Description
Technical Field
[0001] This utility model belongs to the technical field of equipment for floating tray seedling cultivation, specifically relating to a track-type leaf trimmer. Background Technology
[0002] Floating tray seedling raising, also known as floating seedling raising or floating planting, involves floating foam trays filled with lightweight seedling substrate on the water surface. Seeds are sown in the substrate, and seedlings take root and grow in the substrate, absorbing water and nutrients from the substrate and waterbed. This method has the advantages of uniform, strong, and consistent seedlings, saving labor and seeds, facilitating transportation, and achieving a high transplant survival rate, making it popular among farmers. During the seedling raising period, to ensure the seedlings grow stronger and continue to thrive after transplanting, the current method involves pruning the upper branches and leaves of the seedlings multiple times before transplanting using a leaf pruning machine. This ensures that nutrients are fully supplied to the lower part of the seedling, allowing it to grow sufficiently strong before transplanting.
[0003] Utility model patent CN202322462998.4 discloses a "track-type battery-powered leaf trimmer for floating tray seedling cultivation," specifically disclosing the following: The design incorporates wheels, a walking support, parallel guide rails, and rollers to enhance the ease of operation; the discharge port and straw collection bag collect the trimmed seedling branches and leaves, preventing them from scattering and affecting the environment. However, this single-sided discharge port design easily leads to untimely discharge, causing the trimmed seedling branches and leaves to accumulate and block the cover, while seedling debris falls through the cutting opening on the lower surface of the cover onto the seedling surface, impacting subsequent seedling growth. Therefore, developing a track-type leaf trimmer with a reasonable structure and good performance is essential to address these issues. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a track-type leaf trimmer with a reasonable structural design and good performance.
[0005] The purpose of this utility model is achieved as follows: A track-type leaf trimming machine includes a seedling placement base, a traveling support, and a leaf trimming mechanism. The seedling placement base is generally square, with a seedling placement groove in the center of its upper surface. Two traveling supports are symmetrically arranged on both sides of the upper end of the seedling placement base, with wheels at the front and rear ends of their lower surfaces. These wheels enable longitudinal movement along the upper end of the seedling placement base. Two parallel guide rails are jointly mounted between the two traveling supports. The leaf trimming mechanism is laterally slidable between the two guide rails and includes a leaf trimming frame and a sensor switch. The leaf trimming frame consists of an outer frame and an inner frame that can move relatively vertically, with the inner frame fitted inside the outer frame. Rollers are rotatably mounted at the four corners of the upper end of the outer frame, and the lower ends of the rollers engage with the upper surface of the guide rails to achieve sliding motion. The inner frame is connected to a top plate, which is fixedly attached to the top of the outer frame. A lifting handwheel is vertically rotatable through the center of the top plate, and a screw is vertically threaded through the center of the lifting handwheel. A connecting plate is fixedly attached to the upper end of the inner frame, and a leaf-cutting cover is fixedly attached to the lower end. The upper surface of the connecting plate is vertically fixedly connected to the lower end of the screw. The leaf-cutting cover is a hollow cylinder with a leaf-cutting motor vertically fixed at the center of its upper surface and a circular leaf-cutting opening in the middle of its lower surface. The two sides are symmetrically connected to the discharge ports. The output end of the leaf-cutting motor faces downward and is concentrically fixedly connected to a vertical shaft. The lower end of the vertical shaft passes through the upper surface of the leaf-cutting cover, is located inside the leaf-cutting cover, and is fixedly fitted with a leaf-cutting blade. A grass-collecting bag is detachably installed on the outside of the discharge port. There are two induction switches, which are symmetrically arranged on both sides of the top plate, and the traveling bracket is equipped with a baffle that matches the induction switches.
[0006] Furthermore, a battery is installed inside the leaf-cutting frame, and an opening is provided on the upper surface of the top plate at a position corresponding to the battery. A circuit breaker, a rotary switch, and a forward / reverse module are sequentially provided on the lower side.
[0007] Furthermore, the rollers at the four corners of the upper end of the outer frame are arranged in two pairs in parallel front and rear directions, and the two pairs of rollers are concentrically connected by a coupling.
[0008] Furthermore, gear a is fixedly mounted on the outside of the coupling shaft, and a reciprocating motor is installed between the upper end of the outer frame and the lower surface of the top plate. The output end of the reciprocating motor is connected to gear b, and gear b meshes with gear a.
