Description

Technical Field

[0001] The present application belongs to the technical field of agricultural machinery, and more specifically, relates to a controllable variable tillage width loosening device. Background Art

[0002] With the accelerated advancement of urbanization in my country, urban micro-agriculture, which can satisfy the pastoral pleasure of growing green fruits and vegetables in fragmented urban spaces while producing green, healthy and pollution-free food, has developed rapidly. The London government in the United Kingdom has tried to transform rooftops, balconies, abandoned factories, and infrequently used barges into planting areas, calling it the "Capital Planting Plan." Residents of Paris, France, also grow strawberries, tomatoes and other fruits and vegetables on their balconies. The development of urban micro-agriculture is becoming increasingly common internationally.

[0003] At present, there is almost no professional machinery designed and developed for urban micro-agriculture in the domestic market. Therefore, there is a great demand for horticultural crop facility production equipment, especially production equipment designed for automatic soil loosening and weeding operations required for soil cultivation of fruits and vegetables on roof balconies.

[0004] CN201320186688.8 discloses a variable tillage width knife and rake device for a micro-tillage machine, but it cannot realize automatic control of the tillage width and can only be manually changed. The adjustment is relatively cumbersome and it cannot be operated in a vegetable basin. CN201921988396.X discloses an adaptive variable tillage width knife holder for a micro-tillage machine, but it can only passively change the tillage width by changing the rotation speed and cannot achieve precise and active control of the tillage width through a mechanical structure transmission method. It cannot perfectly adapt to corners or special-shaped vegetable basins. Summary of the invention

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0029] like Figure 1 As shown, a controllable variable tillage amplitude loosening device 100 includes at least one variable amplitude mechanism, the variable amplitude mechanism includes a central rod 10, and a first variable amplitude component 20 and a second variable amplitude component 30 are rotatably connected to the outer circumference of the central rod 10, respectively. A power connection component is also installed on the outer circumference of the central rod 10, one end of the central rod 10 is connected to a power output source device, and the other end of the central rod 10 is directly connected to the power connection component or connected to the power component through a connecting rod or the like. The first variable amplitude component 20 and the second variable amplitude component 30 are both connected to the central rod 10 through the power connection component on the central rod 10 to transmit the power on the central rod 10 to the first variable amplitude component 20 and the second transmission component, and the first variable amplitude component 20, the second variable amplitude component 30 and the central rod 10 are all connected with a tillage component 40.

[0030] The central pole 10 is connected to the power output source device, and the power connection component on the central pole 10 can be connected to the first amplitude variation component 20 and the second amplitude variation component 30 in the amplitude variation mechanism, so as to provide a driving power source for the tillage components 40 connected to the central pole 10 and the tillage components 40 on the first amplitude variation component 20 and the second amplitude variation component 30. At the same time, the first amplitude variation component 20 and the second amplitude variation component 30 can rotate with the central pole 10 to change the positions of the first amplitude variation component 20 and the second amplitude variation component 30 relative to the central pole 10, so that the positions of the tillage components 40 on the first amplitude variation component 20 and the second amplitude variation component 30 can be adjusted relative to the tillage components 40 connected to the central pole 10, thereby realizing the tillage and tillage width adjustment of the amplitude variation mechanism.

[0031] Furthermore, the first amplitude-changing assembly 20 and the second amplitude-changing assembly 30 are both rotatably connected around the central rod 10, and the rotation angle range of the first amplitude-changing assembly 20 and the second amplitude-changing assembly 30 relative to the central rod 10 is 0-90°, thereby adjusting the position variation range of the two amplitude-changing assemblies relative to the central rod 10, so that the tillage width can be adjusted without affecting the work between the various tillage components 40.

[0032] Specifically, the configurations of the first amplitude variation assembly 20 and the second amplitude variation assembly 30 may be as follows: Figure 1 , 2 As shown in Figure 3, the first amplitude change assembly 20 includes a first active rotating component, a first passive rotating component and a connecting piece connecting the first active rotating component and the first passive rotating component, the first active rotating component is connected to the first amplitude change driving device 201 and can rotate axially around the central rod 10, the first passive rotating component includes a first driven component and a tillage component 40 that are transmission-connected to the power connection assembly; the second amplitude change assembly 30 includes a second active rotating component, a second passive rotating component and a connecting piece connecting the second active rotating component and the second passive rotating component, the second active rotating component is connected to the second amplitude change driving device 301 and can rotate axially around the central rod 10, the second passive rotating component includes a second driven component and a tillage component 40 that are transmission-connected to the power connection assembly. The active rotating component on the amplitude change mechanism drives the passive rotating component connected thereto to rotate, and the active rotating component is connected to the amplitude change driving device to provide a power source for the rotation of the amplitude change mechanism, so that the amplitude change mechanism as a whole can rotate around the central rod 10 to achieve the adjustment of the tillage width.

[0033] It should be noted that the first luffing drive device 201 and the second luffing drive device 301 may be stepper motors to more accurately control the rotation angle of each luffing mechanism relative to the central rod 10 .

