Description

Technical Field

[0001] The present invention relates to the technical field of seedling cultivation equipment, in particular to a tree seedling greenhouse sprayer and an irrigation device. Background Art

[0002] At present, when cultivating tree seedlings, in order to provide a good growth environment for the seedlings and improve the survival rate of the seedlings, the cultivation work is usually carried out in a greenhouse, and it is necessary to spray the seedlings with liquid medicine through irrigation devices from time to time and fertilize them appropriately.

[0003] Traditional irrigation devices usually consist of a water tank, a water pump and a sprayer. Currently, during the entire process of spraying medicine or fertilizer, workers have to mix the medicine or fertilizer with water in the sprayer according to the proportion. This process requires manual operation throughout the process, which means that workers not only need to mix the fertilizer, but also have to control the angle of the sprayer nozzle, which is very laborious. In addition, if too much fertilizer is poured in at one time, the mixing efficiency will be slow, resulting in poor mixing effect, which in turn affects the cultivation effect of tree seedlings. For this reason, we propose a tree seedling greenhouse sprayer and irrigation device. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a tree seedling greenhouse sprayer and irrigation device, which has the following beneficial effects:

[0016] 1. The tree seedling greenhouse sprayer intermittently controls the flow of water in the water inlet pipe, utilizes the kinetic energy of water, and cooperates with the use of vertical poles, contact blocks, compression springs, conical grooves, U-shaped racks, connecting gears, rotating rods, triangular blocks, primary bevel gear plates, secondary bevel gear plates, connecting rods, and sealing plugs. The opening at the bottom of the discharge pipe can be intermittently opened, so that the fertilizer in the storage chamber can intermittently flow into the mixing chamber. This design can avoid excessive introduction of fertilizer at one time, which affects the mixing rate and effect of the fertilizer. At the same time, the kinetic energy of water is used for material discharge, which reduces manual operation and avoids the need for staff to control the angle of the sprinkler while discharging material, thereby improving irrigation efficiency.

[0017] 2. The tree seedling greenhouse sprayer is arranged so that the outer shell is in an unfixed state through the setting of the support, top rod, connecting piece, support plate, bottom rod, lower pressure block, slide rod, fixed cylinder and reset spring. The intermittent impact of water in the water inlet pipe can also be used to make the outer shell vibrate. The fertilizer in the mixing chamber is shaken apart by vibration, which is conducive to quickly mixing the fertilizer and water and improving the mixing efficiency. At the same time, through the mutual cooperation between the L-shaped rack, the rotating gear and the stirring paddle, when the outer shell vibrates up and down, the L-shaped rack is engaged with the rotating gear, and therefore, the rotating gear and the stirring paddle can be driven to rotate. The stirring paddle can be used to stir the water and fertilizer in the mixing chamber again, further improving the mixing effect.

[0018] 3. The tree seedling greenhouse sprayer, through the mutual cooperation between the piston disc, the inflation hose, the airbag and the elastic part, can expand or contract the airbag through the intermittent compression of the sliding rod. With this design, when the bottom of the shell collides with the support part, the expansion of the airbag can reduce the impact force on the shell, which is beneficial to protect the shell and extend the service life of the shell.

[0019] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The present invention intermittently controls the water pump to start, and utilizes the kinetic energy of water to make the opening at the bottom of the discharge pipe intermittently open, so that the fertilizer in the storage chamber can intermittently flow into the mixing chamber, avoiding too much fertilizer being introduced at one time, which affects the mixing rate and effect of the fertilizer. At the same time, the kinetic energy of water is used for material discharge, which reduces manual operation and avoids the need for staff to control the angle of the nozzle while discharging the material, thereby improving the irrigation efficiency. The intermittent impact of the water in the water inlet pipe can also be used to vibrate the outer shell, and the fertilizer in the mixing chamber is shaken off by vibration, which is conducive to rapid mixing of fertilizer and water and improved mixing efficiency.

