Description

Technical Field

[0001] The present invention relates to the technical field of fertilizing machinery, and particularly to an agricultural organic fertilizer applicator. Background Art

[0002] Organic fertilizer is a natural fertilizer made from biomass such as animal and plant residues and excreta through fermentation and decomposition or physical processing.

[0003] Due to different fermentation times and different treatment processes, the humidity of organic fertilizers varies. When using mechanical equipment for fertilization, different humidity states of organic fertilizers result in different fertilization effects. For example, high-humidity organic fertilizers are viscous and prone to caking, easily clogging machine pipelines or spreading devices, while semi-dry organic fertilizers may form local clumps due to uneven humidity, affecting the spreading uniformity. All of the above situations are likely to cause uneven fertilization.

[0004] Therefore, the present invention provides an agricultural organic fertilizer applicator that can be applicable to organic fertilizers with different humidities and achieve uniform fertilization without easy clogging. Summary of the Invention

[0005] In view of the problem in the above or existing technologies that it is difficult to achieve uniform fertilization of organic fertilizers under different humidities, the present invention is proposed.

[0006] Therefore, the object of the present invention is to provide an agricultural organic fertilizer applicator.

[0007] To solve the above technical problems, the present invention provides the following technical solution: An agricultural organic fertilizer applicator includes a material conveying channel, which includes a support shaft sleeve and an eccentric shaft cylinder provided on the support shaft sleeve, and further includes a first extrusion hole provided on the eccentric shaft cylinder; a screw feeding mechanism rotatably provided in the material conveying channel; a crushing mechanism rotatably provided outside the material conveying channel; the rotation axis of the screw feeding mechanism is coaxial with the axis of the support shaft sleeve.

[0017] Advantages of the agricultural organic fertilizer applicator of the present invention: Since the rotation axis of the auger feeding mechanism is coaxial with the axis of the support bushing, and the axis of the support bushing is different from the axis of the eccentric shaft cylinder, during the operation of the equipment, when the eccentric shaft cylinder rotates around the axis of the support bushing, the distance between its inner surface and the auger feeding mechanism will continuously change, forming extrusion of the organic fertilizer. Cooperating with the auger feeding mechanism continuously feeding fertilizer into the eccentric shaft cylinder, the fertilizer will continuously be extruded from the first extrusion holes as the eccentric shaft cylinder rotates, achieving uniform fertilization. Moreover, for caked fertilizer, the movement of the eccentric shaft cylinder can crush and extrude the caked fertilizer. At the same time, for fertilizer with high humidity and strong adhesiveness, the movement of the eccentric shaft cylinder can achieve continuous extrusion operation, causing the fertilizer to be extruded from each first extrusion hole, achieving uniform fertilization. When the eccentric shaft cylinder rotates, due to its eccentric setting, the position where the fertilizer drops will also change as the eccentric shaft cylinder rotates, and the eccentric movement is convenient for throwing off the extruded fertilizer, avoiding the occurrence of adhesion phenomenon.

[0027] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation modes of the present invention with reference to the accompanying drawings of the specification.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation mode of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1 to 7 , which is the first embodiment of the present invention. This embodiment provides an agricultural organic fertilizer applicator, including a feeding channel 1, which includes a support bushing 11 and an eccentric shaft cylinder 12 provided on the support bushing 11. It also includes a first extrusion hole 13 provided on the eccentric shaft cylinder 12. Support bushings 11 are provided at both ends of the eccentric shaft cylinder 12. The axis of the support bushing 11 and the axis of the eccentric shaft cylinder 12 are different. A plurality of first extrusion holes 13 are provided and are evenly distributed on the outer wall surface of the eccentric shaft cylinder 12.

[0031] The screw feeding mechanism 2 is rotatably arranged in the feeding channel 1. By the rotation of the screw feeding mechanism 2, organic fertilizer can be conveyed in the feeding channel 1, conveyed into the eccentric shaft cylinder 12, and discharged from the first extrusion hole 13.

[0032] The crushing mechanism 3 is rotatably arranged outside the material conveying channel 1; the rotation of the crushing mechanism 3 can perform crushing operations on the soil.

[0033] The rotation axis of the auger feeding mechanism 2 is coaxial with the axis of the support sleeve 11.

