[0002] Coffee is one of the three major beverages in the world. Along with cocoa and tea, it is a major beverage popular in the world. It is loved by many people for its rich aroma, mellow taste, and refreshing effect.

[0003] High-quality coffee requires ripe fresh fruit. The main coffee producing areas in my country are located in mountainous areas, which are not suitable for large-scale machinery operations. Large-scale machinery is not easy to grade. Currently, most people use manual and small-scale machinery to pick coffee. Most of the existing small-scale coffee picking machines are roller-type, which are easy to pick coffee leaves together, and are not easy to grade and pick. The cost of later grading is high. Therefore, there is an urgent need for a small-scale coffee picking device that can be efficiently and easily carried and can grade coffee. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and beneficial effects of the present invention more clear, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0019] As shown in the figure, a pneumatic vibration coffee picking machine includes a housing 1, a quick connector 2, a pneumatic vibrator 3, a slider 4, a locking mechanism 5, a connecting rod 6, and a clamping head 7; the housing 1 is provided with a quick connector 2 at the rear end for connecting with the pipeline of the external air supply equipment to introduce high-pressure air to provide pneumatic power for the picking machine, making the connection more convenient. The quick connector 2 is connected to the piston telescopic pneumatic vibrator 3 installed in the housing 1 through a pipeline, and a shutoff valve 8 and a speed regulating valve 9 are provided on the connecting pipeline in sequence. The upper limit of the vibration frequency of the pneumatic vibrator 3 is 34-60Hz, the vibration force is 12-42N, and the air consumption is: 8-30L / min. The shutoff valve 8 adopts a two-position two-way valve to control the on-off of the air circuit to realize the start and shutoff of the pneumatic vibrator 3. The model of the speed regulating valve 9 is AS2211F-01-08S, which is used to control the gas flow in the air circuit to realize the speed adjustment of the pneumatic vibrator 3. The piston rod of the pneumatic vibrator 3 is hinged with a connecting piece 10 perpendicular to the movement direction of the piston rod. The connecting piece 10 is U-shaped, and one end is clamped on both sides of the piston rod and connected to the piston rod through a rotating shaft to form a hinge. A through hole matching the connecting rod 6 is set at the other end for connecting the connecting rod 6. The connecting piece 10 can also adopt a tubular structure, one end of which is hinged to the piston rod, and the other end is used to allow the left end of the connecting rod 6 to be inserted to form a sleeve connection. A slider 4 is slidably installed at the front end of the shell 1 and locked by a locking mechanism 5. A connecting rod 6 is hinged on the slider 4, and the rear end of the connecting rod 6 is inserted into the connecting piece 10. A clamping head 7 is provided at the front end of the connecting rod 6. The connecting piece 10, the connecting rod 6, and the clamping head 7 are located on the same straight line. When the pneumatic vibrator 3 is actuated, the piston rod of the pneumatic vibrator 3 reciprocates up and down, and the connecting rod 6 is driven by the connecting piece 10 to swing with its hinge point with the slider 4 as a fixed point, and the connecting rod 6 drives the clamping head 7 to swing. The clamping head 7 is Y-shaped, and its root is connected to the right end of the connecting rod 6. When working, the end of the clamping head 7 is clamped on the coffee branch, the on-off valve 8 is opened, and the pneumatic vibrator 3 is activated, and the clamping head 7 is driven to swing up and down through the connecting piece 10 and the connecting rod 6, thereby vibrating the coffee fruit down, helping the staff to complete the coffee fruit picking operation, and effectively improving the staff's efficiency in picking coffee fruit. At the same time, the distance between the hinge point of the connecting rod 6 and the slider 4 and the pneumatic vibrator 3 can be changed by sliding the slider 4 left and right, thereby changing the vibration amplitude of the clamping head 7 to meet the needs of picking fresh coffee fruits in different maturity conditions.

[0020] Furthermore, the shell 1 is in the shape of a gun, which is convenient for users to perform one-handed or two-handed operations, and includes a gun body portion 1-1, a grip portion 1-2, a magazine portion 1-3, and a barrel portion 1-4. The grip portion 1-2 and the magazine portion 1-3 are arranged on the side of the gun body portion 1-1. Preferably, non-slip guards are provided on both side surfaces of the grip portion 1-2, and ergonomic design is performed to facilitate users to hold the grip portion 1-2 tightly. The barrel portion 1-4 is arranged at the front end of the gun body portion 1-1, and the on-off valve 8 is installed in the grip portion 1-2. A trigger 11 is hinged in front of the grip portion 1-2 and is reset by a reset spring 12 arranged in the gun body portion 1-1. When the trigger 11 is pulled, the trigger 11 pushes the on-off valve 8 to open it. The pneumatic vibrator 3 is installed in the magazine portion 1-3, the connecting rod 6 is installed in the barrel portion 1-4, and the clamping head 7 extends forward from the front end of the barrel portion 1-4.

[0021] Further, the locking mechanism 5 includes a U-shaped sleeve handle 5-1, a top block 5-2, and a spring 5-3; the sleeve handle 5-1 is sleeved on the lower side of the barrel portion 1-4, and its upper end clamps the slider 4 from both sides and is fixedly connected to the slider 4 by screws. A mounting hole is provided at the bottom of the sleeve handle 5-1, and a top block 5-2, a spring 5-3, and a locking bolt are arranged in sequence from the inside to the outside of the mounting hole. A wavy locking block 5-4 used in conjunction with the top block 5-2 is provided on the lower side of the barrel portion 1-4, and the mounting hole passes through the sleeve handle 5-1. The locking bolt and the sleeve handle 5- 1 is screwed together with the thread and the lower end of the mounting hole is closed. The spring 5-3 is in a compressed state, driving the top block 5-2 to move upward and press against the locking block 5-4. Under normal conditions, the top block 5-2 presses against the trough of the locking block 5-4, clamps the sleeve handle 5-1, fixes the position of the sleeve handle 5-1, and thus fixes the position of the slider 4. When the sleeve handle 5-1 is pushed backward or forward with force, the top block 5-2 slides along the locking surface and overcomes the elasticity of the spring 5-3 to move into the mounting hole, then slides into another trough and extends out again to fix the position of the sleeve handle 5-1. The position of the slider 4 can be adjusted by pushing the sleeve handle 5-1 forward or pulling it backward, and the adjustment of the swing amplitude of the clamping rod is more convenient.

[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention; the dimensions of the drawings are independent of the specific objects, and the dimensions of the objects can be changed arbitrarily.
