Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a seed bed soil pressing roller. Background Art

[0002] In order to increase soil firmness and improve the germination rate of seeds after sowing, a pressing roller is used to compact the seedbed soil after sowing while completing the sowing operation. Conventional pressing rollers mainly rely on their own weight to exert downward pressure on the seedbed soil to complete the compaction operation. When faced with special agronomic requirements and complex soil environments, the operation quality is low. In order to solve problems such as insufficient compaction and soil adhesion, vibrating pressing rollers have been developed, but this type of equipment mostly relies on external power sources to provide vibration, resulting in a cumbersome structure and high cost. It is also not suitable for conventional soil environments and still cannot meet the requirements of modern agricultural machinery in terms of practicality, adaptability and versatility. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the current actual needs for seed bed soil compaction operations, to develop and design a sowing compaction roller that can achieve rolling vibration and rolling compaction, so as to achieve the purpose of improving the adaptability of the compaction roller, simplifying the structure, reducing manufacturing costs, facilitating use, adjusting different compaction modes according to field operation needs, and providing a good seed bed environment for seed germination.

[0004] The purpose of the invention is achieved as follows: outer roller side plates are rotatably installed between the roller frames on both sides of the roller shaft, pin holes are provided on the sides of the outer roller side plates, and the pin shafts are inserted and installed in the pin holes so as to be axially movable left and right. The pin shafts are fixedly connected to the outer roller side plates by pins, and the outer rollers are fitted and fixed between the outer roller side plates on both sides. On both sides of the roller shaft, two inner roller side plates are rotatably installed between the two outer roller side plates, through holes are provided on the sides of the inner roller side plates at positions opposite to the pin holes, and the inner rollers are fitted and fixed between the two inner roller side plates, and the inner wall surfaces of the inner rollers are successively separated by an angle α of 15° along the circumferential direction. Four roller rings are staggered and fixedly installed, and six boss-type lifting sections are evenly spaced and arranged on the inner wall surface of the roller ring in the circumferential direction; four impact hammer frames are sleeved and fixedly installed on the roller shaft at a position relative to the four roller rings and perpendicular to the ground, a sliding support hole is provided at the lower end of the impact hammer frame, and the impact hammer handle can be inserted and installed in the sliding support hole so as to be axially movable up and down, and an impact hammer head is fixedly installed on the lower end of the impact hammer handle, and a pressure spring is sleeved on the impact hammer handle, and the upper and lower ends of the pressure spring are respectively in extrusion contact with the impact hammer frame and the impact hammer head, and the impact hammer head is in contact or out of contact with the six boss-type lifting sections on the inner wall surface of the corresponding roller ring in turn.

[0005] The invention realizes two compaction operation modes, namely rolling vibration and rolling compaction; the impact hammer is used to continuously strike the roller ring, thereby realizing high-frequency and high-density up and down vibration in the circular rotation of the roller and the roller ring; the pin shaft and the through hole are used to cooperate to realize the switching of the two compaction modes, namely rolling vibration and rolling compaction, which produces a good compaction effect on the seed bed soil after sowing operations in different environments; the invention has the characteristics of novel, unique, reasonable, simple, strong versatility, good compaction operation effect, and convenient and reliable use.

DETAILED DESCRIPTION

[0013] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A seeding pressing roller capable of achieving rolling vibration and rolling compaction comprises a roller frame 2, a seat plate 1 and a roller shaft 3 are respectively mounted on the front and rear ends of the roller frame 2, and is characterized in that: outer roller side plates 4 are rotatably mounted on both sides of the roller shaft 3 between the roller frame 2, a pin hole 5 is provided on the side of the outer roller side plate 4, a pin shaft 6 is inserted and mounted in the pin hole 5 so as to be axially movable left and right, the pin shaft 6 is fixedly connected to the outer roller side plate 4 by a pin 7, an outer roller 8 is fitted and fixedly mounted between the outer roller side plates 4 on both sides, two inner roller side plates 9 are rotatably mounted between the two outer roller side plates 4 on both sides of the roller shaft 3, a through hole 10 is provided on the side of the inner roller side plate 9 at a position opposite to the pin hole 5, an inner roller 11 is fitted and fixedly mounted between the two inner roller side plates 9, and the inner wall surface of the inner roller 11 is circumferentially rotatable. Four roller rings 17 are fixedly installed in an offset manner with a difference of angle α of 15° in sequence, and six boss-type lifting sections 18 are evenly spaced and arranged on the inner wall surface of the roller ring 17 in the circumferential direction; four impact hammer frames 12 are fixedly installed on the roller shaft 3 at a position relative to the four roller rings 17 perpendicular to the ground, a sliding support hole 13 is provided at the lower end of the impact hammer frame 12, and an impact hammer handle 15 is inserted and installed in the sliding support hole 13 so as to be axially movable up and down, and an impact hammer head 16 is fixedly installed on the lower end of the impact hammer handle 15, and a pressure spring 14 is mounted on the impact hammer handle 15, and the upper and lower ends of the pressure spring 14 are respectively in extrusion contact with the impact hammer frame 12 and the impact hammer head 16, and the impact hammer head 16 is in contact or out of contact with the six boss-type lifting sections 18 on the inner wall surface of the corresponding roller ring 17 in sequence.

[0014] When in use, the roller is installed on the working machine using the seat plate 1 and moved forward randomly to compact the outer roller 8 tightly against the soil of the seed bed. Under the action of soil friction resistance, the outer roller 8 starts to rotate. The suppression mode is selected according to agronomic requirements and field soil conditions.

[0015] When the rolling compaction mode is selected, the pin shaft 6 installed in the pin hole 5 and axially movable left and right is inserted into the through hole 10 opened on the inner roller side plate 9, and the inner roller 11 synchronously drives the roller ring 17 fixedly installed on the inner wall surface to rotate. When the boss-type lifting section 18 fixed on the roller ring 17 contacts the impact hammer head 16 on the impact hammer handle 15, the impact hammer handle 15 moves upward in the sliding support hole 13 on the impact hammer frame 12, and the compression pressure of the pressure spring 14 increases. When the boss-type lifting section 18 on the rotating roller ring 17 is out of contact with the impact hammer head 16, under the action of the pressure spring 14, the impact hammer handle 15 moves downward rapidly, and the impact hammer head 16 hits the inner wall surface of the roller ring 17, so that The pressing roller vibrates and applies impact force to the soil surface above the seeds through the effective contact surface. Six boss-type lifting sections 13 are fixedly installed on the inner wall surface of each roller ring 12. There are 24 boss-type lifting sections 13 on the four roller rings 12. At the same time, the four roller rings 12 are fixedly installed in the roller 6 with an offset of 15° along the circumferential direction. That is, every time the roller 6 rotates 15°, one boss-type lifting section 13 is disengaged from the impact hammer 11, and the impact hammer 11 impacts the inner wall surface of the roller ring 12 once. The roller 6 rotates 360°, and the four impact hammers impact the inner wall surface of the roller ring 12 24 times. The roller 6 vibrates 24 times, completing the high-frequency vibration suppression of the seed bed soil and realizing rolling compaction operation.

[0016] When the rolling compaction mode is selected, the pin shaft 6 installed in the pin hole 5 so as to be movably installed axially left and right is disengaged from the insertion fit with the through hole 10 provided on the side plate 9 of the inner roller, and the inner roller is driven to rotate without power. At this time, there is no exciting force to stimulate the pressing roller. Only the weight of the pressing roller itself acts on the soil through the outer roller 8, exerting downward pressure on the soil to compact it, thereby realizing rolling compaction operation.
