Description

Technical Field

[0001] The invention relates to the technical field of forest tree breeding, in particular to a multi-purpose forestry fruit tree seedling transplanting device. Background Art

[0002] When transplanting fruit tree seedlings, a transplanter is usually used.

The guide groove 202 of the present invention; an adjusting arm assembly 3, the adjusting arm assembly 3 includes a fixed die set 301, a movable die set 302, an axle frame 303 and a limiting rod 304, the fixed die set 301 is fixedly assembled on the connecting hole 203, a movable die set 302 is also provided on one side of the fixed die set 301, a plurality of limiting rods 304 are arranged in an array on the movable die set 302, the limiting rods 304 are limitedly slidably inserted on the fixed die set 301, and an axle frame 303 is also provided on the bottom side of the movable die set 302; an excavating knife assembly 4, the excavating knife assembly 4 includes a knife frame 401, a positioning shaft 402, a guide rail 403, a slide 404, an excavating knife assembly 4 The tool holder 401 includes a tool 405, a hydraulic cylinder 406 and a pin joint 407. A positioning shaft 402 is provided at the bottom of the tool holder 401. The positioning shaft 402 is rotatably assembled in the shaft frame 303. A guide rail 403 is also provided on the outer wall surface of the tool holder 401 away from the C-shaped frame 201. One end of the slide 404 is slidably assembled on the guide rail 403. The other end of the slide 404 is fixedly assembled with an excavating tool 405. One end of the hydraulic cylinder 406 is rotatably assembled on the top of the tool holder 401. A pin joint 407 is assembled on the movable shaft at the other end of the hydraulic cylinder 406. The pin joint 407 is rotatably assembled on one side of the excavating tool 405.

[0031] In actual application of this embodiment, when the device is used to transplant forestry fruit tree seedlings, the main frame 101 is used to connect the lifting equipment for transporting fruit tree seedlings, and the main frame 101 is limited to move only in the xoy plane and the third direction z. The lifting disc frame 104 is slidably assembled on the main rod 102 and meshed with the main screw rod 103, so that the main screw rod 103 can mesh and drive the lifting disc frame 104 to move along the third direction z when rotating (the main screw rod 103 is independently driven by an external driving source, which is not specifically limited here). The lateral bracket 110 at one end of the lifting disc frame 104 The two groups of C-shaped frames 201 are rotatably connected to the C-shaped frames 201, so that when the lifting disk frame 104 moves along the third direction z, the two groups of C-shaped frames 201 move synchronously with the lifting disk frame 104. Since the two groups of C-shaped frames 201 are arranged in a mirror image, the two groups of C-shaped frames 201 can be opened and closed in a clamping claw shape during the rotation process, and can clamp the fruit tree seedlings to be transplanted from the horizontal direction. When the two groups of C-shaped frames 201 are in a closed clamping state, the T-shaped bars 204 slidably assembled on the two groups of C-shaped frames 201 are both attached to the two sides of the trunk along the second direction y, so that the spacing between the two groups of T-shaped bars 204 matches the diameter of the trunk. 1 is hoisted along the third direction z with a plurality of fixed die sets 301, a plurality of limit rods 304 arranged on the movable die set 302 are all slidably assembled on the fixed die set 301, and a positioning shaft 402 is also assembled on the shaft frame 303 at the bottom side of the movable die set 302, so that the tool holder 401 and the movable die set 302 are rotatably connected. When the two groups of T-shaped rods 204 slide relative to each other according to the trunk diameter, the spacing between the fixed die set 301 and the movable die set 302 on the C-shaped frame 201 and the inclination angle between the tool holder 401 and the movable die set 302 can be adjusted. When the trunk diameter of the fruit tree seedlings to be transplanted is large, the fruit tree The main root system of the seedling is also relatively large. Since the spacing between the two groups of T-shaped rods 204 is relatively long, the sliding of the T-shaped rods 204 can control the spacing between the fixed mold group 301 and the movable mold group 302 to increase, so that the digging knife 405 on one side of the knife holder 401 moves away from the center of the tree trunk. At the same time, the positioning shaft 402 can be controlled to rotate relative to the knife holder 401, so that the positioning shaft 402 continuously moves away from the side of the knife holder 401, thereby reducing the angle between the digging knife 405 and the ground, so that when the digging knife 405 is inserted into the soil, the root system of the tree can be kept intact, and the amount of soil carried can be reduced, thereby reducing the quality of the fruit tree seedlings. The device can not only automatically position the fruit tree seedlings, eliminating the process of manual adjustment, but also automatically adjust the cutting position and cutting angle of the digging knife 405 according to the diameter of the fruit tree seedlings, ensuring the integrity of the tree root system during transplantation and improving the survival rate of the seedlings.

