[0009] Preferably, the wedge-shaped member includes a wedge-shaped block, a connecting rod and a pressure spring. A receiving groove is provided on the movable plate.

[0011] Preferably, the method for using the pellet feed hardness testing machine comprises the following steps:

[0012] S1: When testing the hardness of feed particles, a single particle is unloaded onto the arc-shaped testing plate through the unloading slide. When the feed particles fall into the groove of the arc-shaped testing plate, the testing frame on the testing device will test their hardness. When the feed particles are under pressure, fine particles will be produced. These particles will fall from the screening holes into the receiving box. This can remove impurities produced after the hardness test and avoid interference with subsequent feed particle testing. At the same time, an elastic connecting cloth is provided to prevent impurities from falling outside the receiving box and keep the equipment operating environment clean.

[0013] S2: When the feed particles are located in the grooves on the arc detection plate, the drive motor will rotate the lead screw to move the sliding plate on the support frame toward the arc detection plate. As the sliding plate moves, the two sets of articulated frames will also rotate the detection frame on the support frame. Since the detection frame is tilted, when it contacts the feed particles, the gap gradually becomes smaller, thereby increasing the pressure on the feed particles. As the detection frame deflects, when its surface is parallel to the support frame, the operator can observe the deformation of the feed particles after being compressed. When the feed particles are broken, they fall directly through the screening holes on the arc detection plate. When the feed particles are not broken, they need to continue to be tested, and the sliding plate will continue to move toward the detection device. The detection frame moves in the direction of the support frame, causing the detection frame to deflect, and the lower side of the detection frame contacts the feed particles, thereby gradually increasing the pressure on the feed particles. This setting can be used to detect the hardness of feed particles. The pressure on the feed particles is controlled by adjusting the gap between the detection frame and the feed particles. Compared with directly pressing the feed particles, this setting can more intuitively detect the hardness changes of the feed particles. When the surface of the detection frame is parallel to the support frame, the operator can intuitively observe the deformation of the compressed feed particles. In addition, the detection frame adopts segmented detection, which makes the feed particle detection data more accurate, and the pressure on the detection frame when in contact with the feed particles can be reflected from the pressure sensor;

[0014] S3: When the detection frame and the support frame are parallel, the feed particles have been broken, and the impurities in the feed particles will be screened out from the screening holes. When the detection frame and the support frame are parallel, the feed particles have not been broken, and the sliding plate continues to move and contact with the resistance rod, so that the wedge block drives the connecting rod to move in the receiving groove, so that the sliding plate can move smoothly toward the arc detection plate, and will not hinder the detection of the hardness of the feed particles by the detection frame. When the feed particles are broken after the enhanced hardness test, they will fall from the screening holes. When the feed particles are not pressed to break, they cannot fall through the screening holes. The feed particles on the arc detection plate will affect the hardness test of the next group of feeds. At this time, the screw will drive the sliding plate to return to the initial position. When the sliding plate moves, the resistance rod will contact the surface of the wedge block, driving the wedge to slide in the dovetail groove. When the sliding plate returns to the initial position When the slider is in position, the wedge block will contact the wedge frame, thereby driving the connecting rod to move in the moving plate. At this time, the resisting spring is under pressure, pushing the moving plate toward the detection device, and the moving plate quickly moves in the dovetail groove, contacts the elastic telescopic rod to cause it to shrink, and the contact frame on the moving plate will contact the rotating wheel, thereby driving the rotating wheel to rotate, pressing the positioning frame downward, and then tilting the arc-shaped detection plate, pouring out the remaining feed particles, screening out the remaining parts for the detection personnel to observe, when the sliding plate contacts the elastic telescopic rod, the elastic telescopic rod will gradually return to its original state, under the action of the connecting spring, the arc-shaped detection plate will return to a parallel state, and continue to cooperate with the detection device to detect the feed. This setting can speed up the detection efficiency of feed particles, while gradually screening out feed particles, improving the accuracy of feed particle hardness detection, and facilitating observation by operators.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, when testing the hardness of feed particles, a single particle is unloaded onto the arc-shaped detection plate through a unloading slide. When the feed particles fall into the groove of the arc-shaped detection plate, the detection frame on the detection device will perform a hardness test on them. When the feed particles are subjected to pressure, fine particles will be generated, and these particles will fall from the screening holes into the receiving box. This can remove impurities generated after the hardness test and avoid interference with subsequent feed particle detection. At the same time, an elastic connecting cloth is provided to prevent impurities from falling to the outside of the receiving box and keep the equipment operating environment clean and tidy.

