Description

Technical Field

[0001] The invention relates to the technical field of crop irrigation, in particular to a salt-alkali resistant crop irrigation and fertilization combined equipment. Background Art

[0002] Crop irrigation, that is, irrigation operations in agricultural farming areas, is a key link in ensuring the normal growth of crops. Saline-alkali land refers to a type of land that contains excessive soluble salt in the soil, resulting in decreased soil fertility and restricted crop growth. Globally, saline-alkali land is widespread, posing a serious threat to agricultural production. Planting crops on saline-alkali land not only results in low crop yields, but also often poor quality, which seriously affects the sustainability of agricultural production and food security. Therefore, cultivating salt-alkali-tolerant crops to effectively manage saline-alkali land has become an important issue in the current agricultural production field.

[0003] At present, in the process of irrigation and fertilization of salt-alkali tolerant crops, farmers generally rely on electronic equipment such as water pumps to accurately control the ratio of seawater and freshwater to nutrient solution. However, these water pump equipment integrates multiple precision components such as motors, sensors, and controllers, which not only makes the overall structure more complicated, but once a component fails, it may need to be shut down for maintenance, affecting the continuous operation of the equipment. It also correspondingly increases the technical threshold for installation and the frequency of subsequent maintenance, and increases the difficulty of operation and overall operating costs for farmers.

[0031] The main body 1 includes a cart 101, two support frames 102 are fixedly installed on the top of the cart 101, the tops of the two support frames 102 are fixedly connected to the bottoms of two storage boxes 216, a fresh water tank 103 is fixedly installed between the tops of the two support frames 102, the outer walls of the two shells 201 are fixedly inserted in the interior of the fresh water tank 103, the input end of the one-way valve 220 is fixedly connected to the output end of the fresh water tank 103, and the fresh water tank 103 is fixedly connected to the output end of the one-way valve 220. 3 is fixedly mounted with a motor 104 on the top, a rotating shaft 105 is fixedly mounted on the output end of the motor 104, and the outer wall of the rotating shaft 105 is movably inserted in the fresh water tank 103, the outer wall of the rotating shaft 105 is movably inserted in the mixing box 219, a sprocket 106 is fixedly sleeved on the outer wall of the rotating shaft 105, the outer wall of the chain 221 is movably sleeved with the outer wall of the sprocket 106, and a group of stirring paddles 107 are fixedly sleeved on the outer wall of the rotating shaft 105.

[0032] In this embodiment, when using the device, people can add fresh water, sea water and nutrient solution into the tanks through the water inlets on the top of the fresh water tank 103 and the two storage tanks 216. After the motor 104 is started, the shaft 105 can be driven to rotate inside the fresh water tank 103. At this time, the sprocket 106 on the surface of the shaft 105 rotates accordingly, and the chain 221 set on the surface of the sprocket 106 moves accordingly under the drive of the sprocket 106. The sprockets 209 at both ends of the chain 221 are driven to rotate by the chain 221, and the speed change shafts 207 inserted in the two sprockets 209 start to rotate. The speed change shafts 207 are meshed with the speed change shafts 1 204, so the speed change shafts 207 drive the speed change shafts 1 204 and the gears 2 fixedly set on the outer wall. 208 rotates, a rotating shaft 205 is movably inserted inside the speed change shaft 1 204, and a protrusion is installed on the outer wall of the rotating shaft 205 to ensure that the rotating shaft 205 can slide up and down inside the speed change shaft 1 204. When the speed change shaft 1 204 rotates, it will drive the rotating shaft 205 to rotate. At this time, the gear 1 206 fixedly sleeved on the outer wall of the rotating shaft 205 begins to rotate, and the gear 208 driven by the speed change shaft 207 will also drive the gear 208 together. The rotating gear 208 makes the gear 3 223 meshing with it rotate on the surface of the positioning rod 1 222, and the positioning rod 224 fixed at the bottom edge of the gear 3 223 starts to make a circular motion, which makes one end of the connecting frame 225 sleeved on the outer wall of the positioning rod 224 make a circular motion. The other end of the bracket 225 converts the circular motion into reciprocating linear motion, and at the same time pulls the piston 227 to move inside the liquid pumping box 217 through the connecting seat 226. When the piston 227 moves outward, the air pressure inside the liquid pumping box 217 decreases, and the corresponding seawater or nutrient solution inside the storage box 216 enters the liquid pumping box 217 through the one-way valve 220. When the piston 227 moves inward, the liquid in the liquid pumping box 217 will flow out through the one-way valve 1 218 under the action of pressure and enter the mixing box 219. At this time, the fresh water inside the fresh water tank 103 will also flow through the one-way valve 3 228 into the mixing box 219. The force required to open the one-way valve 3 228 is much smaller than that of the other two one-way valves. The installation is to prevent seawater and nutrient solution from contaminating unused fresh water. The gravity of the body is enough to open the one-way valve three 228. When the concentration of seawater and nutrient solution needs to be adjusted, the user can first turn off the motor 104, and then pull the pull rod 213 outward. At this time, the pull rod 213 can squeeze the spring one 214, driving the block 215 to be pulled out from the inside of the positioning hole 211. At this time, the user can push the speed change shaft one 204 to slide on the surface of the rotating shaft two 205. The outer walls of the speed change shaft one 204 and the speed change shaft two 207 are fixedly sleeved with three large, medium and small gears, and they cannot be meshed at the same time. When the user wants a lower concentration of seawater or nutrient solution, the large gear on the speed change shaft one 204 can be meshed with the small gear on the speed change shaft two 207. At this time, the other gears are separated from each other, the speed of the speed change shaft one 204 is reduced, and the movement speed of the piston 227 is slower.When the flow rates of other liquids remain unchanged, the corresponding flow rates of seawater or nutrient solution decrease, so that the concentration of seawater or nutrient solution in the liquid inside the mixing box 219 decreases. After the user continues to push the speed change shaft 1 204 downward, the middle gears of the two speed change shafts mesh with each other, and the other gears separate from each other. The rotation speeds of the two speed change shafts remain consistent, and the piston 227 makes the liquid flow rate medium. The concentration of seawater or nutrient solution in the mixing box 219 is also maintained at a medium level. If the speed change shaft 1 204 continues to descend, the small gear of the speed change shaft 1 204 meshes with the large gear of the speed change shaft 207, and the speed of the speed change shaft 1 204 will be greater than that of the speed change shaft 207, pushing the piston 227 to quickly move a large amount of seawater or nutrient solution into the mixing box 219. The concentration of water or nutrient solution is sent to the mixing box 219 to increase the concentration of seawater or nutrient solution in the liquid. After the position of the speed change shaft 204 is determined, as the user lets go, the squeezed spring 214 drives the block 215 to insert into the positioning hole 211 to fix the position of the speed change shaft 204. The device adopts part of the principle of the gearbox, which is convenient for users to quickly adjust the concentration of seawater or nutrient solution in the irrigation water through manual operation. The device uses the motor 104 as the only power source, which reduces power consumption, which helps to reduce agricultural production costs and reduce dependence on energy. The operation and maintenance of the equipment will become simpler and reduce the skill requirements for the operator.

