Description

Technical Field

[0001] The invention relates to the technical field of soil remediation devices, and in particular to a liquid improver uniformly spreading device for improving saline-alkali land. Background Art

[0002] Saline-alkali land refers to soil with high salt or alkalinity content, which cannot be used to grow crops directly, wasting a lot of land resources. In order to make full use of resources, it is necessary to improve saline-alkali land with high salt and alkalinity content. There are many ways to improve it, such as water conservancy improvement, agricultural technology improvement, biological improvement and chemical improvement. Each improvement method has many steps, and agricultural technology improvement requires spraying improvers on the land. Therefore, the improver uniformly spreading device is a common equipment in saline-alkali land improvement.

[0003] For example, a Chinese patent with publication number CN219961300U discloses a saline-alkali land soil conditioner spraying device, which reduces the evaporation of the soil conditioner, allows the soil conditioner to fully contact the soil, has a good soil improvement effect, and is highly practical; it includes a mobile vehicle, a spray pipe and multiple groups of nozzles, the spray pipe is fixedly installed on the mobile vehicle, the multiple groups of nozzles are all installed on the spray pipe, and the multiple groups of nozzles are all connected to the spray pipe; it also includes a fixed plate, two groups of connecting plates, a motor, a roller, a lifting device, a storage device and a conveying device, the fixed plate is installed on the left side of the mobile vehicle through the lifting device, the lifting device is used to lift the fixed plate, the two groups of connecting plates are fixedly installed at the lower end of the fixed plate, the motor is fixedly installed on the front connecting plate, the roller is rotatably installed on the two groups of connecting plates, and the front end of the roller is connected to the output end of the motor.

[0004] Although the above patent can improve the saline-alkali soil, the spraying amount of the multiple groups of nozzles when spraying the improver solution is fixed, and the soil properties at different locations in the field may be different, such as salt content, pH value, organic matter content, etc. These factors will directly affect the formation and distribution of saline-alkali land, resulting in higher soil salt content and more water loss in some areas of the field, resulting in drier and harder soil. Spraying the improver solution with the same standard will result in poor improvement effect on some soils with higher salt content, affecting the subsequent growth of crops. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a liquid improver uniformly spreading device for improving saline-alkali land, so as to solve the problems existing in the above-mentioned background technology.

[0006] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

The same rotating box, the fixed medicine box and the corresponding rotating box are arranged in abutment with each other, a sled is arranged on the bottom side of the rotating box, a fixed column is arranged on the top of the rotating box, a mounting frame is arranged on the end of the support frame away from the connecting frame, a spring is connected between the mounting frame and the fixed column, the sides of the fixed medicine box abutting against the rotating box are provided with through holes, the through holes on the rotating box and the fixed medicine box are staggered, and the through holes on the side of the rotating box can overlap with the through holes on the side of the fixed medicine box when the rotating box rotates, and a spray hole is arranged at the bottom of the rotating box.

[0008] Preferably, a sealing layer is provided on the side where the rotating box abuts against the fixed medicine box, and the sealing layer is made of polytetrafluoroethylene.

[0009] Preferably, an opening is provided on the top of the medicine box, a box cover is installed at the opening, an air inlet is provided on the box cover, and a filter is installed at the air inlet.

[0010] Preferably, through holes are provided in the middle of the rotating box and the fixed medicine box, the rotating box is made of metal, and the through hole in the middle of the rotating box is connected to the mounting rod through a bearing.

[0011] Preferably, limit rings are provided on the mounting rods on the opposite sides of the rotating box and the fixed medicine box.

[0012] Preferably, a plurality of threaded sections are arranged at intervals on the mounting rod, and matching limiting nuts are installed on the threaded sections.

[0013] Preferably, the mounting rod is detachably connected to the mounting groove, the spring is detachably connected to the fixing column, and the spring is detachably connected to the mounting frame.

