Description

Technical Field

[0001] The present invention relates to a device for applying water and fertilizer in a tobacco field, belonging to the technical field of tobacco fertilization. Background Art

[0002] Centering around the new planting concept of "timely, strong seedlings, high ridges and deep planting", the well-cellar method for transplanting tobacco seedlings has been gradually promoted in the flue-cured tobacco growing areas of our country. Specifically, floating tobacco seedlings of a certain leaf age are vertically dropped into the "well-cells" pre-dug on the tobacco ridges. The main operation links during transplanting are ridge formation, film mulching, hole punching (making well-cells), seedling dropping (transplanting tobacco seedlings), drenching root-fixing water, applying topdressing liquid, checking and supplementing seedlings, and filling soil to seal the mouth.

[0003] To achieve the early and rapid growth of tobacco plants, root-fixing water, fertilizer and medicine water are drenched after transplanting seedlings, and a special topdressing liquid is applied 7 - 10 days after transplanting, so that the tobacco seedlings can absorb nutrients in time, grow rapidly, and enter the early and vigorous growth stage as soon as possible. However, the amount of fertilizer applied needs to be accurately quantified according to the actual situation of the planting plot and tobacco seedlings. Accurate fertilization can not only obtain high-quality tobacco leaf products, increase the income from tobacco planting, but also reduce fertilizer loss and the pollution of farmland water bodies. However, it is very difficult for the existing fertilization devices to achieve this effect. Summary of the Invention

[0048] It further includes a lifting component 502. The lifting component 502 includes a cylinder 5021 and a mounting bracket 5022. The cylinders 5021 are arranged on both sides above the main board 1, and the output ends of the cylinders 5021 pass through the main board 1 and are connected to the mounting bracket 5022. An installation frame 501 is arranged below the main board 1, and a plurality of through holes 507 are arranged on the installation frame 501.

First springs 5023 are arranged on both sides of the outer wall of the material cylinder component 503, and the first springs 5023 are connected to the bottom of the mounting bracket 5022.

[0049] The lifting component 502 can drive the material cylinder component 503 to descend, thereby reducing the height of fertilization and avoiding the situation of water and fertilizer splashing.

[0050] As Figure 3 shown, the material cylinder component 503 includes a liquid storage cylinder 5031, a telescopic tube 5032, and a lower cylinder 5033 connected in sequence from top to bottom. A piston plate is arranged in the liquid storage cylinder 5031. The top of the piston plate is connected to a piston rod 5038, and the piston rod 5038 extends outside the liquid storage cylinder 5031 and is connected to the bottom of the mounting bracket 5022. A sealing plate 5039 that fits against the inner wall of the liquid storage cylinder 5031 is arranged on the outer edge of the top surface of the piston plate, and the sealing plate 5039 also extends outside the liquid storage cylinder 5031.

[0051] A first mounting block 5034 is arranged on the outer wall of the liquid storage cylinder 5031, and a second mounting block 5035 is arranged on the lower cylinder 5033. They are connected by an adjusting rod 5036. The upper end of the adjusting rod 5036 is threadedly connected to the first mounting block 5034, and the lower end is rotatably connected to the second mounting block 5035. During use, the adjusting rod 5036 can be rotated according to different amounts of water and fertilizer application, so that the length of the telescopic tube 5032 changes and is converted into a change in the capacity of the material cylinder component 503, thereby realizing the adjustment of different quantitative liquid fertilizer application.

[0052] At the bottom of the lower cylinder body 5033, there is a discharge hopper 5037. A sealing cover 5062 for blocking the discharge hopper 5037 is provided on the discharge hopper 5037. On both sides of the top surface of the sealing cover 5062, there are second springs 5061 connected to the lower cylinder body 5033. Under the action of the first spring 5023 and the second spring 5061, the barrel assembly 503 and the discharge assembly 506 can be better matched to realize automatic discharging operation.

[0053] The discharge assembly 506 is arranged on the mounting frame 501 and corresponds to the barrel assembly 503 one by one. It includes a limit frame 5063 and a discharge rod 5064. The limit frame 5063 is composed of two L-shaped bent plates with their horizontal parts facing each other and forming a gap. The upper end of the discharge rod 5064 corresponds to the bottom port of the discharge hopper 5037, and the lower end is connected to the limit frame 5063.

