Description

Technical Field

[0001] This invention relates to the field of agricultural tillage and fertilization technology, specifically a handheld agricultural tillage and fertilization device for small terrain. Background Technology

[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide them with the necessary nutrients and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil, and enhance economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development.

[0003] To make fertilization easier, handheld fertilizer applicators are used. For example, application number CN202010982991.3 discloses a fertilizer applicator whose key technical features include a fertilizer box with a feeding port at the center of the top. A top cover is threaded onto the feeding port, and a boss is provided at the bottom of the top cover. The outer wall of the boss is covered with a sealing gasket. Handle latches are provided on the top of the fertilizer box and on both sides of the feeding port. A shoulder strap is connected to each of the two handle latches. The bottom of the fertilizer box... The fertilizer box is equipped with a discharge port and a feeding pipe. An air exchange box is installed at the bottom of the right side wall of the fertilizer box, and air holes are provided on the air exchange box. The advantages of this patent are that it can reduce labor intensity. When using powdered fertilizer, it can prevent the material inside the fertilizer box from becoming stuck and bulging. It has the function of buffering fertilizer, preventing bulging, and allows fertilizer to be put into the pipe in a measured amount, which saves fertilizer. It can easily break up the soil to reach the crop roots, reduce soil compaction, and improve fertilizer utilization.

[0004] The design of the fertilizer applicator in this patented technology has the following problems: First, when the fertilizer applicator is inserted into the soil for fertilizer application, the soil at the bottom deforms under the pressure and is squeezed into the fertilizer applicator. This squeezing phenomenon is more pronounced, especially when the soil is moist or highly compacted. The soil squeezed into the fertilizer applicator hinders the smooth flow of fertilizer, resulting in unstable fertilizer discharge and affecting the uniformity and consistency of fertilization. At the same time, the soil entering the fertilizer applicator fills the pipe space, increasing the resistance inside the fertilizer applicator. This requires greater pressure for fertilizer discharge, increasing the workload of the fertilizer applicator and reducing its efficiency. Second, due to the adhesive nature of soil, when the fertilizer applicator is inserted into the soil, soil particles adhere to the inner wall of the pipe, forming a viscous soil layer. When the fertilizer is discharged, the fertilizer cannot carry the soil adhering to the pipe wall with it. As fertilization continues, this soil layer gradually thickens, eventually clogging the fertilizer applicator and affecting its normal operation. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This handheld agricultural tillage and fertilization device for small terrain is equipped with a fertilization device component assembly. Before fertilization, the fertilizer tube is connected to one end of the upper pipe fitting. The fertilizer backpack is then worn on the operator's back. When entering the farmland for fertilization, the operator holds the handle and controls the shovel to align with the desired fertilization location. After inserting the shovel into the soil, the fingers holding the handle can pull the handle. Pulling the handle in the direction of the handle stretches the tension spring at the bottom of the handle. This movement of the handle rotates the upper sealing valve body, releasing the seal on the middle pipe fitting. Fertilizer then enters the upper pipe fitting through the fertilizer tube, and subsequently passes through the upper pipe fitting, middle pipe fitting, and upper sealing valve body. The fertilizer entering the lower sealing valve body will accumulate inside the metering tube. The operator can check the amount of fertilizer inside the handle through the transparent strip on the side, which is marked with graduations. This design facilitates control of the fertilizer release amount each time. After adjusting to the appropriate amount of fertilizer, releasing the handle will cause the spring at the bottom of the handle to pull it back to its original position. At this point, the upper sealing valve body will reseal the middle tube to prevent fertilizer from entering the metering tube. Then, the foot pedal is pressed, causing it to move downwards. The pedal will move the frame plate and vertical rod downwards together, and the movement of the vertical rod will cause the vertical rod to move downwards. The piston moves downwards within the oil pipe, and the hydraulic oil inside flows from the bottom of the oil pipe into the distributor. The distributor then distributes the hydraulic oil to the horizontal oil pipe. The push rod moves within the horizontal oil pipe, and through the support plate, it pushes open the shovel body. At this point, the shovel body opens from its sealed state around the fertilizer outlet, widening the soil on both sides and exposing the fertilizer outlet. As the frame plate moves, it drives the toothed mechanism downwards, pushing open the pawl body. However, the pawl body, through a rear rod and tension spring on one side, is pushed open by the toothed mechanism and then pulled back by the tension spring. This operation drives the lower sealing valve body connected to the pawl body. At this time, the fertilizer stored in the handle passes through the lower sealing valve body and enters the lower pipe. Subsequently... The fertilizer is discharged through the discharge port at the bottom of the lower pipe. After discharge, the fertilizer passes through the open shovel body and comes into contact with the soil. Then, the entire fertilization structure is pulled out from the diagram. Subsequently, due to the oil pressure in the horizontal oil pipe, the shovel body will close again after the pedal is released. During the closing process, it will drive the various structures in the fertilizer dispensing assembly to reset. After resetting, the next fertilization can be carried out. Compared with the existing technology, which directly inserts the fertilizer discharge port into the soil, the structure of this fertilization device assembly can block the soil through the presence of the shovel body. The soil cannot come into contact with the fertilizer discharge port structure, and the shovel body can ensure that the fertilizer enters the soil through opening and closing, avoiding soil blockage of the fertilizer discharge port position. This can ensure the efficiency of fertilizer discharge from the fertilizer discharge port during long-term operation.

