Description

Technical Field

[0001] This utility model relates to the field of greenhouse planting technology, and in particular to a greenhouse tillage device. Background Technology

[0002] When growing crops in greenhouses, the soil needs to be cultivated to loosen it. There are various types of tillage equipment. For example, patent application number 202323449896.5 discloses a soil tillage device for greenhouses. In this device, starting a motor causes a loosening rod to continuously insert and pull into the soil, loosening it, improving soil aeration, reducing the workload of the tillage plow, and extending its lifespan. Simultaneously, the plow rotates to till the soil.

[0003] Although the device can loosen the soil before the plow is turned over, in actual use, because the tillage equipment is in a continuous movement process, the vertically rising and falling loosening rod will generate mechanical impact due to inertial force and soil resistance, which will cause the loosening rod and its connecting parts to wear faster or even break. Moreover, it will periodically and greatly increase the resistance when the tillage equipment moves, resulting in increased energy consumption. Utility Model Content

[0004] This utility model proposes a greenhouse tillage device to solve the problem that existing vertical lifting soil loosening rods cause mechanical impact due to inertia and soil resistance, leading to accelerated wear or breakage of components and periodically increasing the moving resistance of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse tillage device, including a movable frame, on which tillage components are installed, and further comprising:

[0006] A watering device, connected to the tilling device, simultaneously sprays water onto the soil in the tilled area during the operation of the tilling device;

[0007] The soil loosening component is located on the front side of the tillage component along the working direction. The soil loosening section of the soil loosening component is inclined towards the tillage component, and the soil loosening component can perform periodic lifting and lowering movements.

[0008] Preferably, the tillage component includes a drive shaft and a plurality of tillage heads, the plurality of tillage heads being mounted on the outside of the drive shaft, and the drive shaft having a hollow internal structure.

[0009] Preferably, the watering component includes a water inlet pipe installed via a rotating connector and the end of a drive shaft. The drive shaft has multiple water outlet holes along its length on its exterior. The plow head has an annular water cavity inside. A water inlet channel is provided between the annular water cavity and the corresponding water outlet holes. Multiple spray holes communicating with the annular water cavity are also provided on the outer wall of the plow head.

[0010] Preferably, the water spray hole is provided with a Y-shaped diverter to allow the water sprayed from the water spray hole to be sprayed onto the surface of the tillage teeth on the tillage plow.

[0011] Preferably, the soil loosening component includes an installation strip, on which multiple inclined soil loosening strips are fixed, and a telescopic rod is installed on the upper end face of the installation strip.

[0012] Preferably, the loosening component further includes a limiting strip, which is rotatably mounted on the movable frame and has a through groove through which the loosening strip passes. The upper end of the telescopic rod is hinged to the movable frame.

[0013] Preferably, the side of the loosening strip away from the tilling component is the pointed end.

[0014] The present invention has the following advantages: (1) The loosening component drives the installation strip and the inclined loosening strip to perform periodic lifting and lowering movements through the telescopic rod, which can preliminarily treat the soil layer before the tilling component turns the soil. When the soil layer squeezes the loosening strip too much, the loosening component can deflect further toward the tilling component to reduce resistance.

[0015] (2) The water sprinkler unit is connected to the tillage unit, and water is sprinkled onto the soil layer of the tillage area at the same time during the tillage operation to achieve soil covering irrigation. Water is sprayed into the soil layer from the water spray hole of the tillage plow head. Compared with traditional surface irrigation, it can avoid a large amount of water evaporation and allow water resources to directly act on the depth area where the plant roots are located, significantly improving irrigation efficiency and reducing water loss.

[0016] (3) The Y-shaped diverter in the spray hole disperses the water flow to the surface of the tillage teeth of the tillage plow, reducing the friction coefficient between the soil and the tillage teeth, reducing equipment wear, and extending the service life of the tillage plow. At the same time, the water mist moistens the soil, making the soil loose, further reducing tillage resistance, improving tillage efficiency, and the water flow can promptly remove the mud and weeds on the surface of the tillage teeth, ensuring the continuity and stability of tillage operations.

[0028] 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.

