Description

Technical Field

[0001] The utility model relates to the technical field of soil improvement, and more specifically to an integrated machine for returning crop straw to fields and improving soil. Background Art

[0002] Soil improvement is crucial for protecting agricultural production, the ecological environment, and water resources. Good soil quality is the foundation of agricultural production, but long-term, inappropriate management and excessive use of chemical fertilizers and pesticides have led to a decline in soil quality. Soil improvement can restore soil fertility and water retention, improve crop yields and quality, and safeguard the sustainable development of agricultural production. Furthermore, soil improvement contributes to maintaining food security, promoting sustainable economic and social development, protecting the ecological environment, and improving crop quality, thereby generating greater economic benefits for rural residents.

[0003] Chinese Patent Authorization Announcement No.: CN213427101U provides a device for crushing and returning crop straw to the field. This solution uses two sets of belt conveyors to squeeze and convey the straw at the feed port, which avoids the risks of manual feeding and improves the safety of use. The racks on the two sets of belt conveyors are staggered, and the racks are used to bite the straw, thereby improving the conveying capacity of the belt conveyor. Through the threaded transmission of the screw rod and the slider, the slider slides up and down along the slide groove, and the slider drives the second crushing roller to approach or move away from the first crushing roller, thereby adjusting the distance between the first crushing roller and the second crushing roller to obtain the required straw particle size. It is easy to adjust and greatly improves the working capacity of the device for crushing crop straw to the field. However, there are still the following defects in the specific implementation process: after the device crushes the straw, it is unable to turn the crushed straw into the soil.

[0004] Therefore, in order to solve the above problems, a machine integrating crop straw return to field and soil improvement is proposed. Utility Model Content

[0028] Example:

[0029] See also Figure 1-5 A machine for returning crop straw to the field and improving soil includes a mounting plate 1, a fertilizer box 2 is fixedly connected to the upper end of the mounting plate 1, a plurality of fertilizer pipes 3 are fixedly connected to the lower end of the fertilizer box 2, two mounting blocks 4 are fixedly connected to the lower end of the mounting plate 1, and rotating wheels 5 are rotatably connected to the inner surfaces of the two mounting blocks 4, a landfill mechanism 6 is fixedly connected to the inner surface of the rear side of the mounting plate 1, and a crushing mechanism 7 is fixedly connected to the front end of the mounting plate 1.

[0030] This solution uses a crushing mechanism 7 to crush the straw remaining after the harvest of crops. When the machine moves forward, a fertilizer box 2 and a plurality of fertilizer pipes 3 are used to add fertilizer to the crushed straw. Then, a landfill mechanism 6 is used to deep-plow the soil in time so that the mixture of crushed straw and fertilizer can be buried under the turned-over soil, which can effectively improve the fertility of the soil.

[0031] See also Figure 1-2 The landfill mechanism 6 includes a positioning rod 61 and a rotating seat 67. The left and right ends of the positioning rod 61 are fixedly connected to the inner surface of the rear side of the mounting plate 1. The upper end of the rotating seat 67 is fixedly connected to the lower end of the mounting block 4 located at the rear side. The outer surface of the positioning rod 61 is rotatably connected to a rotating tube 62. The outer surface of the rotating tube 62 is fixedly connected to a plurality of plow rods 63. The inner surfaces of the plurality of plow rods 63 are commonly fixedly connected to a fixed rod 64. The outer surface of the fixed rod 64 is rotatably connected to a rotating seat 1 65. The outer surface of the rotating seat 2 67 is rotatably connected to a hydraulic cylinder 66. The output end of the hydraulic cylinder 66 is rotatably connected to the outer surface of the rotating seat 1 65.

[0032] This solution starts the hydraulic cylinder 66 and allows the hydraulic cylinder 66 to control the plowing depth of several plow bars 63 in cooperation with the rotating seat 1 65 and the rotating seat 2 67. When the hydraulic cylinder 66 extends outward, the several plow bars 63 will deflect upward with the positioning rod 61 as the axis in cooperation with the fixed rod 64 and the rotating tube 62. This is suitable for when the machine is idle. When the hydraulic cylinder 66 contracts inward, the several plow bars 63 will deflect downward with the positioning rod 61 as the axis in cooperation with the fixed rod 64 and the rotating tube 62, making it easier for several plow bars 63 to penetrate into the soil. When the machine runs forward, the deep soil can be turned out.