[0017] 2. This handheld agricultural tillage and fertilization device for small terrain is equipped with an impact auxiliary component group. The impact auxiliary component group is designed to pull the pull rod and the horizontal toothed component upwards. During the upward movement of the horizontal toothed component and the pull rod, the pawl body two is pushed open. Due to the side plate and tension spring on one side of the pawl body two, the pawl body two continuously resets. Through the contact between the pawl body two and the horizontal toothed component, the horizontal toothed component and the pull rod can only rise and cannot descend. Pulling the pull rod upwards will drive the moving rod upwards, the main tension spring will be pulled and extended, and the hammer head will also be pulled upwards. When it is necessary to insert the shovel into the soil, by pulling the small... The rod and stop block release the lock on the second pawl. At this time, the second pawl cannot lock the horizontal tooth and the pull rod downwards. The main tension spring will release its stored force and strike the hammer head onto the impact head. By striking the impact head, the operator is assisted in inserting the shovel into the soil. This impact assist component group is designed to allow for faster insertion into the soil, especially when facing relatively hard soil. The pulling of the pull rod and the horizontal tooth, along with the overall design of the impact assist component group, ensures that the pulling force is stored. After storage, the force is released, and the shovel can be directly driven into the soil. This design can effectively improve the efficiency of the fertilizer applicator in inserting into the soil.

