Description

Technical Field

[0001] The utility model relates to the field of grapes, in particular to the technical field of grape planting, and specifically refers to a fertilizer quantitative release device for grape planting. Background Art

[0002] Grapes are woody vines of the genus Vitis in the family Vitaceae. Their branches are cylindrical, longitudinally ridged, and may be glabrous or covered with sparse, soft hairs. Leaves are oval in shape, and the inflorescence is conical, densely or sparsely distributed, with well-developed basal branches. Fruits vary in shape, ranging from spherical to oval. Grapes typically bloom between April and May, while ripening occurs between August and September. Fertilization is a key step in grape cultivation. Fertilizers are typically mixed before application.

[0003] In grape cultivation, soil quality and fertilizer application efficiency are directly linked to grape growth and yield quality. Traditional fertilization methods rely on manual labor, where different types of fertilizer are mixed and then manually spread across the soil surface. This makes it difficult to ensure uniform fertilizer distribution during spreading, potentially resulting in over- or under-fertilization in certain areas. Furthermore, fertilizer stored for extended periods of time tends to clump, complicating mixing and impacting its effectiveness. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the existing technology and provides a quantitative fertilizer release device for grape planting, which can deliver fertilizer to the soil at a fixed point and in a fixed quantity, thus avoiding uneven spreading caused by fertilization. At the same time, the fertilizer is mixed into the liquid to avoid agglomeration of the fertilizer due to long-term storage.

[0005] The utility model is realized through the following technical scheme: a quantitative release device for fertilizer for grape planting, comprising a charging tank filled with fertilizer liquid, a release tube connected to the discharge port of the charging tank and inserted into the soil, and a plurality of discharge holes on the circumferential surface of the release tube, wherein a pressure valve is provided in the discharge hole, a downward sealing sliding pressure plate is further provided in the charging tank, and a driving device for driving the pressure plate to move a fixed length is further provided on the charging tank.

[0006] When the utility model is in use, the driving device drives the pressure plate to press down a fixed length, thereby pushing the fertilizer liquid out of the pressure valve into the soil. Since the fertilizer liquid drops to a certain height, the volume of the fertilizer liquid flowing out of the pressure valve is certain, thereby realizing quantitative fertilization of the fertilizer liquid. At the same time, the charging tank is placed in a fixed position, thereby realizing fixed-point and quantitative fertilization. Only under the action of pressure can the fertilizer be discharged from the pressure valve, which can prevent the fertilizer from being discharged from the discharge hole under the action of its own gravity, thereby controlling whether the fertilizer is released, thereby ensuring uniform fertilizer sowing, and mixing the fertilizer into the liquid to prevent the fertilizer from caking due to long-term storage.

[0007] Preferably, the driving device includes an electric push rod arranged on the charging tank, the protruding end of the electric push rod extends above the charging tank, and a connecting rod extending above the charging tank and connected to the protruding end of the electric push rod is fixed to the top surface of the pressure plate.

[0008] This preferred solution realizes the fixed-length movement of the driving connecting rod and the pressure plate by setting an electric push rod.

[0009] Preferably, the release tube is provided with a fixed plate located above the discharge hole.

[0010] When using this preferred solution, the fixing plate is placed on the ground, thereby supporting the release pipe and the charging tank.

[0011] Preferably, a long hole extending along the axial direction is provided on the circumferential surface of the charging tank, and a transparent plate with scales is sealedly connected in the long hole.

[0012] The preferred solution facilitates observation of the amount of fertilizer liquid in the charging tank through the scale by providing a transparent plate.

[0013] Preferably, the release tube is further provided with a first electronic valve, and the release tube is further provided with a plurality of discharge holes located below the discharge hole.

[0014] When this preferred solution is in use, when the pressure plate moves to the inner bottom surface of the charging tank, some fertilizer liquid remains in the release tube. Since the pressure plate cannot continue to move downward at this time, the discharge hole is provided to facilitate this part of the fertilizer liquid to flow out of the release tube. At the same time, when fertilization is not in progress, the first electronic valve is driven to close to prevent the fertilizer liquid from flowing out of the discharge hole.

[0015] Preferably, the pressure plate includes a pressure plate and a rubber ring arranged on the circumferential surface of the pressure plate, the rubber ring is inclined from the inside to the outside, the inner ring of the rubber ring is located above the outer ring, and the outer diameter of the rubber ring is larger than the inner diameter of the charging tank.

