Description

Technical Field

[0001] The invention relates to a planting and fertilizing machine device, in particular to a tree planting and fertilizing machine device used for restoration of degraded forests in the Three Norths, and belongs to the technical field of tree planting. Background Art

[0002] During the restoration process, in order to increase the growth rate and survival rate of plants, it is necessary to use a fertilizer spreader for fertilization. At present, in the process of fertilization, a self-propelled fertilizer spreader is often used to dig trenches along the direction of plant planting, and fertilizer is injected into the inside of the trench and buried. Although the utilization rate of fertilizers is improved, trenching during operation will destroy the surface crust and vegetation, aggravate wind erosion, and when trenching, a large power is required for traction. If a diesel engine is used for driving, the weight of the equipment is large and the device is easy to sink into the sand during operation. If a battery is used for power driving, the battery life is short and the practicality is low.

[0003] For this purpose, a tree planting and fertilization machine device for restoration of degraded forests in the Three Norths is designed to optimize the above problems. Summary of the invention

[0004] The main purpose of the present invention is to provide a tree planting and fertilizing machine device for the restoration of degraded forests in the Three Norths.

The extraction and insertion fertilization mode can not only accurately control the fertilization depth and spacing, so that the concentrated root area of ​​the trees can evenly absorb nutrients, but also directly inject fertilizer into the deep soil layer to reduce the loss of nutrients caused by surface evaporation and rainwater erosion. At the same time, only tiny holes are formed at the target position.

[0018] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0019] like Figure 1-Figure 8As shown, the present embodiment provides a tree planting and fertilizing machine device for restoration of degraded forests in the Three Norths, comprising a frame 1, a moving wheel 2 rotatably installed at the bottom of the frame 1, and a handle 4 located at the rear end of the frame 1, a driving motor 3 for controlling the rotation of the moving wheel 2 is installed at the bottom of the frame 1, a battery 5 is provided at the top of the frame 1, a vertical plate 6 is fixed to one side of the top of the frame 1, a fertilizer box 7 is fixed to the top of the vertical plate 6, a fixed tube 8 is vertically fixed to the side of the front end of the frame 1 away from the vertical plate 6, a plug 9 is vertically slidably arranged inside the fixed tube 8, a quick extraction mechanism 10 for controlling the insertion and extraction of the plug 9 is provided at the bottom of the fertilizer box 7, a quantitative feeding mechanism 11 is provided between the end of the fertilizer box 7 and the plug 9, and a release mechanism 12 is provided at the bottom of the plug 9.

[0020] The overall working principle is as follows: when in use, hold the handle 4 and pull the device to the side of the tree, inject fertilizer into the fertilizer box 7, the battery 5 supplies power to the drive motor 3, and then start the drive motor 3 to control the moving wheel 2 to rotate clockwise, pull the device and move it along the direction of tree planting, and during the movement of the device, use the quantitative feeding mechanism 11 to quantitatively inject fertilizer into the inside of the insert tube 9, and the bottom end of the insert tube 9 is blocked by the release mechanism 12 when it is not inserted into the ground, and the bottom end of the release mechanism 12 is higher than the ground, and then use the quick extraction mechanism 10 to insert the insert tube 9 containing fertilizer into the soil, and after it is completely inserted, the release mechanism 12 releases the blocking state of the bottom end of the insert tube 9, and the fertilizer falls into the pit, and after the fertilizer is discharged, the insert tube 9 is pulled out again, and the above steps are repeated, and fertilization is continued during the movement of the device.

[0021] In this embodiment, a driving spindle 13 is rotatably mounted on the vertical plate 6, a first sprocket mechanism 14 is provided between the driving spindle 13 and the side of the moving wheel 2, a spiral conveying rod 15 is rotatably mounted inside the fertilizer box 7 along the length direction, and a second sprocket mechanism 16 is provided between the end of the driving spindle 13 and the spiral conveying rod 15.

