Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly to a soil loosener. Background Art

[0002] A soil loosener generally consists of a frame, a plowshare, a plow blade, a suspension device and a power part. The frame is the main structure of the whole machine. The plowshare and the plow blade are the key components for tilling the soil. The suspension device is used to connect the tractor and the soil loosener, and the power part provides power for the whole machine. Under the traction of the tractor, the soil loosener relies on the plowshare and the plow blade to till and loosen the soil. The plow blade cuts the soil into strips, and the plowshare turns up the soil strips to separate them from the soil structure. By repeating this process multiple times, the purpose of tilling and loosening the soil is achieved.

[0003] Chinese Patent Application for Invention (Publication No. CN104737645A) discloses a multi-functional soil loosener, which includes a frame, a soil loosening knife assembly, a push rod and a walking wheel. A machine shell is arranged on the frame. An electric motor and a clutch are respectively installed in the machine shell. A reduction mechanism is further arranged at the bottom of the frame. The soil loosener further includes a first auxiliary wheel and a grooving knife assembly, a trimming knife and a lawn combing knife assembly that can replace the soil loosening knife assembly to work respectively. The soil loosening knife assembly includes a first sleeve and a soil loosening blade group fixedly sleeved outside the first sleeve. The grooving knife assembly includes a second sleeve and a grooving blade group fixedly sleeved outside the second sleeve. The trimming knife includes a third sleeve and a cutter head fixedly arranged on the third sleeve. The lawn combing knife assembly includes a lawn combing wheel. A plurality of mounting grooves are arranged on the lawn combing wheel. A convex column is arranged in the mounting groove, and a lawn combing torsion spring is sleeved on the convex column.

Especially in the case of relatively dry soil, the soil loosening knife assembly is prone to turn up the soil during rotation. At this time, if there is wind, the turned-up soil will carry a large amount of dust and float in the air, forming a dust-raising phenomenon. This will not only deteriorate the working environment, increase the labor intensity and discomfort of the operator, but more importantly, long-term exposure to the dust-raising environment will cause damage to the respiratory system of the operator and increase the risk of suffering from respiratory diseases. Summary of the Invention

[0005] In view of the above problems, a soil loosener is provided, which can effectively protect the working environment and improve the safety of operation through a soil loosening and dust reduction device.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. By integrating a soil loosening and dust reduction device, the rototiller realizes the instant dust reduction function during the soil loosening operation.

[0018] 2. The spraying diversion baffle in the soil loosening and dust reduction device serves as a physical barrier, effectively blocking the soil particles turned up during the soil loosening process from directly hitting the dust reduction nozzle, avoiding the risk of nozzle blockage, and thus ensuring the continuous and efficient operation of the dust reduction system. In addition, the design of the spraying diversion baffle also optimizes the distribution of the dust reduction droplets, improving the dust reduction efficiency. This innovative design not only enhances the system stability of the rototiller, reduces the downtime and maintenance costs caused by nozzle blockage, ensures the efficient progress of the soil loosening operation, but also improves the overall operation efficiency and equipment performance.

[0032] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the drawings and specific implementation manners.

[0033] Referring to Figures 1 to 11 as shown, a scarifier includes a soil loosening and dust suppression device installed on the scarifier 1. The soil loosening and dust suppression device includes a plurality of spraying diversion baffles 2 detachably installed above the soil loosening blades. A dust suppression nozzle 3 is installed inside each spraying diversion baffle 2. The spraying diversion baffle 2 is used to prevent soil from directly contacting the dust suppression nozzle 3. When the soil loosening blade turns the soil, the dust suppression nozzle 3 cooperates with the spraying diversion baffle 2 to atomize and spray dust suppression. The soil loosening and dust suppression device also includes a water delivery device 4 installed on the scarifier 1. The water delivery device 4 delivers dust suppression liquid to each dust suppression nozzle 3.

[0034] The soil loosening and dust reduction device includes a plurality of spraying and guiding baffles 2 detachably installed above the soil loosening blade assembly. Each spraying and guiding baffle 2 is internally embedded with a dust reduction nozzle 3, and its design purpose is to use the spraying and guiding baffle 2 as a physical barrier to prevent the soil turned up during the soil loosening process from directly hitting and potentially clogging the dust reduction nozzle 3.

