Description

Technical Field

[0001] The invention relates to the technical field of air supply devices for transplanters, in particular to an air supply device and an automatic transplanter thereof. Background Art

[0002] The automatic transplanter is mainly composed of working parts such as a feeder, a seedling guide tube, a seedling supporter, a furrow opener and a covering and pressing wheel. When working, the air supply equipment pushes the clamping assembly to separate the seedlings, and then the seedlings are put into the feeding tube of the feeder. When the feeding tube rotates to the top of the seedling guide tube, the valve under the feeding tube opens, and the seedlings fall into the seedling guide tube by gravity. The seedlings are introduced into the seedling furrow opened by the furrow opener through the inclined seedling guide tube. With the support of the grid-type seedling supporter, the seedlings are in an upright state. Then, under the action of the covering soil flow formed between the furrow opener and the covering and pressing wheel, the seedlings are covered and pressed to complete the planting process. However, since transplanters are mainly used for field operations, a large amount of dust often occurs during field operations. When the fine dust from the outside enters the gas tank, it may block the valve. Moreover, when the air in the working environment is relatively humid, the humid gas will mix with the dust after entering the gas tank, thereby aggravating the blockage of the valve. For this reason, we have introduced an air supply device and an automatic transplanter thereof. Summary of the Invention

A first valve 10 is fixedly installed at one end of the connection box 2. The gas tank 3 is installed together with the transplanter 1, and the air pump located in the transplanter 1 is connected to the first valve 10 through a pipeline. When the transplanter 1 is started and the air pump is working, the gas generated by the air pump will enter the connection box 2 through the first valve 10 for processing, and the lower end is also fixedly connected to a second valve 11. Through the setting of the second valve 11, the water source deposited at the bottom of the connection box 2 after condensation can be discharged; The upper end of the gas tank 3 is fixedly connected with a pressure relief valve 8, an air guide pipe 9 and a solenoid valve 35.

The output end of the solenoid valve 35 is fixedly connected to the connecting pipe 5, and the end of the connecting pipe 5 away from the solenoid valve 35 is fixedly connected to the U-shaped plate 12. After the solenoid valve 35 is started, the gas in the gas tank 3 will enter the U-shaped plate 12 through the connecting pipe 5, and a sealing mechanism is provided in the U-shaped plate 12.

[0015] Example 2: On the basis of Example 1, in order to block the moisture in the humid air, the movable filtering mechanism includes a connecting frame 21, which is movably connected to the connecting box 2, and a first filter plate 27 is movably connected to the inner side of the connecting frame 21, and a positioning plate 34 is fixedly connected to the inner side of the connecting frame 21. A limiting plate 30 is movably installed on one side of the connecting frame 21 through a first knob 33, and a second filter plate 20 is clamped and installed between the positioning plate 34 and the limiting plate 30. The limiting plate 30 can be unscrewed by loosening the first knob 33. At this time, the second filter plate 20 can be replaced, and the second filter plate 20 is positioned by the positioning plate 34. A blocking plate 28 is fixedly connected to the inner side of the connecting box 2, and the blocking plate 28 contacts the connecting frame 21. A telescopic cylinder 4 is fixedly connected to the outer side of the connecting box 2, and the output end of the telescopic cylinder 4 extends into the connecting box 2 and is fixedly connected to the connecting frame 21; The upper and lower ends of the connecting frame 21 are fixedly connected to the first T-shaped rod 23, the first T-shaped rod 23 is slidably connected to the first T-shaped slot 22, the first T-shaped slot 22 is opened on the inner side of the connecting box 2, the first filter plate 27 is connected to the mounting bracket 26 through the second knob 25, and the mounting bracket 26 is fixedly connected to the second T-shaped rod 32 on both sides. The second T-shaped rod 32 is slidably connected to the second T-shaped slot 31, and the second T-shaped slot 31 is opened in the connecting frame 21. The connecting frame 21 is limited by the first T-shaped rod 23 sliding in the first T-shaped slot 22. When one end of the connecting frame 21 contacts the U-shaped plate 12 and stops moving, a part of the first T-shaped rod 23 slides in the first T-shaped slot 22, and the connecting frame 21 will block the clearance hole 17. When the connecting frame 21 is moved back into the connecting box 2, one end of the connecting frame 21 will still block the clearance hole 17; The upper end of the first filter plate 27 is fixedly connected to the folding cloth 24, and the upper end of the folding cloth 24 is fixedly connected to the connecting frame 21. The upper end of the mounting bracket 26 is fixedly connected to the elastic pull rope 19. The upper end of the elastic pull rope 19 passes through the connecting frame 21 and the first T-shaped rod 23 and is fixedly connected to the first T-shaped slot 22. The telescopic cylinder 4 is started to drive the connecting frame 21 to move, and the connecting frame 21 enters the U-shaped plate 12 along the make way hole 17. At the same time, during the movement of the connecting frame 21, the upper end of the elastic pull rope 19 is connected to the first T-shaped slot 22. Therefore, when the connecting frame 21 moves, the mounting bracket 26 on which the first filter plate 27 is installed will be driven to move upward. At this time, the folding cloth 24 will be folded, and the first filter plate 27 will move upward so that it is staggered with the second filter plate 20. The cooling mechanism includes a plurality of copper plates 16, which are arranged between the mounting plate 14 and the connection box 2, and both ends are fixedly connected to the inner side of the connection box 2. The mounting plate 14 is fixedly connected to the inner side of the connection box 2. A refrigeration plate 15 is fixedly installed in the connection box 2, and the refrigeration plate 15 is in contact with the plurality of copper plates 16. When the external environment is relatively humid, the refrigeration plate 15 is turned on. After the refrigeration plate 15 in the connection box 2 is started, it cools down the plurality of copper plates 16. When humid gas enters the connection box 2, the humid gas will sequentially contact the plurality of copper plates 16 arranged in an inclined shape, and the moisture in the gas will be condensed and blocked by the copper plates 16. The blocking mechanism includes two L-shaped blocking plates 6, which are movably installed in slots 18 through limit knobs 7. The slots 18 are opened in the U-shaped plate 12, and a plurality of transverse ventilation holes 13 are opened in one L-shaped blocking plate 6.