[0034] During use, the device is connected to an agricultural machine. By driving the crushing mechanism 3 to rotate, soil crushing is achieved. While the soil is being crushed, the auger feeding mechanism 2 is controlled to rotate to convey organic fertilizer into the inside of the eccentric shaft cylinder 12. At the same time, the material conveying channel 1 is controlled to rotate together. Since the rotation axis of the auger feeding mechanism 2 is coaxial with the axis of the support sleeve 11, and the axis of the support sleeve 11 is different from the axis of the eccentric shaft cylinder 12, during the operation of the equipment, when the eccentric shaft cylinder 12 rotates with the axis of the support sleeve 11 as the rotation axis, the distance between its inner surface and the auger feeding mechanism 2 will continuously change, forming extrusion of the organic fertilizer. With the auger feeding mechanism 2 continuously conveying fertilizer into the inside of the eccentric shaft cylinder 12, the fertilizer will continuously be extruded from the inside of the first extrusion holes 13 as the eccentric shaft cylinder 12 rotates, achieving uniform fertilization. Moreover, for agglomerated fertilizer, the movement of the eccentric shaft cylinder 12 can roll and crush the agglomerated fertilizer. At the same time, for fertilizer with higher humidity and stronger adhesiveness, the movement of the eccentric shaft cylinder 12 can achieve continuous extrusion operations, causing the fertilizer to be extruded from each of the first extrusion holes 13, achieving uniform fertilization. When the eccentric shaft cylinder 12 makes a rotational motion, due to its eccentric setting, the position where the fertilizer drops will also change as the eccentric shaft cylinder 12 rotates, and the eccentric movement is convenient for throwing off the extruded fertilizer, avoiding the occurrence of adhesion phenomena.

[0035] Specifically, the auger feeding mechanism 2 includes a drive shaft 21 rotatably arranged inside the support sleeve 11, and a thick shaft 22 arranged at the end of the drive shaft 21. The outer wall of the thick shaft 22 is provided with a first auger blade 23. One end of the thick shaft 22 is provided with a thin shaft 24, and the outer wall of the thin shaft 24 is provided with a second auger blade 25. The drive shaft 21, the thick shaft 22, and the thin shaft 24 are connected in sequence. The organic fertilizer feeding part is located at the position where the thin shaft 24 is located. The outer wall dimension of the second auger blade 25 matches the inner wall dimension of the support sleeve 11, and the outer wall radius of the first auger blade 23 is slightly smaller than the minimum distance from the inner wall of the eccentric shaft cylinder 12 to the axis of the support sleeve 11.

[0036] Furthermore, the crushing mechanism 3 includes a support frame 31 rotatably arranged on the outer wall of the support sleeve 11, and a support disk 32 rotatably arranged on the outer wall of the support frame 31. The support disk 32 is provided with crushing knives 33. The support frame 31 is used to connect to an agricultural machine, and the device is installed on the agricultural machine through the support frame 31. A plurality of crushing knives 33 are arranged in a circumferential array on the outer wall of the support disk 32. Refer to Figure 5, the crushing knife 33 is inclined. When the support disk 32 rotates, the inclined crushing knife 33 can also guide the crushed soil into the middle of the crushing mechanism 3.

[0037] One end of the support shaft sleeve 11 is provided with a first output wheel 14; one end of the drive shaft 21 is provided with a second output wheel 26; one end of the support disk 32 is provided with a third output wheel 34. The first output wheel 14, the second output wheel 26, and the third output wheel 34 can be one of a gear, a pulley, and a sprocket, and can transmit power. They are driven by a driving device such as a driving motor or a diesel engine on an agricultural machine to control the rotation of the support shaft sleeve 11, the drive shaft 21, and the support disk 32.

[0038] Preferably, it further includes a feed hopper 7 provided on the support frame 31. The feed hopper 7 is rotatably connected to the support shaft sleeve 11, and the feed hopper 7 is used to add organic fertilizer.

[0039] During use, organic fertilizer is added through the feed hopper 7. The drive shaft 21 is driven to rotate by the second output wheel 26, so that the first auger blade 23 and the second auger blade 25 rotate. The second auger blade 25 conveys the organic fertilizer into the eccentric shaft cylinder 12, and the first auger blade 23 sends the organic fertilizer to various parts of the eccentric shaft cylinder 12. The support disk 32 is driven to rotate at a high speed by the third output wheel 34, the soil is chopped by the crushing knife 33, the support shaft sleeve 11 is driven to rotate by the first output wheel 14, and then the eccentric shaft cylinder 12 moves. During the movement of the eccentric shaft cylinder 12, the fertilizer located between the eccentric shaft cylinder 12 and the first auger blade 23 is continuously extruded, so that it is extruded from the first extrusion hole 13. The agglomerated part can be crushed by the extrusion of the eccentric shaft cylinder 12 and the rotation of the first auger blade 23 to achieve the effect of preventing blockage. Finally, the fertilizer is evenly spread into the crushed soil through the first extrusion hole 13, and it can be applied to organic fertilizers with different humidities.

