Description

Technical Field

[0001] The utility model belongs to the technical field of seed detection, in particular to a seed detection sample crusher. Background Art

[0002] Some seeds need to be crushed and tested before planting. The traditional inspection method is to manually crush and screen out the seed shells, and then observe and test. There are also seed crushing machines, such as the crusher disclosed in the utility model patent with application number CN202321046435.0, which includes a crushing mechanism, a screening mechanism, a cleaning mechanism, etc. After the seeds are crushed by the crushing mechanism, they fall into the screening mechanism for screening and fall into the receiving box for subsequent testing. When the screening mechanism is screening, the top block pushes the screening net to move in the horizontal direction, and the spring drives the screening net to reset to complete the screening. When some harder seed shells are stuck in the sieve holes of the screening net, only the screening net is controlled to move back and forth in the horizontal direction, which makes it difficult to get the seed shells out of the sieve holes, which will reduce the screening efficiency and even cause incomplete screening, and further improvement is needed. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] The present application embodiment provides a seed detection sample crusher, such as Figure 1-Figure 4 As shown, it includes a rectangular housing 1, a cam 4, a first receiving tray 6, etc.

[0023] Specifically, one side of the rectangular shell 1 has an opening 101, in which a pair of rolling rollers 2 with opposite rotation directions are arranged for crushing seeds, and a sieve plate 3 is arranged below the rolling roller 2, one side of the sieve plate 3 is rotatably connected to the inner wall of the rectangular shell 1 through a first connecting rod 301, and the axial setting of the first connecting rod 301 is the same as the axial setting of the rolling roller 2; the cams 4 are a pair, both of which are sleeved outside a second connecting rod 401, one end of the second connecting rod 401 is rotatably connected to one end of the rectangular shell 1, and the other end of the second connecting rod 401 passes through the other end of the rectangular shell 1 and is connected to the output shaft of a motor 5, and the setting of the motor 5 is the same as that of the rolling roller 2. On the rectangular shell 1, specifically, the vertical spacing between the second connecting rod 401 and the first connecting rod 301 can be set to 8 cm, the radius of the second connecting rod 401 is 2 cm, the distance between the axis of the second connecting rod 401 and the non-protruding part of the cam is set to 8 cm, and the distance between the axis of the second connecting rod 401 and the protruding part of the cam is set to 10 cm. This can achieve that when the protruding end of the cam 4 rotates toward the sieve plate 3, the sieve plate 3 tilts upward, and when the protruding end of the cam 4 rotates toward the other side of the rectangular shell 1, the sieve plate 3 tilts downward; the first receiving plate 6 is spaced below the cam 4 to receive the seeds sieved by the sieve plate 3.

[0024] During actual use, a pair of rolling rollers 2 are controlled to rotate, and then the seeds to be crushed are placed in the gap between the pair of rolling rollers 2. After the seeds are crushed, they fall onto the sieve plate 3, and then the motor 5 is controlled to drive the second connecting rod 401 and the cam 4 to rotate. As the cam 4 rotates, the protruding part of the cam 4 rotates toward and abuts against the sieve plate 3, which lifts the sieve plate 3 and tilts it upward. The seeds will also roll due to gravity and fall into the sieve holes for screening. When the protruding part of the cam 4 rotates to face the other side of the rectangular shell 1, the sieve plate 3 rotates downward to the lowest point. In this way, the sieve plate 3 can be shaken up and down. While screening the seeds, the seed shells stuck in the sieve holes can also be shaken out to prevent the sieve holes from being blocked, thereby improving the screening efficiency.

[0025] Preferably, see Figure 2 , Figure 3, both ends of the rectangular shell 1 are provided with a strip-shaped through groove 102 along the width direction of the rectangular shell 1, the second connecting rod 401 is slidably connected in the strip-shaped through groove 102, the other side of the rectangular shell 1 is connected with a telescopic mechanism 7, the movable end of the telescopic mechanism 7 is rotatably connected with the second connecting rod 401, a pair of transverse slide grooves 103 are provided on the outer side of the other end of the rectangular shell 1, and the motor 5 is slidably connected with the pair of transverse slide grooves 103 through a pair of connecting plates 501. After the telescopic mechanism 7 drives the second connecting rod 401 and the cam 4 to move to the other side of the rectangular shell 1, the sieve plate 3 will rotate downward due to its own gravity, and the seed shells can be poured out. At this time, the cam 4 is controlled to rotate, and the sieve plate 3 can also be driven to shake, so that the seed shells stuck in the sieve holes are separated from the sieve plate 3.

[0026] Preferably, see Figure 1 A second receiving tray 8 is provided below the first receiving tray 6, two pairs of support bars 801 are provided in the rectangular housing 1, and the first receiving tray 6 and the second receiving tray 8 are respectively provided above the two pairs of support bars 801. After the first receiving tray 6 receives the seeds screened by the sieve tray 3, the first receiving tray 6 is taken out, and the telescopic mechanism 7 is controlled to drive the second connecting rod 401 and the cam 4 to move to the other side of the rectangular housing 1, and the sieve tray 3 is rotated downward to pour the seed shells into the second receiving tray 8.

[0027] Preferably, see Figure 1 , Figure 4 Baffles 9 are provided on both sides of the sieve plate 3, and one baffle 9 facing the opening 101 is tilted outward. The baffle 9 can prevent the seeds in the sieve plate 3 from flying out of the sieve plate 3 when the sieve plate 3 shakes up and down. The baffle 9 facing the opening 101 is tilted outward, so that when the telescopic mechanism 7 is retracted, the sieve plate 3 rotates downward, and the seed shells in the sieve plate 3 can fall out of the sieve plate 3 along the tilted baffle 9.

[0028] For details, see Figure 1 A feed hopper 10 is provided above the rolling roller 2, and the discharge port of the feed hopper is arranged toward the gap between the pair of rolling rollers 2. When crushing seeds, the seeds can be put in from the feed hopper 10, which can avoid contact between the workers and the rolling roller 2 when putting in the seeds, reducing safety hazards.

[0029] The above are only some of the embodiments listed in this application and are not intended to limit this application.
