Description

Technical Field

[0001] This invention relates to the field of scallion cultivation technology, and in particular to a conditioner preparation device and preparation method for reducing continuous cropping obstacles in scallions. Background Technology

[0002] Continuous cropping obstacles for scallions refer to problems caused by continuous planting due to the accumulation of harmful substances or pathogenic microorganisms in the soil. These obstacles reduce the yield and quality of scallions, resulting in economic losses for farmers.

[0003] To address the problem of continuous cropping obstacles in scallion cultivation, many researchers and agricultural experts have been working to find effective methods to improve the soil environment and inhibit the accumulation of harmful substances. One important technique is the use of conditioners to reduce continuous cropping obstacles in scallion cultivation.

[0004] Conditioners that reduce continuous cropping obstacles in scallions are substances that improve the soil environment, reduce the accumulation of harmful substances, and promote scallion growth. These conditioners typically consist of multiple components, including organic matter, inorganic salts, and microorganisms. They function through various mechanisms, such as improving soil structure, providing nutrients, increasing soil microbial activity, and inhibiting the growth of soil-borne pathogens.

[0005] The preparation methods for seasonings can vary depending on the specific formula and requirements. Generally, the process of preparing seasonings includes steps such as raw material preparation, reaction mixing, temperature control, and reaction time. By rationally selecting and proportioning raw materials, and carrying out appropriate reactions and treatments, seasonings that can reduce the obstacles of continuous cropping of scallions can be obtained.

[0006] In the preparation of related technical conditioning agents, the raw materials are mostly mixed manually using tools. This method is not only time-consuming and labor-intensive, but also inconvenient, and the raw materials are not mixed sufficiently, resulting in low efficiency. Summary of the Invention

A first slot is provided at one end of the first cylinder, and a rod is slidably engaged in the first slot. One end of the rod is fixed to the outer wall of the stirring rod, and the other end is elastically connected to the groove wall of the first slot.

[0014] As a further improvement to the above solution, the top of the second cylinder is provided with a third conical tooth that meshes with the first conical tooth, and the center of the third conical tooth has a through hole through which the stirring rod can pass.

[0015] As a further improvement to the above solution, a first roller, a second roller, and a third roller are sequentially installed inside the second cross arm; one side of the first roller contacts and engages with the outer wall of the stirring rod, and the other side contacts and engages with one side of the second roller; the third roller is fixedly sleeved on the outer peripheral side wall of the auger near the top, and the other side of the second roller contacts and engages with the third roller.

[0016] As a further improvement to the above solution, the reactor is provided with a baffle plate, which separates the mixing chamber and the screening chamber from top to bottom.

Detailed Implementation

[0038] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0039] Example 1

[0040] Please combine Figures 1 to 8 A conditioning agent preparation device for reducing the obstacle of continuous cropping of scallions includes a reaction vessel 1, which is a vertical cylindrical structure with an elliptical bottom. The reaction vessel 1 has an input port (not shown) for raw material input on one side and an output port (not shown) at the bottom. A drive shaft 3 capable of periodically rotating at variable speed is concentrically arranged inside the reaction vessel 1. A first cross arm 4 is mounted on the drive shaft 3, and a stirring rod 5 parallel to the drive shaft 3 is mounted on the first cross arm 4. Multiple sets of blades 6 are distributed on the stirring rod 5. An actuation mechanism is mounted on the first cross arm 4. The actuation mechanism is driven by the periodic variable speed rotation of the drive shaft 3, which drives the stirring rod 5 to reciprocate circumferentially.

[0041] The top of the drive shaft 3 extends to the outer side of the top of the reactor 1 and is fixed with a drive gear 17. A motor is installed on the top of the reactor 1, and a toothed gear 16 that intermittently engages with the drive gear 17 is fixed on the motor output shaft. The toothed gear 16 drives the drive gear 17 intermittently through the motor output shaft, thereby realizing the periodic speed change of the drive shaft 3 within the reactor 1, that is, the rotational speed of the drive shaft 3 changes periodically.

