Description

Technical Field

[0001] This utility model relates to the field of radish harvesting technology, and more specifically, to a radish harvesting mechanism. Background Technology

[0002] A radish harvesting machine refers to a mechanical device or apparatus used for harvesting radishes. It can automatically or semi-automatically complete the harvesting of radishes, has a high working capacity, and can complete the harvesting of a large number of radishes in a short period of time. Compared with traditional manual harvesting, the machine operates faster, which can significantly improve harvesting efficiency, save time and labor costs, and reduce the risks of manual labor. It is of great significance to farmers and agricultural production.

[0003] Chinese Patent Publication No. CN211656875U discloses a double-row carrot harvesting assembly. The central frame includes an upper frame plate and a lower frame plate fixed together. Left inner harvesters that push the left row of carrot stems and leaves backward and upward, and right inner harvesters that push the right row of carrot stems and leaves backward and upward, are respectively installed on the left and right sides of the central frame. The left inner harvester includes a left roller and a left belt; the right inner harvester includes a right roller and a right belt. The advantages are: when used in conjunction with the left and right conveyor devices, it can simultaneously harvest and cut two rows of carrots. During the harvesting process, the carrot stems and leaves are less likely to entangle or clog, the operation is stable, and the carrot harvesting efficiency is doubled.

[0004] Because different varieties of radishes produce radishes of varying sizes, the devices described above cannot adjust the spacing between the radishes being clamped. If they cannot accommodate radishes of different sizes, incomplete separation or excessive damage may occur during harvesting, affecting the harvesting quality and resulting in problems such as cuts, breakage, or unstable quality in the harvested radishes.

[0005] Therefore, it is necessary to provide a radish harvesting organization to solve the above problems. Utility Model Content

[0006] This invention provides a radish harvesting mechanism that can improve upon existing technologies that cannot adapt to radishes of different sizes, leading to incomplete separation or excessive damage during harvesting. This affects harvesting quality and results in problems such as cuts, breakage, or unstable quality in the harvested radishes.

[0007] This application provides a radish harvesting mechanism, including two main frames. Each main frame has a mounting bracket fixedly connected to its bottom end. Each main frame has a conveying assembly at its bottom end, and both main frames are inclined. A collecting assembly is located below the conveying assembly, and an adjusting assembly is located at the top of the conveying assembly. A cutting assembly is located inside the main frames. The adjusting assembly includes a mounting plate and a threaded rod, which passes through the mounting plate and is threadedly connected to it. The conveying assembly includes two drive motors, each with its top end fixedly connected to the bottom end of the mounting plate. Each drive motor's output end is keyed to a drive pulley.

[0008] The technical solution described above in this application embodiment has at least the following technical effects: the drive belt rotates by the cooperation of the drive pulley and the driven pulley, and the radish tops are clamped between the two drive belts for conveying. The adjustment component is mainly used to adjust the distance between the drive pulley and the driven pulley. Since the length of the drive belt is fixed, when the distance between the drive pulley and the driven pulley becomes smaller, the drive belt will become looser. At the same time, the drive belt has elasticity, and the radish clamped between the drive belts will stretch and deform the drive belts. By changing the tension of the drive belts, it can be adapted to radishes of different sizes.

[0009] In some embodiments, the adjustment assembly further includes a fixing block, which is fixedly connected to the inner side of the main frame, and one end of the threaded rod is rotatably connected to the fixing block.

[0010] In some embodiments, the adjustment assembly further includes two limiting frames, both of which are fixedly connected to the outer end of the main frame. Two sliders are fixedly connected to the top of the mounting plate. The two sliders are symmetrically distributed about the threaded rod as the central axis, and the sliders are adapted to the limiting frames. The sliders are slidably connected to the limiting frames.

[0011] In some embodiments, the conveying assembly further includes two drive belts and two driven pulleys. The top of the driven pulleys is rotatably connected to the main frame, and the driven pulleys are driven to the drive pulleys via the drive belts. Two guide plates are fixedly connected to the outer end of the main frame, and the guide plates are located above the driven pulleys.

[0012] In some embodiments, the conveying assembly further includes two fixed frames, both of which are fixedly connected to the outer end of the main frame. Each of the two fixed frames is equipped with a pulley group on one side close to the other, and the outer end of the transmission belt abuts against the pulley group.

[0013] In some embodiments, the collection assembly includes a housing, with a collection port one and a collection port two respectively provided at the outer end of the housing, and a buffer frame installed at the bottom of the housing.