[0029] Example 1:

[0030] like Figures 1-2 as well as Figure 4 As shown, a greenhouse tillage device includes a mobile frame 1 with wheels on both sides. A tillage component 2 is mounted on the mobile frame 1. The tillage component 2 includes a drive shaft 21 and multiple tillage heads 22. The multiple tillage heads 22 are equidistantly mounted on the outside of the drive shaft 21 along its length. A drive motor is mounted on one end of the drive shaft 21. The drive shaft 21 has a hollow internal structure. The device also includes a soil loosening component 3. The drive shaft 21 is located in front of the tillage component 2 along the working direction. The soil loosening section of the soil loosening component 3 is inclined towards the tillage component 2, and the soil loosening component 3 can perform periodic lifting and lowering movements to perform preliminary soil treatment before the tillage component 2 tills the soil.

[0031] A push-pull handle and a connecting ring can be installed at one end of the mobile frame 1 near the soil loosening component 3, so that it can be used manually with the push-pull handle for support in the greenhouse, or it can be connected to a drive device (such as a mini hand tractor) through the connecting ring, so that the drive device can drive the tillage equipment for use in the greenhouse.

[0032] In addition, the push-pull handrails can adopt an ergonomic curved design, with a non-slip rubber layer on the surface, and height-adjustable handles on both sides to accommodate operators of different heights.

[0033] See Figure 4 As shown, the loosening component 3 includes an installation strip 31, on which multiple inclined loosening strips 34 are fixed. The side of the loosening strip 34 facing away from the tillage component 2 is a pointed tip 35, which can reduce resistance when moving and contacting the soil layer, thereby reducing the occurrence of damage to the loosening strip 34. Furthermore, a telescopic rod 32 is installed on the upper end face of the installation strip 31, and the telescopic rod 32 is preferably an electric telescopic rod.

[0034] The loosening component 3 also includes a limiting strip 33, which is rotatably mounted on the movable frame 1. The limiting strip 33 has a through groove through which the loosening strip 34 passes. The upper end of the telescopic rod 32 is hinged to the movable frame 1. During the periodic extension and retraction of the telescopic rod 32, the loosening strip 34 can be periodically extended and retracted to insert into the soil and pull it out, thereby loosening the soil.

[0035] As described above, in actual use, as the tillage equipment moves within the greenhouse, the telescopic rod 32 drives the installation strip 31 to extend and retract, thereby loosening the soil by extending and retracting the loosening strip 34. Since the upper end of the telescopic rod 32 is hinged to the moving frame 1 and the limiting strip 33 can rotate, when the soil layer compresses the loosening strip 34 under excessive pressure during movement, the loosening strip 34 can further deflect towards the tillage component 2, achieving a larger angle of inclination to reduce resistance. To facilitate the reset of the telescopic rod 32 after deflection, a reset spring (not shown) can be connected between the outermost wall of the telescopic rod 32 and the moving frame 1. After the telescopic rod 32 retracts and the loosening strip 34 detaches from the soil layer, the reset spring allows the telescopic rod 32 and the loosening strip 34 to quickly return to their initial state.

[0036] In addition, to ensure the stability of the extension and retraction of the mounting strip 31, two telescopic rods 32 are symmetrically arranged. To achieve synchronous extension and retraction of the two telescopic rods 32, the following explanation is provided:

[0037] 1. Select electric telescopic poles of the same model and batch.

[0038] Core logic: Motors of the same model have consistent electrical parameters (such as torque, speed, and pulse response), and driver parameters (such as current and microstepping settings) can also be configured uniformly, reducing synchronization errors caused by hardware differences.

[0039] 2. Master-slave control mode is adopted.

[0040] Solution principle: One telescopic pole 32 is set as the master device, and the other is the slave device. The master device receives control signals and executes actions, while simultaneously synchronizing motion data (such as position and speed) to the slave device in real time. The slave device tracks the master device through closed-loop feedback.

[0041] Implementation method:

[0042] Electrical connection: The master and slave drivers are connected via a synchronous bus (such as CANopen, EtherCAT) or analog signals (such as voltage signals).

[0043] Typical scenario: The "spindle encoder + slave servo driver" mode is commonly used in servo systems. When the spindle moves, the slave axis reads the spindle position through the bus and follows it in real time.

[0044] 3. Sharing the same power supply and controller

[0045] Advantages: A unified power supply can avoid differences in motor output caused by voltage fluctuations; the same controller (such as a PLC or motion control card) can directly send synchronization commands, reducing signal transmission delay.

