Referring to fig. 15 and 16, in order to analyze the principle of the throwing angle, scattering angle and throwing distance of the fertilizer, the throwing surface formed by the fertilizer on the ground is analyzed, and as the side throwing device realizes the side throwing by obliquely throwing upwards, a fan-shaped throwing surface can be seen from top to bottom, the top view angle is shown in fig. 15, and the side view angle is shown in fig. 16, wherein v is0The speed of the fertilizer when leaving the scattering device; deltazIs the maximum throw-off included angle region; deltamaxIs the maximum throw-off included angle; deltaminIs the minimum throw-away included angle; beta is a scattering angle; and L is the casting distance. Above each parameter is as the main index that influences the effect of throwing because this device designs each parameter through structural design, reaches better effect of throwing.
Referring to fig. 14, the device is mounted at the rear suspension position of a semi-trailer agricultural vehicle chassis 500 through a hanging plate on the side throwing support frame 100, and the side throwing support frame 100 is used as a direct or indirect mounting base body of the following devices and mainly plays a role in supporting and mounting.
Referring to fig. 1 to 6, the main fertilizer spreading device 200 is used for realizing lateral fertilizer spreading, and includes two opposite disc mounting frames 201 arranged in an inverted-splayed inclined manner, the disc mounting frames 201 serve as mounting base bodies of fertilizer spreading discs 203, and angle adjusting devices for adjusting the inclination angles of the disc mounting frames 201 are respectively arranged between the two disc mounting frames 201 and the lateral spreading support frame 100; the bottom ends of the two disc mounting frames 201 are respectively hinged to the side throwing support frame 100, and the top ends of the disc mounting frames 201 are respectively hinged to the side throwing support frame 100 through the angle adjusting device; the angle adjusting device is an adjusting pull rod 202, one end of the adjusting pull rod 202 is hinged to the top end of the side throwing support frame 100, and the other end of the adjusting pull rod 202 is hinged to the lower portion of the disc mounting frame 201. Through the extension or shortening of the adjusting pull rod 202, the disc mounting rack 201 can be driven to swing upwards or downwards, namely, the adjustment of the inclination angles of the disc mounting rack 201 and the fertilizer spreading disc 203 mounted on the disc mounting rack 201 is realized. The adjusting rod 202 may be replaced by a hydraulic cylinder, an air cylinder, etc., which belong to the common knowledge in the art and are not described herein again. The opposite inclination angle of the fertilizer spreading disc 203 is controlled by the adjusting pull rod 202, so that the scattering angle of the fertilizer is controlled. The bottom end of the disc mounting frame 201 is connected to the side throwing support frame 100 through a bolt, when the bolt is loosened, the angle can be adjusted through the adjusting pull rod 202, and after the angle adjustment is completed, the bolt is screwed tightly to be fixed. Because the distance between two fertilizer scraping plates can change at the in-process at regulation and spill fertile disc 203 inclination, can lead to two fertilizer scraping plates to take place to interfere the collision when two fertilizer scraping plate distances are too little, and then can lead to middle fertilizer to appear uncontrollable problem when two distance between the fertilizer scraping plate are too big, in order to obtain the distance between the suitable two fertilizer scraping plates, consequently the bottom of side throw support frame 100 is provided with rectangular hole, and the bolt can carry out horizontal slip along rectangular hole, thereby changes two distance between disc mounting bracket 201 bottom.
Referring to fig. 1 to 8, two fertilizer spreading disks 203 and two disk power devices 204 for driving the two fertilizer spreading disks 203 to rotate are respectively mounted on the two disk mounting frames 201, the disk power devices 204 may be speed reducers, and power from a chassis 500 of a semi-trailer agricultural vehicle is transmitted to the speed reducers through a sprocket chain, so as to drive the fertilizer spreading disks 203 to rotate. For convenience of distinguishing the two fertilizing disks 203, they are defined as a left fertilizing disk 203 and a right fertilizing disk 203. The two fertilizing disks 203 are arranged oppositely in an inverted splayed inclined manner, and the two fertilizing disks 203 can also be described as oppositely arranged in a V-shaped inclined manner. In this embodiment, four novel fertilizer scraping plates 205 are respectively circumferentially arranged on each fertilizer spreading disc 203, and certainly, the number of the novel fertilizer scraping plates 205 is not limited to four, and may be three, five, six or more, and the fertilizer spreading discs are designed according to actual needs, and only the number of the fertilizer scraping plates 205 is changed within the protection enclosure of the present invention. During operation, the two fertilizer spreading disks rotate towards the same side, namely the left fertilizer spreading disk rotates clockwise, and the right fertilizer spreading disk rotates anticlockwise.