[0014] The beneficial effects of the embodiments of the present invention are:

[0015] 1. When the sledge in the device turns over the saline-alkali land, since the sledge is installed on the bottom side of the rotating box, and the rotating box can rotate on the rotating rod inside the mounting groove, and the top of the rotating box is connected to the mounting frame through a spring, when the sledge turns over the soil of the saline-alkali land, the sledge will be subjected to a reverse force, driving the rotating box to rotate on the mounting rod. Since the fixed column at the top of the rotating box is connected to the mounting frame through a spring, the reaction force on the sledge can be offset, thereby preventing the rotating box from rotating at an excessive angle and ensuring that the rotating box is in a stable state. The sled can maintain a certain rotation angle when turning the ground. Since the sides where the fixed medicine box and the rotating box are in contact are provided with through holes, and when the soil in the saline-alkali land is not turned over, the through holes on the fixed medicine box and the rotating box can be staggered. When the sled turns the soil, the sled will be subjected to the reaction force of the soil, and the sled will drive the rotating box to rotate, so that the through holes on the side of the fixed medicine box gradually overlap with the through holes on the side of the rotating box. When the salt content in the saline-alkali land is high, the water loss is large, resulting in drier soil here. The more the soil is hard, the greater the reaction force of the soil on the sled will be, causing the rotating box to rotate at a larger angle. At this time, the degree of overlap between the through holes on the side of the rotating box and the through holes on the side of the fixed agent box will be greater, and the improver inside the fixed agent box will enter the rotating box in large quantities, causing the internal pressure to be too high. The more improver sprayed out from the corresponding spray holes on the bottom of the rotating box, the more improver can be applied to the soil at this location. When the salt content of the rest of the soil is low and the water loss is less, the soil here is looser, and its reaction force on the sled will become smaller. Under the action of the spring, the rotation angle of the rotating box will become smaller. At this time, the degree of overlap between the through holes on the side of the rotating box and the through holes on the side of the fixed agent box will become smaller, and a small amount of the improver inside the fixed agent box will enter the interior of the rotating box, while the improver sprayed out of the corresponding spray hole on the bottom side of the rotating box will be reduced, so that the device can apply an appropriate amount of improver according to the different salt-alkali content of the same plot of land, so that the device can achieve a uniform sprinkling effect, avoid waste of improver, and further improve the efficiency of spraying the improver, ensuring that the saline-alkali land can be effectively improved.

[0016] 2. The sealing layer of the device can effectively prevent the improver from leaking from between the rotating box and the fixed medicine box, and the sealing layer made of polytetrafluoroethylene can ensure the sealing effect while avoiding the relative friction between the rotating box and the fixed medicine box, which leads to a reduction in their service life, thereby ensuring the service life of the device.

[0017] 3. The device can achieve the balance of the internal and external pressures of the medicine box by opening an air inlet hole on the box cover, and the filter screen arranged at the air inlet hole can prevent external foreign matter from entering the interior of the medicine box, thereby ensuring the practicality of the device.

[0018] 4. The rotating box and the fixed medicine box of the device are both installed on the mounting rod through the through hole in the middle. Limiting rings are provided on the corresponding sides of the rotating box and the fixed medicine box facing each other, which can ensure that the rotating box and the fixed medicine box abut against each other. The rotating box is installed on the mounting rod through a bearing. Since the limiting rings on both sides press on the fixed medicine box and the bearing respectively, it can ensure that the fixed medicine box is in a relatively fixed position. Since the rotating box needs to withstand the reaction force when the sled turns the ground and the force of the spring pulling the fixed column, the rotating box is made of metal material to ensure the service life of the device.

[0019] 5. The device arranges a plurality of threaded sections at intervals on the mounting rod, sleeves a rotating box and a fixed medicine box on the mounting rod between adjacent threaded sections, and then limits the positions of the fixed medicine box and the rotating box by screwing the limit nut. At the same time, it is convenient for quick installation and disassembly in case of a fault, thereby improving the maintenance efficiency of the device.

