Description

Technical Field

[0001] The present disclosure relates to the field of control technologies, and more particularly, to a post-harvest transmission device and system for watermelons and melons, as well as a control method therefor. Background Art

[0002] In traditional agricultural production, the harvesting and transportation of watermelons and melons (including but not limited to oval melon crops such as watermelons, melons, and Hami melons) often rely on manual operations. This process not only has a high labor intensity and high labor costs, but also has low efficiency and is prone to damaging the watermelons and melons, affecting their storage time and market sales. With the development of agricultural mechanization, various automated and semi-automated harvesting and transmission devices have been gradually developed to improve the harvesting efficiency and reduce post-harvest losses.

[0003] Currently, in related post-harvest transmission devices for watermelons and melons, due to the oval shape of the watermelons and melons, they are extremely prone to rolling during loading or transmission, and their rolling process cannot be effectively controlled. As a result, there is a risk that the watermelons and melons may collide with each other, collide with the post-harvest transmission device, or even slip off the post-harvest transmission device, resulting in a still relatively high damage rate of the watermelons and melons and even affecting the transmission efficiency.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0005] An object of embodiments of the present disclosure is to provide a post-harvest transmission device and system for watermelons and melons, as well as a control method therefor, which can effectively control and adjust the rolling speed and rolling angle of watermelons and melons during the entire post-harvest transmission process, reduce the damage rate of watermelons and melons during the post-harvest transmission process, and improve the post-harvest transmission efficiency.

The control unit controls the speed and angle of the watermelons and honeydew melons during the transmission process by transmitting control instructions. On the one hand, by controlling the inclination angle of the bearing platform through the angle adjustment unit on the transmission trolley, the rolling speed and rolling angle of the watermelons and honeydew melons on the bearing platform can be controlled, so that the watermelons and honeydew melons are in a stable state and a safe area, avoiding the problem of uncontrollable rolling and damage of the watermelons and honeydew melons during the transmission process, improving the stability of the watermelons and honeydew melons during the transmission process, and reducing the damage rate of the watermelons and honeydew melons. On the other hand, the loading and storage platform adjusts the connection inclination angle between the loading and storage platform and the transmission track body through the speed adjustment unit to control the smooth conveyance of the watermelons and honeydew melons onto the bearing platform at a preset speed range, avoiding damage caused by collisions when manually placing the watermelons and honeydew melons, or damage caused by the watermelons and honeydew melons slipping due to inaccurate placement on the bearing platform. Moreover, only by placing the watermelons and honeydew melons on the loading and storage platform can the accurate conveyance of the watermelons and honeydew melons to the accurate position on the bearing platform be completed. While improving the loading and transmission efficiency of the watermelons and honeydew melons, the damage rate of the watermelons and honeydew melons is effectively reduced, thereby improving the post - harvest transportation efficiency of the watermelons and honeydew melons.

[0049] First, in the first aspect of the embodiments of the present disclosure, a post-harvest transmission device for watermelons and melons is provided, which can be used to transmit the harvested watermelons and melons from the melon ridges to a storage area or a storage device for centralized storage, facilitating transportation or management. For example, the harvested watermelons and melons can be transmitted to a transport vehicle for transfer or transportation through the post-harvest transmission device for watermelons and melons; of course, the post-harvest transmission device for watermelons and melons can also be used to transmit the watermelons and melons in the storage area or the storage device to other storage areas or storage devices, or to a watermelon and melon processing device. The application scenarios of the post-harvest transmission device for watermelons and melons in this exemplary embodiment are not specifically limited.

[0050] Next, in combination with Figures 1 to 6 the post-harvest transmission device for watermelons and melons in the embodiments of the present disclosure will be described.

[0051] Refer toFigure 1 and Figure 2 As shown in Figure 2 , the post-harvest transmission device 10 for watermelons and melons may include a transmission track body 11, at least one transmission trolley 12, a loading and storage platform 13, and a control unit 14. Among them:

[0052] At least one transmission trolley 12 may be drivingly connected to the transmission track body 11. The transmission trolley 12 may at least include a carrying platform 121 and an angle adjustment unit 122. The angle adjustment unit 122 may be configured to adjust the tilt angle of the carrying platform 121 according to a transmission control instruction, so that the watermelons and melons on the carrying platform 121 are in a safe area. For example, the safe area may be the central position area on the carrying platform 121. Of course, it may also be an area far from the edge position of the carrying platform 121. This exemplary embodiment does not make special limitations on this.

[0053] The loading and storage platform 13 may be detachably connected to the transmission track body 11. The loading and storage platform 13 may be configured to load watermelons and melons onto the transmission trolley 12 or transfer the watermelons on the transmission trolley 12 to a storage area or a storage device. The loading and storage platform 13 may be provided with a speed adjustment unit. The speed adjustment unit may be configured to adjust the connection tilt angle between the loading and storage platform 13 and the transmission track body 11 according to a transmission control instruction, so as to control the watermelons and melons on the loading and storage platform 13 to be gently conveyed onto the carrying platform 121 within a preset speed range or convey the watermelons and melons on the carrying platform 121 to the storage area or the storage device within a preset speed range.

