Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-7 , the present utility model details the above technical solutions through the following embodiments:

[0026] A sunflower seed squeezing and opening machine, comprising two side seats 1, a guiding plate 2, a support frame 3 and a collection box 4. On the two side seats 1, a first squeezing roller 5 and a second squeezing roller 6 are rotatably arranged. The height of the first squeezing roller 5 is lower than that of the second squeezing roller 6. An extrusion gap 7 is formed between the first squeezing roller 5 and the second squeezing roller 6. A plurality of annular grooves 51 are arranged at equal intervals on both the first squeezing roller 5 and the second squeezing roller 6. An annular boss 52 is formed between the two annular grooves 51. The width of the annular boss 52 is the same as that of the annular groove 51. An elastic washer 53 is arranged in the annular groove 51. A driving system for driving the first squeezing roller 5 and the second squeezing roller 6 to always rotate in opposite directions is arranged on one of the side seats 1. A plurality of partition plates 21 are arranged at equal intervals on the upper surface of the guiding plate 2. A guiding slideway 22 is formed between two adjacent partition plates 21. One of the two adjacent partition plates 21 is located on the central plane in the width direction of the annular boss 52, and the other partition plate 21 is located on the central plane in the width direction of the elastic washer 53. Connecting feet 23 are arranged on both sides of the guiding plate 2. The two connecting feet 23 are respectively connected to the inner walls of the two side seats 1. The guiding plate 2 is inclined, and the head end of the guiding plate 2 is located directly above the extrusion gap 7. A feeding mechanism 8 for feeding large plate sunflower seeds onto the guiding plate 2 is arranged on the support frame 3. The collection box 4 is located directly below the first squeezing roller 5 and the second squeezing roller 6.

[0027] The driving system of the present utility model is a prior art, which can be a motor and a gear, or a motor and a pulley, as long as it can drive the first squeezing roller 5 and the second squeezing roller 6 to always rotate in opposite directions, and the principle will not be elaborated here. Through the feeding mechanism 8, large plate sunflower seeds can be fed onto the guiding plate 2, and then the large plate sunflower seeds are guided into the extrusion gap 7 through all the guiding slideways 22. Since one of the two partition plates 21 forming the guiding slideway 22 is located on the central plane in the width direction of the annular boss 52, and the other partition plate 21 is located on the central plane in the width direction of the elastic washer 53, when the large plate sunflower seeds enter the extrusion gap 7, a part of the large plate sunflower seeds is squeezed by the annular bosses 52 on the first squeezing roller 5 and the second squeezing roller 6, and the other part of the large plate sunflower seeds is squeezed by the elastic washers 53 on the first squeezing roller 5 and the second squeezing roller 6. Since the elastic washer 53 itself has elasticity, after the elastic washer 53 is squeezed onto the large plate sunflower seeds, the elastic washer 53 itself will deform, and this part of the large plate sunflower seeds will not crack, while the part of the large plate sunflower seeds squeezed by the two annular bosses 52 will crack, that is, the automatic opening of the large plate sunflower seeds is realized, and the extrusion and opening efficiency of the large plate sunflower seeds is improved.

[0028] Installation feet 11 are provided at the tops of both side seats 1. A connecting rod 12 is installed between the two installation feet 11. A baffle 13 is installed on the outer wall of the connecting rod 12. The baffle 13 is located beside the head end of the guiding plate 2. The baffle 13 can block the large-sized melon seeds. After the large-sized melon seeds collide with the baffle 13, they can slide along the baffle 13 towards the extrusion gap 7. The baffle 13 can limit the moving range of the large-sized melon seeds, enabling the large-sized melon seeds to quickly enter the extrusion gap 7.

[0029] This can easily cause the large-sized melon seeds to fail to accurately enter the extrusion gap 7. The baffle 13 can block the large-sized melon seeds, and the baffle 13 can guide the moving direction of the large-sized melon seeds to ensure that the large-sized melon seeds can enter the extrusion gap 7.

[0030] A number of protrusions 54 are provided on the outer surfaces of the annular boss 52 and the elastic washer 53. The protrusions 54 can increase the grasping force on the large-sized melon seeds.