[0033] See also Figure 3-5 The crushing mechanism 7 includes a support plate 71, two positioning plates 72 are fixedly connected to the upper end of the support plate 71, and the ends of the two positioning plates 72 close to each other are fixedly connected to a driving assembly 73. The front end of the support plate 71 is fixedly connected to a hanging ring 74, the lower end of the support plate 71 is fixedly connected to a baffle 75, and the inner surface of the baffle 75 is fixedly connected to a crushing assembly 76.

[0034] The driving assembly 73 includes a motor 731, the output end of the motor 731 is fixedly connected to the bevel gear set 732 through a coupling, the inner surface of the bevel gear set 732 is fixedly connected to the transmission shaft 733, the outer surface of the transmission shaft 733 is fixedly connected to the transmission member 734, the outer surface of the transmission member 734 is fixedly connected to gear 1 736, the outer surface of gear 1 736 is meshed with the outer surface of gear 2 761, the left and right ends of the transmission shaft 733 are connected to the outer shell 735 for common rotation, and the left and right ends of the outer shell 735 are respectively fixedly connected to the ends of the two positioning plates 72 that are close to each other.

[0035] The crushing assembly 76 includes a second gear 761, and the left and right ends of the second gear 761 are fixedly connected to connecting pieces 762. The inner surfaces of the two connecting pieces 762 are fixedly connected to mounting rods 763. The outer surfaces of the two mounting rods 763 are fixedly connected to a plurality of rotary cutters 764. The outer surfaces of the ends of the two mounting rods 763 that are away from each other are rotatably connected to positioning seats 765. The outer surfaces of the two positioning seats 765 are fixedly connected to the inner surface of the baffle 75.

[0036] This solution connects the hanging ring 74 to an external power source to provide the forward driving force for the machine. With the cooperation of the two rotating wheels 5, the machine can move forward in the field. During the movement, the motor 731 is started, and the bevel gear set 732 transmits the force of the motor 731 to the transmission shaft 733, so that the transmission shaft 733 can rotate. When the transmission shaft 733 rotates, the force will cause gear 1 736 to rotate under the transmission of the transmission member 734. Because the outer surface of gear 1 736 is meshed with the outer surface of gear 2 761, when gear 1 736 rotates, it will drive gear 2 761 to rotate as well. When gear 2 761 rotates, it will drive the two connecting members 762 to rotate together. At this time, the two mounting rods 763 located on the inner surfaces of the two connecting members 762 will also rotate with the cooperation of the two positioning seats 765, which can make the several rotary cutters 764 located on the two mounting rods 763 rotate quickly, thereby breaking the straw left after the crops are harvested.

[0037] It should be noted that the specific installation method of the motor 731 and the hydraulic cylinder 66, the circuit connection method, the oil circuit connection method and the control method in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0038] Working principle: In agricultural planting, it is necessary to use a machine to tidy up the farmland before planting crops, so as to facilitate the planting of crops and improve the fertility of the soil. When using the machine, the hanging ring 74 is connected to the external power to serve as the driving force for the machine to move forward. With the cooperation of the two rotating wheels 5, the machine can move forward in the field. Before crushing the straw, the hydraulic cylinder 66 is started first. When the hydraulic cylinder 66 is retracted inward, the plurality of plow rods 63 will deflect downward with the positioning rod 61 as the axis under the cooperation of the fixed rod 64 and the rotating tube 62, so that the plurality of plow rods 63 can penetrate into the soil. When the machine moves forward, the deep soil can be turned out. Then, during the movement of the machine, the fertilizer box 2 and the plurality of fertilizer pipes 3 are controlled to cooperate to spread fertilizer downward and start the motor 73. 1. Let the bevel gear set 732 transmit the force of the motor 731 to the transmission shaft 733, so that the transmission shaft 733 can rotate. When the transmission shaft 733 rotates, the force will be transmitted by the transmission member 734 to cause gear 1 736 to rotate. When gear 1 736 rotates, it will drive gear 2 761 to rotate as well. When gear 2 761 rotates, it will rotate with the two connecting members 762. At this time, the two mounting rods 763 located on the inner surface of the two connecting members 762 will also rotate with the cooperation of the two positioning seats 765, which can make the multiple rotary cutters 764 located on the two mounting rods 763 rotate quickly, breaking up the straw left after the crops are harvested, and after the deep soil is turned over, it can just fill the broken straw and the spread fertilizer below.

[0039] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
