Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a device for removing high-position buds from sugarcane. Background Technology

[0002] In sugarcane cultivation, to improve lodging resistance, a method can be used to remove the high-ranking buds at the top of the stalk while retaining the low-ranking buds at the base. The principle behind this method is that the roots of new plants sprouting from low-ranking buds are closer to the soil surface, resulting in denser root systems and faster nutrient absorption. The stalk base is also thicker and has higher mechanical strength. Simultaneously, the plant height is reduced, and the center of gravity shifts downward, which, according to mechanical principles, reduces the lodging moment. Furthermore, it reduces pests and diseases, promotes concentrated nutrient supply to the low-ranking buds, and enhances the lodging resistance of the sugarcane plant population. However, this method is not yet widely adopted. On the one hand, growers do not understand why healthy high-ranking buds should be removed, finding it a waste. On the other hand, it requires manual labor, which has many drawbacks, such as high labor costs and low efficiency, making it difficult to meet the needs of large-scale sugarcane cultivation. Moreover, uneven force and height control during manual operation can easily damage low-ranking buds or incompletely remove high-ranking buds, affecting subsequent growth and lodging resistance. Therefore, there is an urgent need to design a device for removing high-level buds from sugarcane to replace manual operation and improve work efficiency and quality. Utility Model Content

[0003] This invention proposes a device for removing high-position buds from sugarcane, which solves the problem of high workload and low efficiency caused by the need for manual removal of high-position buds in existing technologies.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An apparatus for removing high-level buds from sugarcane, comprising:

[0006] The frame has a suspension bracket in the middle of its top surface for detachable connection to the tractor's rear suspension;

[0007] A transmission mechanism includes a transmission box for detachably connecting the tractor's power take-off shaft and a transmission shaft that is driven through the transmission box; the transmission box is fixedly installed in the middle of the top surface of the frame and located within the suspension frame; the transmission shaft is rotatably installed above the frame and parallel to the length direction of the frame; a first connecting seat and a second connecting seat are rotatably installed on the left and right sides of the frame, respectively, and the first connecting seat is driven through a transmission wheel assembly to one end of the transmission shaft;

[0008] The actuator includes a rotating shaft and multiple blade assemblies. The left and right ends of the rotating shaft are detachably connected to a first connecting seat and a second connecting seat, respectively. Several connecting ears for mounting the blade assemblies are fixedly installed in the middle of the rotating shaft, with two adjacent connecting ears forming a group. Each blade assembly includes two L-shaped blades arranged back-to-back. The upper parts of the two L-shaped blades are movably sleeved on a mounting shaft. Two connecting ears of the same group are movably passed through both ends of the mounting shaft and are threaded with locking nuts. The corners of the L-shaped blades are transitioned by arcs, and the included angle between the extended lines of the two ends is 90°. The thickness of the L-shaped blades is 0.4-0.6 cm.

[0009] Furthermore, the transmission wheel assembly is a belt pulley assembly or a sprocket assembly.

[0010] Furthermore, both ends of the rotating shaft are detachably connected to the first connecting seat and the second connecting seat by a number of locking bolts, and the locking bolts are threaded with fastening nuts.

[0011] Furthermore, the rotating shaft includes a first segment, a second segment, and a third segment. One end of the first segment is detachably connected to a first connecting seat, and the other end is detachably connected to one end of the second segment. The other end of the second segment is detachably connected to one end of the third segment, and the other end of the third segment is detachably connected to a second connecting seat. A plurality of connecting ears are provided on the outer peripheral surfaces of the first segment, the second segment, and the third segment.

[0012] Furthermore, flanges are provided at both ends of the first segment, both ends of the second segment, both ends of the third segment, the connecting surface of the first connecting seat, and the connecting surface of the second connecting seat. Adjacent flanges are detachably connected by locking bolts and fastening nuts.

[0013] Furthermore, the second segment is provided with connectors at both ends, and the first segment and the third segment are respectively provided with connecting slots for the connectors to be inserted.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] 1. The frame and transmission mechanism of this utility model are conventional structures, equivalent to the main structure of a large rotary tiller. The actuator is improved by adding a rotating shaft and multiple blade assemblies. Before operation, the height is adjusted via the tractor suspension. During operation, the blade assemblies rotate at high speed with the rotating shaft, removing the high-level buds of the sugarcane while avoiding the low-level buds. This achieves the function of removing high-level buds while retaining low-level buds, making it suitable for removing high-level buds from sugarcane and avoiding the problems of high workload and low efficiency caused by manual operation.

