Description

Technical Field

[0001] This utility model relates to the field of acid soil improvement technology, specifically to a device for uniformly spreading alkaline materials for acid soil improvement. Background Technology

[0002] Acid soil improvement refers to the process of reducing soil acidity, improving soil physical and chemical properties, and enhancing soil fertility and suitability through a series of technologies and measures to create a favorable environment for plant growth. Applying alkaline substances is the most direct method for improving acid soil. Common alkaline materials include lime, wood ash, calcium magnesium phosphate fertilizer, etc. In the process of acid soil improvement, evenly spreading alkaline materials into the soil is a common and effective improvement method.

[0003] However, existing spreading devices still have certain problems in use:

[0004] An agricultural spreading device, such as one described in application number CN201922425457.8, includes a fertilizer box with supporting legs at its bottom and wheels mounted on the supporting legs; a first discharge port and a second discharge port at the bottom of the fertilizer box; a support frame located on top of the fertilizer box, comprising two first support plates and a second support plate; a stirring device including a motor, a first stirring shaft, and a second stirring shaft; both the first and second stirring shafts being located inside the fertilizer box, and having stirring blades on them; and two receiving pipes connected to the first and second discharge ports respectively, with a spreading head connected to the end of each receiving pipe away from the fertilizer box, and the spreading head having a discharge hole.

[0005] Traditional spreading equipment only has basic material conveying functions and lacks the ability to break up and clump materials, which makes alkaline materials prone to clogging the discharge port during spreading, affecting the continuity of operations. On the other hand, the equipment cannot achieve quantitative spreading and cannot dynamically adjust the spreading amount according to the difference in soil pH, resulting in waste of resources or poor improvement effect.

[0006] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0007] To address the aforementioned issues, an innovative design was developed based on the existing spreading device. Utility Model Content

[0008] The purpose of this invention is to provide a device for uniformly spreading alkaline materials for improving acidic soil, in order to solve the problems mentioned in the background art. On the one hand, the spreading equipment only has basic material conveying functions and lacks the treatment of material crushing and agglomeration, which makes the alkaline materials easy to block the discharge port during the spreading process, affecting the continuity of operation. On the other hand, the equipment cannot achieve quantitative spreading and cannot dynamically adjust the spreading amount according to the difference in soil pH, resulting in resource waste or poor improvement effect.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A device for uniformly spreading alkaline materials for improving acidic soil includes a vehicle body and a hopper. The hopper is welded to the middle of the vehicle body. A feed inlet is installed on the upper end face of the hopper. A drive motor is installed on the upper end face of the hopper. The output end of the drive motor is movably connected to a drive shaft, which extends into the hopper and is rotatably connected to the hopper via a bearing. An upper fixing rod is welded to the outer surface of the upper section of the drive shaft, and a lower fixing rod is welded to the outer surface of the lower section of the drive shaft. A stirring shaft is installed between the upper and lower fixing rods. A stirring blade is installed at the bottom end of the drive shaft. A discharge plate is installed at the discharge port of the hopper. A connecting shaft is fixed to the bottom end of the drive shaft, and the bottom end of the connecting shaft is rotatably connected to the discharge plate via a bearing. A pusher plate is fixed to the outer surface of the connecting shaft.

[0011] Using the above technical solution, the drive motor drives the drive shaft to rotate, causing the stirring shaft and stirring blades to rotate and stir the alkaline material in the hopper to prevent clumping. At the same time, the connecting shaft drives the pusher plate to rotate at the discharge plate, pushing the material to be discharged evenly. The stirring structure ensures the fluidity of the material and avoids blockage. Together with the pusher plate, it realizes the continuous and uniform spreading of alkaline materials, improving the effect of acid soil improvement.

[0012] Preferably, a hinge is installed on the outside of the feed inlet, and a cover plate is rotatably connected above the feed inlet via the hinge. A rubber sealing plate is adhered to the inner end face of the cover plate.

