Description

Technical Field

[0001] This utility model application relates to the technical field of nutrient soil screening devices, specifically to a nutrient soil screening device. Background Technology

[0002] A nutrient soil screening device is a specialized mechanical device used to separate and classify soil particles of different sizes. Its core function is to effectively separate impurities, large particles, and fine particles from the nutrient soil through vibration or rotation. This device typically employs a multi-layer screen design, with screen specifications adjustable to achieve precise screening. The screening device mainly relies on the power generated by a vibrating motor or rotating drum to create a throwing motion of the soil on the screen surface, thereby accelerating the screening process. Nutrient soil screening devices are widely used in agriculture, environmental science, soil science, and other fields.

[0003] Chinese patent CN221753489U discloses a nutrient soil screening device, including a screening box and a heating device fixedly embedded on one side of the screening box near the top. A blower is fixedly embedded on the other side of the screening box near the top. The nutrient soil screening device heats the interior of the screening box by activating the heating device, and simultaneously blows air into the interior of the screening box by activating the blower, thus drying the nutrient soil. Simultaneously, a vibration motor and a servo motor are activated, and with the threaded strip and two medium-sized sliders fixedly connected and guided by the medium-sized sliding grooves, the moisture content of the nutrient soil is reduced, preventing clumping. A pressure roller then crushes the clumped nutrient soil, providing a double protection and preventing waste of nutrient soil clumps.

[0004] The nutrient soil screening device described in the aforementioned patent document uses a vibrating motor to drive a screen plate to vibrate at a fixed frequency, thereby screening the material. While existing nutrient soil screening devices can achieve material screening, the vibration frequency of the screen plate cannot be adjusted, making them extremely inconvenient to use. Therefore, a nutrient soil screening device is proposed. Utility Model Content

[0005] To address the aforementioned problems, a nutrient soil screening device is provided. A servo motor drives a pendulum to rotate. Simultaneously, the pendulum's rotation drives a connecting rod via a slider, which in turn drives a screen disc via a hinged seat, causing the screen disc to vibrate. When the pendulum rotates, it moves the threaded slider within a second limiting groove, thereby adjusting the distance between the slider and the central shaft of the servo motor. By adjusting the distance between the slider and the servo motor's central shaft, the vibration amplitude of the screening mechanism driven by the drive mechanism is controlled. This solves the problem of the inability to adjust the vibration amplitude of the screening device.

[0006] To address the problems of the prior art, this application provides a nutrient soil screening device, including a base, a screening mechanism capable of screening materials on the top of the base, a driving mechanism capable of driving the screening mechanism installed on one side of the top of the base, and a reset mechanism for resetting the screening mechanism installed on the top of the base. The screening mechanism includes a screen plate suspended on the top of the base.

[0007] The drive mechanism includes a servo motor, the output end of which is fixed with a pendulum, a second limiting groove is longitudinally provided on the pendulum, and a rotatable threaded rod is horizontally installed in the second limiting groove.

[0008] The drive mechanism also includes a slider mounted on a threaded rod, a mounting post fixed to the top of the slider, the slider being threadedly engaged with the threaded rod, and a connecting rod provided at the top of the slider, one end of which is hinged to the mounting post at the top of the slider.

[0009] A hinge seat is fixed on the outer wall of the sieve disc, and the end of the connecting rod away from the slider is hinged to the mounting column on one side of the hinge seat.

[0010] As one technical solution of this application, a plurality of second mounting rods are fixed at equal intervals around the central axis on the outer wall of the sieve disc;

[0011] The reset mechanism includes a fixed seat symmetrically fixed to the top of the base, a first mounting rod symmetrically fixed to the top of the first limiting groove and installed longitudinally, a tension spring being fitted on the first mounting rod, and the end of the tension spring away from the first mounting rod being fitted on the second mounting rod.

[0012] As one technical solution of this application, a first limiting groove is horizontally provided on the fixed base;

[0013] Several support rods that can pass through the first limiting groove are horizontally fixed on both sides of the sieve plate, and the support rods are fitted with rotatable sleeves.

[0014] As one technical solution of this application, one end of the support rod is fixed with an anti-detachment plate, which is used to prevent the support rod from falling out of the first limiting groove.

[0015] As one technical solution of this application, the base includes a support frame, and a guide tube is longitudinally fixed on the upper end surface of the support frame;

[0016] The base also includes a lifting frame, and a rod is longitudinally provided at the bottom of the lifting frame. The rod is installed longitudinally.

[0017] A hydraulic telescopic component for driving the longitudinal movement of the lifting frame is fixed on one side of the guide tube, and the telescopic end of the hydraulic telescopic component is fixedly connected to the lifting frame.

[0018] As one technical solution of this application, the bottom of the screen is provided with a guide hood for discharging materials, and the top of the guide hood is fixed on the lifting frame.

[0019] The advantages of this utility model application compared to the prior art are:

[0020] This application utilizes a servo motor to drive a pendulum to rotate. Simultaneously, the pendulum's rotation drives a connecting rod via a slider, which in turn drives a screen plate via a hinged seat, causing the screen plate to vibrate. When the pendulum rotates, it causes the threaded slider to move within a second limiting groove, thereby adjusting the distance between the slider and the central shaft of the servo motor. By adjusting the distance between the slider and the central shaft of the servo motor, the vibration amplitude of the drive mechanism driving the screening mechanism is controlled. This solves the problem of the inability to adjust the vibration amplitude of the screening device. Attached Figure Description

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] See Figures 1-6 As shown, a nutrient soil screening device includes a base 1, a screening mechanism 4 capable of screening materials is provided on the top of the base 1, a driving mechanism 5 capable of driving the screening mechanism 4 is installed on one side of the top of the base 1, and a reset mechanism 2 for resetting the screening mechanism 4 is installed on the top of the base 1. The screening mechanism 4 includes a screen plate 41 suspended on the top of the base 1.