[0054] The infusion assembly 505 includes a cylinder 5055 and a main pipe 5051 arranged on the main board 1. The cylinder 5055 is radially arranged on the liquid storage cylinder 5031 and is communicated with the liquid storage cylinder 5031. A plurality of hoses 5054 are provided on the main pipe 5051, and the hoses 5054 are communicated with the liquid inlet of the cylinder 5055. At the liquid outlet of the cylinder 5055, there is an opening and closing member. The opening and closing member includes a variable diameter pipe 5056. The variable diameter pipe 5056 is coaxially arranged inside the cylinder 5055. It includes a large-end face pipe orifice and a small-end face pipe orifice. The large-end face pipe orifice is connected to the inner wall of the liquid outlet of the cylinder 5055, and a plurality of limit claws 5058 for limiting the plugging ball 5059 are axially equidistantly arranged on the inner wall of the pipe orifice. The large-end face pipe orifice and the small-end face pipe orifice are smoothly connected through a curved surface variable diameter part 5057. The plugging ball 5059 is arranged in the curved surface variable diameter part 5057.

[0055] The limit claws 5058 are arc-shaped. When the limit claws 5058 are in contact with the plugging ball 5059, part of the plugging ball 5059 is exposed into the liquid storage cylinder 5031, and the cylinder 5055 is communicated with the liquid storage cylinder 5031; when the limit claws 5058 are not in contact with the plugging ball 5059, the plugging ball 5059 is pressed against the curved surface variable diameter part 5057, and the cylinder 5055 is not communicated with the liquid storage cylinder 5031.

[0056] The plugging plate 5039 can radially extrude the plugging ball 5059 during the process of the cylinder 5021 driving the barrel assembly 503 to descend, so that the plugging ball 5059 is extruded into the variable diameter pipe 5056 and closely adheres to the inner wall of the curved surface variable diameter part 5057, realizing the plugging between the variable diameter pipe 5056 and the cylinder 5055, and preventing new liquid fertilizer from entering the barrel assembly 503.

[0057] The liquid suction component 504 includes a liquid storage tank 5041 and a delivery pump 5042 arranged on the main board 1. The liquid outlet of the liquid storage tank 5041 is connected to the main pipe 5051 through a first connecting pipe 5052. The first connecting pipe 5052 is provided with a control valve 5053 for the convenience of the staff to control the flow. The liquid inlet of the liquid storage tank 5041 is connected to the liquid outlet of the delivery pump 5042. The liquid inlet of the delivery pump 5042 is connected to the tank body 401 of the mixing mechanism 4 through a second connecting pipe 5043.

[0058] like Figure 6 As shown, an arc plate 5049 is provided inside the tank body 401, and a plurality of vertical grooves 50410 are provided on the surface of the arc plate 5049. The arc plate 5049 and the tank body 401 are enclosed to form an area, and the second connecting pipe 5043 extends into the area and is connected to the spiral hose 5044. The lower end of the spiral hose 5044 passes through the floating block 5046 and is connected to the suction head 5045. The bottom of the floating block 5046 is connected to the counterweight block 5048 through the telescopic rod 5047. The floating block 5046 is subject to buoyancy due to its light material characteristics. With the interaction of the telescopic rod 5047 and the counterweight block 5048, the dynamic movement of the floating block 5046 can be made more stable, and the collision and contact between the suction head 5045 and the bottom of the tank body 401 caused by the low liquid level in the tank body 401 can also be avoided. Example

[0059] On the basis of Example 1, the mixing mechanism 4 of this embodiment includes a tank body 401 arranged on the main board 1, a stirring component 402 is arranged inside the tank body 401, and a flipping component 403 is connected to the end of the stirring component 402.

[0060] like Figure 4 As shown, the stirring assembly 402 includes a motor 4021, which is arranged at the top of the tank body 401, and its output end is connected to the vertical rod 4022, and the vertical rod 4022 extends to the inside of the tank body 401 and is connected to the tipping assembly 403. A plurality of stirring plates 4023 are arranged around the vertical rod 4022, and a plurality of mounting grooves 4024 are provided on the stirring plates 4023, and a toggle roller 4025 is rotatably connected in the mounting grooves 4024. A limit slide plate 4026 is also inserted on the top of the stirring plate 4023, and a suspension plate 4027 is arranged above the limit slide plate 4026, and the suspension plate 4027 is designed with a lightweight material.

[0061] like Figure 5As shown, the flip assembly 403 includes a transmission box 4032 and a rotating rod 4031. The rotating rod 4031 is penetrated through the side of the transmission box 4032, and both ends are rotatably connected to the inner arm of the tank body 401. The rotating rod 4031 is located on both sides of the transmission box 4032 and is evenly provided with a plurality of flip blades 4033. The vertical rod 4022 passes through the top of the transmission box 4032 and extends to the inside of the transmission box 4032 to be connected with a bevel gear 4034. The rotating rod 4031 is located inside the transmission box 4032 and is penetrated with a bevel gear 4034, and the two bevel gears 4034 are meshed with each other.

