Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a soil loosening and fertilizing device for saline-alkali land used for garden plants. Background Art

[0002] The formation of alkaline soil and alkaline soil in my country is mostly related to the accumulation of carbonates in the soil. Therefore, the alkalinity is generally high, and plants can hardly survive in areas with severe saline-alkali soil. Saline-alkali land refers to land with high salt and alkaline content in the soil, which is usually not suitable for plant growth. Landscaping is an indispensable part of urban construction.

[0003] At present, when planting green plants on saline-alkali land, it is necessary to loosen the soil before burying seeds and applying fertilizers. Different plants have different optimal planting densities, and thus the soil area required for a single plant is also different. However, the existing soil loosening and fertilizing devices cannot change the planting distance between two adjacent seeds. Different plants need to replace different devices, which increases the cost.

[0004] To this end, we provide a soil loosening and fertilizing device for garden plants in saline-alkali land to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a soil loosening and fertilizing device for garden plants in saline-alkali land. By making a part of the blocking blocks fit with the inner wall of the material receiving hole on the turntable, the blocking blocks are used to separate the feed pipe and the material receiving trough, so that in the remaining material receiving trough that can receive seeds or fertilizers, the distance between two adjacent material receiving troughs for conveying seeds becomes larger, and the planting density of the corresponding plants becomes smaller. Then, plants with different optimal planting densities can be adapted through one device, which saves costs and solves the problem that the existing soil loosening and fertilizing device cannot change the planting distance between two adjacent seeds, and different plants need to replace different devices, which increases costs.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] For specific embodiment 1, please refer to Figure 1-7 The present invention is a soil loosening and fertilizing device for saline-alkali land of garden plants, comprising a fertilizer vehicle 1; a storage barrel 2 is arranged on the fertilizer vehicle 1; two material discharge assemblies 3 are symmetrically arranged on the bottom surface of the storage barrel 2; the material discharge assembly 3 comprises a material discharge pipe 4 which is fixed through the inner bottom surface of the storage barrel 2; a hollow circular plate 5 is fixed at the bottom end of the material discharge pipe 4; a turntable 6 is rotatably arranged on the inner wall of the hollow circular plate 5; an operating groove 7 which is connected with the inside of the hollow circular plate 5 is opened on the side surface of the hollow circular plate 5; a plurality of material receiving grooves 8 are evenly distributed in a circular array inside the turntable 6; an installation groove 9 is opened inside the turntable 6; material receiving holes 10 are symmetrically opened on the inner wall of the material receiving groove 8; the two material receiving holes 10 respectively penetrate the side surface of the turntable 6 and the inner wall of the installation groove 9; a blocking block 11 is slidably arranged on the inner wall of the material receiving hole 10.

[0029] The operation process of this embodiment is as follows: a fertilizer pipe is fixed through the side surface of the hollow circular plate 5, with the bottom end of the fertilizer pipe facing downward. Taking the highest planting density of plants as an example, the blocking block 11 is first pushed so that the blocking block 11 fits with the inner wall of the material receiving hole 10 close to the inner wall of the installation groove 9, and then the other material receiving hole 10 in the corresponding material receiving groove 8 is opened, and the seeds and fertilizers are placed into the storage barrel 2.

[0030] Push the fertilizer spreading vehicle 1 and rotate the turntable 6 at the same time. When the receiving hole 10 on the turntable 6 is aligned with the feeding tube 4, the seeds or fertilizers fall into the receiving trough 8. When the receiving hole 10 is misaligned with the feeding tube 4, the seeds or fertilizers remain in the feeding tube 4 and remain motionless. When the turntable 6 continues to rotate to drive the receiving hole 10 to be aligned with the fertilizer tube, the seeds or fertilizers fall from the fertilizer tube to the soil, thereby realizing automatic feeding of seeds and fertilizers.

