Description

Technical Field

[0001] This utility model belongs to the field of planting soil preparation technology, specifically relating to a planting soil preparation device with automatic weighing and preparation. Background Technology

[0002] In fields such as horticulture and agricultural planting, the accuracy of the soil formulation plays a crucial role in plant growth and development. To meet this need, soil mixing devices with automatic weighing and dispensing functions have emerged. These devices can weigh various raw materials with relatively high accuracy and complete the mixing process according to the preset formula, greatly improving the efficiency and accuracy of soil mixing. This represents a significant improvement over traditional manual mixing methods.

[0003] However, current devices have a significant drawback: when weighing raw materials, if the weight of the input material exceeds the preset value, it is inconvenient to remove the excess material. In actual production, due to limitations in the control precision of the feeding equipment and differences in material flowability, it is difficult to achieve accurate feeding at one time, often resulting in raw material weight being too high. Once this happens, existing devices often lack an effective handling mechanism, and operators usually have to manually remove the excess material. The operation process is cumbersome, consumes a lot of time and manpower, seriously affects the efficiency of batching, and it is difficult to ensure the consistency of the amount removed each time during manual removal, which can easily introduce new errors and affect the accuracy of the final planting soil formula.

[0004] To address this problem, this utility model proposes an innovative solution. Utility Model Content

[0005] The purpose of this invention is to provide a planting soil mixing device with automatic weighing and mixing, which can collect and pre-store heavier raw materials. When weighing and mixing again later, if the amount of the raw material added is insufficient, the pre-stored raw material will be used first.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A planting soil batching device with automatic weighing and batching includes a mixing chamber, and multiple feeding structures are installed on the outer side of the mixing chamber and near the top.

[0008] Each of the feeding structures includes a feeding pipe, and a guide pipe is fixed to one end of the feeding pipe near the mixing chamber. The guide pipe is located near the bottom of the feeding pipe and is inclined. The end of the guide pipe away from the feeding pipe is fixed to the mixing chamber.

[0009] A weighing sensor is installed at the bottom of the inner side of the feed pipe. A baffle is slidably connected to the inner side of the feed pipe. The baffle is located on the side of the weighing sensor near the guide tube and is fitted to the weighing sensor. A first electric push rod is installed on the feed pipe, and the stroke rod of the first electric push rod is connected to the baffle.

[0010] A collection structure is installed on the side of the feed pipe away from the mixing chamber, and a guide structure is installed on the weighing sensor.

[0011] The collection structure includes a collection chamber fixed to one side of the feed pipe, and the inner cavity of the collection chamber is in communication with the inner cavity of the feed pipe. A second electric push rod is installed in the collection chamber. A push plate is fixed to the end of the stroke rod of the second electric push rod facing the feed pipe, and the push plate is in close contact with the collection chamber. A material guiding structure is installed in the collection chamber near the feed pipe.

[0012] The material guiding structure includes a rotating column rotatably connected inside the collection bin. Both ends of the rotating column are fitted into the collection bin. Collection grooves are evenly distributed on the outer side of the rotating column. The top and bottom of the rotating column are fitted into the collection bin on a straight line with the center. A second motor is installed on the collection bin, and the output end of the second motor passes through the collection bin and is connected to the rotating column.

[0013] A notch is formed between the upper part of the rotating column near the feed pipe and the collection bin. An air blowing duct is installed in the notch, and multiple connecting pipes are connected to the top of the air blowing duct.

[0014] The collection chamber is set at a downward angle relative to the feed pipe.

[0015] The guide structure includes a guide ramp, which is mounted on the top of the weighing sensor and is inclined toward the direction of the guide tube.

[0016] A first motor is installed inside the feed pipe and at the bottom of the guide plate. A cam is fixed to the output end of the first motor, and the cam abuts against the guide plate.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention, through the setting of a rotating column, can guide raw materials and pre-store them through a collection bin. This allows for the collection and pre-storage of heavier raw materials. When weighing and batching again later, if the amount of the raw material added is insufficient, the device can prioritize the use of the pre-stored raw materials. This not only solves the problem of inconvenient handling of excess raw materials but also realizes the recycling of raw materials, further improving the intelligence and efficiency of the batching process and bringing a new technological breakthrough to the field of planting soil batching devices.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-5 As shown, a planting soil batching device with automatic weighing and batching includes a mixing chamber 1. Multiple feeding structures are installed on the outside of the mixing chamber 1 and near the top. The multiple feeding structures feed the planting soil ingredients, such as peat, perlite, coconut coir, organic fertilizer, etc.

[0028] Each feeding structure includes a feeding pipe 2. A guide pipe 4 is fixed to one end of the feeding pipe 2 near the mixing chamber 1. The guide pipe 4 is located near the bottom of the feeding pipe 2 and is inclined. The end of the guide pipe 4 away from the feeding pipe 2 is fixed to the mixing chamber 1. A weighing sensor 3 is installed at the bottom inside the feeding pipe 2. The weighing sensor 3 ensures that when the raw material is fed from the feeding pipe 2, it falls onto the weighing sensor 3 and is weighed by the weighing sensor 3.

