Description

Technical Field

[0001] This utility model relates to a swing-type harvesting device, belonging to the field of agricultural harvesting machinery technology. Background Technology

[0002] Currently, the main methods used in existing harvesting devices for fruits such as pears, drupes, and berries include bent-axis circular motion, direct reciprocating motion, and eccentric vibration.

[0003] Chinese invention patent 2016105567008 discloses a handheld tree branch vibration fruit harvesting device. It uses a multi-stage transmission mechanism, including a drive mechanism, a transmission mechanism, a vibration mechanism, a manual clamping mechanism, a tree branch clamping head, and a ratchet locking mechanism. This results in indirect work, high energy consumption, and low harvesting efficiency. During harvesting, the tree branch clamping head is used to clamp the tree branch, and then the vibration mechanism converts the rotational motion of the accelerator into the linear reciprocating motion of the vibrating rod, which drives the tree branch clamping head to drag the tree branch back and forth to achieve harvesting. This harvesting method causes some damage to the trees. The overall structure of the device is complex and the manufacturing cost is high.

[0004] Chinese utility model patent 2017218586492 discloses a fruit picker that can swing left and right. Its motor is connected to the tail end of a hollow cylindrical tube. The motor drives a long rotating shaft, which in turn connects to a curved shaft. The curved shaft rotates and creates friction with a sleeve fixed with a hook, causing the sleeve to rotate. A spring force then returns the sleeve to its original position, achieving the purpose of swinging left and right to pick fruit. Because the rotating shaft runs through the entire hollow cylindrical tube and is quite long, the motor's energy consumption is relatively high. Furthermore, the method of using friction to rotate the sleeve and then using spring force to return it to its original position is also energy-intensive. Therefore, the overall energy consumption of this fruit picker is high. Secondly, when picking fruit by hand, the vibration is directly transmitted to the hand, which can cause numbness after a long time, resulting in a poor experience. Thirdly, the rear-mounted motor is insufficient for picking thicker branches. Finally, prolonged use can easily cause spring fatigue, leading to damage to the picking head.

[0005] Chinese utility model patent 2024214625801 discloses an eccentric branch shaking device, including a battery assembly, a handle control assembly, a connecting pipe assembly, a connecting shock-absorbing sleeve, a power unit, and a branch shaker. The power unit is connected to the connecting pipe assembly through the shock-absorbing sleeve, which overcomes the defect that vibration is directly transmitted to the hand when picking by hand, and does not damage the tree during picking; however, it relies solely on vibration to pick, and immature fruits are difficult to shake off the branches. Summary of the Invention

[0006] To address the above problems, the purpose of this utility model is to provide a swinging harvesting device that automatically shakes the fruit off branches by high-speed circular arc reciprocating swinging motion, thereby improving harvesting efficiency, reducing labor costs, minimizing operational safety hazards, protecting the fruit and fruit trees, and promoting the efficient, high-yield, and sustainable development of the fruit industry.

The reciprocating swing plate is a long strip plate, and a rotating shaft hole, a motor shaft hole, a guide hole, and one or more branch shaker fixing holes are respectively opened along the centerline of the length direction on the reciprocating swing plate; the rotating shaft hole is fixed to the rotating shaft; the motor shaft hole mates with the bearing on the cam; the guide hole mates with the guide shaft; and a branch shaker is fixed in one of the branch shaker fixing holes.

[0009] The branch shaker is a double-hook branch shaker with two hooks.

[0010] The shock-absorbing sleeve is a rubber sleeve with a through hole in the middle, and a shock-absorbing groove is opened inside the shock-absorbing sleeve.

[0015] The length of the circular tube in the connecting pipe assembly is 500mm to 2000mm;

[0016] A shock-absorbing handle assembly is fixed on the round tube of the connecting pipe assembly;

[0017] The shock-absorbing handle assembly includes: a clamping sleeve, a handle shock-absorbing sleeve, a fixing screw, and a handle.

[0018] The guide hole is an elongated hole or an arc-shaped hole.

[0019] The branch shaker fixing hole has two opposing straight edges.

[0020] The rear end of the connecting pipe assembly is connected to the handle control assembly, and the front end is connected to the power unit through a shock-absorbing sleeve. The handle control assembly is equipped with a speed control switch, and the output end of the speed control switch is connected to the motor through a transition wire passing through the connecting pipe assembly and the shock-absorbing sleeve.

[0021] The present invention has the following beneficial effects:

[0022] (1) By shaking the trunk or branches, the fruit falls off automatically, which greatly improves the efficiency of the operation.

[0023] (2) The eccentric branch shaking device directly vibrates and shakes the branches, replacing manual picking operations and greatly reducing labor intensity.

[0024] (3) Workers do not need to come into direct contact with tree branches, thus avoiding the injury caused by thorns and reducing safety hazards during operation.

[0025] (4) This utility model adopts a shock-absorbing handle and a shock-absorbing sleeve, which greatly reduces the vibration generated by the DC motor transmitted to the operator's hand, making the operator's operation safer and more comfortable.

