Description

Technical Field

[0001] The invention relates to the technical field of artificial turf construction, and specifically provides a football stadium turf construction device and a construction method. Background Art

[0002] In large professional football stadiums, the lawns used are basically natural turf, but natural turf has high laying and maintenance costs, short service life and cycle, and the venue is not suitable for all-weather use. Therefore, in football stadiums in communities, schools, etc., artificial turf is basically used instead of natural turf; artificial turf, also known as synthetic turf or fake turf, is a ground covering made of artificial materials, designed to simulate the appearance and some functions of natural grass.

[0003] During the construction process of laying artificial turf, after the artificial turf is laid and fixed, quartz sand, rubber particles or other special filling materials are often filled under the artificial turf. The filling of the filling material can enhance the stability of the artificial turf and provide additional support, which helps the grass fibers of the artificial turf to restore verticality after being stepped on, and has the functions of increasing ground friction, improving drainage, and enhancing site temperature regulation. In addition, while filling the filling material, the grass fibers of the artificial turf need to be combed so that the grass fibers remain vertical. In actual construction, quartz sand is mostly used as the filling material. In the present invention, the filling material used in the construction of artificial turf is specifically quartz sand.

[0004] In the existing construction process, in order to reduce the intensity of manual labor and improve construction efficiency, a small vehicle is generally used to drive along the lawn, and quartz sand is scattered during driving, and the lawn can be combed by a comb at the same time. However, the following problems exist in the existing construction operation process: 1) When quartz sand is scattered, it is generally poured directly by hand, or automatically scattered through a quartz sand hopper. The spreading speed is fast, and the driving speed of the vehicle is affected by human factors. Therefore, the phenomenon of uneven quartz sand spreading is more prominent, thereby increasing the subsequent workload of evenly dispersing the quartz sand.

[0005] 2) Quartz sand is used as a filling material, which is generally screened and cleaned in advance to make the quartz sand particles uniform in size and remove the sediment contained in it to reduce the organic matter contained in the quartz sand. Although the quartz sand is pre-screened and cleaned, the treated quartz sand may cause secondary pollution due to improper storage and transportation, so that impurities will be mixed into the quartz sand again. In actual construction, the quartz sand is basically not cleaned again before being spread, so that the spread quartz sand will be mixed with impurities, which affects the construction quality for sports fields with high construction quality requirements.

[0006] 3) For the combing of lawn grass fibers, it is basically carried out in a straight line by combing with the help of the movement of the vehicle. The grass fibers of artificial turf are relatively dense, and the grass fibers of artificial turf will inevitably bend and entangle during transportation or construction. The combing effect is usually poor and the efficiency is low when simple linear motion is used for combing. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] like Figure 1 , Figure 3 and Figure 4As shown, a football stadium lawn construction equipment includes a filling bin 1 for filling material circulation, the filling bin 1 includes a pre-storage bin 11 and a screening bin 12 distributed up and down, a connecting channel 13 is arranged between the pre-storage bin 11 and the screening bin 12, the pre-storage bin 11 is used for pre-pour and store the filling material, in this embodiment, the filling material is specifically quartz sand, the screening bin 12 is used for collecting and storing the impurities generated by screening and filtering the quartz sand, in order to achieve the separation between the pre-storage bin 11 and the screening bin 12, a gate plate that can be inserted or withdrawn can be horizontally installed in the channel 13, in addition, the bottom end of the screening bin 12 is also provided with a bin opening for facilitating the removal of impurities, the gate plate and the bin opening structure are not shown in the drawings. It should be added that in order to improve maneuverability and construction efficiency, the equipment provided by the present invention can be docked and installed on an existing small automatic tractor. Specifically, the pre-storage bin 11 can be installed on the rear of the tractor through a fixed frame, and the rear of the tractor can be equipped with a lifting mechanism that drives the overall lifting of the equipment. The lifting mechanism can be a manual or electric structure. When lawn construction is carried out, the equipment can be lowered to a working height as a whole and raised again when not in construction.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, a filter screen 2 for screening and cleaning quartz sand is installed in the screening bin 12; the filter screen 2 includes a material screen 21, and the material screen 21 includes a screen frame 211 and a screen plate 212 welded and fixed on the screen frame 211, the screen frame 211 is in vertical sliding contact with the inner wall of the screening bin 12, the screen frame 211 is arranged obliquely as a whole, and the screen plate 212 is located at the inclined lower end of the material screen 21 and extends outward from the screening bin 12, and the extended end of the screen plate 212 is close to the rear of the tractor. It should be noted that quartz sand is generally screened in advance, so the particle size is uniform and meets certain specifications, and the screen plate 212 is a metal plate or a common woven screen with evenly distributed mesh processed, and the mesh size is smaller than the size of the quartz sand used for filling.

