Description

Technical Field

[0001] This utility model relates to the field of soil breaking devices, specifically an agricultural planting soil breaking device. Background Technology

[0002] Crop farming is one of the main components of agriculture, and soil is the material basis of agricultural production. When testing the composition of soil, it is necessary to use a soil crushing device to crush the soil clumps before conducting soil composition testing.

[0003] For example, CN217615009U discloses a soil-crushing device for agricultural planting. A second lead screw drives a support rod to move, causing the position of the fixed-length support rod to change. This tilts the filter seat within the machine body to the baffle position. A first lead screw then drives a cleaning seat to move on the filter seat, allowing the cleaning seat to push residual gravel and impurities on the filter screen from the recycling channel into the recycling bin. This eliminates the need for manual removal of the filter screen, making cleaning more convenient. The torsion spring provides auxiliary support to the support rod and assists the second lead screw in limiting the movable plate, preventing the filter seat from tilting unnecessarily and affecting soil filtration.

[0004] This patent requires the soil to be sieved after it has been crushed. However, because the soil is fed into a relatively fixed position, the soil will only fall into one place on the sieve, causing blockage at that point and preventing the sieve from being used effectively, thus affecting the sieving of the soil. Utility Model Content

A connecting rod a is fixedly connected to the other end of the connecting shaft. A screening mechanism is provided at the bottom of the machine body.

[0008] Specifically, the feeding auger and the discharge chute work together to evenly feed soil onto the crushing roller for rapid crushing, and the distribution plate can evenly distribute the crushed soil.

[0009] Preferably, a synchronous pulley a is fixedly connected to the outer side of the output shaft of the motor b, and a synchronous belt is sleeved on the outer side of the synchronous pulley a.

[0010] Specifically, the synchronous pulley a and the synchronous belt are used to transmit the power output by the motor b.

[0011] Preferably, one end of the timing belt is fitted with a timing pulley b, and one side of the timing pulley b is movably connected to the machine body via a rotating shaft.

[0012] Preferably, a connecting rod b is fixedly connected to the other side of the synchronous pulley b, and a protrusion is fixedly connected to one end of the connecting rod b. The outer side of the protrusion is slidably connected to the connecting rod a.

[0013] Specifically, the synchronous pulley b is used to transmit the power of the motor b to the connecting rod b, so that the connecting rod b moves the connecting rod a back and forth through the protrusion.

[0014] Preferably, the screening mechanism includes a rack rod fixedly connected to one end of the connecting rod a. The rack rod has an arc shape, and a connecting gear is meshed at the bottom of the rack rod. A transmission rod is fixedly connected to one side of the connecting gear.

[0015] Specifically, the rack and pinion is used to mesh with the gear, driving it and the transmission rod on one side to rotate.

[0016] Preferably, the outer side of the transmission rod is movably connected to the machine body via a bearing, and both ends of the transmission rod are fixedly connected to eccentric wheels, with the outer side of the eccentric wheels abutting against a screening plate.

[0017] Specifically, the eccentric wheel is used to lift the screening plate when it rotates, so that the screening plate moves up and down.

[0018] Preferably, the screening plate is slidably connected to slide rods on all four sides, the two ends of the slide rods are fixedly connected to the machine body, and springs are abutted on both sides of the screening plate, with the inner side of the springs sleeved with the slide rods.

[0019] Specifically, the spring is used to reset the screen plate that moves up and down, and the slide bar is used to limit the movement of the screen plate.

[0022] Compared with existing technologies, the beneficial effects of this agricultural planting soil-breaking device are:

[0023] 1. In this agricultural soil-crushing device, when the motor b drives the feeding auger to rotate and feed material, it also drives the synchronous wheel a in the material distribution mechanism to rotate. The synchronous wheel a drives the synchronous wheel b to rotate through the synchronous belt. The synchronous wheel b then drives the connecting rod b to rotate, causing the protrusion at one end of the connecting rod b to slide in the strip groove inside the connecting rod a, causing the connecting rod a to swing back and forth. The connecting rod a can drive the connecting shaft and the material distribution plate to swing back and forth as well. When the material distribution plate swings, it can evenly distribute the soil crushed by the soil-crushing roller, so that it falls evenly onto the screening plate for screening, making full use of the screening plate. In this way, the crushed soil in the soil-crushing device can be evenly fed and screened.

[0024] 2. In this agricultural soil crushing device, to increase the screening speed during soil crushing, a set of rack rods is installed at the end of the connecting rod a. The rack rods swing with the connecting rod a and mesh with the connecting gear, thereby driving the connecting gear to rotate. When the connecting gear rotates, it can also drive the transmission rod on one side to rotate, causing the eccentric wheel on the outside of the transmission rod to rotate. When the eccentric wheel rotates, it can lift and lower the screening plate, allowing the screening plate to slide on the outside of multiple sets of sliding rods and compress the springs at the top and bottom. In this way, the screening plate will shake up and down, allowing the soil on the screening plate to be screened quickly. The rubber sleeve can prevent the crushed soil from entering the through holes around the screening plate. Through the above operation, it is convenient to quickly screen the crushed soil in the soil crushing device. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-3 This utility model provides a technical solution: an agricultural planting soil-crushing device, comprising: a body 1 and a material distribution mechanism 6. A motor a2 is mounted on one side of the body 1 via a bracket. A drive gear 3 is fixedly connected to the output end of the motor a2. A driven gear 4 is meshed with the outer side of the drive gear 3. Soil-crushing rollers 5 are fixedly connected to both the driven gear 4 and one side of the drive gear 3.

