Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a water-retaining agent application device. Background Technology

[0002] Water-retaining agents have a wide range of applications, including afforestation, fruit tree horticulture, crop cultivation, lawn establishment and maintenance, landscaping, slope protection, desert vegetation planting, fertilizer substrate mixing, and hydroponics. They play a crucial role in the arid and rain-scarce Northwest region. Water-retaining agents can be applied in various ways, such as trenching and hole application. They have a strong ability to absorb and retain water, but they also decompose easily on the soil surface. Therefore, they are generally covered with soil or mixed with soil to ensure even distribution. Manual application is inefficient and labor-intensive.

[0003] In response, application number 202322338469.3, entitled "A device for applying and covering soil with water-retaining agent for agricultural and forestry use," describes a device that connects a connecting rod to a tractor or other tractor via a connecting hole. In use, the water-retaining agent is poured into a spreading box, and the device is moved by the tractor. During movement, a V-shaped plow inserts into the soil, and then a V-shaped soil-separating plate separates the soil to both sides into the covering hole. Next, the motor is started to allow the water-retaining agent to fall, and the V-shaped covering plate pushes the separated soil back to its original position, covering the fallen water-retaining agent. This device can automatically apply the water-retaining agent and cover it with soil.

[0004] This device improves the efficiency of water-retaining agent application. However, this method is suitable for situations where the trench bottom is relatively flat. If the trench is narrow and deep, for example, when applying water-retaining agent to a vineyard, a trench 30-50 cm deep needs to be dug along the direction of the grape trellis. In this case, the water-retaining agent is prone to rolling to the bottom of the trench, causing local accumulation and leading to root rot. In severe cases, it can cause root rot and plant death. Utility Model Content

[0005] In view of this, this application proposes a water-retaining agent application device that mixes the water-retaining agent with the soil after trenching, thereby reducing the occurrence of localized aggregation of the water-retaining agent.

[0006] A water-retaining agent application device includes a frame;

[0007] The trenching mechanism, soil mixing mechanism, soil spreading mechanism, soil gathering mechanism, and support wheel assembly are connected to the frame.

[0008] The trenching mechanism is located at the front of the frame, the soil mixing mechanism is located behind the trenching mechanism, the spreading mechanism is located above the soil mixing mechanism, and the soil gathering mechanism is located behind the soil mixing mechanism.

[0009] Preferably, the trenching mechanism is located on both sides of the frame. The trenching mechanism includes a clamp, a vertical connecting rod, and a plow. One end of the clamp is detachably connected to the frame, and the other end of the clamp is sleeved and connected to the upper end of the vertical connecting rod. The lower end of the vertical connecting rod is fixedly connected to the plow.

[0010] Preferably, the vertical connecting rod is height-adjustable.

[0011] Preferably, the soil mixing mechanism includes a mixing shaft, a suspension, and mixing blades. One end of the mixing shaft is connected to the frame, the other end of the mixing shaft is connected to the lower end of the suspension, the upper end of the suspension is connected to the frame, and the mixing blades are mounted on the mixing shaft.

[0012] Furthermore, the stirring blades are spiral-shaped.

[0013] Preferably, the spreading mechanism includes a material box, a distributing shaft, and a guide pipe. The material box is located above the frame, and the bottom of the material box is provided with several distributing grooves. The bottom of the distributing grooves is provided with a discharge port. The distributing shaft passes through the distributing grooves and is provided with several discharge holes. The diameter of the distributing shaft corresponds to the discharge port. The inlet of the guide pipe is located below the distributing port and is connected to the distributing port. The outlet of the guide pipe is located above the soil mixing mechanism.

[0014] Preferably, the soil-gathering mechanism includes a soil-gathering frame and two soil-gathering plates. One end of the soil-gathering frame is fixedly connected to the machine frame, and the other end of the soil-gathering frame is fixedly connected to the soil-gathering plates. The soil-gathering plates are V-shaped.

[0015] Preferably, the support wheel assembly includes a longitudinal connecting rod, a vertical support rod, and a support wheel. One end of the longitudinal connecting rod is fixedly connected to the frame, the other end of the longitudinal connecting rod is connected to the vertical support rod, and the lower end of the vertical support rod is connected to the support wheel.

[0016] Preferably, the frame is equipped with a transfer case, the power input end of which is connected to the drive shaft of an external tractor, and the power output end of which is connected to the mixing shaft.

[0017] Furthermore, the power output end of the transfer case is connected to the stirring shaft via a universal coupling.

