Description

Technical Field

[0001] The present invention relates to the technical field of crop sowing, in particular to a sowing robot based on upland rice crops. Background Art

[0002] With the acceleration of agricultural modernization, traditional manual sowing methods are gradually being replaced by automated equipment. Upland rice is a rice variety suitable for planting in arid or water-scarce areas. It has high requirements for soil during its planting process and requires precise control of sowing depth and sowing density. Therefore, special mechanical equipment is needed to ensure the adaptability of crop growth. In recent years, more and more farmers and agricultural enterprises have begun to pay attention to precision agriculture and use automated equipment to improve crop growth efficiency and yield.

[0003] However, due to the differences in soil quality in different regions, for example, in water-scarce areas, the soil will become compacted. Even if the soil is loosened, as the climate changes between day and night and the air humidity increases, the soil will condense into lumps. There are large gaps between the soil lumps, resulting in some rice seeds not being able to fully contact the soil and be wrapped by the soil during sowing, which in turn affects germination and is easily eaten by animals such as birds or rats.

[0004] The existing technology includes collecting field soil, making nutrient pots, placing rice seeds into the nutrient pots, and then sowing. However, this process is relatively time-consuming. The produced nutrient pots are easily loosened directly inside the machine due to insufficient soil quality and water content. When the water content of the nutrient pots is increased, such as by applying additional water and fertilizer or directly adding water, the nutrient pots are easily stuck inside the machine, resulting in low practicality and frequent malfunctions. Summary of the Invention

[0005] (1) Technical Problems Solved: In response to the above-mentioned shortcomings of the prior art, the present invention provides a sowing robot based on upland rice crops, which can effectively solve the problems of the prior art.

[0006] (2) Technical solution: To achieve the above objectives, the present invention is implemented through the following technical solution.

[0007] The present invention discloses a seeding robot based on upland rice crops, comprising a accommodating bin, wherein a conveyor belt is provided inside the accommodating bin, and the conveyor belt is used for quantitatively discharging crop particles, a transmission shaft 1 is provided inside the conveyor belt at one end, and a transmission shaft 2 is provided inside the conveyor belt at the other end. The front end of the accommodating bin is fixedly connected to a top sleeve rod, and the bottom end of the top sleeve rod is slidably connected to a bottom insertion rod, and the bottom end of the accommodating bin is symmetrically fixedly connected to two support frames, and two soil-taking hands are symmetrically provided at the bottom ends of the two support frames, and the soil-taking hands are used to perform a cyclic opening and closing operation to take soil following the rotation process of the conveyor belt, and to gather soil balls in situ on the ground during the opening and closing process, and the bottom insertion rod is used to be triggered by the movement cycle of the soil-taking hands to inject crop particles into the center of the soil ball, and a liquid injection mechanism is provided at the bottom end of the accommodating bin, and the liquid injection mechanism is used to synchronously inject nutrient liquid into the center of the soil ball during the process of injecting crop particles into the center of the soil ball.

[0008] Furthermore, the surface of the conveyor belt is evenly provided with receiving grooves, and the interior of the receiving grooves is provided with elastic belts, the edges of the elastic belts are fixedly connected to the inner walls of the receiving grooves, and the top end of the second transmission shaft is evenly fixedly connected with a top block, one end of one of the top blocks extends into the interior of a receiving groove, and the top block conflicts with the elastic belt inside the receiving groove to which it extends.

[0009] Furthermore, the left end of the second transmission shaft passes through the accommodating bin and is fixedly connected to a turntable. The top end of the left side of the turntable is rotatably connected to a movable rocker arm. The bottom end of the movable rocker arm is fixedly connected to a connecting plate, and the connecting plate is sleeved on the surface of the top sleeve rod.

[0010] Furthermore, the left and right ends of the transmission shaft 1 and the transmission shaft 2 are both rotatably connected to the inner wall of the accommodating chamber, and the right end of the transmission shaft 2 passes through the accommodating chamber and extends to the outside of the accommodating chamber.

[0011] Furthermore, the front and rear ends of the bottom surface of the support frame respectively pass through one side of the two soil-taking hands, and the support frame is slidably connected to the soil-taking hands.

[0012] Furthermore, the liquid injection mechanism includes a water pipe, one end of which is fixedly connected to the bottom end of the accommodating chamber, and the side of the water pipe is evenly connected to a water distribution pipe, and the left and right ends of the water distribution pipe are both inserted into the interior of the bottom insertion rod.

[0013] Furthermore, the left end of the water pipe is a water inlet, and the medium transported into the water pipe is diverted to the water distribution pipe and discharged to the top sleeve rod. The water pipe injects the medium synchronously with the descending movement of the bottom insertion rod.

[0014] Furthermore, the bottom ends of the two soil-taking hands are in the shape of a curved shovel, and the two soil-taking hands move closer to or away from each other in a cyclic manner as the transmission shaft 2 continues to circulate.

