Description

Technical Field

[0001] The invention relates to the technical field of tomato fertilization machinery, in particular to a quantitative fertilization device and method for tomato planting root systems. Background Art

[0002] As an important economic crop, tomatoes have strict requirements for fertilization management during their planting process. Reasonable fertilization methods can effectively promote the development of tomato roots, increase plant growth rate, and improve fruit yield and quality. Traditional fertilization methods are usually based on manual spreading. Although the operation is simple, there are problems such as uneven fertilization, serious waste, and low fertilizer absorption efficiency. Therefore, with the development of agricultural mechanization, fertilization devices dedicated to tomato planting have been widely used.

[0003] Currently, the tomato fertilizer application devices on the market usually achieve automated fertilization through mechanical mechanisms. Their principles are mostly based on rotary spreading, pneumatic drive or gravity flow. These devices can quickly complete large-area fertilization operations and avoid the unevenness problems caused by manual operation.

[0004] Although the existing tomato fertilization device has made significant progress in fertilization efficiency and ease of operation, it still has many shortcomings. First, the existing devices mostly use fixed fertilization positions, lack dynamic adaptability to the growth status of tomato plants, and easily cause fertilizer waste or insufficient fertilization of some plants; secondly, after fertilization with the existing device, the fertilized area needs to be sprayed manually, thereby increasing the workload of employees. In addition, during the long-term use of the existing device, since a fertilization channel needs to be left in the discharge port area, moisture is easy to enter and cause the fertilizer particles to become damp and clump. Summary of the invention

[0019] The present invention also provides a method for using a quantitative fertilization device for tomato planting roots, comprising the following steps:

[0020] Step 1: When in use, move the tractor and move the frame to between two tomato plants, and the wheels are located in the walkway on the opposite side of the two tomato plants. At this time, the frame is moved to a position close to any tomato plant or between two tomato plants through the guide rails to change the position of subsequent fertilization according to the fertilization needs of the two tomato plants;

[0021] Step 2: The metering sleeve is moved downward by driving the cylinder, so that the flap 2 contacts the soil.

At the same time, under the action of the fertilizer pit, most of the medicine energy can be dispersed to the surroundings, so that the medicine energy can act on the root system of tomatoes. By driving the motor and under the action of the synchronous belt one, the three synchronous wheels 1 can rotate at the same time. At the same time, under the action of the two gears and the synchronous belt two, the two synchronous wheels 2 can rotate in the opposite direction of the synchronous wheel 1 at the same time, so that the swing arm drives the fixed water pipe to swing, so as to increase the watering area.

[0024] The present invention provides a device and method for quantitative fertilization of tomato planting roots, which has the following beneficial effects:

[0025] 1. The present invention can dynamically adjust the fertilization position according to the growth status of tomatoes through the displacement mechanism, cooperate with the fertilization mechanism to ensure the accuracy of each fertilization amount, avoid fertilizer waste, improve fertilizer utilization efficiency, and realize directional nutrition supply to the root system.

[0026] 2.

The design of the displacement mechanism 10 improves the flexibility and accuracy of fertilization. The fertilization area can be dynamically adjusted according to the growth status of the plants to ensure that the fertilizer is fully utilized and avoid waste or environmental pollution caused by excessive fertilization.

[0041] The fertilization mechanism 20 is arranged in the middle of the displacement mechanism 10, and is used to squeeze the soil, compact the soil and form a fertilization pit, and squeeze and close the fertilization channel, so as to fix the amount of fertilizer applied each time, and open the fertilization channel during the lifting process to complete the fertilization. The design of the fertilization mechanism 20 not only ensures the accuracy of each fertilization through the soil, but also optimizes the soil environment around the root system through the physical compaction of the soil, improves the absorption effect of the fertilizer, and reduces the loss of fertilizer;

[0042] The watering mechanism 30 is arranged on the upper side of the displacement mechanism 10 and is used to perform watering operation on the fertilization area after fertilization. The combined design of the watering mechanism 30 enables irrigation immediately after fertilization, which not only saves labor but also improves the fertilization efficiency and the absorption effect of the fertilizer, and further promotes the rapid growth of the tomato root system;

[0043] The swing mechanism 40 is arranged on the outside of the sprinkler mechanism 30, and is used to control the swing of the sprinkler area so that the sprinkler area can cover two tomato plants. The sprinkler coverage range is increased under the action of the swing mechanism 40, so that the two tomato plants can be evenly moistened, further optimizing the utilization rate of the fertilizer and reducing the waste of water resources.

