loading position along the direction from the bottom of the receiving tank to the notch of the receiving tank, and at the same time, the sensor detects in real time whether there is a target object in the notch of the receiving tank. Secondly, the loading work instruction is sent to the control module. When the control module receives the loading work instruction, the control module obtains the signal generated by the sensor in real time. As the target object is put in, the target object gradually accumulates on the support plate. When the target object on the support plate is piled to the notch of the receiving tank, the sensor detects that there is a target object in the notch of the receiving tank and generates a first target signal. When the control module obtains the first target signal, the control module generates a descending instruction. The lifting assembly responds to the descending instruction to drive the support plate to move downward a certain distance along the notch of the receiving tank to the bottom of the receiving tank until the target object on the support plate is located below the notch of the receiving tank. In this way, a number of targets can be loaded into the receiving tank. By adjusting the height of the support plate, it is expected that the crops can be placed into the vehicle body with the least damage, thereby reducing the damage to the crops and improving the quality of the crops.

[0064] When the target object needs to be taken out from the receiving tank, the work instruction of unloading is sent to the control module. When the control module receives the work instruction of unloading, the control module obtains the signal generated by the sensor in real time. When the target object on the support plate does not appear in the notch of the receiving tank, the sensor does not detect the existence of the target object in the notch of the receiving tank, and generates a second target signal. When the control module obtains the second target signal, the control module generates an ascending instruction. The lifting component responds to the ascending instruction to drive the support plate to move downward a certain distance along the notch of the receiving tank toward the bottom of the receiving tank until the target object on the support plate appears in the notch of the receiving tank. It is expected to achieve the purpose of gradually pushing the crops in the receiving tank to the notch of the receiving tank, thereby facilitating the removal of the bottom crops.

[0065] When the control module receives a loading work instruction, it obtains a first target signal indicating that the sensor detects that a target object exists in the slot of the receiving slot; when the control module receives a unloading work instruction, it obtains a second target signal indicating that the sensor does not detect that a target object exists in the slot of the receiving slot. It is expected that the control module can obtain different target signals under different work instructions, thereby reducing the risk of the control module mistakenly controlling the lifting and lowering of the lifting component.

[0066] In a preferred embodiment, during the process of loading the crops, the crops will pass through the notch of the receiving tank. At this time, the sensor will detect the presence of the target object at the notch of the receiving tank, and then generate the first target signal. Therefore, in order to reduce the risk of false alarms by the sensor, the sensor can be made to continuously detect the presence of the target object at the notch of the receiving tank for a certain period of time before generating the first target signal. In order to achieve the purpose of reducing the risk of false alarms by the sensor.
