Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, specifically to a device for automatically preparing a complete nutrient solution during tomato planting. Background Technology

[0002] In modern tomato cultivation, especially in soilless cultivation within protected agriculture, the nutrients required for tomato growth mainly rely on artificially prepared complete nutrient solutions. The quality and efficiency of the complete nutrient solution preparation directly affect the growth status, yield, and quality of tomatoes. Therefore, efficient and precise nutrient solution preparation equipment has become one of the key pieces of equipment in the tomato cultivation process.

[0003] Currently, most devices on the market for preparing tomato nutrient solutions rely solely on a single stirring mechanism to mix the nutrient solution ingredients. This one-way stirring leads to uneven mixing of the ingredients, resulting in localized areas of excessively high or low concentrations. This affects the overall quality of the nutrient solution and consequently has an adverse impact on tomato growth. Furthermore, the preparation tanks are often fixed in place, limiting the flow range of the ingredients within the tank during stirring, further exacerbating the problem of uneven mixing. This also hinders the full contact and reaction of the ingredients in different areas of the tank. Therefore, there is an urgent need for an automatic tomato nutrient solution preparation device that can achieve thorough mixing of the ingredients. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tomato nutrient solution preparation device to solve the problem of uneven mixing in existing tomato nutrient solution preparation devices, so as to achieve full mixing of nutrient solution raw materials and improve preparation quality and efficiency.

[0005] To achieve the above objectives, this utility model provides an automatic tomato nutrient solution preparation device, including a U-shaped support, a linear reciprocating mechanism and a guiding mechanism on the U-shaped support, a preparation tank on the guiding mechanism, and a forward stirring mechanism and a reverse stirring mechanism on the preparation tank.

[0006] The linear reciprocating mechanism includes a geared motor fixed on a U-shaped support. The output shaft of the geared motor passes through the U-shaped support and is fixed to a crank. A connecting rod is movably mounted on the other end of the crank. The guiding mechanism includes a pair of guide rails fixed on the U-shaped support. Guide blocks that can slide left and right are engaged on the guide rails. T-shaped supports are fixed on the two guide blocks. A mixing tank is fixed on the T-shaped supports. The end of the connecting rod away from the crank is movably connected to the T-shaped support via a pin, and a wear-resistant copper sleeve is fitted at the connection between the pin and the T-shaped support.

[0007] The forward stirring mechanism includes a forward-rotating motor fixed to the top of the preparation tank. The output shaft of the forward-rotating motor extends into the preparation tank and is fixed to a forward-rotating stirring shaft. At least two sets of forward-rotating stirring blades are evenly arranged on the side wall of the forward-rotating stirring shaft. The reverse stirring mechanism includes a reverse-rotating motor fixed to the top of the preparation tank and located on one side of the forward-rotating motor. The output shaft of the reverse-rotating motor extends into the preparation tank and is fixed to a reverse-rotating stirring shaft. At least two sets of reverse-rotating stirring blades are evenly arranged on the side wall of the reverse-rotating stirring shaft.

[0008] Both ends of the guide rail are fixed with limit blocks, and rubber buffer pads are attached to the side of the limit blocks closest to the guide blocks. The top of the preparation tank is provided with at least two feed ports, each of which is threaded with a sealing cap, and the inner wall of the sealing cap is provided with a silicone sealing ring. The side wall of the preparation tank is provided with a discharge pipe, and an electromagnetic control valve is connected in series on the discharge pipe. The electromagnetic control valve is electrically connected to an external controller.

[0009] According to the formula requirements of the tomato nutrient solution, the staff added different types of nutrient solution ingredients into the preparation tank through multiple inlets on the top of the tank. Each inlet is threaded with a sealing cap with a silicone sealing ring. After the ingredients are added, the staff can tighten the cap. The silicone sealing ring effectively prevents the ingredients or nutrient solution from overflowing from the inlet during preparation, while also preventing external impurities from entering the tank, thus ensuring the purity of the nutrient solution.

[0010] After the device is started, the forward and reverse stirring mechanisms begin working simultaneously: the forward motor drives the forward stirring shaft and its blades to rotate clockwise, while the reverse motor drives the reverse stirring shaft and its blades to rotate counterclockwise. Because the forward and reverse stirring blades rotate in opposite directions, a bidirectional stirring flow field is formed inside the mixing tank. This interaction of the two flow fields breaks the stable flow state created by a single stirring direction, causing the nutrient solution materials inside the tank to undergo intense relative motion. This significantly increases the contact area and collision frequency between different materials, effectively avoiding the problem of uneven mixing caused by a single stirring direction.

