Description

Technical Field

[0001] This invention relates to the field of nut harvesting and threshing machines, specifically an adaptive impact-adjustable nut harvesting and threshing machine based on mid-to-high altitude harvesting. Background Technology

[0002] Existing nut harvesters typically use gasoline or gas as their power source to vibrate or beat tree branches. Gasoline-powered harvesters generally use a gasoline engine to provide energy, which is then transmitted to the harvesting components via a transmission system, driving them to vibrate or beat. Gas-powered harvesters, on the other hand, rely on compressed air from an air compressor to drive components such as the vibration mechanism to vibrate and beat the branches. These power methods have, to some extent, replaced manual labor and improved harvesting efficiency, and have been widely used in nut-growing areas.

[0003] However, current nut harvesters powered by gasoline or gas have gradually revealed many drawbacks in practical applications. Regarding stability, due to an inadequate design of the transmission structure between the power source and the harvesting components, the equipment is prone to shaking during operation, especially when harvesting thicker or more difficult-to-reach branches. The support structure struggles to remain stably fixed at the target position, affecting harvesting accuracy and effectiveness.

[0004] In terms of motion transmission, energy loss is significant during the transmission of power to the drilling components via the transmission system, resulting in insufficient accuracy and timeliness of motion transmission. For example, after long-term operation, the mechanical transmission components of gasoline-powered drilling machines often experience increased transmission clearance, leading to sluggish action response of the drilling components; in the air transmission process of gas-powered drilling machines, air pressure loss affects the vibration frequency and force stability of the excitation mechanism, thereby affecting the efficiency of motion transmission.

[0005] The problems are even more pronounced in terms of component wear and load bearing. When the vibrating or striking components of the tapping machine are in operation, the mechanical transmission components of gasoline-powered tapping machines, such as bearings and gears, wear out faster under long-term power transmission and load. Components of gas-powered tapping machines, such as the excitation mechanism and clamps, repeatedly collide with branches during vibration, making them not only prone to wear but also susceptible to damage due to uneven stress. Furthermore, when these components bear the loads during the tapping process, their design is insufficient to adapt to load changes, making them prone to overload and further exacerbating component damage.

[0006] More importantly, when the branches hooked on the nut-harvesting machine are too thick or the load is too heavy, a series of serious problems arise. In this situation, the drive components need to overcome greater resistance to move the nut-harvesting components, causing the driving reaction force to exceed the equipment's design range. Under these circumstances, the reciprocating speed of the nut-harvesting components will decrease significantly, the amplitude will also decrease drastically, and the harvesting force will weaken, failing to effectively shake the nuts off the branches and severely impacting harvesting efficiency. Even more seriously, a "jamming" phenomenon may occur, where the nut-harvesting components cannot reciprocate normally, forcing the equipment to stop working. This not only delays the harvesting progress but also causes irreversible damage to core components such as the drive motor and transmission gears. Simultaneously, under excessive load, the friction between the bearing rings and the track will increase dramatically, accelerating wear on both, shortening the lifespan of components, increasing maintenance costs and failure rates, and causing significant economic losses to nut growers. These problems have become bottlenecks restricting the further development and application of nut-harvesting machines and urgently need to be addressed.

[0007] Therefore, this invention proposes an adaptive impact-adjustable nut harvester based on mid-to-high altitude harvesting to solve the above problems. Summary of the Invention

[0008] In view of this, the technical problem to be solved by the present invention is to propose an adaptive impact-adjustable nut harvester based on mid-to-high altitude harvesting, so as to solve the problems existing in the prior art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an adaptive impact-adjustable nut harvester based on mid-to-high altitude harvesting, comprising: an instrument shell, and further comprising: a first component inside the instrument shell;

[0010] The first component includes a drive shaft that passes through it, and a double-groove rocker bearing is fixedly connected to the top of the drive shaft. Grooves A are symmetrically arranged around the ball of the double-groove rocker bearing.

[0011] The upper and lower ends of the double-groove rocking bearing are fixedly connected with auxiliary bearings, which are fitted into auxiliary slots inside the instrument housing.

[0012] The double-groove rocker bearing is fitted with a rocker element, and the inner ring wall of the rocker element is symmetrically provided with grooves B. Grooves B and groove A together restrict the sliding of the balls.