[0022] Local working principle: The first sprocket mechanism 14 includes two sprockets, one of which is fixed to the rotating shaft of the moving wheel 2, and the other is fixed to the driving main shaft 13. The two sprockets are connected by a chain. When the driving motor 3 drives the moving wheel 2 to rotate, the first sprocket mechanism 14 is used to control the driving main shaft 13 to rotate. The second sprocket mechanism 16 is also composed of two sprockets, one of which is fixed to the end of the driving main shaft 13, and the other is fixed to the rotating shaft of the screw conveying rod 15. Through chain transmission, the driving main shaft 13 cooperates with the second sprocket mechanism 16 to control the rotation of the screw conveying rod 15 to release the fertilizer toward the position of the quantitative feeding mechanism 11.

[0023] In this embodiment, the spiral conveying rod 15 is located at the inner bottom end of the fertilizer box 7 , and both sides of the bottom of the fertilizer box 7 are inclined toward the spiral conveying rod 15 .

[0024] Partial working principle: The setting of the bottom bevel of the fertilizer box 7 can facilitate the collection of fertilizers and avoid the residue of fertilizers.

[0025] In this embodiment, the quick extraction mechanism 10 includes a connecting rod 1001, a cross plate 1002, a first spring 1003, a first shift block 1004 and a second shift block 1005. The connecting rod 1001 is fixed at the top of the insertion tube 9. The cross plate 1002 is horizontally fixed to the top of the connecting rod 1001. The end of the cross plate 1002 is close to the top of the driving main shaft 13, and the cross plate 1002 is higher than the horizontal plane where the first spring 1003 is located. The first spring 1003 is fixed between the top of the cross plate 1002 and the bottom of the fertilizer box 7. The first shift block 1004 is fixedly installed on the driving main shaft 13. The first shift block 1004 and the cross plate 1002 are located on the same vertical plane. The length of the first shift block 1004 is equal to the straight length from the driving main shaft 13 to the connecting rod 1001.

[0026] Local working principle: when the driving main shaft 13 rotates, the clockwise rotation of the first shift block 1004 will be controlled. After the first shift block 1004 contacts the bottom of the cross plate 1002, as the first shift block 1004 continues to rotate, the cross plate 1002 will be controlled to move upward and the first spring 1003 will be compressed. When the first shift block 1004 is separated from the cross plate 1002, the rotation angle of the first shift block 1004 is less than ninety degrees. The first spring 1003 applies a downward elastic force to the cross plate 1002 to control the rapid downward movement of the insert 9. Due to inertia, the insert 9 will be inserted into the soil. After being inserted to a certain depth, the release mechanism 12 is used to release the fertilizer. Due to the pulling force of the first spring 1003, the insert 9 will quickly move upward after being inserted to the deepest point. The insertion and upward movement of the insert 9 are completed in an instant, and the device is always in a moving state at this time.

[0027] In this embodiment, the surface of the first shift block 1004 is arc-shaped, and the bottom of the horizontal plate 1002 and the end of the first shift block 1004 are coated with a wear-resistant coating, and the wear-resistant coating is a tungsten carbide wear-resistant coating with a thickness of 0.3 mm.

[0028] Partial working principle: The friction between the first shifting block 1004 and the horizontal plate 1002 is small, which increases the service life.

[0029] In this embodiment, a second shift block 1005 is fixedly installed on the driving main shaft 13, a sliding rod 1006 is horizontally slidably arranged at the top end of the side of the fixed tube 8, and the sliding rod 1006 penetrates the side wall of the fixed tube 8, a semicircular extrusion block 1007 is fixed to the outer end of the sliding rod 1006, and a second spring 1008 is arranged between the semicircular extrusion block 1007 and the side of the fixed tube 8.

[0030] Local working principle: The second block 1005 is opposite to the first block 1004, with an angle of one hundred and eighty degrees between them. The second block 1005 will rotate with the driving spindle 13. When the first block 1004 and the cross plate 1002 are released, the second block 1005 is not in contact with the semicircular extrusion block 1007. However, during the period when the insert tube 9 is squeezed into the soil by the first spring 1003 and then moves upward, the driving spindle 13 drives the second block 1005 to rotate a certain angle. After the insert tube 9 moves upward, the second block 1005 squeezes the semicircular extrusion block 1007. At this time, the end of the sliding rod 1006 contacts the side of the insert tube 9, which will increase the resistance of the insert tube 9 to move upward, reduce the elastic potential energy, and quickly reset the insert tube 9.

