Description

Technical Field

[0001] The utility model relates to the field of biological fertilizer disposal equipment, in particular to a biological fertilizer processing device. Background Art

[0002] In recent years, microbial fertilizer has been widely promoted in the agricultural field because it is suitable for use on various crops, which is in sharp contrast to the specificity and limitations of ordinary biofertilizers and overcomes the inherent weaknesses of ordinary biofertilizers. However, in the production process of microbial fertilizers, when the raw materials are processed into finished microbial fertilizers, the lumpy microbial fertilizers must first be processed and then the microbial fertilizer particles must be screened. Particles that are too large or too small are not conducive to the use effect of the microbial fertilizer and the growth of crops. At the same time, the microbial fertilizers are often relatively moist after preparation, so they need to be dried. Therefore, the processing device of microbial fertilizers is extremely important. The current screening device does not screen the microbial fertilizer particles sufficiently, resulting in a reduced utilization rate of the microbial fertilizer particles and low screening efficiency, which affects the production capacity of the microbial fertilizer particles. At the same time, after screening, a new device must be found for drying, which greatly reduces efficiency. Moreover, if the microbial fertilizers stored for a long time encounter lumps, they can be directly crushed and screened for re-collection. To this end, we provide a device that integrates microbial fertilizer screening and drying, a biofertilizer processing device. Utility Model Content

[0003] A biological fertilizer processing device comprises a first conveyor belt and a first-level screening device connected to the first conveyor belt, the first-level screening device is connected to the second-level screening device through a second conveyor belt, the second-level screening device comprises a second box body and a second feed port arranged on the top thereof, wherein the second conveyor belt is connected to the second feed port; wherein the interior of the second box body comprises, from top to bottom, a horizontally fixed second filter screen, a screening box, and a vibration device; the vibration device is located at the bottom of the screening box, and causes the screening box to vibrate up and down through vibration; a third discharge port is provided at the bottom of the screening box; and further comprises a stirring device, which is connected to the second box body through a channel, and a fifth discharge port is provided at the bottom of the stirring device.

[0004] The untreated block biological fertilizer enters the primary screening device through the first conveyor belt for preliminary screening. After screening, the fertilizer passes through the second conveyor belt and the second feed port into the second box of the secondary screening device. The fertilizer entering the second box falls onto the second filter net. The fertilizer filtered by the second filter net falls into the screening box. The vibration device vibrates up and down, causing the screening box to vibrate up and down to shake the fertilizer, which on the one hand breaks the block fertilizer and on the other hand accelerates the falling of the fertilizer. The fertilizer that has been screened and broken enters the stirring device through the third discharge port and the channel, and falls out through the fifth discharge port of the stirring device after stirring.

[0005] Preferably, it also includes two connecting rods hingedly arranged on the inner wall of the second box body, the two connecting rods are relatively arranged on both sides of the screening box and connected to the screening box, and a horizontally fixed third filter screen is also provided inside the screening box; it also includes a fourth discharge port, the fourth discharge port is located at the bottom of the second box body, and is arranged opposite to the third discharge port, and the second box body is connected to the stirring device through the fourth discharge port.

[0006] The screening box is suspended inside the second box body by connecting rods on both sides. When the vibration device vibrates the screening box, the screening box shakes up and down, vibrating and screening the bacterial fertilizer. The bacterial fertilizer passing through the screening box falls into the third discharge port. The third discharge port and the fourth discharge port are opposite to each other, and the bacterial fertilizer then falls into the stirring device through the fourth discharge port.

[0007] Preferably, there are two vibration devices, which are located on the corresponding two sides of the bottom of the screening box. The vibration device consists of two rotating disks arranged symmetrically on the left and right, a crankshaft connected between the two rotating disks, a push rod connected to the crankshaft, and a double-headed drive motor connected to the crankshaft. The push rod passes through the limiting hole arranged at the bottom of the second box body and rests on one side of the bottom of the screening box.

[0008] A vibration device is set at the symmetrical positions on both sides of the bottom of the screening box, so that the screening box is in a relatively balanced state when vibrating. The vibration device is composed of a crank mechanism. The motor drives the vibration device to make the push rod reciprocate up and down. A limiting hole is provided at the bottom of the second box body. The push rod passes through the limiting hole and rests on the bottom of the screening box. The limiting hole can ensure that the push rod reciprocates up and down. The left and right vibration devices work at the same time, and the push rod presses against the screening box up and down at the same time to make the screening box vibrate up and down.