[0026] (5) By vibrating and shaking the trunk or branches, workers are prevented from directly contacting the fruit with simple tools, thus avoiding damage to the fruit and protecting its integrity.

[0027] (6) This utility model adopts a double hook branch shaker (or other types of branch shakers). The branch shaker is made of plastic material (POM, PTFE). By vibrating and shaking the branches, the fruit falls off directly, which is convenient and reliable, and effectively protects the fruit and branches. By vibrating and shaking the trunk or branches, the fruit tree is not damaged or destroyed, and the yield reduction caused by traditional pruning operations in the following year is avoided.

[0028] (7) For different fruits and different ripening levels of the same type of fruit, the motor rotates at high speed, which drives the cam and bearing to rotate. Through the eccentric movement of the cam and bearing, the reciprocating swing plate is driven to swing in a reciprocating arc, so that the hook head swings in a reciprocating arc, achieving the picking effect. For different fruits and ripening levels, the swing frequency can be changed by adjusting the speed switch, and the swing amplitude can be changed by adjusting the hole of the reciprocating swing plate, so that the fruits can be picked efficiently over a large area. It is highly practical and has a wide range of applications.

[0029] (8) This utility model adopts a portable carrying method, which reduces the labor force of the operator, improves the work efficiency, and makes the application more flexible and convenient.

[0030] (9) This utility model uses a new energy ternary lithium battery, which is powered by pure electric drive. It has almost zero pollution and zero emissions, reducing the emission of gases such as carbon dioxide, and is more in line with the modern environmental protection concept of carbon peaking and carbon neutrality.

[0031] (10) The connecting pipe used in this utility model is flexible and easy to disassemble. Different lengths of connecting rods (500mm to 2000mm) can be used according to different fruit trees, making it more practical and with a wider range of applications. Attached Figure Description

The clamping sleeve 301 and the handle 304 are connected and fixed by the fixing screw 303, and the handle shock-absorbing sleeve 302 is pressed and fixed on the round tube 402.

[0067] The power unit 500 includes a DC motor 508 housed in the front cavity of the lower fixed base 511. The upper fixed base 507 clamps the DC motor 508 and connects it to the lower fixed base 511 via a hexagonal nut 524, a flat washer 525, a spring washer 526, and an internal hexagonal screw 527. A double shock-absorbing sleeve 510 is placed in the rear cavity of the lower fixed base 511. A round tube 402 passes through the double shock-absorbing sleeve 510 and is clamped to the lower fixed base 511 by a pressure seat 509 via screws, nuts, flat washers, and spring washers. Rotary... The shaft seat and guide shaft seat are provided with a reciprocating swing plate 520 at the front end of the power unit 500. The reciprocating swing plate 520 is a long strip plate. Along the center line of the length direction of the reciprocating swing plate 520, there are respectively a rotating shaft hole A, a motor shaft hole B, a guide hole C, a first swayer fixing hole D, and a second swayer fixing hole E. The guide hole C is an arc hole, and the swayer fixing hole has two opposite straight edges. Two bearings 512 are pressed into the rotating shaft seat, and a rotating shaft 516 is inserted into the bearings 512. The front end of the rotating shaft 516 is inserted into the rotating shaft hole A of the reciprocating swing plate, and is connected by a flat washer 513 and a spring washer 514. 14.

It is inserted into the corresponding first branch shaker fixing hole D or second branch shaker fixing hole E of the reciprocating swing plate and fixed with hexagonal screws 504, flat washers 502, and spring washers 503. The DC motor 508 rotates, driving the cam 518 and bearing 519 to rotate. Through the eccentric movement of the cam 518 and bearing 519, the reciprocating swing plate 520 is driven to perform reciprocating circular arc swings, thus causing the hooks of the branch shaker 501 to perform reciprocating circular arc swings, achieving the harvesting effect.

[0068] This invention uses a charger to charge the battery. After full charge, the operator carries the power supply unit (excluding the charger) on their back. The operator operates the unit via a handle control assembly and a shock-absorbing carrying handle assembly. The power supply unit continuously powers the motor, causing it to rotate. This rotation drives the cam and bearing to rotate, and the eccentric movement of the cam and bearing drives the reciprocating swing plate to swing in a reciprocating arc, thus causing the hook of the fruit shaker to swing in a reciprocating arc, achieving the harvesting effect. The swing frequency can be changed via a speed control switch, and the swing amplitude of the hook can be adjusted by changing the installation position of the fruit shaker in different fixing holes on the reciprocating swing plate. This allows for efficient and large-area harvesting of fruit, making it suitable for different fruits and different ripening levels of the same type. It is highly practical and has a wide range of applications.

[0069] This utility model uses a new energy ternary lithium battery for pure electric drive, resulting in almost zero pollution and zero emissions. It reduces emissions of gases such as carbon dioxide and is more in line with the modern environmental protection concept of carbon peaking and carbon neutrality.
