[0042] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0043] See also Figure 1-10 As shown, the utility model provides a semi-automatic radish harvester, including a core harvesting mechanism 100, a frame mechanism 200 and an automatic lifting mechanism 300; wherein, the core harvesting mechanism 100 is mounted on the frame mechanism 200. The core harvesting mechanism 100 includes a harvesting end and an unloading end, the harvesting end is movably connected to the frame mechanism 200, and the unloading end is connected to the frame mechanism 200 through the automatic lifting mechanism 300. By rising or falling of the automatic lifting mechanism 300, the height of the unloading end can be adjusted, and the height of the harvesting end also changes accordingly, so as to adjust the height of the harvesting end from the ground to adapt to different terrains and changes in the height of the radishes leaking from the ground.

[0044] Specifically, see Figure 1-5 As shown, the harvesting end of the core harvesting mechanism 100 includes a harvesting port 102, two loosening and leaf collecting rollers 101 and a lifting plate 104, and the lifting plate 104 is arranged below the harvesting port 102. The harvesting port 102 is formed by two parallel conveyor belts 103, and the two loosening and leaf collecting rollers 101 are spiral-shaped rollers. The rotation of the rollers can not only loosen the soil, but also have the function of shrinking the leaf stems to the harvesting port 102, so as to more accurately send the leaf stems into the conveyor belt 103, ensuring that the radish can be pulled up more easily.

[0045] In addition, in order to cope with the situation that the radish is still difficult to pull up, a specially designed oblique lifting plate 104 is provided. When the radish cannot be pulled up by the conveyor belt smoothly, the lifting plate 104 will lift the radish in time, thereby ensuring that each radish can be successfully pulled up by the conveyor belt.

[0046] The core harvesting mechanism 100 includes a first horizontal frame 114 arranged at the harvesting end, a second horizontal frame 115 arranged at the unloading end, and a first bracket 116 and a circular guide rod 113 which are respectively vertically connected to the first horizontal frame 114 and the second horizontal frame 115; the automatic lifting mechanism 300 is connected to the circular guide rod 113.

[0047] The conveyor belt 103 is arranged below the first horizontal frame 114, the second horizontal frame 115 and the first bracket 116, that is, it extends from the harvesting end to the unloading end, and is used to pull the radish from the harvesting end and transport it to the unloading end for subsequent processing. A cutter 105 is arranged below the conveyor belt 103 at the unloading end, which is used to cut off the radish fruit and tassel leaves. A second motor 111 is arranged above the second horizontal frame 115, and the second motor 111 is connected to the second gear 110 through a second rotating shaft, and the second gear 110 is connected to the conveyor belt 103 through a third rotating shaft; the second rotating shaft is also connected to the third gear 112 through a transmission chain, and the third gear 112 is connected to the cutter 105 through a fourth rotating shaft.

[0048] The conveyor belt 103 is the core device of the whole system for clamping and pulling radishes. Through a small gap, the conveyor belt 103 can firmly clamp the leaf stems of the radishes to ensure that the radishes will not fall off or slide during the movement. The speed of the conveyor belt 103 can be accurately controlled by adjusting the speed of the second motor 111, thereby ensuring the efficiency and stability of the radish transmission.

[0049] In particular, a radish cleaning device (not shown) is provided below the conveyor belt 103 between the harvesting end and the unloading end, which is used to pre-treat the pulled radishes, and its function is to clean the dirt and broken leaves on the surface of the radishes, and improve the overall quality and appearance of the radishes. Through the pneumatic motor, the water in the water tank is pressed to the high-pressure nozzle by air pressure and sprayed out, and the radishes in transportation can be cleaned to remove the dirt attached to the radishes, and the radishes are pre-treated for easy storage and transportation.

[0050] At the end of the radish conveying, the radish and its stem need to be cut off and then fall into the storage box on the notched disc 201 below, so a fast cutter 105 needs to be designed to separate the radish from the stem. Considering that the radish is continuously conveyed on the conveyor belt, a three-leaf blade can be selected to ensure that each radish can be cut off in time and accurately and fall into the collection box smoothly.

[0051] The loosening leaf collecting roller 101 is arranged above the first horizontal frame 114 and is arranged obliquely downward to facilitate extension into the soil; a first motor 109 is arranged above the first bracket 116, and two loosening leaf collecting rollers 101 are respectively connected to two meshing first gears 108 through two universal couplings 106, and one of the first gears 108 is connected to the first motor 109 through a first rotating shaft. In order to facilitate the installation of the first motor 109 and other components, a first frame 107 is arranged above the first bracket 116 to improve the overall stability of the device. The rotation of the first motor 109 drives the two meshing first gears 108 to rotate, and then drives the two loosening leaf collecting rollers 101 to rotate. When facing a field with relatively compact soil, it is particularly difficult to pull out radishes by simply relying on the conveyor belt to clamp the leaf stems. Therefore, the added loosening leaf collecting roller 101 can loosen the soil around the radish. At the same time, considering that the radish leaves are disorderly, the loosening and leaf collecting roller 101 can also be designed to gather the leaf stems of the radish so that the harvesting port 102 can clamp them more effectively.