[0054] The control unit 14 may be communicatively connected to the transmission trolley 12 and the loading and storage platform 13. For example, it may be connected by wire communication or wireless communication. This embodiment is not limited thereto. The control unit 14 may be configured to receive a transmission control instruction transmitted by a remote control host computer and synchronously transmit the transmission control instruction to each transmission trolley and the loading and storage platform in an instant communication manner, so as to control the rolling speed and rolling angle of the watermelons and melons during the transmission process.

[0055] The tilt angle of the carrying platform 121 can be controlled by the angle adjustment unit 122 on the transfer trolley 12, and the rolling speed and rolling angle of the watermelons on the carrying platform 121 can be controlled, so that the watermelons are in a stable state and a safe area, avoiding the problem of uncontrollable rolling and damage of the watermelons during the transfer process, improving the stability of the watermelons during the transfer process, and reducing the damage rate of the watermelons; the loading and storage platform 13 can adjust the connection tilt angle between the loading and storage platform 13 and the transfer track body 11 through the speed adjustment unit, so as to control the watermelons to be gently conveyed onto the carrying platform 121 within a preset speed range, avoiding damage caused by collision when manually placing the watermelons, or damage caused by the watermelons slipping due to inaccurate placement on the carrying platform 121. Moreover, only by placing the watermelons on the loading and storage platform 13 can the watermelons be accurately conveyed to the correct position on the carrying platform 121. While improving the loading and transfer efficiency of the watermelons, the damage rate of the watermelons is effectively reduced, thereby improving the post-harvest transportation efficiency of the watermelons.

[0056] In an exemplary embodiment of the present disclosure, referring to Figure 2 As shown, the transfer trolley 12 may further include a drive connection unit 123, and the drive connection unit 123 may include a connection frame 1233, a transfer drive motor 1232, and a drive roller 1231. The drive roller 1231 and the transfer drive motor 1232 are fixedly connected to the connection frame 1233.

[0057] The transfer drive motor 1232 can drive the drive roller 1231 to rotate through a transmission structure. The transfer trolley 12 can be in transmission connection with the transfer track body 11 through the drive roller 1231. When the drive roller 1231 rotates, it drives the transfer trolley 12 to run along the transfer track body 11.

[0058] The angle adjustment unit 122 can be fixedly connected to the connection frame 1233, and the carrying platform 121 is fixed on the angle adjustment unit 122; wherein, a buffer spring can be provided between the drive roller 1231 and the connection frame 1233, and the transfer drive motor 1232 can receive a transfer control instruction to adjust the output power to control and adjust the transfer speed of the transfer trolley.

[0059] The angle adjustment unit 122 rotatably connected to the carrying platform 121 can accurately control the rolling speed and rolling angle of the watermelons on the carrying platform 121, keep them in a safe position on the carrying platform 121 and effectively stabilize the watermelons, avoid damage caused by the rolling of the watermelons, and reduce the damage rate.

[0060] Due to the relatively heavy weight of the watermelon and melon, it will bring a relatively large load to the post-harvest transmission device 10 of the watermelon and melon. If the centralized drive mode is adopted, it may cause the post-harvest transmission device 10 of the watermelon and melon to bear a relatively large load and thus cannot operate; while in the embodiment of the present disclosure, the watermelon and melon are transported by the transport trolley 12 that is in transmission connection with the transmission track body 11, and each transport trolley 12 has an independent power source, which can provide a relatively large driving force for the watermelon and melon with a relatively heavy load. Compared with the centralized drive, the driving effect is better and the transport stability is better.

[0061] Optionally, referring to Figure 2 As shown, the angle adjustment unit 122 may include a gyroscope 1222, a plurality of angle adjustment rods 1221 and an angle drive motor 1223. The angle adjustment rod 1221 may be movably connected to one side of the bearing platform 121 close to the connecting frame 1233. The angle drive motor 1223 may be connected to the angle adjustment rod 1221 through a transmission structure. When the angle drive motor 1223 rotates, each angle adjustment rod 1221 drives the bearing platform 121 to tilt. The angle drive motor 1223 may receive the transmission control instruction sent by the control unit 14 to adjust the tilt angle of the bearing platform 121.

[0062] The gyroscope 1222 may collect the tilt angle of the bearing platform 121 in real time. When it detects that the current tilt angle reaches the target tilt angle in the transmission control instruction, it feeds back a target achievement signal to the angle drive motor 1223 to control the angle drive motor 1223 to stop adjusting the tilt angle of the bearing platform 121.