In the prior art, the fertilizer scraping plates on the left fertilizer spreading disk 203 and the right fertilizer spreading disk 203 are symmetrically arranged, that is, the fertilizer scraping plates on the left and right fertilizer spreading disks 203 are arranged in phase one-to-one correspondence, by adopting the arrangement mode, the movement positions of the fertilizer scraping plates on the left and right sides are synchronized, in order to avoid interference collision when the fertilizer scraping plates on the left and right sides move to the bottom simultaneously, the distance between the left fertilizer spreading disk 203 and the right fertilizer spreading disk 203 needs to be larger, that is, when the fertilizer scraping plates on the left and right sides move to the bottom, a gap exists between the left and right fertilizer spreading disks, and when large block-shaped hard impurities or fertilizers pass through the bottom, in order to avoid clamping the two fertilizer scraping plates and generating rigid impact, so that the damage of equipment is caused, the distance between the fertilizer scraping plates on the left and right sides must be increased, at this time, although the large block-shaped hard impurities or fertilizers can be accommodated, interference collision and equipment damage are avoided, but the fertilizer in the middle area between the two fertilizer scraping plates is not controlled by the fertilizer scraping plates any more and cannot be laterally scattered along with the rotation of the fertilizer scraping plates, so that a fertilizer blind area exists at the bottom; in addition, after the left and right fertilizer scraping plates simultaneously throw the fertilizer at the bottom end, the next side throwing can be carried out only by waiting for the movement of the next group of left and right fertilizer scraping plates to the bottom end, the fertilizer side throwing frequency is low, and the fertilizer discharging speed is slow.
In order to solve the above technical problems existing in the prior art due to the arrangement of the fertilizer scraping plates, in this embodiment, the novel fertilizer scraping plates 205 on the two fertilizer spreading disks 203 are arranged in a staggered manner in different phases, that is, the novel fertilizer scraping plates 205 on the left and right fertilizer spreading disks 203 are arranged in a staggered manner, the arrangement mode is shown in fig. 5, and this arrangement mode can prevent the novel fertilizer scraping plate 205 on the left side and the novel fertilizer scraping plate 205 on the right side from moving to the bottom end at the same time, that is, when the novel fertilizer scraping plate 205 on the left side moves to the bottom end, the novel fertilizer scraping plate 205 on the right side does not move to the bottom end, and at this time, the novel fertilizer scraping plates 205 on the left and right sides do not generate interference collision, and can contain massive hard impurities or fertilizers, thereby preventing massive hardboard card from generating rigid impact with the internal structure of the fertilizer scraping plate and ensuring the safety of the equipment; meanwhile, the distance between the two novel fertilizer scraping plates 205 can be set to be closer, the two novel fertilizer scraping plates alternately run to the bottom end and can contact the fertilizer in the middle of the bottom end, so that a fertilizer blind area in the prior art can be effectively avoided, and the fertilizer at the bottom end can be controlled by the fertilizer scraping plates; in addition, after the left fertilizer scraping plate laterally throws the fertilizer at the bottom end, the fertilizer can be thrown to the next side along with the movement of the right fertilizer scraping plate to the bottom end, so that compared with the same-phase arrangement mode in the prior art, the staggered arrangement of the different phases improves the frequency of fertilizer lateral throwing by one time, the fertilizer discharging speed is high, and the continuity of fertilizer throwing is good. The fertilizer scraping plates arranged in different phases can stagger vibration phases of the two rotating parts, so that the overall amplitude is reduced, and the stability of the equipment is improved.
