Description

Technical Field

[0001] This utility model relates to the field of corn planting technology, and in particular to a corn planting topdressing device. Background Technology

[0002] Corn is a common crop in the agricultural planting industry, with a wide planting range. When planting corn, topdressing is usually required. Traditional topdressing equipment is not convenient for adjusting the length of the topdressing pipe according to the position of the corn, which affects the efficiency and effect of topdressing.

[0003] The prior art CN220858898U discloses a topdressing device for corn planting, including a base plate. By tilting the discharge pipe, fertilizer in the topdressing box can flow into the discharge pipe. The corn is topdressed through an extension pipe connected to the discharge pipe. A control valve at the top of the discharge pipe controls the amount of fertilizer flowing out. In the clamping assembly, a compression spring drives a clamping plate to cooperate with a concave support frame to clamp and fix the extension pipe. To adjust the distance between the extension pipe and the discharge pipe, simply pull the limit rod to drive the clamping plate to squeeze the compression spring, causing the clamping plate to disengage from the extension pipe, and then pull the extension pipe to adjust the distance between the extension pipe and the discharge pipe. The output shaft of the drive motor in the stirring assembly drives the rotating rod to rotate. Two sets of stirring plates on the outer wall of the rotating rod fully stir the fertilizer in the topdressing box, ensuring the uniformity of the fertilizer and preventing the fertilizer from clumping and clogging the discharge pipe.

[0004] The device can adjust the distance between the extension tube and the discharge tube, which makes it easier to apply fertilizer to corn at different locations. However, during use, the discharge tube is always in the discharge state and cannot apply fertilizer according to the location of the corn, resulting in serious fertilizer waste and frequent fertilizer replenishment. Utility Model Content

[0005] The purpose of this invention is to provide a topdressing device for corn planting, which solves the problem of an existing topdressing device for corn planting where the discharge pipe is always in the discharge state during use, and cannot apply topdressing according to the position of the corn, resulting in serious fertilizer waste and the need for frequent fertilizer replenishment.

[0006] To achieve the above objectives, this utility model provides a corn planting topdressing device, including a frame and a mixing box, the mixing box being fixedly installed on one side of the frame, and a topdressing assembly; the topdressing assembly includes a moving pipe, a topdressing pipe, a sealing plate, a discharge plate, an elastic member, and a stop bar; the moving pipe is connected to and communicates with the mixing box, and is located on one side of the mixing box; the topdressing pipe is rotatably connected to and communicates with the moving pipe; the sealing plate is fixedly connected to the moving pipe and is located inside the moving pipe; the discharge plate is fixedly connected to the topdressing pipe and is located inside the topdressing pipe; the elastic member is disposed on the discharge plate; and the stop bar is connected to the topdressing pipe and is disposed on the topdressing pipe.

[0007] The movable pipe includes a telescopic pipe and a connecting pipe. The telescopic pipe is connected to and communicates with the mixing box. The connecting pipe is connected to the telescopic pipe, rotatably connected to the topdressing pipe, and fixedly connected to the sealing plate.

[0008] The elastic component includes a rotating shaft and a torsion spring. The rotating shaft is rotatably connected to the sealing plate and fixedly connected to the discharge plate, and is located on one side of the discharge plate. The two ends of the torsion spring are respectively connected to the rotating shaft and the sealing plate, and the torsion spring is sleeved on the rotating shaft.

[0009] The stop lever includes a rod body, a sliding sleeve, and a locking member. The sliding sleeve is slidably connected to the fertilizer pipe and is sleeved on the fertilizer pipe. The rod body is fixedly connected to the sliding sleeve and is located on one side of the sliding sleeve. The locking member is threadedly connected to the sliding sleeve and passes through the sliding sleeve to abut against the fertilizer pipe.

[0010] The corn planting topdressing device also includes a stirring component, which includes a stirring shaft and a stirring rod. The stirring shaft is rotatably connected to the mixing box and is located inside the mixing box. The stirring rod is fixedly connected to the stirring shaft and is mounted on the stirring shaft.

