Description

Technical Field

[0001] The invention relates to the field of mango planting, and more specifically to a device and method for accurately supplying water and fertilizer to a mango root crown area. Background Art

[0002] Fertilizing the root crown area of ​​mangoes is mainly to reduce nutrient loss in fertilizer management during mango planting, thereby promoting the healthy growth of mango tree roots, expanding the crown, enhancing tree vigor, and improving fruit quality. In addition, fertilizing the root crown area can also improve soil structure, increase soil fertility, and create a more suitable growth environment for mango trees. In short, fertilizing the root crown area of ​​mangoes is an effective means to increase mango yield, improve fruit quality, and ensure the healthy growth of fruit trees.

[0003] At present, the common method of fertilizing mango trees is to dig circular or semi-circular ditches outside the drip line of the mango tree crown, that is, the edge of the crown projection and the ground position where water naturally drips. Then, fertilizer is evenly applied to these ditches and covered with soil so that the fertilizer can be slowly released and penetrated into the soil for root absorption.

[0004] However, this fertilization method cannot directly deliver fertilizer to the most critical absorption area of ​​the mango tree, namely the root crown area, which is the area at the bottom of the crown where the roots are most dense and active. In addition, if it rains, especially when the rainfall is heavy or lasts for a long time, the applied fertilizer will easily be lost with the rain, causing the nutrient concentration in the soil to drop rapidly, which will not only reduce the utilization rate of the fertilizer, but also restrict the growth of some roots because they cannot access enough nutrients, thus affecting the healthy growth and yield of the entire mango tree.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0040] Existing fertilization methods cannot directly deliver fertilizer to the most critical absorption area of ​​mango trees, namely the root crown area.

[0041] The root crown zone of the mango tree, as the core area of ​​tree growth and development, refers to the area where the roots are the most dense and active at the bottom of the crown. This area is not only the main place for the mango tree to absorb water and mineral nutrients, but also an important part for the tree to respire, synthesize organic matter and store nutrients.

[0042] In addition, if the existing fertilization method encounters rainy weather, especially when the rainfall is heavy or lasts for a long time, the applied fertilizer will easily be lost with the rain, causing the nutrient concentration in the soil to drop rapidly. This will not only reduce the utilization rate of the fertilizer, but also limit the growth of some roots because they cannot access sufficient nutrients, thereby affecting the healthy growth and yield of the entire mango tree.

[0043] The present application provides a device and method for accurately supplying water and fertilizer to the root crown area of ​​mangoes, which can achieve precise fertilization, ensure that the fertilizer directly acts on the root crown area of ​​the mango tree, reduce nutrient loss, improve fertilizer utilization, and promote the healthy growth of the mango tree.

[0051] like Figure 1 and Figure 4-Figure 8 As shown, a steering assembly 3 is installed on the driving assembly 1, and the steering assembly 3 is used to control the moving angle of the pressure assembly 4.

[0052] The steering assembly 3 includes a support tube 301, an end of the support tube 301 passes through the lifting plate 108 and is fixedly connected thereto, a mounting sleeve 302 is fixedly connected to the bottom of the support tube 301, a fixing ring 303 is fixedly connected to the circumferential outer wall of the mounting sleeve 302, a connecting tube 314 is fixedly connected to the bottom of the support tube 301, a sliding sleeve 320 is slidably connected to the circumferential outer wall of the mounting sleeve 302, and a connecting sleeve 304 is fixedly connected to the bottom of the sliding sleeve 320.

[0053] Two sliding rods 305 are fixedly connected to the top of the sliding sleeve 320. The top of the sliding rod 305 passes through the fixed ring 303 and is slidably connected to it. The circumferential outer wall of the sliding rod 305 is sleeved with a spring 306. The circumferential outer wall of the sliding rod 305 is fixedly connected with a limiting sleeve 307. One end of the spring 306 is fixedly connected to the limiting sleeve 307, and the other end of the spring 306 is fixedly connected to the fixed ring 303. The inner wall of the mounting sleeve 302 is fixedly connected with a second supporting ring 311. The inner wall of the second supporting ring 311 is sleeved with a rotatable second hemisphere 313. The inner wall of the second hemisphere 313 is fixedly connected with an insertion rod 310, and the top of the insertion rod 310 is fixedly connected to the connecting pipe 314.

[0054] The outer circumferential wall of the insertion rod 310 is slidably connected to the first hemisphere 309, and two lifting grooves 321 are provided on the outer circumferential wall of the insertion rod 310. The inner walls of the lifting grooves 321 are slidably connected to the lifting blocks 322. The inner walls of the first hemisphere 309 are respectively fixedly connected to the two lifting blocks 322. The outer circumferential wall of the first hemisphere 309 is sleeved with a rotatable first supporting ring 308. The outer circumferential wall of the first supporting ring 308 is fixedly connected to the inner wall of the connecting sleeve 304, and the ends of the first supporting ring 308 and the second supporting ring 311 are both provided with steering grooves 312.