Two triangular blocks 1408 are fixed on the top of the partition 7, and the rotating rod 1407 It is rotatably connected to the two triangular blocks 1408 through bearings, and a main bevel gear plate 1409 is fixed to one end of the rotating rod 1407. The outer surface of the main bevel gear plate 1409 is meshed with the secondary bevel gear plate 1410. A connecting rod 1411 is fixed at the axis of the secondary bevel gear plate 1410. The connecting rod 1411 is rotatably connected to the partition 7 through bearings. A sealing plug 1412 is fixed to the bottom end of the connecting rod 1411. The diameter of the sealing plug 1412 is larger than the diameter of the discharge pipe 11. The sealing plug 1412 fits tightly against the bottom of the partition 7. A rectangular groove 20 is provided on the partition 7, and the U-shaped rack 1405 is slidably connected in the rectangular groove 20.

[0034] In the present invention, when the sprayer is in use, the top of the water inlet pipe 13 is connected to the water outlet of the external water pump, and a feed port is provided on the top of the top cover 15. Fertilizer can be added to the storage chamber 8 through the feed port, so that the fertilizer is accumulated on the top of the conical bucket 6. When the materials need to be mixed, the staff only needs to control the water pump to start intermittently, so that the water in the water tank intermittently rushes down from the water inlet pipe 13. Since the contact block 1402 is located directly below the water flow, the water flow will impact the contact block 1402, so that it can slide downward on the outer surface of the vertical rod 1401 and pass through the conical groove 1 The setting of 404 allows the impact force of the water flow to converge to one point, which is used to enhance the impact force of the water flow on the contact block 1402. When the contact block 1402 slides downward, it compresses the compression spring 1403 and also drives the U-shaped rack 1405 to move together. Since the U-shaped rack 1405 is engaged with the connecting gear 1406, it can drive the connecting gear 1406 and the rotating rod 1407 to rotate. The setting of the rectangular groove 20 allows the U-shaped rack 1405 to pass through, avoiding affecting the movement of the U-shaped rack 1405. The rotating rod 1407 drives the main cone The gear plate 1409 rotates, and since the main bevel gear plate 1409 is meshed with the secondary bevel gear plate 1410, it drives the secondary bevel gear plate 1410 and the connecting rod 1411 to rotate, and the connecting rod 1411 drives the sealing plug 1412 to rotate. When the contact block 1402 rotates to the area deviating from the bottom of the discharge pipe 11, the fertilizer on the top of the conical bucket 6 will flow into the mixing chamber 10 from the discharge pipe 11, and the impacted water will also flow into the mixing chamber 10 from the water inlet hole 12, so that the fertilizer and water are mixed in the mixing chamber 10. When the water pump stops discharging water, the compressed spring The elastic force of spring 1403 resets the contact block 1402, thereby driving the sealing plug 1412 to re-block the bottom of the discharge pipe 11, so that the fertilizer no longer falls. This design can avoid excessive fertilizer introduction at one time, which affects the mixing rate and effect of the fertilizer. At the same time, the kinetic energy of water is used for feeding, which reduces manual operation and avoids the need for staff to control the angle of the nozzle while feeding, thereby improving irrigation efficiency. The outer shell 3 can be made of transparent material, which is convenient for observing the mixing situation inside the mixing chamber 10 and the feeding situation inside the storage chamber 8.

[0037] In the present invention, on the basis of embodiment 1, since the water inlet pipe 13 slides in the shell 3, when the shell 3 is impacted by the water flow, a downward pressure is generated on the shell 3, thereby driving the top rod 501 to flip downward on the outer surface of the connecting member 502, causing the slide rod 506 to slide downward in the fixed cylinder 507, compressing the reset spring 508, and when the water pump stops discharging water, the shell 3 is reset by the elastic force of the reset spring 508. Therefore, the intermittent start-up of the water pump will cause the shell 3 to vibrate in the vertical direction, and the vibration can be used to The fertilizer in the mixing chamber 10 is shaken apart, which is beneficial to the rapid mixing of the fertilizer and water. In addition, due to the meshing connection between the L-shaped rack 1701 and the rotating gear 1702, the rotating gear 1702 can also be rotated by the up and down movement of the shell 3, and the rotating gear 1702 drives the stirring paddle 1703 to rotate.
