[0047] Please refer to Figures 1-6 , this embodiment provides a vegetable harvesting device 100, and the vegetable harvesting device 100 includes a mobile vehicle frame 110, a guide wheel assembly 120, a cutting knife 130, an aggregate box 140, and a driving unit 150;

[0048] The mobile frame 110 includes a frame main body 111 and a movable wheel set 112 connected to the frame main body 111. The frame main body 111 is configured with a feed inlet 113, a discharge outlet 114, and a material guiding channel 115. Along the forward direction of the mobile frame 110, the feed inlet 113 and the discharge outlet 114 are respectively located at the front end and the rear end of the frame main body 111, and the material guiding channel 115 connects the feed inlet 113 and the discharge outlet 114.

[0049] The guide wheel assembly 120 is connected to the front end of the frame main body 111 and is used to guide the vegetables to move in the direction of being introduced into the feed inlet 113. The cutter 130 is connected to the front end of the frame main body 111 and is located below the feed inlet 113. The aggregate box 140 is detachably connected to the frame main body 111 and is used to collect the vegetables discharged from the discharge outlet 114.

[0050] Wherein, the drive unit 150 is connected to the frame main body 111 and is in transmission connection with the movable wheel set 112, the guide wheel assembly 120, and the cutter 130.

[0051] Please refer to Figures 1-6 , the working principle of the vegetable harvesting device 100 is as follows:

[0052] First of all, in this embodiment, the harvesting of Chinese cabbages is taken as an example for illustration. Specifically, taking single-row harvesting as an example, during the process of harvesting Chinese cabbages, the drive unit 150 drives the movable wheel set 112 to rotate, so that the vegetable harvesting device 100 moves forward relative to the single planted row.

[0053] During the forward movement, since the front end of the frame main body 111 is configured with a feed inlet 113, and a guide wheel assembly 120 is configured relative to the position of the feed inlet 113, and a cutter 130 is also configured below it. Therefore, during the harvesting process, the Chinese cabbages can be guided by the guide wheel assembly 120 to move in the direction of being introduced into the feed inlet 113, and the rootstocks of the Chinese cabbages are cut off by the cutter 130. Thus, the harvested Chinese cabbages can enter the frame main body 111.

[0054] As the harvesting continues, the Chinese cabbages in the frame main body 111 will move along its material guiding channel 115 from the feed inlet 113 towards the discharge outlet 114. Then, after being discharged from the discharge outlet 114, they are collected into the aggregate box 140 for collection. After the box is full, it is replaced. Moreover, a handle convenient for pushing is configured, and the handle is easy to operate, realizing single-person single-row harvesting.

[0055] Moreover, in the above content, in this embodiment, the drive unit 150 is connected to the frame main body 111 and is in transmission connection with the movable wheel set 112, the guide wheel assembly 120, and the cutter 130. Therefore, the overall structural arrangement can be simplified. At the same time, the drive unit 150 can be powered by a battery to improve the flexibility and convenience of use.

[0056] Moreover, during the harvesting process, the guide wheel can be used to guide the movement of the cabbage, thereby reducing or avoiding damage to the cabbage during the aforementioned harvesting process;

[0057] In summary, the vegetable harvesting device 100 can effectively improve the harvesting efficiency, reduce the damage rate of vegetables, and can also adapt to the harvesting of vegetables of different sizes or types to achieve precise harvesting.

[0058] For further information, please refer to Figures 1-6 In the present embodiment, when configuring the guide wheel assembly 120, the present embodiment adopts that the guide wheel assembly 120 includes a top pressure wheel 121 located above the feed port 113 and two impeller wheels 122 located on both sides of the feed port 113; the top pressure wheel 121 and the two impeller wheels 122 are all connected to the driving unit 150 in transmission.

[0059] The vegetable harvesting device 100 also includes a pressing wheel bracket 123, and the pressing wheel 121 is rotatably connected to the pressing wheel bracket 123; wherein the pressing wheel bracket 123 is movably connected to the frame body 111 along the vertical direction.