[0016] 2. The swivel blade assembly of this utility model is equipped with two L-shaped blades. The L-shaped blades are different from the blades of conventional swivel blades. Conventional blades are generally used for cutting and crushing operations, so the blades are thinner, the included angle between the extension lines of the upper and lower ends of the blade is an obtuse angle, and the blades are not as curved as they are. However, the L-shaped blades of this utility model are not used for cutting or crushing operations, but for knocking off the high-level buds of sugarcane. Therefore, the blades are thicker and blunter, the included angle between the extension lines of the two ends is 90°, making the blades more curved, the striking area is larger, and the working efficiency is higher.

[0017] 3. This utility model only requires a blade assembly in the middle of the rotating shaft, and the number and spacing of the blade assemblies can be adjusted according to the sugarcane planting row spacing to meet different usage needs. Since it is not necessary to install blade assemblies on the entire rotating shaft, the number of blade assemblies can be effectively reduced, thereby lowering manufacturing and maintenance costs. This structural design is significantly different from existing technologies that install blade assemblies on the entire rotating shaft to achieve all-area mowing and shredding operations.

[0018] 4. This utility model is applicable to large tractor drives and can be used for operations in large-area sugarcane fields. The rotating shaft includes detachable first, second, and third sections, each of which can be fitted with a blade assembly as needed. Therefore, the three sections can be disassembled and used separately. These disassembled sections can be installed on a rotary tiller driven by a small hand-held tractor, enabling the removal of high-position buds in mountainous sugarcane fields inaccessible to large machinery, demonstrating good practicality.

[0019] 5. This utility model has several connecting ears installed on the first, second and third sections of the rotating shaft. Conventional blade structures can be installed on the connecting ears to achieve conventional grass cutting and shredding operations.

[0020] 6. Because the rotating shaft of this utility model adopts a segmented connection structure, when a segment is damaged, only that segment needs to be replaced, without replacing the entire rotating shaft, which can further reduce equipment maintenance costs. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1 As shown, a device for removing high-position buds from sugarcane includes a frame 1, a transmission mechanism, and an actuator. The frame 1 has a suspension bracket 2 located at the center of its top surface for detachable connection to the rear suspension of a tractor.

[0029] The transmission mechanism includes a transmission housing 3 for detachably connecting the tractor's power take-off shaft and a drive shaft 4 that is drively connected to the transmission housing 3. The transmission housing 3 is fixedly mounted on the center of the top surface of the frame 1 and located within the suspension frame 2. The drive shaft 4 is rotatably mounted above the frame 1 and is parallel to the length direction of the frame 1.

[0030] A first connecting seat 6 and a second connecting seat 7 are rotatably mounted on the left and right sides of the frame 1, respectively. The first connecting seat 6 is connected to one end of the drive shaft 4 via a drive wheel assembly 5. The drive wheel assembly 5 is either a pulley assembly or a sprocket assembly. In this embodiment, the drive wheel assembly 5 is a pulley assembly, which includes an upper pulley, a lower pulley, and a drive belt. The upper pulley is connected to the drive shaft 4, and the lower pulley is connected to the drive rod of the first connecting seat 6. The drive rod of the first connecting seat 6 is rotatably connected to the frame 1. The drive belt is connected to the upper pulley and the lower pulley, and the size of the upper pulley is larger than that of the lower pulley.

[0031] The frame 1 and transmission mechanism of this utility model are conventional structures, equivalent to the main structure of a large rotary tiller, suitable for use by large tractors and applicable to large-area sugarcane fields. Based on this, the actuator is improved by adding a rotating shaft 8 and multiple blade assemblies, as detailed below.

[0032] The actuator includes a rotating shaft 8 and multiple blade assemblies. The left and right ends of the rotating shaft 8 are detachably connected to the first connecting seat 6 and the second connecting seat 7, respectively. Specifically, the two ends of the rotating shaft 8 are detachably connected to the first connecting seat 6 and the second connecting seat 7 by several locking bolts, and the locking bolts are threaded with fastening nuts.

