Description

Technical Field

[0001] This utility model relates to the field of feed processing, specifically to a screw conveyor-type powdering rate measuring device. Background Technology

[0002] Powdering rate refers to the percentage of feed pellets broken into powder out of the total weight. For most animals, feed powder cannot be fully consumed, and the powder accumulating in the feed trough increases feed and management costs while also posing a risk of spoilage. Therefore, powdering rate is an important indicator of pellet processing quality. Most existing pelleting rate measuring devices first measure the total weight of a sample feed of one type of pellet, then place the sample feed into a powdering device to simulate the external forces experienced during pellet production, transportation, and conveying. This simulates some pellets turning into powder. The pellets and powder are then separated, and the weight of the separated powder is weighed to calculate the powder percentage. However, the simulated external forces experienced by existing devices during pellet production, transportation, and conveying are not ideal, affecting the final measurement result of the powdering rate.

[0003] Currently, due to the widespread use of feed transport tankers and mechanized farming, augers have become the most commonly used feed delivery method at both the transportation and feeding ends. Although the use of augers has accelerated transportation and feeding efficiency and saved manpower and resources, their existence has also greatly increased the proportion of powder in pelleted feed during transportation and feeding.

[0004] The common method for testing the pulverization rate of pelleted feed involves placing a unit weight of pelleted feed in a testing device, sieving the sample, and calculating the percentage of powdery feed by weight. Existing methods for determining pulverization rate fall into two main categories. One type uses a repetitive mechanical force, such as: rotary type, which uses a single reciprocating rotational force to make the feed pellets rotate inside the machine, impacting baffles and thus producing powder; blown type, which uses air to blow the feed up and impact the internal baffles of the pulverizer, causing the feed to break down and produce powder; and oscillating type, which uses reciprocating vibration to make the feed impact the inner wall of the machine or collide with each other, causing the feed to break down and produce powder. These pulverizers all use a single external force to simulate the external forces experienced during production, transportation, and conveying. However, a single, repetitive mechanical force cannot fully simulate all possible damage to the pellets from production to animal consumption, resulting in low data reliability and an inability to obtain a pulverization rate that closely approximates the actual situation after the feed leaves the factory. Utility Model Content

[0005] The purpose of this invention is to solve the above problems and provide a screw conveyor-type pulverization rate measuring device. By setting two interconnected screw conveyors, the feed particles are continuously circulated within them, which can completely reproduce the damage of feed particles in the screw conveyor during production, transportation and conveying. The actual pulverization rate data of the long screw conveyor can be obtained in a small space.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A screw conveyor-type pulverization rate measuring device includes a frame, a lifting screw conveyor and a feeding screw conveyor arranged intersectingly within the frame, and a vibrating screen disposed at the bottom of the frame. The lower end of the lifting screw conveyor is provided with a material inlet, and the lower end of the feeding screw conveyor is provided with a tee. One outlet of the tee is connected to the lower end of the feeding screw conveyor, and the other outlet of the tee is connected to the vibrating screen. The inlet of the tee is connected to the discharge port at the upper end of the lifting screw conveyor, and the discharge port at the upper end of the lifting screw conveyor is connected to the material inlet at the lower end of the lifting screw conveyor.

[0008] Furthermore, the vibrating screen is provided with two discharge ports at its lower end, and the two discharge ports correspond to two receiving boxes respectively.

[0009] Furthermore, the receiving boxes are respectively a particle receiving box and a powder receiving box, and the vibrating screen is inclined downward from the powder receiving box to the particle receiving box.

[0010] Furthermore, a weighing device is provided at the lower end of the receiving box.

[0011] Furthermore, both the lower end of the lifting auger and the lower end of the feeding auger are equipped with opening and closing doors.

[0012] Furthermore, the tilt angle of the lifting auger is 10° to 45°.