[0009] Furthermore, a movable auxiliary handle is vertically fixed to the side end of the upper surface of the top plate.
[0010] Furthermore, the leaf-cutting blade is integrally connected by a central connecting part and rotary cutting parts symmetrically arranged on both sides of the central connecting part. The central connecting part has a through hole at its center and is fixedly sleeved with a vertical shaft through the through hole. An inclined guide part is fixedly connected to the outer side of the rotary cutting part at the end away from the central connecting part.
[0011] The beneficial effects of this utility model are as follows: The seedling placement base and seedling placement trough facilitate the positioning of seedlings to be cut; the walking support and wheels allow for vertical adjustment of the walking support, guide rail, and leaf-cutting mechanism above the seedling placement base via external force; the leaf-cutting frame allows for vertical movement of the leaf-cutting cover and leaf-cutting blade by the relative vertical movement between the outer and inner frames, thereby enabling adjustable seedling cutting height.
[0012] This invention features discharge ports on both sides of the leaf-cutting cover, with detachable grass-collecting bags installed on the outer side of the discharge ports. Compared to existing leaf-cutting machines with a single discharge port, this structure effectively solves the problems of untimely discharge causing the accumulation and blockage of cut seedling branches and leaves inside the leaf-cutting cover, and the falling of seedling debris from the leaf-cutting opening on the lower surface of the leaf-cutting cover onto the seedling surface, which affects the subsequent growth and cultivation of the seedlings. Furthermore, the two grass-collecting bags reduce the frequency of downtime for operators due to grass-collecting bag replacement compared to a single bag. In summary, this invention has the advantages of reasonable structural design and good performance. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, a track-type leaf trimming machine includes a seedling placement base 1, a traveling support 2, and a leaf trimming mechanism 3. The seedling placement base 1 is generally square, with a seedling placement trough 11 in the center of its upper surface. There are two traveling supports 2, symmetrically arranged on both sides of the upper end of the seedling placement base 1. The front and rear ends of the lower surface of each support are equipped with traveling wheels 21, which enable longitudinal movement of the support above the seedling placement base 1. The upper ends of the two traveling supports 2 are connected by a common support structure. There are two parallel guide rails 4; the leaf-cutting mechanism 3 is laterally slidably disposed between the two guide rails 4, and includes a leaf-cutting frame 31 and an inductive switch 32. The leaf-cutting frame 31 is composed of an outer frame 311 and an inner frame 312 that can move relatively vertically, and the inner frame 312 is sleeved inside the outer frame 311. Rollers 34 are rotatably provided at the four corners of the upper end of the outer frame 311, and the rollers 34 are slidably connected to the guide rails 4 through the cooperation of the lower end of the rollers 34 with the upper surface of the guide rails 4. A top plate 33 is fixedly connected to the top of the frame 311. A lifting handwheel 37 is vertically rotatably inserted through the center of the top plate 33. A screw 36 is vertically threaded through the center of the lifting handwheel 37. A connecting plate 35 is fixedly connected to the upper end of the inner frame 312, and a leaf-cutting cover 5 is fixedly connected to the lower end. The upper surface of the connecting plate 35 is vertically fixedly connected to the lower end of the screw 36. The leaf-cutting cover 5 is a hollow cylinder. A leaf-cutting motor 6 is vertically fixed at the center of its upper surface, and the lower surface... A circular leaf-cutting opening is provided in the middle position, and the two sides are symmetrically connected to the discharge port 7. The output end of the leaf-cutting motor 6 faces downward and is concentrically fixedly connected to the vertical shaft 61. The lower end of the vertical shaft 61 passes through the upper surface of the leaf-cutting cover 5, is located inside the leaf-cutting cover 5, and is fixedly sleeved with the leaf-cutting blade 51. A grass collection bag 8 is detachably installed on the outside of the discharge port 7. There are two induction switches 32, which are symmetrically arranged on both sides of the top plate 33, and the walking bracket 2 is provided with a baffle that matches the induction switch 32.