[0018] Compared with existing technologies, the beneficial effect of this application is that after the trenching mechanism opens the trench, the soil mixing mechanism mixes the soil and water-retaining agent, and then the soil covering mechanism covers the soil. In this way, the soil and water-retaining agent are mixed while the trench is being opened, making it difficult for the water-retaining agent to accumulate at the bottom of the trench, thereby significantly reducing the occurrence of root rot.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0028] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] Please refer to Figures 1 to 6 The water-retaining agent application device of this application includes a frame 10;

[0030] The trenching mechanism 20, soil mixing mechanism 30, spreading mechanism 40, soil gathering mechanism 50, and support wheel assembly 60 are connected to the frame 10.

[0031] The trenching mechanism 20 is located at the front end of the frame 10, the soil mixing mechanism 30 is located behind the trenching mechanism 20, the spreading mechanism 40 is located above the soil mixing mechanism 30, and the soil gathering mechanism 50 is located behind the soil mixing mechanism 30.

[0032] The frame 10 of this application is used to connect to a tractor, and also to connect to the trenching mechanism 20, the soil mixing mechanism 30, the spreading mechanism 40, the soil raking mechanism 50, and the support wheel assembly 60. The frame 10 can be welded to the trenching mechanism 20 or can be detached and connected.

[0033] In a preferred embodiment, the trenching mechanism 20 is located on both sides of the frame 10. The trenching mechanism 20 includes a clamp 201, a vertical connecting rod 202, and a plow head 203. One end of the clamp 201 is detachably connected to the frame 10, the other end of the clamp 201 is sleeved and connected to the upper end of the vertical connecting rod 202, and the lower end of the vertical connecting rod 202 is fixedly connected to the plow head 203.

[0034] The ditching mechanisms 20 installed on both sides of the frame 10 are suitable for applying water-retaining agents in orchards, such as vineyards and goji berry gardens. Currently, mature orchards are planted in rows, facilitating both mechanized access and manual management. In this application, after entering the orchard, the ditching mechanisms 20 on both sides dig ditches next to the fruit trees on both sides. This allows the water-retaining agent to act near the root system, enhancing water retention.

[0035] In a further preferred embodiment, the clamp 201 has an upper clamping plate and a lower clamping plate, with opposite through holes on the upper and lower clamping plates. Bolts pass through the upper and lower clamping plates and are fixed by nuts. At the bottom of the lower clamping plate, a connecting plate is provided. The connecting plate and the lower clamping plate can be integrally formed by casting or welded together from two plates. A sleeve is provided at the horizontal end of the connecting plate, allowing the clamp 201 to be sleeved and connected to the vertical connecting rod 202. The purpose of this sleeved connection is to adjust the position of the vertical connecting rod 202, thereby adjusting the trenching depth. Existing technology commonly uses plowshares 203 to adjust trenching depth. For example, the sleeve and the vertical connecting rod 202 each have a row of adjustment holes in the vertical direction. The position between the sleeve and the vertical connecting rod 202 is adjusted by a pin, thereby adjusting the trenching depth. Therefore, this application will not elaborate further.

[0036] The soil mixing mechanism 30 of this application is located behind the trenching mechanism 20. After the trenching mechanism 20 finishes trenching, it mixes the soil on both sides of the trench while the soil is still loose, which can loosen and distribute the soil. During this process, the spreading mechanism 40 above the soil mixing mechanism 30 spreads out the water-retaining agent, which is then mixed with the soil.

[0037] In a preferred embodiment, the soil mixing mechanism 30 includes a mixing shaft 301, a suspension 302, and mixing blades 303. One end of the mixing shaft 301 is connected to the frame 10, the other end of the mixing shaft 301 is connected to the lower end of the suspension 302, the upper end of the suspension 302 is connected to the frame 10, and the mixing blades 303 are disposed on the mixing shaft 301.

[0038] The frame 10 of this application is equipped with a drive mechanism, which drives the mixing shaft 301 to rotate. The drive mechanism can be an independent drive motor, or it can cooperate with the drive shaft of a tractor to drive the mixing shaft 301 to rotate. While the mixing shaft 301 rotates, it drives the mixing blades 303 to rotate, thereby agitating the nearby soil. During the agitation process, the water-retaining agent is incorporated into the soil.

[0039] There are many types of stirring blades 303, such as paddle blades and claw blades.

[0040] To fully agitate the soil without throwing it too high, in a preferred embodiment, the agitator blades 303 are spiral-shaped. The spiral blades effectively agitate the soil, while the blade-like structure penetrates deep into the soil with minimal damage. The spiral blades can be continuous or discontinuous. When the spiral blades are continuous, they propel the soil forward, preventing siltation as the tractor also moves forward synchronously.