[0013] By adopting the above technical solution, the cover plate and the feed inlet are rotated and connected by a hinge. The elastic deformation of the rubber sealing plate fills the gap between the cover plate and the feed inlet, forming a sealing structure to prevent external rainwater and dust from entering the hopper and contaminating the material. At the same time, it avoids the volatilization or moisture-induced clumping of alkaline materials, ensuring the stability of equipment operation and the quality of materials.

[0014] Preferably, the upper and lower fixing rods are symmetrically arranged in two sets along the outer surface of the drive shaft, and the stirring shaft is arranged in five sets laterally between the upper and lower fixing rods.

[0015] Using the above technical solution, the drive shaft drives the symmetrically distributed fixed rods to rotate, so that multiple sets of horizontally arranged stirring shafts form a three-dimensional stirring zone. The multi-axis cross motion enhances the shearing and tumbling effect of materials, effectively breaks up alkaline material agglomeration, improves the mixing uniformity, expands the stirring coverage area, prevents the formation of stirring dead corners in the hopper, and ensures that the materials continue to maintain a loose and flowing state.

[0016] Preferably, two sets of stirring blades are fixedly installed at the bottom end of the drive shaft, and the stirring blades consist of three blades.

[0017] Using the above technical solution, the drive shaft drives the two sets of three-blade stirring blades at the bottom to rotate synchronously. By utilizing the spiral angle and centrifugal force of the blades, a material surging flow field is formed from bottom to top, which thoroughly disperses the alkaline material deposited at the bottom of the hopper and prevents the discharge port from being blocked. At the same time, the three-dimensional stirring action ensures the overall uniformity of the material and improves the smoothness of the discharge.

[0018] Preferably, the feeding plates are fan-shaped and arranged in two symmetrical groups, with a discharge hole between the two groups of feeding plates. The pusher plates are fan-shaped and arranged in four groups around the outer surface of the connecting shaft, with a feeding groove between the four groups of pusher plates.

[0019] Using the above technical solution, the drive shaft drives the annularly distributed fan-shaped pusher plates to rotate, so that the material is periodically pushed through the feeding trough to the discharge hole between the two sets of fan-shaped feeding plates. The flow uniformity is controlled by intermittent feeding. The fan-shaped feeding plates and the pusher plates work together to form an adjustable discharge channel, which not only prevents material accumulation and blockage, but also ensures that alkaline materials are continuously spread at the set rate, thus improving the fertilization accuracy.

[0020] Preferably, a controller is installed on the top of the vehicle body, a display screen is installed on the outer surface of the controller, and a camera is installed on the bottom of the vehicle body.

[0021] Using the above technical solution, the controller receives ground image information collected by the camera and provides real-time feedback on operating parameters and work status through the display screen, achieving precise positioning and seeding path planning. The display screen also intuitively displays equipment operating data, helping operators adjust work parameters in real time and improving the level of intelligence.

[0022] Preferably, a handle is welded to the top of the vehicle body, and the outer surface of the handle is covered with a sponge material grip.

[0023] The above technical solution provides a stable force application point through an ergonomically designed handle, a sponge grip that uses elastic deformation to distribute hand pressure and increase friction to prevent slippage, a welded handle to ensure structural stability during operation, and a sponge covering layer to improve comfort during long-term operation, reduce operator hand fatigue, and enhance the flexibility of equipment operation.

[0024] Compared with the prior art, the beneficial effects of this utility model are: the alkaline material uniform spreading device for acidic soil improvement,

[0025] 1. The drive motor drives the drive shaft to rotate, forming a three-dimensional mixing system with the upper and lower fixed rods and multiple sets of mixing shafts in between. This effectively breaks up lumps of alkaline materials that are generated during storage or transportation, preventing large pieces of material from clogging the discharge port. At the same time, the mixing blades at the bottom of the drive shaft can tumble the material deposited at the bottom of the hopper, ensuring uniform overall material flow and thus providing a foundation for stable subsequent feeding, improving the continuity and reliability of the spreading operation.