[0063] Through the angle adjustment unit 122 having the gyroscope 1222, a plurality of angle adjustment rods 1221 and the angle drive motor 1223, precise control of the tilt angle of the bearing platform 121 can be achieved. For example, the angle drive motor 1223 may be a servo motor and is controlled by a PID controller, and in combination with a plurality of angle adjustment rods 1221, adjustment of any tilt angle of the bearing platform 121 can be achieved, improving the accuracy and precision of tilt angle control; at the same time, the current adjusted tilt angle is detected in real time through the gyroscope 1222, and when the gyroscope 1222 monitors that the target tilt angle is reached, the angle drive motor 1223 is timely fed back to stop, further improving the control accuracy of the tilt angle of the bearing platform 121.

[0064] Optionally, referring to Figure 2As shown, the transfer trolley 12 may include at least two electromagnetic connection units 124, which may be respectively arranged on both sides of the transfer trolley 12 along the running direction of the transfer track body (such as the direction of X). The electromagnetic connection unit 124 may be used to perform electromagnetic connection with adjacent transfer trolleys 12 or operate independently according to transfer control instructions; the transfer trolley 12 may further include an elastic buffer unit (not shown in the figure). For example, the elastic buffer unit may be an elastic balloon or a rubber ball, and this embodiment does not make special limitations on this. The elastic buffer unit may be used to buffer the collision force generated by the electromagnetic connection of the electromagnetic connection units between the transfer trolleys 12.

[0065] By means of the electromagnetic connection units 124 arranged on both sides of the transfer trolley 12, multiple transfer trolleys 12 can be electromagnetic-connected at any time to achieve the sharing of driving forces among multiple transfer trolleys 12. In this way, when the power of a certain transfer trolley 12 is insufficient or the load is large, the adjacent transfer trolley 12 can be electromagnetic-connected in time, and the adjacent transfer trolley 12 can supply driving force to the current transfer trolley 12, effectively improving the running stability of the transfer trolley 12 and increasing the transportation load of the post-harvest transfer device 10 for watermelons and melons.

[0066] The provided elastic buffer unit can be used to buffer the collision force generated by the electromagnetic connection of the electromagnetic connection units between the transfer trolleys 12, reduce the impact force during the electromagnetic connection of the transfer trolleys 12, thereby effectively ensuring the stability of the watermelons and melons transported on the transfer trolley 12, avoiding damage to the watermelons and melons caused by rolling due to the impact force, and reducing the damage rate of the watermelons and melons.

[0067] In an alternative embodiment of the present disclosure, with reference to Figure 1 As shown, the transfer track body 11 may be composed of multiple track body segments, and the track body segments are rotatably connected to each other, and the length of the track body segment is greater than the length of the transfer trolley 12; both ends of the transfer track body 11 may further include a folding drive unit (not shown in the figure). For example, the folding drive unit may be a drive wheel arranged at both ends of the transfer track body 11, and the folding drive unit may be used to generate driving forces at both ends of the transfer track body according to the received transfer control instructions, so as to fold multiple track body segments.

[0068] By setting the transmission track body 11 as multiple track body segments, and connecting the multiple track body segments through turning structures, the folding of the post-harvest transmission device 10 for watermelons and melons can be achieved, saving storage space and ensuring the portability of the post-harvest transmission device 10 for watermelons and melons during handling. Thus, to a certain extent, the transmission efficiency of watermelons and melons can be improved; by setting the length of the track body segment to be greater than the length of the transmission trolley 12, the track body segment can protect the transmission trolley 12 during folding, reduce the damage rate of the transmission trolley 12, and can improve the folding success rate of the transmission track body 11; by setting the folding drive units on both sides of the transmission track body 11, the folding of the post-harvest transmission device 10 for watermelons and melons can be automatically completed, improving the folding efficiency.

[0069] In an alternative embodiment of the present disclosure, referring to Figure 3 As shown, the loading and storage platform 13 may include a loading platform 131. Specifically, the loading platform 131 may include an annular support frame 1311, a first lifting platform 1312, and elastic net ropes 1313. One end of the annular support frame 1311 may be fixed to the loading end of the transmission track body 11 through a fixing member. The first lifting platform 1312 may be fixed to the end of the annular support frame 1311 away from the transmission track body 11. The elastic net ropes 1313 may be supported and fixed inside the annular support frame 1311.

[0070] Among them, the first lifting platform 1312 may be a speed adjustment unit, specifically used to adjust the lifting height of one end of the annular support frame 1311 according to the transmission control instruction, so as to control the tilt angle of the loading platform 131 through the lifting height, and thus control the watermelons on the loading platform 131 to be gently conveyed onto the bearing platform 121 at a preset speed range.

