First, people place the building materials on the placing seat 3, then people start the servo motor 82, the output shaft of the servo motor 82 rotates to drive the screw rod 83 to rotate, the screw rod 83 rotates to make the connecting plate 84 move to the rear side, the connecting plate 84 moves to the rear side to drive the placing seat 3 to move to the rear side, so as to realize the effect of automatic feeding. The rear side of the second contact column 96 moves to the rear side when the last side of the second contact column 96 moves to the rear side and contacts the contact rod 93, the last side of the second contact column 96 continues to move to the rear side to push the contact rod 93 to rotate, the contact rod 93 rotates to drive the cam 92 to rotate, at this time the torsional spring 94 is twisted, the rotation of the cam 92 will make the first contact column 95 move to the upper side, the first contact column 95 moves to the upper side to drive the impact hammer 7 to move to the upper side, at this time the first return spring 6 is compressed, then when the last side of the second contact column 96 is separated from the contact rod 93, the cam 92 is reversed under the action of the torsional spring 94, the cam 92 drives the contact rod 93 to reverse, then when the cam 92 is separated from the first contact column 95, the impact hammer 7 moves downward under the action of the first return spring 6 to reset, the impact hammer 7 moves downward to drive the first contact column 95 to move downward to reset, the impact hammer 7 moves downward to impact test the building materials, then the other directions of the building materials can be intermittently and equidistantly impacted and tested, when the building material detection is completed, people control the output shaft of the servo motor 82 to reverse, so that the screw rod 83 reverses, and then the placing seat 3 moves to the front side to reset, then people turn off the servo motor 82, and take out the detected building materials, repeat the above operation to achieve the effect of automatic feeding, and the building materials can also be equidistantly detected, so as to improve the accuracy of the detection result.

[0036] As Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, it also includes the limiting mechanism 10 capable of clamping and limiting the building materials, the limiting mechanism 10 includes the connecting bracket 101, the limiting plate 102, the second reset spring 103, the connecting column 104, the wedge-shaped plate 105 and the third contact column 106, the left and right sides of the placing seat 3 are symmetrically connected with the connecting bracket 101 through bolts, the connecting column 104 is slidably connected to the connecting bracket 101, the limiting plate 102 is connected between the right sides of the two connecting columns 104 on the left side, and the limiting plate 102 is also connected between the left sides of the two connecting columns 104 on the right side, the limiting plate 102 can clamp and limit the building materials, the second reset spring 103 is connected between the limiting plate 102 and the adjacent connecting bracket 101 on the left and right sides, the second reset spring 103 can move and reset the limiting plate 102, the second reset spring 103 is wound around the surface of the connecting column 104, the wedge-shaped plate 105 is connected between the left sides of the two connecting columns 104 on the left side, and the wedge-shaped plate 105 is also connected between the right sides of the two connecting columns 104 on the right side, the third contact column 106 is bolted to the left and right sides of the front inner wall of the protective cover 4, and the third contact column 106 can move the wedge-shaped plates 105 close to each other.

[0037] When people need to clamp and limit the building materials, first, when the placing seat 3 moves to the rear side, the placing seat 3 moves to the rear side and drives the wedge-shaped plate 105, the connecting column 104 and the limiting plate 102 to move to the rear side, when the wedge-shaped plate 105 contacts the third contact column 106, the wedge-shaped plate 105 continues to move to the rear side and is pressed by the third contact column 106, then the wedge-shaped plate 105 moves close to each other, the wedge-shaped plate 105 moves close to each other drives the connecting column 104 and the limiting plate 102 to move close to each other, at this time, the second reset spring 103 is stretched, the limiting plate 102 can clamp and limit the building materials, then people can detect the building materials, after detection, when the placing seat 3 moves to the front side and resets, the placing seat 3 moves to the front side and drives the wedge-shaped plate 105, the connecting column 104 and the limiting plate 102 to move to the front side and reset, when the wedge-shaped plate 105 is separated from the third contact column 106, the limiting plate 102 moves away from each other under the action of the second reset spring 103, the limiting plate 102 moves away from each other drives the connecting column 104 and the wedge-shaped plate 105 to move away from each other, repeating the above operation can clamp and limit the building materials, thereby preventing the building materials from moving during detection.

[0038] As Figure 1 , Figure 2 , Figure 11 and Figure 12As shown, the protective mechanism 11 is also included, which can prevent people from being injured when the building materials are broken. The protective mechanism 11 includes guide posts 111, connecting rods 112, third return springs 113, arc-shaped protective plates 114, wedge-shaped blocks 115, and fourth contact posts 116. Two guide posts 111 are welded on the left and right sides of the front inner wall of the protective cover 4. The two guide posts 111 on the left side are slidably connected with a connecting rod 112. The two guide posts 111 on the right side are also slidably connected with a connecting rod 112. The guide posts 111 can guide the connecting rods 112. The third return spring 113 is connected between the left side of the front part of the connecting rod 112 and the left front guide post 111. The third return spring 113 is also connected between the left side of the rear part of the connecting rod 112 and the left rear guide post 111. The third return spring 113 is also connected between the right side of the front part of the connecting rod 112 and the right front guide post 111. The third return spring 113 is also connected between the right side of the rear part of the connecting rod 112 and the right rear guide post 111. The third return spring 113 is wound around the surface of the guide post 111. The third return spring 113 can make the connecting rod 112 move back to the original position. The arc-shaped protective plates 114 are connected to the sides of the connecting rods 112 that are close to each other. When the arc-shaped protective plates 114 are in contact, it can prevent people from being injured when the building materials are broken. The wedge-shaped blocks 115 are connected to the upper sides of the connecting rods 112. The fourth contact posts 116 are connected to the lower sides of the first contact posts 95. The fourth contact posts 116 on the left side are in contact with the wedge-shaped blocks 115 on the left side. The fourth contact posts 116 on the right side are in contact with the wedge-shaped blocks 115 on the right side.