[0042] The actuation mechanism includes a bracket (not shown) mounted on the top of the first cross arm 4 and a transmission component mounted on the bracket. The top of the stirring rod 5 is rotatably mounted on the frame of the bracket. A second conical tooth 15 is sleeved and fixed on the outer wall of the stirring rod 5 near the top. A rotating shaft 8 parallel to the first cross arm 4 is inserted into the bracket. One end of the rotating shaft 8 is provided with a first conical tooth 14 that meshes with the second conical tooth 15. The transmission component is driven by the dynamic centrifugal force generated when the stirring rod 5 rotates at a periodic speed change, which can drive the rotating shaft 8 to rotate back and forth. In turn, when the blade 6 moves back and forth in the circumferential direction following the stirring rod 5, the blade 6 is driven to rotate back and forth synchronously, so as to improve the stirring effect and efficiency of the raw materials.

[0043] The transmission assembly includes a first cylinder 7 parallel to the first cross arm 4. A first slot 10 is provided at one end of the first cylinder 7, and a rod 9 is slidably engaged in the first slot 10. One end of the rod 9 is fixed to the outer wall of the stirring rod 5, and the other end is elastically connected to the wall of the first slot 10. A first spring (not shown) is provided between the other end of the rod 9 and the wall of the first slot 10. When the stirring rod 5 is not rotating, the first spring is in a non-deformed state. When the stirring rod 5 rotates, the first cylinder 7 will move centrifugally along the axial direction of the rod 9 under centrifugal force, compressing the first spring. However, since the rotational speed of the stirring rod 5 changes periodically, the centrifugal force on the first cylinder 7 also changes periodically. Therefore, in conjunction with the elastic force of the first spring, the first cylinder 7 can reciprocate along the axial direction of the rod 9.

[0044] The other end of the first cylinder 7 has a second slot 11 into which the rotating shaft 8 can be inserted. The inner wall of the second slot 11 has a spiral-shaped first limiting groove 13. The outer wall of the rotating shaft 8 is fixed with a first limiting block 12 that slides and engages with the first limiting groove 13. When the first cylinder 7 moves axially back and forth, the inner wall of the spiral-shaped first limiting groove 13 will rub against and squeeze the first limiting block 12, forcing the rotating shaft 8 to rotate back and forth, which in turn drives the stirring rod 5 to rotate back and forth through the first bevel tooth 14 and the second bevel tooth 15.

[0045] Furthermore, the conditioning agent preparation device also includes a second cylinder 18 inserted on the first cross arm 4. The second cylinder 18 is concentrically sleeved on the outside of the stirring rod 5, and there is a gap between the second cylinder 18 and the stirring rod 5, so that the second cylinder 18 and the stirring rod 5 can rotate independently without interfering with each other. At least one second cross arm 19 is radially arranged on the outer periphery of the second cylinder 18 near the bottom, and an auger 20 is arranged at the bottom of the second cross arm 19. The top of the second cylinder 18 is provided with a third conical tooth 21 that meshes with the first conical tooth 14, and a through hole is opened in the center of the third conical tooth 21 for the stirring rod 5 to pass through.

[0046] In this embodiment, the rotation of the first bevel tooth 14 can drive the second bevel tooth 15 and the third bevel tooth 21 to rotate synchronously in opposite directions, so that the auger 20 and the stirring rod 5 rotate synchronously but in opposite directions, so that when the raw materials are stirred, the blade 6 and the auger 20 will generate a convection effect, thereby enhancing the stirring and mixing effect and efficiency.

[0047] The second cross arm 19 is equipped with a first roller 23, a second roller 24, and a third roller 25 in sequence. One side of the first roller 23 contacts and engages with the outer wall of the stirring rod 5, and the other side contacts and engages with one side of the second roller 24. The third roller 25 is fixedly sleeved on the outer peripheral side wall of the auger 20 near the top, and the other side of the second roller 24 contacts and engages with the third roller 25.

