Description

Technical Field

[0001] This utility model relates to the field of agricultural automation equipment technology, and in particular to an adjustable tassel-supporting device for a radish harvester. Background Technology

[0002] The mechanized harvesting of white radishes is a key link in the development of modern agriculture. Among them, the top-supporting device is responsible for stably holding the stems and leaves (i.e., radish tops) of the radish before it is pulled out of the soil, and is one of the core components that determines the success rate and integrity of the harvest.

[0003] In actual agricultural production, white radishes grown in the field often exhibit individual differences; even in the same plot, their growth height and the portion exposed above ground vary. Furthermore, different growers or different plots may use different planting row spacing standards.

[0004] The top-lifting devices on some existing radish harvesters typically have fixed operating heights and lateral clamping distances. This "one-size-fits-all" design reveals significant limitations in adaptability when faced with the complex field conditions described above. When the height or spacing of the top-lifting device is mismatched, it can lead to unstable clamping and slippage during harvesting, or even damage to the radish's skin or tops, affecting its commercial value and severely restricting the efficiency and quality of mechanized harvesting.

[0005] Therefore, this utility model proposes an adjustable tassel-supporting device for a white radish harvester to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the existing technology, the tassel-supporting device of the radish harvester has a fixed tassel-supporting height and lateral spacing, which has poor adaptability to radishes with different growth conditions and is prone to harvesting failure or radish damage. The present invention aims to provide an adjustable tassel-supporting device for a radish harvester with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an adjustable tassel-supporting device for a white radish harvester, including: a fixed frame, a movable plate, and a tassel-supporting assembly, as well as a first adjustment mechanism and a second adjustment mechanism.

[0008] The first adjustment mechanism includes a threaded rod rotatably connected to the fixed frame and a guide rod fixed to the fixed frame. The movable plate is threadedly engaged with the threaded rod and slidably engaged with the guide rod.

[0009] Furthermore, the second adjustment mechanism includes a slide rod fixed to the tassel assembly and a slot opened in the movable plate. The slide rod is slidably engaged with the slot. The second adjustment mechanism also includes a locking nut that is threadedly connected to the slide rod.

[0010] Preferably, the first adjusting mechanism further includes a handwheel, which is coaxially fixed to the threaded rod.

[0011] Preferably, a limit plate is fixed to the end of the guide rod.

[0012] Preferably, a protrusion is fixed on the slide bar, and the protrusion is accommodated in the slot.

[0013] Preferably, the tassel-supporting assembly includes a first tassel-supporting plate and a second tassel-supporting plate, and the first tassel-supporting plate and the second tassel-supporting plate are fixedly connected by a bracket.

[0014] Preferably, the slide bar is fixed to the bottom of the first tassel plate.

[0015] Preferably, the tassel-supporting chain drive is located on the inner surfaces of the first tassel-supporting plate and the second tassel-supporting plate that are directly opposite each other.

[0016] Preferably, the device further includes a conveyor plate connected to the rear of the fixed frame.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a first adjustment mechanism consisting of a handwheel, a threaded rod, and a movable plate, the problem that the height of the existing harvester's tassel-supporting device is fixed and cannot adapt to white radishes of different growth heights is solved. This achieves the technical effect of being able to conveniently and accurately adjust the working height of the tassel-supporting component, thereby improving the harvest success rate and the radish integrity rate.

[0018] 2. In this utility model, by setting a second adjustment mechanism consisting of a slide bar, a slot and a locking nut, the problem of fixed lateral spacing of the existing harvester tassel-supporting device and difficulty in aligning with white radishes with different planting row spacings is solved. This achieves the technical effect of being able to quickly adjust the lateral position of the tassel-supporting component, accurately clamping white radishes with different row spacings, and improving work efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figures 1 to 4 This utility model provides an adjustable tassel-supporting device for a radish harvester, which aims to solve the problem of poor adaptability of existing radish harvester tassel-supporting devices to radishes of different growth heights and planting spacings.

[0023] like Figure 1 As shown, the adjustable tassel-supporting device of the radish harvester includes a fixed frame 201 and a movable plate 204 that can be vertically slidably connected to the fixed frame 201. The fixed frame 201 serves as the mounting base for the entire device, while the movable plate 204 is used to support the tassel-supporting assembly 4 and achieve vertical lifting and lowering movement. To achieve the lifting and lowering adjustment of the movable plate 204, the device includes a first adjustment mechanism 2, as shown in the figure. Figure 1 and Figure 2 The first adjusting mechanism 2 includes a threaded rod 203 and a guide rod 205. The threaded rod 203 is rotatably connected to the fixed frame 201 and threadedly engaged with the movable plate 204. The guide rod 205 is fixed to the fixed frame 201, and the movable plate 204 is slidably engaged with the guide rod 205. Specifically, a handwheel 202 is coaxially fixed to one end of the threaded rod 203. By rotating the handwheel 202, the threaded rod 203 can be driven to rotate around its own axis. The rotation of the threaded rod 203 is achieved through the engagement of its external thread with the internal thread on the movable plate 204. The movable plate 204 slides linearly along the guide rod 205, thereby adjusting the vertical height of the movable plate 204. The guide rod 205 provides stable guidance for the lifting and lowering movement of the movable plate 204, preventing it from shaking or deflecting during movement and ensuring the smoothness of the adjustment process. A limit plate 206 is also fixed at the end of the guide rod 205. The limit plate 206 can prevent the movable plate 204 from moving excessively and dislodging from the threaded rod 203 or the guide rod 205 when adjusting downwards, thus playing a protective role in limiting the stroke.