[0041] The spreading mechanism 40 of this application is located above the soil mixing mechanism 30. The spreading mechanism 40 is used to spread the water-retaining agent. It should be noted that the amount of water-retaining agent used in the field is small, generally only a few kilograms. Therefore, it is necessary to strictly control the amount of water-retaining agent used.

[0042] In a preferred embodiment, the spreading mechanism 40 includes a material box 401, a material distribution shaft 402, and a guide pipe 403. The material box 401 is located above the frame 10. The bottom of the material box 401 is provided with a plurality of material distribution grooves 4011. The bottom of the material distribution grooves 4011 is provided with a discharge port. The material distribution shaft 402 passes through the material distribution grooves 4011 and is provided with a plurality of discharge holes. The diameter of the material distribution shaft 402 corresponds to the discharge port. The inlet of the guide pipe 403 is located below the material distribution port and is connected to the material distribution port. The outlet of the guide pipe 403 is located above the soil mixing mechanism 30.

[0043] The diameter of the dispensing shaft 402 described in this application corresponds to the discharge port. Specifically, the dispensing shaft can block the discharge port to prevent the water-retaining agent in the material box from flowing out through the gap between the dispensing shaft and the discharge port. The dispensing shaft is provided with a discharge hole. As the dispensing shaft rotates, the water-retaining agent that enters the discharge hole, after passing the upper part of the dispensing shaft, leaves the dispensing shaft due to the action of tumbling and gravity, and finally enters the guide tube 403.

[0044] In a preferred embodiment, the feeding directions of two adjacent guide tubes 403 are opposite. For example, if the feeding direction of the first guide tube 403 is to the left, then the feeding direction of the second guide tube 403 is to the right. In this way, the guide tubes 403 are arranged alternately.

[0045] The water-retaining agent at the bottom of the material box 401 is on the distribution shaft 402. As the distribution shaft 402 rotates, the water-retaining agent in the discharge hole is discharged into the guide pipe 403 and reaches the soil mixing mechanism 30 above it, where it is then mixed into the soil. The amount of water-retaining agent added can be controlled by adjusting the rotational speed of the distribution shaft 402 and the tractor's travel speed.

[0046] The material distribution shaft 402 can be driven by the tractor's drive shaft or by an independently installed motor. When the material distribution shaft 402 is driven by the tractor's drive shaft, it is connected to the drive shaft via chain or belt drive.

[0047] The soil-leveling mechanism 50 of this application is used to level the opened trench so that the water-retaining agent is located below the soil.

[0048] In a preferred embodiment, the soil-gathering mechanism 50 includes a soil-gathering frame 501 and two soil-gathering plates 502. One end of the soil-gathering frame 501 is fixedly connected to the frame 10, and the other end of the soil-gathering frame 501 is fixedly connected to the soil-gathering plates 502. The soil-gathering plates 502 are V-shaped.

[0049] During its movement, the two jacks 502 will bring the soil that has risen on both sides into the ditch.

[0050] The support wheel assembly 60 of this application is used to support the rear end of the frame 10. The contact area between the rear end plate 502 of the frame 10 and the ground is very small, and the frame 10 itself is relatively heavy. Without support, the plate 502 would sink into the soil. During movement, more and more soil would accumulate in front of the plate 502, increasing resistance. With the support wheel assembly 60, the pressure on the plate 502 is reduced, preventing it from sinking into the soil.

[0051] In a preferred embodiment, the support wheel assembly 60 includes a longitudinal connecting rod 601, a vertical support rod 602, and a support wheel 603. One end of the longitudinal connecting rod 601 is fixedly connected to the frame 10, the other end of the longitudinal connecting rod 601 is connected to the vertical support rod 602, and the lower end of the vertical support rod 602 is connected to the support wheel 603.

[0052] The longitudinal connecting rod 601 can be sleeved and connected to the vertical support rod 602, and the height of the support wheel 603 can be adjusted by setting an adjustment hole and pin connection.

[0053] When the tractor's drive shaft drives the mixing shaft 301 and the distributing shaft 402 to rotate, in a preferred embodiment, the frame 10 is provided with a transfer case 101. The power input end of the transfer case 101 is connected to the drive shaft of the external tractor, and the power output end of the transfer case 101 is connected to the mixing shaft 301.

[0054] The power output end of the transfer case 101 and the stirring shaft 301 can be connected by a chain drive or by a coupling. Considering the working environment of the stirring shaft 301, in a preferred embodiment, the power output end of the transfer case 101 and the stirring shaft 301 are connected by a universal coupling 1011.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
