Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to a fertilizer mixing and stirring machine frame. Background Technology

[0002] Fertilizers are typically composed of various raw materials (such as nitrogen, phosphorus, potassium, and trace elements). During the fertilizer production process, the fertilizer needs to be thoroughly mixed and stirred. Uneven mixing can lead to localized excessive or insufficient nutrients, affecting crop growth. A double auger mixer is a device that achieves efficient fertilizer mixing by rotating two parallel spiral shafts simultaneously. Typically, the two spiral shafts drive the fertilizer to convect, shear, and diffuse within the mixing tank. Under the propulsion of the spiral blades, the fertilizer undergoes both axial and radial motion, thereby quickly achieving uniform mixing.

[0003] In the operation of existing twin auger mixers, raw materials are usually poured directly into the hopper at the top of the mixer by a loader. Due to the impact and fluidity, the material will quickly accumulate and overflow to the other side, resulting in material waste. In addition, the overflowing powdery material is easy to generate dust, pollute the workshop environment, and requires manual cleaning, which increases labor intensity. Utility Model Content

[0004] The purpose of this utility model is to provide a fertilizer mixing and stirring frame to solve the problem mentioned in the background art. In the process of using the existing double screw mixer, the raw materials are usually poured directly into the hopper at the top of the double screw mixer by a loader. Due to the impact force and fluidity, the material will quickly accumulate and overflow to the other side, resulting in raw material waste. In addition, the overflowing powdery material is easy to generate dust, pollute the workshop environment, and requires manual cleaning, which increases labor intensity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fertilizer mixing and stirring machine frame, comprising a support frame and a material blocking part:

[0006] The support frame has a mixing chamber at the top, with two rotating spiral shafts inside for stirring and mixing. A hopper is located at the top of the mixing chamber, and a discharge port is located at the bottom. A baffle is located at the top of the mixing chamber and has a receiving shell at the top. A lifting plate is vertically slidably mounted inside the receiving shell, and a transmission rod is rotatably mounted at the bottom of the lifting plate. An adjusting block is horizontally slidably mounted inside the receiving shell, with its top rotatably connected to the end of the transmission rod away from the lifting plate. The horizontal sliding of the adjusting block drives the transmission rod to rotate, pushing the lifting plate to move vertically.

[0007] By adopting the above technical solution, fertilizer can be efficiently mixed through the bidirectional rotation of the screw shaft. At the same time, by adjusting the movement of the adjustment block to control the raising and lowering of the lifting plate, the lifting plate on one side of the loader can be lowered to facilitate feeding, while the lifting plate on the side away from the loader can be raised to prevent material from accumulating in the mixing chamber and overflowing from the other side.

[0008] Preferably, there are two storage shells, which are arranged symmetrically on both sides of the mixing chamber.

[0009] By adopting the above technical solution, the lifting plate on either side can be raised or lowered.

[0010] Preferably, the baffle part also has a storage cavity inside the storage shell, and the storage cavity has grooves on both sides. The lifting plate has sliders on both sides, which are embedded in the grooves and vertically slidably connected to the storage shell.

[0011] By adopting the above technical solution, the movement trajectory of the lifting plate can be limited by the cooperation of the slider and the slide groove, preventing it from shifting or getting stuck in the storage cavity.

[0012] Preferably, the baffle part also has a bidirectional lead screw that is laterally rotatably disposed inside the housing. One end of the bidirectional lead screw extends to the outside of the housing and is provided with a handle. The adjusting block has a threaded groove inside. The bidirectional lead screw passes laterally through the threaded groove and is nested and threadedly connected to the adjusting block.

[0013] By adopting the above technical solution, the bidirectional lead screw can be driven to rotate by rotating the handle, and the two adjusting blocks can be moved in opposite directions by the meshing of the threaded groove, so as to realize the smooth lifting of the lifting plate.

[0014] Preferably, there are two adjusting blocks, which are arranged in a mirror-symmetrical manner along the center of the lifting plate, and both adjusting blocks are connected to the same bidirectional lead screw with a nested thread.

[0015] By adopting the above technical solution, the displacement of the two adjusting blocks can be synchronously controlled by a two-way lead screw, ensuring that the force exerted by the transmission rod on the lifting plate is symmetrically distributed, and avoiding deformation of the mechanism caused by unilateral force.

[0016] Preferably, the baffle also has a rotating groove a at the bottom of the lifting plate, one end of the transmission rod is embedded in the rotating groove a and rotatably connected to the lifting plate, and the top of the adjusting block is provided with a rotating groove b, the other end of the transmission rod is embedded in the rotating groove b and rotatably connected to the adjusting block.

[0017] By adopting the above technical solution, the hinged design of rotating groove a and rotating groove b allows the transmission rod to rotate freely when the adjusting block moves laterally, thus converting the horizontal motion into the vertical motion of the lifting plate.

[0018] Preferably, the baffle section also has a baffle plate disposed on the top of the mixing chamber, the two ends of which abut against the lifting plate.

