Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a soil improvement mixer for flue-cured tobacco planting. Background Technology

[0002] Tobacco cultivation has stringent soil requirements; a high-quality soil environment is crucial for ensuring both quality and yield. Suitable soil for tobacco growth requires good aeration, water retention, and a balanced nutrient content. However, long-term monoculture practices, coupled with improper agricultural operations, have led to frequent soil problems in tobacco cultivation. Soil compaction is widespread, porosity has decreased, and aeration and water permeability have deteriorated; soil acidification or alkalization, resulting in pH imbalances and affecting nutrient availability; soil fertility has declined, with deficiencies in macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients such as iron and zinc. These soil problems severely restrict the growth and development of tobacco, leading to stunted plants, yellowing leaves, and weakened disease resistance, ultimately reducing yield and quality. To address these soil problems, soil conditioners have become essential equipment in tobacco cultivation. Traditional soil conditioners can, to some extent, mix soil and conditioner. For example, some soil mixers use rotating blades to agitate the soil, mixing in added organic fertilizers, lime, and other soil conditioners, which improves soil structure and adjusts soil pH to some extent. However, with the expansion of flue-cured tobacco cultivation and the increasing demands for soil improvement, the structural drawbacks of traditional soil mixers have gradually become apparent.

[0003] Traditional soil mixers are extremely inconvenient to repair and replace if the mixing blades or other parts wear out or are damaged during operation. Often, the entire mixer needs to be disassembled, consuming a significant amount of time and labor. For tobacco cultivation, which is time-sensitive, this undoubtedly delays the optimal period for soil improvement and affects the subsequent tobacco planting progress.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] (a) Technical problems to be solved To address the issues raised in the appeal, this utility model provides a soil amendment mixer for flue-cured tobacco planting, thereby resolving the problems mentioned in the background art.

[0006] (II) Technical Solution To address the aforementioned problems, the specific technical solution adopted by this utility model is as follows: A soil conditioner mixer for flue-cured tobacco cultivation includes a mixing chamber body. A feed hopper is installed through the upper surface of the mixing chamber body, and a discharge pipe is installed through the lower surface. An opening is provided through the side surface of the mixing chamber body, and a sealing cover is installed at the opening. A connecting rod is welded between two sealing covers. A crushing roller is installed between the two sealing covers via a sealing bearing seat, and a stirring paddle is installed between the two sealing covers via a sealing bearing seat. The ends of the crushing roller and the stirring paddle are respectively connected to a drive mechanism via couplings. The drive mechanism consists of a reducer and a drive motor, and a reducer is installed at the output end of the drive motor.

[0007] Furthermore, a fixing column is welded to the side surface of the mixing tank body, a damping spring is sleeved on the surface of the fixing column, a fixing plate is provided on the side surface of the damping spring, an eccentric wheel is provided on one side of the fixing plate, and the eccentric wheel is connected to the fixing column through a rotating shaft, and a handle is installed on the side surface of the eccentric wheel.

[0008] Furthermore, the edge of the sealing cover is provided with a groove, and a sealing gasket is embedded in the groove.

[0009] Furthermore, a handle is welded to the side surface of the sealing cover, and a rubber sleeve is fitted onto the surface of the handle.

[0010] Furthermore, a support leg is welded to the lower surface of the mixing tank body, a support leg is welded to the side surface of one of the sealing covers, and a support wheel is bolted to the lower surface of the support pusher.

[0011] Furthermore, an integrated controller is provided on the side surface of the sealing cover.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a soil amendment mixer for flue-cured tobacco planting, which has the following beneficial effects: (1) In this utility model, the crushing roller and the stirring paddle are installed between two sealed covers through a sealed bearing seat, forming a "drawer-type assembly" that can be pulled out as a whole. When the equipment has faults such as wear of the stirring paddle or jamming of the crushing roller, it is not necessary to disassemble the entire mixing box body. Only the sealed cover needs to be opened and the assembly pulled out to complete the component inspection or replacement. Compared with the maintenance method of "complete disassembly" of the traditional fixed mixer, it can save a lot of maintenance time, especially suitable for the "tight agricultural time" characteristics of flue-cured tobacco planting, and avoid delaying the soil improvement window period due to equipment maintenance.

[0013] (2) This utility model adopts an eccentric wheel and a fixed plate structure. When the stirring paddle or crushing roller is inspected or replaced, only the handle needs to be turned (no wrench, screwdriver or other tools are needed). The fixed plate can be loosened by using the eccentric structure of the eccentric wheel so that the staff can inspect and maintain it, which greatly reduces the maintenance time of the equipment and avoids delaying the farming season due to the long time spent fixing or disassembling.