[0033] Several connecting ears 12 for mounting the blade assembly are fixedly installed in the middle of the rotating shaft 8, with two adjacent connecting ears 12 forming a group. The blade assembly includes two L-shaped blades 13 arranged back-to-back. The upper parts of the two L-shaped blades 13 are movably sleeved on a mounting shaft. Two connecting ears 12 of the same group are movably passed through both ends of the mounting shaft and are threaded with locking nuts. The corners of the L-shaped blades 13 are rounded, and the included angle between the extended lines of the two ends is 90°. The thickness of the L-shaped blades 13 is 0.4-0.6 cm. In this embodiment, the thickness of the L-shaped blades 13 is 0.5 cm.

[0034] The L-shaped blade 13 differs from the blades of conventional shovels. Conventional blades are generally used for cutting and crushing, so they are thinner, the angle between the extension lines of the upper and lower ends of the blade is obtuse, and the blade is not as curved overall. However, the L-shaped blade 13 of this invention is not used for cutting or crushing, but for removing the high-level buds of sugarcane. Therefore, the blade is thicker and blunter, the angle between the extension lines of the two ends is 90°, making the blade more curved overall, with a larger striking area and higher working efficiency.

[0035] Before the actuator starts working, the height is adjusted by the tractor suspension. When the actuator starts working, the L-shaped blade 13 of the slinger assembly rotates at high speed with the rotating shaft 8 to knock off the high-position buds on the upper part of the sugarcane and avoid the low-position buds on the lower part, thereby achieving the function of removing high-position buds and retaining low-position buds. It is suitable for removing high-position buds of sugarcane and avoids the problems of large workload and low efficiency caused by manual operation.

[0036] This invention only requires a blade assembly in the middle of the rotating shaft 8, and the number and spacing of the blade assemblies can be adjusted according to the sugarcane planting row spacing to meet different usage needs. Since it is not necessary to install blade assemblies on the entire rotating shaft 8, the number of blade assemblies can be effectively reduced, thereby lowering manufacturing and maintenance costs. This structural design is significantly different from existing technologies that install blade assemblies on the entire rotating shaft 8 to achieve all-field mowing and shredding operations.

[0037] Example 2

[0038] like Figure 2-4As shown, based on Embodiment 1, the rotating shaft 8 in this embodiment includes a first segment 9, a second segment 10, and a third segment 11. One end of the first segment 9 is detachably connected to the first connecting seat 6, and the other end is detachably connected to one end of the second segment 10. The other end of the second segment 10 is detachably connected to one end of the third segment 11, and the other end of the third segment 11 is detachably connected to the second connecting seat 7. Specifically, flanges 14 are provided at both ends of the first segment 9, both ends of the second segment 10, both ends of the third segment 11, the connecting surface of the first connecting seat 6, and the connecting surface of the second connecting seat 7. Adjacent flanges 14 are detachably connected by locking bolts 15 and fastening nuts 16, providing good ease of assembly and disassembly. Connecting heads 17 are also provided at both ends of the second segment 10. Connecting grooves for inserting the connecting heads 17 are correspondingly provided in the first segment 9 and the third segment 11. By providing connecting heads 17, the mechanical performance and stability of the connection are improved. Several connecting ears 12 are provided on the outer peripheral surfaces of the first segment 9, the second segment 10, and the third segment 11, so that the knife-slinging assembly can be installed on the three segments.

[0039] The rotating shaft 8 of this invention includes detachable first section 9, second section 10, and third section 11, each of which can be fitted with a blade assembly as needed. Therefore, the three sections can be disassembled and used separately. The disassembled sections can be installed on a rotary tiller driven by a small hand-held tractor, enabling the removal of high-position buds in sugarcane fields in mountainous areas inaccessible to large machinery, thus demonstrating good practicality.

[0040] Because the rotating shaft 8 of this utility model adopts a segmented connection structure, when a segment is damaged, only that segment needs to be replaced, without the need to replace the entire rotating shaft 8, which can further reduce equipment maintenance costs.

[0041] In addition, this utility model has several connecting ears 12 installed on the first segment 9, the second segment 10 and the third segment 11 of the rotating shaft 8. Conventional blade structures can be installed on the connecting ears 12 to realize conventional grass cutting and shredding operations, thus achieving multiple functions.

[0042] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