[0014] In some embodiments, the cutting assembly includes a connecting frame, which is fixedly connected to the main frame. A second drive motor is installed at the outer end of the connecting frame, and a cutting blade is installed at the output end of the second drive motor. Attached Figure Description

[0037] A radish harvesting machine refers to a mechanical device or apparatus used for harvesting radishes. It can automatically complete the harvesting of radishes, improve harvesting efficiency and reduce labor costs. However, due to different varieties of radishes, the size of the radishes grown will also vary.

[0038] If the spacing between the radishes cannot be adjusted, it will not be able to accommodate radishes of different sizes. If the spacing is too large, the radishes will not be clamped tightly during harvesting and will fall during the conveying process, requiring manual adjustment or intervention. This will cause the harvesting process to stop and be delayed, thereby reducing harvesting efficiency. If the clamps are too tight, the radishes will be damaged, resulting in problems such as cuts, breakage, or unstable quality of the harvested radishes.

[0039] Based on this, it is possible to improve the existing technology that cannot adapt to radishes of different sizes, which may lead to incomplete separation or excessive damage during harvesting. This will affect the harvesting quality and cause problems such as cuts, damage or unstable quality of the harvested radishes.

[0040] Please see Figures 1-5 A radish harvesting mechanism includes two main frames 1, each with a mounting frame 7 fixedly connected to its bottom end. A conveying assembly 3 is provided at the bottom end of each main frame 1, and both main frames 1 are inclined. A collecting assembly 2 is provided below the conveying assembly 3, and an adjusting assembly 4 is provided at the top of the conveying assembly 3. A cutting assembly 5 is provided inside the main frame 1. The adjusting assembly 4 includes a mounting plate 41 and a threaded rod 44, which passes through the mounting plate 41 and is threadedly connected to it. The conveying assembly 3 includes two drive motors 31, each with its top end fixedly connected to the bottom end of the mounting plate 41. A drive pulley 32 is keyed to the output end of each drive motor 31.

[0041] The device in this design is primarily mounted on a radish harvester and requires a power unit for traction. It also necessitates the use of devices for loosening soil, digging, and tassel lifting. The dual-harvesting platform design effectively improves efficiency. The mounting frame 7, fixed at the bottom of the main frame 1, is mainly used for mounting on the harvesting vehicle. The two main frames 1 are designed side-by-side and are inclined. Two guide plates 8 are fixed at the downward-sloping end of the main frame 1. The guide plates 8 are mainly used for guiding the radishes to the space between the two drive belts 33. A conveying assembly 3 is installed below the main frame 1. The conveying assembly 3 is mainly used for... The radish is conveyed to the collecting component 2. At the end of the conveying component 3, that is, the upwardly inclined end of the main frame 1, a cutting component 5 is installed. The cutting component 5 is mainly used to cut off the radish tops and separate them. At the same time, an adjusting component 4 is installed at the upwardly inclined end of the main frame 1. The adjusting component 4 is mainly used to adjust the distance between the driving pulley 32 and the driven pulley 34. By adjusting the distance between the driving pulley 32 and the driven pulley 34, the tension of the transmission belt 33 can be changed. Various radishes can be harvested efficiently without frequent adjustments or manual intervention, which improves the working efficiency of the harvester and saves time and labor costs.

[0042] Optionally, in some embodiments, please refer to Figure 1 and Figure 5 The adjustment component 4 also includes a fixing block 42, which is fixedly connected to the inner side of the main frame 1, and one end of the threaded rod 44 is rotatably connected to the fixing block 42.

[0043] The adjustment assembly 4 also includes two limit frames 43, both of which are fixedly connected to the outer end of the main frame 1. Two sliders 45 are fixedly connected to the top of the mounting plate 41. The two sliders 45 are symmetrically distributed with the threaded rod 44 as the central axis, and the sliders 45 are adapted to the limit frames 43. The sliders 45 and the limit frames 43 are slidably connected.