[0013] A guide cylinder is fitted into the auxiliary slot at the top of the instrument housing. A transmission rod is slidably connected inside the guide cylinder. A column is fixedly connected to the bottom end of the transmission rod. A vertical through slot is provided on the column.

[0014] Preferably, a second component is also included above the transmission rod;

[0015] The second component includes a module cylinder threadedly connected to the transmission rod. The module cylinder is divided into two chambers: the upper chamber is the working area, and the lower chamber has a threaded groove for installation.

[0016] The working area of ​​the module cylinder is symmetrically and fixedly connected with track bars. Auxiliary springs are fixedly connected to both the upper and lower ends of the track bars. An upper load block is slidably connected to the working chamber of the module cylinder. A strain gauge is fixedly connected to the bottom inner cavity of the upper load block.

[0017] Preferably, a lower load block is slidably connected to the working chamber of the module cylinder, a movable column is fixedly connected to the upper surface of the lower load block, a through hole A is opened at the bottom of the lower load block, and a through hole B is opened at the top of the lower load block.

[0018] The upper load block is located above the lower load block, and both the upper and lower load blocks are provided with sliding grooves that are compatible with the track bar. The sliding grooves are fixedly connected to the auxiliary spring.

[0019] Preferably, a rotating shaft is fixedly connected to the inner cavity of the lower load block, and a sealing plate is fixedly connected to the bottom end of the rotating shaft. The sealing plate is in close contact with the bottom surface of the inner cavity of the lower load block, and a sealing ring is sleeved on the outer circumference of the sealing plate.

[0020] The sealing sheet has through holes C spaced at equal intervals;

[0021] The top of the module cylinder is provided with a stabilizing groove, and the top of the module cylinder is connected to a mining head by means of the stabilizing groove and the threaded groove on the upper load block.

[0022] Preferably, the outer end rod of the swing member is slidably adapted to the vertical through groove.

[0023] Preferably, the module cylinder is divided into two chambers: the upper part is the working area, and the bottom inner cavity of the module cylinder has a threaded groove for installation; the working area contains a medium.

[0024] Preferably, the through hole A and the through hole B are aligned vertically.

[0025] Preferably, the bottom of the tapping head consists of two rings and a threaded post.

[0026] Compared with existing technologies, this invention provides an adaptive impact-adjustable nut harvester based on mid-to-high altitude harvesting, which has the following beneficial effects:

[0027] 1. The design of the first component in this invention provides the following advantages:

[0028] In terms of support and motion transmission, the rocker bearing, which is composed of a double-groove rocker bearing component and a rocker component, provides a stable and reliable support foundation for the mining device through precise cooperation with groove A, groove B and the ball, ensuring that it can achieve efficient rocker motion. At the same time, the bearing system has flexible motion adjustment capability, allowing the mining device to complete multi-degree-of-freedom rocker operation within a preset angle range. This feature not only ensures the high efficiency of impact energy transmission and minimizes energy loss, but also allows for precise control of the motion trajectory of the mining device, meeting the operational accuracy requirements under complex working conditions.

[0029] In terms of dynamic load bearing performance, this rocker bearing innovatively adopts an asymmetric raceway design with grooves A and B, combined with a high-rigidity cage structure, forming a powerful load-bearing system. This special design enables the bearing to maintain a stable operating state under the continuous action of high-frequency impact loads from the mining equipment, effectively resisting the adverse effects of vibration and impact. At the same time, its excellent structural characteristics give it comprehensive load-bearing capacity, capable of simultaneously handling the combined loads formed by radial loads, axial loads, and overturning moments, providing a solid guarantee for the long-term stable operation of the mining equipment.

[0030] 2. The present invention, through the design of dual through grooves A and B, can bring the following advantages:

[0031] Solving the problem of traditional bearing jamming and improving smooth operation: Distributing contact stress and reducing local jamming; When traditional single-slot bearings are subjected to radial or axial loads, the stress is concentrated in a single contact area. If there are small impurities, such as dust, fruit tree debris, or minor deformation of parts, jamming is likely to occur; The dual-slot design distributes the load through two independent slots, the contact points are more evenly distributed, the stress level of a single slot is reduced, and the impact of impurities or deformation on the overall movement is dispersed, greatly reducing the interruption of operation caused by local jamming;

[0032] Two-way guidance to compensate for installation errors: The two channels can form a mutually cooperating guide structure. Even if there are slight coaxiality deviations or angular errors during equipment installation, the two channels can adaptively adjust the force direction through their respective rolling elements, such as balls or rollers, avoiding the risk of "jamming" caused by misalignment in traditional single channels, and ensuring smoother reciprocating motion of vibrating components.