[0039] If the building material is broken when it is detected, the debris will splash everywhere and cause people to be injured, so it needs to be protected. Initially, the third reset spring 113 is in a stretched state, and the arc-shaped protective plate 114 is in a contact closed state. First, when the first contact column 95 moves upward, the first contact column 95 moves upward, which drives the impact hammer 7 and the fourth contact column 116 to move upward. When the fourth contact column 116 is separated from the wedge block 115, the connecting rods 112 move away from each other under the action of the third reset spring 113, the guide column 111 can guide the connecting rods 112, the connecting rods 112 move away from each other, which drives the arc-shaped protective plate 114 to move away from each other. The arc-shaped protective plate 114 moves away from each other, which drives the wedge block 115 to move away from each other. Then, when the first contact column 95 moves downward and resets, it drives the impact hammer 7 to move downward to detect the building material. The first contact column 95 moves downward, which drives the fourth contact column 116 to move downward. The fourth contact column 116 moves downward, which presses the wedge block 115 to move closer to each other. The wedge block 115 moves closer to each other, which drives the connecting rods 112 and the arc-shaped protective plate 114 to move closer to each other. At this time, the third reset spring 113 is compressed, and the arc-shaped protective plate 114 moves closer to each other and is in contact closed state, which can hide the impact hammer 7. Thus, it can prevent the debris from splashing when the building material is broken during detection. Repeating the above operation can prevent the debris from splashing when the building material is broken, which can prevent people from being injured and thus protect people.

[0040] As Figure 1 and Figure 13 shown, it also includes a surface debris removal mechanism that can remove debris from the surface of the building material. The surface debris removal mechanism 12 includes a first guide bracket 121, a fourth reset spring 122, and a cleaning roller frame 123. The first guide bracket 121 is attached between the inner wall of the protective cover 4 and the left and right sides of the front part. The cleaning roller frame 123 is connected to the first guide bracket 121 in a sliding manner. The cleaning roller frame 123 can remove debris from the surface of the building material. The first guide bracket 121 can guide the cleaning roller frame 123. Three fourth reset springs 122 are connected between the cleaning roller frame 123 and the lower side of the first guide bracket. The fourth reset spring 122 can move the cleaning roller frame 123 back to its original position.

[0041] When people need to remove the debris on the surface of the building materials, first, when the placing seat 3 and the building materials move to the rear side, the building materials pass through the cleaning roller frame 123, and the cleaning roller frame 123 can remove the debris on the surface of the building materials. If the debris is thick, the cleaning roller frame 123 will move to the upper side, at this time, the fourth reset spring 122 is compressed, and then when the debris cleaning is completed, the cleaning roller frame 123 moves downward to reset under the action of the fourth reset spring 122. The above operation can remove the debris on the surface of the building materials, thereby improving the accuracy of the building material detection result.

[0042] As shown in Figure 1 , Figure 2 and Figure 14 , it also comprises a debris cleaning mechanism 13 which can clean the debris remaining on the placing seat 3. The debris cleaning mechanism 13 comprises a second guide bracket 131, a fifth reset spring 132 and a scraping plate 133. Two second guide brackets 131 are bolted on the placing seat 3, and the two second guide brackets 131 are symmetrically arranged left and right. The scraping plate 133 is slidably connected between the two second guide brackets 131. The second guide bracket 131 can guide the scraping plate 133. The scraping plate 133 can scrape the debris remaining on the placing seat 3. The fifth reset spring 132 is connected between the left front side of the scraping plate 133 and the placing seat 3. The fifth reset spring 132 is also connected between the right front side of the scraping plate 133 and the placing seat 3. The fifth reset spring 132 is wound on the surface of the second guide bracket 131. The fifth reset spring 132 can move the scraping plate 133 to reset.

[0043] As shown in Figure 14 , it also comprises a handle 134. The handle 134 is connected to the upper side of the scraping plate 133. The handle 134 facilitates the movement of the scraping plate 133.

[0044] When the building materials are broken, some debris will remain on the placing seat 3. Then people can pull the handle 134 to the front side, so that the scraping plate 133 moves to the front side. The handle 134 facilitates the movement of the scraping plate 133. The second guide bracket 131 can guide the scraping plate 133. At this time, the fifth reset spring 132 is compressed. The forward movement of the scraping plate 133 can scrape the debris remaining on the placing seat 3. After the debris is scraped, people release the handle 134, and then the scraping plate 133 moves to the rear side to reset under the action of the fifth reset spring 132. The rearward movement of the scraping plate 133 drives the handle 134 to move to the rear side to reset. The above operation can facilitate the scraping of the debris remaining on the placing seat 3.
