DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0028] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0029] Embodiment: A screening machine for humic acid production, see attached Figure 1 -Attached Figure 3 , comprising a screen 1, a collecting hopper 3 and a transmission line 4, wherein the screen 1 is arranged obliquely, the inclined top end of the screen 1 is a feeding end, and the inclined bottom end is a discharging end; the collecting hopper 3 is used to collect the large-particle humic acid sent out by the screen 1; the transmission line 4 is used to transport the humic acid collected by the collecting hopper 3 to the pulverizer 2. The pulverizer 2 is arranged above the feeding end of the screen 1, and the transmission line 4 transports the large-particle humic acid collected by the collecting hopper 3 to the pulverizer 2.

[0030] The pulverizer 2 pulverizes the dried humic acid, and the pulverized humic acid falls to the feed end of the screen 1, and rolls downward along the inclination direction of the screen 1 under the action of its own gravity. In the process of rolling downward, the humic acid particles that meet the specifications pass through the screen 1 and fall down, while the large-particle humic acid that does not meet the specifications cannot pass through the screen 1, so that the large-particle humic acid rolls out from the discharge end of the screen 1 and enters the collecting hopper 3. The collecting hopper 3 collects the large-particle humic acid and transports the large-particle humic acid to the pulverizer 2 through the transmission line 4 to pulverize the humic acid again, without the need for manual collection of the large-particle humic acid on the screen 1.

[0031] Specifically, the transmission line 4 includes a horizontal auger 41 and an inclined auger 42. The horizontal auger 41 is arranged at the bottom of the collecting hopper 3 to transport large-particle humic acid to a place near the crusher 2; the feed end of the inclined auger 42 is located at the bottom of the discharge end of the horizontal auger 41, and the discharge end of the inclined auger 42 is connected to the crusher 2.

[0032] By setting the horizontal auger 41 and the inclined auger 42, the large-particle humic acid can be smoothly transported and lifted to the feed point of the pulverizer 2, so that the large-particle humic acid can smoothly enter the pulverizer 2 for re-pulverization.

[0033] Specifically, the present embodiment further includes a baffle plate 11 and a discharge plate 5, wherein the baffle plate 11 surrounds both sides and the top end of the screen 1; the discharge plate 5 is fixedly connected to the discharge end of the screen 1 and is flush with the screen 1, the width of the discharge plate 5 gradually decreases along the downward inclination of the screen 1, and two guide plates 51 are fixedly connected to both sides of the discharge plate 5; the collecting hopper 3 is arranged below the end of the discharge plate 5 away from the screen 1. Through the arrangement of the discharge plate 5 and the guide plate 51, after the large-particle humic acid enters the discharge plate 5, it can be retracted to the middle position of the discharge plate 5 away from the end of the screen 1 under the action of the two guide plates 51, so that the large-particle humic acid can fall into the collecting hopper 3.

[0034] Specifically, a discharge pipe 31 is fixedly connected to the bottom of the collecting hopper 3, and a solenoid valve 32 for controlling the switch of the discharge pipe 31 is provided on the discharge pipe 31. The discharge pipe 31 is used to deliver the material to the horizontal auger 41; a weight sensor 36 is provided below the collecting hopper 3, and the weight sensor 36 is used to detect the weight of the collecting hopper 3 and the material in the collecting hopper 3, and the weight sensor 36 is electrically connected to the solenoid valve 32.

[0035] The large particles of humic acid on the screen 1 fall into the collecting hopper 3. When the humic acid is screened, the content of large particles of humic acid is small, so the amount of large particles of humic acid entering the collecting hopper 3 in a short time is small. If the horizontal auger 41 and the inclined auger 42 are kept in motion, it will cause a waste of energy. In this embodiment, a weight sensor 36 and a solenoid valve 32 are set. When the solenoid valve 32 is closed, the horizontal auger 41 and the inclined auger 42 stop working and enter the collecting hopper. 3 is stored in the aggregate hopper 3. When the humic acid in the aggregate hopper 3 reaches a certain amount, the weight sensor 36 detects that the weight of the aggregate hopper 3 and the humic acid in the aggregate hopper 3 reaches the requirement, the solenoid valve 32 opens, and the humic acid in the aggregate hopper 3 falls to the feeding end of the horizontal auger 41. Then the horizontal auger 41 and the inclined auger 42 start to work to transport the humic acid in the aggregate hopper 3 to the crusher 2. When the humic acid in the aggregate hopper 3 is transported, the solenoid valve 32 is closed.

[0036] Specifically, a plurality of vertically arranged vertical rods 34 are fixedly connected to the collecting hopper 3 , and a support plate 35 located below the horizontal auger 41 is fixedly connected to the bottom of the vertical rods 34 , and the support plate 35 is supported on the top of the weight sensor 36 .

[0037] Specifically, the bottom of the discharge pipe 31 is fixedly connected with a flexible tube 33 , and one end of the bottom of the flexible tube 33 is fixedly connected to the top of the feeding end of the horizontal auger 41 .

[0038] Specifically, a collecting box 6 for collecting humic acid is arranged below the screen 1, and the top of the collecting box 6 is open; a guide box 12 is arranged at the bottom of the screen 1 and passes through the bottom. The guide box 12 is supported above the collecting box 6 by an elastic member 15, and a vibration motor is fixedly connected to the guide box 12.

[0039] Specifically, two side plates 13 are fixedly connected on both sides of the guide box 12, and each side plate 13 is provided with two guide rods 14 vertically penetrating the side plates 13. The side plates 13 can slide vertically on the two guide rods 14, and the bottom of the guide rods 14 is fixedly connected to the top of the collection box 6; the elastic member 15 is configured as a spring, and a spring is sleeved on the outside of each guide rod 14, and the bottom end and the top end of the spring are respectively pressed against the top of the collection box 6 and the bottom of the side plate 13.

[0040] By providing the vibration motor and the elastic member 15 , the humic acid on the screen 1 can be vibrated, so that the particles in the humic acid that meet the specifications can pass through the screen 1 more smoothly and enter the collection box 6 .

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