[0017] In the present invention, when the feed particles are located in the grooves on the arc-shaped detection plate, the driving motor will rotate the screw rod to move the sliding plate on the support frame toward the direction of the arc-shaped detection plate. As the sliding plate moves, the two sets of hinged frames will also rotate the detection frame on the support frame. Since the detection frame is arranged at an angle, when it contacts the feed particles, the gap gradually becomes smaller, thereby increasing the pressure on the feed particles. As the detection frame deflects, when its surface is parallel to the support frame, the operator can observe the deformation of the feed particles after being compressed. When the feed particles are broken, they fall directly through the screening holes on the arc-shaped detection plate. When the feed particles are not broken, they need to continue to be detected, and the sliding plate will continue to move toward the detection device. The detection frame moves in the direction of the setting, causing the detection frame to deflect, and the lower side of the detection frame contacts the feed particles, thereby gradually increasing the pressure on the feed particles. This setting can be used to detect the hardness of feed particles. The pressure of the feed particles is controlled by adjusting the gap between the detection frame and the feed particles. Compared with directly pressing the feed particles, this setting can more intuitively detect the hardness changes of the feed particles. When the surface of the detection frame is parallel to the support frame, the operator can intuitively observe the deformation of the compressed feed particles. In addition, the detection frame adopts segmented detection, which makes the feed particle detection data more accurate, and the pressure on the detection frame in contact with the feed particles can be reflected from the pressure sensor.

[0018] In the present invention, when the detection frame and the support frame are parallel, the feed particles have been broken, and the impurities in the feed particles will be screened out from the screening holes. When the detection frame and the support frame are parallel, the feed particles have not been broken, and the sliding plate continues to move and contact with the resistance rod, so that the wedge block drives the connecting rod to move in the accommodating groove, so that the sliding plate can smoothly move toward the arc-shaped detection plate, and will not hinder the detection of the hardness of the feed particles by the detection frame. When the feed particles are broken after the enhanced hardness test, they will fall from the screening holes. When the feed particles are not pressed to be broken, they cannot fall through the screening holes. The feed particles on the arc-shaped detection plate will affect the hardness test of the next group of feeds. At this time, the screw rod will drive the sliding plate to return to its initial position. When the sliding plate moves, the resistance rod will contact the surface of the wedge block, driving the wedge to slide in the dovetail groove. When the sliding plate returns to its initial position, the resistance rod will contact the surface of the wedge block, driving the wedge to slide in the dovetail groove. When the slider is in the correct position, the wedge block will contact the wedge frame, thereby driving the connecting rod to move in the moving plate. At this time, the resistance spring is under pressure, pushing the moving plate toward the detection device, and the moving plate quickly moves in the dovetail groove, contacting the elastic telescopic rod to cause it to contract, and the contact frame on the moving plate will contact the rotating wheel, thereby driving the rotating wheel to rotate, pressing the positioning frame downward, and then tilting the arc-shaped detection plate, pouring out the remaining feed particles, screening out the remaining parts for the detection personnel to observe, and when the sliding plate contacts the elastic telescopic rod, the elastic telescopic rod will gradually return to its original state, and under the action of the connecting spring, the arc-shaped detection plate will return to a parallel state and continue to cooperate with the detection device to detect the feed. This setting can speed up the detection efficiency of feed particles, while gradually screening out feed particles, improving the accuracy of feed particle hardness detection, and facilitating observation by operators.

As the sliding plate 34 moves, the two sets of hinged frames 36 will also rotate the detection frame 35 on the support frame 31. Since the detection frame 35 is tilted, when it contacts the feed particles, the gap gradually becomes smaller, thereby increasing the pressure on the feed particles.

The arc-shaped detection plate 44 is located below the detection frame 35, and the unloading slide 2 is located beside the arc-shaped detection plate 44;

[0035] When testing the hardness of feed particles, a single particle is unloaded onto the arc-shaped detection plate 44 through the unloading slide 2. When the feed particles fall into the groove 442 of the arc-shaped detection plate 44, the detection frame 35 on the detection device 3 will perform a hardness test on them. When the feed particles are subjected to pressure, fine particles will be generated, and these particles will fall from the screening holes 441 into the receiving box 41. This can remove impurities generated after the hardness test and avoid interference with subsequent feed particle detection. At the same time, an elastic connecting cloth 42 is provided to prevent impurities from falling to the outside of the receiving box 41 and keep the equipment operating environment clean.

[0036] In this embodiment, Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the support frame 31 is also provided with an auxiliary transmission member 5, and the auxiliary transmission member 5 includes a resistance rod 51, a movable plate 52, a resistance spring 53, a wedge frame 54, an elastic telescopic rod 55 and a wedge member 6. The resistance rod 51 is fixedly arranged on the sliding plate 34, and a dovetail groove 311 is provided on the support frame 31. The wedge member 6 is arranged in the dovetail groove 311 on the support frame 31 and slidably cooperates with the dovetail groove 311. The resistance rod 51 contacts the wedge member 6 to drive the wedge member 6 to move in the dovetail groove 311. The wedge frame 54 is fixedly arranged on the support frame 31 and contacts the wedge member 6. The two ends of the resistance spring 53 are respectively connected to the support frame 31 and the movable plate 52. The elastic telescopic rod 55 is fixedly arranged on the support frame 31 and contacts the movable plate 52.

