Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a land fertilization system based on big data. Background Art

[0002] Agricultural machinery refers to various machines used in the production of crops and animal husbandry, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilizing machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery, and agricultural transport machinery. Due to the development of social industrialization, the use of agricultural machinery for agricultural production has become familiar to the general public. Using fertilizer machinery to fertilize the land is one of these categories. When using fertilizer machinery for work, the following problems may arise, and these problems need to be solved with the cooperation of big data technology:

[0003] 1. Using fertilizer machinery to fertilize the land can only fertilize the land evenly. However, due to the large area of the land, the fertility of each area is different. If the same amount of fertilizer is applied to all the land, the fertility of the land will be different. Some areas have greater fertility, while some areas are even lacking fertilizer, which will affect the growth of crops and is not conducive to crop yields.

[0004] 2. When using fertilizer machinery to fertilize the land, it is generally done by spreading fertilizer. After this method of fertilization, the fertilizer will only be scattered on the surface. With the wind and sun, a large amount of fertilizer will be lost, affecting the fertility;

[0005] 3. Existing fertilizer machinery requires farmers to drive to complete the fertilization work, which consumes a lot of manpower and requires certain driving skills. The threshold is high and it is not easy to popularize agricultural machinery. Summary of the Invention

[0015] Beneficial effects

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] 1. By setting up a mounting plate and designing 5 soil measuring instruments on the mounting plate, a five-point test can be performed on a small piece of soil through the measurement of the soil measuring instrument, and then the salinity, humidity, and pH value of the small piece of soil can be detected. Based on the measured data combined with big data deduction, the amount of fertilizer required on the small piece of soil can be calculated, and then the soil can be fertilized in a targeted manner. Through continuous testing and fertilization, the targeted fertilization of the entire plot of land can be completed, so that the fertility of the entire plot of land is uniform, and there will be no phenomenon of excessive fertility or lack of fertilizer;

[0018] 2. By setting up multiple silos and fertilizer rods, when fertilizing, the fertilizer rods are inserted into the ground, and the control rods are driven to open the lower ends of the fertilizer rods, thereby supporting space under the ground, so that the fertilizer can fall below the ground, avoiding the loss of fertilizer due to wind and sun, preserving fertility, and making the fertilizer closer to the roots of the plants, so that the fertilizer can be better absorbed by the plants, which is beneficial to the growth of the plants;

[0019] 3. By providing a first through hole on the fertilizing rod, a boss on the control rod, and a sliding plug on the control rod, the sliding plug can be driven to slide by the first electric push rod. When the amount of fertilizer required for a small piece of soil is obtained through big data analysis, the position of the sliding plug is controlled. Through the cooperation of the sliding plug, the boss and the first through hole, the outflow of fertilizer can be controlled, thereby completing targeted fertilization of the soil. This is convenient, fast and simple to control.

[0020] 4. By arranging the soil measuring instrument and the fertilizing rod on the upper and lower sides of the silo, the soil can be measured first and then fertilized by driving the silo to flip through the first motor. At the same time, by driving the upper connecting rod, the silo can be flipped to the right to drive the soil measuring instrument for detection. The upper connecting rod drives the mobile frame to move to the right to detect the small piece of soil in front. When the silo flips to the left, the upper connecting rod and the mobile frame cooperate to drive the silo to move to the right, so that the fertilizing rod fertilizes the soil that has just been tested. After fertilizing a small piece of soil, the walking direction of the equipment can be changed through the support plate, thereby realizing the fertilization of the entire piece of soil. This working process can be completed by the control of a first motor, saving costs. At the same time, no human driving is required, and the threshold for use and promotion is low.

Since the third bevel gear 61 and the first bevel gear 62 are respectively engaged with the second bevel gear 63, the first bevel gear 62 is driven to rotate clockwise. Since the first bevel gear 62 and the intermediate shaft 65 are fixed The first pawl 94 and the first spring piece 93 cannot drive the intermediate shaft 65 to rotate, so that the main bracket 51 is driven to move to the right by a distance under the cooperation of the movable frame 57, the upper connecting rod 561, the lower connecting rod 562 and the protruding rod 57a, thereby causing the fertilizing rod 15 to move to the right and come to the top of the soil just tested. The double-headed electric push rod 31 is controlled to drive the hopper 11 to move downward, so that the front end of the control rod 13 is inserted into the ground, and the control rod 13 is pushed upward until it touches the end cover 12. At this time, the boss 131 enters the first through hole 112, and the sliding plug 74 enters the hopper 11a, the fertilizer falls into the first through hole 112 and is placed on the boss 131, the first electric push rod 73 is controlled to be extended and retracted, and then the distance between the sliding plug 74 and the boss 131 is controlled, thereby controlling the amount of fertilizer applied. At the same time, due to the upward movement of the control rod 13, the support rod 71 is driven to separate through the first connecting rod 72, and a space is created under the soil. Then, the double-headed electric push rod 31 is controlled to drive the hopper 11 to rise, the sliding plug 74 enters the first through hole 112, and the boss 131 enters. The fertilizer enters the first chamber 111, and the fertilizer between the sliding plug 74 and the boss 131 falls into the lower end of the fertilizing rod 15 through the second through hole 11b, and then the first electric push rod 73 is controlled to fully retract, driving the sliding plug 74 to descend, and then the double-headed electric push rod 31 is controlled to extend again, and the control rod 13 is controlled to rise. The sliding plug 74 will not enter the silo 11a due to its descending position, and the silo 11a will be blocked. At the same time, the support rod 71 is separated, and the waste material is put into the soil, completing the fertilization of a piece of soil; through continuous circulation, the land in a straight line can be fertilized.

[0039] When fertilizing a piece of land is completed, the second electric push rod 55 can be controlled to extend, driving the support plate 54 to move downward to prop up the equipment, and then the first motor 41 is started to drive the equipment to change the moving direction through the engagement of the fourth bevel gear 44 and the fifth bevel gear 43, so that the entire piece of land can be fertilized to complete the fertilization work.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