[0032] A motor b8 is mounted on the top of one side of the machine body 1 via a bracket. The output end of the motor b8 is fixedly connected to a feeding auger 9. A feeding chute 10 is provided at the bottom of the feeding auger 9. The feeding chute 10 is located inside the machine body 1. A feed inlet 11 is provided at the top of the machine body 1. A material distribution mechanism 6 is provided inside the machine body 1. The material distribution mechanism 6 includes a connecting shaft 601 that is movably connected to the machine body 1 via a bearing. A material distribution plate 602 is fixedly connected to one end of the connecting shaft 601. One end of the material distribution plate 602 is movably connected to the machine body 1 via a rotating shaft. A connecting rod a603 is fixedly connected to the other end of the connecting shaft 601. A screening mechanism 7 is provided at the bottom of the machine body 1.

[0033] A synchronous pulley a604 is fixedly connected to the outer side of the output shaft of motor b8, and a synchronous belt 605 is sleeved on the outer side of synchronous pulley a604; a synchronous pulley b606 is sleeved on one end of synchronous belt 605, and one side of synchronous pulley b606 is movably connected to the machine body 1 through a rotating shaft; a connecting rod b607 is fixedly connected to the other side of synchronous pulley b606, and a protrusion 608 is fixedly connected to one end of connecting rod b607, and the outer side of protrusion 608 is slidably connected to connecting rod a603.

[0034] In practical implementation, this agricultural soil-crushing device feeds soil into the machine body 1 through the feed inlet 11. Then, motor b8 is started to drive the feeding auger 9 to rotate, which feeds the soil evenly through the discharge chute 10 between the two sets of soil-crushing rollers 5. Next, motor a2 is started to drive the drive gear 3 and driven gear 4 to rotate, causing the two sets of soil-crushing rollers 5 to rotate relative to each other, thus crushing the soil. While motor b8 is driving the feeding auger 9 to feed the soil, it also drives the synchronous pulley a604 in the distribution mechanism 6 to rotate. The synchronous pulley a604, through the synchronous belt 605, drives the synchronous pulley a604 to rotate. When the step wheel b606 rotates, the synchronous wheel b606 drives the connecting rod b607 to rotate, causing the protrusion 608 at one end of the connecting rod b607 to slide in the strip groove inside the connecting rod a603, causing the connecting rod a603 to swing back and forth. The connecting rod a603 can also drive the connecting shaft 601 and the material distribution plate 602 to swing back and forth. When the material distribution plate 602 swings, it can evenly distribute the soil crushed by the soil crushing roller 5, so that it falls evenly onto the screening plate 705 for screening, making full use of the screening plate 705. In this way, the crushed soil in the soil crushing device can be evenly fed and screened.

[0035] Please see Figure 1 , Figure 2 and Figure 4The screening mechanism 7 includes a rack 701 fixedly connected to one end of the connecting rod a603. The rack 701 is arc-shaped, and a connecting gear 702 is meshed with the bottom of the rack 701. A transmission rod 703 is fixedly connected to one side of the connecting gear 702. The outer side of the transmission rod 703 is movably connected to the machine body 1 through a bearing. Eccentric wheels 704 are fixedly connected to both ends of the transmission rod 703. The outer side of the eccentric wheels 704 abuts against a screening plate 705. Sliding rods 706 are slidably connected to all four sides of the screening plate 705. Both ends of the rod 706 are fixedly connected to the machine body 1. Springs 707 are abutted against both sides of the screening plate 705. The inner side of the spring 707 is sleeved with the slide rod 706. A rubber sleeve 708 is sleeved on the outer side of the spring 707. One end of the rubber sleeve 708 is fixed to the screening plate 705, and the other end of the rubber sleeve 708 is fixed to the machine body 1. Through holes matching the slide rod 706 are opened around the screening plate 705. The slide rod 706 and the screening plate 705 form a sliding structure. The rack rod 701 and the connecting gear 702 form a meshing transmission structure.

[0036] In practical implementation, this agricultural soil crushing device, in order to increase the screening speed when crushing soil, uses a set of rack rods 701 at the end of the connecting rod a603. The rack rods 701 swing with the connecting rod a603 and mesh with the connecting gear 702, thereby driving the connecting gear 702 to rotate. When the connecting gear 702 rotates, it can also drive the transmission rod 703 on one side to rotate, causing the eccentric wheel 704 on the outside of the transmission rod 703 to rotate. When the eccentric wheel 704 rotates, it can lift and lower the screening plate 705, allowing the screening plate 705 to slide on the outside of multiple sets of sliding rods 706 and squeeze the springs 707 at the top and bottom. In this way, the screening plate 705 will shake up and down, allowing the soil on the screening plate 705 to be screened quickly. The rubber sleeve 708 can prevent the crushed soil from entering the through holes around the screening plate 705. Through the above operation, it is convenient to quickly screen the crushed soil in the soil crushing device.

[0037] In summary: When using the agricultural planting soil crushing device, soil is first fed into the machine body 1 through the feed inlet 11. Then, the motor b8 is started to drive the feeding auger 9 to rotate. The feeding auger 9 feeds the soil so that it enters evenly between the two sets of soil crushing rollers 5 through the discharge chute 10. Then, the motor a2 is started to drive the drive gear 3 and the driven gear 4 to rotate, causing the two sets of soil crushing rollers 5 to rotate relative to each other and crush the soil. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
