Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer processing technology, specifically an organic fertilizer processing raw material screening machine. Background Technology

[0002] Organic fertilizer refers to carbon-containing organic materials that are mainly derived from plants and / or animals and have undergone fermentation and decomposition. Its functions are to improve soil fertility, provide plant nutrition, and improve crop quality. In the organic fertilizer processing flow, the raw material screening machine is the core equipment for realizing raw material pretreatment (removing impurities and grading screening).

[0003] Conventional raw material screening machines often use a vibrating motor to drive the entire screening machine to vibrate. The vibration source is then transmitted to the screening plate, and the raw materials are screened by the vibrating screening plate. At this time, the energy transmission conversion rate of the vibrating motor is low, and the noise is also high. It may also cause the screening plate to become clogged, affecting the screening effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the low energy transmission conversion rate of vibratory motors, high noise levels, and potential clogging of the screening plate that affects screening efficiency, this invention proposes a screening machine for organic fertilizer processing raw materials.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an organic fertilizer processing raw material screening machine, including a screening box, a large sieve plate and a small sieve plate are slidably connected on the inner wall of the screening box, and a vibration mechanism is provided on the screening box;

[0006] The vibration mechanism includes a first motor, which is fixedly connected to the side wall of the screening box via a mounting plate. The output end of the first motor is rotatably connected inside the screening box. A cross rod is fixedly connected to the output end of the first motor. The cross rod abuts against a large sieve plate and a small sieve plate. A slider is fixedly connected to the side of the small sieve plate. A guide rod is fixedly connected to the inner wall of the screening box. A spring is sleeved on the outer side of the guide rod. An mounting block is fixedly connected to the side of the large sieve plate. A hemispherical block is fixedly connected to the side of the mounting block.

[0007] Preferably, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the inner wall of the screening box.

[0008] Preferably, the slider is slidably connected to the inner wall of the screening box, the slider is slidably connected to the outer side of the guide rod, and a hemispherical block is slidably connected to the inner wall of the screening box.

[0009] Preferably, the upper end of the screening box is provided with a box cover, the upper end of the box cover is fixedly sleeved with a feed pipe, and a pretreatment mechanism is provided on the box cover.

[0010] Preferably, the pretreatment mechanism includes a second motor, which is fixedly installed on the upper end of the box cover. The output end of the second motor is rotatably connected to the feed pipe. A first bevel gear is fixedly connected to the output end of the second motor. A second bevel gear meshes with the first bevel gear. A connecting shaft is fixedly connected to the second bevel gear. A bracket is fixedly connected to the inner wall of the feed pipe. The bracket and the connecting shaft are installed through bearings. A crushing blade is fixedly connected to the outer side of the connecting shaft.

[0011] Preferably, the lower end of the screening box is fixedly connected to a discharge pipe, the front of the screening box is provided with a door, and the lower end of the screening box is fixedly connected to a support leg.

[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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a raw material screening machine for organic fertilizer processing. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An organic fertilizer processing raw material screening machine includes a screening box 1, a large sieve plate 2 and a small sieve plate 3 that are slidably connected to the inner wall of the screening box 1, and a vibration mechanism 4 is provided on the screening box 1.

[0026] The vibration mechanism 4 includes a first motor 41, which is fixedly connected to the side wall of the screening box 1 via a mounting plate. The output end of the first motor 41 is rotatably connected inside the screening box 1. A cross rod 42 is fixedly connected to the output end of the first motor 41, and the cross rod 42 abuts against the large screen plate 2 and the small screen plate 3. A slider 43 is fixedly connected to the side of the small screen plate 3. A guide rod 44 is fixedly connected to the inner wall of the screening box 1, and a spring 45 is sleeved on the outer side of the guide rod 44. A mounting block 46 is fixedly connected to the side of the large screen plate 2, and a hemispherical block 47 is fixedly connected to the side of the mounting block 46. One end of the spring 45 is fixedly connected to the slider 43, and the other end of the spring 45 is fixedly connected to the inner wall of the screening box 1. The slider 43 is slidably connected to the inner wall of the screening box 1 and slidably connected to the outer side of the guide rod 44. The hemispherical block 47 is slidably connected to the inner wall of the screening box 1. The screen is divided into vertical and horizontal bars. The vertical bar of the cross bar 42 is longer than the horizontal bar. The cross bar 42 can be driven to rotate by starting the first motor 41. Since the vertical bar of the cross bar 42 is longer than the horizontal bar, the large screen plate 2 and the small screen plate 3 can be moved under the action of the cross bar 42. The side of the large screen plate 2 is fixed with a mounting block 46. The side of the mounting block 46 is fixed with a hemispherical block 47. The hemispherical block 47 abuts against the groove opened in the inner wall of the screening box 1. The hemispherical block 47 is spherical, which can reduce the contact area and thus reduce the friction. This allows the large screen plate 2 to bounce up and down under the cross bar 42 and its own weight, thus performing primary screening. The side of the small screen plate 3 is fixed with a slider 43. The small screen plate 3 can bounce up and down by the tension generated by the spring 45 and the action of the cross bar 42. The aperture of the small screen plate 3 is smaller than that of the large screen plate 2, which can perform secondary screening. Both the large screen plate 2 and the small screen plate 3 have a certain degree of elasticity, which facilitates movement.