[0037] The wedge-shaped member 6 includes a wedge-shaped block 61, a connecting rod 62 and a pressure spring 63. A receiving groove is provided on the movable plate 52.

The pressure spring 63 is sleeved on the connecting rod 62 and is located in the receiving groove. The two ends of the pressure spring 63 are respectively connected to the inner wall of the receiving groove on the movable plate 52 and the connecting rod 62.

[0039] When the detection frame 35 and the support frame 31 are parallel, the feed particles have been broken, and the impurities in the feed particles will be screened out from the screening holes 441. When the detection frame 35 and the support frame 31 are parallel, the feed particles have not been broken, and the sliding plate 34 continues to move and contacts the abutment rod 51, so that the wedge-shaped block 61 drives the connecting rod 62 to move in the receiving groove, so that the sliding plate 34 moves smoothly toward the arc-shaped detection plate 44, which will not hinder the detection frame 35 from detecting the hardness of the feed particles.

This setting can speed up the detection efficiency of the feed particles, and at the same time, the feed particles will be gradually screened out, thereby improving the accuracy of the feed particle hardness detection and facilitating the observation of the operator.

[0040] The use method and advantages of the present invention: The use method of the pellet feed hardness testing machine, the working process is as follows:

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown:

[0042] S1: When testing the hardness of feed particles, a single particle is fed onto the arc-shaped testing plate 44 through the feeding slide 2. When the feed particles fall into the groove 442 of the arc-shaped testing plate 44, the testing frame 35 on the testing device 3 will perform a hardness test on them. When the feed particles are subjected to pressure, fine particles will be generated, and these particles will fall from the screening holes 441 into the receiving box 41. In this way, impurities generated after the hardness test can be removed to avoid interference with subsequent feed particle testing. At the same time, an elastic connecting cloth 42 is provided to prevent impurities from falling outside the receiving box 41, so as to keep the equipment operating environment clean and tidy.

[0043] S2: When the feed particles are located in the groove 442 on the arc detection plate 44, the driving motor 32 will rotate the screw rod 33 to move the sliding plate 34 on the support frame 31 in the direction of the arc detection plate 44. As the sliding plate 34 moves, the two sets of hinged frames 36 will also rotate the detection frame 35 on the support frame 31. Since the detection frame 35 is tilted, when it contacts the feed particles, the gap gradually becomes smaller, thereby increasing the pressure on the feed particles. As the detection frame 35 deflects, when its surface is parallel to the support frame 31, the operator can observe the deformation of the feed particles after being compressed. When the feed particles are broken, they fall directly through the screening holes 441 on the arc detection plate 44. When the feed particles are not broken, it is necessary to continue testing. The sliding frame 36 will move the detection frame 35 to the support frame 31. The plate 34 will continue to move toward the detection device 3, causing the detection frame 35 to deflect, and the lower side of the detection frame 35 will contact the feed particles, thereby gradually increasing the pressure on the feed particles. This setting can be used to detect the hardness of the feed particles. The pressure on the feed particles can be controlled by adjusting the gap between the detection frame 35 and the feed particles. Compared with directly pressing the feed particles, this setting can more intuitively detect the hardness change of the feed particles. When the surface of the detection frame 35 is parallel to the support frame 31, the operator can intuitively observe the deformation of the compressed feed particles. In addition, the detection frame 35 adopts segmented detection, which makes the feed particle detection data more accurate, and the pressure on the detection frame 35 when in contact with the feed particles can be reflected from the pressure sensor;

