DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to specific drawings.

[0026] like Figure 1As shown, the present invention provides a sand box transfer device, including a bracket 100 having a conveying space, a conveying mechanism 200 disposed in the conveying space, a plurality of transfer racks 300 that are opposed to the conveying mechanism 200 and can be accommodated in the conveying space for carrying the sand boxes, a base 400 disposed at the lower end of the bracket 100, and a driving mechanism 500 connected to the bracket 100. The conveying mechanism 200 includes a plurality of conveying rollers 210 that are rotatably disposed in the conveying space and can rotate around their own axes, and a driving unit 220 for driving the conveying rollers 210 to rotate. When the conveying rollers 210 rotate, the transfer racks 300 can move along the conveying space. The base 400 is provided with an annular groove 411, and the driving mechanism 500 can drive the bracket 100 to move along the annular groove 411. The plurality of transfer racks 300 each carry a sand box and transport it on each production line. The sand box transfer equipment is arranged at the corner of two production lines. The driving mechanism 500 can drive the bracket 100 to move along the annular groove 411. The transfer rack 300 can be arbitrarily turned to align with the unloading position of the upper production line. As the conveying rollers on the production line rotate, the transfer rack 300 carrying the sand box is transported into the conveying space. According to the transmission direction of the next production line, the direction of the bracket 100 is adjusted until the outlet of the conveying space is aligned with the feeding position of the next production line. The driving unit 220 is started, and the rotation of several conveying rollers 210 can transfer the transfer rack 300 together with the sand box to the next production line to complete the sand box transfer. The transfer process has a high degree of automation, which saves time and manpower and helps to improve work efficiency.

[0027] The bracket 100 includes two support assemblies 110 of identical structure and symmetrically spaced apart. These assemblies 110 comprise a hollow upper frame, two spaced support frames 112 disposed at the lower end of the upper frame, and a lower frame 113 disposed at the lower end of the support frames 112. Each lower frame 113 is provided with at least two guide rollers at its lower end that can slide within an annular groove 411. The identical structure of the two support assemblies 110 reduces assembly and processing complexity. The guide rollers move along the annular groove 411, allowing the bracket 100 to turn more smoothly around the annular groove 411.

[0028] One of the two upper frames is defined as the first frame 111, and the other is defined as the second frame 114. The inner walls of the first frame 111 and the second frame 114 are connected to corresponding bearing seats 211, each bearing seat 211 is installed with a bearing, and all conveying rollers 210 are rotatably connected to the bearings at the corresponding positions and are located between the first frame 111 and the second frame 114. The first frame 111, the second frame 114 and the conveying rollers 210 form a conveying space for accommodating the transfer rack 300, please refer to Figure 2, the upper ends of the first frame 111 and the second frame 114 are connected to a plurality of guide members 115, and the guide members 115 on the first frame 111 and the guide members 115 on the second frame 114 are symmetrically arranged to guide the conveying direction of the transfer rack 300. When conveying the transfer rack 300 carrying the sand box, the guide members 115 constrain the direction of the lower part of the transfer rack 300, and guide the transfer rack 300 on both sides of the transfer rack 300 to prevent the transfer rack 300 from deviating from the direction when being transported in the conveying space. In another embodiment, the guide member may be as follows Figure 3 The hollow guide member 116 shown can save production materials and reduce its own weight.

[0029] The driving unit 220 is mounted on the first frame 111, and the conveying mechanism 200 further includes a transmission mechanism 230 connected to the driving unit 220. Figure 4 The transmission mechanism 230 includes a plurality of double gears 231 and a plurality of transmission chains 232 disposed in the first frame 111 and connected to the plurality of conveying rollers 210 in a one-to-one correspondence. The double gear 231 connected to the driving unit 220 is defined as the driving wheel, and the remaining double gears 231 are defined as driven wheels. The driving wheel is connected to the adjacent driven wheels on both sides through two transmission chains 232, and each of the remaining two adjacent driven wheels is connected by a transmission chain 232. Figure 5 The double gear 231 includes a first gear 231A and a second gear 231B coaxially and spaced apart. The first gear 231A and the second gear 231B of the driving wheel are each meshed with a transmission chain 232. These two transmission chains 232 are respectively meshed with two driven wheels adjacent to the driving wheel. Specifically, the first gear 231A of the driving wheel is meshed with the first gear 231A of the driven wheel on one adjacent side via a transmission chain 232, while the second gear 231B of the driving wheel is meshed with the second gear 231B of the driven wheel on the other adjacent side via a transmission chain 232. For the remaining driven wheels, every two adjacent driven wheels are connected in the above manner, and the drive unit 220 is preferably a motor. When the drive unit 220 is started, the transmission chain 232 drives each conveying roller 210 to rotate about its own axis, thereby realizing the automatic movement and transportation of the transfer rack 300 placed in the conveying space, and moving the sand box is no longer time-consuming and labor-intensive.

[0030] See also Figure 6The transfer frame 300 comprises a frame 310, a plurality of reinforcing rods 320 arranged in a cross pattern in the frame 310, and a panel 330 connected to the upper end of the frame 310. The frame 310 has a smaller cross-sectional area at the ends than at the middle, and the four corners of the frame 310 are chamfered. Thus, the width of the ends is smaller. When the transfer frame 300 is accommodated in the conveying space, the height of the panel 330 is higher than the height of the support 100. When the transfer frame 300 is used for transfer, the guide 115 actually restricts the orientation of the frame 310. When the transfer frame 300 enters the conveying space or the production line, the smaller cross-sectional area of the ends of the frame 310 facilitates the smooth entry of the transfer frame 300 and avoids interference.

[0031] The base 400 comprises a ring-shaped seat 410, a first reinforcing beam 420 and a second reinforcing beam 430 connected to the bottom surface of the ring-shaped seat 410, and a ring-shaped groove 411 recessed from the top surface of the ring-shaped seat 410 towards the bottom surface of the ring-shaped seat 410. In the top view, the first reinforcing beam 420 and the second reinforcing beam 430 are arranged in a cross pattern. The first reinforcing beam 420 and the second reinforcing beam 430 serve to strengthen the ring-shaped seat 410.

The positioning block 412A is provided with a pin hole vertically penetrating the positioning block 412A for inserting the positioning pin 412B. The positioning hole 412D is detachably connected with a fastener for fixing the positioning side wing 412C to a fixed object, preferably the ground. In the production site, the fastener is preferably an expansion screw. The ring-shaped seat 410 is more stably fixed to the ground by fastening, so that the equipment operates more stably.