[0032] Furthermore, the guide rail 403 is arranged on the outer wall side of the tool holder 401 and the guide rail 403 is a curved rail, so that when the hydraulic cylinder 406 moves in a hydraulic state, the movable shaft at one end of the hydraulic cylinder 406 pushes the curved digging knife 405 to slide along this curved track through the pin joint 407, and the blade head of the digging knife 405 is rotated and inserted into the soil, thereby retaining the spherical root system of the tree.

[0033] Furthermore, several excavating knives 405 are inserted into the soil in sequence, so that during the insertion of a single excavating knives 405, the remaining several excavating knives 405 and the lifting equipment can act as counterweights and apply reverse thrust, thereby preventing the excavating knives 405 from encountering excessive resistance when being inserted into the soil at the same time, resulting in the excavating knives 405 being unable to be inserted to the preset depth.

[0034] See also Figure 3 In a preferred embodiment of the present invention, the base frame assembly 1 also includes a tail bracket 105, a push-pull seat 106, a push-pull arm 107, a secondary screw rod 108 and a push-pull driver 109, the tail bracket 105 is fixedly arranged at one end of the lifting disc frame 104, and a push-pull seat 106 is slidably arranged in the tail bracket 105 along the first direction x, and push-pull arms 107 are arranged at both ends of the push-pull seat 106, one end of the push-pull arm 107 is rotatably connected to the push-pull seat 106, and the other end of the push-pull arm 107 is rotatably connected to the C-frame 201, the secondary screw rod 108 is fixedly assembled on the tail bracket 105 and meshed with the push-pull seat 106, and the push-pull driver 109 is fixedly arranged on one side of the tail bracket 105, and the movable shaft of the push-pull driver 109 is transmission-connected to the secondary screw rod 108.

[0035] In actual application of this embodiment, the tail bracket 105 is fixedly assembled on one side of the lifting plate frame 104, and moves with the lifting plate frame 104 in the third direction z, the push-pull seat 106 is elastically slidably assembled in the tail bracket 105 along the first direction x, and both ends of the push-pull seat 106 are rotatably assembled with push-pull arms 107, and the ends of the push-pull arms 107 are rotatably assembled on one side of the C-frame 201, so that when the push-pull seat 106 moves in the first direction x, the C-frame 201 rotates around the fixed axis in the xoy plane under the traction of the push-pull arm 107, and the rotation of the two groups of C-frames 201 is controlled by the push-pull seat 106 at the same time, thereby realizing the mirror movement of the two groups of C-frames 201. Guide grooves 202 are provided at both ends of the C-frame 201, and both ends of the T-bar 204 are elastically limited and slidably assembled in the guide grooves 202. Therefore, when the two groups of C-frames 201 are mirror-imaged and close to each other, the two groups of T-bars 204 are simultaneously in contact with the tree trunk. When the two groups of C-frames 201 are in a mirror-image closed state, the elastic force exerted on the two groups of T-bars 204 can push the tree trunk to the middle of the two groups of C-frames 201, so that the multiple fixed mold groups 301 hoisted on the C-frame 201 are all facing one side of the tree trunk, so that the multiple digging knives 405 can be arranged around the tree trunk, so that the multiple digging knives 405 can apply force evenly after being inserted into the soil, thereby stably pulling the fruit tree seedlings out of the soil.

[0036] Furthermore, the push-pull driver 109 is fixedly mounted on the tail bracket 105, the auxiliary screw rod 108 is fixedly mounted on the tail bracket 105 and is meshed with the push-pull seat 106, and the movable shaft at one end of the push-pull driver 109 is transmission-connected with the auxiliary screw rod 108, so that the push-pull driver 109 drives the auxiliary screw rod 108 to rotate in the driving state, and drives the push-pull seat 106 to slide in the first direction x through the rotational engagement of the auxiliary screw rod 108, thereby adjusting the opening and closing angles of the two sets of C-shaped frames 201.

