Description

Technical Field

[0001] The invention relates to the field related to plant planting, and in particular to a plant cultivation device and method based on saline-alkali land. Background Art

[0002] Salt-alkali land has the following characteristics: 1. Poor soil structure: The soil structure of saline-alkali land is poor, easy to compact, low in organic matter, poor in nutrients, and weak in soil fertility retention. These characteristics lead to low fertility in saline-alkali land, affecting crop growth13; 2. Impact on crop growth: Due to the high salt content in the soil, saline-alkali land is usually not suitable for the growth of ordinary crops. When the soil salt content exceeds 0.1%, the growth of ordinary crop varieties begins to be affected; when the salt content exceeds 0.3%, the yield of most crop varieties decreases significantly; 3. High salt content in the soil: The main feature of saline-alkali land is the high salt content in the soil, which usually exceeds 0.1%. When the salt content exceeds 0.3%, the growth of most crops will be seriously affected. 1. The salt in the soil of saline-alkali land is mainly sodium chloride and sodium sulfate. These salts gather on the surface of the soil to form white salt crust.

[0003] After searching, a household agricultural planting device was disclosed, with the announcement number: CN107197643B; The advantages of this device are: it uses solar power generation devices to generate electricity, saves energy and reduces costs; the width of the support platform can be adaptively adjusted to be suitable for sowing in different geographical environments; the planting device is light and small in size, simple to operate, and easy to store, making it suitable for home use.

[0004] However, this type of device is not suitable for saline-alkali land, because the main problem of planting in saline-alkali land is the compaction of the land.

DETAILED DESCRIPTION

[0030] 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.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] For example, see Figures 1 to 13 A plant cultivation device based on saline-alkali land comprises a support plate 1 and a vehicle body, wherein the support plate 1 comprises a receiving frame, a mounting plate is fixed to one side of the receiving frame, and the support plate 1 is fixed to the rear end of the vehicle body through the mounting frame, and further comprises: A transmission ring 2, wherein the transmission ring 2 is rotatably mounted on the support plate 1; A support ring 7, on which a plurality of bucket claws 701 are hinged, and the plurality of bucket claws 701 are connected to a flip assembly installed on the support ring 7, and a protective shell 702 for protection is fixed on the support ring 7, and the protective shell 702 is connected to the transmission ring 2 through a lifting assembly, and the transmission ring 2 is connected to a driving member installed on the support plate 1; A seedling supply assembly, the seedling supply assembly is mounted on the vehicle body; A crushing assembly is arranged at the bottom of the transmission ring 2 .

[0033] In the embodiment of the present invention, the support plate 1 and all parts installed on the support plate 1 are driven to move by the movement of the vehicle body; The driving member drives the transmission ring 2 to rotate, and when the transmission ring 2 rotates, the lifting assembly drives the support ring 7 and the bucket claw 701 to rotate, and at the same time, the lifting assembly drives the support ring 7 and the bucket claw 701 to be vertically lowered; Among them, under normal conditions, the bucket claw 701 is in an open state. When the bucket claw 701 rotates and descends, when the bucket claw 701 contacts the ground, since the bucket claw 701 is in an open state, its end face is annular serrated. The ground is cut by the rotation and descent of the bucket claw 701, so that a ring-shaped incision is formed on the ground, and the bucket claw 701 is embedded in the ground. Then, the multiple bucket claws 701 are driven to flip through the flip assembly, so that the bucket claws 701 are closed to form a cone. In this process, most of the soil will be captured into the bucket claw 701, and then the closed bucket claw 701 is driven to rise by the lifting assembly. When the bucket claw 701 rises to the end of the stroke, the soil in the bucket claw 701 is crushed by the crushing assembly to make the soil finer and make crops such as reeds / phragmites easier to take root. In addition, a certain amount of fertilizer can be added to the bucket claw 701 during the crushing process to make the soil more fertile. After the soil in the bucket claw 701 is crushed, it is vertically lowered. After it is lowered to the end of the stroke, the bucket claw 701 is still in the cut "pit". At this time, multiple bucket claws 701 can be driven to open, so that the soil falls into the "pit", and then the reed seedlings are inserted into the "pit" through the seedling supply assembly, and then the support ring 7 and the bucket claw 701 are raised again to complete the planting of a single reed; By repeating the above steps and coordinating with the movement of the vehicle body, the seeds can be planted at any possible planting position.

