[0002] Mixed soil substrates are artificially prepared soils commonly used in seedling cultivation and planting. The core principle is to compensate for the deficiencies of a single soil type by combining various materials, thus providing a better environment for plant growth. During seedling cultivation, the mixed soil substrate needs to be sieved using specialized screening equipment to separate the smaller soil particles for use.

[0003] According to the search, CN214515978U discloses an agricultural soil screening device. The screening device is based on a base plate, with support columns installed at the top of both ends of the base plate. A rectangular mounting frame is fixed at the top of the support columns. The mounting frame has movable grooves on opposite sides, with screws running through the grooves. One end of the screw extends out of the mounting frame and is fitted with a pulley. The pulley is a belt pulley connected to the other end by a belt. A handle is also installed on the side of the pulley facing the mounting frame. Mounting blocks matching the cross-sectional dimensions of the grooves are slidably installed in the movable grooves. The screws pass through the mounting blocks, and a screen frame is installed between the mounting blocks. A material blocking mechanism is provided inside the screen frame.

[0004] However, the above-mentioned agricultural soil screening device has two problems when in use. First, the screen does not have a vibration function, and the soil substrate passes through the screen by its own weight, resulting in low screening efficiency. Second, the screen inclination cannot be adjusted, and the impurities left on the screen need to be manually cleaned, which is not conducive to the concentration of impurities, and is time-consuming and labor-intensive, affecting the overall operation process. Utility Model Content

[0005] This utility model provides a soil screening device for vegetable seedling cultivation to solve the following problems mentioned in the background art: First, the screen does not have a vibration function, and the soil substrate passes through the screen only by its own weight, resulting in low screening efficiency; Second, the screen inclination cannot be adjusted, and the impurities left on the screen need to be manually cleaned, which is not conducive to the concentration of impurities, and is time-consuming and labor-intensive, affecting the overall operation process.

[0006] To address the existing problems, this utility model provides a soil screening device for vegetable seedling cultivation, including a frame. The frame has wheels rotatably connected to its bottom front and rear ends. A discharge hopper is fixedly connected inside the frame. A mounting frame is provided on the upper side of the frame. The front end of the mounting frame is hinged to the front upper part of the frame, and the middle rear end of the mounting frame is hinged to the upper end of a hydraulic cylinder. The lower end of the hydraulic cylinder is hinged to the middle rear end of the frame. A set of vibrating supports is installed on both sides of the mounting frame. A screen frame is connected to the upper end of the vibrating supports. A screen mesh is fixedly connected to the bottom of the screen frame. A slag discharge port is provided at the front end of the screen frame. A vibrating motor is installed in the middle of both sides of the screen frame.

[0007] Furthermore, a slag discharge hopper is fixedly connected below the slag discharge port and at the front end of the frame.

[0008] Furthermore, the bottom of the slag discharge hopper is sloped, and the lower end of the bottom surface of the slag discharge hopper extends to the side of the frame and is open.

[0009] Furthermore, the bottom surface of the discharge hopper is inclined, and the lower end of its bottom surface is located at the front end of the frame and is open.

[0010] Furthermore, a fixing lug is fixedly connected to the rear end of the frame, and a traction frame is hinged to the fixing lug.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up an installation frame, a vibration support, a vibration motor, a screen frame and a screen, and the vibration motors on both sides of the screen frame operate, and with the assistance of the vibration support, transmit the vibration force to the screen frame and the screen at the bottom, so that the soil substrate put into the screen frame is quickly separated under the action of vibration, thus overcoming the defect of existing devices that do not have vibration function.

[0013] 2. This utility model, by setting up a hydraulic cylinder, a mounting frame, a discharge hopper, and a slag discharge port at the front end of the screen frame, allows for adjustment of the mounting frame's tilt angle during operation via the extension and retraction of the hydraulic cylinder. The front end of the mounting frame is hinged to the machine frame, and the rear end of the mounting frame moves up and down with the extension and retraction of the hydraulic cylinder, thereby adjusting the tilt of the screen frame connected to the mounting frame via a vibration support to adapt to the screening requirements of different soil substrates. Simultaneously, during operation, impurities that cannot pass through the screen mesh move towards the slag discharge port at the front end of the screen frame under the combined action of vibration and the tilt angle of the screen frame, eventually falling into the slag discharge hopper at the front end of the machine frame and being discharged from its side opening along the inclined surface of the slag discharge hopper. The above-mentioned design overcomes the deficiency of the existing technology where the screen tilt angle is not adjustable. Attached Figure Description