[0071] Through the loading platform 131, the watermelons can be quickly and accurately placed on the bearing platform 121, effectively improving the loading efficiency of watermelons; and through the structures of the annular support frame 1311, the first lifting platform 1312, and the elastic net ropes 1313, the damage rate of watermelons during loading can be effectively reduced, and the rolling speed of watermelons is controlled and adjusted by the first lifting platform 1312, thereby further improving the safety of watermelons, reducing the risk of watermelons being damaged or rolling down, and reducing the damage rate.

[0072] In an alternative embodiment of the present disclosure, referring to Figure 4As shown, the loading and storage platform 13 may include a storage platform 132. The storage platform 132 may include a second lifting platform 1321 and an elastic cylindrical mesh bag 1322. Among them, the second lifting platform 1321 may be a speed adjustment unit. The second lifting platform 1321 and the elastic cylindrical mesh bag 1322 may be fixedly connected to the storage end of the transmission track body 11. The second lifting platform 1321 may be used to adjust the height of the storage end of the transmission track body 11 according to the transmission control instruction to control and adjust the speed at which the watermelons transported on the transmission trolley 12 fall into the elastic cylindrical mesh bag 1322. The elastic cylindrical mesh bag 1322 may be used to wrap the watermelons and transfer the watermelons to the storage area or storage device of the watermelons at a gentle speed.

[0073] By controlling and adjusting the speed at which the watermelons transported on the transmission trolley 12 fall into the elastic cylindrical mesh bag 1322 through the second lifting platform 1321, the rolling speed of the watermelons falling into the storage area or storage device can be adjusted, reducing the damage rate. At the same time, by wrapping the watermelons with the elastic cylindrical mesh bag 1322 and transferring them to the storage area or storage device of the watermelons at a gentle speed, the damage risk of the watermelons is further reduced, and the safety of the watermelons during transportation is improved.

[0074] In an alternative embodiment of the present disclosure, refer to Figure 5 and Figure 6 As shown, the bearing platform 121 may include a bearing plate body 1211, a plurality of buffer bearing columns 1212, and an elastic buffer layer 1213. Among them:

[0075] The bearing plate body 1211 may include a plurality of uniformly distributed receiving holes 1214. A plurality of buffer bearing columns 1212 may be disposed in the receiving holes 1214 and fixedly connected to the bottom of the receiving holes 1214 through buffer springs 1215. The elastic buffer layer 1213 may be laid on one end of the plurality of buffer bearing columns 1212 away from the bearing plate body 1211. Among them, when watermelons roll over the plurality of buffer bearing columns 1212 and the elastic buffer layer 1213, a shape depression adapted to the watermelons is formed to limit the rolling of the watermelons.

[0076] By providing the plurality of buffer bearing columns 1212 and the elastic buffer layer 1213, the buffering of the watermelons rolling from the loading platform 131 can be effectively achieved, further reducing the risk of damage or slipping of the watermelons. At the same time, the plurality of buffer bearing columns 1212 and the elastic buffer layer 1213 can also form a shape depression adapted to the watermelons to limit the rolling of the watermelons, thereby effectively improving the stability of the watermelons on the bearing platform 121 during transmission.

[0077] In summary, according to the post - harvest transmission device for watermelons and melons in the disclosed embodiments, there are provided a transmission track body, at least one transmission trolley, a loading and storage platform, and a control unit. Among them, the transmission trolley includes a bearing platform and an angle adjustment unit, which can keep the watermelons and melons on the bearing platform within a safe area. The loading and storage platform adjusts the connection inclination angle between the loading and storage platform and the transmission track body through a speed adjustment unit to control the watermelons and melons to be gently conveyed onto the bearing platform within a preset speed range. The control unit controls the speed and angle of the watermelons and melons during the transmission process by transmitting control instructions. On the one hand, by controlling the inclination angle of the bearing platform through the angle adjustment unit on the transmission trolley, the rolling speed and rolling angle of the watermelons and melons on the bearing platform can be controlled, so that the watermelons and melons are in a stable state and a safe area, avoiding the problem of uncontrollable rolling and damage of the watermelons and melons during the transmission process, improving the stability of the watermelons and melons during the transmission process, and reducing the damage rate of the watermelons and melons. On the other hand, the loading and storage platform adjusts the connection inclination angle between the loading and storage platform and the transmission track body through the speed adjustment unit to control the watermelons and melons to be gently conveyed onto the bearing platform within a preset speed range, avoiding the damage caused by collision when manually placing the watermelons and melons, or the problem of damage caused by the watermelons and melons slipping due to inaccurate placement on the bearing platform. And only by placing the watermelons and melons on the loading and storage platform can the accurate position of the watermelons and melons on the bearing platform be completed. While improving the loading and transmission efficiency of the watermelons and melons, the damage rate of the watermelons and melons is effectively reduced, thus improving the post - harvest transportation efficiency of the watermelons and melons.
