Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a fertilizer screening machine. Background Technique

[0002] After production, the sizes of fertilizer particles are different, and the fertilizer needs to be screened. However, during the screening process, larger particles or impurities are likely to block the sieve holes, affecting the screening efficiency.

The lower surface of the fixing plate is fixedly connected with side plates, and the side plates are inclined. A receiving plate and a sieve plate are fixedly connected between the two side plates, and the side surface of the receiving plate is fixedly connected with the side surface of the sieve plate. The other side surface of the sieve plate is fixedly connected with a discharge frame, and the side surface of the discharge frame is simultaneously fixedly connected with the lower side surface of the side plate. L-shaped rotating plates are rotatably connected to both opposite outer sides of the discharge frame. One end of the L-shaped rotating plate is fixedly connected with a cover frame, and an observation window is opened on the cover frame. Magnetic strips are fixedly connected to the upper sides of the opposite inner sides of the two side plates. A vibration motor is installed on the lower surface of the receiving plate, and the output end of the vibration motor is in contact with the sieve plate. Support plates are fixedly connected to both outer sides of the two side plates through screws. There are four support plates, and the lower surface of the support plate is fixedly connected to the upper surface of the bottom frame. A dispersing mechanism is installed in the feeding frame. The lower surface of the side plate is in contact with the upper surface of the receiving frame, and the side surface of the receiving frame is fixedly connected to the support plate through screws.

[0004] When the above device is in use, the fertilizer is screened on the sieve plate. During the screening process, larger particle fertilizers are likely to block the sieve holes and are difficult to clean. Summary of the Utility Model

[0007] (2) Technical Solutions

[0008] In order to achieve the above purpose, the main technical solutions adopted by the utility model include:

[0009] A fertilizer screening machine includes a housing and support legs at the bottom of the housing. An elastic screen is arranged inside the housing cavity. The elastic screen is of an arc structure, and the middle part of the elastic screen bulges upward. A chute is formed at the inner wall position of the housing, and a slider adapted to the chute is arranged at the side wall position of the elastic screen. A hydraulic rod is fixedly installed at the bottom position of the elastic screen. First discharge ports are formed on the left and right sides of the housing, and a second discharge port is arranged at the bottom position of the housing. It is convenient to clean the sieve holes and ensure the screening efficiency.

[0010] Preferably, a blanking chute is installed at the first discharge port.

[0011] Preferably, a stirring and blanking mechanism is arranged above the housing.

[0012] Preferably, a vibration motor is fixedly installed at the bottom position of the elastic screen.

[0013] (III) Beneficial effects

[0014] The utility model provides a fertilizer screening machine, which has the following beneficial effects:

[0015] (1) During long-term use, the mesh holes on the elastic screen are easily blocked by large granular fertilizer particles. When the sieve holes need to be cleaned, the hydraulic rod contracts and extends, and the hydraulic rod drives the elastic screen to change its shape. The particles above the inner part of the sieve holes are pushed up and lifted, and the particles below the inner part of the sieve holes are extruded downward, so as to realize the cleaning of the elastic screen.

[0020] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0021] As Figures 1-3 shown, the fertilizer screening machine of this embodiment includes a housing 1 and support legs 2 at the bottom of the housing 1. An elastic screen 3 is arranged in the inner cavity of the housing 1. The elastic screen 3 is of an arc structure, and the middle of the elastic screen 3 bulges upward. A chute 4 is opened at the inner wall position of the housing 1, and a slider 5 adapted to the chute 4 is arranged at the side wall position of the elastic screen 3. A hydraulic rod 6 is fixedly installed at the bottom position of the elastic screen 3. The hydraulic rod 6 drives the elastic screen 3 to deform, and then extrudes the particles in the screen holes of the elastic screen 3. First discharge ports 7 are opened on the left and right sides of the housing 1. The first discharge ports 7 are used for discharging large-particle fertilizers. A second discharge port 8 is arranged at the bottom position of the housing 1. The second discharge port 8 is used for discharging small-particle fertilizers.

[0022] Furthermore, a discharge chute 9 is installed at the first discharge port 7.

[0023] Furthermore, a stirring and discharging mechanism is arranged above the housing 1. The equipment can be used in combination with a hoist or a stirring and discharging mechanism, eliminating the need for manual handling and feeding, and reducing labor intensity.

[0024] Furthermore, a vibration motor is fixedly installed at the bottom position of the elastic screen 3. The vibration motor causes the surface of the elastic screen 3 to vibrate, improving the screening speed.

[0025] Working principle: The elastic screen 3 can be a wire screen. During use, the equipment is used in combination with a hoist or a stirring and discharging mechanism. The fertilizer to be screened is lifted by the hoist and then falls onto the elastic screen 3, or the fertilizer to be screened is poured into the stirring and discharging mechanism and evenly fed onto the elastic screen 3. Since the elastic screen 3 is an arc-shaped mechanism with the middle bulging upward, the large-particle fertilizer particles roll along the screen of the elastic screen 3 to both sides and are discharged through the first discharge ports 7 and the discharge chute 9. The small-particle fertilizers pass through the mesh holes on the elastic screen 3 and are discharged through the second discharge port 8. After long-term use, the mesh holes of the elastic screen 3 are likely to be blocked. The hydraulic rod 6 contracts or extends, and the slider 5 on the elastic screen 3 slides in the chute 4. Driven by the hydraulic rod 6, the elastic screen 3 changes its shape, and the particles inside the screen holes are extruded, thereby realizing the cleaning of the elastic screen.
