[0001] This utility model relates to the field of compound fertilizer preparation technology, and in particular to a material dispensing mechanism for compound fertilizer preparation. Background Technology
[0002] In the preparation of compound fertilizers, the screening of raw materials is a crucial step. Screening can control the particle size of fertilizers, making the fertilizer particles more uniform. Uniform particle size distribution is conducive to crop absorption and utilization, which can improve the application effect of fertilizers. At the same time, uniform particle size can also prevent dust from scattering during fertilization, improve fertilizer performance, and prolong fertilizer effect.
[0003] Existing material distribution mechanisms in compound fertilizer preparation achieve the purpose of screening raw materials by vibrating the screening screen. When faced with a large amount of raw materials, the raw materials accumulate on the surface of the screening screen, causing blockage and reducing screening efficiency. Therefore, a material distribution mechanism for compound fertilizer preparation is proposed to solve the above problems. Utility Model Content

[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the initial screening of raw materials is achieved by setting up the material distribution component. After the raw materials are put in, the auger inside the feeding barrel pushes the raw materials upward and discharges them through the top of the feeding barrel, thereby turning the raw materials over. The turning process effectively avoids the blockage of the conical screening plate, and also ensures the uniformity and efficiency of the raw material screening.
[0015] 2. In this utility model, the setting of the picking component makes the picking and replacement of the conical screening plate extremely convenient. By lifting the handle upward, the connecting rod drives the conical screening plate to rise as a whole. At the same time, the baffle automatically descends under the action of gravity and closes the feeding channel between the two baffles, thereby ensuring that the screening plate will not cause leakage or scattering of raw materials during the removal process. This simplifies the replacement process of the screening plate and improves the safety and convenience of operation. Attached Figure Description

[0021] 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.
[0022] Reference Figure 1 - Figure 3This utility model provides an embodiment of a material dispensing mechanism for compound fertilizer preparation, comprising support legs 1, with a dispensing bucket 2 fixedly connected to the top of four support legs 1, a discharge pipe 5 fixedly connected to the bottom surface of the dispensing bucket 2, and a dispensing assembly 4 disposed inside the dispensing bucket 2. The dispensing assembly 4 includes a spacer ring 41 fixedly connected to the inner wall surface of the middle part of the dispensing bucket 2, a guide plate 42 uniformly fixedly connected to the top surface of the spacer ring 41, and a conical sieve plate 43 placed on the top surface of the spacer ring 41. The edge sidewall surface of the conical sieve plate 43... The material distribution bin 2 has uniformly spaced guide grooves 44. A feeding bin 45 is fixedly connected to the inner surface of the center of the material distribution bin 2. An auger 46 is rotatably connected to the inner surface of the bottom of the feeding bin 45. A drive motor 47 is fixedly connected to the bottom surface of the material distribution bin 2. Feed inlets 48 are uniformly spaced on the lower surface of the feeding bin 45. Raw materials are fed into the top opening of the material distribution bin 2 and fall onto the conical screening plate 43. The raw materials will be initially screened according to particle size. Larger particles will slide down the inclined surface of the conical screening plate 43, while smaller particles will pass through the conical screening plate 43. The particles fall through the sieve holes into the lower distribution bin 2. The auger 46 inside the feeding bin 45 is driven to rotate by the drive motor 47. Larger particles slide down the inclined surface of the conical screening plate 43 and enter the feeding bin 45 through the feed channel and feed inlet 48. The rotation of the auger 46 pushes the large particles inside the feeding bin 45 upwards until they are discharged through the top of the feeding bin 45. This achieves the agitation of the screened material, preventing blockage of the conical screening plate 43 and ensuring more uniform screening. After screening is complete, the larger particles will stop... Smaller particles remain on the surface of the conical screening plate 43, while smaller particles fall through the screen holes of the conical screening plate 43 into the distribution bin 2 below. The surface of the conical screening plate 43 is provided with a picking component 3. The top of the distribution bin 2 is open, and the center of the conical screening plate 43 is a circular opening. The guide plates 42 are all slidably connected to the guide grooves 44. The conical screening plate 43 is slidably connected to the outer wall of the feeding bin 45 through its central opening. The output shaft of the drive motor 47 passes through the bottom of the distribution bin 2 and is fixedly connected to the bottom of the auger 46. The top of the feeding bin 45 is open.
[0023] Reference Figure 1 - Figure 3The picking component 3 includes a stop bar 31 uniformly fixedly connected to the surface of the feeding hopper 45; a clamping plate 32 uniformly fixedly connected to the surface of the conical screening plate 43; limit grooves 33 on both sides of the clamping plate 32; a baffle 34 slidably connected between two clamping plates 32; limit plates 35 fixedly connected to both sides of the baffle 34; a trigger plate 36 fixedly connected to the top surface of the baffle 34; a connecting rod 37 uniformly fixedly connected to the surface of the conical screening plate 43; and a handle 38 fixedly connected to the top surface of the connecting rod 37. Lifting the handle 38 upwards causes the conical screening plate 43 to move as a whole via the connecting rod 37. As the conical screening plate 43 rises, the baffle 34 disengages from the baffle rod 31 and automatically descends due to gravity. The limiting plate 35 slides within the limiting groove 33 until the baffle 34 closes the feeding channel formed between the two clamping plates 32. At this point, the conical screening plate 43, along with the larger particles screened on its surface, can be smoothly removed. The top surface of the baffle rod 31 abuts against the bottom surface of the baffle 34. The feeding channel is formed between the two clamping plates 32. The limiting plates 35 are slidably connected inside the limiting groove 33. The connecting rod 37 is set to at least four rods, and the handle 38 is located directly above the feeding bucket 45.
[0024] Working Principle: During use, raw materials are fed into the top opening of the distribution hopper 2. The raw materials fall onto the conical screening plate 43, where they undergo preliminary screening based on particle size. Larger particles slide down the inclined surface of the conical screening plate 43, while smaller particles fall through the screen holes into the distribution hopper 2 below. The auger 46 inside the feeding hopper 45 is driven by the drive motor 47 to rotate. Larger particles slide down the inclined surface of the conical screening plate 43 and enter the feeding hopper 45 through the feeding channel and inlet 48. The rotation of the auger 46 pushes the large particles upwards until they are discharged through the top of the feeding hopper 45, thus achieving the agitation of the screened raw materials, preventing clogging of the conical screening plate 43, and ensuring... To ensure more uniform screening of raw materials, after screening, larger particles will remain on the surface of the conical screening plate 43, while smaller particles will fall into the distribution bucket 2 below through the screen holes of the conical screening plate 43. At this time, lift the handle 38 upwards. The handle 38 drives the conical screening plate 43 to rise as a whole through the connecting rod 37. During the rising process of the conical screening plate 43, the baffle 34 disengages from the abutment of the baffle rod 31 and automatically descends due to gravity. The limiting plate 35 slides in the limiting groove 33 until the baffle 34 closes the feeding channel formed between the two clamping plates 32. At this time, the conical screening plate 43 along with the larger particles screened on its surface can be easily removed, while the smaller particles will be discharged through the discharge pipe 5. Thus, the entire screening process is completed.
