Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly relates to a tea shoot cutting machine. Background Art

[0002] The propagation methods of tea plants are divided into two types: sexual propagation and asexual propagation. Sexual propagation, also known as seed propagation, usually refers to the propagation method of reproducing offspring in the form of seeds; asexual propagation refers to the propagation method of tea plants under artificial intervention, mainly including methods such as cutting, layering, dividing plants, and grafting; among them, cutting is a main means of asexual propagation of tea plants.

[0003] The main operation process is as follows: From the improved variety mother tea plant, select the current year's new shoots with reddish-brown color in the middle and lower parts, cut a short stem about 3 cm long with a true leaf and an axillary bud at the top; when cutting, quickly dip the cut end of the cutting in the auxin liquid medicine and then carry out cutting, and carry out cutting on the prepared seedbed according to a row spacing of 7-10 cm and a plant spacing of 3-4 cm.

[0004] Currently in China, manual cutting is mainly adopted, and some auxiliary tools are used to improve efficiency. For example:

[0005] The invention patent with the authorization announcement number CN220173854U discloses a plant cutting and seedling raising device, which can complete hole punching, inserting the stem and covering the soil, and has a loosening effect on the soil around the hole, improving the rooting rate. However, due to the relatively simple structure of this device, it can only carry out the cutting and planting of single cutting at a time, and the efficiency of cutting and seedling raising is relatively low.

[0006] The invention patent with the authorization announcement number CN221996131U discloses a garden plant cutting and seedling raising device, which is provided with a plurality of cutting cylinders and can complete the cutting and planting of multiple cuttings at one time. However, after each cutting, it is necessary to supplement the cuttings to the cutting cylinders, and the efficiency is relatively low.

[0007] Therefore, there is a lack of large-scale continuous cutting machines in China. Summary of the Invention

[0015] Further, the seedling pressing drive assembly includes a passive gear b engaged and connected with the passive gear a, and the driving wheels of each seedling pressing device are all connected to the passive gear b through the same second rotating shaft.

[0016] Further, the seedling pressing device further has a second housing, and the limiting seat, the pulley assembly and the connecting rod are all arranged inside the second housing; the bottom end of the downward pressing rod passes through the second housing and is located outside the second housing.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Such as Figure 1 AndFigure 2 As shown in the figure, the present invention provides a specific implementation of a tea tree cutting machine, including a seedling feeding chute 1, a sorting and feeding device 2, a seedling placing device 3, and a seedling pressing device 4 provided on a traveling mechanism 5; for applications such as inserting cuttings or other scenarios that require a downward insertion action.

[0040] This implementation will be described using the insertion of cuttings as the application scenario.

[0041] In this implementation, the seedling feeding chute 1 can be any structure that can complete the function of feeding seedlings, and no specific limitation is made; in this implementation, a pipe with both ends open is selected as the seedling feeding chute 1.

[0042] The seedling feeding chute 1 is used to place cuttings. The setting direction of the seedling feeding chute 1 is such that the discharge port 13 is located below the feed port 12, and the discharge port 13 is directly above the sorting and feeding device 2; so that the cuttings entering the seedling feeding chute 1 can fall into the sorting and feeding device 2 along the seedling feeding chute 1.

[0043] Furthermore, the part of the seedling feeding chute 1 close to the discharge port 13 is vertically arranged, so that the cuttings can enter the sorting and feeding device 2 vertically.

[0044] And since the axillary bud end of the cuttings needs to be downward during the cutting process, when the cuttings are placed in the seedling feeding chute 1, the axillary bud end of the cuttings needs to face the feed port 12 of the seedling feeding chute 1.

[0045] Furthermore, in order to improve the conveying efficiency, this equipment can also be used in conjunction with a special cuttings conveying device, so that the cuttings can enter the seedling feeding chute 1 in an orderly manner. Since this part of the structure is not an essential technical feature for solving the technical problems of this application, the technical personnel of this application can use the conveying equipment existing in the prior art to achieve the relevant functions; therefore, no specific limitation is made on the specific structure of the cuttings conveying device in this application.

