Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to a raw material mixer for nitrogen-potassium fertilizer production. Background Technique

[0002] Nitrogen-potassium fertilizer is a common fertilizer in agriculture and is widely used in the field of agricultural planting technology. When producing nitrogen-potassium fertilizer, there are various types of raw materials, and multiple raw materials need to be mixed and processed to produce nitrogen-potassium fertilizer. Therefore, the raw material mixer is an essential processing equipment in the technical field of nitrogen-potassium fertilizer production and processing.

[0003] In the prior art, there are various types of mixers. The Chinese utility model patent CN221310219U discloses a horizontal single-shaft mixer for molecular sieve preparation. The mixer includes a mixing cylinder arranged on a machine tool. A mixing roller is rotatably connected inside the mixing cylinder, and a plurality of flying knife mixers are arranged around the outside of the mixing roller. The mixer further includes a scraping mechanism and a moving mechanism. The scraping mechanism includes a first scraping plate and a second scraping plate. The second scraping plate abuts against the inner wall of the mixing cylinder. During use, the mixing roller rotates to stir the materials in the mixing cylinder, and the first scraping plate and the second scraping plate are driven to rotate during the rotation of the mixing roller. The first scraping plate and the second scraping plate scrape off the materials adhering to the inner wall of the mixing cylinder, avoiding waste of materials.

[0004] Although the above mixer can effectively improve the utilization efficiency of materials, the above mixer still has the following defects during use: Since the mixing cylinder is installed on the machine tool and the mixing cylinder is loaded with materials during use, the mixing cylinder bears a heavy load. After long-term use, the mixing cylinder and the machine tool are prone to looseness, resulting in poor stability of the mixing cylinder and causing certain inconvenience in use. For this reason, we propose a raw material mixer for nitrogen-potassium fertilizer production. Content of the Utility Model

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0033] As Figure 1 and Figure 2 shown, it is a schematic structural diagram of the raw material mixer in this embodiment. The raw material mixer in this embodiment is used to stir and mix the raw materials for producing nitrogen potassium fertilizer to facilitate the processing and production of nitrogen potassium fertilizer. In this embodiment, the mixer includes a machine tool 100 and a mixing unit 200 arranged on the machine tool 100. The mixing unit 200 includes a mixing drum 201. Side plates 101 are fixedly installed on both sides of the machine tool 100. A mixing drum 201 is arranged between the side plates 101. The top of the mixing drum 201 is provided with a feeding port, and the bottom is provided with a discharging port. The raw materials for producing nitrogen potassium fertilizer enter the mixing drum 201 through the feeding port at the top of the mixing drum 201, and are effectively stirred and mixed evenly in the mixing drum 201 and then discharged from the discharging port. In addition, in this embodiment, a driving mechanism is also assembled on one side of the side plate 101, and a mixing assembly 300 is also arranged in the mixing drum 201. The driving mechanism is used to drive the mixing assembly 300 to rotate to stir the raw materials in the mixing drum 201.

[0034] Since the raw materials are located inside the mixing drum 201, the mixing drum 201 is heavily loaded. The two ends of the mixing drum 201 are assembled between the side plates 101 of the machine tool 100. Due to the heavy load of the mixing drum 201, looseness is likely to occur between the two ends of the mixing drum 201 and the side plates 101 after long-term use. To solve this problem, in this embodiment, the two ends of the mixing drum 201 are fixedly installed on the side plates 101 through a plurality of bolts, thereby realizing the relative fixation between the mixing drum 201 and the side plates 101. To further ensure the fixation effect between the mixing drum 201 and the side plates 101, in this embodiment, a stabilizing component 102 is also assembled between the side plates 101. The stabilizing component 102 is assembled between the side plates 101 to support the side plates 101, thereby enhancing the stability between the side plates 101 and the mixing drum 201 and ensuring the stable effect of the mixing drum 201.

[0035] As Figure 7 and Figure 8 shown, in this embodiment, the stabilizing component 102 includes a fixed cylinder 102a. The fixed cylinder 102a is fixedly installed on one of the side plates 101, and the inside of the fixed cylinder 102a is hollow with one end open. A sliding rod 102b is slidably installed inside the fixed cylinder 102a. One end of the sliding rod 102b is slidably installed in the fixed cylinder 102a, and the other end extends to the outside of the fixed cylinder 102a and abuts against the other side plate 101. An expansion spring 102d is also assembled inside the fixed cylinder 102a. One end of the expansion spring 102d is connected to the inner wall of the fixed cylinder 102a, and the other end is connected to the sliding rod 102b. And the expansion spring 102d is in a compressed state. Therefore, due to the elastic force, the compression spring 102d drives the end of the sliding rod 102b to press against the side plate 101, so that the stabilizing component 102 supports the two side plates 101. Since the side plates 101 and the ends of the mixing drum 201 are locked with bolts, when the stabilizing component 102 supports the side plates 101, the stability between the side plates 101 and the mixing drum 201 is improved, thereby improving the stable effect of the mixing drum 201.

[0036] As Figure 8 shown, in this embodiment, to ensure that the sliding rod 102b can only slide along the length direction of the fixed cylinder 102a, a sliding groove is opened on the fixed cylinder 102a, and a spline 102c is fixedly installed on the surface of the sliding rod 102b. After the sliding rod 102b is slidably installed inside the fixed cylinder 102a, the spline 102c is slidably assembled in the sliding groove. When the sliding rod 102b slides relative to the fixed cylinder 102a, the spline 102c slides in the sliding groove. In this embodiment, the sliding rod 102b is driven to slide by the working of the expansion spring 102d, and the spline 102c slides in the sliding groove, so that the sliding rod 102b presses against the surface of the side plate 101, thereby realizing the improvement of the stable effect between the mixing drum 201 and the side plates 101.