[0033] Embodiment 2: According to Figure 1 - Figure 7 As shown, the main body mechanism 1 includes a cart 101, two support frames 102 are fixedly installed on the top of the cart 101, the tops of the two support frames 102 are fixedly connected to the bottoms of two storage boxes 216, a fresh water tank 103 is fixedly installed between the tops of the two support frames 102, the outer walls of the two shells 201 are fixedly inserted into the interior of the fresh water tank 103, the input end of the one-way valve 220 is fixedly connected to the output end of the fresh water tank 103, and the fresh water tank 1 A motor 104 is fixedly installed on the top of 03, and a rotating shaft 105 is fixedly installed on the output end of the motor 104, and the outer wall of the rotating shaft 105 is movably inserted in the interior of the fresh water tank 103, and the outer wall of the rotating shaft 105 is movably inserted in the interior of the mixing box 219, and a sprocket 106 is fixedly sleeved on the outer wall of the rotating shaft 105, and the outer wall of the chain 221 is movably sleeved with the outer wall of the sprocket 106, and a group of stirring paddles 107 are fixedly sleeved on the outer wall of the rotating shaft 105.

[0034] In this embodiment, the cart 101 can make the equipment easily move between different fields without consuming a lot of manpower for transportation, thereby reducing the fatigue caused by long-term transportation. After the motor 104 is started, it will drive the rotating shaft 105 to start rotating. At this time, a group of stirring paddles 107 fixedly installed on the outer wall of the rotating shaft 105 will rotate inside the mixing box 219, so that the seawater, fresh water and nutrient solution can be fully mixed, and the uniform mixture can be more effectively absorbed and utilized by crops, thereby improving the effect of irrigation and fertilization and reducing the loss and waste of fertilizer and water resources.

[0035] Embodiment 3: According to Figure 1 as well as Figure 7 As shown, the spraying mechanism 3 includes two cylinders 301, the input ends of the two cylinders 301 are fixedly connected to the output end of the mixing box 219, the outer walls of the two cylinders 301 are fixedly sleeved with a group of support seats 302, the bottoms of the two groups of support seats 302 are fixedly connected to the top of the cart 101, the inner walls of the two cylinders 301 are movably inserted with spray pipes 1 303, one side of the outer wall of the two spray pipes 1 303 is fixedly installed with springs 2 304, and one side of the outer walls of the two springs 2 304 is fixedly connected to one side of the inner wall of the cylinder 301, one side of the inner wall of the two spray pipes 1 303 is fixedly installed with springs 305, one side of the outer walls of the two springs 305 is fixedly installed with spray pipes 2 306, and the outer walls of the two spray pipes 2 306 are movably inserted into the inside of the spray pipe 1 303.