[0035] During the operation, when the operator drives the power tiller 1 to the designated soil loosening area, the soil loosening blade assembly starts to rotate and contacts the ground soil to perform the soil loosening operation. Especially under dry soil conditions, the soil loosening operation is prone to cause dust to fly. To address this situation, the operator can activate the water supply device 4, which is responsible for supplying the dust reduction liquid to each dust reduction nozzle 3.

[0036] Once the water supply device 4 is started, the dust reduction liquid is pumped to the dust reduction nozzle 3, and the nozzle immediately sprays the dust reduction liquid in an atomized form. These fine dust reduction droplets pass through the spraying and guiding baffle 2, contact and combine with the dust particles suspended in the air, effectively suppressing the spread of dust. The presence of the spraying and guiding baffle 2 not only ensures the effective distribution of the dust reduction mist, but also serves as a barrier to prevent soil particles from directly contacting and potentially clogging the dust reduction nozzle 3, thus maintaining the continuous and efficient operation of the dust reduction system.

[0037] Through the integrated soil loosening and dust reduction device, the power tiller 1 achieves an immediate dust reduction effect during the soil loosening operation, effectively improving the operation environment, reducing the risk of the operator being exposed to harmful dust, and at the same time ensuring the long-term stable operation of the equipment, reflecting the combination of environmental protection and efficient operation concepts.

[0038] See Figures 1 to 6 As shown, the spraying and guiding baffle 2 includes a sleeve fixed shell 21. The sleeve fixed shell 21 is provided with a sleeve slot 211. The bottom of the sleeve fixed shell 21 is provided with a number of equally spaced inclined mudguard strips 23, and the gaps between the inclined mudguard strips 23 form a spraying channel.

[0039] The spraying and guiding baffle 2 is composed of a sleeve fixed shell 21, which is designed with a sleeve slot 211 to facilitate the detachable installation of the spraying and guiding baffle 2 above the soil loosening blade assembly of the power tiller 1. The bottom of the sleeve fixed shell 21 is provided with a number of equally spaced inclined mudguard strips 23, and the gaps formed between the inclined mudguard strips 23 constitute the spraying channel. An installation gap is reserved between the inclined mudguard strips 23 and the sleeve fixed shell 21 for installing the dust reduction nozzle 3.

[0040] During operation, the rotation of the scarifier blades may generate flying soil particles. The inclined mudguards 23 are designed at an angle to effectively block these flying soil particles, preventing them from directly impacting and potentially clogging the dust suppression nozzles 3 located within the installation gap. Furthermore, the spraying channels between the inclined mudguards 23 allow the dust suppression liquid to pass through in atomized form, ensuring that the dust suppression droplets are evenly distributed and interact with dust particles suspended in the air, achieving the desired dust reduction effect.

[0041] See also Figures 1 to 3 As shown, a limit locking mechanism 22 is installed above the set fixing shell 21. The limit locking mechanism 22 includes a limit sliding sleeve 221 installed on the top of the set fixing shell 21. The interior of the limit sliding sleeve 221 is provided with a movable resistance block 222 that moves toward the set card slot 211.

[0042] The contact surface of the movable contact block 222 is provided with anti-slip teeth, and an adjusting screw 225 is also installed on the limiting sliding sleeve 221.

[0043] The limiting sleeve 221 is securely mounted on top of the sleeve fixed housing 21. The internal space of the limiting sleeve 221 accommodates and guides the movement of the movable interference block 222. The movable interference block 222, a key locking component, is capable of moving in a specific direction within the limiting sleeve 221. The anti-slip teeth of the movable interference block 222 enhance friction with the contact surface of the sleeve slot 211, ensuring that the movable interference block 222 can securely maintain its position when subjected to external forces, thereby stably securing the sleeve fixed housing 21. The adjusting screw 225 is threadedly connected to the limiting sleeve 221, allowing the adjusting screw 225 to rotate and move along its axial direction. The extended end of the adjusting screw 225 is rotationally connected to the movable interference block 222. Thus, when a worker rotates the adjusting screw 225, the transmission effect of the threads propels the movable interference block 222 along the internal space of the limiting sleeve 221 toward the sleeve slot 211.

