Description

Technical Field

[0001] This utility model relates to the field of fertilizer mixing technology, specifically a fertilizer mixing device for agricultural machinery planting and fertilization. Background Technology

[0002] A fertilizer mixing device is an agricultural machine that mixes different types of fertilizers in a certain proportion to meet the needs of crop growth. Common fertilizer mixing devices include stirring mixing devices and drum mixing devices. Stirring mixing devices consist of a stirring drum and stirring blades. A motor drives the stirring blades to rotate, causing the fertilizer to be stirred and tumbled inside the drum, thus achieving mixing. Stirring mixing devices are simple in structure, easy to operate, and suitable for small-scale fertilizer mixing. Drum mixing devices consist of a drum and a drive unit. The drum is placed at an angle, and the fertilizer enters from one end. As the drum rotates, the fertilizer is continuously tumbled and stirred inside, thus achieving mixing. This type of mixing device has good mixing effect and high production efficiency, making it suitable for large-scale fertilizer mixing.

[0003] Chinese Patent No. CN216125512U discloses a fertilizer mixing device for planting and fertilizing in agricultural machinery, including a base, with screws penetrating both sides of the outer wall of the base, nuts sleeved on the outer wall of the screws, and a disassembly mechanism welded to the top of the base; a sliding mechanism is installed on one side of the outer wall of the base, a rotating mechanism is installed on the top of the sliding mechanism, and a watering mechanism is installed on the top of the base.

[0004] This utility model seals the shell and sliding cover when closed, facilitating the mixing of fertilizer inside the shell. During discharge, the electric slider is activated to move the sliding cover upward to the appropriate position, allowing the inner liner to be disassembled and the fertilizer inside to be completely removed. Although this solves the problem of inconvenient discharge and increased work difficulty to some extent, the mixing structure of this device is relatively simple, resulting in low fertilizer mixing efficiency, which also reduces work efficiency. Therefore, a fertilizer mixing device for planting and fertilizing in agricultural machinery is proposed. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1 This embodiment of an agricultural machinery fertilizer mixing device for planting includes a support 1 and a mixing tank 2 fixed on the top of the support 1. The top of the mixing tank 2 is provided with a feeding component 3, and the inside of the mixing tank 2 is provided with a mixing component 4 for processing the feeding.

[0025] Please see Figures 1 to 3 In this embodiment, the mixing component 4 includes a fixed frame 41 fixedly installed on the inner side wall of the mixing tank 2. Four rotating rods 42 are rotatably connected to the bottom of the fixed frame 41. Spiral blades 43 for stirring materials are fixed to the outer side of the rotating rods 42. A fixed rod 44 is fixed to the center of the bottom of the fixed frame 41. A cover plate 45 is fixed to the bottom of the fixed rod 44. A dual-shaft motor 46 is fixed to the bottom of the mixing tank 2. The output shaft at the upper end of the dual-shaft motor 46 is connected to the rotating rods 42 through gears. A transmission block 47 is fixed to the bottom of the output shaft at the lower end of the dual-shaft motor 46. A transmission disk 48 is slidably connected to the outer side of the transmission block 47. A rotating disk 49 is fixed to the top of the transmission disk 48. An electric lifting rod 410 is fixed inside the bracket 1. A collar that wraps around the rotating disk 49 is fixed to the opposite side of the electric lifting rod 410.

[0026] In this embodiment, the fixing frame 41 has a cross structure, the top of the rotating rod 42 is rotatably connected to the fixing frame 41 and the bottom is inserted into the inside of the cover plate 45, and a driven gear is fixed at one end of the rotating rod 42 inside the cover plate 45. The output shaft at the top of the dual-axis motor 46 passes through the bottom wall of the mixing tank 2 to the inside of the cover plate 45.

[0027] In this embodiment, a drive gear for use with a driven gear is fixed outside the output shaft of the dual-shaft motor 46 located inside the cover plate 45. A circular support plate for receiving the mixed materials is fixed at the bottom of the cover plate 45. The inner bottom wall of the mixing tank 2 and the circular support plate form an annular discharge port. The rotating disk 49 is embedded inside the discharge port and is slidably connected to the mixing tank 2. The top of the rotating disk 49 is provided with several annularly distributed protrusions for assisting stirring.