[0040] Embodiment 2, refer to Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, it further includes a limiting mechanism 4; the limiting mechanism 4 includes a fixed arm 41 and a first limiting frame 42 provided on the fixed arm 41; the fixed arm 41 is fixedly provided on the support frame 31; it further includes a cutting member 5 rotatably provided on the eccentric shaft cylinder 12; the cutting member 5 includes a movable sleeve 51 rotatably provided on the eccentric shaft cylinder 12 and a second extrusion hole 52 provided on the movable sleeve 51. An upper swing arm 53 is provided on the movable sleeve 51, and an upper slider 54 rotatably provided on the upper swing arm 53 is further included; the upper slider 54 is slidably connected to the first limiting frame 42.

[0041] It should be noted that there are two fixed arms 41 arranged symmetrically, and there are two upper swing arms 53 arranged symmetrically on the outer wall of the movable sleeve 51. The second extrusion holes 52 and the first extrusion holes 13 are arranged in one-to-one correspondence.

[0042] During the movement of the eccentric shaft cylinder 12, since the upper slider 54 and the first limit frame 42 are slidingly connected, the eccentric shaft cylinder 12 will produce relative rotation with the movable sleeve 51, and when the eccentric shaft cylinder 12 moves, the movable sleeve 51 will perform a circular motion. When the movable sleeve 51 performs a circular motion, the upper swing arm 53 will be deflected with the upper slider 54, and the upper slider 54 slides in the first limit frame 42.

[0043] It should be noted that when relative rotation occurs between the eccentric shaft cylinder 12 and the movable sleeve 51, the second extrusion hole 52 and the first extrusion hole 13 will be intermittently aligned. Therefore, when the second extrusion hole 52 and the first extrusion hole 13 are misaligned, the first auger blade 23 cooperates with the rotation of the second auger blade 25 to fill the eccentric shaft cylinder 12 with organic fertilizer. When the second extrusion hole 52 and the first extrusion hole 13 are aligned, the organic fertilizer in the eccentric shaft cylinder 12 can be evenly extruded. At the same time, due to the relative movement of the second extrusion hole 52 and the first extrusion hole 13, an extrusion and cutting effect can be formed to crush the agglomerated organic fertilizer, and at the same time, it can also prevent the organic fertilizer with high viscosity from adhering to the surface of the eccentric shaft cylinder 12.

[0044] Specifically, the cutting member 5 further includes a lower swing arm 55 disposed on the movable sleeve 51 , on which a lever 551 is disposed. Two lower swing arms 55 are provided and symmetrically disposed on the outer wall of the movable sleeve 51 , and the lever 551 is connected to the two lower swing arms 55 .

[0045] The rest of the structure is the same as that of Example 1.

[0046] When the eccentric shaft cylinder 12 rotates, the movable sleeve 51 will make a circular motion as a whole. Since the upper slider 54 is slidably arranged in the first limit frame 42, when the movable sleeve 51 makes a circular motion, the lower swing arm 55 thereon will make a deflection motion, so that the lower swing arm 55 drives the lever 551 to move, and the soil is pushed away, so that the organic fertilizer can be mixed with the crushed soil more evenly.

[0047] Example 3, reference Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, it also includes a mixing piece 6; the mixing piece 6 includes a mixing barrel 61 rotatably arranged on the crushing mechanism 3, and a transverse groove 62 arranged on the mixing barrel 61; the transverse groove 62 is evenly opened on the surface of the mixing barrel 61; a fixing block 56 is provided on the lower swing arm 55, and the fixing block 56 is fixed on the lower swing arm 55.

[0048] Reference Figure 3At this time, the fixed block 56 is inserted into the transverse groove 62 below the mixing barrel 61, and the axis of the eccentric shaft barrel 12 is located directly below the axis of the supporting sleeve 11. When the supporting sleeve 11 rotates counterclockwise, the axis of the eccentric shaft barrel 12 will make a circular motion along the axis of the supporting sleeve 11. Therefore, during the initial rotation, the fixed block 56 will drive the mixing barrel 61 to rotate at a certain angle. At the same time, as the rotation angle increases, the depth of the fixed block 56 inserted into the transverse groove 62 will gradually decrease until the supporting sleeve 11 rotates ninety degrees, at which time the fixed block 56 just disengages from the insertion of the transverse groove 62 below. At this time, the axis of the eccentric shaft barrel 12 and the axis of the supporting sleeve 11 are at the same height, the upper slider 54 is aligned with the transverse groove 62 above the mixing barrel 61, and the lower swing arm 55 is at the maximum deflection angle.