[0037] See also Figure 4 In a preferred embodiment of the present embodiment, the arm assembly 2 further includes an inclined pressure plate 205, a limiting seat 206, a sliding rod 207 and an inclined pressure rod 208. The inclined pressure plate 205 is fixedly assembled on the T-bar 204 and is spaced apart from the C-frame 201. The two groups of limiting seats 206 are respectively fixedly assembled on the two groups of C-frames 201, and the two groups of limiting seats 206 are centrally symmetrically arranged. A sliding rod 207 is slidably inserted in the limiting seat 206, and a diagonal pressure rod 208 is obliquely arranged at one end of the sliding rod 207.

[0038] In actual application of this embodiment, the inclined pressure plate 205 is fixedly assembled on the T-bar 204 and is staggered with the C-frame 201, so that when the T-bar 204 slides in the C-frame 201, the inclined pressure plate 205 does not interfere with the C-frame 201. Two groups of limit seats 206 are respectively arranged at one end of the two groups of C-frames 201, with the trunk to be clamped as the center of the circle, and the two groups of limit seats 206 are centrally symmetrically arranged, and a sliding rod 207 is elastically slidably inserted in the limit seat 206, and a diagonal pressure rod 208 is obliquely arranged at the end of the sliding rod 207. When the two groups of C-frames 201 are rotated and closed, the When the T-shaped rod 204 abuts against the tree trunk, the oblique pressure rod 208 on one side of the slide rod 207 abuts against the tree trunk at the same time, and as the C-shaped frame 201 rotates continuously, while the oblique pressure rod 208 slides on the surface of the tree trunk, the slide rod 207 is squeezed by one side of the oblique pressure rod 208 and slides in the limit seat 206 until the two groups of C-shaped frames 201 are completely closed. Through the elastic force exerted on the two groups of slide rods 207 and the elastic force exerted on the two groups of T-shaped rods 204, when the tree trunk is in an immovable state, the two groups of C-shaped frames 201 are moved and aligned to the center position of the tree trunk under the push of the reaction force.

[0039] See also Figure 7 In a preferred embodiment of the present invention, the adjusting arm assembly 3 also includes a side shaft seat 305, an adjusting rod 306, a bottom shaft seat 307, a first linkage rod 308 and a second linkage rod 309. The side shaft seat 305 is fixedly assembled on one side of the movable mold group 302, and the adjusting rod 306 is slidably inserted in the side shaft seat 305. The bottom of the adjusting rod 306 is fixedly connected to the bottom shaft seat 307, and the first linkage rod 308 and the second linkage rod 309 are rotatably assembled on the bottom shaft seat 307. The first linkage rod 308 and the second linkage rod 309 are respectively movably connected to the fixed mold group 301 and the tool holder 401.

[0040] In actual application of this embodiment, the side shaft seat 305 is fixedly arranged on one side of the movable die set 302, the adjustment rod 306 is slidably inserted in the side shaft seat 305, and the end of the adjustment rod 306 is fixedly arranged with a bottom shaft seat 307. Since the end of the first linkage rod 308 is fixedly assembled on the fixed die set 301, when the adjustment rod 306 moves in the negative direction of the third direction z, the fixed die set 301 moves in the direction away from the movable die set 302 under the pushing action of the first linkage rod 308. Since the limiting rod 304 is slidably inserted on the fixed die set 301, the distance between the fixed die set 301 and the movable die set 302 can be continuously increased. At the same time, due to the active connection between the second linkage rod 309 and the tool holder 401, when the adjustment rod 306 moves along the negative direction of the third direction z, the tool holder 401 rotates toward the side deviating from the movable die set 302 under the push of the second linkage rod 309 to adjust the inclination angle between the movable die set 302 and the tool holder 401.

[0041] Furthermore, the arm adjustment assembly 3 also includes a third linkage rod 310 and a double-headed screw rod 311, one end of the third linkage rod 310 is coaxially arranged with the second linkage rod 309, and the other end of the third linkage rod 310 is rotatably connected to the tool holder 401, and the two ends of the double-headed screw rod 311 are respectively meshed and connected with the second linkage rod 309 and the third linkage rod 310. Therefore, by driving the double-headed screw rod 311 to rotate, the meshing depth of the double-headed screw rod 311 on the second linkage rod 309 and the third linkage rod 310 can be adjusted, thereby adjusting the straight-line distance between the second linkage rod 309 and the third linkage rod 310, and then adjusting the length of the force arm between the second linkage rod 309 and the tool holder 401, so that the initial angle between the tool holder 401 and the movable module 302 can be manually adjusted.
