Description

Technical Field

[0001] The invention belongs to the technical field of collecting devices, and in particular relates to a collection device for forage grass seeds. Background Art

[0002] Forage seeds are an important source of feed in animal husbandry, providing sufficient food for herbivores such as cattle and sheep. There are many types of forage seeds, including alfalfa, oats, ryegrass, tall fescue, red bean grass, clover, lotus root, Sudan grass, king bamboo grass, Mexican corn grass, Rumex, and pine grass. These forage seeds have their own characteristics, adapt to different climates and soil conditions, and meet the nutritional needs of various livestock. Drying of forage seeds is an important processing step after seed harvesting. After harvesting, seeds usually contain high moisture, which is not conducive to seed storage and long-term preservation. Drying can reduce the moisture content of seeds, making them reach or approach the moisture standard for safe seed storage. This can not only reduce the consumption of nutrients by the physiological growth of seeds, but also kill or inhibit harmful microorganisms, accelerate the ripening of seeds, and increase the germination rate and germination speed of seeds.

[0003] At present, the drying of forage grass is generally carried out by spreading it on cement pavement or cement ground. After the drying is completed, the laid seeds need to be collected. There are methods of manual collection using tools such as brooms, dustpans, shovels, etc., and there are also methods of faster collection using collection equipment with negative pressure suction function. The method can be freely selected according to the size of the site and the amount of drying. However, no matter which method is used, during the collection process, small stones, soil blocks, dust and other impurities on the road surface or the ground will be collected together with the seeds, and subsequent screening is required, which not only wastes time, but also easily increases the possibility of mechanical damage to the seed particles. For this reason, we propose a collection device for forage grass seeds to solve this problem. Summary of the invention

[0048] A push rod 3 is installed on the back of the collection compartment 1, a control device 33 is installed on the top of the push rod 3, and a touch display screen is provided on the top of the control device 33.

[0049] The push rod 3 is used to push the device, and the control device 33 is used to control the operation of the device.

[0050] The lifting mechanism includes a guide rail 6 installed on the front side of the collection compartment 1, an electric telescopic rod 5 is installed on the top of the guide rail 6, a slider 37 is slidably installed on the inner side of the guide rail 6, the piston rod end of the electric telescopic rod 5 is connected to the slider 37, and one end of the slider 37 is connected to the suction collection cover 7 through a connecting rod.

[0051] The electric telescopic rod 5 is controlled to drive the slider 37 and the suction and collection cover 7 to descend along the guide rail 6 until the side guide wheel 9 contacts the ground, and the seeds can be sucked in. When the seeds are not collected, the suction and collection cover 7 can be lifted to avoid affecting the walking performance of the device during daily movement.

[0052] The disc brush device includes a side plate of the suction and collection cover 7, through which a wheel axle 10 is installed through a bearing. The two ends of the wheel axle 10 are respectively connected to the side guide wheel 9 and the second bevel gear 15. A rotating shaft mounting seat 11 is provided on the inner side of the suction and collection cover 7. A rotating shaft 12 is rotatably mounted on the inner side of the rotating shaft mounting seat 11. A disc brush 13 is installed at the bottom of the rotating shaft 12.

Through the two groups of disc brushes 13 rotating in opposite directions, the seeds can be sucked into the collecting cover 7 on both sides and gathered to the middle position, so that the seeds can be sucked in easily.

[0054] A rubber scraper 8 is provided on the side plate of the suction collection cover 7 .

[0055] The provision of the rubber scraper 8 can prevent the seeds from leaking out from the gap between the lower side plate of the suction collection cover 7 and the ground.

[0056] The air outlet of the negative pressure fan 17 is connected to an air outlet pipe 32 , and the air outlet pipe 32 passes through the outside of the collecting compartment 1 .

[0057] The air outlet pipe 32 is used to discharge the airflow sucked by the negative pressure fan 17 .

[0058] An anti-wear wheel 25 is installed on the top of the screening box 20 , and the anti-wear wheel 25 is in contact with the eccentric thumbwheel 24 .

[0059] The anti-wear wheel 25 can roll when in contact with the eccentric dial wheel 24 , which not only reduces wear but also improves the smoothness of the eccentric dial wheel 24 in moving the screening box 20 .

[0060] The large particle impurity screening net 21 and the small particle impurity screening net 22 are both arranged obliquely.

[0061] The large particle impurity screening net 21 and the small particle impurity screening net 22 are both inclined so that the large particle impurities intercepted by the large particle impurity screening net 21 and the seeds intercepted by the small particle impurity screening net 22 can slide into the collection container for discharge and collection.