[0031] The feeding mechanism 8 includes a feeding hopper 81 and a discharge guiding frame 82. An adjusting assembly 83 for changing the size of the discharge port is provided at the discharge port of the feeding hopper 81. Mounting plates 811 are provided on both side walls of the feeding hopper 81. Four support feet 821 distributed in a rectangle are provided at the bottom of the discharge guiding frame 82. A discharge opening 822 and a guiding plate 823 are provided at the head end of the discharge guiding frame 82. The four support feet 821 and the two mounting plates 811 are all fixedly connected to the top of the support frame 3. The discharge guiding frame 82 is inclined. The guiding plate 823 is located directly above the tail end of the guiding plate 2. The discharge port of the feeding hopper 81 is located directly above the tail end of the discharge guiding frame 82.

[0032] The feeding hopper 81 can release the large-sized melon seeds from its discharge port. The released large-sized melon seeds fall onto the discharge guiding frame 82, then slide onto the guiding plate 823, and finally the large-sized melon seeds can enter the guiding slideway 22.

[0033] A vibration motor 824 is provided at the bottom of the discharge guiding frame 82. The vibration motor 824 can improve the stability of the large-sized melon seeds sliding in the discharge guiding frame 82 and can also disperse the large-sized melon seeds sticking together.

[0034] The adjusting assembly 83 includes an adjusting rotating shaft 831, an adjusting motor 832 and a linkage rod 833. One end of the adjusting rotating shaft 831 is provided with a swing rod 834. One end of the swing rod 834 is provided with a hinge shaft 8341. A material deflecting plate 835 is arranged on the outer wall of the adjusting rotating shaft 831. A linkage disc 836 is installed on the output end of the adjusting motor 832. An eccentric shaft 8361 is installed on the linkage disc 836. A suspension 812 is arranged on the side wall at one end of the feeding hopper 81. The adjusting rotating shaft 831 is rotatably arranged in the feeding hopper 81. The material deflecting plate 835 is located in the discharge port of the feeding hopper 81. The adjusting motor 832 is arranged upside down on the suspension 812. The two ends of the linkage rod 833 are respectively hinged to the hinge shaft 8341 and the eccentric shaft 8361.

[0035] The adjusting motor 832 drives the linkage disc 836 to rotate, and the eccentric shaft 8361 also rotates accordingly. The eccentric shaft 8361 drives one end of the linkage rod 833 to move. The linkage rod 833 drives the hinge shaft 8341 to swing. The hinge shaft 8341 drives the swing rod 834 and the adjusting rotating shaft 831 to swing synchronously. The material deflecting plate 835 swings synchronously with the adjusting rotating shaft 831. The size of the discharge port is adjusted by the swing of the material deflecting plate 835, so as to realize the intermittent discharge of large plate melon seeds and avoid the accumulation of large plate melon seeds together, which affects the opening quality.

[0036] A relief groove 14 for avoiding the collection box 4 is arranged at the bottom of the side seat 1, so that the collection area of the collection box 4 is enlarged and large plate melon seeds are prevented from falling outside.

[0037] A pull handle is arranged on the side wall of the collection box 4, and the collection box 4 can be easily pulled away through the pull handle.

[0038] Working principle: Pour large plate melon seeds into the feeding hopper 81. At the same time, the drive system and the vibration motor 824 work synchronously. The large plate melon seeds in the feeding hopper 81 can be discharged from its discharge port and enter the discharge guiding frame 82. The large plate melon seeds then slide onto the guide plate 823, and then the guide plate 823 pours the large plate melon seeds into the guiding slideway 22. Through the guidance of the guiding slideway 22, the large plate melon seeds can enter the extrusion gap 7. Then, the part of the large plate melon seeds squeezed by the elastic gaskets 53 on the first extrusion roller 5 and the second extrusion roller 6 does not crack, and the part of the large plate melon seeds squeezed by the annular bosses 52 on the first extrusion roller 5 and the second extrusion roller 6 cracks. Finally, the large plate melon seeds can fall into the collection box 4.