[0034] When the soil in the bucket claw 701 is crushed, a certain amount of waste material can be added to the bucket claw 701. The general idea is to install a feed box on the transmission ring 2, and a quantitative unloading mechanism connected to the feed box is installed at the bottom of the feed box. The triggering of the quantitative unloading mechanism is based on the cooperation between the bucket claw 701 and the crushing assembly. Of course, there are many ways to implement the quantitative unloading mechanism. The present invention only provides one idea here, and its specific implementation shall be subject to actual production.

[0035] The driving member includes a No. 2 motor 501 fixed on the support plate 1 , and the output shaft of the No. 2 motor 501 is connected to the transmission ring 2 through a No. 1 transmission chain 101 .

[0036] In the embodiment of the present invention, when the second motor 501 is working, its output shaft drives the transmission ring 2 to rotate through the first transmission chain 101; The transmission ring 2 can be driven to rotate by the second motor 501, or it can be connected to the power system of the vehicle body through a transmission structure. These two methods can be selected according to actual needs and are not specifically limited in the present invention. Among them, the vehicle body is the most common tractor, and the power source of the tractor is connected to the transmission ring 2, which is the same as the connection method between the rotary tiller and the tractor in the prior art.

[0037] The crushing assembly includes a blocking plate 4 fixed to the bottom of the transmission ring 2, the blocking plate 4 is coaxially arranged with the transmission ring 2, a No. 1 motor 5 is coaxially fixed to the blocking plate 4, a crushing shaft 401 is coaxially rotatably installed at the bottom of the blocking plate 4, and the crushing shaft 401 is fixed to the output shaft of the No. 1 motor 5; The crushing shaft 401 comprises a central shaft, on which a plurality of crushing pieces are fixed at equal circumferential or spiral distances.

[0038] In the embodiment of the present invention, when the No. 1 motor 5 is working, its output shaft drives the crushing shaft 401 to rotate; After the bucket claw 701 grabs the soil, it rises. When the bucket claw 701 rises to the end of its stroke, the top of the bucket claw 701 is blocked by the blocking plate 4, and the soil in the bucket claw 701 is crushed by the rotation of the crushing shaft 401; The blocking of the bucket claw 701 by the blocking plate 4 is to prevent the soil from being scattered outside the bucket claw 701 during crushing.

[0039] Embodiment 2 is distinguished from Embodiment 1 in that: the lifting assembly comprises three guide rods 6 which are equidistantly arranged on a circumference, the three guide rods 6 all penetrate the transmission ring 2 and are slidably connected to the transmission ring 2, and the three guide rods 6 are all fixed to the protective shell 702; Three threaded sleeves 301 are fixed on the transmission ring 2 at equal intervals around the circumference, and screw rods 3 threadedly matched therewith are installed in the three threaded sleeves 301. The three screw rods 3 are rotatably connected to the protective shell 702, and the three screw rods 3 are also connected to the transmission part installed at the bottom of the support plate 1.

[0040] In the embodiment of the present invention, when the transmission ring 2 rotates, the protective shell 702 is driven to rotate through the three guide rods 6 and the three screw rods 3, so as to drive the bucket claw 701 to rotate through the support ring 7; During the rotation of the guide rod 6 and the screw rod 3, the cooperation between the screw rod 3 and the transmission parts drives the screw rod 3 to rotate around the center of the transmission ring 2 while rotating on its own, so that when the screw rod 3 rotates on its own, it drives the screw rod 3 to vertically descend / ascend through the thread cooperation with the threaded sleeve 301, and then drives the protective shell 702, the support ring 7, and the bucket claw 701 to descend / ascend synchronously through the screw rod 3.