[0044] During the actual installation of the ripper 1, the mounting slot 211 of the mounting fixing housing 21 is first accurately mounted on the corresponding mounting portion of the ripper 1. Subsequently, the operator gradually increases the contact between the movable contact block 222 and the mounting portion of the ripper 1 by rotating the adjustment screw 225 until a stable fixation is achieved. During this process, the anti-slip teeth effectively prevent the movable contact block 222 from sliding when subjected to external forces, thereby ensuring the secure and stable installation of the spray guide baffle 2.

[0045] See also Figure 3 and Figure 4As shown, the spraying diversion baffle 2 further includes a cleaning mechanism 24 for the cleaning dust reduction nozzles 3 and the inclined mud guards 23. The cleaning mechanism 24 includes a sliding scraper 241 slidably installed between the cleaning dust reduction nozzles 3 and the inclined mud guards 23. The sliding scraper 241 is used to clean the cleaning dust reduction nozzles 3 and the inclined mud guards 23. The cleaning mechanism 24 further includes a pulling adjustment mechanism 242 for adjusting the movement of the sliding scraper 241.

[0046] During the soil loosening operation, although the inclined mud guards 23 can effectively prevent the direct contact between soil particles and the dust reduction nozzles 3, the atomized liquid sprayed by the dust reduction nozzles 3 will keep the inclined mud guards 23 in a wet state. Being in a wet environment for a long time, the inclined mud guards 23 may adhere due to contact with the soil, which may then lead to blockage, reducing the atomization effect and affecting the dust reduction performance.

[0047] When the operator observes an increase in the dust concentration, indicating a possible risk of blockage of the inclined mud guards 23 or the dust reduction nozzles 3, the position of the sliding scraper 241 can be adjusted by operating the pulling adjustment mechanism 242. During the movement of the sliding scraper 241, it can scrape off the soil and impurities attached to the cleaning dust reduction nozzles 3 and the inclined mud guards 23, thus effectively preventing the occurrence of blockage and ensuring the continuous and efficient operation of the dust reduction system. This design not only improves the maintenance convenience of the soil loosener 1 but also further enhances its environmental protection and efficient operation capabilities.

[0048] See Figures 4 to 7 As shown, a plurality of mud scraping grooves 2411 are provided at the bottom of the sliding scraper 241. The mud scraping grooves 2411 correspond to the inclined mud guards 23 one by one. A cleaning scraping strip 2412 is provided at the top of the sliding scraper 241. The cleaning scraping strip 2412 contacts the spraying end of the dust reduction nozzle 3.

[0049] During the cleaning process, the operator drives the sliding scraper 241 to slide along a preset path through the pulling adjustment mechanism 242. The mud scraping grooves 2411 slide along the surface of the inclined mud guards 23 as the sliding scraper 241 moves, effectively scraping off the soil and impurities adhered due to long-term wetness and preventing the occurrence of blockage. At the same time, the cleaning scraping strip 2412 contacts the spraying end of the dust reduction nozzle 3 to ensure the cleanliness of the surface of the dust reduction nozzle 3 and prevent the influence of impurity accumulation on its atomization effect.

[0050] So that when the sliding scraper 241 cleans the cleaning dust reduction nozzles 3 and the inclined mud guards 23, it can comprehensively and efficiently scrape off the attachments, thus ensuring the continuous and efficient operation of the dust reduction system. The working principle of the sliding scraper 241 reflects the improvement of the maintenance convenience of the soil loosener 1.

[0051] See Figures 3 to 11As shown, the pulling and adjusting mechanism 242 includes a return spring 2421 installed between the sliding scraper 241 and the sleeve fixed housing 21. The pulling and adjusting mechanism 242 includes a sliding pull rod 2422 connected to the sliding scraper 241. A pulling rope 2423 is installed on the sliding pull rod 2422. The pulling and adjusting mechanism 242 further includes a guide frame 2424 for guiding the movement of the pulling rope 2423.