[0009] Preferably, the stirring device includes a stirring barrel and several groups of stirring rods arranged in the stirring barrel, wherein the stirring rods are provided with blades, wherein a group of stirring rods is composed of two stirring rods arranged horizontally and tilted relative to each other, the number of the stirring rod groups is at least one group, and also includes a motor arranged outside the stirring barrel and connected to the stirring barrel.

[0010] There are several groups of stirring rods in the mixing barrel. The stirring rods are arranged horizontally and tilted. Two stirring rods are arranged relatively tilted to form a group of stirring rods. When the bacterial fertilizer falls into the mixing barrel and falls onto the stirring rods, the length of the two stirring rods must ensure that the bacterial fertilizer can fall onto the stirring rods after falling into the mixing barrel. The motor drives the stirring rods to rotate axially to stir the bacterial fertilizer.

[0011] Preferably, the first-level screening device includes a first box body and a crushing rod, a first filter screen and a horizontally reciprocating electric telescopic rod inside the first box body; a first feed port is opened on the top of the first box body, the first feed port is connected to the first conveyor belt, the crushing rod is horizontally fixed below the first feed port, and is driven by a motor located outside the first box body; the first filter screen is horizontally fixed below the crushing rod, and also includes a second discharge port, which is connected to the second conveyor belt.

[0012] The primary bacterial fertilizer is transported to the first-level screening device through the first conveyor belt, enters the first box in the first-level screening device, is first crushed by the crushing rod, and the crushed bacterial fertilizer falls onto the first filter net. The filtered bacterial fertilizer falls to the bottom of the first box. An electric telescopic rod is provided on the side of the bottom of the first box away from the second discharge port. The electric telescopic rod pushes the bacterial fertilizer that falls into the bottom of the first box horizontally to the second discharge port, and then pushes it to the second conveyor belt for transportation to the secondary screening device.

[0013] Preferably, the electric telescopic rod is arranged on one side inside the first box body and is connected to a push plate, and the push plate is facing the second discharge port.

[0014] Preferably, it also includes a first discharge port and a first baffle. The first discharge port is located at the bottom of the first box body, and one side of the first baffle is rotatably connected to the bottom of the first box body. It also includes a fixing part fixedly arranged at the bottom of the first box body. When the first baffle rotates to seal the first discharge port, the fixing part fixes the first baffle.

[0015] If the bacterial fertilizer particles meet the requirements after the first-level screening, they will not enter the second-level screening. At this time, the bacterial fertilizer in the first box needs to be taken out of the first box. At this time, a first discharge port is set at the bottom of the first box, and a first baffle is provided at the first discharge port. One side of the first baffle is rotatably connected to the first box, and the other side is fixed to it by a fixing member set on the outer wall of the first box. The fixing member includes but is not limited to a common door latch structure and a rotary lock.

[0016] Preferably, it further comprises a plurality of baffles obliquely arranged at the fourth discharge port.

[0017] Setting a baffle at this location can slow down the speed at which the bacterial fertilizer falls into the mixing barrel, making it fall more slowly and the mixing and drying more thorough.

[0018] Preferably, the stirring rods are hinged to the inner wall of the stirring barrel, and there are four stirring rods, which are divided into two groups and arranged on both sides of the inside of the stirring barrel and tilted downward.

[0019] Preferably, a drying device is fixedly installed on the top of the mixing barrel, and the drying device is an electric heating wire; a second baffle is also provided at the bottom of the mixing barrel, and when the second baffle is closed, the fixing method of the second baffle and the outer wall of the bottom of the mixing barrel is the same as the fixing method of the first baffle and the first box body.

[0020] When the second baffle closes the fifth discharge port, it is secured to the bottom of the mixing barrel in the same manner as the first baffle is secured to the first housing. One side of the second baffle is pivotally connected to one side of the bottom of the mixing barrel, and the other side is secured to the bottom of the mixing barrel by a fixing member disposed on the outer side wall of the bottom of the mixing barrel. Such fixing member may include, but is not limited to, a common door latch structure and a rotary lock. The biofertilizer that falls into the mixing barrel is then agitated by a motor driven by a stirring rod outside the mixing barrel to achieve a more uniform mixture. A drying device is then installed on the top to dry and heat the biofertilizer while stirring it, preventing it from becoming damp and deteriorating.

[0021] The advantage of this utility model is that two screening barrels are set. For the bacterial fertilizer that only needs simple screening, a single screening can be performed. For the bacterial fertilizer that needs multiple screenings, it is directly sent to the second screening barrel through the second conveyor belt for multiple screenings and can be dried. The device is reasonable, which not only solves the problem that the microbial fertilizer particles are piled up together and the screening is not sufficient, but also solves the problem that the biological fertilizer is wet and needs to be dried.