[0052] See also Figure 8 The automatic lifting mechanism 300 includes a second frame 306 and a guide rail 302 arranged on the second frame 306; a third motor 304 and a first reducer 305 are arranged on the guide rail 302; a guide shaft matching opening 301 is arranged on the third motor 304, and the guide shaft matching opening 301 is connected to the third motor 304 through a hinge 302; the circular guide rod 113 is sleeved in the guide shaft matching opening 301, and the bottom of the second frame 306 is mounted on the frame mechanism 200.

[0053] The automatic lifting mechanism 300 is used to adjust the height of the harvesting opening 102 of the core harvesting mechanism 100. Its core components are the shaft fixing part and the hinge. The guide shaft matching opening 301 can move along the length direction of the guide rail. Through this mechanism, the rear end height of the circular guide rod 113 of the core harvesting mechanism 100 can be effectively raised or lowered, thereby realizing the precise adjustment of the height of the harvesting opening 102 of the core harvesting mechanism 100. Adjusting the height of the harvesting opening 102 can improve the adaptability of the machine to different ground surfaces, and improve the ability to harvest white radishes of different heights, reducing missed harvests. Radishes of different types and sizes (carrots, white radishes) can be harvested, and even other root crops, such as beets, can be effectively harvested.

[0054] See also Figure 6 and 7The frame mechanism 200 includes a second bracket 206, a third bracket 207, a fourth bracket 208, a fifth bracket (not shown in the figure, located on the opposite side of the fourth bracket 208) and a sixth bracket. The second bracket 206 and the third bracket 207 are parallel to the circular guide rod 113, the fourth bracket 208 is vertically connected to the third bracket 207, the fifth bracket is vertically connected to the second bracket 206, and the sixth bracket is vertically connected to the fourth and fifth brackets; the ends of the second bracket 206 and the third bracket 207 are arranged in parallel. The bottoms of the second bracket 206 and the third bracket 207 are both connected to rollers 205; and the two ends of the sixth bracket are respectively connected to a roller 205. The harvesting end of the core harvesting mechanism 100 is mounted on the fourth bracket 208, and the bottom of the second frame 306 is mounted on the third bracket 207.

[0055] In particular, the frame mechanism 200 further includes a notched disc 201 disposed between the second bracket 206, the third bracket 207 and the fourth bracket 208, for placing a storage box; a cross rotating device 203 is disposed on the notched disc 201, and a first slideway 204 is disposed at the notch of the notched disc 201. The storage box is used to collect the cut radishes, and the cross rotating device 203 pushes the storage box to a working position. When the storage box is full, the cross rotating device 203 pushes the storage box away from the notched disc 201 and slides out from the first slideway 204. At the same time, the fourth motor 403 pushes another empty storage box to the notched disc, and reciprocates therebetween.

[0056] The fifth bracket is fixed with an inclined leaf unloading plate 202, which is arranged below the conveyor belt 103 at the unloading end. The radish is transported upward to the position of the cutter 105, which cuts off the radish fruit and tassels, and the radish fruit falls into the storage box below, while the tassels continue to move with the conveyor belt 103, fall onto the leaf unloading plate 202 at the rear, and return to the field to provide nutrients for sowing next year.

[0057] The sixth bracket is fixed with a pneumatic motor 209 and a cylinder 210. The pneumatic motor 209 is responsible for pumping air into the cylinder 210. Then the high-pressure air in the cylinder 210 flows along the air guide pipe to the nozzle and is ejected from the nozzle. The nozzle can be placed at Figure 6 On the small component on the middle left of the fourth bracket 208, the direction is aligned with 2 to 3 cm below the conveyor belt 103, which is used to spray high-pressure airflow to wash the radish.

[0058] See also Fig. 9 and 10 The semi-automatic radish harvester also includes an empty box storage mechanism 400 and an empty box slide mechanism 500; the empty box slide mechanism 500 is respectively connected to the empty box storage mechanism 400 and the notched disc 201, and the empty box storage mechanism 400 is used to transport the storage box to the notched disc 201 through the empty box slide mechanism 500.

[0059] The empty box storage mechanism 400 includes a third frame 405, a fourth motor 403 and a second reducer 404 arranged on the third frame 405, a push rod 402 is connected to the second reducer 404, and a stop plate 401 forming a rectangular frame is arranged at the other end of the push rod 402; the empty box slide mechanism 500 includes a fourth frame 503 and a second slide 501 arranged on the fourth frame 503, and baffles 502 are arranged on both sides of the second slide 501. The movement of the fourth motor 403 drives the second reducer 404, and the second reducer 404 is engaged with the rack of the push rod 402, so that the fourth motor 403 and the second reducer 404 move on the rack track, and then the front push rod 402 pushes the empty storage box to slide out of the empty box storage mechanism and fall into the second slide 501.