[0031] When it is necessary to plant other plants, the planting density becomes smaller, and some blocking blocks 11 are selected accordingly, and these blocking blocks 11 are pushed to fit the inner wall of the receiving hole 10 on the turntable 6, so that the corresponding receiving trough 8 cannot receive the seeds or fertilizers dropped from the lower feeding pipe 4. When the blocked receiving hole 10 is aligned with the lower feeding pipe 4, the blocking block 11 will separate the lower feeding pipe 4 and the receiving trough 8, so that in the remaining receiving trough 8 that can receive seeds or fertilizers, the distance between the two adjacent receiving troughs 8 for conveying seeds becomes larger, and the planting density of the corresponding plants becomes smaller, and then one device is used to adapt to plants with different optimal planting densities, saving costs.

[0032] For specific embodiment 2, please refer to Figure 1-7 On the basis of the first specific embodiment, the fertilizer spreading vehicle 1 comprises two parallel fixed shafts 12; circular rings 13 are fixed at both ends of the fixed shaft 12; a Y-shaped shaft 14 is fixed between the two opposite circular rings 13; a slotted block 15 is fixed at the end of the Y-shaped shaft 14; and connecting shafts 16 are fixed on the side surfaces of the other two opposite circular rings 13.

[0033] Specifically, a U-shaped shaft 17 is fixed between the top ends of the two connecting shafts 16; the storage bucket 2 is fixed between the two ends of the U-shaped shaft 17; an inclined shaft 18 is fixed on the side surface of the U-shaped shaft 17; a horizontal shaft 19 is fixed on the top end of the inclined shaft 18; a rotating shaft 20 is rotatably arranged between the inner walls of the two circular rings 13; rollers 21 are symmetrically fixed at both ends of the rotating shaft 20.

[0034] Furthermore, a partition plate 22 is fixed to the inner wall of the storage barrel 2; a cover 23 is provided on the surface of the storage barrel 2; an inner ring 24 and a plug-in plate 25 are fixed to the inner top surface of the cover 23; the side surface of the inner ring 24 is in contact with the inner wall of the storage barrel 2; and a plug-in groove 26 is provided on the surface of the partition plate 22 for plugging with the plug-in plate 25.

[0035] The operation process of this embodiment is as follows: the partition plate 22 divides the interior of the storage barrel 2 into two cavities, the discharge pipes 4 of the two discharge components 3 are respectively connected to the two cavities, the seeds and fertilizers are respectively placed in the two cavities, and then the cover 23 is covered so that the plug-in plate 25 is plugged into the plug-in groove 26, and at the same time the inner ring 24 fits the inner wall of the storage barrel 2 to prevent the seeds and fertilizers from mixing during the pushing process of the fertilizer spreading vehicle 1.

[0036] Then, the horizontal axis 19 is held by hand to push the fertilizer cart 1, driving the roller 21 and the rotating shaft 20 to rotate. During the movement of the fertilizer cart 1, the Y-shaped axis 14 is driven to move, and then the slotting block 15 is driven to move. The bottom surface of the slotting block 15 sinks into the soil, and then slots are made in the soil, so that seeds and fertilizers are transported into the groove by the feeding component 3, thereby improving the seed planting efficiency.

[0037] For specific embodiment 3, please refer to Figure 1-7 On the basis of the specific embodiment 1 and the specific embodiment 2, a plurality of fixing rods 27 are evenly fixed on the inner wall of the mounting groove 9 in a circular array; an L-shaped piston cylinder 28 is fixed at one end of the fixing rod 27; a piston plate 29 is slidably provided on the inner wall of the L-shaped piston cylinder 28; a piston rod 30 is fixed on the side of the piston plate 29; and one end of the piston rod 30 is fixedly connected to the blocking block 11.

[0038] Specifically, a rotating rod 31 is fixed between the two rotating disks 6; the rotating rod 31 penetrates the side of the hollow circular plate 5 and rotates together; a linkage shaft 32 is fixed to the side of a rotating disk 6; pulleys 33 are respectively fixed to the side surfaces of the linkage shaft 32 and a rotating shaft 20; a belt 34 is provided for transmission between the two pulleys 33.

[0039] Furthermore, a mounting shaft 35 is fixed to the side surface of the circular ring 13; a mounting box 36 is fixed between two mounting shafts 35; the rotating shaft 20 and the mounting box 36 are slidably fitted through each other; two first bevel gears 37 are symmetrically arranged on the inner wall of the mounting box 36 for rotation; second bevel gears 38 that mesh with the two first bevel gears 37 are symmetrically fixed to the side surface of the rotating shaft 20.

