Description

Technical Field

[0001] This utility model relates to the field of chili pepper picking technology, specifically to a chain conveyor chili pepper picking device. Background Technology

[0002] A chili pepper picking device is an agricultural machine used for the automated harvesting of mature chili peppers. It primarily addresses the problems of low efficiency and high cost associated with manual harvesting and is suitable for large-scale chili pepper cultivation bases. During chili pepper harvesting, a chili pepper picking device is needed to transport and process the peppers. To facilitate transport, the conveyor belt of the chili pepper picking device is usually equipped with claw-like structures to secure the peppers and prevent them from rolling off the conveyor during transport. However, the chili pepper stems remain on the peppers after harvesting. During transport, the stems can easily get stuck on the claw-like structures of the picking device, preventing the peppers from automatically falling off the conveyor after reaching the designated location. This necessitates manual removal of the peppers stuck on the picking device. Therefore, we propose a chain-conveyor chili pepper picking device. Utility Model Content

[0003] The purpose of this invention is to provide a chain-conveyed chili pepper picking device to solve the problem mentioned in the background art that chili pepper stems are easily stuck on the picking device during the conveying process.

[0004] To achieve the above objectives, this utility model provides a chain-conveyor chili pepper picking device, including a conveying assembly. The conveying assembly includes a support plate, and a conveyor belt is rotatably mounted on the upper side of the support plate. Multiple fixing rods are fixedly mounted on the upper side of the conveyor belt, and multiple fixing components are mounted on the upper side of the fixing rods. Each fixing component includes a pad, which is fixedly mounted on the upper side of the fixing rod. A spring tooth is rotatably mounted on one side of the pad, and a protrusion is fixedly mounted on the side of the spring tooth near the pad. A groove matching the protrusion is opened on the upper side of the pad, and a pressure spring is fixedly mounted between the spring tooth and the fixing rod.

[0005] The conveyor belt is used to move multiple fixed components and transport chili peppers. In the initial state, the spring teeth are pressed upward by the pressure spring, and the protrusion on one side of the spring teeth is pressed into the groove on the side of the pad, so that the spring teeth are flush with the pad.

[0006] As a further improvement to this technical solution, the two rotating shafts of the conveyor belt are respectively rotatably mounted on the upper and lower ends of the support plate, and toothed wheels are fixedly mounted on both ends of the two rotating shafts of the conveyor belt, with multiple toothed wheels mounted on the inner side of the support plate.

[0007] As a further improvement to this technical solution, synchronous belts are symmetrically fixedly arranged on the inner side of the conveyor belt, and multiple toothed pulleys are respectively arranged at both ends of the two synchronous belts, and the two synchronous belts are meshed with the corresponding toothed pulleys.

[0008] As a further improvement to this technical solution, a motor is fixedly installed on the upper side of the support plate. The motor is located on the outer side of the support plate, and the rotating shaft of the motor is fixedly connected to one end of the rotating shaft on the upper side of the support plate.

[0009] The motor drives multiple toothed wheels to rotate. When the motor is started, the multiple toothed wheels drive two synchronous belts to rotate. At the same time, the two synchronous belts drive the conveyor belt to rotate. The conveyor belt drives multiple fixed components to transport the chili peppers.

[0010] As a further improvement to this technical solution, a support component is provided on one side of the conveying component. The support component includes a fixed frame, and the upper side of the support plate is rotatably connected to the upper side of the fixed frame.

[0011] As a further improvement to this technical solution, hydraulic cylinders are symmetrically arranged between the fixed frame and the support plate. One end of the hydraulic cylinder is fixedly connected to the fixed frame, and the other end of the hydraulic cylinder is rotatably connected to the middle position of the support plate.

[0012] The hydraulic cylinder is used to push the support plate and drive it to rotate, so as to adjust the angle of the support plate.

[0013] As a further improvement to this technical solution, a feeding hopper is fixedly installed on the side of the fixed frame away from the conveying assembly, a part of the feeding hopper is located on the lower side of the support plate, and a stop bar corresponding to the spring tooth is fixedly installed on the upper side of the feeding hopper.

[0014] The feeding hopper is used to hold chili peppers. When the chili peppers are transported to the upper side of the feeding hopper, one end of the spring tooth gradually comes into contact with the stop bar. As the spring tooth continues to move downward, the stop bar presses the spring tooth down. After the spring tooth passes the stop bar, the pressure spring immediately bounces the spring tooth up, and at the same time, it bounces the chili peppers on the upper side of the spring tooth away and transports them into the interior of the feeding hopper.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this chain-conveyed chili pepper picking device, multiple spring teeth secure the chilies during transport. As the chilies are transported to the upper side of the feeding hopper, one end of each spring tooth gradually contacts a stop bar. As the spring tooth continues to move downwards, the stop bar presses it down. After passing the stop bar, a pressure spring immediately springs the spring tooth up, simultaneously dislodging the chilies on the upper side of the spring tooth and conveying them into the feeding hopper. This device automatically dislods the chilies on the upper side of the spring teeth when conveying them to the upper side of the feeding hopper, preventing some chili pepper stems from getting stuck between multiple spring teeth and thus preventing the chilies from being conveyed into the feeding hopper, thereby improving the device's chili pepper picking efficiency.