[0052] The return spring 2421 is installed between the sliding scraper 241 and the sleeve fixed housing 21 to provide a return force for the sliding scraper 241. The sliding pull rod 2422 is connected to the sliding scraper 241 and is responsible for directly driving the movement of the sliding scraper 241. The pulling rope 2423 is connected to the sliding pull rod 2422, and the remote driving of the sliding pull rod 2422 is realized through external operation. The guide frame 2424 is used to guide the movement path of the pulling rope 2423 to ensure the smoothness and accuracy of the pulling action. The synchronous connection pull rod 2425 is connected to multiple pulling ropes 2423 to realize the movement of multiple sliding scrapers 241 being driven simultaneously with one operation.

[0053] When the position of the sliding scraper 241 needs to be adjusted, the operator first pulls the synchronous connection pull rod 2425. The movement of the synchronous connection pull rod 2425 will drive the multiple pulling ropes 2423 connected to it to move synchronously. The pulling force of the pulling rope 2423 is transmitted to the sliding scraper 241 through the sliding pull rod 2422, driving it to move along the preset path. During the movement of the sliding scraper 241, the return spring 2421 is gradually compressed and stores elastic potential energy.

[0054] When the sliding scraper 241 moves to the required position, the operator stops pulling the synchronous connection pull rod 2425. At this time, the return spring 2421 releases the stored elastic potential energy, pushing the sliding scraper 241 to move in the opposite direction until it returns to the initial position or the predetermined position. This process ensures that the sliding scraper 241 can automatically reset after the cleaning operation, facilitating the next cleaning operation.

[0055] The working principle of the pulling and adjusting mechanism 242 reflects the precise control and convenient adjustment of the position of the sliding scraper 241. The movement and reset of the sliding scraper 241 can be realized through a simple pulling action, greatly improving the maintenance convenience of the tiller 1 and the operation efficiency of the dust reduction system.

[0056] See Figures 1 to 3 As shown, a number of spray holes are distributed on the dust reduction nozzle 3, and the spray holes correspond to the spraying channels one by one.

[0057] During the soil loosening operation, when the water delivery device 4 is activated, the dust suppression liquid is conveyed to the dust suppression nozzles 3. After the pressure regulation and flow distribution inside the nozzles, the dust suppression liquid is sprayed out in the form of atomization through each spray hole. Since the spray holes correspond to the spraying channels one by one, the dust suppression droplets can precisely pass through the spraying channels, achieving the uniform distribution and diffusion of the dust suppression liquid.

[0058] See Figures 1 to 8 As shown, the water delivery device 4 includes an assembled bracket 41 installed on the soil loosener 1. A delivery pump 42 is installed on the assembled bracket 41, and a water storage tank 43 is also installed on the assembled bracket 41. The water storage tank 43 is communicated with the delivery pump 42, and the water storage tank 43 is detachably connected to the assembled bracket 41.

[0059] In the work process, the water storage tank 43 stores sufficient dust suppression liquid. When the soil loosening operation is started and dust suppression is required, the delivery pump 42 is activated. The delivery pump 42 pumps out the dust suppression liquid in the water storage tank 43 and pressurizes it for delivery to its output end. The output end is connected to each dust suppression nozzle 3 to ensure that the dust suppression liquid can be supplied to the nozzles with a certain pressure and flow rate. The nozzles then atomize the dust suppression liquid to form fine droplets, and these droplets are evenly dispersed to the operation area through the spraying guide baffle 2, combining with the dust particles in the air to achieve the dust suppression effect. The detachable design of the assembled bracket 41 not only facilitates the installation and maintenance of the water storage tank 43 but also ensures the flexible configuration and efficient operation of the entire water delivery device 4 on the soil loosener 1.

[0060] See Figures 8 to 11 As shown, the assembled bracket 41 is provided with a connection joint 412 and a positioning column 411. Both the connection joint 412 and the positioning column 411 are docked with the bottom of the water storage tank 43. The connection joint 412 is communicated with the water storage tank 43, and a support frame 413 is also installed on the assembled bracket 41. The support frame 413 is used to support the water storage tank 43.

[0061] The support frame 413 can provide an installation path for the synchronous connection pull rod 2425. The synchronous connection pull rod 2425 is slidably connected to the support frame 413 to facilitate the stable pulling of the synchronous connection pull rod 2425. The connection joint 412 is simultaneously connected to the input end of the delivery pump 42.