[0036] In this embodiment, after the mixed irrigation water enters the cylinder 301, the impact force of the water flow will push the spray pipe 2 306 to squeeze the spring 305 and extend it from the inside of the spray pipe 1 303. When the spring 305 can no longer be compressed, it will drive the spray pipe 1 303 to move forward together, so that the spray pipe 1 303 squeezes the spring 2 304 and extends it from the inside of the cylinder 301. The irrigation water can be sprayed out from the holes at the bottom of the spray pipe 1 303 and the spray pipe 2 306. The two spray pipes can be stretched under the impact of the water flow, thereby increasing the coverage area of ​​the irrigation equipment. In one irrigation operation, more rice field areas can be covered, and the irrigation efficiency is also improved. The two spray pipes are driven to move by the water flow. After the irrigation is completed, the two squeezed springs begin to stretch, pushing the spray pipe to retract into the cylinder 301. The entire operation does not require manual processing, which significantly reduces manual intervention in the irrigation and fertilization process, and greatly saves time and labor costs.

[0037] The working principle of the whole mechanism is as follows: the cart 101 facilitates the movement of the salt-alkali resistant irrigation and fertilization equipment for crops, so that it can be easily moved between different fields. When using the equipment, the user only needs to simply add fresh water, sea water and nutrient solution through the water inlets on the top of the fresh water tank 103 and the two storage tanks 216. Once the motor 104 is started, it will drive the rotating shaft 105 to rotate, and then drive the sprocket 106 and the chain 221 to move. This movement process will in turn drive the rotation of the sprocket 209, the speed change shaft 207, the speed change shaft 1 204 and the gear 2 208, so that the rotating shaft 205 inside the speed change shaft 1 204 will also rotate, and the gear 1 206 on its outer wall drives the gear 3 223 to rotate, and the gear 3 22 The positioning rod 224 at the bottom of the pumping box 217 performs a circular motion, and the motion is converted into a reciprocating linear motion through the connecting frame 225, thereby pulling the piston 227 to move in the pumping box 217. The reciprocating motion of the piston 227 realizes the automatic extraction and mixing of seawater, nutrient solution and fresh water. When the piston 227 moves outward, the air pressure inside the pumping box 217 decreases, and the seawater or nutrient solution is sucked in through the one-way valve 220. When the piston 227 moves inward, the liquid in the pumping box 217 flows out through the one-way valve 1 218 under pressure and enters the mixing box 219. At the same time, the fresh water in the fresh water tank 103 also flows into the mixing box 219 through the one-way valve 3 228. The design of the one-way valve 3 228 ensures that the fresh water will not be contaminated by seawater and nutrient solution, and the user It is only necessary to turn off the motor 104, pull the pull rod 213, squeeze the spring 1 214, and pull the block 215 out of the positioning hole 211, and then push the speed change shaft 1 204 to slide on the surface of the rotating shaft 2 205, and select a suitable gear meshing mode. The meshing of the large gear and the small gear will reduce the movement speed of the piston 227, thereby reducing the flow rate of the corresponding liquid, so that the concentration of seawater or nutrient solution in the liquid inside the mixing box 219 is reduced, and the meshing of the medium gear maintains a medium flow rate and concentration. The meshing of the small gear and the large gear will increase the movement speed of the piston 227, increase the flow rate of the corresponding liquid, and increase the concentration of seawater or nutrient solution in the liquid inside the mixing box 219. The device uses the motor 104 as the only power source, which reduces power consumption and energy dependence. The operation and maintenance process of the equipment is simplified. A group of stirring paddles 107 are fixedly installed on the outer wall of the rotating shaft 105. These stirring paddles 107 rotate inside the mixing box 219 as the rotating shaft 105 rotates, effectively mixing the seawater, fresh water and nutrient solution, and improving the effect of irrigation and fertilization. When the evenly mixed irrigation water flows into the cylinder 301, its strong impact force will push the spray pipe 2 306 to squeeze the spring 305 and cause the spray pipe 2 306 to extend from the inside of the spray pipe 1 303. As the compression of the spring 305 reaches the limit, it will further drive the spray pipe 1 303 to move forward. At the same time, the spray pipe 1 303 will also squeeze the spring 2 304 and extend from the cylinder 301. At this time,Irrigation water can be evenly sprayed through the spray holes at the bottom of the spray pipe 1 303 and the spray pipe 2 306, so that the two spray pipes can automatically extend under the impact of the water flow, thereby increasing the coverage area of ​​the irrigation equipment and making the irrigation operation more convenient and efficient. After the irrigation is completed, the compressed spring 2 304 and spring 305 will automatically extend to push the spray pipe 1 303 and the spray pipe 2 306 back into the cylinder 301 to prepare for the next irrigation operation.