[0046] In this implementation, the sorting and feeding device 2 has a sorting wheel 21 and a sorting drive assembly. The sorting drive assembly is drivingly connected to the sorting wheel 21 and is used to drive the sorting wheel 21 to rotate. The rotation plane of the sorting wheel 21 is vertically arranged and is consistent with the traveling direction of the traveling mechanism 5; a plurality of seedling dropping holes 23 are radially and equidistantly arranged on the sorting wheel 21, and the discharge port 13 of the seedling feeding chute 1 is directly opposite and arranged above the sorting wheel 21.

[0047] During the rotation of the sorting wheel 21, the entrances of the seedling dropping holes 23 can be aligned with the discharge port 13 of the seedling feeding chute 1 in sequence; so that the cuttings entering the seedling feeding chute 1 can fall into the seedling dropping holes 23 in sequence through the seedling feeding chute 1.

[0048] Among them, the axillary bud end of the cutting slips downward into the seedling dropping holes 23 of the sorting wheel 21. After the sorting wheel 21 rotates 180°, the axillary bud end of the cutting slips downward into the seedling placing device 3.

[0049] Furthermore, in order to further improve the cutting efficiency, it is necessary to ensure the orderliness of the cutting slips falling from the seedling feeding chute 1 into the sorting wheel 21 and from the sorting wheel 21 into the seedling placing device 3, so that only one cutting slip enters the seedling placing device 3 at a time.

[0050] Therefore, in this embodiment, the diameter of the seedling dropping holes 23 can only accommodate a single cutting slip, so that after the sorting and feeding by the sorting wheel 21, only one cutting slip enters the seedling placing device 3 at a time.

[0051] Furthermore, since the diameter of the seedling dropping holes 23 is relatively small, in order to ensure the accuracy of the cutting slips falling into the seedling dropping holes 23, a conical sleeve body 14 with a large mouth facing upward and a small mouth facing downward is arranged at the discharge port 13 of the seedling feeding chute 1. The diameter of the small mouth of the conical sleeve body 14 is slightly larger than the diameter of the seedling dropping holes 23. And during the rotation of the sorting wheel 21, the inlet of the seedling dropping holes 23 can be aligned with the small mouth of the conical sleeve body 14 in sequence to improve the accuracy of the cutting slips falling into the sorting and feeding device 2.

[0052] Furthermore, the bottom of the conical sleeve body 14 extends downward to form an auxiliary blanking pipe 15, so that the cutting slips fall in a vertical state.

[0053] In this embodiment, the seedling placing device 3 has a seedling placing channel 31 and an alignment mechanism 32 arranged at the bottom of the seedling placing channel 31. The alignment mechanism 32 cooperates with the walking of the walking mechanism 5, so that the cutting slips can be arranged in a straight line on the soil surface and keep in a vertical state.

[0054] The alignment mechanism 32 is provided with a straight seedling arranging groove 33 along the walking direction. The seedling placing channel 31 is vertically arranged, and the inlet of the seedling placing channel 31 can be sequentially aligned with the outlet of each seedling dropping hole 23 to receive the cutting slips. The outlet of the seedling placing channel 31 faces the straight seedling arranging groove 33. The straight seedling arranging groove 33 is used to arrange the falling seedlings in a straight line in sequence and prevent the cutting slips from tipping over, so that the cutting slips keep in a vertical state.

[0055] Under normal circumstances, before the cutting slips are inserted into the soil, the soil will be wetted and become soft. During the falling process of the cutting slips, the axillary bud end at the end of the cutting slips can be inserted into the soil, so that the cutting slips keep in a vertical state.

[0056] Furthermore, the distance between the end of the seedling placing channel 31 and the soil surface is greater than the height of the cutting slips, so that after the end of the cutting slips falling through the seedling placing channel 31 is inserted into the wet soil, there is a gap between the top of the cutting slips and the end of the seedling placing channel 31, avoiding the cutting slips from hindering the movement of the seedling placing channel 31 and preventing the cutting slips from tipping over due to the movement of the seedling placing channel 31.