[0060] Therefore, through the above-mentioned structural arrangement, a corresponding material guiding function can be formed above and on both sides of the feed port 113, and on this basis, the position of the pressing wheel bracket 123 can be adjusted to further adjust the position of the pressing wheel 121, thereby being able to adapt to the harvesting of cabbages of different sizes.

[0061] Furthermore, when installing the material collecting box 140, in order to improve the flexibility and convenience of its installation, a material discharging rack 116 is disposed at the rear end of the vehicle frame body 111, and the material collecting box 140 can be movably connected to the material discharging rack 116. That is, the material collecting box 140 can be placed on the material discharging rack 116, thereby facilitating the installation and use of the material collecting box 140.

[0062] Please refer to Figures 1-9 On the basis of the above contents, the cabbage in the material guiding channel 115 will continuously move from the feed port 113 to the discharge port 114 in the material guiding channel 115. In this process, in order to reduce or avoid damage to the cabbage, the vegetable harvesting device 100 also includes a conveying component 160 connected to the material guiding channel 115. The conveying component 160 is used to convey vegetables from the feed port 113 to the discharge port 114; wherein the conveying component 160 is transmission-connected to the driving unit 150.

[0063] That is, in this way, the conveying component 160 can be set to convey vegetables from the feed port 113 to the discharge port 114, thereby preventing the cabbages in the guide channel 115 from being squeezed against each other, thereby avoiding or reducing crushing between the cabbages.

[0064] Specifically, in this embodiment, the conveying assembly 160 includes a conveyor belt 161 and two transmission wheels 162; the two transmission wheels 162 are rotatably connected to the frame body 111 and are arranged at intervals along the extension direction of the material guide channel 115; the conveyor belt 161 is sleeved on the two transmission wheels 162, and a plurality of push parts 163 for pushing vegetables are convexly provided on the outer periphery of the conveyor belt 161. Moreover, the plurality of push parts 163 are sequentially arranged at intervals along the extension direction of the conveyor belt 161, and each push part 163 includes a curling belt 164, and the two free ends of the curling belt 164 are connected to the conveyor belt 161.

[0065] Therefore, through the above-mentioned structural arrangement, the conveyor belt 161 and the multiple pushing parts 163 on the conveyor belt 161 can be driven by the driving action of the driving unit 150 to transport vegetables from the feed port 113 to the discharge port 114. When configuring the pushing part 163, since it is a curled belt 164 connected to the conveyor belt 161, it has a certain elasticity and deformation ability, so that it can play the role of pushing the cabbage after contacting the cabbage in the guide channel 115. Since it has its own elasticity and deformation ability, it can avoid damaging the cabbage, and at the same time, it can also increase the contact area with the cabbage by its own deformation, thereby protecting the pushed cabbage. It can also restore to its original shape through its own elasticity after the pushing is completed and the cabbage is out of contact.

[0066] It should be noted that the parts of the pressure wheel 121, the impeller 122 and the conveyor belt 161 that are in contact with the cabbage can be made of flexible materials such as rubber. The blades of the pressure wheel 121 and the impeller 122 can be made of flexible materials such as rubber, or rubber sheets can be set on their edges; and the conveyor belt 161 can be made of flexible materials such as rubber to make the curled belt 164.

[0067] For further information, please refer to Figures 1-10 In this embodiment, it can be seen from the above content that this embodiment adopts the setting of a driving unit 150 to achieve the function of driving the movable wheel group 112, the guide wheel assembly 120, the cutter 130 and the transmission assembly 160; on this basis, the driving unit 150 may include a driving motor 151 and a transmission 152 arranged on the lower side of the frame body 111, and the transmission 152 is connected to the driving motor 151 in a transmission manner;

[0068] That is, the driving unit 150 can drive the driving motor 151 to rotate by means of a built-in battery. On this basis, by means of the transmission 152 being configured with a first output end 153, a second output end 154, a third output end 155 and a fourth output end 156, it can output the same or different torques and rotational speeds, thereby meeting the motion requirements of the movable wheel set 112, the guide wheel assembly 120, the cutting tool 130 and the conveying assembly 160;