[0031] In this embodiment, a rubber anti-slip block is fixed to the inner end of the slide rod 1006, and the rubber anti-slip block is provided with anti-slip grooves.

[0032] Partial working principle: The use of the rubber anti-sliding block increases the friction resistance between the slide rod 1006 and the cannula 9, thereby accelerating the resetting of the cannula 9.

[0033] In this embodiment, the release mechanism 12 includes a limit block 1201, a pad 1202, a conical plate 1203, a V-shaped spring piece 1204 and a pull rope 1205. The limit block 1201 is fixed to the bottom end of the outer side of the cannula 9, the pad 1202 is vertically slidably set on the cannula 9, the bottom end of the cannula 9 is symmetrically hingedly installed with a conical plate 1203, a V-shaped spring piece 1204 is arranged between the two groups of conical plates 1203, and a pull rope 1205 is arranged between the side of the conical plate 1203 and the pad 1202.

[0034] Local working principle: After the insert tube 9 is inserted into the soil, the bottom of the pad 1202 will contact the ground, and the insert tube 9 will move down a distance, but the position of the pad 1202 will not move down. When the insert tube 9 continues to move down, the pad 1202 will pull the two groups of conical plates 1203 through the pull rope 1205. The two groups of conical plates 1203 will open outward around the hinge point, and the fertilizer inside will automatically flow out. When the insert tube 9 is pulled out of the soil, the two groups of conical plates 1203 are closed and reset under the elastic force of the V-shaped spring piece 1204.

[0035] In this embodiment, wire holes 1206 are symmetrically opened on the pad 1202, and the pull rope 1205 passes through the inside of the wire hole 1206. The sides of the pad 1202 are all threaded with positioning bolts 1207, and the ends of the positioning bolts 1207 extend into the inside of the wire hole 1206 and squeeze the pull rope 1205 to fix it.

[0036] Local working principle: By adjusting the length of the pull rope 1205, the insertion depth of the tube 9 can be controlled. If the length between the pull rope 1205 on the pad 1202 and the conical plate 1203 is short, after the tube 9 is inserted into the soil, the V-shaped spring piece 1204 will unfold more quickly, the resistance during the insertion of the tube 9 will increase, and the insertion depth will become shallower. If the pull rope 1205 is longer, the V-shaped spring piece 1204 will unfold to release the fertilizer only after the tube 9 is inserted to a certain depth.

[0037] In this embodiment, the quantitative feeding mechanism 11 includes a feeding hopper 1101, a turntable 1102, a quantitative groove 1103, a feeding pipe 1104 and a through groove 1105. The feeding hopper 1101 is fixed at the end of the fertilizer box 7 and is connected to the interior of the fertilizer box 7. The turntable 1102 is rotatably installed inside the lower hopper 1101. The side of the turntable 1102 is fixedly connected to the driving main shaft 13. The quantitative grooves 1103 are symmetrically opened on the turntable 1102. The feeding pipe 1104 is fixed to the bottom end of the feeding hopper 1101. The bottom end of the feeding pipe 1104 is installed on the side of the fixed pipe 8 and is connected to the interior of the fixed pipe 8. The insertion tube 9 is provided with a through groove 1105 which is connected to the feeding pipe 1104.

[0038] Partial working principle: During the rotation of the driving main shaft 13, the turntable 1102 will be driven to rotate. One rotation of the driving main shaft 13 will control the insert tube 9 to insert and pull out the fertilizer once, and one rotation of the turntable 1102 will perform two quantitative feedings to ensure that the amount of fertilizer applied is the same each time. The fertilizer enters the inside of the insert tube 9 through the feeding pipe 1104. In addition, during use, a block with the same shape as the quantitative groove 1103 can be inserted into the inside of the quantitative groove 1103, and the block can be penetrated by a screw to fix it in the inside of the quantitative groove 1103, and a group of quantitative grooves 1103 can be blocked. When the turntable 1102 rotates one circle, only one feeding will be performed, which can be freely adjusted according to the amount of application, and is easy to use.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