Detailed Implementation

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of the present invention, a soil amendment mixer for flue-cured tobacco planting is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3As shown, the soil improver mixer for flue-cured tobacco planting according to an embodiment of the present invention includes a mixing box body 1. A feeding bin 7 is installed through the upper surface of the mixing box body 1, and a discharge pipe 8 is installed through the lower surface of the mixing box body 1. An opening is opened through the side surface of the mixing box body 1, and a sealing cover 2 is installed at the opening. A connecting rod 3 is welded between two sealing covers 2. A crushing roller 4 is installed between two sealing covers 2 through a sealing bearing seat, and a stirring paddle 5 is installed between two sealing covers 2 through a sealing bearing seat. The ends of the crushing roller 4 and the stirring paddle 5 are respectively connected to a drive mechanism 6 through a coupling. The drive mechanism 6 consists of a reducer and a drive motor, and a reducer is installed at the output end of the drive motor.

[0020] In one embodiment, the crushing roller 4 and the stirring paddle 5 are mounted between two sealing covers 2 via sealed bearing seats, forming a "drawer-type assembly" that can be pulled out as a whole. When the equipment experiences malfunctions such as wear on the stirring paddle 5 or jamming of the crushing roller 4, it is not necessary to disassemble the entire mixing tank body 1; simply opening the sealing cover 2 and pulling out the assembly is sufficient to complete the component inspection or replacement. Compared to the traditional "complete disassembly" maintenance method of fixed mixers, this method can save a significant amount of maintenance time, and is especially suitable for the "tight agricultural schedule" of flue-cured tobacco planting, avoiding delays in soil improvement during the equipment repair window.

[0021] Specifically, a fixing column 13 is welded to the side surface of the mixing tank body 1, a damping spring 16 is sleeved on the surface of the fixing column 13, a fixing plate 14 is provided on the side surface of the damping spring 16, an eccentric wheel 15 is provided on one side of the fixing plate 14, and the eccentric wheel 15 is connected to the fixing column 13 through a rotating shaft, and a handle 17 is installed on the side surface of the eccentric wheel 15.

[0022] In one embodiment, when the stirring paddle 5 or the crushing roller 4 is to be inspected or replaced, only the handle 17 needs to be turned (without the need for wrenches, screwdrivers or other tools). The eccentric structure of the eccentric wheel 15 is used to loosen the fixing plate 14 so that the staff can inspect and maintain it, which greatly reduces the maintenance time of the equipment and avoids delaying the farming season due to the long time spent fixing or disassembling.

[0023] Specifically, the edge of the sealing cover 2 has a slot, and a sealing gasket 12 is embedded in the slot.

[0024] In one embodiment, the groove on the edge of the sealing cap 2 is inlaid with a sealing gasket 12, which can effectively prevent soil dust from overflowing or amendment from leaking during the mixing process, thus avoiding environmental pollution and reducing material loss.

[0025] Specifically, a handle 18 is welded to the side surface of the sealing cover 2, and a rubber sleeve is fitted on the surface of the handle 18.

[0026] In one embodiment, the rubber sleeve design on the surface of the handle 18 improves the operator's grip comfort.

[0027] Specifically, a support leg 9 is welded to the lower surface of the mixing tank body 1, a support leg 10 is welded to the side surface of a sealing cover 2, and a support wheel 11 is installed on the lower surface of the support pusher by bolts.

[0028] In one embodiment, the support legs 9 of the mixing tank body 1 can ensure the stability of the equipment when operating on flat ground, while the support legs 10 on the side surface of the sealing cover 2 cooperate with the support wheels 11 to make it easier to pull out the "drawer-type component".

[0029] Specifically, an integrated controller 19 is provided on the side surface of the sealing cover 2.

[0030] In one embodiment, the integrated controller 19 on the side surface of the sealing cover 2 can centrally control the drive motor speed and the equipment operating status.

[0031] Working principle: The equipment is equipped with two independent drive mechanisms 6, which are connected to the ends of the crushing roller 4 and the mixing paddle 5 respectively through couplings. After the drive motor starts, electrical energy is converted into mechanical energy. The speed is reduced by the reducer and the torque is increased, which finally drives the crushing roller 4 to rotate to break up soil clumps. The mixing paddle 5 stirs strongly at low speed. When maintenance is required, the operator turns the handle 17 at the eccentric wheel 15 to loosen the fixing plate 14, so that the mixing paddle 5 and crushing roller 4 and other structures can be pulled out from the mixing box body 1 for maintenance. Conversely, during installation, by turning the handle 17, the eccentric wheel 15 rotates around the axis of the fixing column 13, pressing against the fixing plate 14, thereby fixing the sealing plate and causing the sealing plate and the inner sealing gasket 12 to fit tightly against the opening on the side surface of the mixing box body 1, forming a closed mixing space.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