[0020] 6. By providing detachable connections between the components of the device, when the device fails or is damaged, the mounting rod can be quickly removed from the mounting slot, making it easy to replace or repair each component individually, thereby reducing the maintenance and use costs of the device.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] A liquid improver uniformly spreading device for improving saline-alkali land, such as Figure 1-Figure 5 As shown, it includes a support frame 1, a medicine box 4 is arranged on the top of the support frame 1, a connecting frame 16 is arranged at the front end of the support frame 1, a mounting groove 2 is opened at the rear end of the support frame 1, a mounting rod 3 is arranged in the mounting groove 2, and a plurality of fixed medicine boxes 10 are arranged at intervals on the mounting rod 3, a water pump 6 is arranged on the support frame 1 between the medicine box 4 and the mounting groove 2, a main pipeline 5 is connected between one end of the water pump 6 and the medicine box 4, and the other end of the water pump 6 is connected to the plurality of fixed medicine boxes 10 through a liquid dispensing tube 7, and the mounting rod 3 is provided with the same number of rotating boxes 12 as the fixed medicine boxes 10. The medicine box 10 and the corresponding rotating box 12 are arranged in abutment with each other, a sled 11 is arranged on the bottom side of the rotating box 12, a fixed column 14 is arranged on the top of the rotating box 12, a mounting frame 8 is arranged on the end of the support frame 1 away from the connecting frame 16, a spring 9 is connected between the mounting frame 8 and the fixed column 14, and the sides where the fixed medicine box 10 and the rotating box 12 are abutted are provided with through holes, and the through holes on the rotating box 12 and the fixed medicine box 10 are staggered, and when the rotating box 12 rotates, the through holes on the side of the rotating box 12 can overlap with the through holes on the side of the fixed medicine box 10, and a spray hole 13 is arranged at the bottom of the rotating box 12.

[0031] When the device is used, it can be installed on a self-propelled power mechanical equipment such as a tractor through the connecting frame 16 at the front end of the supporting frame 1. The existing tractors are all provided with a lifting device (the lifting device on the tractor is a prior art and will not be described in detail here). Under the drive of the lifting device, the bottom end of the sled 11 at the bottom side of the rotating box 12 in the mounting groove 2 can be inserted into the soil. Then, under the drive of the tractor, the device is driven to turn over the soil in the saline-alkali land, break the plow bottom layer, loosen the soil, and increase the air permeability and permeability of the soil. When the tractor is working, the water pump 6 works synchronously to turn the inside of the medicine box 4. The improver is transported to the interior of a plurality of fixed medicine boxes 10 through the main pipeline 5 and the dispensing pipe 7. Due to the drive of the tractor, the sledge 11 turns over the saline-alkali land. Since the sledge 11 is installed on the bottom side of the rotating box 12, and the rotating box 12 can rotate on the rotating rod inside the mounting groove 2, and the top of the rotating box 12 is connected to the mounting frame 8 through the spring 9, when the sledge 11 turns over the soil of the saline-alkali land, the sledge 11 will be subjected to a reverse force, driving the rotating box 12 to rotate on the mounting rod 3. Since the fixed column 14 at the top of the rotating box 12 is connected to the mounting frame 8 through the spring 9 The sled 11 is connected to the ground, so it can offset the reaction force received by the sled 11, avoid the rotating box 12 from rotating too much, and ensure that the rotating box 12 can maintain a certain rotation angle when the sled 11 turns the ground. Since the sides where the fixed medicine box 10 and the rotating box 12 abut against each other are provided with through holes, and when the soil in the saline-alkali land is not turned over, the through holes on the fixed medicine box 10 and the rotating box 12 can be staggered. When the sled 11 turns the soil, the sled 11 will be subjected to the reaction force of the soil, and the sled 11 will drive the rotating box 12 to rotate, so that the through holes on the side of the fixed medicine box 10 The holes on the side of the rotating box 12 gradually overlap with each other. When the salt content in the saline-alkali soil is high and the water loss is large, the soil here is relatively dry and hard. The reaction force of the soil on the sled 11 is large, causing the rotating box 12 to rotate at a larger angle. At this time, the holes on the side of the rotating box 12 overlap with the holes on the side of the fixed medicine box 10 to a greater extent, and the improver in the fixed medicine box 10 will enter the rotating box 12 in large quantities, causing the internal pressure to be too high. The more improver is sprayed out from the spray holes 13 on the bottom side of the corresponding rotating box 12, the more improver can be applied to the soil there.

