Description

Technical Field

[0001] This utility model belongs to the field of agricultural harvesting equipment, and in particular, it is a rapid asparagus harvesting device. Background Technology

[0002] Asparagus, a nutritious and economically valuable vegetable, is widely cultivated globally. However, harvesting asparagus presents numerous challenges. Traditional asparagus harvesting relies primarily on manual cutting with hand-held knives, a labor-intensive process requiring harvesters to bend over for extended periods, placing significant strain on their backs and other body parts. While traditional rapid asparagus harvesting devices can meet basic harvesting needs, if their ability to remove impurities is weak after harvesting, dirt, debris, yellow leaves, and other impurities easily adhere to the asparagus's surface. These impurities not only affect the asparagus's cleanliness but may also leave stains on its skin, reducing its marketability.

[0003] A search revealed Chinese patent document (authorization announcement number CN214852868U), indicating that this utility model relates to an asparagus harvesting device, including a main frame, a harvester mounted at the front of the main frame, an inclined conveyor belt and a horizontal conveyor belt connected to the end of the inclined conveyor belt at the rear of the main frame, a shaking mechanism inside the inclined conveyor belt, baffles on both sides of the horizontal conveyor belt along its length, and a brush plate horizontally positioned above the horizontal conveyor belt with a width equal to the distance between the two baffles, bristles at the bottom of the brush plate, and a rotary motor connected to the brush plate at the top of the brush plate, the rotary motor being mounted on the main frame. This utility model can effectively separate asparagus from the soil after harvesting and reduce damage to the asparagus. This device can meet basic harvesting needs; however, if the device's ability to remove impurities is weak after harvesting, dirt, debris, yellow leaves, and other impurities easily adhere to the surface of the asparagus. These impurities not only affect the cleanliness of the asparagus's appearance but may also leave stains on the asparagus's skin, reducing its marketability. Utility Model Content

[0004] The purpose of this invention is to provide a rapid asparagus harvesting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid asparagus harvesting device, comprising a walking frame supporting the rapid harvesting of asparagus, a fixed frame welded inside the walking frame, a screening box movably connected inside the fixed frame, two hollow columns welded to the inner bottom wall of the screening box, springs for buffering connected inside the two hollow columns, a movable column connected to one end of the spring, a screening box for screening and removing impurities from the harvested asparagus installed at the end of the movable column away from the spring, guide columns connected to both ends of the movable column, limit grooves symmetrically arranged on both sides of the screening box, limit rods connected to the outer periphery of the guide columns, and the two ends of the limit rods sliding inside the limit grooves.

[0006] Preferably, the bottom of the walking frame is rotatably connected to walking wheels for movement via a connecting shaft, the inside of the walking frame is equipped with a drive motor for providing power, and the side of the walking frame is equipped with a controller for control.

[0011] Preferably, the surface of the conveyor frame is provided with a feeding port for asparagus to enter, and the bottom of the conveyor frame is connected to a guide hopper.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This rapid asparagus harvesting device benefits from the structure of the screening box and screening container. The connecting shaft between the traveling wheels drives the rotating disc and the eccentric transmission disc to rotate. The eccentric transmission disc drives the movable frame and the movable column to move. The movable column drives one end of the screening box to make a circular motion, generating vibration at one end of the screening box. The screening box drives the hollow column and the screening container to move inside the screening box, vibrating the asparagus inside the screening box and removing impurities from the asparagus. Compared with traditional rapid asparagus harvesting devices, which have weak impurity removal capabilities after harvesting, and where dirt, debris, yellow leaves and other impurities easily adhere to the surface of the asparagus, this structure improves the impurity removal capability, ensures the cleanliness of the asparagus appearance, prevents stains from being left on the asparagus skin, and improves the appearance of the asparagus.

[0014] This rapid asparagus harvesting device benefits from the structure of hollow columns and springs. Due to the action of the springs, the vibration of the screening box inside the screening chamber is buffered, which can protect the asparagus inside the screening box and prevent hard contact between the screening box and the screening chamber, thus protecting the screening box and the screening chamber from damage.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 5The diagram shows a rapid asparagus harvesting device, including a walking frame 1 that supports the rapid harvesting of asparagus. The walking frame 1 is the supporting structure for the entire device, housing other components and ensuring the stability and integrity of the device. A fixed frame 109 is welded inside the walking frame 1. A screening box 3 is movably connected inside the fixed frame 109. Two hollow columns 301 are welded to the inner bottom wall of the screening box 3. Each hollow column 301 has a spring 303 for cushioning connected inside. One end of each spring 303 is connected to a movable column 304. A screening box 305 for screening and removing impurities from the harvested asparagus is installed at the end of the movable column 304 away from the spring 303. Guide columns 302 are connected to both ends of the movable column 304. Limited guides are symmetrically arranged on both sides of the screening box 3. The guide post 302 is connected to the outer periphery of the groove 306 and the limiting rod 307. The two ends of the limiting rod 307 slide inside the limiting groove 306. One end of the screening box 3 vibrates, and the screening box 3 drives the hollow post 301 and the screening box 305 to move inside the screening box 3. This vibrates the asparagus inside the screening box 305, removes impurities from the asparagus, helps remove the soil from the asparagus, makes the soil fall off more easily, and improves the separation effect between the soil and the asparagus. Due to the action of the spring 303, the vibration of the screening box 305 inside the screening box 3 has a buffering effect, which can protect the asparagus inside the screening box 305 and prevent hard contact between the screening box 305 and the screening box 3, thereby protecting the screening box 305 and the screening box 3 from damage.