[0015] Furthermore, tooth blocks are evenly and fixedly connected to the left and right sides of the surfaces of the transmission shaft 1 and the transmission shaft 2, and tooth grooves corresponding to the tooth blocks on the surfaces of the transmission shaft 1 and the transmission shaft 2 are opened on the inner wall of the conveyor belt.

[0016] (III) Beneficial effects: Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The rice seeds are quantitatively taken out by the conveyor belt. As the conveyor belt rotates, the single rice seeds are discharged to the top sleeve rod, and the two soil-taking hands are driven to move down and close together, so that the ground soil is gathered into a ball in situ. As the soil ball inside the two soil-taking hands is fully formed, the bottom insertion rod is inserted into the center of the soil ball, so that the rice seeds are discharged from the top sleeve rod through the bottom insertion rod into the center of the soil ball, thereby achieving accurate seed placement during sowing, ensuring that the number and distribution of seeds at each sowing point are uniform, reducing seed waste, and improving sowing efficiency. With the design of light soil crushing and heavy covering, a soil ball is directly formed on the ground, and the rice seeds are transported to the center so that the rice seeds are fully covered therein to form a ball-shaped soil block containing rice seeds, which is directly generated in the field.

[0017] 2. By setting up a liquid injection mechanism, the nutrient medium enters through the water pipe and is injected into the bottom plug rod through the water distribution pipe, so that the nutrient medium is injected into the soil mass along with the rice seeds, so that nutrient liquid can be injected into the center of the soil mass at the same time as sowing, which helps to enhance the fertility of the soil and improve the germination rate and growth rate of the seeds. It combines the comprehensive operation process of sowing and fertilizing, helps to reduce the time of agricultural activities and improve the overall operation efficiency.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making creative efforts are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1: This embodiment is a sowing robot based on upland rice crops, such as Figures 1-8 As shown, it includes a accommodating bin 1, a conveyor belt 2 is provided inside the accommodating bin 1, and the conveyor belt 2 is used for quantitative crop particle discharge, a transmission shaft 3 is provided at one end of the conveyor belt 2, and a transmission shaft 2 6 is provided at the other end of the conveyor belt 2, the left end of the transmission shaft 2 6 passes through the accommodating bin 1 and is fixedly connected to a turntable 12, the top of the left side of the turntable 12 is rotatably connected to a movable rocker arm 11, the bottom end of the movable rocker arm 11 is fixedly connected to a connecting plate 10, and the connecting plate 10 is sleeved on the surface of the top sleeve rod 8, the left and right ends of the transmission shaft 1 3 and the transmission shaft 2 6 are both rotatably connected to the inner wall of the accommodating bin 1, and the right end of the transmission shaft 2 6 passes through the accommodating bin 1 and extends to the outside of the accommodating bin 1; the left and right sides of the surfaces of the transmission shaft 1 3 and the transmission shaft 2 6 are evenly and fixedly connected with tooth blocks, and the inner wall of the conveyor belt 2 is provided with tooth grooves corresponding to the tooth blocks on the surfaces of the transmission shaft 1 3 and the transmission shaft 2 6.

[0031] The front end of the accommodating bin 1 is fixedly connected with a top sleeve rod 8, and the bottom end of the top sleeve rod 8 is slidably connected with a bottom insertion rod 9. The bottom end of the accommodating bin 1 is symmetrically fixedly connected with two support frames 13. The bottom ends of the two support frames 13 are symmetrically provided with two soil grabbing hands 14. The front and rear ends of the bottom surface of the support frame 13 respectively pass through one side of the two soil grabbing hands 14. The support frame 13 is slidably connected to the soil grabbing hands 14. The soil grabbing hands 14 are used to follow the rotation process of the conveyor belt 2 to perform cyclic opening and closing soil grabbing operations. During the opening and closing process, soil balls are gathered in situ on the ground. The bottom insertion rod 9 is used to follow the movement cycle of the soil grabbing hands 14 to trigger and inject crop particles into the center of the soil ball. The bottom ends of the two soil grabbing hands 14 are curved shovel-shaped. The two soil grabbing hands 14 move closer to or away from each other in a cyclic manner as the transmission shaft 2 6 continues to circulate.

[0032] The surface of the conveyor belt 2 is evenly provided with receiving grooves 4, and the interior of the receiving grooves 4 is provided with elastic belts 5. The edges of the elastic belts 5 are fixedly connected to the inner wall of the receiving groove 4, and the top of the transmission shaft 2 6 is evenly fixedly connected with a top block 7. One end of a top block 7 extends to the interior of a receiving groove 4, and the top block 7 conflicts with the elastic belt 5 inside the receiving groove 4 to which it extends. The elastic belt 5 is made of rubber, has elastic deformation ability, and has rebound ability when not in conflict.

[0033] Compared with the existing technology, the quantitative crop particle emission mechanism ensures that each sowing point has an accurate number of seeds, effectively avoiding the phenomenon of too many or too few seeds that may occur in traditional sowing, thereby improving the consistency of sowing. The design of the soil-taking hand 14 and the bottom insertion rod 9 is used to inject rice seeds into the center of the soil ball, ensuring that the rice seeds are fully covered in the soil, reducing the waste caused by seed scattering or being washed away by wind and rain.