[0032] When the salt content of the rest of the soil is low and the water loss is less, the soil here is looser and its reaction force on the sled 11 will become smaller. Under the action of the spring 9, the rotation angle of the rotating box 12 will become smaller. At this time, the overlap degree of the through holes on the side of the rotating box 12 and the through holes on the side of the fixed medicine box 10 will become smaller, and the improver inside the fixed medicine box 10 will enter the rotating box 12 in small quantities, while the improver sprayed out of the spray hole 13 on the bottom side of the corresponding rotating box 12 is reduced, so that the device can apply an appropriate amount of improver according to the different salt-alkali content of the same plot, so that the device can achieve a uniform sprinkling effect, avoid waste of improver, and further improve the efficiency of spraying the improver, ensuring that the saline-alkali land can be effectively improved.

[0033] A sealing layer is provided on the side where the rotating box 12 abuts against the fixed medicine box 10 , and the sealing layer is made of polytetrafluoroethylene.

[0034] By setting up a sealing layer, the improver can be effectively prevented from leaking from between the rotating box 12 and the fixed medicine box 10. The sealing layer made of polytetrafluoroethylene material can ensure the sealing effect while avoiding the relative friction between the rotating box 12 and the fixed medicine box 10, which leads to a reduction in their service life, thereby ensuring the service life of the device.

[0035] The top of the medicine box 4 is provided with an opening, a box cover 15 is installed at the opening, an air inlet is provided on the box cover 15, and a filter is installed at the air inlet.

[0036] The operator can inject sufficient improver into the medicine box 4 through the opening on the top of the medicine box 4, and seal the opening with the box cover 15 to prevent external foreign matter from entering the medicine box 4 when the soil is turned over, and when the water pump 6 is working, the improver inside the medicine box 4 will be sucked, resulting in negative pressure inside the medicine box 4. By opening an air inlet hole on the box cover 15, the balance of pressure inside and outside the medicine box 4 can be achieved, and the filter net arranged at the air inlet hole can isolate external foreign matter from entering the medicine box 4, thereby ensuring the practicality of the device.

[0037] The rotating box 12 and the fixed medicine box 10 are both provided with through holes in the middle. The rotating box 12 is made of metal material. The through hole in the middle of the rotating box 12 is connected to the mounting rod 3 through a bearing. The mounting rod 3 on the side facing the rotating box 12 and the fixed medicine box 10 is provided with a limit ring.

[0038] The rotating box 12 and the fixed medicine box 10 are both installed on the mounting rod 3 through the through hole in the middle. Limiting rings are provided on the corresponding sides of the rotating box 12 and the fixed medicine box 10 facing each other, which can ensure that the rotating box 12 and the fixed medicine box 10 abut against each other. The rotating box 12 is installed on the mounting rod 3 through bearings. Since the limiting rings on both sides press on the fixed medicine box 10 and the bearings respectively, it can ensure that the fixed medicine box 10 is in a relatively fixed position. Since the rotating box 12 needs to withstand the reaction force of the sled 11 when turning the ground and the force of the spring 9 pulling the fixed column 14, the rotating box 12 is made of metal material to ensure the service life of the device.

[0039] Embodiment 2

[0040] Based on the first embodiment, Figure 6 As shown, a plurality of threaded sections are arranged at intervals on the installation rod 3, and matching limiting nuts 17 are installed on the threaded sections.

[0041] By arranging a plurality of threaded sections at intervals on the mounting rod 3, sleeved the rotating box 12 and the fixed medicine box 10 on the mounting rod 3 between the adjacent threaded sections, and then screwing the limiting nut 17, the positions of the fixed medicine box 10 and the rotating box 12 can be limited by the limiting nut 17, and at the same time, it is convenient for rapid installation and disassembly when a fault occurs, thereby improving the maintenance efficiency of the device.

[0042] The mounting rod 3 is detachably connected to the mounting groove 2 , the spring 9 is detachably connected to the fixing column 14 , and the spring 9 is detachably connected to the mounting bracket 8 .

[0043] When the device fails or is damaged, the mounting rod 3 can be quickly removed from the mounting slot 2, so that each component can be replaced or repaired individually, thereby reducing the maintenance and use costs of the device.