[0026] 2. The hopper discharge port adopts a combination design of a feeding plate and a pusher plate. The drive shaft drives the pusher plate to rotate through the connecting shaft, so that the material is periodically pushed through the feeding groove between the pusher plates to the discharge hole of the feeding plate. The continuous scraping of the pusher plate prevents the material from accumulating and blocking, and the size matching between the feeding plate and the discharge hole precisely controls the feeding amount per unit time. This realizes the quantitative and uniform spreading of alkaline materials, effectively improving the fertilization accuracy and resource utilization rate of acid soil improvement operations.

[0027] 3. The cover plate and the feed inlet are rotated and connected by hinges. The elastic deformation of the rubber sealing plate fills the gap between the cover plate and the feed inlet, forming a sealing structure to prevent external rainwater and dust from entering the hopper and contaminating the material. At the same time, it prevents alkaline materials from volatilizing or becoming damp and clumping, ensuring the stability of equipment operation and material quality.

[0028] 4. The controller receives ground image information collected by the camera and provides real-time feedback on operating parameters and work status through the display screen, enabling precise positioning and seeding path planning. The display screen also intuitively displays equipment operating data, helping operators to adjust work parameters in real time and improving the level of intelligence.

[0029] 5. The ergonomically designed handle provides a stable point of force application, the sponge grip uses elastic deformation to distribute hand pressure and increase friction to prevent slippage, the welded handle ensures structural stability during operation, and the sponge covering layer improves comfort during long-term operation, reduces operator hand fatigue, and enhances the flexibility of equipment operation.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 This utility model provides a technical solution:

[0039] A device for uniformly spreading alkaline materials for improving acidic soil includes a vehicle body 1 and a hopper 7. The hopper 7 is welded to the middle of the vehicle body 1. A feed inlet 8 is installed on the upper end face of the hopper 7. A drive motor 12 is installed on the upper end face of the hopper 7. A drive shaft 13 is movably connected to the output end of the drive motor 12, and the drive shaft 13 extends into the interior of the hopper 7 and is rotatably connected to the hopper 7 via bearings. An upper fixing rod 14 is welded to the outer surface of the upper section of the drive shaft 13, and a lower fixing rod 15 is welded to the outer surface of the lower section of the drive shaft 13. A stirring shaft 16 is installed between the upper fixing rod 14 and the lower fixing rod 15. A stirring blade 17 is installed at the bottom end of the drive shaft 13. A hinge 9 is installed on the outside of the feed inlet 8, and a cover plate 10 is rotatably connected to the top of the feed inlet 8 via the hinge 9. A rubber sealing plate 11 is adhered to the inner end face of the cover plate 10. Two sets of upper fixed rods 14 and lower fixed rods 15 are symmetrically arranged along the outer surface of the drive shaft 13, and five sets of stirring shafts 16 are arranged laterally between the upper fixed rods 14 and lower fixed rods 15. Two sets of stirring blades 17 are fixedly installed at the bottom end of the drive shaft 13, and each stirring blade 17 consists of three blades.

[0040] This alkaline material uniform spreading device for acidic soil improvement uses a vehicle body 1 to support the overall structure. Inside the hopper 7, a drive motor 12 drives the drive shaft 13 to rotate, which in turn rotates two symmetrically distributed upper fixed rods 14 and lower fixed rods 15. This causes the five horizontally arranged stirring shafts 16 to form a three-dimensional stirring zone, effectively breaking up clumps of alkaline materials. At the bottom of the drive shaft 13, two sets of three-bladed stirring blades 17 generate centrifugal force through a spiral angle design, further agitating the bottom sediment and ensuring fluidity. The feed inlet 8 uses a cover plate 10 connected by a hinge 9, which, together with a rubber sealing plate 11, achieves dustproof and moisture-proof sealing, ensuring uniform mixing of materials and preventing blockages, while also preventing external contamination. Finally, the drive shaft 13 is linked to achieve efficient and stable spreading of alkaline materials.