[0045] Working principle: Before fertilization, connect the fertilizer tube to one end of the upper fitting 111. Then, wear the fertilizer backpack on your back. When entering the farmland to fertilize, the operator holds the handle 131 and controls the shovel 129 to be aligned with the desired fertilization location. After inserting the shovel 129 into the fertilization soil, the fingers holding the handle 131 can pull the handle 133. Pulling the handle 133 towards the handle 131 will stretch the tension spring at the bottom of the handle 133. By moving the handle 133, the handle 133 will move... Rotating the upper sealing valve body 134 releases the seal on the middle fitting 112, allowing fertilizer to enter the upper fitting 111 through the fertilizer application pipe. It then passes through the upper fitting 111, the middle fitting 112, and the upper sealing valve body 134 before entering the lower sealing valve body 139. The fertilizer in the lower sealing valve body 139 accumulates inside the metering fitting 113. The operator can check the amount of fertilizer inside the handle 133 through the transparent strip 135 on the side, which displays the amount via graduations. The design allows for easy control of the fertilizer release amount each time. Once the appropriate fertilizer amount is adjusted, releasing the handle 133 will cause the tension spring at the bottom of the handle 133 to pull it back to its original position. At this point, the upper sealing valve body 134 will re-seal the middle tube 112, preventing fertilizer from continuing to enter the metering tube 113. Then, pressing the pedal 121 will move it downwards, causing the frame plate 122 and the vertical rod 123 to move downwards together. The movement of the vertical rod 123 will cause one end of the vertical rod 123 to connect... The piston moves downward within the oil pipe body 124. The hydraulic oil inside the oil pipe body 124 flows from the bottom of the oil pipe body 124 into the distributor 125, and then the distributor 125 distributes the hydraulic oil to the horizontal oil pipe 126. The push rod 127 moves within the horizontal oil pipe 126, and the push rod 127 pushes open the shovel body 129 via the support plate 128. At this time, the shovel body 129 opens from its sealed state surrounding the fertilizer outlet 115, widening the soil on both sides and exposing the fertilizer outlet 115. Furthermore, as the frame plate 122 moves, it drives the tooth conditioner 136...When the tooth condition 136 moves downward, it will push open the pawl body 137. However, the pawl body 137, through the back rod 138 on one side and the tension spring, will be pushed open again by the tooth condition 136 and then pulled back by the tension spring. This operation will drive the lower sealing valve body 139 connected to the pawl body 137. At this time, the fertilizer stored in the handle 133 will pass through the lower sealing valve body 139 and enter the lower pipe 114. Then it will be discharged through the fertilizer outlet 115 at the bottom of the lower pipe 114. The discharged fertilizer will pass through the opened shovel body 129 and come into contact with the soil. After that, the entire fertilization structure is pulled out from the figure. Subsequently, due to the oil pressure in the horizontal oil pipe 126, After releasing the pedal 121, the shovel 129 will close again. During the closing process, it will reset the various structures in the fertilizer dispensing assembly 12. After the reset, the next fertilization can be carried out. Compared with the prior art, which directly inserts the fertilizer dispensing port 115 into the soil, the structure of this fertilizer dispensing device assembly 01 can block the soil through the presence of the shovel 129. The soil cannot interact with the structure of the fertilizer dispensing port 115, and the shovel 129 can ensure that fertilizer enters the soil by opening and closing, avoiding soil blockage of the fertilizer dispensing port 115. This ensures the efficiency of fertilizer dispensing from the fertilizer dispensing port 115 during long-term operation. In the corresponding impact auxiliary component group 02, the pull rod 21 and the transverse tooth 22 can be pulled upwards. During the upward movement of the transverse tooth 22 and the pull rod 21, the pawl body 23 will be pushed open. Due to the side plate 24 on one side of the pawl body 23 and the tension spring on the side plate 24, the pawl body 23 will continuously reset. Through the contact between the pawl body 23 and the transverse tooth 22, the transverse tooth 22 and the pull rod 21 can only rise and cannot fall. Pulling the pull rod 21 upwards will drive the moving rod 28 to pull upwards, the main tension spring 29 will be pulled and extended, and the hammer head 211 will also be pulled upwards. When it is necessary to insert the shovel body 129 into the soil, the small rod 27 and the stop block 26 are pulled to release the obstruction. When the pawl body 23 is locked, it cannot lock the horizontal toothed member 22 and the pull rod 21 downwards. The main tension spring 29 releases its stored force, causing the hammer head 211 to strike the impact head 212. This strike assists the operator in inserting the shovel body 129 into the soil. This impact assist component group 02 design allows for faster insertion into harder soil. The pulling action of the pull rod 21 and the horizontal toothed member 22, along with the overall design of the impact assist component group 02, ensures the storage of pulling force. After storage, the force is released, directly driving the shovel body 129 into the soil. This design effectively improves the efficiency of the fertilizer applicator's insertion into the soil.