[0044] S3: When the detection frame 35 and the support frame 31 are parallel, the feed particles have been broken, and the impurities in the feed particles will be screened out from the screening holes 441. When the detection frame 35 and the support frame 31 are parallel, the feed particles have not been broken, and the sliding plate 34 continues to move and contacts the abutment rod 51, so that the wedge block 61 drives the connecting rod 62 to move in the receiving groove, so that the sliding plate 34 moves smoothly toward the arc detection plate 44, which will not hinder the detection frame 35 from detecting the hardness of the feed particles. After the feed particles are crushed by the enhanced hardness test, they will fall from the screening hole 441. When the feed particles are not crushed, they cannot fall through the screening hole 441. The feed particles on the arc detection plate 44 will affect the hardness test of the next group of feed. At this time, the screw rod 33 will drive the sliding plate 34 to return to the initial position. When the sliding plate 34 moves, the resistance rod 51 will contact the surface of the wedge block 61, driving the wedge piece 6 to slide in the dovetail groove 311. When the sliding plate 34 returns to the initial position, the friction rod 51 will contact the surface of the wedge block 61, driving the wedge piece 6 to slide in the dovetail groove 311. When it reaches the initial position, the wedge block 61 will contact the wedge frame 54, thereby driving the connecting rod 62 to move in the movable plate 52. At this time, the resistance spring 53 is under pressure, pushing the movable plate 52 toward the detection device 3, and the movable plate 52 quickly moves in the dovetail groove 311, contacts the elastic telescopic rod 55 to shrink it, and the contact frame 7 on the movable plate 52 will contact the rotating wheel 74, thereby driving the rotating wheel 74 to rotate, so that the positioning frame 72 is pressed down, and then the arc detection plate 44 is tilted, and the remaining feed particles are poured out, and the remaining part is screened out for observation by the detection personnel. When the sliding plate 34 contacts the elastic telescopic rod 55, the elastic telescopic rod 55 will gradually return to its original state. Under the action of the connecting spring 73, the arc detection plate 44 will return to a parallel state and continue to cooperate with the detection device 3 to detect the feed. This setting can speed up the detection efficiency of feed particles, and at the same time, the feed particles are gradually screened out, so as to improve the accuracy of the feed particle hardness detection and facilitate the observation of the operator.

5. A method for using a pellet feed hardness testing machine, comprising the following steps: S1: When testing the hardness of feed particles, a single particle is fed onto the arc-shaped testing plate (44) through the feeding slide (2). When the feed particle falls into the groove (442) of the arc-shaped testing plate (44), the testing frame (35) on the testing device (3) will test its hardness. If the feed particle is subjected to pressure, fine particles will be generated. These particles will fall from the screening holes (441) into the receiving box (41). At the same time, an elastic connecting cloth (42) is provided to prevent impurities from falling outside the receiving box (41), thereby keeping the equipment operating environment clean and tidy. S2: When the feed particles are located in the grooves (442) on the arc-shaped detection plate (44), the drive motor (32) causes the screw rod (33) to rotate and moves the sliding plate (34) on the support frame (31) in the direction of the arc-shaped detection plate (44). As the sliding plate (34) moves, the two sets of hinged frames (36) also cause the detection frame (35) to rotate on the support frame (31). Since the detection frame (35) is inclined, when it contacts the feed particles, the gap gradually becomes smaller, increasing the pressure on the feed particles. As the detection frame (35) deflects, when its surface When the slide plate (34) is parallel to the support frame (31), the operator can observe the deformation of the feed particles after being pressed. If the feed particles are broken, they will fall directly through the screening holes (441) on the arc-shaped detection plate (44). If the feed particles are not broken, it is necessary to continue the detection. The sliding plate (34) will continue to move in the direction of the detection device (3), causing the detection frame (35) to deflect. The lower side of the detection frame (35) contacts the feed particles, thereby gradually increasing the pressure on the feed particles. The pressure on the detection frame (35) in contact with the feed particles can be reflected by the pressure sensor. S3: When the detection frame (35) and the support frame (31) are parallel, the feed particles have been broken, and the impurities in the feed particles will be screened out from the screening holes (441). When the detection frame (35) and the support frame (31) are parallel, the feed particles have not been broken, and the sliding plate (34) continues to move and contacts the abutment rod (51), so that the wedge block (61) drives the connecting rod (62) to move in the receiving groove, so that the sliding plate (34) moves smoothly toward the arc-shaped detection plate (44), and will not hinder the detection frame (35) from detecting the hardness of the feed particles. If the feed particles are broken after the enhanced hardness test, they will fall from the screening holes (441). If the feed particles are not pressed to be broken, they will not be able to fall through the screening holes (441). The feed particles on the arc-shaped detection plate (44) will affect the hardness test of the next group of feed. At this time, the screw rod (33) will drive the sliding plate When the sliding plate (34) is restored to its initial position, when the sliding plate (34) moves, the abutment rod (51) contacts the surface of the wedge-shaped block (61), driving the wedge-shaped member (6) to slide in the dovetail groove (311). When the sliding plate (34) returns to its initial position, the wedge-shaped block (61) contacts the wedge-shaped frame (54), thereby driving the connecting rod (62) to move in the moving plate (52). At this time, the abutment spring (53) is subjected to pressure, pushing the moving plate (52) toward the detection device (3). The moving plate (52) quickly moves in the dovetail groove (311), contacts the elastic telescopic rod (55) to shrink it, and the contact frame (7) on the moving plate (52) contacts the rotating wheel (74), thereby driving the rotating wheel (74) to rotate, pressing the positioning frame (72) downward, and then tilting the arc-shaped detection plate (44), pouring out the remaining feed particles, and screening out the remaining part for observation by the detection personnel.