[0024] The rollers 34 at the four corners of the upper end of the outer frame 311 are arranged in two pairs in a front-to-back direction, and the two pairs of rollers 34 are concentrically connected by a coupling 341. A gear a is fixedly mounted on the outside of the coupling 341. A reciprocating motor 39 is installed between the upper end of the outer frame 311 and the lower surface of the top plate 33. The output end of the reciprocating motor 39 is connected to a gear b, and gear b meshes with gear a. Using this structure, during use, the rotation of the reciprocating motor 39, in conjunction with the meshing of gear b and gear a, drives the coupling 341 to rotate, thereby transmitting power through the coupling 341. The rotation of 1 causes the rollers 34, which are concentrically fixed at both ends, to rotate. Thus, by rotating the rollers 34, the entire leaf-cutting mechanism 3 can move horizontally along the guide rail 4. The leaf-cutting frame 31 is equipped with a battery 38 inside. The upper surface of the top plate 33 has an opening corresponding to the position of the battery 38. A circuit breaker, a rotary switch, and a forward / reverse module are arranged sequentially on the lower side. With this structure, the opening can increase the convenience of replacing the battery 38, and the forward / reverse module can facilitate the control of the forward and reverse rotation of the reciprocating motor 39.
[0025] A movable auxiliary handle 9 is vertically fixed to the side end of the upper surface of the top plate 33. The movable auxiliary handle 9 can increase the convenience of the longitudinal movement of the walking support 2, guide rail 4 and leaf cutting mechanism 3 above the seedling placement base 1. The leaf cutting blade 51 is integrally connected by a middle connecting part and rotary cutting parts symmetrically arranged on both sides of the middle connecting part. The middle connecting part has a through hole at its center and is fixedly sleeved with the vertical shaft 61 through the through hole. An inclined guide part is fixedly connected to the outer side of the rotary cutting part away from the middle connecting part.
[0026] In use, the seedlings to be cut are first placed in the seedling placement groove 11 on the upper surface of the seedling placement base 1 through a foam tray. Then, according to the required cutting height, the height of the leaf-cutting cover 5 and the leaf-cutting blade 51 are adjusted. The specific adjustment operation is as follows: by rotating the lifting handwheel 37, the rotational connection between the lifting handwheel 37 and the top plate 33, the threaded rotational connection between the screw 36 and the lifting handwheel 37, the fixed connection between the lower end of the screw 36 and the connecting plate 35, the fixed connection between the connecting plate 35 and the inner frame 312, and the relative vertical sliding connection between the inner frame 312 and the outer frame 311 are utilized to allow the lifting handwheel 37 to rotate simultaneously. The screw 36 drives the connecting plate 35 and the inner frame 312 to move vertically. This movement of the inner frame 312, in turn, adjusts the vertical position of the leaf-cutting cover 5 fixedly connected below it, thus adjusting the height of the leaf-cutting cover 5 and the leaf-cutting blade 51. Then, under external force, the traveling wheels 21 and the auxiliary handle 9 adjust the longitudinal position of the traveling bracket 2, guide rail 4, and leaf-cutting mechanism 3 above the seedling placement base 1, moving the leaf-cutting opening below the leaf-cutting cover 5 above the seedling to be cut. Finally, the circuit breaker is turned on to power the entire device via the battery 38, and the button switch is pressed, causing the reciprocating motor 39 and the leaf-cutting motor 6 to start working simultaneously. The rotation of machine 39 drives gear b to rotate, and through the meshing of gear b and gear a, it drives shaft 341 and rollers 34 concentrically arranged at both ends of shaft 341 to rotate. Thus, the rotation of rollers 34 enables the leaf-cutting mechanism 3 to move horizontally along guide rail 4. During this horizontal movement, the rotation of leaf-cutting motor 6 drives vertical shaft 61 and leaf-cutting blade 51 to rotate, thereby enabling the leaf-cutting blade 51 to cut the seedlings in seedling placement trough 11. Simultaneously, the cooperation of induction switch 32 and baffle, along with the forward and reverse rotation module, enables the leaf-cutting mechanism 3 to reciprocate horizontally along guide rail 4. Furthermore, this utility model, by providing discharge ports 7 on both sides of the leaf-cutting cover 5, and detachably installing grass collection bags 8 on the outer side of the discharge ports 7, effectively solves the problems of seedling branches and leaves accumulating and blocking inside the leaf-cutting cover 5 due to untimely discharge, and seedling branch and leaf debris falling onto the seedling surface through the leaf-cutting opening on the lower surface of the leaf-cutting cover 5, affecting the subsequent growth and cultivation of the seedlings, compared to the existing leaf-cutting machine with a single discharge port 7. At the same time, by using two grass collection bags 8, the frequency of machine downtime due to grass collection bag replacement can be reduced compared to one grass collection bag 8. In summary, this utility model has the advantages of reasonable structural design and good performance.