[0044] Two of the limiting brackets 43 are made of the same material and have the same shape as the main frame 1. They are fixed to the upwardly inclined end of the main frame 1 to assist the mounting plate 41 in moving and adjusting. Two sliders 45 are fixed to the top of the mounting plate 41 for sliding with the limiting brackets 43. At the same time, the fixing block 42 is also fixed to the main frame 1 and located on the inner side of the main frame 1. One end of the threaded rod 44 passes through the mounting plate 41 and the other end is rotatably connected to the fixing block 42. The threaded rod 44 is threadedly connected to the mounting plate 41. A drive motor 31 is installed at the bottom of the mounting plate 41. Therefore, by rotating the threaded rod 44... This allows the mounting plate 41 to drive the drive motor 31 to move, thereby adjusting the distance between the driving pulley 32 and the driven pulley 34. Since the length of the transmission belt 33 is fixed, when the distance between the driving pulley 32 and the driven pulley 34 decreases, the transmission belt 33 will become looser. At the same time, the transmission belt 33 is elastic, and the carrots clamped between the transmission belt 33 will stretch and deform the transmission belt 33. By adjusting the distance between the driving pulley 32 and the driven pulley 34, the tension of the transmission belt 33 can be changed, thus adapting it to carrots of different sizes.

[0045] Optionally, in some embodiments, please refer to Figure 3 and Figure 4 The conveying assembly 3 also includes two drive belts 33 and two driven pulleys 34. The top of the driven pulleys 34 is rotatably connected to the main frame 1. The driven pulleys 34 are connected to the drive pulleys 32 via the drive belts 33. Two guide plates 8 are fixedly connected to the outer end of the main frame 1. The guide plates 8 are located above the driven pulleys 34.

[0046] The conveying assembly 3 also includes two fixed frames 35, both of which are fixedly connected to the outer end of the main frame 1. Each of the two fixed frames 35 is equipped with a pulley block 36 on one side close to the other, and the outer end of the transmission belt 33 abuts against the pulley block 36.

[0047] The driven pulley 34 mentioned above is rotatably connected to the bottom end of the downwardly inclined part of the main frame 1. It is connected to the driving pulley 32 via the transmission belt 33. The driving pulley 32 is driven by the drive motor 31. The fixing frame 35 fixes the bottom end of the main frame 1 and is mainly used to install the pulley block 36. The pulley block 36 is composed of multiple pulleys arranged at equal intervals. The two pulley blocks 36 are located on the outside of the two transmission belts 33 respectively. They are mainly used to cooperate with the transmission belts 33 to stably clamp the radish tops. When the drive motor 31 drives the driving pulley 32 to rotate, the transmission belt 33 can be continuously rotated through the cooperation of the driven pulley 34. Through the clamping of the two transmission belts 33, the radish can be clamped and transported.

[0048] Optionally, in some embodiments, please refer to Figure 2The collection component 2 includes a box 21, with a collection port 1 22 and a collection port 23 respectively provided at the outer end of the box 21, and a buffer base 6 installed at the bottom of the box 21.

[0049] The collecting component 2 is located below the end of the conveying component 3. After the radish is transported by the conveying component 3, it can enter the collecting port 22 or the collecting port 23. When the radish falls into the collecting component 2, it will generate an impact force. A buffer frame 6 is installed at the bottom of the box 21 mainly to buffer and improve its stability.

[0050] Optionally, in some embodiments, please refer to Figure 3 and Figure 4 The cutting assembly 5 includes a connecting frame 51, which is fixedly connected to the main frame 1. A second drive motor 52 is installed at the outer end of the connecting frame 51, and a cutting blade 53 is installed at the output end of the second drive motor 52.

[0051] The cutting component 5 in this solution is mainly used to cut the radish tops and separate them. The connecting frame 51 is fixed on the main frame 1 and located behind the drive pulley 32. The connecting frame 51 is equipped with a second drive motor 52. The second drive motor 52 is mainly used to drive the cutting blade 53 so that the radish tops are cut off by the cutting blade 53 when the radish is transported to the end of the transmission belt 33, thereby improving the degree of automation.

[0052] Working Principle: The device in this design requires power for traction and also needs to be coordinated with other devices such as soil loosening, digging, and tassel support. First, the guide plate 8 guides the radish in front to between the two transmission belts 33. At this time, the drive motor 31 drives the driving pulley 32 to rotate. Through the cooperation of the driven pulley 34, the transmission belt 33 rotates continuously. The two pulley groups 36 are located on the outside of the two transmission belts 33 respectively. Through the clamping of the two transmission belts 33 and the cooperation of the pulley groups 36, the radish can be clamped and transported. Then the radish will fall into the collection port 22 or the collection port 23 and be collected. By rotating the threaded rod 44, the mounting plate 41 can drive the drive motor 31 to move, thereby adjusting the distance between the driving pulley 32 and the driven pulley 34, thus changing the tension of the transmission belt 33, so as to adapt it to radishes of different sizes.

[0053] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
