Description

Technical Field

[0001] This utility model relates to the field of forestry machinery technology, specifically to a detachable soil ball packing device that can be installed on a spherical tree digger. Background Technology

[0002] In recent years, the demands for landscaping, forestry, urban construction, and nursery management have raised the requirements for agricultural equipment. Before the advent of mechanized tree diggers, tree transplantation mainly relied on manual digging, which involved using shovels, picks, and other tools. This method was inefficient, labor-intensive, and prone to damaging the root system, affecting the survival rate of the trees. With the application of hydraulic technology, digging devices that can be used with shovels have emerged. Tree diggers, as devices that can quickly excavate the root system and surrounding soil of trees, have greatly improved the efficiency of transplanting and reduced the intensity of manual labor.

[0003] However, due to soil texture, mechanical vibration, or bumps during transportation, the root ball is easily loosened or even falls off, leading to exposed roots and seriously affecting the survival rate of transplanted trees. Therefore, it is necessary to pack the soil balls immediately after digging up the trees. This packing work is often done manually or by other specialized soil ball packing equipment. Currently, soil ball packing machines are often large in size and lack mobility, making it difficult to participate in tree digging and packing operations in hilly and mountainous areas. Utility Model Content

[0004] Therefore, the purpose of this utility model embodiment is to provide a detachable soil ball packing device for tree digging machines, so as to solve the problems that soil ball packing in the current tree transplanting process relies on manual labor, and that the existing soil ball packing machines are too large and not easy to transport in hilly and mountainous areas.

The non-woven fabric unit 2 is installed on the frame 1, and a non-woven fabric roll 21 is installed on it. The moving unit 3 includes a first moving sub-unit and a second moving sub-unit, both of which are installed on the frame 1. The non-woven fabric on the non-woven fabric roll 21 passes around the first moving sub-unit and is clamped onto the second moving sub-unit. The heat-pressing unit 4 is installed between the first moving sub-unit and the second moving sub-unit. The cutting unit is fixedly installed behind the heat-pressing unit 4 and is used to cut the non-woven fabric on the non-woven fabric roll 21.

[0029] In one embodiment, the frame 1 is mainly constructed of rectangular tubes to provide strength support for the entire device. Slide rails 11 are installed on the frame 1, and the slide rails 11 are arranged in pairs and fixed to both sides of the frame 1 by bolts.

[0030] In one embodiment, a connector 12 for connecting the main arm of the tree digger 5 is installed on the frame 1; specifically, the connector 12 can be a U-shaped buckle, and the U-shaped buckle of the corresponding size can be designed according to the existing structure of the main arm of the tree digger 5.

[0031] In one embodiment, the nonwoven unit 2 includes a nonwoven fabric roll 21 and a mounting rod 22. The mounting rod 22 is mounted on the frame 1, and the nonwoven fabric roll 21 is mounted on the mounting rod 22. When subjected to force, it can rotate freely around the pivot.

[0032] In one embodiment, the first moving subunit includes a first slider 31, a first mounting bracket 32, and a first electric actuator 33. The first slider 31 is slidably disposed on the slide rail 11, the first mounting bracket 32 ​​is fixed on the first slider 31, and one end of the first electric actuator 33 is mounted on the frame 1, and the other end is mounted on the first mounting bracket 32.

[0033] In one embodiment, the second moving subunit includes a second slider 34, a second mounting frame 35, a second electric actuator 36, and a clamp 37. The second slider 34 is slidably disposed on the slide rail 11, and the second mounting frame 35 is fixed to the second slider 34. One end of the second electric actuator 36 is mounted on the frame 1, and the other end is mounted on the second mounting frame 35. The clamp 37 is mounted on the second mounting frame 35 and is used to clamp the nonwoven fabric. During operation, the nonwoven fabric is pulled and spread out flat as the second mounting frame 35 moves.

[0034] In one embodiment, the hot pressing unit 4 includes a pair of first hot pressing blocks 41, a ceramic heating element 42, and a pair of second hot pressing blocks 43. The pair of first hot pressing blocks 41 are fixed to the first movable subunit, the ceramic heating element 42 is lined within the first hot pressing blocks 41, and the pair of second hot pressing blocks 43 are fixed to the second movable subunit. The pair of first heating blocks are mounted in pairs on the first mounting bracket 32. The hot pressing surface of the first heating blocks may be provided with several protrusions 44 to increase the hot pressing effect and contact pressure of the non-woven fabric. The ceramic heating element 42 is embedded inside the first heating blocks to raise their temperature to the operating temperature.