[0016] In addition, in order to achieve the above-mentioned purpose, the present invention also provides an automatic transplanter, comprising the above-mentioned air supply device.

[0017] Working principle: when in use, the gas tank 3 is installed together with the transplanter 1, the air pump located in the transplanter 1 is connected to the first valve 10 through the pipeline, and the air guide pipe 9 is connected to the corresponding electromagnetic valve component in the transplanter 1. After the connection is completed, the first valve 10 is opened. At this time, the gas generated by the air pump located in the transplanter 1 will enter the connection box 2 through the first valve 10. When the external environment is relatively humid, the refrigeration plate 15 is turned on at this time. The refrigeration plate 15 located in the connection box 2 cools down the several copper plates 16 after startup. When the humid gas enters the connection box 2, the humid gas will contact the several copper plates 16 arranged in an inclined shape in turn, and the moisture in the gas will be condensed and blocked by the copper plates 16, and finally fall into the connection box 2. After that, the gas will pass through the first filter plate 27 and the second filter plate 20 in turn, and then enter the gas tank 3 through the one-way valve 29 for storage; When the first filter plate 27 and the second filter plate 20 need to be cleaned, the telescopic cylinder 4 is started to drive the connecting frame 21 to move, and the connecting frame 21 enters the U-shaped plate 12 along the clearance hole 17. At the same time, during the movement of the connecting frame 21, the upper end of the elastic pull rope 19 is connected to the first T-slot 22. Therefore, when the connecting frame 21 moves, the mounting frame 26 on which the first filter plate 27 is installed will be driven to move upward. At this time, the folding cloth 24 will be folded, and the first filter plate 27 will move upward to be staggered with the second filter plate 20. When the connecting frame 21 contacts one end of the U-shaped plate 12, the telescopic cylinder 4 is closed. At the same time, the solenoid valve 35 is started, and the gas in the gas tank 3 will enter the U-shaped plate 12 through the connecting pipe 5. The gas entering the U-shaped plate 12 will pass through the second filter plate 20 and the first filter plate 27 in sequence, and the filter surfaces of the first filter plate 27 and the second filter plate 20 will be backblown, so that the impurities adhering to and blocking the filter surfaces are blown off. Then, the gas is discharged into the external environment through the several air vents 13. When the cleaning is completed, the telescopic cylinder 4 is started to pull the mounting frame 26 with the first filter plate 27 installed into the connecting box 2 again. At this time, under the action of the gravity of the mounting frame 26 and the first filter plate 27, the mounting frame 26 moves downward to return to its initial position, and the folding cloth 24 is unfolded again. When the first filter plate 27 and the second filter plate 20 need to be replaced, the connecting frame 21 is re-entered into the U-shaped plate 12. At this time, the limit knob 7 is loosened and the L-shaped blocking plate 6 is pulled upward. When the L-shaped blocking plate 6 is pulled out, the first filter plate 27 and the second filter plate 20 can be replaced by loosening the second knob 25 and the first knob 33 in turn. After the replacement is completed, the connecting frame 21 is re-entered into the connecting box 2, and the L-shaped blocking plate 6 is reinserted into the slot 18.
