Description

Technical Field

[0001] The utility model relates to the technical field of seed lemma stripping pieces, in particular to a lemma stripping piece device for grass-growing seeds. Background Art

[0002] Hair grass is a plant of the genus Poaceae, and its seeds have palea on the surface. When planted in the field, the palea of ​​hair grass seeds do not need to be removed, but in the process of experiments, the surface of the seeds often need to be disinfected. If the palea are not removed, the palea will make the seeds float on the surface of the disinfectant, affecting the disinfection effect, so the palea needs to be removed.

[0003] In the prior art, palea flakes are generally removed by manual kneading. After the manual kneading process, the palea flakes will be separated from the seeds inside. However, due to the small size of the grass seeds, the kneading process is time-consuming and laborious. Moreover, after the manual kneading step, the seeds and palea flakes are still mixed together and need to be separated. In the prior art, the mixture of seeds and palea flakes is generally placed on a piece of paper, and the palea flakes and other impurities are removed very carefully. Since the specific gravity of seeds and palea flakes is not much different, it takes multiple slow separation processes to completely separate the seeds and palea flakes, which is troublesome and increases the time required for separation.

[0004] Therefore, it is necessary to invent a grass seed lemma removal device to solve the above problems. Summary of the invention

[0005] In order to solve the shortcomings of the prior art, the purpose of the utility model is to provide a device for removing the lemma of grass seeds, which solves the problems in the prior art that the rubbing process is time-consuming and labor-intensive due to the small size of the grass seeds, and that the specific gravity of the seeds and the lemma is not very different, so the above-mentioned separation process needs to be repeated many times to completely separate the seeds and the lemma, which is troublesome and increases the time required for separation.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A device for removing lemmas from grass seeds comprises a base plate and a kneading oblique bucket which is detachably mounted above the base plate and has an open top end, a kneading oblique platform which is rotatably arranged in the kneading oblique bucket and can be used to rub and separate the grass seeds in the kneading oblique bucket, a material guide component which is detachably mounted on the bottom end of the kneading oblique bucket, a sloped platform with an open top surface connected to the other end of the material guide component, a plurality of guide plates are arranged in the sloped platform, air inlet grooves for blowing air into the sloped platform are connected at positions where one side wall of the sloped platform is adapted to the guide plates, a material discharge groove for blowing out lemmas is provided at positions where the other symmetrical side wall of the sloped platform is adapted to the guide plates, and a material collecting platform for collecting grass seeds is connected at one end of the sloped platform away from the material guide component.

[0008] As a preferred solution of the utility model, the material guide assembly includes a leakage plate detachably mounted on the bottom end of the kneading inclined bucket and a hemispherical collecting platform installed at the center of the bottom end of the leakage plate, a material guide pipe is connected to the bottom side of the outer peripheral side wall of the hemispherical collecting platform, and the other end of the material guide pipe is detachably connected to the top end of the inclined platform, and a plurality of leakage holes are opened in the leakage plate.

[0009] As a preferred solution of the utility model, a stand is connected to one side of the top surface of the bottom plate, a rotating member is installed at the bottom of one end of the stand, and the bottom end of the rotating member is detachably connected to the top end of the kneading ramp.

[0010] As a preferred solution of the utility model, the outer peripheral side wall of the kneading inclined bucket is connected to multiple vertical rods, the bottom ends of the multiple vertical rods are detachably connected to the top surface of the bottom plate, the inner side of the top of the kneading inclined bucket is connected to an outer material guide ring plate, and the outer side of the top of the kneading inclined platform is connected to an inner material guide ring plate.

[0011] As a preferred solution of the utility model, an inclined tube is detachably provided on one side of the outer peripheral side wall of the ramp platform, and a plurality of ventilation tubes are provided on the side wall around the inclined tube. The other end of the ventilation tube is detachably connected to the side wall of the ramp platform, and the number and position of the ventilation tubes are consistent with the air inlet slots.

[0012] As a preferred solution of the utility model, the bottom end of the material receiving table is detachably abutted against the top surface of the bottom plate, the bottom surface of the ramp table is connected to a support plate, and the bottom end of the support plate is detachably connected to the top surface of the bottom plate.

[0013] The outer surface of the kneading ramp and the inner surface of the kneading ramp are both provided with a rubber layer.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] In the utility model, the rotating kneading inclined platform rotates in the kneading inclined bucket, so that the outer surface of the kneading inclined platform and the inner surface of the kneading inclined bucket generate contact friction to knead the grass seeds in the kneading inclined bucket, thereby realizing the separation of grass seeds and palea flakes. Compared with the traditional manual rubbing method, the palea flakes can be separated for grass seeds of smaller sizes, thereby improving the separation degree and saving time and labor. On the other hand, the mixture of seeds and palea flakes after separation enters the inclined platform through the material guide component. Since the inclined platform has a certain slope, the mixture of seeds and palea flakes rolls downward. In the process of rolling in the inclined platform, Air is blown into the ramp through the air inlet slot, so that the lighter lemmas on each layer of guide plates are blown out from the discharge slot, while the heavier seeds roll down through the multiple layers of guide plates and are finally collected by the receiving table. Since multiple guide plates are set, and each ramp is provided with air inlet slots and discharge slots on both sides of the guide plates, the mixture of seeds and lemmas is separated at each guide plate, and finally the seeds and lemmas are separated through separation at multiple guide plates, thereby avoiding the situation where repeated separation treatment is required due to the small difference in specific gravity of seeds and lemmas, thereby improving separation efficiency and shortening separation time.