[0044] Please refer to the attached Figure 1 -Attached Figure 3 In a preferred embodiment of the present invention, the displacement mechanism 10 includes a tractor 101, a connecting rod 102 is fixedly connected to the rear side of the tractor 101, a connecting rod 103 is rotatably connected to the other side of the connecting rod 102, and a frame 104 is fixedly connected to the other side of the connecting rod 103. Through the combined design of the tractor 101, the connecting rod 102 and the connecting rod 103, the frame 104 can run smoothly under different terrain conditions, improve the adaptability of the operation, and reduce the impact on the field operation efficiency. The upper side of the frame 104 is fixedly connected to a guide rail 105, and a fertilizer storage box 106 is arranged between the guide rail 105 and the frame 104 to store fertilizer. Two sliders 107 are fixedly connected to the outside of the box 106, and the two sliders 107 are slidably connected to the side close to the frame 104 and the slider 107 respectively. A cover plate 108 is fixedly connected to the upper side of the fertilizer storage box 106, and a flap 109 is rotatably connected to the middle part of the cover plate 108. The fertilizer storage box 106 is used to store fertilizer particles. With the cooperation of the cover plate 108 and the flap 109, the closure of the fertilizer storage box 106 can be ensured, and space for fertilizer particles to enter can be provided. The position of the fertilizer storage box 106 can be adjusted with the cooperation of the guide rail 105 and the slider 107, so that the fertilizer storage box 106 can be flexibly adjusted according to the growth status of the tomato plants to achieve precise fertilization.

[0045] Please refer to the attached Figure 1 -Attached Figure 7In a preferred embodiment of the present invention, the fertilizing mechanism 20 includes a mounting frame 201, the mounting frame 201 is fixedly connected to the upper side of the cover plate 108, the bottom of the mounting frame 201 is fixedly connected to a cylinder 202, the stability design of the mounting frame 201 provides a solid support for the cylinder 202, and avoids the problem of unstable fertilization amount or device wear caused by the cylinder 202 falling off, and the output end of the cylinder 202 is fixedly connected to a support rod 203, the outer side of the support rod 203 is fixedly connected to a quantitative sleeve 204, the outer side of the quantitative sleeve 204 is fixedly connected to two groups of fixed blocks 205, and an I-shaped rod 207 is fixedly connected between the two groups of fixed blocks 205, and the I-shaped rod 207 is fixedly connected to the I-shaped rod 207. A clockwork spring 206 is fixedly connected between the fixed block 205 and the I-shaped rod 207, a rotating plate 208 is fixedly connected to the outer periphery of the I-shaped rod 207, two limit blocks 209 are slidably connected to the middle of the rotating plate 208, a T-shaped block 210 is rotatably connected between the two limit blocks 209, a baffle 211 is fixedly connected to the side of the T-shaped block 210 close to the quantitative sleeve 204, the baffle 211 is slidably connected to the middle of the quantitative sleeve 204, an anti-slip block 212 is fixedly connected to the top of the baffle 211, the anti-slip block 212 is in contact with the quantitative sleeve 204, a connecting block 213 is fixedly connected to the bottom of the quantitative sleeve 204, and a flap 214 is rotatably connected to the middle of the connecting block 213;