[0055] Two second fixed blocks 315 are fixedly connected to the top of the fixing ring 303, and a rotating shaft 316 is rotatably connected between the two second fixed blocks 315.

This simple operation method reduces labor intensity and improves the efficiency of fertilization operations. Embodiment 4:

[0058] This embodiment provides a device and method for accurately supplying water and fertilizer to the root crown area of ​​mango, which further includes the following structures based on the third embodiment:

[0059] like Figure 1 and Figure 9-13 As shown, a pressure-applying assembly 4 is installed at the bottom of the steering assembly 3, and the pressure-applying assembly 4 is used to apply pressure to the soil.

[0060] The pressure-applying assembly 4 includes a punch 401, the end of which is fixedly connected to the insertion rod 310, a water chamber 402 is provided at the top of the punch 401, a rotating groove 403 is provided at the bottom of the inner wall of the water chamber 402, an extension groove 404 is provided on the inner wall of the rotating groove 403, a plurality of expansion grooves 405 are provided on the inner wall of the rotating groove 403, a connecting shaft 406 is rotatably connected to the inner wall of the rotating groove 403, a roller 408 is fixedly connected to the circumferential outer wall of the connecting shaft 406, the roller 408 is located inside the rotating groove 403, and a plurality of crushing knives 409 are fixedly connected to the circumferential outer wall of the roller 408.

[0061] Both ends of the connecting shaft 406 are fixedly connected with rotating blocks 407, which are respectively fixedly connected to rollers 408. The rollers 408 and the two rotating blocks 407 are combined to form a complete sphere. The outer walls of the rotating blocks 407 are provided with two guide grooves 410. A vertical surface 411 is provided on one side of the inner wall of the guide groove 410. The vertical surface 411 is tangent to the inner wall of the guide groove 410. By setting the guide groove 410 and the vertical surface 411, the soil embedded inside can be easily removed under the pressure of water and fertilizer, thereby avoiding poor flow of water and fertilizer.

[0062] When encountering hard stones, the punch 401 can automatically adjust the moving direction, quickly get rid of the obstruction of the stones through the rolling of the roller 408, and continue to move downward to apply fertilizer; this highly adaptable feature enables the operation method to perform fertilization operations under different terrains and soil conditions, thereby improving the flexibility and efficiency of fertilization.

[0063] Working principle: Water and fertilizer are injected into the water and fertilizer tank 201 through the water injection pipe 202. When the punch 401 moves to the position close to the root crown of the mango tree, the pressure pump 203 pressurizes the water and fertilizer in the water and fertilizer tank 201 and transports it to the fixed pipe 205. The water and fertilizer enter the insertion rod 310 through the fixed pipe 205, the corrugated telescopic pipe 207, the support pipe 301, and the connecting pipe 314, and enter the punch 401 through the insertion rod 310, and are sprayed into the soil around the root tube of the mango tree through the guide groove 410 on the rotating block 407, so as to achieve precise fertilization;

[0064] When the punch 401 moves in the soil, the roller 408 encounters a hard stone. At this time, the motor 102 is turned off, the connecting sleeve 304 is pushed upward to drive the sliding sleeve 320 to move upward, and the sliding sleeve 320 pushes the sliding rod 305 to slide upward along the fixing ring 303. At this time, the spring 306 is stretched and the guide surface 319 at the bottom of the card plate 318 is squeezed through the sliding sleeve 320. At this time, the card plate 318 drives the rotating shaft 316 to rotate. Under the torsion of the torsion spring 317, the card plate 318 pushes the fixing ring 303 When the connecting sleeve 304 moves, the first supporting ring 308 is driven to move, the first supporting ring 308 drives the first hemisphere 309 to move, and the first hemisphere 309 drives the lifting block 322 to slide upward along the inner wall of the lifting groove 321 until the top of the first hemisphere 309 contacts the bottom of the second hemisphere 313. At this time, the first hemisphere 309 and the second hemisphere 313 are combined to form a complete sphere, the top of the first supporting ring 308 contacts the second supporting ring 311, and the first supporting ring 308 and the second supporting ring 311 limit the sphere;

[0065] The motor 102 is started, so that the punch 401 continues to move downward and is blocked by the stone. At this time, the rod 310 drives the first hemisphere 309 and the second hemisphere 313 to rotate, so that the rod 310 is tilted, and the roller 408 rolls along the outer wall of the stone to adjust the moving direction of the punch 401, so as to quickly get rid of the blockage of the stone;

[0066] By pressing the clamping plate 318, the clamping plate 318 is disengaged from the fixing of the sliding sleeve 320. At this time, under the elastic force of the spring 306, the sliding sleeve 320 drives the connecting sleeve 304 to slide downward, and the connecting sleeve 304 drives the first supporting ring 308 to move downward. At this time, the first hemisphere 309 drives the lifting block 322 to slide downward along the lifting slot 321, and the insertion rod 310 moves vertically downward.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