A kneading oblique platform 4 which can rub and separate the grass seeds in the kneading oblique bucket 7 is rotatably arranged in the kneading oblique bucket 7. A material guide component is detachably mounted on the bottom end of the kneading oblique bucket 7. The other end of the material guide component is connected to an inclined platform 13 with an open top side. A plurality of guide plates 14 are arranged in the inclined platform 13. A guide plate 14 which can be directed to the inside of the inclined platform 13 is connected at a position where a side wall of the inclined platform 13 is adapted to fit the guide plate 14. The air inlet slot 17 for blowing air and the position of the other side wall of the ramp 13 symmetrically adapted to the guide plate 14 are both provided with a discharge slot 18 for blowing out the lemma flakes. The end of the ramp 13 away from the material guide assembly is connected to a receiving platform 19 for collecting grass seeds. The outer peripheral side wall surface of the kneading ramp 4 is provided with multiple protrusions, so that the kneading ramp 4 and the kneading inclined bucket 7 are in intermittent contact, so that the grass seeds entering therein are removed from the lemma flakes through the intermittent contact friction between the rotating kneading ramp 4 and the kneading inclined bucket 7. The outer surface of the kneading ramp 4 and the inner surface of the kneading inclined bucket 7 are both provided with a rubber layer, which can reduce the risk of damage to the grass seeds.

[0024] The material guiding assembly comprises a material leakage plate 8 detachably mounted on the bottom end of the kneading inclined bucket 7 and a hemispherical collecting platform 10 mounted at the bottom center of the material leakage plate 8. A material guiding pipe 11 is connected to the bottom side of the outer peripheral side wall of the hemispherical collecting platform 10. The other end of the material guiding pipe 11 is detachably connected to the top of the inclined platform 13. A plurality of material leakage holes 20 are provided in the material leakage plate 8. The grass seeds enter the kneading inclined bucket 7 from above, and after being intermittently kneaded by the kneading inclined platform 4, they gradually fall onto the material leakage plate 8, and then enter the hemispherical collecting platform 10 through the material leakage holes 20, and then enter the inclined platform 13 through the material guiding pipe 11, thereby completing the separation process of the seeds and the palea.

[0025] A vertical frame 2 is connected to one side of the top surface of the bottom plate 1, and a rotating member 3 is installed at the bottom of one end of the vertical frame 2. The bottom end of the rotating member 3 is detachably connected to the top of the kneading ramp 4. The rotating member 3 can be a motor, so that the kneading ramp 4 is driven to rotate by the rotation of the motor, so that the intermittent contact friction between the rotating kneading ramp 4 and the kneading bucket 7 is used to remove the lemma of the grass seeds entering therein.

[0026] The outer peripheral side wall of the kneading inclined bucket 7 is connected to multiple vertical poles 6, and the bottom ends of the multiple vertical poles 6 are detachably connected to the top surface of the bottom plate 1. The inner side of the top of the kneading inclined bucket 7 is connected to an outer material guide ring plate 9, and the outer side of the top of the kneading inclined platform 4 is connected to an inner material guide ring plate 5. The outer material guide ring plate 9 and the inner material guide ring plate 5 can expand the distance between the kneading inclined platform 4 and the kneading inclined bucket 7, thereby serving as a channel for grass seeds to enter.

[0027] An inclined tube 15 is detachably provided on one side of the outer peripheral side wall of the inclined platform 13, and a plurality of ventilation tubes 16 are provided on the side wall around the inclined tube 15. The other end of the ventilation tube 16 is detachably connected to the side wall of the inclined platform 13, and the number and position of the ventilation tubes 16 are consistent with the air inlet groove 17. The inclined tube 15 can be connected to an external fan, so that the air volume generated by the fan is filled into the inclined platform 13 through the ventilation tube 16 and the air inlet groove 17, and then the seeds and the lemma are separated by blowing.

[0028] The bottom end of the material receiving platform 19 is detachably connected to the top surface of the bottom plate 1 , and the bottom surface of the ramp platform 13 is connected to the support plate 12 , and the bottom end of the support plate 12 is detachably connected to the top surface of the bottom plate 1 , and the support plate 12 can fix the position of the ramp platform 13 on the bottom plate 1 .

[0029] In the utility model, the rotating kneading inclined platform 4 rotates in the kneading inclined bucket 7, so that the grass seeds in the kneading inclined bucket 7 are kneaded through the contact friction between the outer surface of the kneading inclined platform 4 and the inner surface of the kneading inclined bucket 7, so as to achieve the separation of seeds and palea flakes. Compared with the traditional manual rubbing method, the palea flakes can be separated for grass seeds of smaller sizes, thereby improving the degree of separation and saving time and labor. On the other hand, after separation, the mixture of seeds and palea flakes enters the inclined platform 13 through the material guide component. Since the inclined platform 13 has a certain slope, the mixture of seeds and palea flakes rolls downward. In the process of rolling in the inclined platform 13, the mixture of seeds and palea flakes is passed through the air inlet slot 17. Blow air into the ramp platform 13, so that the light lemmas on each layer of guide plate 14 are blown out from the discharge trough 18, while the heavy seeds roll down through the multi-layer guide plates 14, and are finally collected by the receiving platform 19. Since multiple guide plates 14 are set, and each ramp platform 13 is provided with air inlet grooves 17 and discharge troughs 18 on both sides of the guide plates 14, the mixture of seeds and lemmas is separated at each guide plate 14, and finally the separation of seeds and lemmas is completed through the separation at multiple guide plates 14, avoiding the situation that the separation process needs to be repeated many times due to the small difference in specific gravity between seeds and lemmas, improving the separation efficiency and shortening the separation time. In addition, when there is a small amount of lemmas in the seeds after one blowing separation, the seeds can be added back to the outer guide ring plate position for secondary blowing separation (the kneading part does not need to work again) to ensure that the lemmas are separated cleanly from the seeds.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
