Technical Field

[0001] The invention relates to the technical field of soil loosening equipment, in particular to a soil loosening device for agricultural planting. Background Art

[0002] Soil loosening is an important soil management technology. It can loosen the soil, dredge the air, increase the ground temperature, and is also beneficial to the activity of soil microorganisms, promote the decomposition of organic matter, increase the soil nutrient supply capacity, and improve nutritional conditions. When loosening the soil, the traditional way is to use farm tools to loosen the soil, but with the continuous development of technology, mechanized soil loosening devices have been widely used.

[0003] For example, the patent with announcement number CN219269489U: A soil loosening device for agricultural planting, including a frame, the frame having a mounting bracket, a drive shaft rotatably mounted inside the frame, and a plurality of soil turning components equidistantly distributed on the outer wall of the drive shaft. In this patent, the spacing between each group of rotary tillage blades can be reduced by setting a plurality of cutting blades on both sides of the ends of the rotary tillage blades, and the cutting blades can be driven to move synchronously when the rotary tillage blades move, so as to cut the soil blocks, further reduce the volume of the soil blocks, and make the soil after the loosening work more delicate and loose, which is convenient for sowing production work.

This patent connects the stirring teeth to the fixed plate through a connecting circular plate, and when the connecting rod rotates, the stirring teeth on the circular plate are driven to stir the soil, avoiding the situation where hard soil is difficult to loosen, and by setting a protective structure on the loosening body, the protectiveness of the loosening equipment during use is improved.

[0005] However, the current loosening devices for agricultural planting still have some shortcomings during use, such as: when loosening the soil, stones in the soil collide with the loosening knife, causing it to deform or even break, affecting the loosening effect; the current loosening device cannot handle stones in the soil, and in agricultural planting, loosening the soil often needs to be carried out at regular intervals, which causes the loosening knife to still collide during subsequent loosening; when the soil is relatively dry, although the loosening knife can turn over the soil, the loosening depth often does not meet the planting requirements, resulting in the need for repeated loosening, which is inconvenient.

DETAILED DESCRIPTION

[0021] 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.

[0022] In order to solve the technical problem that when loosening the soil, the stones in the soil collide with the loosening knife, causing it to deform or even break, affecting the loosening effect, such as Figure 1 - Figure 5 As shown, the following preferred technical solutions are provided: A soil loosening device for agricultural planting includes a mounting frame 1, which is an inverted U-shaped structure. A crushing bracket 2 is fixedly connected to the outer wall of one side of the mounting frame 1. The crushing bracket 2 is a hollow columnar structure with one side open and is arranged horizontally for crushing incoming soil blocks. A connecting bracket 3 is fixedly connected to the outer wall of the other side of the mounting frame 1 for connecting to the tail traction mechanism of the tractor. A soil loosening component 4 is rotatably connected to the inner ring side wall of the mounting frame 1 for turning the soil to achieve the purpose of loosening the soil. A first walking wheel 5 is symmetrically rotatably connected to the outer ring side wall of the mounting frame 1. A shaking component 6 is fixedly installed on the side walls at both ends of the crushing bracket 2. The shaking component 6 is used to drive the components on the crushing bracket 2 to shake, so that the soil blocks can be fully crushed and after crushing To shake it off, a driving component 7 is fixedly connected to the outer wall of one side of the crushing bracket 2, and the driving component 7 is used to drive the shaking component 6 to operate. A transmission component 8 is fixedly installed on the connecting bracket 3, and the transmission component 8 is connected to the output shaft of the tractor, and is used to drive the loosening component 4 to operate. A protective shell 9 is fixedly connected to the bottom surface of the mounting frame 1 and the connecting bracket 3, and the protective shell 9 is used to protect the transmission component 8 to prevent soil from entering and affecting the transmission, thereby ensuring the good operation of the loosening component 4. A spray component 10 is symmetrically fixedly connected to the side wall of the protective shell 9, which is used to moisten the dry soil to facilitate the turning of the loosening component 4. A water tank 20 is symmetrically fixedly installed on the top surface of the connecting bracket 3. The water tank 20 is filled with water for spraying, and it is connected to the spray component 10 through a pipeline.

[0023] When loosening the soil for agricultural planting, the device is connected to the rear traction mechanism of the tractor through the connecting bracket 3, and its output shaft is connected to the transmission component 8, so that power can be transmitted to the loosening component 4, and the spray component 10 is opened and closed according to the dryness of the soil. When the soil is too dry and the loosening depth of the loosening component 4 does not meet the planting requirements, the soil is properly moistened by the spray component 10, so as to facilitate the turning of the loosening component 4, and the dust raised by the loosening component 4 when operating on dry soil can be reduced by spraying.