[0060] In particular, the sixth bracket is provided with a lighting device 211 and an ultrasonic distance measuring device 212. The ultrasonic distance measuring device is a key device for detecting obstacles ahead and realizing operations such as automatic turning. The ultrasonic distance measuring device can, on the one hand, stop the machine in time when encountering obstacles or people ahead to avoid safety accidents; on the other hand, by setting a baffle and cooperating with programming, operations such as automatic turning can be realized, thereby realizing automated harvesting.

[0061] Specifically, the ultrasonic distance measuring device 212 emits ultrasonic waves forward, and returns when encountering an obstacle, and is received by the receiving device. When there is a person in front, the distance detected by the ultrasonic distance measuring device 212 will be less than the safety value, the machine will issue a warning, and immediately stop the machine to prevent safety accidents. If it is working in a semi-automatic operation mode, a baffle can be set at a certain distance to control the travel distance of the machine, and the machine can be stopped at a certain distance from the baffle. The programming can be used to realize operations such as turning to realize semi-automatic harvesting. Therefore, the machine only needs at least one person to supervise whether there are empty boxes in the empty box storage device and the operating status of each device of the machine. The utility model can realize semi-automatic harvesting with only a very small amount of manual supervision by programming the machine in combination with the ultrasonic distance measuring device.

[0062] In order to improve the automation of the machine and better display the working status of each part, three indicator lights are installed in front of the vehicle, corresponding to the vehicle driving status, the core mechanism lifting and lowering status, and the core mechanism operating status. It may be difficult for the driver to evaluate whether the core device is lifted and lowered by the naked eye, so the indicator light can better help the driver judge whether the core harvesting mechanism 100 has entered the appropriate operating position and whether the machine can be driven to start moving. At the same time, it provides a reference for other people except the driver, warning people next to the vehicle not to get close to the lifting and lowering and operating core harvesting device to avoid accidents.

[0063] Specifically, when the harvesting mouth 102 of the machine has not entered the working position and the machine is moving, the lighting device lights up green, when the automatic lifting mechanism 300 rises or descends, the lighting device 211 lights up yellow, and when the harvesting mouth 102 of the machine is in the working position and the core harvesting mechanism is working, the lighting device lights up red, which serves to warn personnel.

[0064] The working principle of the semi-automatic radish harvester provided by the utility model is:

[0065] First is the harvesting process. The automatic lifting mechanism 300 rises or falls through the third motor 304 of the track, controls the height of the rear end of the guide rail 303, and uses the lever principle to adjust the height of the harvesting port 102 of the core harvesting mechanism 100, which can adapt to the harvesting of different types of radishes and other root crops. Then, when the harvesting port 102 is at a suitable height, the loosening and leaf collecting roller 101 and the conveyor belt 103 start to operate, and the semi-automatic radish harvester moves forward to start harvesting. The loosening and leaf collecting roller 101 loosens the soil near the radish and gathers the radish tassels to the middle, so that the conveyor belt 103 can clamp the tassels. As the machine moves forward, the radish tassels are clamped by the conveyor belt 103 and lifted upward. The lifting plate 104 below lifts the radish for easy clamping and prevents the radish from being missed.

[0066] The following is the transportation process. The radish leaves are clamped by the conveyor belt 103 and transported upward along with the conveyor belt 103. While the radish is being transported by the conveyor belt 103, the air pump cleaning device (comprising the pneumatic motor 209 and the cylinder 210) sprays a high-pressure airflow to wash away the soil and broken leaves on the surface of the radish.

[0067] The collection process is then followed. As the radish continues to be transported upward to the position of the cutter 105, the cutter 105 cuts off the radish fruit and the tassel leaves, and the radish fruit falls into the storage box below, while the tassel leaves continue to move along the conveyor belt 103, fall onto the leaf unloading plate 202 at the rear, and return to the field to provide nutrients for sowing next year.

[0068] Finally, there is the collection process. When the storage box is full, the cross rotating device 203 rotates 90 degrees to send the storage box out of the disc 201 and drops it into the first slide 204. The storage box slides on the first slide 204 to the right side of the machine. Then the track fourth motor 403 in the empty box storage mechanism 400 sends an empty box from the second slide 501 into the disc 201, and the cross rotating device 203 sends the empty box at the connecting position to the collection position and the empty box at the entering position to the connecting position, completing a collection cycle.

[0069] In summary, the semi-automatic radish harvester provided by the utility model can integrate harvesting, transportation, collection, unloading, indication, safety and automatic control. At the same time, an automatic lifting device is introduced to adjust the height of the harvesting opening to adapt to different terrains and the changes in the height of the radish leaking out of the ground, solving the problems of serious damage to radishes and high leakage rate in the existing harvesting process. The utility model realizes the automation and efficiency of the harvesting process through the improvement of the mechanical structure, thereby improving the harvesting efficiency of white radishes, reducing labor costs, and building a more complete harvesting system.