[0011] This utility model discloses a corn planting topdressing device. In use, fertilizer and water are added to the mixing tank for mixing. The fertilizer flows into the moving pipe under gravity. An electric actuator moves the moving pipe and the topdressing pipe, bringing the topdressing pipe to the corn seedlings, which in turn moves the stop lever to the seedlings. At this point, the worker pushes the frame, moving the moving pipe, the topdressing pipe, and the stop lever. When the stop lever contacts the corn seedlings, it stops moving due to the obstruction of the seedlings. The worker then pushes the frame further, causing the stop lever to rotate, which in turn moves the topdressing pipe... The fertilizer pipe and the discharge plate rotate. As the discharge plate rotates, the through hole on the discharge plate rotates to align with the discharge trough. At this time, fertilizer can flow from the mixing box through the moving pipe, the discharge trough, and the through hole into the topdressing pipe, and finally be applied to the vicinity of the roots of the corn seedlings. When the topdressing pipe is removed from the corn seedlings, the baffle, the topdressing pipe, and the discharge plate are reset under the action of the elastic member, thereby resealing the moving pipe and the topdressing pipe to prevent the fertilizer from continuing to flow out. This achieves precise application of fertilizer, avoids fertilizer waste, and improves the efficiency of fertilization. Attached Figure Description

[0020] This utility model provides a corn planting topdressing device, including a frame 101, a mixing box 102, and a topdressing component 104. The topdressing component 104 includes a moving pipe 105, a topdressing pipe 106, a sealing plate 107, a discharge plate 108, an elastic member 109, a stop bar 110, and a stirring member 118. The moving pipe 105 includes a telescopic pipe 111 and a connecting pipe 112. The elastic member 109 includes a rotating shaft 113 and a torsion spring 114. The stop bar 110 includes a rod body 115, a sliding sleeve 116, and a locking member 117. The stirring member 118 includes a stirring shaft 119 and a stirring rod 120. The rotation of the stop bar 110 after contacting the corn seedling drives the topdressing pipe 106. 6. The discharge plate 108 rotates, aligning the through hole 123 on the discharge plate 108 with the discharge trough 124. At this time, fertilizer can flow out of the topdressing pipe 106 through the discharge trough 124 and the through hole 123. When the stop bar 110 leaves the corn seedling, the discharge plate 108 and the topdressing pipe 106 are reset under the action of the elastic member 109, thereby sealing the topdressing pipe 106 to prevent fertilizer from flowing out. This allows the fertilizer to be applied according to the position of the corn seedling, avoiding fertilizer waste and improving topdressing efficiency. It is understood that the aforementioned solution can be used to avoid fertilizer waste, and can also be used to drive the discharge plate 108 and the topdressing pipe 106 to reset.

[0021] In this specific embodiment, the mixing tank 102 is fixedly installed on one side of the frame 101. Four casters 103 are also installed on the side of the frame 101 away from the mixing tank 102. The casters 103 facilitate the movement of the frame 101 by the workers. The top of the mixing tank 102 is provided with a feed inlet for adding fertilizer and water into the mixing tank 102.

[0022] The moving pipe 105 is connected to and communicates with the mixing tank 102, and is located on one side of the mixing tank 102. The topdressing pipe 106 is rotatably connected to and communicates with the moving pipe 105. The sealing plate 107 is fixedly connected to the moving pipe 105 and is located inside the moving pipe 105. The discharge plate 108 is fixedly connected to the topdressing pipe 106 and is located inside the topdressing pipe 106. The elastic member 109 is disposed on the discharge plate 108. The baffle 110 is connected to the topdressing pipe 106 and is disposed on the topdressing pipe 106. Two topdressing components 104 are provided, and are respectively located on both sides of the mixing tank 102. On the side, two electric push rods 121 are also installed on the frame 101. The two electric push rods 121 are respectively installed on both sides of the frame 101, and the output ends of the two electric push rods 121 are respectively connected to the two moving tubes 105. The sealing plate 107 is provided with a discharge groove 124, which penetrates the sealing plate 107. The discharge plate 108 is provided with a through hole 123, which penetrates the discharge plate 108. The elastic member 109 drives the discharge plate 108 to rotate, so that the through hole 123 on the discharge plate 108 is misaligned with the discharge groove 124. At this time, the moving tube 105 and the fertilizer pipe 106 are sealed, and the fertilizer cannot be discharged.

[0023] In use, fertilizer and water are added to the mixing tank 102 for mixing. The fertilizer flows into the moving pipe 105 under gravity. The electric actuator 121 moves the moving pipe 105 and the topdressing pipe 106, causing the topdressing pipe 106 to move to the corn seedlings, which in turn moves the stop lever 110 to the corn seedlings. At this time, the worker pushes the frame 101, which in turn moves the moving pipe 105, the topdressing pipe 106, and the stop lever 110. When the stop lever 110 contacts the corn seedlings, it stops moving due to the obstruction of the seedlings. The worker then pushes the frame 101 further, causing the stop lever 110 to rotate, which in turn moves the topdressing pipe 106 and the discharge plate 10. 8. As the discharge plate 108 rotates, the through hole 123 on the discharge plate 108 rotates to align with the discharge trough 124. At this time, fertilizer can flow from the mixing box 102 through the moving pipe 105, the discharge trough 124, and the through hole 123 into the topdressing pipe 106, and finally be applied to the vicinity of the roots of the corn seedlings. When the topdressing pipe 106 is removed from the corn seedlings, the stop bar 110, the topdressing pipe 106, and the discharge plate 108 are reset under the action of the elastic member 109, thereby resealing the moving pipe 105 and the topdressing pipe 106 to prevent the fertilizer from continuing to flow out. This achieves precise application of fertilizer, avoids fertilizer waste, and improves the efficiency of fertilization.