[0024] When the loosening component 4 is difficult to turn over the dry soil, or collides with stones in the soil, it can buffer the force acting on the loosening knife through its own structure to prevent the loosening knife from being broken due to excessive force. When the dry soil is moistened by the spray component 10, the loosening component 4 can turn over the soil and drive the soil and stones to be thrown backwards. The thrown soil and stones enter the crushing bracket 2, and the soil blocks collide with the inner wall of the crushing bracket 2, so that the soil blocks are broken and refined, and then fall down with the stones and are screened. The refined soil is screened out, and the stones are collected, so that the stones in the soil can be removed during the loosening process to avoid the continued existence of stones, which causes the loosening knife to collide with them during subsequent loosening.

[0025] The loosening assembly 4 includes a main shaft 41 rotatably connected to the inner ring side wall of the mounting frame 1 , a plurality of rotary cutter mechanisms 42 are symmetrically fixedly connected to the outer wall of the main shaft 41 , and a first bevel gear 43 is fixedly connected to the middle of the outer wall of the main shaft 41 .

[0026] The rotary knife mechanism 42 includes a buffer plate 421 fixedly connected to the outer wall of the main shaft 41, and a plurality of arc grooves 422 are circumferentially opened on the side walls at both ends of the buffer plate 421. The plurality of arc grooves 422 on the same side are arranged in a circular array, and a first guide rod 423 is fixedly connected inside each arc groove 422. A cutter head 424 is slidably connected to the side wall of each first guide rod 423. The cutter head 424 is elastically connected to the inner cavity side wall of the arc groove 422 by a first spring 425, and the first guide rod 423 runs through the inner ring of the first spring 425. The first spring 425 is a high-strength spring. When the turned soil is too dry or the cutter head 424 collides with a stone and is subjected to a large force, the cutter head 424 will deflect to avoid breakage due to excessive force.

[0027] A plurality of scrapers 426 are fixedly connected to the positions of the main shaft 41 corresponding to the plurality of cutter heads 424 , and are used to scrape off the soil remaining on the cutter heads 424 .

[0028] The transmission assembly 8 includes a fixed sleeve 81 fixedly connected to the connecting bracket 3, and a transmission shaft 82 is rotatably connected inside the fixed sleeve 81. One end of the transmission shaft 82 is fixedly connected to the output shaft of the tractor, and the other end of the transmission shaft 82 is fixedly connected to a second bevel gear 83. The second bevel gear 83 is meshed with the first bevel gear 43. The transmission shaft 82 is driven to rotate by the output shaft of the tractor, and then the second bevel gear 83 can be driven to rotate, so that the power of the output shaft is transmitted to the loosening assembly 4.

[0029] Specifically, when in use, the connecting bracket 3 is connected to the rear traction mechanism of the tractor, and the transmission shaft 82 is driven to rotate through the output shaft of the tractor, which can then drive the second bevel gear 83 to rotate. Under the meshing action of the second bevel gear 83 and the first bevel gear 43, power is transmitted to the main shaft 41 to rotate it, thereby driving the multiple rotary knife mechanisms 42 on its side walls to rotate, turning the soil to achieve the effect of loosening the soil. When the soil is relatively dry and difficult to turn, or when the rotary knife mechanism 42 collides with stones in the soil, the cutter head 424 is subjected to a large force and deflects along the arc groove 422 and compresses the first spring 425, wherein the first spring 425 is a high-strength spring, and the cutter head 424 will not deflect when the force is small, thereby being able to buffer the force applied to the cutter head 424 to prevent it from being broken due to excessive force.

[0030] In order to solve the technical problem that the loosening device cannot handle the stones in the soil, and the soil needs to be loosened every once in a while in agricultural planting, resulting in the loosening knife still colliding during the subsequent loosening, such as Figure 6 - Fig.10 As shown, the following preferred technical solutions are provided: A sieve plate 21 is rotatably connected to the inner bottom wall of the crushing bracket 2, which is used to screen the soil after the soil blocks are crushed. During the planting process, loosening the soil is required at regular intervals. The sieve plate 21 can collect the stones inside after loosening the soil once, and take them out for treatment after loosening the soil, so as to avoid the stones from continuing to exist in the farmland soil, which is not conducive to the subsequent loosening of the soil. A crushing plate 22 is slidably connected to the inner side wall of the crushing bracket 2. The crushing plate 22 is inclined, and a plurality of convex thorns 23 are provided on the side wall of the crushing plate 22. The soil blocks thrown out by the loosening component 4 enter the crushing bracket 2 and collide with the crushing plate 22. Under the action of the convex thorns 23, the larger soil blocks are broken and refined, and then roll from the crushing plate 22 to the sieve plate 21.