[0034] The design of combining heavy coating and light soil crushing can quickly form soil balls directly on the ground, and in the process, rice seeds can be accurately injected into the center of the soil ball, which significantly improves the sowing efficiency. It is suitable for large-scale farmland operations. During the sowing process, the soil can be gathered in situ to form soil balls, which helps to maintain the structure and moisture of the soil and improve the environmental suitability for crop growth.

[0035] The design's cyclical opening and closing soil-collecting operation and sliding connection structure make the device's movement more flexible and adaptable to different terrain and soil conditions. Compared with traditional manual sowing methods, it can significantly reduce farmers' labor intensity and improve the convenience and efficiency of operations.

[0036] Example 2: In other aspects, this embodiment also provides another optimization mechanism based on Example 1, specifically a liquid injection mechanism for a sowing robot based on upland rice crops, such as Figure 8As shown, a liquid injection mechanism is provided at the bottom end of the storage bin 1, which is used to inject nutrient liquid into the center of the soil mass simultaneously with the process of injecting crop particles into the center of the soil mass. The left end of the water pipe 15 is the water inlet. The water pipe 15 transports the incoming medium to the water distribution pipe 16 and discharges it to the top sleeve rod 8. The water pipe 15 injects the medium synchronously with the descending movement of the bottom insertion rod 9.

[0037] Compared with existing technologies, traditional sowing technology is usually unable to provide nutrient solution around the seeds at the same time. The simultaneous injection of nutrient solution can provide rice seeds with the required moisture and nutrients, promote seed germination and early growth, thereby improving germination rate and survival rate. By injecting the nutrient solution directly into the center of the soil ball, the moisture and nutrient conditions of the soil can be improved in time, which helps to create a suitable growth environment and enhance the soil's nutrient supply capacity. The effect is more obvious in arid or barren soils. Since the nutrient solution is injected simultaneously during sowing, it ensures that the nutrients can be evenly distributed around the seeds, which helps each seed to obtain sufficient nutrition, thereby promoting uniform growth.

[0038] Working principle: Before using the present invention, the user installs the device to the front end of an agricultural tractor with walking ability and fixes it by screwing. The user needs to install the motor at the right end of the storage compartment 1, such as Figure 5 As shown, the output shaft of the motor is fixedly connected to the right end of the transmission shaft 26, as shown in FIG. Figure 6 As shown, a water pump is installed at the right end of the water pipe 15 so that the water outlet of the water pump is connected to the water pipe 15, and the water inlet of the water pump is connected to an external water source. The water pump supplies water intermittently, and the triggering condition for water supply is the descent of the bottom plug rod 9.

[0039] In the specific implementation of the present invention, the user can inject rice seeds into the storage bin 1 through the top of the storage bin 1, start the motor, rotate the transmission shaft 2 6, and through the coordinated transmission of the transmission shaft 1 3, the conveyor belt 2 relies on the transmission shaft 1 3 and the transmission shaft 2 6 to rotate in a cycle. Figure 2 As shown, a single rice seed first enters the receiving groove 4 at the upper half of the top of the conveyor belt 2. As the conveying progresses, the receiving bin 1 blocks the excess rice seeds at the upper half of the top of the conveyor belt 2, and the single rice seed is transported to the lower half of the conveyor belt 2. At this time, the top block 7 contacts the elastic belt 5 and pushes into the receiving groove 4, so that the rice seeds originally in the receiving groove 4 are pushed out, and the rice seeds slide through the conveyor belt 2 and slide into the top sleeve rod 8.

[0040] During the rotation of the transmission shaft 2 6, the turntable 12 is synchronously driven to rotate, and the turntable 12 drives the movable rocker arm 11 to rotate eccentrically, so that the movable rocker arm 11 pulls the connecting plate 10 to swing back and forth. Under the limitation of the support frame 13 on the moving trajectory of the soil-taking hand 14, the connecting plate 10 drives the bottom insertion rod 9 to reciprocate and extend in the top sleeve rod 8. During this process, the soil-taking hand 14 slides back and forth at the bottom end of the support frame 13, so that the two soil-taking hands 14 continuously move down and gather together and then rise and separate. In the process of descending and gathering, the ground soil is condensed into a soil ball body. At this time, the bottom insertion rod 9 moves downward synchronously with the gathering of the soil-taking hands 14 and is inserted into the center of the soil ball body, so that the rice seeds that originally slid into the top sleeve rod 8 enter the center of the soil ball body through the bottom insertion rod 9.

[0041] As the bottom rod 9 descends, the water supply operation of the water pipe 15 is triggered, so that the nutrient medium is diverted through the water pipe 15 to the water distribution pipe 16, and then injected into the bottom rod 9 through the water distribution pipe 16, and injected into the center of the soil ball along with the rice seeds. As the tractor continues to move forward and the drive shaft 2 6 continues to rotate, the sowing work is continuously completed.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