[0034] Furthermore, the tilling component 40 is a rotary tiller, preferably a vertical tiller, and each tiller is directly or indirectly connected to the variable amplitude mechanism and the central rod 10 in a fastened connection form, which is convenient for replacing the tiller.

[0035] More specifically, with regard to the configuration of the first amplitude variation assembly 20 and the second amplitude variation assembly 30, the manner in which the first active rotating component and the central rod 10 in the first amplitude variation assembly 20 are rotationally connected, and the manner in which the second active rotating component and the central rod 10 in the second amplitude variation assembly 30 are rotationally connected may be the same or different, for example, a manner in which rotation occurs through the engagement of gears with gears, etc. The transmission connection manner of the first passive rotating component and the power connection assembly in the first amplitude variation assembly 20, and the second passive rotating component and the power connection assembly in the second amplitude variation assembly 30 is the same, for example, a transmission connection manner through gear meshing.

[0036] When the first active rotating component and the central rod 10 in the first luffing assembly 20 are connected in rotation and the second active rotating component and the central rod 10 in the second luffing assembly 30 are connected in rotation by gear meshing rotation, and the first passive rotating component and the power connection assembly in the first luffing assembly 20 and the second passive rotating component and the power connection assembly in the second luffing assembly 30 are connected in transmission by gear meshing transmission, the configuration of the luffing mechanism can be as follows: Figure 1 , 2 , 3, specifically:

[0037] The first active rotating component includes a rotating shaft a205 and a gear a204. One end of the rotating shaft 205a is connected to the first variable amplitude driving device 201, and the gear a204 is fixedly sleeved on the outer circumference of the rotating shaft a205. The first passive rotating component includes a support rod a203 and a gear b202. The connecting piece is a connecting sleeve. The gear b202 is fixedly sleeved on the outer circumference of the supporting rod a203. The second active rotating component includes a rotating shaft b305 and a gear c304. One end of the rotating shaft b305 is connected to the second variable amplitude driving device 301, and the gear c304 is fixedly sleeved on the outer circumference of the rotating shaft b305. The second passive rotating component includes a support rod b303 and a gear d302. A gear d302 is fixedly sleeved on the outer circumference of the support rod b303; an upper gear 101 and a lower gear 103 are rotatably sleeved on the outer circumference of the central rod 10 in sequence, and the power connection assembly includes a gear e102 fixedly sleeved on the outer circumference of the central rod 10, and the gear e102 can mesh with the gear b202 and the gear d302. The upper gear 101 and the support rod a203, and the lower gear 103 and the support rod b303 are each connected by a connecting sleeve, the gear a204 meshes with the upper gear 101, and the gear c meshes with the lower gear 103. A tillage component 40 is also installed on each of the support rod a203, the support rod b303 and the central rod 10.

[0038] It should be noted that the gears are preferably cylindrical gears, and each gear can be fixedly mounted or movably mounted with the central rod 10, the support rod, and the rotating shaft through bearings. Figure 4 As shown, one end of the connecting sleeve is movably mounted on the outer periphery of the supporting rod through a bearing, and the other end is directly connected to the upper gear 101 or the lower gear 103 .

[0039] The first variable amplitude driving device 201 drives the gear a204 to rotate, thereby driving the upper gear 101 on the central rod 10 to rotate, and then through the drive of the connecting sleeve, the support rod a203 rotates relative to the central rod 10. Similarly, the second variable amplitude driving device 301 drives the gear c to rotate, thereby indirectly causing the support rod b303 to rotate relative to the central rod 10. In this way, through the rotation of the first variable amplitude driving device 201 and the second variable amplitude driving device 301, the position of the first variable amplitude assembly 20 relative to the central rod 10 and the position of the second variable amplitude assembly 30 relative to the central rod 10 can be adjusted accordingly. The central rod 10 is also connected to the power output source device, and the central rod 10 is meshed with the gear b202 and the gear d302 through the gear e102, so that the first variable amplitude assembly 20, the second variable amplitude assembly 30, and the tillage component 40 on the central rod 10 can be driven to work synchronously through a power device on the central rod 10.

[0040] It should be noted that the first amplitude-changing assembly 20 and the second amplitude-changing assembly 30 can be symmetrically distributed around the central rod 10, that is, the rotating axis a and the support rod a203 in the first amplitude-changing assembly 20 and the rotating axis b and the support rod b303 in the second amplitude-changing assembly 30 are symmetrically distributed relative to the central axis of the central rod 10.

[0041] In the above case, if the rotating and transmitting parts in the luffing mechanism are completely exposed to the external environment, they are very easy to be worn out. Therefore, part of the mechanism is arranged in the housing 50, for example, by: Figure 5 As shown, the controllable variable tillage amplitude loosening device 100 also includes a shell 50, and the first variable amplitude component 20, the second variable amplitude component 30, and the power connection component can be partially accommodated in the cavity of the shell 50, and the shell 50 is provided with a slideway 51 for the first variable amplitude component 20 and the second variable amplitude component 30 to rotate, and the first variable amplitude component 20, the second variable amplitude component 30 and the central rod 10 are all connected to a tillage component 40 after passing through the bottom wall of the shell 50.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
