Each of the two support beams 2011 has a sliding hole 2012, and the sliding hole 2012 is located between two adjacent waste leaf rotating rollers 202. The length of the sliding hole 2012 extends along the lifting direction of the lifting roller 203, and the number of sliding holes 2012 on each support beam 2011 is the same as the number of lifting rollers 203. Both ends of the lifting roller 203 are provided with extension shafts 206 that slide with the sliding holes 2012.

The other end of the lifting rod 207 passes through a guide hole and is connected to an extension shaft 206 on one side of the lifting roller 203. When the first lifting motor 209 is started, the crank-rocker mechanism drives the lifting roller 203 to move up and down along the sliding hole 2012 via the lifting rod 207.

[0021] In this embodiment, the cabbage root and leaf cleaning mechanism further includes a pressing mechanism 300. The pressing mechanism 300 includes a support frame 301, a lifting frame 302, a rack 303, a second lifting motor 304, a gear 305, and a pressing belt 306. The support frame 301 is mounted on the cabbage sorting machine frame 201. The lifting frame 302 is slidably connected to the support frame 301. A rack 303 is mounted on the lifting frame 302 along its lifting direction. The second lifting motor 304 is mounted on the support frame 301. The output shaft of the second lifting motor 304 is connected to the gear 305. The gear 305 meshes with the rack 303. The pressing belt 306 is located at the bottom of the lifting frame 302 and above the waste leaf rotating roller 202. Specifically, the support frame 301 includes two support rod groups and two connecting rods 3011 spaced apart along the width direction of the cabbage sorting machine frame 201. The two connecting rods 3011 are connected between the two support rod groups. Each support rod group includes two vertical rods 3012 and one horizontal rod 3013. The two vertical rods 3012 are spaced apart along the length direction of the cabbage sorting machine frame 201 and fixedly connected to the cabbage sorting machine frame 201. The vertical rods 3012 are provided with guide rails 307 along the lifting direction of the lifting frame 302. The lifting frame 302 is provided with sliders 308 with grooves. The guide rails 307 are slidably connected in the grooves. The horizontal rods 3013 are connected between the two vertical rods 3012 and are spaced apart above the cabbage sorting machine frame 201. The two ends of the horizontal rods 3013 are respectively provided with second lifting motors 304. Figure 1 As shown, the lifting frame 302 in this embodiment includes four movable rods 3021, which are arranged in a rectangular shape and are slidably connected to four vertical rods 3012 in a one-to-one correspondence. Each movable rod 3021 is provided with a rack 303; four second lifting motors 304, two of which are provided on each horizontal rod 3013, and each second lifting motor 304 is driven by a gear 305. Simultaneously, four second lifting motors 304 are activated, gears 305 rotate and mesh with racks 303, causing racks 303 to move vertically, thereby driving the pressure belt 306 to rise and fall vertically. Before leaf removal, the pressure belt 306 is raised and positioned at intervals above the cabbages. When the identification device 204 detects that all the cabbages in the waste leaf sorting station 205 are in place, the second lifting motors 304 are activated, causing the pressure belt 306 to move downwards until it contacts the cabbages. During leaf removal, the pressure belt 306 increases friction by ensuring better contact between the cabbages and the waste leaf rotating roller 202, thus improving leaf removal efficiency. After leaf removal is completed, the lifting roller 203 raises the cabbages while the pressure belt 306 rises to a designated position and remains in contact with the cabbages to prevent them from deviating during transport, thereby improving transport efficiency. The pressure belt 306 is made of rubber.

[0022] In this embodiment, the cabbage root and leaf trimming mechanism further includes a waste conveyor belt 400 and a guide plate 401. The waste conveyor belt 400 is spaced apart below the cabbage conveying device 101, the waste leaf rotating roller 202, and the lifting roller 203. The guide plate 401 is located between the root-cutting saw blade 102 and the waste conveyor belt 400. Specifically, the guide plate 401 is inclined downwards, with its upper end below the root-cutting saw blade 102 and its lower end above the waste conveyor belt 400. The waste conveyor belt 400 is mounted on the third frame 402 and includes a conveyor belt that is sleeved around the drive roller and the driven roller. The drive roller is connected to the fourth drive motor 403. During the processing of Chinese cabbage, the cut roots fall onto the guide plate 401 and slide down to the waste conveyor belt 400, while the peeled leaves fall directly onto the waste conveyor belt 400, thus realizing the collection and transfer of waste, which is conducive to the unified treatment of waste in the future.