[0016] This preferred solution is to set the rubber ring. When the pressure plate moves downward and presses the fertilizer liquid, the rubber ring is deformed by the pressure of the fertilizer liquid, and the outer ring of the rubber ring will move upward, thereby increasing the outer diameter of the rubber ring and enhancing the sealing effect between the rubber ring and the inner cavity of the charging tank, thereby facilitating the discharge of the fertilizer liquid from the discharge hole; when the pressure plate moves upward, the first electronic valve is closed, and negative pressure is formed under the pressure plate. At the same time, the air above the pressure plate is squeezed, so that part of the air above the pressure plate flows downward and squeezes the rubber ring. This part of the air squeezes the outer ring of the rubber ring inward, causing the rubber ring to deform, and a gap is formed between the rubber ring and the charging tank, so that the air above the pressure plate enters under the pressure plate, thereby avoiding the formation of negative pressure in the charging tank; when the first electronic valve is not closed or the pressure plate seal is slidably connected in the charging tank, during the upward movement of the pressure plate, air enters the release pipe and the charging tank from the discharge hole, but this part of the air will drive soil to block the discharge hole or enter the release pipe and the charging tank.

[0017] Preferably, the charging tank is provided with two feeding ports, the arrangement direction of the two feeding ports is the same as the arrangement direction of the plurality of charging tanks, and a second electronic valve is provided on the feeding port.

[0018] When this preferred solution is in use, a feed pipe is provided between two adjacent charging tanks, and the two ends of the feed pipe are respectively connected to the two feed ports on the two charging tanks. When one charging tank is filled with fertilizer liquid, the fertilizer liquid will enter the feed pipe, thereby filling the other charging tank, and so on, thereby facilitating the feeding of multiple charging tanks.

[0019] Preferably, a conical drill bit is fixed to the bottom surface of the release tube. When in use, the drill bit facilitates the release tube to be quickly inserted into the soil.

[0020] The beneficial effects of the utility model are as follows: the driving device drives the pressure plate to press down a certain length, thereby pushing the fertilizer liquid out of the pressure valve into the soil. Since the fertilizer liquid drops to a certain height, the volume of the fertilizer liquid flowing out of the pressure valve is certain, thereby realizing quantitative fertilization of the fertilizer liquid. At the same time, the charging tank is placed in a fixed position, thereby realizing fixed-point and quantitative fertilization. Only under the action of pressure can the fertilizer be discharged from the pressure valve, which can prevent the fertilizer from being discharged from the discharge hole under the action of its own gravity, thereby controlling the fertilizer to be discharged. Whether to release, thereby ensuring uniform fertilizer spreading, and at the same time mixing the fertilizer into the liquid to avoid fertilizer agglomeration due to long-term storage; through the setting of the electric push rod, the connecting rod and the pressure plate are driven to move at a fixed length; when the pressure plate moves to the inner bottom surface of the charging tank, some fertilizer liquid remains in the release tube. Since the pressure plate cannot continue to move downward at this time, the setting of the discharge hole facilitates this part of the fertilizer liquid to flow out of the release tube. At the same time, when no fertilization is carried out, the first electronic valve is driven to close to prevent the fertilizer liquid from flowing out of the discharge hole.

[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0028] Refer to the attached Figure 1-4 The utility model is a quantitative release device for fertilizer for grape planting, comprising a charging tank 1, a discharge port being provided at the bottom end of the charging tank 1, two oppositely arranged feed ports 10 being provided on the circumferential surface of the charging tank 1, the arrangement direction of the two feed ports 10 being the same as the arrangement direction of the plurality of charging tanks 1, a feed pipe being further provided between two adjacent charging tanks 1, one end of the feed pipe being communicated with the feed port 10 of one charging tank 1, and the other end of the feed pipe being communicated with the feed port 10 of the other charging tank 1, and a first electronic valve 4 being further provided on the feed port 10.

[0029] A long hole extending along its axial direction is also provided on the circumferential surface of the charging tank 1, and a transparent plate 12 with a scale is sealed in the long hole. A pressure plate 9 is also provided in the charging tank 1, and the pressure plate 9 includes a pressure plate and a rubber ring arranged on the circumferential surface of the pressure plate. The rubber ring is inclined from the inside to the outside, and the inner ring of the rubber ring is located above the outer ring. The outer diameter of the rubber ring is larger than the inner diameter of the charging tank 1, that is, the rubber ring is squeezed on the inner circumferential surface of the charging tank 1, thereby realizing a sealed connection between the pressure plate 9 and the charging tank 1.