[0035] In one embodiment, the hot pressing unit 4 further includes a support rod 45, which is mounted on the first moving subunit to support the nonwoven fabric, facilitating the unfolding and flattening effect of the nonwoven fabric after traction.

[0036] In one embodiment, the hot pressing unit 4 further includes an isolation support rod 46, which is installed on the upper and lower sides of the first hot pressing block 41 to isolate the non-woven fabric and prevent the non-woven fabric from naturally drooping and contacting the heating plate during non-pressing, thus preventing it from sticking to the heating block or melting. This ensures that the non-woven fabric only contacts the heating block during closed hot pressing.

[0037] In one embodiment, reference Figure 6 The fabric cutting unit 5 includes a cutting blade 51, a support spring 52, and a cutting track 53. The cutting track 53 is mounted on the frame 1. The support spring 52 contains a guide post. The cutting blade 51 faces upwards towards the non-woven fabric and is fixed to the support spring 52. One end of the support spring 52 is fixed to the cutting track 53, and the other end is fixedly connected to the non-blade side of the cutting blade 51. When the tree ball falls, the falling non-woven fabric collides with the cutting blade 51, and the non-woven fabric is caught on the blade of the cutting blade 51 and cut.

[0038] The working principle of this utility model is as follows: Before the tree digger 5 digs, the ceramic heating element 42 preheats the heating block to the working temperature. The first electric push rod 33 and the second electric push rod 36 are fully retracted, pulling the first mounting frame 32 and the second mounting frame 35 out of the arm of the tree digger 5. After the tree digger 5 completes the tree digging operation, it lifts the tree and the root soil block to the top of the packing device. The non-woven fabric is pulled out from the non-woven fabric roll 21 and clamped at the corners of the non-woven fabric by the clamp 37. The second electric push rod 36 extends and pushes the second mounting frame 35 to pull the non-woven fabric open. The tree digger 5 lowers the tree and soil block to a suitable height. During this process, the non-woven fabric roll 21 will be pulled to rotate freely around the non-woven fabric roll 21, and the non-woven fabric will unfold to wrap the bottom of the soil block. The first electric push rod 33 extends and the second electric push rod 36 retracts to clamp the soil block. During wrapping, the tree roots below are covered, and the non-woven fabric roll 21 continues to rotate and unfold. The first mounting bracket 32 ​​and the second mounting bracket 35 are attached to the first heating block and the second heating block, the hot pressing unit 43 is turned on, and pressure is maintained for several seconds. After the non-woven fabric is completely and firmly attached, the first electric push rod 33 retracts and the second electric push rod 36 extends, thus completing the soil clod packaging work. Then, both the first electric push rod 33 and the second electric push rod 36 retract and exit the main arm of the tree digger 5. At this time, the cloth cutting blade on the tree ball falling and cutting unit collides with the falling non-woven fabric, and the non-woven fabric is caught on the blade of the cloth cutting blade and cut. The above process is repeated to enter the next working cycle.

[0039] This utility model serves as an auxiliary packing device for a tree digger 5. It can be quickly installed on existing tree diggers 5 via the connector 12 and fixing plate, allowing for easy assembly and disassembly. As the tree digger 5 works in complex hilly and mountainous forest terrain, it easily moves and works, immediately packing tree roots and soil after the tree digging operation. The fixing frame is driven by an electric actuator to move on the guide rail, providing high control precision. The first electric actuator 33 and the second electric actuator 36 simultaneously serve as the opening and closing mechanism of the hot pressing unit 4 and the traction device for the non-woven fabric. The heating block pressing surface of the hot pressing unit 4 can be provided with several square protrusions 44 to enhance the pressing effect of the non-woven fabric. It has a built-in ceramic heating element 42 to raise the heating block to a suitable temperature. After packing, the cutting blade on the tree ball falling and cutting unit collides with the falling non-woven fabric, cutting the non-woven fabric onto the blade, completing one tree ball packing operation. This solves the problems of the inability to pack soil blocks in time during the current transplanting process, which leads to the scattering of soil blocks around tree roots and resulting in low tree survival rates, as well as the large size of existing soil block packing machines, which are inconvenient to move through complex hilly and mountainous forest areas. This improves the mechanization of forestry transplanting.