[0024] Secondly, the telescopic pipe 111 is connected to and communicates with the mixing box 102; the connecting pipe 112 is connected to the telescopic pipe 111, rotatably connected to the topdressing pipe 106, and fixedly connected to the sealing plate 107; the connecting pipe 112 is connected to the output end of the electric push rod 121, and the telescopic pipe 111 can extend and retract. The electric push rod 121 drives the connecting pipe 112 to move left and right, thereby driving the topdressing pipe 106 to move, so that the topdressing pipe 106 can move to the corn seedling. Through the extension and retraction of the telescopic pipe 111, the telescopic pipe 111 will not interfere with the movement of the connecting pipe 112.

[0025] Meanwhile, the rotating shaft 113 is rotatably connected to the sealing plate 107 and fixedly connected to the discharge plate 108, and is located on one side of the discharge plate 108; the two ends of the torsion spring 114 are respectively connected to the rotating shaft 113 and the sealing plate 107, and the torsion spring 114 is sleeved on the rotating shaft 113; when the stop rod 110, the topdressing pipe 106 and the discharge plate 108 rotate, the discharge plate 108 drives the rotating shaft 113 to rotate, thereby causing the rotating shaft 113 to drive the torsion spring 114 to deform and store elastic potential energy; when the stop rod 110 is no longer obstructed due to leaving the corn seedling, the torsion spring 114 releases the stored elastic potential energy, drives the rotating shaft 113 to rotate in the opposite direction, thereby driving the discharge plate 108 to reset, and the reset of the discharge plate 108 causes the through hole 123 and the discharge trough 124 to be misaligned again, thereby sealing the topdressing pipe 106 and preventing fertilizer from continuing to flow out.

[0026] In addition, the sliding sleeve 116 is slidably connected to the topdressing pipe 106 and is sleeved on the topdressing pipe 106; the rod body 115 is fixedly connected to the sliding sleeve 116 and is located on one side of the sliding sleeve 116; the locking member 117 is threadedly connected to the sliding sleeve 116 and passes through the sliding sleeve 116 to abut against the topdressing pipe 106; by loosening the locking member 117, the sliding sleeve 116 can slide up and down on the topdressing pipe 106, thereby driving the rod body 115 to move up and down, so as to adapt to corn seedlings of different heights. When the height of the rod body 115 is adjusted to the correct position, the locking member 117 is tightened again to lock the sliding sleeve 116 and the rod body 115.

[0027] Finally, the stirring shaft 119 is rotatably connected to the mixing tank 102 and is located inside the mixing tank 102; the stirring rod 120 is fixedly connected to the stirring shaft 119 and is disposed on the stirring shaft 119; multiple stirring rods 120 are disposed and evenly distributed on the stirring shaft 119; a rotary motor 122 is also installed on the top of the mixing tank 102, and the output end of the rotary motor 122 is connected to the stirring shaft 119. The rotary motor 122 drives the stirring shaft 119 to rotate, thereby driving multiple stirring rods 120 to rotate, thereby fully mixing the fertilizer and water inside the mixing tank 102.

[0028] When using the corn planting topdressing device of this utility model, the operator pushes the frame 101 to move, which in turn moves the moving pipe 105, the topdressing pipe 106, and the stop bar 110. When the stop bar 110 contacts the corn seedling, it rotates under the action of the corn seedling, which in turn rotates the topdressing pipe 106 and the discharge plate 108, aligning the through hole 123 on the discharge plate 108 with the discharge trough 124. At this time, the fertilizer inside the mixing box 102 can pass through the moving pipe 105. The discharge trough 124, the through hole 123, and the topdressing pipe 106 discharge fertilizer to apply it to the corn seedlings. When the baffle 110 leaves the corn seedlings, the rotating shaft 113, the discharge plate 108, the topdressing pipe 106, and the baffle 110 are reset under the action of the torsion spring 114, thereby causing the through hole 123 to be misaligned with the discharge trough 124. At this time, the topdressing pipe 106 is sealed to prevent fertilizer from continuously flowing out, thus achieving the purpose of applying fertilizer to the corn seedlings, avoiding fertilizer waste, and improving the efficiency of topdressing.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