[0057] Further, in this embodiment, an embodiment of the alignment mechanism 32 is also provided, as shown in the figure:

[0058] The alignment mechanism 32 includes two alignment plates 34 arranged in parallel along the traveling direction. The width sides of the alignment plates 34 are vertically arranged at the bottom of the seedling placing channel 31. The space between the two alignment plates 34 forms a straight seedling row groove 33. The cuttings fall into the straight seedling row groove 33 through the seedling placing channel 31. The two alignment plates 34 exert restrictions on the cuttings to prevent the cuttings from shifting during the falling process, so that multiple cuttings can be arranged in a straight line in sequence along the traveling direction of the traveling mechanism 5.

[0059] Since the diameter of the cuttings is generally 1 - 2 mm, therefore, the gap of the straight seedling row groove 33 needs to be controlled within 2 - 3 mm; and in order to enable the cuttings in the seedling dropping hole 23 to accurately fall into the seedling placing channel 31, the straight drop ratio of the seedling placing channel 31 is larger than that of the seedling dropping hole (generally 2 - 3 times), which makes it difficult for the cuttings in the seedling placing channel 31 to accurately fall into the straight seedling row groove 33.

[0060] Therefore, further, the length sides at the top of the two alignment plates 34 are respectively fixed at the edges on the opposite sides of the opening of the bottom plate of the seedling placing channel 31. The length sides at the bottom of the two alignment plates 34 are inclined towards the middle in the direction from the bottom opening of the seedling placing channel 31 downwards, so as to form a straight seedling row groove 33 passing through the center below the bottom opening of the seedling placing channel 31, making the cross-section of the straight seedling row groove 33 in an inverted conical structure, guiding the falling of the cuttings, and enabling the axillary bud ends of the cuttings to smoothly pass through the straight seedling row groove 33.

[0061] In this embodiment, the seedling pressing device 4 is arranged above the straight seedling row groove 33. The seedling pressing device 4 has a seedling pressing drive assembly to move downward at the same frequency as the seedling placing (the cuttings pass through the straight seedling row groove 33) to press the cuttings into the soil.

[0062] Since the whole device continues to move forward after the cuttings fall into and are inserted into the soil, therefore, the specific installation position of the seedling pressing device 4 is: with reference to the traveling direction of the traveling mechanism 5, it is arranged directly above the downstream of the alignment mechanism 32.

[0063] Specifically, the seedling pressing device 4 needs to perform a telescopic movement in coordination with the rotation frequency of the sorting wheel 21 to sequentially press down on multiple cuttings located in the straight seedling row groove 33.

[0064] This embodiment also provides an embodiment of the seedling pressing device 4, as Figure 4 shown:

[0065] The seedling pressing device 4 includes a lower pressing rod 41, a limit seat 42 and a driving mechanism; the limit seat 42 is provided with a through hole in the vertical direction, and the lower pressing rod 41 passes through the through hole, so that the lower pressing rod 41 is restricted to move vertically under the action of the driving mechanism only in a telescopic manner.

[0066] Specifically, the driving mechanism includes a pulley assembly, a connecting rod 45 and a seedling pressing driving assembly; the pulley assembly is arranged along the telescopic direction of the lower pressing rod 41, and the seedling pressing driving assembly drives the driving wheel 43 of the pulley assembly to rotate; the driven wheel 44 of the pulley assembly is provided with a coupling shaft at a position perpendicular to its own non-axis to form an eccentric wheel, and the two ends of the connecting rod 45 are respectively hinged to the coupling shaft and the end of the lower pressing rod 41.

[0067] Through the rotation of the driven wheel 44, the lower pressing rod 41 is driven to move vertically in a telescopic manner through the connecting rod 45.

[0068] In this embodiment, the traveling mechanism 5 has a traveling driving assembly 52; and the sorting driving assembly, the seedling pressing driving assembly and the traveling driving assembly 52 are driven synchronously; so that the rotation frequency of the sorting wheel 21, the pressing frequency of the seedling pressing device 4 and the moving distance of the traveling mechanism 5 are synchronized; so that during the entire cutting process, the traveling mechanism 5 does not need to stop and wait for the pressing action to be completed before moving forward, and can maintain normal movement to improve the cutting efficiency.