[0041] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, a plurality of slow - feeding plates 22 are hinged on the material sieve 21. The plurality of slow - feeding plates 22 are all located above the sieve mesh plate 212 and are distributed along the inclined direction of the material sieve 21. The slow - feeding plate 22 includes a U - shaped swing frame 221, and a grid plate 222 is welded inside the swing frame 221. The swing frame 221 is hinged on the sieve frame 211. On two inner side walls of the material screening bin 12 adjacent to the extending end of the sieve mesh plate 212, guide grooves 121 are oppositely welded, and the guide grooves 121 extend along the inclined direction of the material sieve 21. On both sides of the swing frame 221, sliding pins 2211 are oppositely welded, and the swing frame 221 is slidably installed on the two guide grooves 121 through the two sliding pins 2211. A plurality of rectangular grid holes 2221 are arranged on the grid plate 222 along the axial direction of the sliding pin 2211. In order to enable the quartz sand sliding down along the sieve mesh plate 212 to pass through the grid plate 222 normally, the grid holes 2221 are open on the side of the grid plate 222 close to the sieve mesh plate 212.

[0042] In the filter sieve 2 provided by the present invention, on the one hand, the slow - feeding plate 22 can rotate around the hinge axis, and on the other hand, the swing frame 221 slides along the guide groove 121 through the sliding pin 2211. Therefore, when the material sieve 21 reciprocates vertically close to the material screening bin 12, the plurality of slow - feeding plates 22 will swing reciprocally accordingly.

[0043] As Figure 1 、 Figure 2 and Figure 3 shown, on both sides of the outer wall of the filling bin 1, side frames 3 are symmetrically welded. Between the two side frames 3, a plurality of hair combs 4 for lawn combing are horizontally slidably installed. The plurality of hair combs 4 are distributed in sequence along their combing movement direction. The specific combing movement direction refers to the moving direction of the tractor. In order to enable the plurality of hair combs 4 to disperse the quartz sand being scattered during the process of combing the lawn grass filaments, the inclined direction of the material sieve 21 is set as a whole along the distribution direction of the plurality of hair combs 4, and the end of the material sieve 21 extending out of the material screening bin 12 is relatively closer to the tail position of the tractor than the entire row of hair combs 4, so that the scattered quartz sand first slides onto the lawn ground, and then the quartz sand can be dispersed multiple times by the plurality of hair combs 4 on the driving path.

[0044] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 and Fig. 9As shown, the hair comb 4 includes a comb body beam 41, and guide rods 44 with square cross-sections are welded at both ends of the comb body beam 41 in the length direction. The two guide rods 44 are horizontally slidably installed on the two side frames 3 in a one-to-one correspondence. A reset spring 45 is sleeved on the guide rod 44, and the two ends of the reset spring 45 are respectively welded to the end of the comb body beam 41 and the side bracket; the comb body beam 41 is provided with an embedding groove 411, and a compression strip 412 that can be elastically compressed is glued and fixed in the embedding groove 411. In this embodiment, the compression strip 412 is a silicone strip, and the embedding groove 411 is provided with a compression strip 412 that can be elastically compressed. A brush body plate 42 is embedded and installed, and two guide pins 421 are welded on the brush body plate 42 and penetrate vertically upward and are slidably installed on the comb body beam 41. The top of the guide pin 421 is fixed with a stopper 422 overlapped on the top of the comb body beam 41 by screws, and the brush body plate 42 is in contact with the compression strip 412; brush needles 43 are welded in an array on the brush body plate 42, and the brush needles 43 are made of steel needles. In order to avoid the steel needles from being inserted into and hooking the backing layer of the artificial turf during the combing process, the pointed end of the brush needle 43 is processed into a round head structure. Before construction, the entire equipment can be lowered through the lifting mechanism at the rear of the tractor, so that the tip of the brush needle 43 can contact the backing layer of the artificial turf as much as possible, and the brush body plate 42 slides up relative to the comb body beam 41 as a whole, and the compression strip 412 is in a compressed state. The compression strip 412 indirectly makes the brush needle 43 elastically press against the backing layer of the artificial turf. During the combing movement, the brush needle 43 floats up and down with the changes in the concave and convex ends of the contact end, which correspondingly reduces the movement resistance during the mobile combing. In addition, the brush needle 43 is kept in contact with the backing layer as much as possible. On the one hand, the brush needle 43 can touch the root of the grass silk, which can better realize the combing of the grass silk. At the same time, on the other hand, it can also better disperse the spread quartz sand while combing.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a driving mechanism 5 for synchronously driving the filter screen 2 and a plurality of wool combs 4 is also installed between the two side frames 3, and the plurality of wool combs 4 and the material screen 21 are all connected to the driving mechanism 5. The driving mechanism 5 includes a lifting frame 51 vertically slidably installed between the two side frames 3, and four interlocking guide pillars 53 are welded to the top of the lifting frame 51, and the four interlocking guide pillars 53 vertically penetrate and slide into the screen material bin 12, and the tops of the four interlocking guide pillars 53 are welded to the bottom end of the screen frame 211; a connecting rod 52 is hinged between the comb body beams 41 of the plurality of wool combs 4 and the bottom end of the lifting frame 51, and the two connecting rods 52 hinged to the adjacent two wool combs 4 are arranged in an inverted eight-shaped shape. The driving mechanism 5 also includes a driving assembly 54, and the driving assembly 54 includes a cam 541 horizontally rotatably installed between the two side frames 3, and the cam 541 keeps in contact with the upper end surface of the lifting frame 51, and the shaft end of the cam 541 can be fixed to the motor by docking, and the motor can be fixed to one of the side brackets, which is not shown in the figure.

