[0031] [First embodiment]
[0032] like Figure 1-4 The first embodiment provided by the utility model is shown, and the embodiment provides a rice seedling matrix screening device, including a screening machine 1, a feed hopper 4 is arranged on the top of the screening machine 1, and collecting devices 3 are arranged on both sides of the bottom of the screening machine 1. When the screening machine is used to screen the seedling matrix, the seedling matrix will be put into the top feed hopper 4, and then fall into the filter net inside the screening machine 1. By starting the vibration motor to drive the screening machine 1 to vibrate, the seedling matrix will vibrate synchronously on the filter net, and the finer seedling matrix will pass through the filter net and be screened out from one side of the screening machine and fall into the collecting device 3 on one side of the bottom, while the larger particles cannot pass through the filter net and slide out from the other end of the filter net and fall into the collecting device 3 on the other side of the bottom, thereby realizing the screening and processing of the seedling matrix.
[0033] In this embodiment, an anti-blocking device 2 is provided on one side of the feed hopper 4 to knock on the discharge port of the feed hopper to cause vibration inside the feed hopper, thereby reducing the accumulation of seedling matrix at the outlet of the feed hopper during feeding, reducing the occurrence of blockage and jamming, and improving the feeding speed and screening processing efficiency.
[0034] like Figure 2-3 As shown, the anti-blocking device 2 in this embodiment includes a U-shaped frame 21 fixedly connected to the outer side of the feed hopper 4, a round rod 22 is rotatably penetrated and connected inside the U-shaped frame 21, a knocking frame 23 is fixed to the outer periphery of the round rod 22, a knocking hammer 24 is fixedly connected to the outer end of the knocking frame 23, a torsion spring 25 is symmetrically sleeved on the outer periphery of the round rod 22, the two ends of the torsion spring 25 are respectively fixedly connected to the U-shaped frame 21 and the knocking frame 23, a circular gear 26 is fixedly connected to the bottom end of the round rod 22, a circular hole frame 27 is fixedly connected to the outer side of the screening machine 1, a fan-shaped gear 28 is rotatably connected to the inner wall of the circular hole frame 27, the fan-shaped gear 28 is correspondingly meshed with the circular gear 26, a motor 29 is fixed to the bottom of the circular hole frame 27, and the output end of the motor 29 is fixedly connected to the fan-shaped gear 28. By setting the anti-blocking device 2, after the seedling matrix is placed in the feed hopper, the motor 29 can be started to drive the sector gear 28 to rotate in the inner wall of the circular hole frame 27, thereby driving the circular gear 26 meshing therewith to rotate, so that it drives the round rod 22 to rotate to a certain angle in the inner wall of the U-shaped frame 21. The rotation of the round rod 22 will drive the knocking frame 23 and the knocking hammer 24 to rotate and knock toward one side of the feed hopper 4, and cause the torsion spring 25 to deform. When the outer edge of the sector gear 28 with the meshing teeth is completely disengaged from the circular gear 26, the torsion spring 25 will drive the round rod 22 and the knocking frame 23 to reset due to its own reset effect, thereby driving the knocking hammer 24 to knock toward the other end of the feed hopper, thereby reciprocatingly knocking on the discharge port of the feed hopper 4, causing vibration inside it, reducing the accumulation of the seedling matrix at the outlet of the feed hopper during feeding, reducing the occurrence of blockage and jamming, and improving the feeding speed and the efficiency of screening processing.
[0035] As a further preference of the present embodiment, the motor 29 uses a bidirectional drive motor to meet the user's needs for knocking at different positions to prevent feed blockage, and at the same time make the knocking force on both sides of the screening machine 1 more balanced. A protective cover 210 is fixedly connected to the bottom of the circular hole frame 27, and the motor 29 is arranged inside the protective cover 210. By setting the protective cover, the motor can be protected on one side of the screening machine, so that if it hits during use, it is not easy to damage the motor. The output end periphery of the motor 29 is sleeved with a bearing 211, and the outer ring of the bearing 211 is fixedly connected to the inner wall of the circular hole frame 27. By setting the bearing, the rotational wear between the fan gear and the inner wall of the circular hole frame can be reduced, and the service life of both can be improved. The two sides of the percussion hammer 24 contacting the outer wall of the feed hopper 4 are symmetrically provided with protective blocks 212, and the protective blocks 212 are made of rubber material. By setting the protective blocks, the surface of the percussion hammer can be protected, so that when the feed hopper is knocked, the outer surface of the percussion hammer is not easy to be damaged, and the service life is improved.