[0046] Precautions:

[0047] The power supply must be sufficient to support the simultaneous operation of both motors to avoid overload.

[0048] The controller must support multi-axis synchronous control functions (such as interpolation motion, electronic gearbox).

[0049] Example 2:

[0050] See Figures 1-3 as well as Figures 5-6 As shown, the greenhouse tillage equipment also includes a watering device 4, which is connected to the tillage device 2. During the operation of the tillage device 2, water is sprayed onto the soil layer of the tillage area to achieve soil covering watering, thereby replenishing water from the depth of the soil layer. This can effectively avoid the problem of large-scale water evaporation caused by traditional surface irrigation, and allow water resources to directly act on the depth area where the plant roots are located, significantly improving irrigation efficiency and reducing water loss.

[0051] See Figure 3 and Figure 5As shown, the water sprinkler 4 includes a water inlet pipe 41 installed at the end of the drive shaft 21 via a rotating connector, so that while ensuring water flow, the drive shaft 21 rotates while the water inlet pipe 41 does not rotate. Multiple water outlet holes 43 are formed along the length of the drive shaft 21. An annular water cavity 44 is provided inside the tillage head 22. A water inlet channel 45 is provided between the annular water cavity 44 and the corresponding water outlet hole 43. Multiple spray holes 42 communicating with the annular water cavity 44 are also formed on the outer wall of the tillage head 22. The aforementioned rotating connector can be a rotary joint. Structure: It consists of inner and outer rotating parts that cooperate with each other. The inner part is usually connected to the water inlet pipe 41, and the outer part is connected to the end of the drive shaft 21. A sealing device, such as a sealing ring, is provided between the inner and outer parts to prevent water leakage, while allowing them to rotate relative to each other. This structure allows the water inlet pipe 41 to rotate flexibly under the drive shaft 21, while ensuring normal water delivery and sealing. For example, this type of rotary joint is often used to connect the water inlet pipe 41 of some industrial sprinkler equipment to the drive shaft 21, which can adapt to different working angles and rotation requirements.

[0052] As described above, during use, the water inlet pipe 41 is connected to a water delivery hose. While turning the soil, water is delivered into the water inlet pipe 41 through the water delivery hose. The water can enter the corresponding water inlet channel 45 through the water outlet 43 on the drive shaft 21, and then enter the annular water chamber 44 inside the tillage plow head 22. Finally, it is sprayed out from the water spray hole 42 into the soil layer.

[0053] See Figure 5 and Figure 6 As shown, a Y-shaped diverter 46 is provided inside the water spray hole 42 to spray water from the water spray hole 42 onto the surface of the tillage teeth on the tillage head 22. When water flows into the water spray hole 42 from the annular water cavity 44, the Y-shaped diverter 46 disperses the concentrated water flow into two streams, which are then sprayed onto the surface of the tillage teeth on the tillage head 22. Firstly, this effectively reduces the coefficient of friction between the soil and the tillage teeth during tillage, reduces equipment wear, extends the service life of the tillage head 22, and reduces maintenance costs. Secondly, the water mist can quickly moisten the soil around the tillage teeth, making the dry and compacted soil loose, reducing tillage resistance, and improving tillage efficiency. Thirdly, the continuous scouring of the tillage teeth by the water flow can promptly remove the mud and weeds attached to the surface of the tillage teeth, preventing the accumulation of residues from affecting the tillage effect and ensuring the continuity and stability of the tillage operation.

[0054] In addition, to prevent soil from clogging the water spray holes 42 during tilling, the water spray holes 42 can be designed to be inclined so that the direction of water jetting forms a certain angle (such as 30°-45°) with the rotation direction of the tilling teeth. During tilling, the inclined water jetting will generate an outward thrust on the surface of the tilling teeth, pushing away the soil particles close to the water spray holes 42 in time, thus preventing soil accumulation and clogging.

[0055] Alternatively, the inner wall of the water jet 42 can be designed as a spiral guide channel, forming a rotating jet when water flows through it. This swirling water column not only enhances the scouring effect on the tillage teeth, but also creates a centrifugal force field around the water jet 42, causing nearby soil particles to be thrown out and preventing blockage. The spiral angle can be optimized according to water pressure and flow rate.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