[0062] A stirring system that completely covers the liquid level range of the tank 401 from top to bottom is formed by the suspension plate 4027, the limiting slide plate 4026, the stirring plate 4023 and the flip blade 4033. At the same time, in this stirring system, the suspension plate 4027 can change with the change of the liquid level height to achieve maximum effective stirring, prevent some stirring blades from idling, increase costs or the stirring range of the stirring blades cannot cover the liquid level height in the initial state, resulting in poor stirring effect.

[0063] The working principle of the present invention is: by pushing the handle 3 to move the vehicle body onto the chimney, the chimney is located in the lower middle part of the main board 1, and after putting water and fertilizer into the tank body 401, the motor 4021 is started, and the motor 4021 drives the vertical rod 4022 and the stirring plate 4023 to rotate. At this time, under the influence of the water flow, the stirring roller 4025 in the installation groove 4024 rotates spontaneously to accelerate the stirring process.

[0064] Since the limiting slide plate 4026 and the stirring plate 4023 are connected by plugging and the suspension plate 4027 is designed with a light material, the suspension plate 4027 can always float at the high point of the liquid level in the tank 401, and the limiting slide plate 4026 and the suspension plate 4027 will rotate synchronously with the stirring plate 4023. In this process, under the action of two meshing bevel gears 4034, the vertical rod 4022 will drive the rotating rod 4031 to rotate synchronously, thereby driving the flipping blades 4033 to rotate.

[0065] After the mixing is completed, the adjusting rod 5036 is rotated according to the different water and fertilizer application amounts, and the adjusting rod 5036 drives the lower cylinder 5033 to move vertically, and the telescopic tube 5032 is then axially extended or telescoped.

[0066] When the fertilization work starts, the delivery pump 5042 is started, and the delivery pump 5042 is connected to the second connecting pipe 5043, the spiral hose 5044 and the suction head 5045 to synchronously deliver the mixed water and fertilizer to the storage tank 5041. The control valve 5053 is opened, and the water and fertilizer in the liquid storage tank 5041 will enter the first connecting pipe 5052, the main pipe 5051, the hose 5054 in sequence, and then enter the cylinder 5055. Under the impact of the water and fertilizer, the blocking ball 5059 contacts the limiting claw 5058, so that part of the blocking ball 5059 is exposed to the liquid storage cylinder 5031 but cannot be removed from the reducer 5056. At this time, the cylinder 5055 and the liquid storage cylinder 5031 are connected, and the water and fertilizer can enter the barrel assembly 503 through the reducer 5056, and the discharge hopper 5037 is blocked by the blocking cover 5062 at this time, so the barrel assembly 503 will be full of water and fertilizer.

[0067] Then, the cylinder 5021 is started, and the cylinder 5021 drives the mounting frame 5022 to move downward, and at the same time drives the barrel assembly 503 to pass through the through hole 507 and move downward. When the discharge hopper 5037 passes over the limit frame 5063, the second mounting block 5035 is synchronously in contact with the limit frame 5063, and at the same time, the discharge rod 5064 is inserted into the discharge hopper 5037 and pushes the blocking cover 5062, and the second spring 5061 is compressed, and the gap between the blocking cover 5062 and the discharge hopper 5037 is used to realize the discharge of materials and liquid.

[0068] During the above process, after the second mounting block 5035 is limited by the limit frame 5063, the liquid storage cylinder 5031 cannot move downward either, but the mounting frame 5022 continues to press downward quickly and drives the piston rod 5038 to move downward quickly, which causes the first spring 5023 to be compressed quickly, and the sealing plate 5039 moves synchronously and quickly with the piston rod 5038. The arc-shaped sealing plate 5039 moves along the inner wall of the liquid storage cylinder 5031, and will radially squeeze the sealing ball 5059, so that the sealing ball 5059 is squeezed into the reducer 5056 and tightly adheres to the inner wall of the curved reducer 5057, thereby achieving sealing between the reducer 5056 and the cylinder 5055, so that new liquid fertilizer cannot enter the barrel assembly 503 until the piston plate moves downward and the interior of the barrel assembly 503 is emptied.

[0069] After the fertilization operation is completed, the cylinder 5021 drives the barrel assembly 503, the piston 5038 rod and the sealing plate 5039 to return to their original positions, and the infusion assembly 505 and the discharge assembly 506 continue to work, continue to move the device, and carry out the fertilization operation of the next ridge section.

[0070] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