[0049] As the support sleeve 11 continues to rotate, in the process of the support sleeve 11 rotating from ninety degrees to one hundred and eighty degrees, the upper slider 54 slides up and inserts into the transverse groove 62, and the fixed block 56 moves away from the lowest transverse groove 62, until the support sleeve 11 rotates to one hundred and eighty degrees, the axis of the eccentric shaft tube 12 is located directly above the axis of the support sleeve 11, the fixed block 56 is at a maximum distance from the lowest transverse groove 62, and the upper slider 54 is inserted into the transverse groove 62 to a maximum depth, and the lower swing arm 55 returns to a vertical state.

[0050] As the support sleeve 11 continues to rotate, in the process of the support sleeve 11 rotating from one hundred and eighty degrees to two hundred and seventy degrees, the upper slider 54 is gradually pulled out from the inside of the transverse groove 62, and the fixed block 56 gradually approaches the lowest transverse groove 62, until the support sleeve 11 rotates to two hundred and seventy degrees, the upper slider 54 just disengages from the transverse groove 62, the fixed block 56 just aligns with the lower transverse groove 62, and the lower swing arm 55 is at the maximum deflection angle. It should be noted that the directions of the maximum deflection angles when the support sleeve 11 rotates ninety degrees and when it rotates two hundred and seventy degrees are opposite.

[0051] As the support sleeve 11 continues to rotate, in the process of the support sleeve 11 rotating from 270 degrees to 360 degrees, the upper slider 54 gradually moves away from the upper transverse groove 62, and the depth of the fixed block 56 inserted into the lower transverse groove 62 gradually increases until the support sleeve 11 rotates to 360 degrees and returns to Figure 3 status.

[0052] When the upper slider 54 is inserted into the horizontal groove 62, it can limit the mixing cylinder 61; when the support bushing 11 rotates, it can intermittently push the mixing cylinder 61 to rotate. Therefore, the mixing cylinder 61 can also push the soil inside to facilitate uniform mixing. At the same time, since the mixing cylinder 61 is in an intermittent rotation state, the horizontal groove 62 will continuously switch, so that the crushed soil can enter the mixing cylinder 61 through the horizontal groove 62. The relative rotation between the mixing cylinder 61 and the crushing knife 33 assists in the crushing of the soil and improves the effect of the crushing mechanism 3 in crushing the soil.

[0053] Specifically, an upper push plate 541 is provided on the upper slider 54; a lower push plate 561 is provided on the fixed block 56. The settings of the upper push plate 541 and the lower push plate 561 facilitate the extrusion of the soil in the horizontal groove 62, so that the crushed soil can enter the mixing cylinder 61.

[0054] Furthermore, it further includes a swinging member 8; the swinging member 8 includes a rotating arm 81 rotatably provided on the outer wall of the support bushing 11, and a second limiting frame 82 provided on the rotating arm 81; the second limiting frame 82 is slidably connected to the fixed block 56. The setting of the swinging member 8 can increase the stability of the lower swing arm 55, and the first limiting frame 42 and the second limiting frame 82 can scrape off the soil adhering to the inner wall of the mixing cylinder 61.

[0055] The remaining structures are the same as those in Embodiment 2.

[0056] During use, the crushing mechanism 3 crushes the soil and moves through the traction device of the agricultural machine. After the crushing knife 33 crushes the soil, the soil can enter the interior of the mixing cylinder 61 through the horizontal groove 62. Through the rotation of the mixing cylinder 61 and the swing of the lower swing arm 55, the soil can be stirred so that the organic fertilizer can be evenly mixed with the soil and fall into the soil interior. While the mixing cylinder 61 rotates intermittently, the upper push plate 541 and the lower push plate 561 intermittently extrude the soil stuck in the horizontal groove 62. Therefore, the upper push plate 541 dredges the horizontal groove 62 above the mixing cylinder 61 to keep the horizontal groove 62 in the forward direction from being blocked, and the lower push plate 561 extrudes the soil inside the mixing cylinder 61 from the horizontal groove 62 to discharge part of the soil in the mixing cylinder 61 and avoid carrying soil and organic fertilizer during movement.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