[0041] Example 2

[0042] Please see Figure 2 , Figure 4 This utility model provides a technical solution:

[0043] A discharge plate 18 is installed at the discharge port of the hopper 7. A connecting shaft 20 is fixed to the bottom end of the drive shaft 13, and the bottom end of the connecting shaft 20 is rotatably connected to the discharge plate 18 through a bearing. A pusher plate 21 is fixed to the outer surface of the connecting shaft 20. The discharge plates 18 have a fan-shaped structure and are arranged in two symmetrical groups. A discharge hole 19 is provided between the two groups of discharge plates 18. The pusher plates 21 have a fan-shaped structure and are arranged in four groups in a ring along the outer surface of the connecting shaft 20. A discharge groove 22 is provided between the four groups of pusher plates 21.

[0044] This alkaline material uniform spreading device for acid soil improvement uses a drive shaft 13 at the discharge port of the hopper 7. The drive shaft 13, via a connecting shaft 20 fixed at the bottom, drives four sets of annularly distributed fan-shaped pusher plates 21 to rotate synchronously. The feeding troughs 22 between the pusher plates 21 periodically push the material to the discharge holes 19 between two sets of symmetrical fan-shaped feeding plates 18. The centrifugal force generated by the rotation of the pusher plates 21 and the fan-shaped opening angle of the feeding plates 18 form a controllable material channel. This not only prevents material accumulation and blockage at the discharge port through continuous scraping by the pusher plates 21, but also precisely adjusts the feeding amount per unit time by matching the dimensions of the feeding plates 18 and the discharge holes 19. Ultimately, this achieves uniform spreading of alkaline materials at a set rate, ensuring the stability and fertilization accuracy of acid soil improvement operations.

[0045] Example 3

[0046] Please see Figure 1 This utility model provides a technical solution:

[0047] A controller 2 is installed on the top of the vehicle body 1, and a display screen 3 is installed on the outer surface of the controller 2. A camera 4 is installed on the bottom of the vehicle body 1. A handle 5 is welded to the top of the vehicle body 1, and the outer surface of the handle 5 is covered with a sponge grip 6.

[0048] This alkaline material uniform spreading device for acidic soil improvement incorporates a controller 2 as the core control unit within the intelligent and user-friendly design of the vehicle body 1. This controller integrates ground image data collected by the camera 4 via a built-in program, analyzes soil conditions or spreading trajectory in real time, and displays operational parameters such as feeding rate and remaining material quantity on the screen 3, assisting operators in precise control. The camera 4 at the bottom of the vehicle body 1 provides visual monitoring, identifying soil pH distribution or spreading coverage, providing decision-making basis for the controller 2. The handle 5 welded to the top of the vehicle body 1 features an ergonomic design to ensure operational stability. Its sponge-material grip 6 utilizes elastic deformation to distribute hand pressure, improving comfort during extended operation while enhancing friction to prevent slippage, ultimately achieving both high efficiency and user-friendliness in equipment operation.

[0049] Working principle:

[0050] When this utility model is in operation, the vehicle body 1 carries the overall structure. The drive motor 12 inside the hopper 7 drives the drive shaft 13 to rotate, which drives two sets of symmetrically distributed upper fixed rods 14, lower fixed rods 15 and five sets of transverse stirring shafts 16 to form a three-dimensional stirring area to break up material lumps. At the same time, two sets of three-bladed stirring blades 17 at the bottom of the drive shaft 13 tumble the bottom material through a spiral angle to ensure fluidity. At the discharge port, the drive shaft 13 drives four sets of annular pusher plates 21 to rotate through the connecting shaft 20. The discharge hole 19 between the discharge trough 22 and the fan-shaped discharge plate 18 forms a controllable channel to achieve precise material feeding. The controller 2 above the vehicle body 1 integrates the soil image data collected by the bottom camera 4, displays the operating parameters on the display screen 3 and assists in the adjustment. With the ergonomic design of the welded handle 5 and the sponge grip 6, the efficient and uniform spreading of alkaline materials is finally completed through the synergy of mechanical stirring, intelligent control and humanized operation.