[0069] Specifically, the first output end 153 is in transmission connection with the movable wheel set 112, the second output end 154 is in transmission connection with the cutting tool 130, the third output end 155 is in transmission connection with the conveying assembly 160, and the fourth output end 156 is in transmission connection with the guide wheel assembly 120; Thus, the movable wheel set 112, the guide wheel assembly 120, the cutting tool 130 and the conveying assembly 160 can be driven by a single driving body, thereby simplifying the driving structure and reducing the driving cost. Moreover, since the driving unit 150 is arranged on the lower side of the vehicle frame main body 111, the occupied volume of the driving unit 150 can be reduced, facilitating the arrangement and installation of other structures.

[0070] When transmitting and connecting the movable wheel set 112, the guide wheel assembly 120, the cutting tool 130 and the conveying assembly 160, the present embodiment adopts the method of configuring a first transmission assembly 171, a second transmission assembly 172 and a third transmission assembly 173. Among them, the first transmission assembly 171 is in transmission connection with the first output end 153 and the movable wheel set 112, the second transmission assembly 172 is in transmission connection with the second output end 154 and the cutting tool 130, and the third transmission assembly 173 is in transmission connection with the third output end 155 and the conveying assembly 160; Among them, the first transmission assembly 171, the second transmission assembly 172 and the third transmission assembly 173 are all located on the lower side of the vehicle frame main body 111, so as to reduce the occupied volume of the transmission components and facilitate the arrangement and installation of other structures.

[0071] In addition, the vegetable harvesting device 100 further includes a fourth transmission assembly 174, a fifth transmission assembly 175 and a sixth transmission assembly 176; The fourth transmission assembly 174 is in transmission connection with the fourth output end 156; Both the fifth transmission assembly 175 and the sixth transmission assembly 176 are in transmission connection with the fourth transmission assembly 174, and the fifth transmission assembly 175 and the sixth transmission assembly 176 are respectively in transmission connection with the pressing wheel 121 and the impeller 122.

[0072] It should be noted that when configuring the foregoing first transmission assembly 171, second transmission assembly 172, third transmission assembly 173, fourth transmission assembly 174, fifth transmission assembly 175 and sixth transmission assembly 176, according to their specific installation positions, one or more of the transmission connection forms of bevel gear transmission, belt transmission and gear transmission can be adopted to meet the requirements of transmission connection.

[0073] In summary, the working process of the vegetable harvesting device 100 is as follows:

[0074] Cutting stage: Turn on the drive motor 151 to start the operation. Move forward at a certain speed to harvest Chinese cabbages in a single row. The top pressing wheel 121 provides a top pressing and supporting effect when cutting the Chinese cabbages. The two dial impellers 122 rotate inward to remove the outer waste leaves of the Chinese cabbages, separate the leaves of adjacent Chinese cabbages on the left and right, and straighten the Chinese cabbages. The upper top pressing wheel 121 presses tightly on the top of the Chinese cabbages, and the disc cutter 130 directly cuts the Chinese cabbages from the upper part of the stem out of the soil.

[0075] Transport stage: After the Chinese cabbages are cut by the cutter 130, they enter the material guiding channel 115. The two dial impellers 122 push the Chinese cabbages that fall into the material guiding channel 115 backward at an appropriate angle and speed. At the same time, the top pressing wheel 121 applies appropriate pressure from the top of the Chinese cabbages to ensure that the Chinese cabbages are closely arranged during transportation and avoid scattering. Subsequently, the Chinese cabbages come into contact with the conveying assembly 160 and are conveyed backward under the action of the conveying assembly 160.

[0076] Collection stage: When the Chinese cabbages are conveyed backward under the action of the conveying assembly 160, the convex curling belt 164 on the conveyor belt 161 can play a role in pushing the Chinese cabbages, so that the Chinese cabbages are collected into the aggregate bin 140. When the aggregate bin 140 is full of Chinese cabbages, the staff can quickly take them out and replace them with a new empty bin to ensure that the collection work can be carried out continuously.

[0077] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