The fertilizer scraping plates in the prior art are rectangular fertilizer scraping plates, namely, the fertilizer scraping depth is the same from the center of the fertilizer spreading disc 203 to the outside, and because the fertilizer scraping depth is always kept unchanged, the fertilizer in the middle area cannot be effectively controlled no matter the rectangular fertilizer scraping plates are installed in the same phase or in different phases, and meanwhile, a raised guide obstacle also exists between the left and right fertilizer scraping plates; in order to solve the problem, in the embodiment, the depth of the new manure scraping plate 205 is gradually increased from the center to the outer periphery of the manure spreading disc 203 to form a wide-bottom extension manure scraping plate. The wide-bottom epitaxial fertilizer scraping plates arranged in different phases can prevent interference and collision of the widened parts, and meanwhile, the design of widening the tail ends of the fertilizer scraping plates can effectively control uncontrolled fertilizer between the two opposite fertilizer scraping plates, so that the fertilizer containing capacity is increased, and the fertilizer application efficiency is improved. Along with the rotation of the wide-bottom extension fertilizer scraping plate around the axis, the extension part can scrape the convex part formed by the rotation of the rectangular fertilizer scraping plate into a cylindrical cavity to sweep away the guide obstacle on the fertilizer throwing path.
With reference to fig. 7 to 12, the wide-bottom extension manure scraping plate comprises a scraper mounted on the manure spreading disc 203Fertile board installation base 205a, scrape fertile board installation base 205a with it scrapes fertile board adjusting device to be provided with between the fertile disc 203 to spill, scrape fertile pushing riser 205b of installing on fertile board installation base 205a and be used for promoting fertilizer rotary motion, scrape fertile pushing riser 205b highly follow the center that spills fertile disc 203 increases gradually to the periphery and forms the inner narrow outer wide trapezium structure, it is provided with scraping plate top shrouding 205c to scrape fertile pushing riser 205 b's top, scraping plate top shrouding 205c and installing scrape fertile pushing riser 205 b's the material face one end that pushes away, install scraping plate reinforcing rib 205d on the back of the material face of scraping plate top shrouding 205 c. Referring to fig. 7 and 8, the direct cause of the scattering angle is the v at which the fertilizer particles leave the fertilizer applicator0yIs too large, and v0yThe fertilizer particles are driven by the rotation motion of the fertilizer scraping plate, so that a wide-bottom extension fertilizer scraping plate is designed for obtaining a smaller scattering angle, the component speed of the fertilizer particles when the fertilizer particles are separated from the fertilizer spreading device in the y-axis direction is smaller than the component speed of the fertilizer particles thrown by the rectangular fertilizer scraping plate in the y-axis direction, the fertilizer is thrown along the center line, and the scattering angle is reduced. In order to reduce the speed of the fertilizer in the y-axis direction, a straight line at the tail end of the fertilizer scraping plate is parallel to the ground, and a wide-bottom extension fertilizer scraping plate with the outer end widened is designed on a plane defined by the straight line and the central point of the disc. Compared with the jet flow thrown by the rectangular fertilizer scraping plate, the wide-bottom extension fertilizer scraping plate has a smaller scattering angle, a narrow jet flow is formed, the effective throwing distance is far larger than the width of a vehicle body, and the walking throwing and covering are uniform.
An inclination angle is formed between the fertilizer scraping and pushing vertical plate 205b and the fertilizer scraping and pushing plate mounting base 205a, referring to fig. 11 and 12, the fertilizer scraping and pushing vertical plate 205b is inclined backward from the fertilizer scraping and pushing plate mounting base 205a, so that fertilizer is not in vertical contact when contacting the pushing surface of the fertilizer scraping and pushing vertical plate 205b, at this time, the inclined pushing surface has a tendency of guiding the fertilizer to move from the bottom end to the top end of the fertilizer scraping and pushing vertical plate 205b, and along with the centrifugal movement of the fertilizer, more fertilizer can be laterally thrown from the position with the widened outer end, and the movement path of the fertilizer refers to fig. 11 and 12.