[0033] Enhanced structural stability and adaptability to complex working conditions: Improved anti-overturning capacity and reduced vibration deviation; During nut harvesting, the reaction force of branches may cause lateral torque to the vibrating components, especially when the branches are uneven in thickness and the force is unstable; Traditional single-slot bearings have weak resistance to lateral forces and are prone to shaft tilting, resulting in vibration trajectory deviation. The double-slot bearing, through its symmetrically distributed slot structure, forms a more stable support system, which can effectively resist lateral torque, reduce the deviation of the vibrating components, ensure the stability of vibration frequency and amplitude, and improve harvesting effect.

[0034] Adapting to the synergistic requirements of heavy loads and high-frequency vibrations: When handling thick branches and heavy loads, the tapping machine needs to meet the requirements of high load bearing and high-frequency reciprocating motion at the same time; the dual-slot design increases the number of contact points, that is, the number of contact pairs between the balls and the grooves, which not only improves the rigidity of the overall structure to withstand heavy loads, but also reduces energy loss under high-frequency vibration through the independent motion characteristics of the dual slots, ensuring more efficient power transmission and avoiding the performance degradation of traditional bearings under heavy load and high-frequency conditions.

[0035] 3. This invention, through the design of the second component, serves as a protective device to prevent overloading of the harvester. Addressing issues such as excessive reaction force, hindered movement, and accelerated component wear caused by excessively thick fruit branches and heavy loads, it offers the following benefits:

[0036] Preventing forced operation under overload conditions: When the fruit branches are too thick and the load exceeds the design range, the second component suspends the working process after self-starting protection, avoiding the core components such as the double-groove rocker bearing and the rocker component from continuously bearing abnormal loads under the excessive reaction force; the above design directly prevents the deterioration process from "reduced reciprocating speed and reduced amplitude" to "jamming", and prevents severe wear caused by forced friction between the double-groove rocker bearing and the rocker component, such as local scratches, metal fatigue cracks, and deformation or breakage of components such as the transmission rod due to overload;

[0037] To ensure stable motion transmission, maintain mining efficiency, and avoid performance degradation due to overload: When not overloaded, the second component does not interfere with normal operation, ensuring that the conversion efficiency from circular motion to linear motion is not affected; when overload occurs, a pause mechanism prevents the equipment from operating in a "low-efficiency mode," i.e., with reduced speed and amplitude, thus reducing ineffective operation time; once the load returns to normal, such as when replacing branches or adjusting hook positions, the equipment can be quickly restarted and restored to its design performance, ensuring overall mining efficiency;

[0038] Stable drive system operating conditions: Excessive reaction force during overload will cause the drive system to bear additional torque, which will lead to premature aging of drive components in the long run; the second component cuts off the reaction force of overload on the drive system, avoids the drive system from operating under abnormal torque, maintains its output stability, and indirectly ensures the consistency of motion transmission.

[0063] The top of the transmission rod 209 is provided with a threaded wire, which is used to fit and install it with the threaded groove in the bottom cavity of the module cylinder 301.

[0064] The outer end rod of the swing member 205 is slidably adapted to the vertical through groove 211.

[0065] A further embodiment: Please refer to Figures 6 to 10As shown:

[0066] The second component 3 includes a module cylinder 301 threadedly connected to the transmission rod 209. The module cylinder 301 is divided into two chambers: the upper part is the working area, and the lower part has a threaded groove for installation. Track bars 302 are symmetrically and fixedly connected to the working area of ​​the module cylinder 301. Auxiliary springs 303 are fixedly connected to the upper and lower ends of the track bars 302. An upper load block 304 is slidably connected to the working chamber of the module cylinder 301. A strain gauge 305 is fixedly connected to the bottom of the upper load block 304.

There is a through hole B309; the upper load block 304 is located above the lower load block 306, and both the upper load block 304 and the lower load block 306 are provided with sliding grooves that are compatible with the track bar 302. The sliding grooves are fixedly connected to the auxiliary spring 303. A rotating shaft 310 is fixedly connected in the inner cavity of the lower load block 306.

