Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree cultivation, in particular to a fruit tree cultivation fertilization and root irrigation device. Background Art

[0002] In the modern fruit tree cultivation industry, the traditional fertilization and root irrigation model is facing the dual challenges of efficiency and technology. The current orchard planting scale is expanding. Artificial trench fertilization and flooding root irrigation not only consume a lot of manpower and material resources, but also have problems such as difficulty in unifying the fertilization depth and uneven distribution of water and fertilizer. As a result, the fertilizer utilization rate is generally less than 30%, and the water resource waste rate is as high as more than 40%. The root system of fruit trees is the core organ for nutrient absorption. Its distribution depth and range vary significantly with the age of the tree, variety and soil structure (for example, the adult roots of apple trees are mainly concentrated in the 20-60cm soil layer). Traditional operation methods are difficult to accurately match the root nutritional needs. Fertilization is often too shallow, causing the roots to float, or too deep, resulting in fertilizer loss.

[0003] Existing fruit tree cultivation fertilization and root irrigation devices usually require drilling first and then fertilizing. The steps are cumbersome, time-consuming and manpower-consuming, and require the use of multiple tools. The operation is complicated and labor-intensive. In addition, the traditional surface fertilization method cannot ensure that the fertilizer can penetrate deeply into the root system of the fruit tree, and the fertilization uniformity is poor, resulting in low fertilizer utilization rate. At the same time, after use, the drill bit of the traditional fertilization and root irrigation device is easily contaminated with mud and other blockages, which requires additional cleaning. If the blockage is not cleaned in time, it may dry and harden, increasing the difficulty of cleaning and reducing the efficiency of fertilization and root irrigation. Therefore, a fruit tree cultivation fertilization and root irrigation device is proposed. Summary of the Invention

[0036] The above scheme is adopted: by setting the cooperation of the first piston rod 103 and the drill bit 201 and other structures, it is convenient to fertilize and irrigate the fruit trees. The handle 102 is held by the hand to bring the device to the fruit tree that needs to be fertilized and irrigated. The diameter of the fruit tree is smaller than the diameter of the inner fan surface of the pressure plate 101, so that the inner fan surface of the pressure plate 101 fits the fruit tree. Then one foot steps on the pedal 302 and presses the handle 102 downward to drive the pressure plate 101 to move downward in the slide groove 303, driving the sleeve 105 and the first piston rod 103 downward. The downward movement of the sleeve 105 will apply stress to the inner wall of the arc groove 202 through the protrusion 106, and the drill bit 201 is driven to rotate by the stress, and the rotation of the drill bit 201 will cause its bottom The blunt arc blade of the first piston rod 103 drills into the soil, and the downward movement of the first piston rod 103 compresses the space in the first cavity 203, so that the water and fertilizer in the first cavity 203 are discharged through the plurality of discharge holes 204, fertilizing and root irrigating the fruit trees, avoiding the tedious steps of traditional fertilization and root irrigation, which requires drilling holes before fertilizing, saving time and labor costs, simple and convenient operation, reducing labor intensity, and improving the efficiency of fertilization and root irrigation.

[0037] like Figures 5 to 8As shown, the base mechanism 3 includes a base shell 301, a pedal 302 is fixedly connected to the side of the base shell 301, a slide groove 303 is provided on the top of the base shell 301, and two second piston rods 304 are fixedly connected to the inner wall of the slide groove 303. Two second rotating grooves 305 are provided inside the base shell 301, and a number of water nozzles 306 are evenly provided on the bottom of the base shell 301. Two folding tubes 307 are fixedly connected to the inner wall of the slide groove 303, the folding tubes 307 are located on the side of the second piston rod 304, and the bottom of the folding tubes 307 is communicated with the inside of the second rotating groove 305. Several water nozzles 306 are respectively communicated with the two second rotating grooves 305. The shape of the base shell 301 is adapted to the shape of the pressure plate 101, and the pedal 302 is located on the side with the larger fan surface of the base shell 301.

[0038] Three drill bits 201 are rotatably connected to the bottom of the base shell 301. The part of the drill bit 201 with the arc groove 202 passes through the bottom of the base shell 301 and extends to the inside of the slide groove 303. The two second piston rods 304 are staggered between the three drill bits 201 respectively. The water outlet 306 is away from the side of the second rotating groove 305 toward the drill bit 201, and the partition 107 is slidably connected to the inner wall of the slide groove 303.