[0027] Reference Figure 2 and Figure 6 The upper end of the screening box 1 is provided with a box cover 5, and a feed pipe 6 is fixedly sleeved on the upper end of the box cover 5. A pretreatment mechanism 7 is provided on the box cover 5. The pretreatment mechanism 7 includes a second motor 71, which is fixedly installed on the upper end of the box cover 5. The output end of the second motor 71 is rotatably connected to the feed pipe 6. A first bevel gear 72 is fixedly connected to the output end of the second motor 71. A second bevel gear 73 meshes with the first bevel gear 72. A connecting shaft 74 is fixedly connected to the second bevel gear 73. A bracket 75 is fixedly connected to the inner wall of the feed pipe 6. The bracket 75 is connected to the connecting shaft 74. The connecting shaft 74 is mounted via bearings, and a crushing blade 76 is fixedly connected to the outside of the connecting shaft 74. The raw materials to be screened can be fed through the feed pipe 6. At the same time, the second motor 71 is started, which drives the first bevel gear 72 to rotate. Through the cooperation of the first bevel gear 72 and the second bevel gear 73, the connecting shaft 74 fixed on the second bevel gear 73 can rotate. The rotation of the connecting shaft 74 can cause the crushing blade 76 to rotate. The crushing blade 76 can crush and stir the raw materials, avoid material blockage, and facilitate the breaking up of clumps of raw materials for easy screening.

[0028] Reference Figure 1 and Figure 4 The lower end of the screening box 1 is fixedly connected to the discharge pipe 8, the front of the screening box 1 is provided with a door 9, and the lower end of the screening box 1 is fixedly connected to the support leg 10. The raw material that has passed the secondary screening can be discharged through the discharge pipe 8. The door 9 can be opened to collect the raw material that remains on the large screen plate 2 and the small screen plate 3. The support leg 10 facilitates the placement of the device.

[0029] Working principle: Raw materials to be screened can be fed through the feed pipe 6. Simultaneously, the second motor 71 is started, driving the first bevel gear 72 to rotate. The engagement of the first bevel gear 72 and the second bevel gear 73 causes the connecting shaft 74 fixed on the second bevel gear 73 to rotate. The rotation of the connecting shaft 74 causes the crushing blade 76 to rotate, thus crushing and mixing the raw materials, preventing clogging and facilitating the breaking up of clumps for easier screening. Starting the first motor 41 drives the crossbar 42 to rotate. Since the vertical length of the crossbar 42 is greater than the horizontal length, the crossbar 42 causes the large screen plate 2 and the small screen plate 3 to move. A mounting block 46 is fixed to the side of the sieve plate 2. A hemispherical block 47 is fixed to the side of the mounting block 46. The hemispherical block 47 abuts against the groove opened in the inner wall of the screening box 1. The hemispherical block 47 is spherical, which can reduce the contact area and thus reduce the friction. This allows the large sieve plate 2 to bounce up and down under the cross rod 42 and its own weight, thus performing primary screening. A slider 43 is fixed to the side of the small sieve plate 3. The small sieve plate 3 can bounce up and down by the tension generated by the spring 45 and the action of the cross rod 42. The aperture of the small sieve plate 3 is smaller than that of the large sieve plate 2, which can perform secondary screening. The discharge pipe 8 can discharge the raw material that has passed through the secondary screening. The box door 9 can be opened to collect the raw material remaining on the large sieve plate 2 and the small sieve plate 3.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