[0030] The drive mechanism 5 includes a servo motor 51, and a pendulum 52 is fixed at the output end of the servo motor 51. A second limiting groove 521 is longitudinally opened on the pendulum 52, and a rotatable threaded rod 53 is horizontally installed in the second limiting groove 521.

[0031] The drive mechanism 5 also includes a slider 54 mounted on the threaded rod 53. A mounting post is fixed on the top of the slider 54. The slider 54 is threadedly engaged with the threaded rod 53. A connecting rod 56 is provided on the top of the slider 54. One end of the connecting rod 56 is hinged to the mounting post on the top of the slider 54.

[0032] A hinge seat 57 is fixed on the outer wall of the screen plate 41, and the end of the connecting rod 56 away from the slider 54 is hinged to the mounting column on one side of the hinge seat 57.

[0033] When the servo motor 51 starts, it drives the pendulum 52 to rotate. Simultaneously, the pendulum 52 rotates, driving the connecting rod 56 via the slider 54. The connecting rod 56 then drives the screen plate 41 via the hinge seat 57, causing the screen plate 41 to vibrate. As the pendulum 52 rotates, it drives the threaded slider 54 to move within the second limiting groove 521, thereby adjusting the distance between the slider 54 and the central axis of the servo motor 51. By adjusting the distance between the slider 54 and the central axis of the servo motor 51, the vibration amplitude of the drive mechanism 5 driving the screening mechanism 4 is adjusted. This solves the problem of the inability to adjust the vibration amplitude of the screening device.

[0034] See Figure 3 and Figure 6 As shown, several second mounting rods 45 are fixed at equal intervals around the central axis on the outer wall of the sieve plate 41.

[0035] The reset mechanism 2 includes a fixed seat 20 symmetrically fixed to the top of the base 1, a first mounting rod 22 longitudinally fixed to the top of the first limiting groove 21, a tension spring 23 fitted on the first mounting rod 22, and the end of the tension spring 23 away from the first mounting rod 22 fitted on the second mounting rod 45.

[0036] The two ends of the tension spring 23 are respectively sleeved on the first mounting rod 22 and the second mounting rod 45. The spring tension of the tension spring 23 acts on the screen plate 41 through the second mounting rod 45, so that the screen plate 41 can return to its initial position when screening stops.

[0037] See Figure 3 and Figure 6 As shown, a first limiting groove 21 is horizontally provided on the fixed base 20;

[0038] Several support rods 42 that can pass through the first limiting groove 21 are horizontally fixed on both sides of the sieve plate 41, and the support rods 42 are fitted with rotatable sleeves 43.

[0039] By symmetrically fixing multiple support rods 42 through the first limiting groove 21 on both sides of the screen plate 41, and then fitting sleeves 43 around the outside of the support rods 42, the support rods 42 can support the screen plate 41 through the sleeves 43, thereby increasing the load on the screen plate 41. When the screen plate 41 moves, it can drive the support rods 42 to move synchronously. At the same time, the support rods 42 will drive the sleeves 43 to travel along the first limiting groove 21. At this time, the sleeves 43 will rotate around the central axis of the support rods 42, and the rotation of the sleeves 43 will reduce the wear between the sleeves 43 and the first limiting groove 21.

[0040] See Figure 3 and Figure 6 As shown, one end of the support rod 42 is fixed with an anti-detachment plate 44, which is used to prevent the support rod 42 from falling out of the first limiting groove 21.

[0041] By fixing the anti-detachment plate 44 to one end of the support rod 42, the anti-detachment plate 44 can effectively prevent the support rod 42 from falling out of the first limiting groove 21. At the same time, the anti-detachment plate 44 can also effectively prevent the sleeve 43 from displacing along the central axis of the support rod 42, thereby ensuring the stability of the sleeve 43.

[0042] See Figure 2 As shown, the base 1 includes a support frame 11, and a guide tube is longitudinally fixed on the upper end surface of the support frame 11;

[0043] The base 1 also includes a lifting frame 12, and the bottom of the lifting frame 12 is provided with a vertically inserted rod, which is installed vertically.

[0044] A hydraulic telescopic component 13 for driving the longitudinal movement of the lifting frame 12 is fixed on one side of the guide tube, and the telescopic end of the hydraulic telescopic component 13 is fixedly connected to the lifting frame 12.

[0045] When the hydraulic telescopic component 13 is activated, it drives the lifting frame 12 to move longitudinally, thereby adjusting the overall height of the base 1. To ensure the stability of the lifting frame 12, a rod is longitudinally fixed at the bottom of the lifting frame 12 and then installed inside the guide tube. As the lifting frame 12 moves longitudinally, the rod moves longitudinally along the guide tube. The cooperation between the rod and the guide tube limits the movement of the lifting frame 12, effectively ensuring its stability.

[0046] See Figure 2 As shown, the bottom of the screen plate 41 is provided with a guide hood 3 for discharging materials, and the top of the guide hood 3 is fixed on the lifting frame 12.

[0047] When the screen plate 41 screens the material, the screened material falls into the inside of the guide hood 3, and then the material falls naturally along the inner wall of the guide hood 3, thereby realizing automatic material discharge.

[0048] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