[0024] To address the adaptability issue caused by varying planting spacing in white radish harvesters, the adjustable tassel-supporting device includes a tassel-supporting assembly 4 and a second adjustment mechanism 5 for adjusting the lateral position of the tassel-supporting assembly 4. The tassel-supporting assembly 4 is adjustablely connected to the movable plate 204 via the second adjustment mechanism 5. Please refer to [link / reference needed]. Figure 1 , Figure 3 and Figure 4 The core adjustment structure is described in detail below: The second adjustment mechanism 5 includes a slide rod 501 fixed to the tassel assembly 4 and a slot 504 opened inside the movable plate 204. The slide rod 501 slides within the slot 504, allowing the tassel assembly 4 to move laterally relative to the movable plate 204. A protrusion 503 is fixed on the slide rod 501, and the protrusion 503 is also housed inside the slot 504. The protrusion 503 serves as a reference for the lateral adjustment position, and its structural dimensions are larger than the width of the slot 504, effectively preventing the slide rod 501 from dislodging from the slot 504. The second adjustment mechanism 5 also includes a locking nut 502, which passes through the movable plate. 204 is threadedly connected to the slide bar 501. When the spacing needs to be adjusted, loosen the locking nut 502 to release the locking force on the slide bar 501. After moving the tassel support assembly 4 to the predetermined position, tighten the locking nut 502 again to securely lock the slide bar 501 in the designated position in the slot 504, thereby achieving reliable fixation of the lateral spacing. The tassel support assembly 4 itself includes a first tassel support plate 401 and a second tassel support plate 402. The first tassel support plate 401 and the second tassel support plate 402 are fixedly connected by a bracket. The slide bar 501 is fixed to the bottom of the first tassel support plate 401. The tassel support chain 3 is driven on the inner surfaces of the first tassel support plate 401 and the second tassel support plate 402 facing each other, and is used to clamp and transport the radish tassels during harvesting operations.

[0025] Based on the above embodiments, the present invention may further include the following preferred technical solutions: To facilitate effortless adjustment by the operator, the first adjustment mechanism 2 also includes a handwheel 202, which is coaxially fixed to the threaded rod 203. To prevent the movable plate 204 from dislodging due to excessive movement during adjustment, a limit plate 206 is fixed to the end of the guide rod 205. To facilitate observation of the lateral adjustment position and simultaneously serve as a limit and anti-dislodgement function, a protrusion 503 is fixed on the slide rod 501, which is accommodated in the slot 504. The tassel-supporting assembly 4 specifically includes a first tassel-supporting plate 401 and a second tassel-supporting plate 402. The first tassel-supporting plate 401 and the second tassel-supporting plate 402 are fixedly connected by a bracket, and the slide rod 501 is fixed to the bottom of the first tassel-supporting plate 401. To achieve dynamic clamping and conveying of the radish tassels, a tassel-supporting chain 3 is provided on the inner surfaces of the first tassel-supporting plate 401 and the second tassel-supporting plate 402 facing each other. To guide the harvested radishes to the collection device, a conveyor plate 1 is also included, which is connected to the rear of the fixed frame 201.

[0026] Working principle: When the height of the tassel-supporting assembly 4 needs to be adjusted to accommodate radishes of different heights, turn the handwheel 202. The handwheel 202 drives the threaded rod 203 to rotate. Since the threaded rod 203 and the movable plate 204 are threadedly engaged, the rotation of the threaded rod 203 is converted into the vertical linear movement of the movable plate 204 along the guide rod 205, which in turn drives the tassel-supporting assembly 4 connected to the movable plate 204 to achieve overall lifting and lowering, thereby accurately matching the growth height of the radish. When it is necessary to adjust the lateral spacing of the tassel support assembly 4 to adapt to different planting row spacings, first loosen the locking nut 502 to release the locking of the slide rod 501. At this time, the first tassel support plate 401 can be moved horizontally, and the slide rod 501 at its bottom slides in the slot 504 of the movable plate 204. The protrusion 503 moves accordingly. After adjusting to the preset position, tighten the locking nut 502 again to fix the tassel support assembly 4 firmly in the new lateral position. After the height and spacing are adjusted, during the harvesting operation, the radish support chain 3 on the radish support assembly 4 works together to clamp and transport the radish tops. The pulled-out radishes are conveyed to the subsequent collection device via the conveyor plate 1. Through the coordinated action of the first adjustment mechanism 2 and the second adjustment mechanism 5, this utility model effectively solves the problem of poor adaptability caused by the different sizes and planting specifications of the radishes.