[0013] Furthermore, the inclination angle of the feeding auger is 0° to 15°.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model includes a frame, a lifting auger and a feeding auger arranged intersectingly within the frame, and a vibrating screen located at the bottom of the frame. The lower end of the lifting auger has a material inlet, and the lower end of the feeding auger has a T-junction. One outlet of the T-junction connects to the lower end of the feeding auger, and the other outlet corresponds to the vibrating screen. The inlet of the T-junction connects to the discharge port at the upper end of the lifting auger, and the discharge port at the upper end of the lifting auger connects to the material inlet at the lower end of the lifting auger. The feed pellets circulate continuously within the two interconnected augers, completely replicating the damage to the feed pellets during production, transportation, and conveying. This allows for obtaining actual pulverization rate data for a long auger in a relatively small space, rather than simulated data.

[0016] 2. It is relatively small in size, lightweight, and easy to move.

[0017] 3. The running time can be set to simulate augers of different lengths, thus obtaining real auger pulverization data, rather than simulated data. Attached Figure Description

[0023] like Figure 1 and Figure 2As shown, a screw conveyor-type pulverization rate measuring device includes a frame 1, a lifting screw conveyor 2 and a feeding screw conveyor 3 arranged intersectingly within the frame 1, and a vibrating screen 6 located at the bottom of the frame 1. The lifting screw conveyor 2 and the feeding screw conveyor 3 are both fixed to the frame by bolts. The lower end of the lifting screw conveyor 2 is provided with a material inlet 4, which is connected to the lower end of the lifting screw conveyor 2. The material inlet 4 is connected to a feed trough via a flexible hose, and the material in the feed trough enters the lifting screw conveyor 2 through the material inlet 4. The lower end of the feeding screw conveyor 3 is provided with a tee 5, one outlet of which is connected to the lower end of the feeding screw conveyor 3, and the other outlet of the tee 5 is connected to the vibrating screen 6. When the screw conveyor operation time is reached, it turns to the open state, and the material in the diversion funnel does not enter the feeding screw conveyor but enters the vibrating screen. The inlet of the tee 5 is connected to the discharge port at the upper end of the lifting screw conveyor 2, and the discharge port at the upper end of the lifting screw conveyor 2 is connected to the material inlet 4 at the lower end of the lifting screw conveyor 2. By using two interconnected augers to continuously circulate feed pellets, the system can completely replicate the pellet damage that occurs during production, transportation, and conveying. It provides actual auger pulverization rate data for long augers within a relatively small space, rather than simulated data. It is compact, lightweight, and easy to move. The operating time can be set to simulate augers of different lengths, thus obtaining real auger pulverization data, not simulated data.

[0024] A screw conveyor drive motor is located on one side of the auger. The auger drive motor is electrically connected to a speed controller. The speed controller precisely regulates the speed of the auger drive motor according to a preset control program, which is stored in a controller connected to the speed controller. The motor is equipped with a speed reducer, which is connected to the auger. The controller is electrically connected to the main display.

[0025] like Figure 2 As shown, the vibrating screen 6 has two discharge ports 7 at its lower end, and the two discharge ports correspond to two receiving boxes 8 respectively.

[0026] like Figure 2 As shown, the receiving box 8 is divided into a particle receiving box and a powder receiving box. The vibrating screen 6 is inclined downward from the powder receiving box to the particle receiving box. When the vibrating screen 6 vibrates, the material is screened on the vibrating screen 6. The powder falls into the powder receiving box first, and the particles enter the particle receiving box after being screened.

[0027] like Figure 2 As shown, a weighing device 9 is provided at the lower end of the receiving box 8. There are two weighing devices 9, and each weighing device 9 corresponds to one of the two receiving boxes.

[0028] like Figure 2 As shown, both the lower end of the lifting auger 2 and the lower end of the feeding auger 3 are equipped with a switch door 10. During operation, the switch door 10 is in the closed state, and when the operation stops, it can be used to clean up the material.

[0029] The tilt angle of the lifting auger 2 is 10° to 45°.

[0030] The inclination angle of the feeding auger 3 is 0° to 15°.