[0028] The output shaft of the dual-axis motor 46 is inserted into the inside of the cover plate 45. At the same time, the drive gear drives the driven gear on the outside of the rotating rod 42 to rotate, so that the dual-axis motor 46 drives the spiral blades 43 to continuously stir and mix the material. The multiple spiral blades 43 cooperate with each other to quickly achieve uniform mixing of the material.

[0029] In this embodiment, the transmission block 47 has a cross-shaped structure, and the inside of the transmission disc 48 is fixed with a limiting disc by a connecting rod. The surface of the limiting disc is provided with a cross-shaped groove that is used in conjunction with the transmission block 47.

[0030] By setting a cross-shaped transmission block 47 in conjunction with a transmission disc 48, the transmission block 47 can drive the transmission disc 48 to rotate, while the transmission disc 48 can slide up and down on the outside of the transmission block 47. This allows the height of the rotating disc 49 to be changed, and the rotating disc 49 can rotate under the drive of the transmission disc 48 to stir the bottom of the material.

[0031] In this embodiment, an annular groove is provided on the outer side of the transmission disk 48, and the collar is embedded in the groove and slidably connected to the transmission disk 48. Lifting slots are provided on the sides of the bracket 1. The electric lifting rod 410 is located inside the lifting slot and a slider that is slidably connected to the lifting slot is fixed at the top. The collar is fixedly installed to the slider through a connecting rod.

[0032] It should be noted that the dual-axis motor 46 is fixed to the mixing tank 2 by means of a circular support plate, a cover plate 45, a fixing rod 44 and a fixing frame 41. At the same time, the collar and the electric lifting rod 410 limit the rotation of the lower output shaft of the dual-axis motor 46, thereby ensuring the stability of the dual-axis motor 46 during rotation.

[0033] Please see Figures 1 to 2 In this embodiment, the feeding assembly 3 includes a sealing cover 31 threadedly connected to the top of the mixing tank 2. A rotary motor 32 is fixed inside the sealing cover 31. A guide disc 33 fixedly installed on the side of the rotary motor 32 is provided with the sealing cover 31. A guide fan blade 34 is rotatably connected inside the guide disc 33. A guide hopper 35 fixedly installed on the sealing cover 31 is provided above the guide disc 33.

[0034] In this embodiment, the output shaft of the rotary motor 32 passes through the side wall of the guide disc 33 and is fixedly installed with the guide fan blade 34. The upper and lower sides of the guide disc 33 are provided with openings for feeding and discharging materials, and the bottom outlet of the guide hopper 35 is embedded inside the opening.

[0035] In this embodiment, all electrical components mentioned are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0036] The working principle of the above embodiments is as follows:

[0037] By pouring material into the guide disc 33 using the guide hopper 35, the rotary motor 32 is started, driving the guide fan blades 34 to tumble the material. The material passes through the guide disc 33 and enters the mixing tank 2. The dual-shaft motor 46 is started, driving the drive gear inside the cover plate 45 to rotate. The drive gear drives the rotating rod 42 to rotate through the driven gear, causing the rotating rod 42 to drive the spiral blades 43 to continuously stir the material inside the mixing tank 2. The electric lifting rod 410 is controlled to reciprocate up and down a certain distance, pushing the rotating disc 49 to change height. At the same time, the rotating disc 49 pushes the material inside the mixing tank 2. The material is changed and flipped, and the rotation of the dual-shaft motor 46 drives the transmission block 47 to rotate. The rotation of the transmission block 47 continuously drives the rotating disk 49 to rotate, so that the protrusion on the top of the rotating disk 49, together with the spiral blade 43, stirs the material and improves the mixing efficiency. By controlling the electric lifting rod 410 to drop sharply, the rotating disk 49 is completely removed from the bottom wall of the mixing tank 2. The circular tray and the inner wall of the mixing tank 2 form an annular opening, and the material is quickly discharged from the annular opening, realizing the rapid discharge of the mixture. This solves the problems of low mixing efficiency and inconvenient discharge of traditional fertilizer mixing devices.