[0030] The top of the pressure plate is fixed with a connecting rod 8 extending upward and passing through the charging tank 1. The connecting rod 8, the pressure plate and the charging tank 1 are arranged coaxially. The outer circumferential surface of the charging tank 1 is also fixed with an electric push rod 7 with the protruding end extending upward. The circumferential surface of the charging tank 1 is fixed with a fixed block 6. The cylinder body of the electric push rod 7 is fixed in the fixed block 6. The protruding end of the electric push rod 7 is connected to the connecting rod 8 through a horizontal plate. The electric push rod 7 forms a driving device that drives the pressure plate 9 to move at a fixed length.

[0031] The discharge port of the charging tank 1 is connected to a release tube 2 inserted into the soil. A conical drill bit is fixed to the bottom surface of the release tube 2, and a fixed disk 13 is fixed to the circumferential surface of the release tube 2. The fixed disk 13 and the release tube 2 are arranged coaxially. The drill bit on the release tube 2 is used to insert multiple release devices into the soil next to multiple grape roots, so that the bottom of the fixed disk 13 is in contact with the soil. The fixed disk 13 can ensure that the release device will not fall over after being inserted into the soil, and can also ensure that the grape roots can be fully in contact with the fertilizer, avoiding the fertilizer being unable to be quickly absorbed by the grape roots due to the release tube 22 being a certain distance away from the grape roots, thereby ensuring the growth of the grapes and product quality.

[0032] A second electronic valve 11 is also provided in the release tube 2 above the fixed disk 13. A plurality of discharge holes are also provided on the circumferential surface of the release tube 2. The discharge holes are connected to the inner cavity of the release tube 2. The discharge holes are located below the fixed disk 13. A one-way pressure valve 5 is provided in the discharge holes. The discharge holes at the same height are evenly arranged along the circumference to form a circumferential hole group, and several circumferential hole groups are arranged along the height direction.

[0033] The release tube 2 is further provided with a discharge hole 3 located below the discharge hole, and the discharge hole 3 is communicated with the inner cavity of the release tube 2 .

[0034] When the utility model is used, several charging tanks 1 are placed at a set position, and then the release pipe 2 is inserted into the soil, and the fixing plate 13 is placed on the ground. Under the action of the fixing plate 13, the charging tanks 1 are supported. Then, several charging tanks 1 are connected in sequence through several feeding pipes;

[0035] When in use, the second electronic valve 11 is closed and the first electronic valve 4 is opened, and the electric push rod 7 is driven to drive the pressure plate 9 to move from top to bottom. When the pressure plate 9 moves downward to press the fertilizer liquid, the rubber ring is deformed by the pressure of the fertilizer liquid, and the outer ring of the rubber ring moves upward, thereby increasing the outer diameter of the rubber ring and enhancing the sealing effect between the rubber ring and the inner cavity of the charging tank 1, thereby pushing the fertilizer liquid into the release pipe 2 and out of the pressure valve 5 into the soil. The length of the contraction of the electric push rod 7 is set to limit the height of the fertilizer liquid descent, so that the volume of the fertilizer liquid flowing out of the pressure valve 5 and the discharge hole 3 is constant, thereby realizing quantitative fertilization of the fertilizer liquid. After the fertilization is completed, the first electronic valve 4 is closed to allow the remaining fertilizer liquid in the release pipe 2 to flow out of the discharge hole 3;

[0036] By analogy, after a certain number of fertilizations, when it is necessary to load the charging tank 1, the first electronic valve 4 is closed, and then the electric push rod 7 is driven to extend, driving the pressure plate 9 to move upward, forming a negative pressure under the pressure plate 9, and at the same time, the air above the pressure plate 9 is squeezed, so that part of the air above the pressure plate 9 flows downward to squeeze the rubber ring, and this part of the air squeezes the outer ring of the rubber ring inward, causing the rubber ring to deform, and a gap is formed between the rubber ring and the charging tank 1, so that the air above the pressure plate 9 enters under the pressure plate 9, thereby avoiding the formation of negative pressure in the charging tank 1;

[0037] When the pressing plate 9 moves to above the feed port 10 , the second electronic valve 11 is opened, and then the fertilizer liquid is fed into the charging tank 1 , and the fertilizer liquid is filled sequentially according to the arrangement order of the charging tanks 1 .