[0046] Specifically: by driving the cylinder 202, the support rod 203 drives the metering sleeve 204 to move downward, at which time the flap 214 can contact the soil and close under the pressure of the soil, forming a fertilizer pit in the process of continuous downward pressure, and when the rotating plate 208 contacts the inner wall of the fertilizer pit, it will be squeezed, so that the I-shaped rod 207 twists and compresses the clockwork spring 206, and at this time, the rotating plate 208 is rotated and the T-shaped block 210 is made to slide in the rotating plate 208 under the limit provided by the T-shaped block 210 and the limit block 209, so that the T-shaped block 210 always remains parallel to the baffle 211, so that when the rotating plate 208 rotates, the baffle 211 can be driven to move by the T-shaped block 210, and the two baffles 211 are in contact at the same time. The operation of closing the fertilization channel in the metering sleeve 204 is that when the metering sleeve 204 enters the fertilizer storage box 106, the fertilizer particles roll into it, thereby completing the quantitative operation before each fertilization under the obstruction of the baffle 211. At this time, the driving cylinder 202 moves the metering sleeve 204 upward. First, the metering sleeve 204 filled with fertilizer particles extends out of the fertilizer storage box 106, and then the rotating plate 208 is separated from the fertilization pit, and during the separation process, the rotating plate 208 is driven by the clockwork spring 206 to expand outward, so that the baffle 211 is opened and the fertilizer particles fall. The impact force generated during the initial fall can loosen and shake off the soil at the bottom of the flap 214, and then the flap 214 is squeezed open by the weight of the fertilizer particles, thereby completing the quantitative fertilization operation.

[0047] Please refer to the attached Figure 8In a preferred embodiment of the present invention, the watering mechanism 30 includes a water tank 301, which is fixedly connected to the upper side of the frame 104, and a sunshade 302 is rotatably connected to the upper side of the water tank 301.

A nozzle 307 is fixedly connected, and water pump 303 can be driven to pump water. At the same time, the filter cartridge 304 prevents solid impurities in the water from entering the water pump 303, thereby reducing the wear of the water pump 303 and increasing the service life of the water pump 303. At the same time, with the cooperation of the connecting pipe 305 and the fixed water pipe 306, water can be delivered to the nozzle 307, and the nozzle 307 disperses the water and sprays it evenly to avoid local water accumulation. At the same time, with the cooperation of the fertilizer pit and the compacted soil, most of the medicine power can be brought close to the two tomatoes, thereby completing the fertilization operation of the tomato root system.

[0048] Please refer to the attached Figure 8 and attached Fig. 9 In a preferred embodiment of the present invention, the swing mechanism 40 includes a dust cover 401, which is fixedly connected to the outside of the water tank 301, and a shell 403 is fixedly connected to the outside of the dust cover 401. The dust cover 401 and the shell 403 provide support for the entire swing mechanism 40, thereby preventing the swing mechanism 40 from falling off. The inside of the shell 403 is rotatably connected to multiple sets of synchronous wheels 404, and the outer periphery of the multiple sets of synchronous wheels 404 is provided with a synchronous belt 405. The inside of the dust cover 401 is fixedly connected to a motor 402, and one of the synchronous wheels 404 is fixedly connected to the motor 402. At the output end of 402, the internal rotation of the shell 403 is connected to two gears 406, one of which is fixedly connected to one end of one of the synchronous wheels 404 away from the motor 402, and the internal rotation of the shell 403 is connected to two synchronous wheels 407, one of which is fixedly connected to one of the gears 406, and one of the synchronous wheels 407, one of the gears 406 and one of the two synchronous wheels 404 away from the motor 402 are all fixedly connected to a swing arm 409, and the connecting pipe 305 and the fixed water pipe 306 are connected via the swing arm 409.

[0049] Specifically: a power transmission mechanism is provided by the cooperation of multiple sets of synchronous wheels 404 and synchronous belts 405, which can drive the remaining synchronous wheels 404 to rotate simultaneously when one synchronous wheel 404 rotates. The motor 402 is used to provide a driving source, so that one of the motors 402 can rotate, and when rotating, half of the swing arm 409 can be tilted to one side, and when the synchronous wheel 404 rotates, the rotation can be reversed by the cooperation of two gears 406, and the other half of the swing arm 409 can be moved to the other side by the cooperation of synchronous wheel 2 407 and synchronous belt 2 408, thereby expanding the spraying range, and at the same time, after exceeding two tomato plants, the motor 402 is driven in reverse to move the multiple sets of swing arms 409 between the two tomato plants, thereby completing the swing of the spraying area and improving the uniformity of watering and irrigation efficiency.