[0039] A cleaning mechanism 4 is provided inside the pressing mechanism 1, and the cleaning mechanism 4 includes two second cavities 401 provided inside the pressing plate 101, two third rotating grooves 402 provided inside the pressing plate 101, two water supply grooves 403 provided on the top of the pressing plate 101, and two water supply pipes 404 and two material supply pipes 405 provided on the top of the pressing plate 101.

[0040] The third rotating groove 402 is located on the side of the second cavity 401, and the water trough 403 is connected to the interior of the second cavity 401 through the third rotating groove 402. The two second piston rods 304 respectively pass through the bottom of the pressure plate 101 and extend to the interior of the second cavity 401. The top of the folding tube 307 is fixedly connected to the bottom of the pressure plate 101, and the top of the folding tube 307 is connected to the interior of the second cavity 401. The water pipe 404 is connected to the water trough 403, and the material pipe 405 is connected to the material trough 104.

[0041] The above scheme is adopted: by setting the cooperation of the second piston rod 304 and the water spray port 306 and other structures, it is convenient to clean the drill bit 201. When the pressure plate 101 is downward, the second piston rod 304 will be close to the second rotating groove 305 to generate negative pressure, sucking the water in the water tank into the second cavity 401 and folding the folding tube 307. When fertilizing and root irrigation is completed, the handle 102 is lifted upward to drive the pressure plate 101 upward, which will cause the second piston rod 304 to squeeze the water in the second cavity 401, so that it opens the rotating plate 109 in the second rotating groove 305 through the folding tube 307, and finally cleans the drill bit 201 during the rotation process through the water spray port 306. The cleaning action is triggered synchronously with the upward action of the handle 102, that is, the cleaning is performed immediately after the fertilizing and root irrigation is completed, avoiding the blockage from drying and hardening. There is no need to clean the device additionally, thereby improving the continuity of the fertilizing and root irrigation work and improving work efficiency. At the same time, the cleaned water can also be used to irrigate the surface around the fruit trees.

[0042] The working principle and usage process of the present invention are as follows: first, the feed pipe 405 is connected to the backpack storing water and fertilizer. At the same time, a water storage area is set inside the backpack, and the water pipe 404 is connected to the water storage area. At this time, the water and fertilizer will press downward through the feed pipe 405 and the feed trough 104 under the action of their own gravity to press the rotating plate 109 in the first rotating groove 108, causing the rotating plate 109 to rotate and open the passage between the feed trough 104 and the first cavity 203, and squeeze the elastic member 110, allowing the water and fertilizer to enter the first cavity 203. When the first cavity 203 is full of water and fertilizer, the rotating plate 109 will return to its original position under the elastic force of the elastic member 110. Similarly, inside the second cavity 401, some water will be stored on the side of the second piston rod 304 near the second rotating groove 305.

[0043] Then, holding the handle 102, the device is brought to the fruit tree that needs fertilization and root irrigation. The diameter of the fruit tree is smaller than the diameter of the inner fan surface of the pressing plate 101, so that the inner fan surface of the pressing plate 101 fits the fruit tree. Then, one foot steps on the pedal 302 and presses the handle 102 downward to drive the pressing plate 101 downward in the slide groove 303, driving the sleeve 105 and the first piston rod 103 downward. The downward movement of the sleeve 105 will apply stress to the inner wall of the arc groove 202 through the protrusion 106, and the drill bit 201 is driven to rotate by the stress. The rotation of the drill bit 201 causes the blunt arc blade at the bottom to drill into the soil, and the downward movement of the first piston rod 103 will compress the space in the first cavity 203, so that the water and fertilizer in the first cavity 203 are discharged through the plurality of discharge holes 204, so as to fertilize and irrigate the fruit tree.

[0044] During the downward movement of the pressing plate 101, negative pressure will be generated on the side of the second piston rod 304 close to the second rotating groove 305, which will suck the water in the water tank into the second cavity 401 and fold the folding tube 307. When the fertilization and root irrigation are completed, the handle 102 is lifted upward to drive the pressing plate 101 upward, which will cause the second piston rod 304 to squeeze the water in the second cavity 401, so that the rotating plate 109 in the second rotating groove 305 will be opened through the folding tube 307, and finally the drill bit 201 in the rotating process will be cleaned through the water nozzle 306. Finally, the device is moved to the other side of the fruit tree and the above steps are repeated.