[0040] Furthermore, two circular shafts 39 are symmetrically and rotatably arranged on the side of the installation box 36; one end of the two circular shafts 39 is fixedly connected to the two first bevel gears 37 respectively; and a plurality of toggle plates 40 are evenly distributed and fixed on the circumferential side of the circular shaft 39 in a circular array.

[0041] The operation process of this embodiment is as follows: each end of the L-shaped piston cylinder 28 is provided with a sealing plug. In the initial state, all the sealing blocks 11 are aligned with the corresponding receiving holes 10 on the turntable 6, that is, all the receiving slots 8 cannot receive the seeds or fertilizers of the feeding pipe 4. The receiving slot 8 to be used is selected, and the sealing plug on the corresponding L-shaped piston cylinder 28 is removed. Then, air is sucked from the inside of the L-shaped piston cylinder 28 through a suction tool such as a suction pump, thereby driving the piston plate 29 to move closer to the suction pump end, thereby driving the piston rod 30 moves, thereby driving the blocking block 11 to slide, so that the blocking block 11 is disengaged from the material receiving hole 10 on the turntable 6, and finally aligned with another material receiving hole 10 in the corresponding material receiving trough 8, that is, aligned with the material receiving hole 10 on the mounting groove 9, and then the corresponding material receiving trough 8 can receive seeds or feed when it is aligned with the discharge pipe 4. After adjusting the position of the blocking block 11, the sealing plug is put back, so that the air inside the L-shaped piston cylinder 28 cannot circulate, and then the piston plate 29 cannot move, thereby positioning the blocking block 11.

[0042] Then push the fertilizer vehicle 1, drive the slotting block 15 to slot the land first, and at the same time, drive the roller 21 to rotate during the movement of the fertilizer vehicle 1, and then drive the rotating shaft 20 to rotate, and then the rotating shaft 20 drives the pulley 33 thereon to rotate, and then drives another pulley 33 to rotate through the belt 34, and then drives the linkage shaft 32 to rotate, and then drives the corresponding turntable 6 to rotate, and then drives the other turntable 6 to rotate through the linkage shaft 32, so as to realize the synchronous borrowing and unloading of the two unloading components 3.

[0043] When the rotating shaft 20 rotates, the second bevel gear 38 thereon is driven to rotate, and then the second bevel gear 38 drives the corresponding first bevel gear 37 to rotate, and then drives the corresponding circular shaft 39 to rotate, and then the circular shaft 39 drives the toggle plate 40 thereon to rotate, as shown in FIG. Figure 5 As described above, the two circular shafts 39 close to the slotted block 15 rotate in opposite directions, and the toggle plates 40 on the two circular shafts 39 slowly rotate towards each other from vertical upward. When reaching the horizontal state, the corresponding group of toggle plates 40 on the two circular shafts 39 are closest to each other, and then slowly rotate away from each other downward, and the soil on the slot opened in advance by the slotted block 15 is moved to both sides to expand the width of the slot, which is conducive to the feeding of seeds and fertilizers. At the same time, the two circular shafts 39 far away from the slot block 15 rotate in opposite directions, and the toggle plates 40 on the two circular shafts 39 slowly rotate towards each other from vertical downward, pushing the soil previously moved to the side to the middle and covering the seeds and fertilizers under the feeding component 3. When reaching the horizontal state, the corresponding group of toggle plates 40 on the two circular shafts 39 are closest to each other, and then slowly rotate away from each other upward to carry out the next round of soil laying.

[0044] In this embodiment, the first bevel gears 37 on the two rotating shafts 20 drive the corresponding second bevel gears 38 to rotate, and the rotation directions of the two second bevel gears 38 are opposite, and then the rotation directions of the two circular shafts 39 are opposite, and the toggle plates 40 on the two circular shafts 39 close to the slotting block 15 stir the soil to both sides, and the toggle plates 40 on the two circular shafts 39 far away from the slot block 15 spread the soil to the middle, thereby realizing the continuous sequence of slotting, slot expansion and slot burying of the fertilizer spreader 1.