[0050] Please refer to the attached Figure 3 In a preferred embodiment of the present invention, two hollow plates 5 are fixedly connected to the inside of the fertilizer storage box 106, and a heating element 6 is fixedly connected to the middle of the hollow plate 5. The hollow plate 5 can make the fertilizer particles roll into the falling quantitative sleeve 204, and at the same time provide a space for the placement of the heating element 6. The heating element 6 is used to provide thermal energy, thereby heating the fertilizer on the upper side of the hollow plate 5 to prevent moisture in the soil and air from entering and causing the fertilizer particles to be damaged by moisture or unable to roll into the fertilization channel of the quantitative sleeve 204, so that the fertilization mechanism 20 can stably perform fertilization work.

[0051] Please refer to the attached Figure 6 In a preferred embodiment of the present invention, two limiting grooves 7 are provided in the middle of the rotating plate 208, and the limiting block 209 is slidably connected to the middle of the limiting groove 7. The limiting groove 7 limits the rotating plate 208, so that the rotating plate 208 can only move in parallel, thereby avoiding the problem of the T-shaped block 210 falling off, and enabling the baffle 211 to stably close the fertilization channel of the quantitative sleeve 204.

[0052] Please refer to the attached Figure 7 In a preferred embodiment of the present invention, a compression spring 215 is fixedly connected to the inside of the baffle 211, and a rubber pad 216 is fixedly connected to the other end of the compression spring 215. The two rubber pads 216 are in contact with each other. The elastic force of the compression spring 215 can make the rubber pad 216 always protrude. At the same time, when the two rubber pads 216 are in contact with each other, the rubber pads 216 can be squeezed and deformed, thereby increasing the sealing performance of the metering sleeve 204, preventing moisture and humidity in the soil from entering the fertilizer storage box 106, thereby increasing the storage time of the fertilizer particles.

[0053] Please refer to the attached Figure 4 and attached Figure 5In a preferred embodiment of the present invention, an arc is provided at the bottom of the second flap 214, and the arc is used to close the second flap 214 when it contacts the soil to avoid soil entry and blockage. The arc can make it easier for the soil to squeeze the second flap 214 and flip it closed when the second flap 214 contacts the soil, thereby greatly reducing the entry of soil, so that the impact and weight of the subsequent fertilizer particles will make the incoming soil fall.

[0054] The present invention also provides a method for using a quantitative fertilization device for tomato planting roots, comprising the following steps:

[0055] Step 1: When in use, the tractor 101 is moved and the frame 104 is moved between two tomato plants, and the wheels are located in the walkway on the opposite side of the two tomato plants. At this time, the frame 104 is moved to a position close to any tomato plant or between two tomato plants through the guide rail 105, so as to change the position of subsequent fertilization according to the fertilization needs of the two tomato plants;

[0056] Step 2: The quantitative sleeve 204 is moved downward by driving the cylinder 202, so that the second flap 214 contacts the soil. When in contact, the soil can close the second flap 214, and a fertilizer pit is generated in the soil after closing. When continuing to move downward, the rotating plate 208 contacts the inner wall of the fertilizer pit, so that the rotating plate 208 can drive the I-shaped rod 207 to rotate and twist and compress the spring spring 206. At this time, the folding operation of the rotating plate 208 is completed. During the folding process, the baffle plate 211 and the T-shaped block 210 are limited to make the limit block 209 slide downward and rotate in the rotating plate 208, thereby pushing the two baffle plates 211 to approach each other, thereby closing the quantitative sleeve 204. At the same time, the quantitative sleeve 204 moves into the fertilizer storage box 106. At this time, the fertilizer particles fall into the quantitative sleeve 204 until it is full, thereby completing the quantitative operation of fertilization;