[0036] like Figure 4 As shown, the collecting device 3 in this embodiment includes a collecting box 33, and a card slot 31 is symmetrically opened at the bottom of the screening machine 1. A card rod 34 is fixedly connected to one side of the collecting box 33, and the card rod 34 is inserted into the inside of the card slot 31; the two ends of the bottom of the screening machine 1 are symmetrically rotatably connected with the limiting rod 32, and the top of the card rod 34 is symmetrically fixed with a magnet block 35, and the limiting rod 32 and the magnet block 35 are limitedly matched. The limiting rod 32 is made of iron material, and the magnet block 35 and the limiting rod 32 are magnetically attracted to each other. By setting the collecting device, and by the plug-in match of the card rod and the card slot, and the magnetic attraction match of the limiting rod and the magnet block, the collecting device can be fixedly loaded and unloaded at the bottom of the screening machine, and the loading and unloading is simple and time-saving. At the same time, the installation is stable and the risk of loosening is reduced.
[0037] As a further preference of this embodiment, the cross-section of the card rod 34 is trapezoidal, and one end of the card rod 34 in the trapezoidal shape is arranged away from the collection box 33. By setting one end of the card rod to be trapezoidal, the area of one end of the card rod can be reduced, making it convenient to quickly insert it into the inner wall of the slot; in addition, both sides of the collection box 33 are fixedly connected with handle blocks 36, and the cross-section of the handle blocks 36 is semicircular. By setting the handle blocks, the contact area on both sides of the collection box can be increased, making it convenient to manually hold it and carry it.
[0038] The specific working process of this embodiment is as follows:
[0039] When the screening machine 1 is used to screen the seedling matrix, the seedling matrix is placed in the feed hopper 4 and then falls onto the filter screen on the screening machine 1. By starting the screening machine 1 to vibrate, the seedling matrix will vibrate synchronously on the filter screen. The finer seedling matrix will pass through the filter screen and be screened out from one side of the screening machine 1, while larger particles will slide out from the other end of the filter screen, thereby realizing the screening and processing of the seedling matrix.
[0040] After the seedling matrix is placed in the feed hopper 4, the starting motor 29 drives the sector gear 28 to rotate in the inner wall of the circular hole frame 27, thereby driving the circular gear 26 to rotate, so that it drives the round rod 22 to rotate to a certain angle in the inner wall of the U-shaped frame 21. The rotation of the round rod 22 will drive the knocking frame 23 and the knocking hammer 24 to rotate and knock toward one side of the feed hopper 4, and deform its torsion spring 25. When the outer surface of the sector gear 28 is completely detached from the circular gear 26, the torsion spring 25 will drive the round rod 22 and the knocking frame 23 to reset, thereby driving the knocking hammer 24 to knock toward the other end of the feed hopper 4, thereby reciprocatingly knocking on the discharge port of the feed hopper 4, causing vibration inside it, reducing the accumulation of the seedling matrix at the outlet of the feed hopper during feeding, reducing the occurrence of blockage and jamming, and improving the feeding speed and the efficiency of screening processing.
[0041] Before using the screening machine 1 to screen and filter the seedling matrix, first hold the handle block 36 to insert the clamping rod 34 on one side of the collecting box 33 into the inner wall of the clamping groove 31, and then rotate the limiting rod 32 to rotate it to a certain angle on one side of the screening machine 1, so that one side of it abuts against one side of the clamping rod 34 and is adsorbed and fixed by the magnet block 35, so that the collecting box 33 can be limited on one side of the screening machine 1, and the screened seedling matrix can be collected to facilitate its later processing. At the same time, limiting the collecting box 33 can avoid shaking when receiving the material, and realize the fixed loading and unloading of the collecting device at the bottom of the screening machine. The loading and unloading is simple and time-saving. At the same time, the installation is stable and the risk of loosening is reduced.
[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