[0046] Before construction, quartz sand is pre-filled in the pre-storage bin 11, and then the entire equipment is towed to the artificial turf field by a tractor; during construction, the gate of the filling bin 1 is opened, the tractor is started, and the equipment is driven to move along the field, and the motor connected to the cam 541 end is started synchronously, and the motor drives the cam 541 to rotate at a constant speed. With the cooperation of multiple sets of reset springs 45, the cam 541 makes the lifting frame 51 reciprocate along the two side frames 3. During the reciprocating lifting process, the material screen 21 and multiple wool combs 4 are driven to move synchronously.

[0047] The lifting frame 51 is lifted and lowered back and forth, and then the material screen 21 is driven to be lifted and lowered back and forth through four linked guide columns 53. The quartz sand falls from the pre-storage bin 11 through the channel 13 onto the screen plate 212. The reciprocatingly lifted material screen 21 is equivalent to a vibration screening effect, so that the quartz sand to be spread is screened and cleaned again by the material screen 21 to remove impurities that may be mixed in the quartz sand. The impurities can be collected in the screening bin 12; the quartz sand will pass through multiple buffer plates 22 in sequence during the process of sliding down the material screen 21, and at the same time, the reciprocatingly lifted material screen 21 forces the multiple buffer plates 22 to swing back and forth. The multiple buffer plates 22 slow down the speed at which the quartz sand slides, ensuring the time required for screening and cleaning, and the reciprocating swing of the multiple buffer plates 22 makes the quartz sand automatically and evenly dispersed, thereby improving the uniformity of quartz sand spreading. It should be noted that the material screen 21 is arranged at an angle, and can guide the quartz sand to slide down the slope. The main function of the filter screen 2 is to make the scattered quartz sand evenly dispersed, and the second function is to clean the impurities that may be mixed in the quartz sand.

[0048] The lifting frame 51 is lifted and lowered reciprocatingly, thereby pulling the comb body beam 41 to slide reciprocatingly between the two side frames 3 through the connecting rod 52, and the sliding directions of the two adjacent combs 4 are opposite through the distribution of the connecting rods 52 on the two adjacent combs 4. In the process of moving with the tractor, each comb 4 combs the grass silk along the driving direction, and at the same time reciprocates in the direction perpendicular to the driving direction, thereby improving the uniformity of combing the grass silk on the path through multi-dimensional movement, which can better promote the grass silk to remain vertical, and improve the combing effect of knotted and entangled grass silk. In addition, while combing, the brush needle 43 will also stroke the quartz sand, causing the quartz sand to be evenly distributed and filled in the grass silk layer.

[0049] like Fig.10As shown, in addition, the present invention also provides a method for constructing a lawn for a football stadium, which specifically includes the following steps: S1, cleaning, trimming the site to be paved, and laying the base layer: removing the old ground materials of the selected site, such as natural turf or concrete, to ensure that there are no obstacles; leveling and compacting the site foundation as needed to ensure a good drainage slope; crushed stone, gravel or sand layers are usually used as the base layer to provide stable and good drainage performance. For some projects, an impermeable membrane can also be laid on the bottom layer of the foundation to prevent groundwater from rising.

[0050] S2. Lay a cushion layer on the base of the site: In order to increase the buffering effect of the site and improve durability, a layer of special cushion material can be laid on the base.

[0051] S3. Lay fixed artificial turf on the cushion foundation: accurately cut the artificial turf according to the size of the venue, ensuring that the edges are neat and close-fitting; use special glue or other connection methods to splice multiple pieces of artificial turf into a whole, and pay attention to the joints should be as hidden as possible so as not to affect the appearance and use; use nails, wire mesh or other special fixing materials to firmly fix the artificial turf to the ground to prevent movement.

[0052] S4: Spread the filling material on the lawn surface by the construction equipment provided by the present invention, and comb the lawn fibers simultaneously. The details of this process can be seen in the above working process section.

[0053] S5. Clean up the site and conduct quality inspection: carefully trim the edges of the lawn, remove garbage and excess materials from the construction site, and keep the site clean; conduct a comprehensive quality inspection, including the flatness of the lawn, the distribution of fillers, and the overall appearance to ensure that it meets the expected standards and is accepted according to the standards.