[0057] Step 3: After the quantitative measurement is completed, the quantitative sleeve 204 is raised by driving the cylinder 202. At this time, the quantitative sleeve 204 is opened first. If it cannot be opened due to the accumulation of soil, the soil can be shaken off by the gravity of the subsequent fertilizer particles and the vibration generated by the impact, so that the quantitative sleeve 204 is opened. When the rotating plate 208 moves out of the fertilizer pit, the spring spring 206 can unfold the rotating plate 208, so that the T-shaped block 210 pulls the baffle 211 to separate the two baffles 211, and the baffle 211 is prevented from falling off by the anti-falling block 212, thereby completing the fertilization operation;

[0058] Step 4: After fertilization, the water is driven by the water pump 303 to pass through the filter cartridge 304, the connecting pipe 305 and the fixed water pipe 306 in sequence and then sprayed out through the nozzle 307. At the same time, under the action of the fertilizer pit, most of the medicine energy can be dispersed to the surroundings, so that the medicine energy can act on the root system of tomatoes.

10. A method for using a quantitative fertilization device for tomato planting roots, characterized in that: The method of using the tomato planting root quantitative fertilization device according to any one of claims 1 to 9 comprises the following steps: Step 1: When in use, the tractor (101) is moved and the frame (104) is moved between two tomato plants, and the wheels are located in the walkway on the side opposite to the two tomato plants. At this time, the frame (104) is moved to a position close to any tomato plant or between two tomato plants through the guide rail (105), so as to change the position of subsequent fertilization according to the fertilization needs of the two tomato plants; Step 2: The metering sleeve (204) is moved downward by driving the air cylinder (202), so that the second flap (214) contacts the soil. When in contact, the soil can close the second flap (214), and after closing, a fertilizer pit is formed in the soil. When the rotating plate (208) continues to move downward, it contacts the inner wall of the fertilizer pit, so that the rotating plate (208) can drive the I-shaped rod (207) to rotate and twist and compress the spring (206). At this time, the rotating plate (208) is completed. ) during the folding process, the limit block (209) is caused to slide downward and rotate in the rotating plate (208) through the limit of the baffle plate (211) and the T-shaped block (210), thereby pushing the two baffle plates (211) closer to each other, thereby closing the quantitative sleeve (204), and at the same time, the quantitative sleeve (204) is moved into the fertilizer storage box (106), and the fertilizer particles fall into the quantitative sleeve (204) until it is full, thereby completing the quantitative operation of fertilization; Step 3: After the quantitative amount is completed, the quantitative sleeve (204) is raised by driving the air cylinder (202). At this time, the quantitative sleeve (204) is opened first. If it cannot be opened due to the accumulation of soil, the soil can be shaken off by the gravity of the subsequent fertilizer particles and the vibration generated when hitting, so that the quantitative sleeve (204) is opened. When the rotating plate (208) moves out of the fertilizer pit, the spring (206) can unfold the rotating plate (208), so that the T-shaped block (210) pulls the baffle (211) to separate the two baffles (211), and the baffle (211) is prevented from falling off by the anti-falling block (212), thereby completing the fertilization operation; Step 4: After fertilization, the water is driven by the water pump (303) to pass through the filter cartridge (304), the connecting pipe (305) and the fixed water pipe (306) in sequence and then sprayed out through the nozzle (307). At the same time, under the action of the fertilizer pit, most of the medicine energy can be dispersed to the surroundings, so that the medicine energy can act on the root system of the tomato. By driving the motor (402) and under the action of the synchronous belt one (405), the three synchronous wheels one (404) can be rotated at the same time. At the same time, under the action of the two gears (406) and the synchronous belt two (408), the two synchronous wheels two (407) can be rotated in the opposite direction to the synchronous wheel one (404) at the same time, so that the swing arm (409) drives the fixed water pipe (306) to swing, so as to increase the area of ​​watering.