[0062] The main function of the assembled bracket 41 is to stably support and rationally arrange the water storage tank 43 and the delivery pump 42. The connection joint 412 on the bracket is responsible for establishing the fluid channel between the water storage tank 43 and the delivery pump 42, ensuring that the dust suppression liquid can be smoothly pumped out from the water storage tank 43 and conveyed to the delivery pump 42. The positioning column 411 plays the role of precisely docking the bottom of the water storage tank 43, not only ensuring the stable installation of the water storage tank 43 on the assembled bracket 41 but also ensuring the accurate docking of the connection joint 412 with the water outlet of the water storage tank 43, avoiding the risk of liquid leakage.

[0063] In addition, the support frame 413 equipped on the assembly bracket 41 mainly provides additional support force for the water storage tank 43, enhancing the structural stability of the entire water delivery device 4. This enables the water storage tank 43 to be conveniently adjusted in position during installation, disassembly, and maintenance, further improving the operational convenience and efficiency.

[0064] See Figures 8 to 11 As shown, the bottom of the water storage tank 43 is provided with positioning alignment holes 431 and connection interfaces 432. The positioning alignment holes 431 are docked with the positioning columns 411, and the connection interfaces 432 are connected to the connection joints 412. An active plug shaft 433 is also provided inside the water storage tank 43. A push spring 434 is installed between the active plug shaft 433 and the water storage tank 43, and the active plug shaft 433 is coaxially arranged with the connection interface 432.

[0065] The water storage tank 43 is used to store the dust suppression liquid and ensure its smooth supply to the transfer pump 42 when needed. The bottom of the water storage tank 43 is designed with positioning alignment holes 431 and connection interfaces 432. The positioning alignment holes 431 are accurately docked with the positioning columns 411 on the assembly bracket 41, not only ensuring the stable installation of the water storage tank 43 on the assembly bracket 41 but also avoiding the risk of liquid leakage caused by improper installation. At the same time, the connection interfaces 432 are closely connected to the connection joints 412 on the assembly bracket 41, forming a fluid channel for the dust suppression liquid to flow from the water storage tank 43 to the transfer pump 42. An active plug shaft 433 is also provided inside the water storage tank 43. A push spring 434 is installed between the active plug shaft 433 and the water storage tank 43, and the active plug shaft 433 is coaxially arranged with the connection interface 432. It is ensured that when the connection joint 412 is inserted into the connection interface 432, the active plug shaft 433 will be pushed up, thereby opening the connection interface 432, enabling the dust suppression liquid inside the water storage tank 43 to flow smoothly to the transfer pump 42. When the water storage tank 43 needs to be disassembled or maintained, the active plug shaft 433 will automatically reset under the action of the push spring 434 to close the connection interface 432, effectively preventing liquid leakage.

[0066] Specific working principle:

[0067] During the operation process, when the operator drives the ripper 1 to the designated soil loosening area, the soil loosening knife assembly starts to rotate and contacts the ground soil to perform the soil loosening operation. Especially under dry soil conditions, the soil loosening operation is likely to cause dust to fly. To address this situation, the operator can activate the water delivery device 4, which is responsible for supplying the dust suppression liquid to each dust suppression nozzle 3.

[0068] Once the water delivery device 4 is activated, the dust suppression liquid is pumped to the dust suppression nozzle 3, and the nozzle immediately sprays the dust suppression liquid in an atomized form. These fine dust suppression droplets pass through the spraying diversion baffle 2, contact and combine with the dust particles suspended in the air, effectively suppressing the spread of dust. The presence of the spraying diversion baffle 2 not only ensures the effective distribution of the dust suppression fog, but also serves as a barrier to prevent soil particles from directly contacting and potentially clogging the dust suppression nozzle 3, thus maintaining the continuous and efficient operation of the dust suppression system.

[0069] The ripper 1 achieves an immediate dust suppression effect during the ripping operation through the integrated ripping and dust suppression device, effectively improving the working environment, reducing the risk of operators being exposed to harmful dust, and at the same time ensuring the long-term stable operation of the equipment, reflecting the combination of environmental protection and efficient operation concepts.

[0070] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