[0026] The bottom of the walking frame 1 is rotatably connected to the walking wheels 101 for movement via a connecting shaft. The walking wheels 101 serve as the driving wheels for the harvesting device, providing the main forward power for the device and enabling it to move in the asparagus field. The walking frame 1 is equipped with a drive motor 102 for providing power. A controller 103 for control is installed on the side of the walking frame 1 and is connected to the drive motor 102. It can control the rotation of the walking wheels 101 of the device, thereby enabling the device to move in the field.

[0027] A rotating disc 202 is welded to the outer periphery of the connecting shaft between the walking wheels 101. An eccentric transmission disc 204 is rotatably mounted on the side of the walking frame 1. A belt 203 is connected to the outer periphery of the rotating disc 202 and the eccentric transmission disc 204. A movable frame 205 is rotatably connected to the side of the eccentric transmission disc 204. A movable column 206 is rotatably connected to the end of the movable frame 205 away from the eccentric transmission disc 204. The movable part of the movable column 206 is connected to one end of the screening box 3. Finally, it enters the screening box 305 through the guide bucket 201. The connecting shaft between the walking wheels 101 drives the rotating disc 202 and the eccentric transmission disc 204 to rotate. The eccentric transmission disc 204 drives the movable frame 205 and the movable column 206 to move. The movable column 206 drives one end of the screening box 3 to make a circular motion.

[0028] A conveyor frame 104 is welded to the top of the walking frame 1. The surface of the conveyor frame 104 is provided with a feeding port 2 for asparagus to enter. The bottom of the conveyor frame 104 is connected to a guide bucket 201. Two guide frames 105 are welded to the top of the conveyor frame 104 to restrict the movement direction of the asparagus. Multiple conveyor wheels 106 are rotatably installed between the two guide frames 105. The conveyor wheels 106 are equipped with a power motor to provide rotational power to the conveyor wheels 106. This is not an innovative direction of the rapid asparagus harvesting device, so it will not be described in detail. An asparagus harvesting cutter disc 107 for rapid asparagus harvesting is installed at one end of the conveyor frame 104. The asparagus harvesting cutter disc 107 is usually powered by a power source such as an electric motor or a hydraulic motor. This is not an innovative direction of the rapid asparagus harvesting device, so it will not be described in detail. The power source transmits power to the drive shaft of the asparagus harvesting cutter head 107 through a transmission device, such as a belt, chain, or coupling, causing the asparagus harvesting cutter head 107 to rotate at high speed. The traveling wheel 101 drives the traveling frame 1 to move in the area where asparagus needs to be harvested. After the asparagus harvesting cutter head 107 cuts the asparagus, the asparagus reaches the feeding port 2 area through the action of the conveying wheel 106 and the guide frame 105. A toolbox 108 is installed at the other end of the conveying frame 104.

[0029] Working principle

[0030] In use, this rapid asparagus harvesting device uses the traveling wheels 101 to drive the traveling frame 1 to move in the area where asparagus needs to be harvested. After the asparagus is cut by the asparagus harvesting cutter disc 107, it is transported to the discharge port 2 area by the action of the conveying wheels 106 and the guide frame 105, and finally enters the screening box 305 through the guide bucket 201. The connecting shaft between the traveling wheels 101 drives the rotating disc 202 and the eccentric transmission disc 204 to rotate. The eccentric transmission disc 204 drives the movable frame 205 and the movable column 206 to move. The movable column 206 carries... One end of the screening box 3 makes a circular motion, and the screening box 3 vibrates. The screening box 3 drives the hollow column 301 and the screening box 305 to move inside the screening box 3, vibrating the asparagus inside the screening box 305 and removing impurities from the asparagus. Due to the action of the spring 303, the vibration of the screening box 305 inside the screening box 3 has a buffering effect, which can protect the asparagus inside the screening box 305 and prevent hard contact between the screening box 305 and the screening box 3, thereby protecting the screening box 305 and the screening box 3 from damage.