[0029] A baffle 6 is slidably connected to the inner side of the feed pipe 2. The feed pipe 2 is provided with a groove corresponding to the baffle 6. The baffle 6 is located on the side of the weighing sensor 3 near the guide pipe 4, and the baffle 6 is fitted to the weighing sensor 3. This arrangement prevents the raw material from falling into the gap between the weighing sensor 3 and the baffle 6. A first electric push rod 5 is installed on the feed pipe 2. The stroke rod of the first electric push rod 5 is connected to the baffle 6. After the weighing sensor 3 finishes weighing the raw material, the first electric push rod 5 can be activated, so that the stroke rod of the first electric push rod 5 drives the baffle 6 to move upward, thereby allowing the raw material to enter from the feed pipe 2 to the guide pipe 4, and then enter the mixing chamber 1 through the guide pipe 4. The mixing structure in the mixing chamber 1 will then mix the raw material.

[0030] A guide structure is installed on the load cell 3;

[0031] Furthermore, the guiding structure includes a guide ramp 7, which is mounted on top of the weighing sensor 3 and is inclined towards the guide tube 4. The guide ramp 7 guides the raw material, ensuring it enters the guide tube 4 and is then guided into the mixing chamber 1. A first motor 8 is installed inside the feed pipe 2 and at the bottom of the guide ramp 7. Both the second motor 15 and the first motor 8 are fitted with protective shells to protect them. The output end of the first motor 8 is fixed... A cam 9 is fixed, and the cam 9 abuts against the guide ramp 7. By driving the first motor 8, the output end of the first motor 8 drives the cam 9 to rotate, so that the cam 9 can reciprocate to strike the guide ramp 7 when rotating, so that the guide ramp 7 will vibrate. This can vibrate the residual material on the guide ramp 7 and make it fall off. When the weighing sensor 3 weighs the material, it can first remove the weight of the guide ramp 7, that is, tare. And control the protrusion on the cam 9 to be at the bottom to avoid the guide ramp 7 supporting the weighing sensor 3, which would lead to inaccurate weighing.

[0032] A collection structure is installed on the side of the feed pipe 2 away from the mixing chamber 1.

[0033] See attached document Figure 3 and attached Figure 5The collection structure includes a collection chamber 10 fixed to one side of the feed pipe 2, and the inner cavity of the collection chamber 10 is connected to the inner cavity of the feed pipe 2. Generally, a large amount of raw material enters the feed pipe 2, and the collection chamber 10 is located above the weighing sensor 3, so that the raw material can enter the collection chamber 10. A second electric push rod 11 is installed in the collection chamber 10. A push plate 12 is fixed to the end of the stroke rod of the second electric push rod 11 that faces the feed pipe 2, and the push plate 12 and the collection chamber 10 fit together to prevent the raw material from entering the gap between the push plate 12 and the collection chamber 10. A material guiding structure is installed in the collection chamber 10 and near the feed pipe 2.

[0034] When the weighing sensor 3 weighs the raw materials, if there is a slight excess due to the rapid feeding, the excess raw materials can be poured into the collection bin 10 through the material guiding structure. When the weighing sensor 3 weighs to a suitable threshold, the raw materials can be introduced into the mixing bin 1. When the raw materials are less than the threshold, the second electric push rod 11 is activated, causing the push plate 12 to push the pre-stored raw materials in the collection bin 10 to contact the material guiding structure. The material guiding structure then introduces the raw materials into the feed pipe 2. After the weight of the raw materials in the feed pipe 2 is appropriate, the raw materials are introduced into the mixing bin 1. This allows the collection bin 10 to pre-store excess raw materials. When the raw materials in the feed pipe 2 are less, the raw materials in the collection bin 10 can be used first, thus enabling the collection bin 10 to achieve a dynamic compensation effect.

[0035] See attached document Figure 5 The material guiding structure includes a rotating column 13 rotatably connected inside the collection bin 10. The two ends of the rotating column 13 are fitted with the collection bin 10 to prevent raw materials from entering the gap between the rotating column 13 and the collection bin 10. Collection grooves 14 are evenly arranged on the outer side of the rotating column 13. The top and bottom of the rotating column 13 are fitted with the collection bin 10 on a straight line with the center. This allows the collection bin 10 to scrape off excess raw materials when the collection grooves 14 guide the raw materials, so that only about the same weight of raw materials can be transported in the collection grooves 14 at a time. A second motor 15 is installed on the collection bin 10, and the output end of the second motor 15 passes through the collection bin 10 and is connected to the rotating column 13.

[0036] The second motor 15 is driven so that the output end of the second motor 15 drives the rotating column 13 to rotate, and the rotating column 13 drives the collecting groove 14 to rotate. When there is a lot of raw material in the feed pipe 2, the rotating column 13 can be rotated so that the collecting groove 14 on the rotating column 13 digs up the raw material and then rotates into the collecting bin 10. The collecting bin 10 is set in a downward inclined state relative to the feed pipe 2 so that the raw material falls into the collecting bin 10 and avoids contact with the rotating column 13.

[0037] If there is little raw material in the feed pipe 2, the second electric push rod 11 can be driven, causing the stroke rod of the second electric push rod 11 to move the push plate 12, so that the push plate 12 can pour the raw material into the rotating column 13 and then drive the collection groove 14 to rotate, pouring the raw material in the collection bin 10 into the feed pipe 2. When the rotating column 13 rotates, a notch is formed between the upper part of the rotating column 13 near the feed pipe 2 and the collection bin 10. A blowing duct 16 is installed in the notch, and the top of the blowing duct 16 is connected to multiple connecting pipes 17. When the collection groove 14 digs out the raw material in the feed pipe 2 at this time, the setting of the blowing duct 16 allows the external fan to guide the air force through the connecting pipes 17 into the blowing duct 16, thereby blowing away the raw material at the position of the collection groove 14.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