Through holes C312 are provided at equal intervals on the sealing plate 311. A stabilizing groove 313 is provided on the top of the module cylinder 301. The top of the module cylinder 301 is connected to the tapping head 314 through the stabilizing groove 313 and the threaded groove provided on the upper load block 304.

[0067] in:

[0068] The second component 3 is used to prevent overload operation during mining operations.

[0069] The module cylinder 301 is divided into two chambers. The upper part is the working area, and the bottom inner cavity of the module cylinder 301 has a threaded groove, which is the installation area. The working area contains a medium, which can be an inert gas or a solution, etc. Here, it is set to an aqueous solution.

[0070] The track bar 302 cooperates with the auxiliary spring 303 to ensure stable movement of the upper load block 304 and the lower load block 306.

[0071] The upper load block 304 has a threaded groove adapted to the threaded installation of the head 314.

[0072] The strain gauge 305 is connected to the main controller of the device. When the value fed back by the strain gauge 305 is greater than the load value that the device can withstand, the main controller can control the rotating shaft 310 to rotate and control the drive shaft 201 to stop working.

[0073] The bottom of the upper load block 304 is well sealed with the moving column 307.

[0074] Through hole A308 and through hole B309 are vertically aligned.

[0075] In the initial state, through hole C312 is not overlapping with through holes A308 and B309 in the vertical direction.

[0076] The installation of the head 314 is a triple installation. The bottom consists of two rings and a threaded post, which can be inserted and fitted into the upper end of the module cylinder 301. Its threaded post can be threadedly fixed to the upper load block 304.

[0077] It should be noted that this design, by screwing the module cylinder 301 onto the transfer rod 209 and the modular design of the second component 3, can effectively adapt to the installation of different models of mining heads 314, thereby increasing the mining working range.

[0078] The working principle of all the content in the above embodiments is as follows:

[0079] The following is the working process of the first component 2:

[0080] When in use, the harvester hangs the harvesting hook on the harvesting head 314 of the device on the fruit branch to be harvested, and then starts the drive shaft 201. The drive shaft 201 will drive the double groove rocking bearing 202 to rotate. As the double groove rocking bearing 202 rotates, with the assistance of the groove A203 on the double groove rocking bearing 202, the groove B206 of the rocking component 205, and the ball 207, the rocking component 205 will swing. During the above process, the auxiliary bearings 204 sleeved at both ends of the double groove rocking bearing 202 will provide stable support for the double groove rocking bearing 202 during the working process.

[0081] Furthermore, as the swinging member 205 swings, the outer end of the swinging member 205 will cause the column member 210 to move up and down with the transmission rod 209 on it, under the premise of actuating the vertical through groove 211. At this time, the guide cylinder 208 provides a state maintenance function for the stable guidance of the movement of the transmission rod 209.

[0082] Under the premise of the reciprocating motion of the aforementioned transmission rod 209, the transmission rod 209, which is indirectly connected to the harvesting head 314 through the second component 3, will use the harvesting hook to effectively vibrate and harvest the fruit branches.

[0083] Please refer to the above work process. Figures 1 to 5 .

[0084] The following is the working process of the second component 3:

[0085] Furthermore, during the tapping process, if the tapping hook is hung on a thicker branch, there may be an overload situation. In this case, during the vibration, the strain gauge 305 in the bottom cavity of the upper load block 304 will show an increased value under the pressure of the moving column 307. Since the strain gauge 305 is connected to the main controller of the device, when the value fed back by the strain gauge 305 exceeds the load value that the device can withstand during tapping, the main controller can control the rotating shaft 310 to rotate and control the drive shaft 201 to stop working. That is, at this time, the through hole A308, which was originally sealed by the sealing plate 311, will be closed by the rotation of the rotating shaft 310 and the through hole C3. With the overlap of through holes C312 and A308, the aqueous solution in the original working area of ​​module cylinder 301 will move into the lower load block 306 and move upward through the through hole B309 at the top of the lower load block 306, thereby relieving the overload force when stuck and providing effective buffering. During this process, the track bar 302 and auxiliary spring 303 provide stable services for the movement of the upper load block 304 and the lower load block 306. In summary, the design of the second component 3 can effectively prevent the harvester from overloading, especially for problems such as excessive reaction force, obstructed movement, and accelerated wear of components caused by excessively thick fruit branches and excessive load.

[0086] Please refer to the above work process. Figures 6 to 10 .