[0011] While the forward and reverse stirring mechanisms are operating, the linear reciprocating mechanism also starts simultaneously: the geared motor drives the crank to rotate around the output shaft of the geared motor in a circular motion. Since the other end of the crank is movably connected to the connecting rod, and the end of the connecting rod away from the crank is movably connected to the T-shaped support through a pin, the circular motion of the crank is converted into the linear reciprocating motion of the T-shaped support through the connecting rod. Furthermore, because the T-shaped support is engaged with the guide rail through the guide block, and the guide rail guides the sliding direction of the guide block, the T-shaped support can drive the mixing tank to make a stable left-right linear reciprocating motion along the length of the guide rail.

[0012] The reciprocating motion of the mixing tank and the bidirectional stirring motion inside work together. On the one hand, the reciprocating motion of the mixing tank drives the raw materials inside the tank to move horizontally, expanding the range of movement of the raw materials and allowing the raw materials in different areas of the tank to flow and mix more fully. On the other hand, the bidirectional stirring motion further refines the mixing of the raw materials during the movement. The synergistic effect of the two significantly improves the uniformity of the mixing of the raw materials, ensuring that the concentration of the prepared tomato nutrient solution is consistent in all areas, meeting the nutrient requirements for tomato growth.

[0013] During the reciprocating sliding of the mixing tank along the guide rail by the T-shaped support, the limiting blocks at both ends of the guide rail limit the sliding stroke of the guide block, preventing it from slipping off the guide rail due to excessive sliding and ensuring the stability of the device operation. Simultaneously, the rubber buffer pads attached to the side of the limiting blocks near the guide blocks provide cushioning and shock absorption when the guide blocks slide to the ends of the guide rail and contact the limiting blocks, avoiding rigid collisions between the guide blocks and the limiting blocks, reducing component wear, and extending the service life of both the guide blocks and the limiting blocks.

[0014] In addition, the wear-resistant copper sleeve fitted at the connection between the pin and the T-shaped support can reduce the coefficient of friction between the pin and the T-shaped support, reduce wear during relative motion, further improve the operational stability and service life of the linear reciprocating mechanism, and ensure that the mixing tank can perform reciprocating motion stably for a long time.

[0015] Beneficial effects This invention creates a bidirectional stirring flow field by setting up a forward stirring mechanism and a reverse stirring mechanism. At the same time, it works in conjunction with a linear reciprocating mechanism to drive the preparation tank to reciprocate left and right. The bidirectional stirring and the reciprocating motion of the tank work together to greatly increase the contact area and movement range of the raw materials, effectively solving the problem of uneven mixing in existing devices. This ensures that the concentration of the prepared tomato nutrient solution is consistent in all areas, improves the quality of the nutrient solution, and provides a guarantee for the healthy growth of tomatoes.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown; An automatic tomato nutrient solution preparation device.

[0019] In this implementation plan: To address the technical problems existing in the prior art, as disclosed in the background art above, "Currently, most devices on the market for preparing tomato nutrient solution rely solely on a single stirring mechanism to mix the nutrient solution raw materials. The stirring direction is singular, leading to uneven mixing of the raw materials and the tendency for local concentrations to be too high or too low, affecting the overall quality of the nutrient solution and thus adversely impacting tomato growth. The preparation tanks are mostly fixed, and during the stirring process, the flow range of the raw materials within the tank is limited, further exacerbating the problem of uneven mixing and also hindering the full contact and reaction of the raw materials in different areas of the tank." In practical terms, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, an automatic tomato nutrient solution preparation device is provided.

[0020] Example 1 This embodiment provides an automatic tomato nutrient solution preparation device, such as... Figure 1-4 As shown, it includes a U-shaped support 1, a linear reciprocating mechanism 2 and a guide mechanism 3 on the U-shaped support 1, a preparation tank 4 on the guide mechanism 3, and a forward stirring mechanism 5 and a reverse stirring mechanism 6 on the preparation tank 4.

[0021] The linear reciprocating mechanism 2 includes a geared motor 21 bolted to a U-shaped support 1. The geared motor 21 is model GF1-50-60S. The output shaft of the geared motor 21 passes through the U-shaped support 1 and is fixed to a crank 22 via a flat key. The other end of the crank 22 is movably connected to a connecting rod 23 via a pin. The guiding mechanism 3 includes a pair of guide rails 31 welded to the U-shaped support 1. The guide rails 31 have an "I" shaped cross section. Guide blocks 32 that can slide left and right are engaged on the guide rails 31. The guide blocks 32 have grooves that match the guide rails 31. T-shaped supports 33 are bolted to the two guide blocks 32. A preparation tank 4 is welded to the T-shaped supports 33. The end of the connecting rod 23 away from the crank 22 is movably connected to the T-shaped support 33 via a pin, and a wear-resistant copper sleeve 14 is fitted at the connection between the pin and the T-shaped support 33.