[0069] This embodiment also provides an embodiment of the traveling mechanism 5, such as Figure 1 and Figure 2 shown, the structure is as follows:

[0070] The traveling mechanism 5 includes a chassis (not marked), sprocket assemblies 51 arranged on both sides of the chassis, and a traveling driving assembly 52 for driving the sprocket assemblies 51 to rotate; a bracket (not marked) is provided on the chassis, and the seedling feeding chute 1, the sorting and seedling feeding device 2, the seedling placing device 3 and the seedling pressing device 4 are arranged on the bracket. The chassis is provided with a through hole at the position of the vertical space where the alignment mechanism 32 is located, so that the cuttings can pass through the chassis and be inserted into the soil.

[0071] Specifically, as Figure 7 shown, the end of the seedling feeding chute 1 (auxiliary blanking pipe 15), the sorting wheel 21 and the seedling placing channel 31 are arranged in the first housing 24 to play a protective role and are fixed on the bracket through the first housing 24; the entire seedling pressing device 4 is arranged in the second housing 46 to play a protective role and is fixed on the bracket through the second housing 46.

[0072] As Figure 5As shown in the figure, the traveling drive assembly 52 includes a third rotating shaft 53 and a second drive motor 54; the third rotating shaft 53 is used to connect the sprockets located on both sides of the chassis, and the sprockets on the same side are connected by chain drive; a third gear 45 is provided on the third rotating shaft 53, and a fourth gear 56 is provided on the output shaft of the second drive motor 54, and the third gear 45 and the fourth gear 56 are meshed; the second drive motor 54 is arranged on the chassis.

[0073] In this embodiment, the second drive motor 54 is vertically arranged, and the third gear 45 and the fourth gear 56 are bevel gears, which are a bevel gear set and adopt bevel gear transmission.

[0074] Furthermore, as Figure 6 shown, the traveling mechanism 5 further includes a handrail 58. The whole device is arranged inside a housing 57. The feed inlet 12 of the seedling feeding chute 1 is located outside the housing 57 to facilitate the feeding of cuttings. The handrail 58 is arranged on the side wall of the housing 57; it is used to adjust the traveling direction of the whole device and can move the whole device by manual pushing when necessary to improve the application range of the whole device.

[0075] In this embodiment, in order to improve the cutting efficiency, the following embodiments are also provided:

[0076] The seedling feeding chute 1 is provided with multiple groups, and each group of the seedling feeding chute 1 is respectively provided with a group of sorting and seedling feeding devices 2, a group of seedling placing devices 3 and a group of seedling pressing devices 4.

[0077] The sorting drive assembly and the seedling pressing drive assembly can be independent structures, respectively driving the sorting wheel 21 and the driving wheel 43 and maintaining synchronization.

[0078] Or the sorting drive assembly and the seedling pressing drive assembly are an integral structure, simultaneously driving the sorting wheel 21 and the driving wheel 43.

[0079] In order to simplify the structure and facilitate control, this embodiment selects the sorting drive assembly and the seedling pressing drive assembly as an integral structure; as Figure 2 and Figure 3 shown, the structure is as follows:

[0080] The sorting drive assembly includes a first rotating shaft 221 and a driven gear a 222 disposed at the middle position of the first rotating shaft 221, and a plurality of sorting wheels 21 are fixed on the same first rotating shaft 221; the seedling pressing drive assembly includes a second rotating shaft 223 and a driven gear b 224 disposed at the middle position of the second rotating shaft 223, and the driving wheels 43 of a plurality of pulley assemblies are disposed on the same second rotating shaft 223; the driven gear a 222 and the driven gear b 224 are meshed, and a driving gear 226 is provided on the output shaft of the first driving motor 225, and the driving gear 226 is meshed with the driven gear a 222 or the driven gear b 224, so that the first rotating shaft 221 and the second rotating shaft 223 are driven by the same first driving motor 225 to rotate synchronously.