[0062] The impurity collection and discharge device includes a down pipe 26 connected to the side of the screening box 20 and a bottom collecting bin 27 connected to the bottom of the screening box 20. The bottom of the down pipe 26 is connected to the bottom collecting bin 27. The bottom of the bottom collecting bin 27 is penetrated by a waste discharge port 34. The bottom of the collecting compartment 1 is penetrated by a through opening.

[0063] The larger stones and soil blocks retained on the large particle impurity screening net 21 can gradually slide into the drop pipe 26 and finally enter the bottom collecting bin 27, while the fine dust particles and other impurities and unfilled seeds can be screened through the mesh holes on the small particle impurity screening net 22 and fall into the bottom collecting bin 27. The impurities and unfilled seeds entering the bottom collecting bin 27 can be discharged to the outside of the device through the waste outlet 34 at the bottom.

[0064] The seed collecting bin 30 is inserted and installed inside the collecting compartment 1 , and a collecting drawer 35 is inserted and installed inside the seed collecting bin 30 .

[0065] The seed collecting bin 30 is used to collect the sieved seeds. The seeds are collected in the collecting drawer 35. When the seeds need to be taken out, the collecting drawer 35 can be pulled out.

[0066] The working principle and use process of the present invention are as follows: when the device is used, the device is pushed by the cart rod 3 to move with the walking wheels 2, and the device is controlled by the control device 33. When the grass seeds laid on the road or cement ground are collected, the electric telescopic rod 5 is controlled to drive the slider 37 and the suction collection cover 7 to be lowered along the guide rail 6 until the side guide wheel 9 contacts the ground. The guide rail 6 is used to assist in guiding and reinforcing the lifting of the suction collection cover 7. After the negative pressure fan 17 and the motor 23 are turned on, the device can be pushed to move to collect the grass seeds. The negative pressure of the negative pressure fan 17 causes the grass seeds that enter the inner side of the suction collection cover 7 as the suction collection cover 7 moves to be sucked into the suction hose 16 and passed through the suction hose 16. The seeds enter the T-shaped tube 36 through the suction hose 16, and are blocked by the filtering device 31 so that the seeds will not enter the negative pressure fan 17. The airflow sucked by the negative pressure fan 17 is discharged to the outside of the device through the air outlet pipe 32, and is discharged into the screening box 20 through the first connecting hose 18 by gravity. During the walking process, the side guide wheel 9 rotates and drives the second bevel gear 15 to rotate. The first bevel gear 14 is driven by the second bevel gear 15 to rotate together with the rotating shaft 12 and the disc brush 13. The two sets of disc brushes 13 with opposite rotation directions can help the seeds to be sucked into the collecting cover 7 on both sides and gather to the middle position, so as to facilitate the seeds to be sucked in. The setting of the rubber scraper 8 can prevent the seeds from being sucked into the gap between the bottom of the side plate of the collecting cover 7 and the ground. When the seeds enter the screening box 20, the eccentric dial wheel 24 is driven to rotate by the motor 23, and the eccentric protrusion of the eccentric dial wheel 24 contacts the anti-wear wheel 25, and the anti-wear wheel 25 is driven to descend together with the screening box 20 through the contact with the anti-wear wheel 25, and the spring telescopic rod 19 is compressed by the descent of the screening box 20. When the eccentric protrusion of the eccentric dial wheel 24 leaves the anti-wear wheel 25, the screening box 20 bounces upward under the rebound force of the spring telescopic rod 19, driving the seeds on the internal large-particle impurity screening net 21 to flip and throw, and the seed particles and some small dust particles pass through the mesh holes on the large-particle impurity screening net 21 and fall onto the top of the small-particle impurity screening net 22, while the larger stones and soil blocks remain on the large-particle impurity screening net 22. The large-particle impurity screening net 21 is placed above the seed sieve 21, and gradually slides into the drop pipe 26 through the inclined large-particle impurity screening net 21, and finally enters the bottom collecting bin 27. The seed particles falling above the small-particle impurity screening net 22 can be screened again, and the seeds with full particles can be left above the small-particle impurity screening net 22, while the fine dust particles and other impurities and the unfull seeds are screened through the meshes on the small-particle impurity screening net 22 and fall into the bottom collecting bin 27. The impurities and unfull seeds entering the bottom collecting bin 27 can be discharged to the outside of the device through the waste outlet 34 at the bottom, while the seeds remaining above the small-particle impurity screening net 22 slide into the seed output port 28 through the inclined small-particle impurity screening net 22.The seeds are then transported to the collection drawer 35 in the seed collection bin 30 through the second connecting hose 29 for collection. In summary, the device can conveniently collect the grass seeds laid on the cement pavement or ground for drying, and can also screen out the stones, bumps, fine dust and some seeds with incomplete particles mixed into the seeds during the drying process, without the need for additional screening processes, thereby improving the seed quality and cleanliness.