[0022] The forward stirring mechanism 5 includes a forward-rotating motor (model Y2-0L-4) bolted to the top of the preparation tank 4. The output shaft of the forward-rotating motor extends into the preparation tank 4 via a coupling and is fixed to a forward-rotating stirring shaft. Three sets of forward-rotating stirring blades, spirally shaped, are evenly welded to the side wall of the stirring shaft to enhance the stirring effect. The reverse stirring mechanism 6 includes a reverse-rotating motor (model Y2-0L-4) bolted to the top of the preparation tank 4 and located on one side of the forward-rotating motor. The output shaft of the reverse-rotating motor extends into the preparation tank 4 via a coupling and is fixed to a reverse-rotating stirring shaft. Three sets of reverse-rotating stirring blades, also spirally shaped, are evenly welded to the side wall of the reverse-rotating stirring shaft, with the spiral directions of the forward and reverse stirring blades opposite.

[0023] Both ends of the guide rail 31 are fixed with limit blocks by bolts. The limit blocks are made of 45# steel. A rubber buffer pad with a thickness of 5mm is attached to the side of the limit block near the guide block 32 with strong adhesive to provide good cushioning. The top of the preparation tank 4 is provided with three feed ports, which are used to add different types of nutrient solution raw materials. Each feed port is threaded with a sealing cap. The inner wall of the sealing cap is fixed with a silicone sealing ring through a groove. The silicone sealing ring has a circular cross-section to ensure the sealing performance of the feed port.

[0024] The bottom of the side wall of the preparation tank 4 is fixed with a discharge pipe by welding. The discharge pipe is made of stainless steel and is connected in series with an electromagnetic control valve. The electromagnetic control valve is model 2W-160-15. The electromagnetic control valve is electrically connected to an external controller through a wire. The operator can remotely control the opening and closing of the electromagnetic control valve through the external controller.

[0025] The operating steps of the automatic tomato nutrient solution preparation device in this embodiment are as follows: The first step is to add raw materials: According to the formula of the tomato nutrient solution, the staff adds nitrogen source raw materials, phosphorus source raw materials, potassium source raw materials and other trace element raw materials into the preparation tank 4 through the three feed ports on the top of the preparation tank 4. After the addition is completed, the sealing cap at each feed port is tightened. The silicone sealing ring on the inner wall of the sealing cap is used to seal the feed port to prevent raw materials from overflowing or impurities from entering.

[0026] The second step is to start the device: the geared motor 21, the forward motor and the reverse motor are started by the external controller. The forward motor drives the forward stirring shaft and the forward stirring blade to rotate clockwise, and the reverse motor drives the reverse stirring shaft and the reverse stirring blade to rotate counterclockwise. At the same time, the geared motor 21 drives the crank 22 to make circular motion. The crank 22 drives the T-shaped support 33 to make left and right linear reciprocating motion along the guide rail 31 through the connecting rod 23. The T-shaped support 33 then drives the preparation tank 4 to make left and right reciprocating motion synchronously.

[0027] The third step is mixing and preparation: Under the bidirectional mixing of the forward and reverse mixing mechanism and the reciprocating motion of the preparation tank 4, the various nutrient solution raw materials in the preparation tank 4 are fully mixed. The mixing time is set to 30 minutes according to the nutrient solution formula requirements to ensure that the raw materials are mixed evenly and form a complete nutrient solution that meets the growth needs of tomatoes.

[0028] The fourth step is the nutrient solution discharge: After the mixing and preparation are completed, the staff sends an opening signal to the electromagnetic control valve through the external controller. The electromagnetic control valve opens, and the prepared tomato nutrient solution is discharged through the discharge pipe. It can be directly connected to the pipeline to be transported to the tomato planting area for irrigation, or transported to the storage tank for storage.

[0029] Step 5: Shutdown of the device: After the nutrient solution is discharged, the staff closes the electromagnetic control valve through the external controller, and at the same time shuts down the geared motor 21, the forward motor and the reverse motor, thus completing the preparation of one batch of tomato nutrient solution. If the next batch needs to be prepared, the above steps can be repeated.

[0030] The automatic tomato nutrient solution preparation device of this embodiment effectively solves the problems of uneven mixing, complicated operation and short service life of existing devices through reasonable structural design. It can realize the efficient and accurate preparation of tomato nutrient solution and meet the needs of modern tomato cultivation.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