[0048] The second cross arm 19 is equipped with a track groove 32 that matches the outer periphery of the third roller 25. The axle of the second roller 24 is slidably engaged in the track groove 32 and can rotate relative to the track groove 32. A third spring (not shown) is provided between the axle of the second roller 24 and the groove wall of the track groove 32. When the first roller 23 is pressed by the protrusion 26, it will move along the direction of the slide groove 27 and, while driving the second roller 24, press the second roller 24, forcing the second roller 24 to move along the track groove 32 (the third spring is gradually compressed), so as to ensure effective transmission to the third roller 25.

[0049] In this embodiment, the rotation of the stirring rod 5 can drive the first roller 23, the second roller 24, and the third roller 25 to rotate synchronously, so that the auger 20 itself rotates, further improving the stirring effect on the surrounding raw materials.

[0050] To further improve the stirring coverage and enhance the stirring effect and efficiency of the raw materials, a groove 27 parallel to the second horizontal arm 19 is provided in the second horizontal arm 19 of this embodiment. A slider 28 is slidably connected in the groove 27. A second spring (not shown) is provided between the centrifugal side of the slider 28 and the corresponding groove wall of the groove 27. The axle of the first roller 23 is rotatably inserted into the top of the slider 28. A first connecting rod 30 is vertically fixed at the bottom of the slider 28. A pressure rod 31 parallel to the second horizontal arm 19 is fixed at the bottom of the first connecting rod 30. A limiting sleeve 22 is installed in the second horizontal arm 19 through a coil spring and a coil shaft. The top of the auger 20 is rotatably inserted into the bottom of the limiting sleeve 22. At least two outwardly convex arc-shaped protrusions 26 are provided around the outer peripheral side wall of the stirring rod 5.

[0051] As the stirring rod 5 rotates, causing the auger 20 to rotate, the protrusion 26 on the stirring rod 5 intermittently presses against the first roller 23, forcing the first roller 23 to rotate while bearing pressure and driving the slider 28 to move centrifugally in the groove 27 and squeeze the second spring. At the same time, the slider 28 can also drive the pressure rod 31 to press against the auger 20 through the first connecting rod 30, forcing the auger 20 to deflect outward while rotating, so as to further increase the stirring coverage of the raw materials.

[0052] A partition 2 is provided in the reactor 1, and a mixing chamber and a screening chamber are formed by separating them from top to bottom through the partition 2. A discharge valve (not marked) is provided at the bottom of the partition 2. A sieve plate 33 is inclinedly arranged in the screening chamber. A waste discharge port 34 corresponding to the lower end of the sieve plate 33 is opened on the side wall of the reactor 1.

[0053] In this embodiment, the raw materials stirred and mixed in the mixing chamber enter the sieve plate 33 of the screening chamber through the feeding valve, and the solid particles are screened out to obtain the final conditioning agent.

[0054] It is worth mentioning that, in order to improve the removal efficiency of solid particles, the bottom of the drive shaft 3 in this embodiment passes through the partition plate 2 and extends into the screening chamber, and a fourth conical tooth 35 is fixed thereon. A fifth conical tooth (not shown) that meshes with the fourth conical tooth 35 is installed on the wall of the screening chamber. A disc body 36 is coaxially fixed on the fifth conical tooth. A second limiting block 38 is provided at the eccentric part of the disc surface of the disc body 36. A sliding sleeve (not shown) is fixed on the wall of the screening chamber. A second connecting rod 39 slides through the sliding sleeve. The bottom of the second connecting rod 39 is rotatably connected to the screen plate 33. A waist-shaped second limiting groove 37 is provided at the top. The second limiting block 38 is slidably locked in the second limiting groove 37. The lower end of the screen plate 33 is rotatably connected to the wall of the screening chamber near the waste discharge port 34.

[0055] In other words, when the drive shaft 3 rotates, it can also drive the fifth bevel tooth and the disc 36 to rotate circumferentially through the fourth bevel tooth 35, so that the second limiting block 38 on the disc 36 drives the second connecting rod 39 to move up and down reciprocally through the waist-shaped second limiting groove 37 (and the speed of the second connecting rod 39 moving up and down reciprocally is dynamically changed), so as to continuously change the tilt angle of the sieve plate 33 and improve the removal efficiency and effect of solid particles mixed in the prepared conditioner.