[0019] By adopting the above technical solution, a closed fence structure can be formed with the raised lifting plate to prevent fertilizer from spilling out.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by setting up a material blocking part, the fertilizer can be efficiently mixed through the bidirectional rotation of the screw shaft. At the same time, by adjusting the movement of the adjusting block to control the raising and lowering of the lifting plate, the lifting plate on one side of the loader can be lowered to facilitate material loading, while the lifting plate on the side away from the loader can be raised, reducing the occurrence of material accumulation in the mixing chamber overflowing from the other side and improving the loading efficiency of the loader.

[0028] 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.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a fertilizer mixing and stirring machine frame, including a support frame 1 and a material blocking part 2.

[0031] The top of the support frame 1 is provided with a mixing chamber 101. Inside the mixing chamber 101, there are two rotating spiral shafts 102 for stirring and mixing. The spiral shafts 102 are equipped with a power component. The top of the mixing chamber 101 is provided with a hopper 104, and the bottom of the mixing chamber 101 is provided with a discharge port 103. The fertilizer can be efficiently mixed by the bidirectional rotation of the spiral shafts 102.

[0032] The baffle 2 is located on the top of the mixing chamber 101. The baffle 2 has a receiving shell 201 located on the top of the mixing chamber 101. A lifting plate 206 is vertically slidably arranged inside the receiving shell 201. A transmission rod 209 is rotatably arranged at the bottom of the lifting plate 206. An adjusting block 210 is horizontally slidably arranged inside the receiving shell 201. The top of the adjusting block 210 is rotatably connected to the end of the transmission rod 209 away from the lifting plate 206. The horizontal sliding of the adjusting block 210 drives the transmission rod 209 to rotate and push the lifting plate 206 to move vertically. The lifting plate 206 can be raised and lowered by the movement of the adjusting block 210. When feeding materials, the lifting plate 206 on the side of the loader can be lowered to facilitate feeding, and the lifting plate 206 on the side away from the loader can be raised to prevent the material in the mixing chamber 101 from accumulating and overflowing from the other side.

[0033] Example 2

[0034] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a fertilizer mixing and stirring machine frame, including a material baffle 2.

[0035] There are two storage shells 201, which are mirror-symmetrically arranged on both sides of the mixing chamber 101, allowing the lifting plate 206 on either side to rise or fall.

[0036] The baffle part 2 also has a storage cavity 202 inside the storage shell 201. The storage cavity 202 has grooves 203 on both sides. The lifting plate 206 has sliders 207 on both sides. The sliders 207 are embedded in the grooves 203 and are vertically slidably connected to the storage shell 201. The movement trajectory of the lifting plate 206 can be restricted by the cooperation between the sliders 207 and the grooves 203, so as to prevent it from shifting or getting stuck in the storage cavity 202.

[0037] A bidirectional lead screw 204 is horizontally rotatably installed inside the storage shell 201. One end of the bidirectional lead screw 204 extends to the outside of the storage shell 201 and is provided with a handle 205. The adjusting block 210 has a threaded groove 211 inside. The bidirectional lead screw 204 passes horizontally through the threaded groove 211 and is nested and threadedly connected to the adjusting block 210. The bidirectional lead screw 204 can be driven to rotate by rotating the handle 205. The engagement of the threaded groove 211 drives the two adjusting blocks 210 to move in opposite directions, so as to realize the smooth lifting and lowering of the lifting plate 206.

[0038] There are two adjusting blocks 210. The two adjusting blocks 210 are arranged in a mirror symmetrical manner along the center of the lifting plate 206. Both adjusting blocks 210 are nested and threadedly connected to the same bidirectional lead screw 204. The displacement of the two adjusting blocks 210 can be controlled synchronously by the bidirectional lead screw 204 to ensure that the force of the transmission rod 209 on the lifting plate 206 is symmetrically distributed, and to avoid deformation of the mechanism caused by unilateral force.

[0039] A rotating groove a208 is provided at the bottom of the lifting plate 206. One end of the transmission rod 209 is embedded in the rotating groove a208 and rotatably connected to the lifting plate 206. A rotating groove b212 is provided at the top of the adjusting block 210. The other end of the transmission rod 209 is embedded in the rotating groove b212 and rotatably connected to the adjusting block 210. Through the hinge design of the rotating groove a208 and the rotating groove b212, the transmission rod 209 can rotate freely when the adjusting block 210 moves laterally, thus converting the horizontal movement into the vertical movement of the lifting plate 206.

[0040] A baffle plate 213 is fixedly installed on the top of the mixing bin 101. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. The two ends of the baffle plate 213 abut against the lifting plate 206, which can form a closed fence structure with the lifting plate 206 after it rises to prevent fertilizer from overflowing.

[0041] Working principle: First, when the loader feeds material from the left side of the mixing bin 101, the rotating handle 205 causes the two adjusting blocks 210 on the left to move inward simultaneously, driving the left lifting plate 206 down to the low position of the hopper 104 opening, making it easier for the material to be poured into the bin. At the same time, the two adjusting blocks 210 on the right move outward simultaneously, driving the right lifting plate 206 up, forming a closed structure with the baffle plate 213 to prevent the material from overflowing from the right side. After the fertilizer enters the mixing bin 101 from the downward side of the hopper 104, the bidirectional rotating spiral shaft 102 efficiently stirs and mixes the material. After mixing is completed, the material is discharged from the discharge port 103.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