[0037] In addition, as Figure 3 and Figure 6 shown, in this embodiment, a stirring assembly 300 is disposed inside the stirring cylinder 201, and a driving mechanism is disposed on one side of the machine tool 100. The driving mechanism is connected to the stirring assembly 300, and the stirring assembly 300 can be driven to rotate by the driving mechanism to stir the raw materials in the stirring cylinder 201. In this embodiment, the stirring assembly 300 includes a rotating rod 301. The rotating rod 301 is connected to the driving mechanism, and the driving mechanism operates to drive the rotating rod 301 to rotate. In this embodiment, the rotating rod 301 has a square structure, and a mounting member 302 is detachably mounted on the rotating rod 301. A stirring member 303 is connected to the mounting member 302. When the rotating rod 301 rotates, the mounting member 302 and the stirring member 303 can be driven to rotate, so as to stir the raw materials in the stirring cylinder 201 through the stirring member 303. After being stirred evenly, the materials are discharged through the discharge port of the stirring cylinder 201.

[0038] In this embodiment, the raw materials for producing nitrogen-potassium fertilizer enter the stirring cylinder 201 through the feed port of the stirring cylinder 201. The driving mechanism operates to drive the stirring assembly 300 to rotate, and the stirring member 303 in the stirring assembly 300 rotates to stir the raw materials in the stirring cylinder 201. After being stirred evenly, the materials are discharged through the discharge port of the stirring cylinder 201. In addition, since the stirring cylinder 201 has a heavy load and is prone to looseness with the machine tool 100 after long-term use, in this embodiment, side plates 101 are installed on both sides of the machine tool 100, and the side plates 101 are supported by a stabilizing assembly 102, so that the stability between the stirring cylinder 201 and the side plates 101 is relatively strong. Embodiment 2

[0039] As Figure 3 and Figure 4 shown, it is a schematic structural diagram of the stirring cylinder 201 in this embodiment. The difference between the stirring cylinder 201 in this embodiment and that in Embodiment 1 is that the stirring cylinder 201 is provided with an opening, and a rotating door 201a is provided at the opening. The rotating door 201a can rotate relative to the stirring cylinder 201 to open and close the opening for easy maintenance of the inside of the stirring cylinder 201. As Figure 3 and Figure 4 shown, in this embodiment, the rotating door 201a has an arc-shaped structure that matches the side wall of the stirring cylinder 201. In this embodiment, a driver 201b is hinged to the side wall of the stirring cylinder 201, and the other end of the driver 201b is hinged to the rotating door 201a. In this embodiment, the driver 201b operates to expand and contract, so as to drive the rotating door 201a to rotate relative to the stirring cylinder 201 to open and close the opening, so as to facilitate the maintenance of the stirring cylinder 201 by operators.

[0040] In this embodiment, when the mixing drum 201 needs to be overhauled, the driver 201b works to contract, causing the rotating door 201a to rotate relative to the side wall of the mixing drum 201, exposing the opening for the operators to overhaul the mixing drum 201. Additionally, when the opening needs to be sealed, the driver 201b works to extend, driving the rotating door 201a to rotate to close the opening.

[0041] In this embodiment, to ensure the stable effect after the rotating door 201a closes the opening, a locking structure 202 is further provided between the mixing drum 201 and the rotating door 201a. The locking structure 202 is used to relatively fix the rotating door 201a and the mixing drum 201.

[0042] As Figure 5 shown, in this embodiment, a rotating member 202a is installed on the side wall of the mixing drum 201. A hanging rod 202b is connected to the rotating member 202a, and a blocking member 202c is further provided on the rotating door 201a. In this embodiment, after the hanging rod 202b is hung on the blocking member 202c, the rotation of the rotating member 202a realizes the locking between the rotating door 201a and the mixing drum 201, thereby improving the relative fixation between the rotating door 201a and the mixing drum 201.

[0043] The working principle of the present utility model is as follows: The raw materials for producing nitrogen-potassium fertilizers enter the mixing drum 201 through the feed port of the mixing drum 201. The driving mechanism works to drive the mixing assembly 300 to rotate. The rotating rod 301 in the mixing assembly 300 drives the mixing member 303 to rotate through the mounting member 302 to mix the raw materials in the mixing drum 201. After being evenly stirred and mixed, they are discharged through the discharge port at the bottom of the mixing drum 201. Additionally, the mixing drum 201 is installed between the side plates 101 at the top of the machine tool 100. A stabilizing assembly 102 is further provided between the side plates 101 to improve the stable effect between the mixing drum 201 and the side plates 101. The sliding rod 102b of the stabilizing assembly 102 can slide relative to the fixed cylinder 102a, and the action of the telescopic spring 102d improves the stable effect between the mixing drum 201 and the side plates 101. Additionally, for the convenience of overhauling the mixing drum 201, in this embodiment, an opening is provided on the side wall of the mixing drum 201, and the opening is opened and closed by the rotating door 201a. The rotating door 201a is rotated by the driver 201b to facilitate the operators to overhaul the mixing drum 201. Additionally, in this embodiment, after the rotating door 201a closes the opening, it is locked by the locking structure 202, realizing the relative fixation between the rotating door 201a and the side wall of the mixing drum 201.

[0044] The control method of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common general knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices. Therefore, the control method and circuit connection of the present utility model will not be explained in detail herein.