[0023] In this embodiment, the waste leaf rotating roller 202 is provided with spirally wound protrusions 2022. Through the above-mentioned arrangement, the contact area between the roller and the Chinese cabbage is increased. When the roller rotates to remove the leaves, the pulling force generated by the spiral structure helps to tear the leaves from the cabbage stem, thereby improving the leaf removal effect and efficiency. In addition, the spiral structure helps to guide the Chinese cabbage to move or rotate in a predetermined direction.

[0024] The principle of the cabbage root-cutting and leaf-cleaning mechanism provided by this utility model is as follows: In operation, the first drive motor 1011 and the second drive motor 104 are started. The cabbage to be cut is placed into the feed end of the conveyor belt, causing it to move towards the discharge end. The root-cutting saw blade 102 rotates in the opposite direction to the cabbage. When the cabbage reaches the root-cutting saw blade 102, the blade cuts off the root of the cabbage by rotating. The cut root slides down the guide plate 401 onto the waste conveyor belt 400, which removes the waste. The cut-off root continues to move until it falls onto the waste leaf rotating roller 202 at the feed end of the cabbage sorting frame 201. At this point, each waste leaf rotating roller 202 rotates towards the discharge end of the cabbage sorting frame 201, causing the cabbage to move towards the discharge end. When the photoelectric sensor detects that all the cabbages at the waste leaf sorting station 205 are in place, the cabbage conveyor... Device 101 and root cutting saw blade 102 stop operating; the second lifting motor 304 is started, causing the pressure belt 306 to move downwards until it contacts the Chinese cabbage. At the same time, the first lifting motor 209 is started, causing the lifting roller 203 to descend to a position lower than the waste leaf rotating roller 202. When the lifting roller 203 reaches the preset position, the two adjacent waste leaf rotating rollers 202 rotate towards or away from each other to remove leaves. During the leaf removal process, the damaged leaves that detach from the Chinese cabbage fall onto the waste conveyor belt 400, which transports the waste away from the site. When the waste leaf rotating roller 202 stops rotating after running for a preset time, the lifting roller 203 rises to a position level with the waste leaf rotating roller 202. At the same time, the pressure belt 306 moves upwards to a designated position. When the waste leaf rotating roller 202 reaches the preset position, it rotates towards the discharge end of the Chinese cabbage sorting frame 201 to transport the de-leaved Chinese cabbage to the next process. Example 2

[0025] Please see Figures 3 to 4As shown, the following describes a cabbage root and leaf trimming mechanism provided in Embodiment 2 of this utility model. The difference between this embodiment and Embodiment 1 is only that: lifting rods 207 are connected below the extension shafts 206 at both ends of each lifting roller 203, and a lifting beam 215 is connected below the lifting rods 207 on the same side of each lifting roller 203; the lifting drive device includes a slide 216, a lifting screw 217, and a first lifting motor 209. The slide 216 is mounted on the lifting beam 215 and threadedly connected to the lifting screw 217. The lifting screw 217 is mounted on the cabbage sorting frame 201. The first lifting motor 209 is driven by the lifting screw 217, driving the lifting screw 217 to rotate, causing the slide 216 to move up and down along the lifting screw 217, thereby driving the lifting beam 215 to rise and fall. The number of first lifting motors 209 and lifting screws 217 can be multiple. The first lifting motors 209 and lifting screws 217 are connected in a one-to-one correspondence. For example, two first lifting motors 209 are provided below each lifting beam 215, and each first lifting motor 209 is driven and connected to one lifting screw 217.

[0026] In this embodiment, a first mounting beam 218 and a second mounting beam 219 are sequentially arranged below each support beam 2011. The first mounting beam 218 and the second mounting beam 219 are arranged at intervals and are respectively connected between two support leg assemblies. The lifting beam 215 is located between the support beam 2011 and the first mounting beam 218. One end of the lifting screw 217 is mounted on the support beam 2011 through the first fixing seat 220, and the other end of the lifting screw 217 is mounted on the first mounting beam 218 through the second fixing seat 221. The first lifting motor 209 is mounted on the second mounting beam 219, and the output end of the first lifting motor 209 is connected to the lifting screw 217 through the coupling 223.