[0031] The shaking assembly 6 includes a connecting seat 61 which is symmetrically fixedly connected to the outer walls on both sides of the crushing bracket 2. A movable groove 611 is opened on the side wall of each connecting seat 61. A second guide rod 62 is fixedly connected to the inner side wall of each movable groove 611. A slider 63 is slidably connected to the outer wall of the second guide rod 62. The slider 63 is elastically connected to the inner side wall of the movable groove 611 through a second spring 64, and the second guide rod 62 runs through the inner circle of the second spring 64. The slider 63 can slide along the second guide rod 62 and drive the second spring 64 to deform.

[0032] The shaking assembly 6 also includes tripods 65 fixedly connected to the side walls of the two sliders 63, one side outer wall of each tripod 65 is fixedly connected to the back side of the crushing plate 22, and a resist plate 66 is fixedly connected between the two tripods 65. By pushing the resist plate 66, the tripods 65 on both sides and the crushing plate 22 connected to the tripods 65 can be driven to move synchronously. At this time, the slider 63 slides along the second guide rod 62 and compresses the second spring 64. When the force on the resist plate 66 is removed, under the action of the elastic force of the second spring 64, the slider 63 drives the tripod 65 to move so that the resist plate 66 and the crushing plate 22 are reset, thereby having a shaking effect on the crushing plate 22.

[0033] The driving assembly 7 includes an inclined plate 71 fixedly connected to the outer wall of one side of the crushing bracket 2. The bottom end of the inclined plate 71 is a concave structure. A first driven shaft 72 is rotatably connected to the side wall of the concave structure at the bottom of the inclined plate 71. Both ends of the first driven shaft 72 are fixedly connected to second travel wheels 73. A plurality of cams 74 are fixedly connected to the side wall of the first driven shaft 72. The side walls of the plurality of cams 74 slide against the side walls of the abutment plate 66. During the movement of the loosening device, the second travel wheel 73 contacts the ground and rotates, thereby driving the first driven shaft 72 to rotate, so that the plurality of cams 74 can periodically lift the abutment plate 66, thereby driving the shaking assembly 6 to operate and shake the crushing plate 22.

[0034] Specifically, during the movement of the loosening device, the second traveling wheel 73 contacts the ground and rotates, so that the first driven shaft 72 drives the multiple cams 74 fixedly connected to its side wall to rotate. The side walls of the cams 74 abut against the abutment plate 66, so during the rotation process, it can intermittently push the abutment plate 66 upward. In the process that the force of the cams 74 on the abutment plate 66 increases from zero to the maximum, the abutment plate 66 is pushed and drives the tripods 65 on both sides and the crushing plates 22 connected to the tripods 65 to move synchronously, and the slider 63 moves along the second guide rod 62 The second spring 64 is slid and compressed. With the rotation of the cam 74, in the process that its force on the abutment plate 66 gradually decreases to zero, the second spring 64 releases its elastic force to drive the slider 63 to reset, thereby resetting the crushing plate 22 and the abutment plate 66. This reciprocating movement can have a shaking effect on the crushing plate 22, so that the soil blocks collide with the crushing plate 22 and are crushed and shaken off. At the same time, the stones in the soil roll down to the screen plate 21 for collection, so that the stones in the soil can be collected, and the screen plate 21 can be opened for processing after the loosening of the soil is completed.

[0035] In order to solve the problem that when the soil is relatively dry, although the scarifier can turn the soil, the scarification depth often does not meet the planting requirements, resulting in the need to repeatedly scarify the soil, which is inconvenient. Fig.11 As shown, the following preferred technical solutions are provided: The bottom surface of the connecting bracket 3 is symmetrically fixedly connected with the supporting legs 31, and the side walls of the two supporting legs 31 are rotatably connected with the second driven shaft 32, and both ends of the second driven shaft 32 are fixedly connected with the third running wheels 33; The spray assembly 10 includes two connecting plates 101 symmetrically fixedly connected to the side walls of the support legs 31, and an arc-shaped baffle 102 is fixedly connected to one side outer wall of each connecting plate 101. A plurality of nozzles 103 are fixedly connected through the positions corresponding to the plurality of rotary knife mechanisms 42 on the side walls of each arc-shaped baffle 102, and each nozzle 103 is connected to the interior of the water tank 20 through a hose 104.

[0036] Specifically, when the soil is relatively dry, the blade head 424 of the rotary blade mechanism 42 is often unable to extend a sufficient distance, resulting in the loosening depth failing to meet the planting requirements. At this time, by filling the water tank 20 with spray water and opening the connection port at the bottom thereof, water can enter the hose 104. In the loosening process, the soil to be turned over by the rotary blade mechanism 42 can be properly moistened through multiple nozzles 103, thereby ensuring that the loosening depth meets the planting requirements. At the same time, it can also prevent the rotary blade mechanism 42 from raising large dust when operating on dry soil, which may have an adverse effect on the health of the workers.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