[0041] The transmission member includes a No. 1 driven gear 303 coaxially fixed on the three screw rods 3, a No. 1 gear ring 302 is arranged at the bottom of the transmission ring 2, the rack in the No. 1 gear ring 302 is arranged in three sections, and the three sections of the rack are arranged equidistantly, and the No. 1 gear ring 302 is fixed to the bottom of the support plate 1 through a bracket.

[0042] In the embodiment of the present invention, when the screw rod 3 rotates around the center of the transmission ring 2, it drives the first driven gear 303 to follow the movement. While the first driven gear 303 rotates around the center of the transmission ring 2, it rotates by meshing with the rack of the first gear ring 302, and then the screw rod 3 is driven to rotate by the rotation of the first gear ring 302. The reason and effect that the rack inside the No. 1 gear ring 302 is segmented rather than a complete rack is that, since the bucket claw 701 is in a rotating state, the No. 1 driven gear 303 meshes with the rack of the No. 1 gear ring 302, corresponding to the bucket claw 701 being vertically lowered. If the rack of the No. 1 driven gear 303 is completely set, when the transmission ring 2 rotates, it will directly drive the bucket claw 701 to be inserted deep into the ground, causing the bucket claw 701 to be easily bent due to excessive force on the screw rod 3 and the guide rod 6 when the bucket claw 701 rotates; In the present invention, the rack of the first gear ring 302 is arranged into multiple sections, so that the bucket claw 701 can be slowly inserted into the ground.

[0043] The flip assembly includes a second gear ring 704 rotatably mounted on the support ring 7, and the second gear ring 704 is connected to a plurality of bucket claws 701 through a plurality of transmission assemblies; The transmission assembly includes a No. 2 transmission shaft 7010 that penetrates the support ring 7 and is rotatably connected to the support ring 7, a No. 2 driven gear 705 is coaxially fixed on the No. 2 transmission shaft 7010, and the No. 2 driven gear 705 is meshed with the No. 2 gear ring 704; A No. 1 transmission shaft 708 is rotatably mounted on both sides of the rotating shaft of the bucket claw 701. The two No. 1 transmission shafts 708 are respectively connected to the rotating shaft of the bucket claw 701 through a bevel gear set 709. A worm gear 707 is coaxially fixed on the two No. 1 transmission shafts 708. A worm 706 cooperating with the worm gear 707 is rotatably mounted on one side of the worm gear 707. The two worms 706 are connected to the second transmission shaft 7010 via a second transmission chain 7011 . A third motor 502 is fixed on the protective shell 702 . A driving gear 703 is coaxially fixed on the output shaft of the third motor 502 . The driving gear 703 is meshed with the second gear ring 704 .

[0044] In the embodiment of the present invention, when the third motor 502 is working, the output shaft drives the driving gear 703 to rotate. When the driving gear 703 rotates, the second gear ring 704 is driven to rotate by meshing with the second gear ring 704. The rotation of the second gear ring 704 synchronously drives the plurality of second driven gears 705 and the second transmission shaft 7010 to rotate. When the second transmission shaft 7010 rotates, the plurality of worms 706 are driven to rotate synchronously through the second transmission chain 7011. When the worm 706 rotates, it drives the first transmission shaft 708 to rotate through the cooperation with the worm wheel 707, and the first transmission shaft 708 drives the multiple bucket claws 701 to turn synchronously through the bevel gear set 709; The cooperation between the worm 706 and the worm wheel 707 can make the bucket claw 701 have a self-locking characteristic when turning over, so that when the bucket claw 701 turns over and carries soil, the bucket claw 701 will not turn over in the opposite direction due to the weight of the soil inside; It should be noted that the bevel gear set 709 in the present invention includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed with the rotation of the first transmission shaft 708 and the bucket claw 701 respectively; Through the above-mentioned movement state, multiple bucket claws 701 can be turned over synchronously, and they are self-locking when turning over. When the bucket claws 701 are in an open state to cut the ground, if the bucket claws 701 are turned over, it will cause the ground cutting shape to have no notches, and it is easy to damage the bucket claws 701 and cause them to deform.
